A Marine Food Web Bioaccumulation model for Cesium 137 in the Pacific Northwest
July 2, 2014
The Fukushima nuclear accident on 11 March 2011 emerged as a global threat to the
conservation of the Pacific Ocean, human health, and marine biodiversity.
On April 11 (2011), the Fukushimanuclear plant reached the severity level 7, equivalent to that of the 1986-Chernobyl nuclear disaster.
This accident was defined by the International Atomic Energy Agency as “a major release of radioactive material with widespread health and environmental effects requiring implementation of planned and extended countermeasures”.
Despite the looming threat of radiation, there has been scant attention and inadequate radiation monitoring.
This is unfortunate, as the potential radioactive contamination of seafoods through bioaccumulation of radioisotopes (i.e. 137Cs) in marine and coastal food webs are issues of major concern for the public health of coastal communities.
While releases of 137Cs into the Pacific after the Fukushima nuclear accident are subject to high degree of dilution in the ocean, 137Cs activities are also prone to concentrate in marine food-webs. With the aim to track the long term fate and bioaccumulation of 137Cs in marine organisms of the Northwest Pacific, we assessed the bioaccumulation potential of 137Cs in a North West Pacific foodweb by developing, applying and testing a simulation time dependent bioaccumulation model in a marine mammalian food web that includes fish-eating resident killer whales (Orcinus orca) as the apex predator.
The model outcomes showed that 137Cs can be expected to bioaccumulate gradually over time in the food web as demonstrated through the use of the slope of the trophic magnification factor (TMF) for 137Cs, which was significantly higher than one (TMF > 1.0; p < 0.0001), ranging from 5.0 at 365 days of simulation to 30 at 10,950 days.
From 1 year to 30 years of simulation, the 137Cs activities predicted in the male killer whale were 6.0 to 182 times 137Cs activities in its major prey (Chinook salmon, Oncorhynchus tshawytscha). Bioaccumulation of 137Cs was characterized by slow uptake and elimination rates in upper trophic level.

Recovery, remediation, decommissioning at Fukushima
Managing contaminated water involves removal of the sources of contamination and isolating ground water from sources
Full remediation and decommissioning of reactors at Fukushima may take a long time. Hasty schedules are not possible or expected as they clash with the safety of people. Water flowing over the melted cores of Units 1, 2 & 3 stricken by the earthquake and tsunami carries a cocktail of radio-nuclides. The integrity of the primary containment vessels of these reactors is not known. They have to develop the needed technologies to handle the cores; it may face its own trials and tribulations.
Fukushima now witnesses a beehive of activity. In April 2013, exactly two years after the accident, the site engaged 2950 workers in various remediation tasks. By February 2014, the work force grew steadily to 7150.
Mr. Naohiro MASUDA, chief decommissioning officer and president of Fukushima Daiichi Decontamination and Decommissioning Engineering Company presented updates of the progress thus far, and the future plans at an international conference organized by the Japanese Atomic Industrial Forum on April 13-14, 2015 at Tokyo.
He covered, among other topics: the present status of the plants; measures against contaminated water; fuel removal from the spent fuel pool and fuel debris removal.
The Tokyo Electric Power Company (TEPCO) maintains the reactors at cold shutdown stage by continuously injecting water into them. The operators removed spent fuel rods from the spent fuel pool at Unit 4 by Dec 22, 2014. Now they plan to remove fuel debris from Units 1, 2 and 3.
Maximum dose rate at the site boundary is only 0.03 mSv per year, as against allowed limit of one mSv per year.
Managing contaminated water is a humongous challenge. It involves removal of the sources of contamination, isolating ground water from sources and prevention of water leakage.
TEPCO uses 16 specially designed pieces of equipment each of which can remove one or more of the sixty-two different radio-nuclides including caesium-137 and strontium-90 from water. Each may process 250 to 1200 cubic metres per day. Tritium is a major issue. TEPCO is reportedly discussing with fishermen for its gradual release into sea.
Daily, about 400 tonnes of ground water enter the building. As this water gets contaminated, it has to be stored and decontaminated. Besides other methods, TEPCO plans to construct a frozen soil impermeable wall on the land side to prevent entry of ground water. The wall will use refrigerated coolant at minus 30 degree Celsius, running through pipes that have been placed vertically in the ground, to freeze the surrounding soil.
“There are many underground pipes and other structures associated with each of the four generating units. Building a watertight physical structure around all those obstacles would be nearly impossible and, even if it could be done, the construction would be more complex, time consuming, and disruptive.
It likely would also generate much more potentially contaminated excavated soil that would need to be safely disposed of,” TEPCO stated at its website…
The wall will be in place for six years, the period needed to drain and clean the contaminated water from the buildings and make them watertight.
According to Hiroshi Kainuma, Fukushima University, the yield of rice in Fukushima came down from 4, 45, 700T in 2010 to 3, 53,600 T in 2011. In 2013, it rose to 3, 82,600T closer to earlier years.
In 2012, 71 bags of food had radioactivity above the legal reference value. In 2013, 28; in 2014, no such bag was found.
Neither abortions nor abortion rates have increased in Fukushima. Divorce rate has not increased.
Birth rates lowered. Kainuma noted that the number of direct deaths caused by earthquake and tsunami in Fukushima was 1612; the number of disaster-related deaths due to evacuation was higher at 1793!
Decontamination specialists, with unenviable tasks assigned to them used, on large industrial scales, technologies which were successfully deployed on small scales. There were failures. Diligent auditors did not condone such ‘aberrations.’ You may express empathy or sympathy or hostility on that action depending on which side of the isle you are in!
The reactor owners, regulators and others responsible to operate the Fukushima Daiichi plants safely managed to melt the cores of three of them, throwing nuclear industry world-wide into disarray! Ultimately, the Japanese ingenuity and their expertise in robotics, miniature electronics, and precision engineering will win the day. Japan needs nuclear power; many plants will start operation, though presently only energy specialists look at them benignly.

Issues of Incineration Disposal of Agricultural and Forestry Radioactive Wastes in Fukushima Prefecture by Toshikazu Fujiwara
Makeshift incineration facilities in Minamisoma City, Fukushima Prefecture
June 2, 2015
The Fukushima Daiichi Nuclear Power Station accident released radioactive substances across a wide area of the environment. Currently, not only decontamination operations but also people’s everyday lives generate wastes that include high concentrations of radioactive substances. The Japanese government terms radioactive wastes from 8,000 to 100,000 becquerel per kilogram (Bq/kg) designated wastes. They are today stored temporarily at various locations, while at some point in the future, after reducing their volumes, the government plans to bury them in the prefectures where they were generated. In this article, Toshikazu Fujiwara, who is well-versed in the volume reduction of these contaminated designated wastes, discusses the issue. (Nobuko Tanimura)
Introduction
In Fukushima Prefecture, the Japanese Ministry of the Environment is promoting the Waste Volume Reduction Project, which, by means of makeshift incineration facilities, incinerates the combustible wastes that are specifically designated according to the level of contamination (at or over 8,000 Bq/kg) attributed to the radioactive substances emitted from the Tokyo Electric Power Company’s Fukushima Daiichi Nuclear Power Plant. The combustible designated wastes include agricultural and forestry byproducts such as paddy straw, feed crops, fallen leaves, and manure; sewage sludge; and wastes from home cleaning.
According to the project, the construction of 24 makeshift incinerators is being carried out in 19 municipalities in the prefecture, most of which are already in service.
The first of these incinerators to be constructed is located in Samegawa Village, Fukushima Prefecture. Having been built as a demonstration incinerator, it has the following formal purposes: 1) reducing volumes of wastes; 2) checking safety and associated factors as well as accumulating knowledge concerning the incineration of radioactive contaminated wastes exceeding 8,000 Bq/kg; and 3) determining the environmental impacts of radioactive cesium and other substances after incineration. However, the incinerator constructed in Samegawa was presumably a preliminary project in preparation for subsequent large-scale waste incineration projects.
Problems of the waste volume reduction project
(1) Deceitfulness concerning the project’s purpose
The waste volume reduction project states as its purposes improvement of the living environment for the restoration of the region and for the encouragement of the return of the people who used to live there, and making contributions to the progress of decontamination programs and the recovery of Fukushima Prefecture. Nevertheless, the waste volume reduction project totally ignores the risk of accidents, such as explosions associated with the incineration of radioactive contaminated wastes (the Samegawa makeshift incineration facilities exploded on the ninth day after the commencement of full-scale incineration services), environmental contamination, and health impacts on the people living in the neighborhood.
(2) Defects and procedural contraventions in the Special Measures Act
The legislation on which the wastes are designated and waste volume reduction programs are promoted is the Act on Special Measures Concerning the Handling of Environment Pollution by Radioactive Materials Discharged by the Nuclear Power Station Accident, established on August 30, 2011. This Act has the following fundamental defects: 1) while the procedure for designating wastes is stipulated, the procedure for removing wastes from the designation is not included; 2) the Act specifies that wastes exceeding 8,000 Bq/kg should be treated as designated wastes and wastes exceeding 100,000 Bq/kg should be stored in interim storage, but these radioactivity criteria are not scientifically persuasive; 3) the amounts of the designated wastes are overestimated because they were not determined by proper investigation; 4) the Act does not oblige Tokyo Electric Power Company, the company responsible for the emissions, to perform countermeasures, such as the prevention of radioactive substance discharge and the collection, disposal, and storage of contaminated wastes; and 5) the Act includes no procedural stipulation for information disclosure and accountability to, or the agreement of, local residents, all of which should be preconditions for waste incineration.
(3) Probability of environmental pollution and health risks
I assume that no country has so boldly promoted the incineration of radioactive wastes attributed to a nuclear power plant accident as in the Fukushima case presented in this article. Furthermore, the Ministry of the Environment has been mixing the designated wastes exceeding 8,000 Bq/kg with less contaminated wastes before incineration in order to reduce ash contamination per unit volume and thus prevent the ashes from exceeding 100,000 Bq/kg, over which they would need to be stored in interim storage facilities. The Ministry has repeatedly explained that the incineration of designated wastes exceeding 8,000 Bq/kg by means of the makeshift incineration facilities is safe, because the facilities are provided with bag filters that capture 99.99% of radioactive substances (mainly radioactive cesium particles) in the exhaust gas emitted through the incinerator funnels, reducing them to an undetectable level. However, gaseous substances and microparticles such as particulate matter 1.0 are known to be emitted through the filters, and bag-filter applications in conventional incinerators confirm that the filters break down easily. According to the makeshift incineration facilities test project commissioned by the Ministry of the Environment and performed by the Japan Atomic Energy Agency (JAEA) in Okuma Town and Iitate Village, Fukushima Prefecture, the mass balance analysis that compared the amounts of cesium in the wastes loaded into the incinerators and those in the output indicated that the whereabouts of 30% to 40% of radioactive cesium were unknown. The missing amounts of cesium may reside in the incinerator, ducts or funnels, or may be leaking from seals and other leak-susceptible locations in the facilities. If this is the case, incineration is highly likely to cause the spread of radioactive substances in a radius of several kilometers around the facilities, resulting in ground fallout and thus contamination of the land, increasing the health risks to locals. The Ministry of the Environment has performed no risk assessment in this regard.
(4) Financial unhealthiness
The budget the Japanese government has appropriated for this series of waste volume reduction projects is abnormally large. Overseas observers have previously regarded the huge spending by Japanese municipalities on the construction and maintenance of waste incineration facilities as extraordinary. The total cost of just the construction projects for makeshift incineration facilities that we know about, and which are planned to be used for as little as three months to three years, amounts to 400 billion yen. This amount does not include most of the cost of incinerator dismantling or site decontamination. The entire waste volume reduction project is an abuse of an enormous amount of tax revenue. If methods other than incineration were used, a considerable amount of expenses could undoubtedly be saved.
Let’s stop incineration and burial by proposing alternative methods, and establish a Fundamental Law on Radioactive Contamination Prevention!
In consideration of environmental loads and accident risks, the incineration and ash burial of radioactive wastes cannot be the optimal disposal system, no matter if the wastes are those generated anew by the Fukushima nuclear plant accident or the high-level radioactive wastes resulting from conventional nuclear power facilities such as reactors. We must come up with and propose alternative systems to put an end to incineration as quickly as possible.

NRA not informed of tainted water transfer
NRA not informed of tainted water transfer: Tepco caught mixing in highly contaminated basment water, claiming it is “rainwater.”
Tepco is transferring wastewater that is more radioactive than it originally stated. The company failed to notify Japan’s nuclear regulator of the change :
In May, officials found that water sampled at 4 sites at the plant’s port exceeded levels of radioactivity seen previously in the 2 years since monitoring began.
It’s believed the contaminated water came from a cracked and leaking hose inside the plant. The water from the hose flowed into a channel that led to the port.
Initially, Tepco said the hose contained wastewater that was a “byproduct of treating contaminated rainwater.”
But on Wednesday it was revealed at a meeting of the NRA that the utility had begun adding other highly radioactive wastewater to the water since mid-May.
Tepco says that as a result the wastewater in the hose was “likely more radioactive than it initially declared.”
Some of the water in the hose was groundwater mixed with extremely highly contaminated water that had pooled in the plant’s basement.
The hose cracked from being bent beyond the operational limit set by the maker. The utility had also failed to replace the hose despite questions about its durability.
NRA Chairman Shunichi Tanaka condemned the utility for its “utter failure to control the wastewater.” He ordered the company to continue monitoring and reporting on its handling of wastewater.

Wow! Fukushima Leak Could Cause an Explosion?
Paul Gunter seemed to be talking about the Hi-test radioactive sludge sitting at the bottom of the tanks. I thought this was about what soaked into the ground below the tank farm :
Paul Gunter, Beyond Nuclear, joins Thom Hartmann. Another day, another ominous development in Fukushima. According to new numbers from the Tokyo Electric Power Company – or Tepco – the plant’s Operator – as many as 10 percent of the nuclear facility’s containers may be leaking radioactive waste. And while the release of toxic chemicals into the environment is bad enough – this new problems comes with an added risk: it could cause a violent explosion. As one nuclear official told the Telegraph – since the leak was thought to be caused by a hydrogen build-up “If the concentration level is high, a spark caused by static electricity could cause a container to explode.”

Greenpeace releases confidential IAEA Fukushima-Daiichi accident report
The International Atomic Energy Agency report fails to accurately reflect the scale and consequences of the Fukushima disaster.
The International Atomic Energy Agency’s Board of Governors meets on June the 8th to discuss its confidential Fukushima-Daiichi Accident Summary Report. The report describes itself as ‘an assessment of the causes and consequences of the accident at the Fukushima Daiichi nuclear power plant in Japan that began on 11 March 2011.’
Greenpeace has received a copy of the report and we made it public last week. We’ve also conducted an initial analysis of the report and our findings are not good.
Yukiya Amano, the IAEA Director General says the report is ‘an authoritative, factual and balanced assessment, addressing the causes and consequences of the accident, as well as lessons learned.’
Yet our experts find it to be full of inaccuracies, uncertainties, and that it fails to address several highly important issues. We’ve sent our findings to Mr Amano.
Here are some examples.
- The IAEA admits that radiation monitoring was not working properly in the days immediately after the Fukushima disaster began.
- Despite this uncertainty, the report downplays the health risks to the disaster’s many victims.
- This means that the estimates of the levels of radiation the people of Fukushima were exposed to cannot be trusted.
- The IAEA’s analysis of the new safety regulations in Japan are superficial at best, and they offer no evidence in the report that the Japanese nuclear industry is operating to the global highest standards of nuclear safety.
- The reality is that there are major flaws in nuclear regulation in Japan with seismic and other threats to nuclear plants safety ignored or underestimated.
- The report dismisses the environmental impact of the disaster on animal life despite scientific investigations finding measurable effects on the region’s fauna.
- The report fails to acknowledge the uncertainties that still surround the causes of the disaster. Much of the critical systems inside the reactors that melted down have not yet been inspected.
These are just some of our initial findings. There are more to come.
(You can read our full analysis of the report here. The five part IAEA report is here: part one, part two, part three, part four, part five.)
So we see, as we saw in the aftermath of the Chernobyl nuclear disaster, the IAEA trying to create a narrative that minimizes the health and environmental impacts of Fukushima, while emphasising that lessons are being learned, including in making nuclear safety regulation more effective.
In short, the IAEA is moving to protect the nuclear industry instead of the people whose lives have been destroyed by the Fukushima disaster and those who may be affected by future nuclear accidents.
This is not a surprise, a central role of the IAEA is to promote the global expansion of nuclear power. The fact that all commercial nuclear reactors in Japan – 43 in total – remain shutdown is a direct challenge to the IAEA’s mission. That is the context in which the IAEA report must be seen.
After four years, the disaster in Fukushima is still unfolding and will take many decades to address. If the work to clean up the massive damage done is to be carried out effectively and future accidents avoided as much as possible, the IAEA must demonstrate that it can change the way it operates and quickly.
The IAEA at present serves only the interests of the nuclear industry and its drive for profit at the expense of the people who have pay the ultimate price for nuclear power’s failures.
Greenpeace is calling on Mr Amano and the IAEA to suspend their consideration of the report’s findings. An open and transparent process must be established that considers the views of the people of Japan, as well as independent scientists. We stand ready to meet with representatives of the IAEA to discuss our serious concerns.

Radioactive water leaks at Fukushima Daiichi: a never ending story
What a surprise! The operator of the destroyed Fukushima Daiichi nuclear plant, Tepco, says workers have found a leak of highly radioactive water at the plant’s site. They say the water flowed into the plant’s port. (Ocean)
We are all dumbfounded by such sudden unexpected horrible news, maybe we should start a worldwide crowdfunding project to provide them with sufficient plenty masking tape!
The operator of the crippled Fukushima Daiichi nuclear plant says workers have found a leak of comparatively highly radioactive water at the plant’s site. It says the water flowed into the plant’s port.
Tokyo Electric Power Company says the contaminated water was leaking from a hose connecting a wastewater tank and a building at the plant.
The hose had a crack about 1 centimeter long. The contaminated water was produced in a process to clean up rainwater tainted by radioactive materials at the plant.
Utility officials said the leaked water flowed into a nearby drainage channel and into the port.
They said they detected about 1,200 becquerels per liter of beta ray-emitting substances from water taken from the channel on Thursday. That figure was 40 times the level the previous day.
They said the figure rose to a maximum of 1,400 becquerels on Friday. The officials believe the leakage continued over the two days.
The company says concerns were raised about the hoses’ durability. It has been replacing them.
Authorities in Fukushima Prefecture have urged the company to conduct an investigation to identify the cause of the leak. They say the company should take thorough measures to prevent a recurrence.

LYING BY OMISSION ! “Tepco says all radioactive water in Fukushima No. 1 tanks filtered”
Their filtering systems can only removed 62 radionuclides out of the 1370 radionuclides present
The operator of the crippled Fukushima No. 1 nuclear plant said Wednesday it had finished filtering 620,000 tons of extremely toxic water stored in tanks on the premises of the complex to lower its radiation level.
Tokyo Electric Power Co. says the risk of radiation leakages from the water tanks is now much lower. However, around 400 tons of radioactive water is still being generated everyday as groundwater is seeping into the plant and mixing with tainted water more than four years after the nuclear crisis began.
According to Tepco, some 440,000 tons of the water has been treated through a water processing system that is said to be capable of removing 62 different types of radioactive material, with the exception of tritium. The remaining 180,000 tons has been processed through another facility capable of removing strontium, but still contains other types of radioactive substances and needs further treatment.
The highly radioactive water has been generated during the process of cooling the plant’s reactors, which suffered meltdowns after the facility was struck by a magnitude-9 earthquake and tsunami in March 2011.
When Prime Minister Shinzo Abe visited the Fukushima plant in September 2013, Tepco President Naomi Hirose pledged that the company would filter all the water kept in tanks by March 31, 2015 to reduce the amount of radioactive material it contained.
But the process has been delayed due to a series of problems with key water treatment facilities.

Looking for Know-How from Overseas
Japan and Tepco have now decided they need help.
4 years too late Japan.
Fukushima and the Crisis of Democracy: Interview with Murakami Tatsuya
The Asia-Pacific Journal, Vol. 13, Issue. 20, No. 1, May 25, 2015
Katsuya Hirano
Murakami Tatsuya is the former mayor of Tōkaimura or Tōkai village located approximately 75 miles north of Tokyo and 111 miles south of the Fukushima Daiichi plant.
Tōkaimura is considered the birthplace of nuclear power in Japan since the Japanese government built the first reactor for commercial use there in 1965 in collaboration with British nuclear scientists. As Mr. Murakami reveals below, the Japanese government at the time informed the residents of Tōkaimura only of the building of a nuclear research institute, not a power plant. As time passed, Tōkaimura became heavily dependent on the nuclear industry for its revenue and people’s livelihood. On September 30, 1999, the village had a nuclear criticality accident at the JCO nuclear reprocessing plant. It killed two people, left one person in critical condition, and exposed 667 people to radiation. They were the first victims of a nuclear accident in Japan. Mr. Murakami dealt with the emergency situation as mayor and subsequently became a vocal opponent of Japan’s nuclear energy policy. Since the Fukushima Daiichi Plant accident of 2011, he has been a leading figure in the anti-nuclear movement involving 24 village and town mayors, which calls for the abolition of all 54 reactors in Japan. The interview took place at his Tōkai residence in the summer and winter of 2014.
Tōkaimura as a Nuclear Village
HIRANO: Thank you for agreeing to this interview. Let’s focus on issues related to Japan’s nuclear energy policies, the Tōkaimura JCO accident, the Fukushima crisis, and their implications for democracy in Japan.
Tōkaimura’s population is currently 38,000 and its annual budget is 16.6 billion yen. The revenue generated by the nuclear power plant-related business is over 5.5 billion yen, which is roughly one third of total revenue. Considering the plant’s importance in the village economy, some critics say, it is unthinkable for you to have proclaimed an anti-nuclear position and led the anti-nuclear movement as mayor. Could you explain why you made that decision?
MURAKAMI: You correctly note that about one-third of the village’s revenue and operating expense is from nuclear facilities. Actually the budget funds are a bit more than 16.6 billion yen now, 18 billion in total. This year’s budget includes 4.5 billion yen of a financial savings fund that is budgeted for construction of an elementary and junior high school. This amount is added to the budget. So out of 18 billion yen, 5.5 billion yen would be revenue from nuclear-related industries.
We have two thermal power plants here, one of which started operating in 2013. Each plant generates 2.5 billion yen, so a total of 5 billion yen is expected from the thermal power plants. If we don’t include it, it will leave us with about 16 to 17 billion yen in budget. I can certainly say we rely heavily on the nuclear money.
If you look at other local governments with a size and population about the same as the village of Tōkaimura, their average budget is around 12 billion yen. You might wonder if these local governments struggle to provide adequate services to their people. The reality, however, is that there is not much of a difference in terms of the quality of life. In other words, Tōkaimura receives an excessive budget because of the plant. We really don’t need that much. If you have too much money, you tend to do evil. (Laughs.)
Another example of a local municipality hosting nuclear power plants is Genkai-Chō 玄海町 in Saga Prefecture where about seven thousand people reside. Their budget is 7 billion yen while other local governments with a comparable population receive 3 billion yen in budget. You wonder how 7 billion yen enriches people’s lives there, but the reality is that the town has to come up with something unnecessary for the community just to use up the budget, such as building a heated indoor swimming pool, tourist facilities or an impressive gymnasium and cultural center. These facilities were built for a town of seven thousand residents. It means that they are wasting the money. I guess it is “too much of a good thing.”
HIRANO: So it means that Tōkaimura can function well without the revenue from the nuclear power industry.
MURAKAMI: Absolutely! If we didn’t have nuclear power facilities, we would receive local allocation taxes just like other local municipalities. When I was mayor, I spent the budget on the improvement of social infrastructure, such as roads and facilities. It might be true that Tōkaimura may have a slight advantage over other local governments in the areas of welfare and education with extra revenue, but it does not necessarily mean that we can improve the safety and welfare of people significantly.
There are only 20 localities hosting nuclear power plants and related facilities nationwide. Can you believe that there are only 20 out of 1720 local municipalities? If you include Obama City in Fukui prefecture and Rokkasho village in Aomori prefecture, there will be 22. I have to wonder about the legitimacy of the special treatment in the form of subsidies that these 22 localities have been receiving from the joint power of the government and the nuclear industry. Actually, in situations like that, local residents tend to lose their motivation to work hard and do not make efforts to improve their lives. They just depend heavily on what they are given, and the dependency gradually sucks out people’s willpower and capability to think and act for the future of their towns on their own, just like drug addiction. I don’t think it is good at all.
HIRANO: You have been pointing out the aspect of nuclear power as a curse that deprives local community or government of its autonomy and independent-mindedness and leads to total dependency and as a result destroys the community.
MURAKAMI: You could say that. As for Tōkaimura, relatively speaking, it has managed to keep its local autonomy somehow, but once a possibility of nuclear power development is introduced to a local government, we can’t avoid the division between proponents and opponents. There are always people trying to profit by bringing nuclear power plants to their community while others fight the move because of the risks to the environment and themselves. This creates an incredible threat to the unity of a historically harmonious community. The conflict could last 20 to 30 years. Indeed it created a thirty-year human conflict and struggle in some local communities.
HIRANO: Did Tōkaimura experience this?
MURAKAMI: Actually no. In the case of Tōkaimura, the power plants had already been built without our knowledge. (Laughs.) What Tōkaimura agreed to host was a “Japan Atomic Energy Research Institute,” not nuclear power plants. Tōkaimura did not invite nuclear power plants, (laughs) so we had no idea we would end up hosting them. In those days [the 1950s and 60s], the government, the nuclear industry and some Liberal Democratic Party members [like Nakasone Yasuhiro1] and people like Shōriki Matsutarō2, were very enthusiastic about constructing nuclear power plants as a way of boosting national prestige and part of the Cold War strategy. The residents of Tōkaimura merely thought that they would host the Japan Atomic Energy Research Institute, but it turned out that the power plants came along as a part of the project.
It took 30 years for Kaminoseki-Chō in Yamaguchi prefecture as well as Maki-Machi in Niigata prefecture to settle their dispute over nuclear power plants. The same thing happened with Ashihama in Mie prefecture. Kushima City in Miyazaki prefecture once voted against the construction, but then it became clear that Kyūshū Electric Power Co., along with pro-nuclear power activists, has not totally given up the project. It is partly because Kyūshū Electric Power Co. has already acquired the construction site in Kushima City just as Chūgoku Electric Power Co. bought sites in Kaminoseki-Cho and Ashihama. Tohoku Electric Power Co. has also purchased land in the proposed area in Maki-Machi. Recently residents in Kubokawa in Kochi prefecture also voted against the construction plan, but that does not mean that the project became completely invalid. All these communities were bitterly divided and fought against each other for 30 or 40 or even 50 years regarding plans to construct nuclear power plants in their community.
The reason I began voicing concern about safety of nuclear power was the JCO Company’s criticality accident of 1999 in Tōkaimura. The accident occurred two years after I took office. While dealing with the accident, I gradually lost confidence in the government, and I became convinced that this country lacks adequate capabilities to maintain nuclear power plants.
In order to promote nuclear power, the government had kept all problems related to nuclear power hidden by putting a lid on them. But this will cause bigger problems in the future. That was exactly like the start of the Asia-Pacific War when Japan forced people to get involved and moved forward. I’m always conscious of how our country proceeded blindly with World War II. That is to say, it began covering up all negative aspects of history with tyrannical force. There is also the Emperor System to consider. I believe that under the System, Japan held illusions about its ability and failed to estimate reality objectively.
The same thing is happening with nuclear power. The government is promoting nuclear power by perpetuating the myth that nuclear power is totally safe just as during wartime Japan began promoting the Greater East Asia Co-Prosperity Sphere while hiding from the general public what was really going on. I thought the JCO accident occurred as a consequence of such unfortunate practice, and sure enough, it led straight to the Fukushima Nuclear Disaster.
After the JCO accident, the proponents of nuclear power did everything to suppress concerns and criticisms by further promoting the safety myth. They tightened their organizations, such as Power Reactor and Nuclear Fuel Development Corporation PNC, monitoring management more closely as well as limiting access from outside.
HIRANO: Was it done partly to prevent inside information from leaking?
MURAKAMI: Exactly. I saw this tendency more and more, and felt uncomfortable with it.
HIRANO: Japanese people were made to believe during wartime that the Kamikaze, the “divine wind,” would bring victory to the country and they went along with the wave of the times. Now they are facing a nuclear crisis brought about by believing blindly in the safety myth. You have repeatedly voiced concerns about the similarity between these two historical events as well as their developments.
MURAKAMI: As you know, Prime Minister Abe has been bragging that nuclear technology in Japan is the most advanced or the best in the world. I would say he is blinded by conceit. He is like a frog in a well; he does not know what he is talking about. I am afraid that he is arrogant and overconfident with no knowledge of his own limitations. His vision is so limited to what is going on in Japan that he cannot see the reality of the outside world.
We have a facility called J-PARC (Japan Proton Accelerator Research Complex3) in Tōkaimura. Japanese people praise this Japanese accelerator constructed by Hitachi Ltd. as a product of the world’s best or most advanced technology. I don’t deny that it is an excellent facility, but if you go to Europe, you will find a larger and more powerful accelerator called CERN. When it comes to electronic manufactures, Japanese people tend to think of only Hitachi, Toshiba and Mitsubishi, but there are many others in the world, such as Siemens and Phillips.
I said this at the time of the JCO accident when I was called as a witness by the science and technology committee of the House of Representatives. Technically speaking, it is possible to produce nuclear energy. But the problem is that this country has not established a system to regulate production. In particular, there is no separate organization to regulate nuclear power. I told the committee that it is very dangerous to continue under such circumstances. Japanese scientists might be bright enough to acquire this so-called “mega-science and technology,” but Japan has failed to create a system to control it. That explains why the JOC accident occurred. I have been voicing these concerns since then.
HIRANO: It sounds to me as if the problems lie within Japan’s policy makers and administrative bodies. For example, right after the JOC accident, when you were trying hard to figure out ways to evacuate locals safely and quickly, you could not get straight answers from either the national government or the prefectural levels because they themselves did not know what appropriate measures and actions to take. In the end, you had to come up with solutions by yourself and took actions accordingly. This example shows how unprepared Japan is to deal with a crisis like that.
MURAKAMI: Exactly. The same thing happened with the Fukushima Nuclear Disaster. With no crisis management system whatsoever, residents were forced to follow useless directions while dealing with tremendous uncertainty and despair. The administrative bodies should have created a system for risk management to respond in a way that would minimize radioactive contamination and exposure to locals long before the crisis occurred.
It is just unthinkable that a country like Japan, which is at high risk of earthquake activity, possesses 54 reactors in some of its overpopulated regions, and that there is no place to evacuate in the event of an accident. The government and top officials in the industry have avoided facing reality and have overlooked important safety concerns. Instead of facing the inconvenient truth, they concluded that a crisis was unlikely to occur in Japan.
At the time of the Fukushima Nuclear Crisis, the U.S. Nuclear Regulatory Commission responded right away urging Americans within 50 miles of the nuclear plants to evacuate, but the Japanese reaction was very different. Fukushima Prefecture ordered residents within 2 kilometers (1.2 miles) of the plant to evacuate. Later this was extended to 3 kilometers (1.9 miles,) while residents within 10 kilometers (6.2 miles) were instructed to stay inside before the evacuation order was extended to 20 kilometers (12 miles.)
Fukushima, Tōkai and Nuclear Policy
HIRANO: Both governments reacted to their respective nuclear disasters based on the same information, but the outcome was so different. How would you evaluate the different reactions of two governments?
MURAKAMI: I believe the U.S. government got the same information at that time. But the population affected was much smaller, which made the move easier and quicker. The Japanese government was dealing with tens of thousand people in the affected area, so unless they had been prepared, it would be difficult to act effectively. In fact, they did not even have planned evacuation routes or procedures for emergencies. The government’s utmost concern was to avoid panic among the residents. I’m sure the government officials panicked themselves, but they absolutely did not know what to do because they were unprepared to deal with such an emergency.
They were like, “What! Isn’t there more than one route for evacuation?” Before the accident, the implementation of emergency evacuation measures had not even been part of nuclear disaster prevention plans. In Japan, disaster prevention policies were originally written based on the premise that radioactive contamination and extensive radiation exposure would never become an issue because of the multiple forms of protection installed around the nuclear power facilities.
The publication of emergency evacuation plans would lead to questions and concerns about nuclear safety, so this was not even considered. According to the safety design regulatory guide for nuclear reactors, severe nuclear-related accidents would not occur in Japan because the power supply would be restored within eight hours of a station blackout. Before that, the emergency diesel generator would operate the isolation cooling system to provide enough water to safely cool the reactor until external power was restored. Based on the assumptions of the regulatory guide, there was no need to implement evacuation plans for residents.
This mentality reminds me of wartime Japan. They said that there was no need to think about being a prisoner of war because Japan would never lose. Don’t even think of becoming a captive. Before being humiliated as a prisoner, give your life for your country. I feel it is the same. I mean I see authoritarian power … well … the fragility of society.
HIRANO: There seems to be a lack of customs or habits in Japanese government and politics to make clear where the prime responsibility lies. For example, they built nuclear power plants, but they never thought through who would be responsible and how they should act in a crisis. All they did was build plants and focus on the benefits they would bring. That’s why Japan built 54 reactors on such a small and densely populated island.
MURAKAMI: That’s right.
HIRANO: Did you experience such irresponsible responses from government officials and representatives from the industry in the aftermath of the JOC accident?
MURAKAMI: What bothered me most was the fact that they closed the case without even trying to reflect thoroughly on the real cause of the accident. The explanation they came up with was that the workers had failed to use proper tools and equipment. They used the bucket and ladle rather than the dissolving tank to mix 18.8% enriched uranium oxide and nitric acid. Of course, the public was shocked to hear that and was easily convinced that the accident had been unavoidable under the circumstances.
But the real problems lay elsewhere and no one seemed to pursue it. The real problems were that they built the very small and potentially hazardous fuel preparation plant to deal with 18.8% uranium, while no major civil reactor elsewhere uses uranium enriched beyond 5% in residential areas, and the plant was not adequately designed to prevent the possibility of a criticality accident.
Moreover, they had inspected the plant only once since it began operation and failed to do a routine inspection for seven or eight years after that. Not only that, but the Power Reactor and Nuclear Fuel Development Corporation, which is the company JCO received the contract from, did nothing to supervise the operation. Even after the accident they left their responsibilities vague, concluding that the cause of the accident was “human error and serious breaches of safety principles” as exemplified in the use of the bucket and ladle. They claimed that it was a rare incident that was isolated from the mainstream workings of Japan Atomic Energy Research.
Now let me explain what was going on in the reactor in Tōkaimura at the time of the Great East Japan Earthquake. You might have heard that the tsunami wave almost spilled over the 70 centimeters (28 inches) protective seawalls, but seawater did enter into the pump chamber, narrowly avoiding reaching the ceiling by 40 centimeters (16 inches).
Inside the chamber, there were several seawater pumps intended to cool an emergency diesel generator, but one of the pumps was submerged under seawater and was not able to cool the generators sufficiently, so one of the three generators failed. We were very close to a station blackout.
With insufficient cooling power, the pressure of the reactor core rapidly increased and too much vapor was released, which prevented cooling water from entering. There is something called a main steam relief valve that is usually motor-operated in order to isolate the steam source from the turbine. Not being able to operate it properly or fast enough with the motor, technicians ended up operating it manually as many as 170 times. At the last stage, the valve was left open for a long time in order to keep the cooling system going. We nearly faced a station blackout.
Also, just one week prior to the earthquake and tsunami we finally completed construction to raise the height of the tide wall, and it was only two days before the earthquake when we finally closed the entrance path for the construction workers, which was a big gap in the wall. We were really lucky.
HIRANO: I read about it and realized how close Tōkaimura came to being as disastrous as Fukushima. We can say that it was a near miss. If a hydrogen explosion had occurred at Tōkaimura, the entire Kanto region would have been doomed, wouldn’t it?
MURAKAMI: There are 14 reactors on the shoreline from Onagawa in Miyagi prefecture to Tōkaimura, and I wouldn’t have been surprised if all these reactors had ended up failing in some way or another.
HIRANO: You mean that they were all dealing with similar dangerous situations?
MURAKAMI: Exactly. For example, Onagawa lost 4 out of 5 external power supply lines and the only one left barely managed to supply power to its nuclear power station units 1, 2 and 3. Fukushima’s No. 2 facility was in the same situation. All four reactors, 1-4, lost their external power supply to maintain the heat removal system, but reactor 3 quickly recovered to retain its function to stabilize other reactors. Then workers also had to restore power by laying more than five miles of heavy electrical cables by hand.
Of course if Reactor 4 at Fukushima No.1 had suffered more damage, there would have been no chance to save the Fukushima No. 2 facility. If it had failed, the Tōkai No. 2 reactor would have been severely damaged. It would have been like a chain reaction.
It tells you how catastrophic it could be for a country like Japan to house nuclear power plants. While about 150,000 people or so were living within 20 or 30 kilometers of the Fukushima No.1 plant, there are one million people living within 30 kilometers (18 miles) of the Tōkai plant and 750,000 people within 20 kilometers (12.5 miles).
HIRANO: It is unthinkable that they built the plant in an over-populated area like that.
MURAKAMI: It is crazy. Right now about 130,000 people in Fukushima have been evacuated from the exclusion areas, although it would be 80,000 or 90,000 people if we do not count voluntary evacuees. As far as Tōkaimura goes, the number of evacuees would be at least 10 times that of Fukushima, actually, it might be 20 times.
HIRANO: What if you include voluntary evacuees?
MURAKAMI: Yes, if we include them, it would be estimated at 1.5 or 1.6 million people. Who would guarantee the livelihood of these people?
HIRANO: It would be hard. The government would go bankrupt.
MURAKAMI: Also there are many Hitachi manufacturing divisions and plants in this area, and it is impossible to compensate for damages to the company. They are estimating that it would cost 5 trillion yen to compensate for 80,000 people, so it is absolutely impossible to think about compensating for the damage caused by Tōkaimura No. 2, even with state compensation. It means that victims of a disaster at the Tōkai plant would have no choice but to drop the case altogether. They wouldn’t be able to expect anything.
HIRANO: I don’t think it would be an option to find a place to relocate that many residents at once, either.
MURAKAMI: I don’t think so, especially within this country. If it were possible, they would have relocated the victims in Fukushima by now. Speaking from the examples of Chernobyl, Fukushima should have been declared uninhabitable, especially to raise children.
HIRANO: I agree. Mr. Koide Hiroaki of Kyoto University4 claims that it does not solve anything just to give money to the victims. At least families with small children should have been given new land somewhere safe to start their lives again. The government should have provided them with a new village and community to live.
MURAKAMI: But I don’t know if we can find such a place in this country. In fact, I thought about the possibility of relocating the entire Tōkaimura myself. The news about the Fukushima crisis chilled me to the bone. As I mentioned, we were so close to having a similar situation, so I started thinking about relocating the entire village and in fact found a place in Hokkaido. (Laughs.)
HIRANO: Hokkaido, is that right? (Laughs.)
MURAKAMI: Yes, I thought about the possibility of relocating 38,000 residents and have them start dairy farming and cultivating new land in Hokkaido. I know it should not cost as much to buy land there as in Tōkaimura. I even visited the area. If it doesn’t work, I thought, other alternatives would be Australia or our sister state, Idaho. (Laughs.) Of course, we would first need to acquire water rights there, but we could start working on an irrigation system in the desert. It is exactly the land cultivation project of the 21st century. But it is often the case that mass relocation like this would face discrimination in the new land. (Laughs.) If we are relocating with one or two people, we would be welcomed, but a mass relocation would be different no matter where.
Actually this is a serious matter in the sense that Tōkaimura alone cannot come up with some kind of solution if an accident occurs at the Tōkai No.2 reactor. All neighboring communities, such as Mito city, Hitachi city and Hitachinaka city, need to be involved in the decision over what to do in a scenario like that.
Struggle for Local Autonomy
HIRANO: Do you have any communication or collaboration among the neighboring cities and villages?
MURAKAMI: Yes, we do. With Mito city [the capital of Ibaraki prefecture] in charge, we’ve formed a central district chief committee 県央地域首長懇話会 with mayors from all local municipalities as far north as Tōkaimura and as far south as Omitama city. Also, after the Great East Japan Earthquake and the subsequent nuclear power plant accident, I organized a committee with mayors from five adjacent municipalities surrounding the nuclear power plant in Tōkaimura, including Hitachinaka city, Mito city, Naka city, Hitachi city and Hitachi Ohta city.
According to the safety agreement with Japan Atomic Power Company, the Tōkai nuclear reactor could resume operations as soon as the company obtains approval from both Tōkaimura and Ibaraki Prefecture, but now these adjacent municipalities are demanding a part in the decision-making process. It is quite understandable because they would receive as much damage as Tōkaimura. The population of Hitachinaka city is about 160,000, and Naka city has 60,000 to 70,000 people. The mayors in Naka city and Hitachinaka city are working hard for it.
HIRANO: So are these local governments clearly expressing opposition to bringing the nuclear reactor back on line?
MURAKAMI: Well, not explicitly. Tōkaimura has a new mayor now, but I think he and I share similar opinions. As you know, these mayors are not totally free to say whatever they want. They need to take their political position and situation into consideration, such as future elections and various positions of the political party they belong to, so they would rather leave the issue vague in order to avoid political conflict. (Laughs.) But the mayor of Hitachinaka city, Mr. Honma, has expressed his opposition openly. The mayor of Omitama city explicitly said no to restarting the reactor. He himself is a dairy farmer. And the former mayor of Shirosato-cho and of Ishioka city, which is not a part of the committee, also expressed his opposition. It is the same with the mayor of Hokota city, whose main industry is agriculture. The mayor of Ibaraki-machi stays rather vague because its neighboring town, Ōarai-machi, is highly dependent on nuclear power. In fact, the industry is tactful in enticing mayors.
HIRANO: Do you mean that a mayor might be getting large “donations” from the industry during the election?
MURAKAMI: Hmmm, I don’t think that is the case here in Tōkaimura. I don’t believe that is the case with Ōarai-machi either, because in Ōarai most city council members are associated with the Japan Atomic Energy Research Institute (JAERI) and Japan Atomic Energy Agency (JAEA) anyway. I don’t think political donations are the issue. I would say their influence is not from money but the way they approach local government. They are very polite and humble. You know, these top elite scientists with a PhD are graduates from prestigious schools like Tokyo University, but they never act arrogantly. If these respectful, elite gentlemen come to see you and ask for a favor, I can see how it could be sometimes hard to say no to them.
When I was still mayor in Tōkaimura, I received a request from the Japan Atomic Power Company (JAPC) to build unit 3 and 4 reactors, but I was not enthusiastic about building additional reactors. At the time of the Tōkaimura nuclear accident in 1999, the plan to build J-PARC (Japan Proton Accelerator Research Complex) had already been finalized and the construction had begun, so after the accident I decided that we should end the dependency on nuclear money as a way for community building and development, and that we should focus more on becoming a research-oriented community.
That’s how the concept of “Tōkai Science Town” was born. This was something we had been discussing even before the Fukushima Disaster. Since the completion of J-PARC, I have spoken about this on various occasions as “the dawn of a new era for Tōkaimura.” Of course, we will lose a host of subsidies, property and income tax revenues.
Some might think that all we need is to invite facilities or industries that bring a lot of financial resources to our community. Such logic seems to me too simple. I wanted to free us from dependency on so-called easy money.
Judging from how the Japanese economy has been changing, I could tell that the new era has come. For Tōkaimura we should shift direction and create our community utilizing social and cultural values that J-PARC would bring. I have been saying this since a few years prior to the Fukushima nuclear accident.
First, we came up with the idea of “Tōkaimura Advanced Science Research Cultural City” 東海村高度科学研究文化都市構想. I intentionally included the word “culture” in it. I believe we came up with this concept around 2003 or so, but we did not move forward with it until about 2010 when we organized a committee to work on a concept for a science town. We had our first meeting in June. At that time, I knew that nuclear dependency would eventually lead to a dead end.
Under the influence of Abenomics5, Japan is mainly focusing on GDP expansion, but I know that this will end soon. In order for local communities to survive economic downturn, I believe that we need to work together to depart from the GDP expansion principle and obsession with economic developmentalism. We need to focus more on primary industries like agriculture and the craft industry or welfare. If we strengthen these areas, I know our town will attract a lot of people to settle in our community. I have been advocating this for quite a while even before the Fukushima accident.
HIRANO: Why did you include the word “culture” in the new concept for Tōkaimura.
MURAKAMI: I wanted to emphasize that what we are trying to create for our community is not all about money.
HIRANO: So, it is not money but culture or rather what people create and value. If it is only science without culture, people in general might associate Tōkaimura with the money or profit that science and technology could bring in.
MURAKAMI: That’s right. The first thing that could come to mind might be money when we are planning the future of our community, but I wanted to emphasize that money and numbers alone cannot make us happy. I don’t think it is necessarily true that people with income of 5,000,000 yen a year are much happier or have a better life than those who earn 3,000,000 yen a year. I really don’t think so.
Many people ask me what I am going to do to maintain the economy if I abolish the nuclear power plants. First of all, I am not really certain that nuclear power would really enrich our lives. This is a brochure that someone put together explaining what directions we would like to take in the future to recreate our community. This does not necessarily reflect exactly what I have in mind, but states that we need to depart from an economy-focused or growth-oriented society and that it is time to establish local autonomy.
Instead of pursuing economic gain, we should focus on how to increase cultural value and social value in our lives by utilizing what we already have or by creating something new by applying our wisdom and experience. For example, we have J-PARC here in Tōkaimura and we can make that our asset. We have about 100 to 150 visitors from overseas at J-PARK every day, and we have about the same number of people from all over Japan. So we need to create a community to welcome and accommodate these people.
HIRANO: I’m very interested in your concept of local autonomy. Generally speaking, local autonomy implies a sense of being closed or exclusive, but what you are advocating here is rather to open a door to the world and contribute to transnational interaction by utilizing local assets and features.
MURAKAMI: Exactly. In 2011, before the Great East Japan Earthquake occurred, we organized a meeting to talk about the basic philosophy, goals and concept for the future of our community. We called it the Tōkaimura 5th Comprehensive Plan. About 150 residents showed up and the basic philosophy they created together was “community building that reflects residents’ wisdom and knowledge for all living things in the present and future.” The plan elaborates on this philosophy in the following way: 1. we will create and pass down the wisdom that enables us to learn from the past, reflect on the present, and build the future; 2. we will use villagers’ wisdom to create together a society that treats every individual with respect and also provides her/him with various opportunities to fulfill her or his life; 3. we will respect the harmony and connectedness of nature and life and gather all our wisdom to create a community filled with vitality that generates new ways of living. They came up with this idea all by themselves as the future goal for Tōkaimura.
HIRANO: It is really impressive, isn’t it? I wish every local government would adopt this democratic process for community building. Did they meet multiple times before they finalized their plans?
MURAKAMI: Yes, and I did not make any suggestions to them as mayor. Interestingly enough, what they came up with perfectly matched what I had in mind. I think that it proves that my concern that “Abenomics” prioritizes economic growth is widely shared by citizens. It seems natural that people have started questioning the direction in which Abenomics is leading the country.
HIRANO: We can say in some sense that nuclear power is a symbol of an economy-focused society.
MURAKAMI: Exactly. It is a typical example. Usually nuclear power plants are built in impoverished rural areas, and local communities become heavily dependent on the money nuclear plants bring them.
Speaking of Tōkaimura, we have a lot of inns, but rather than being for ordinary travelers, they are for nuclear power plant workers, so the accommodations are quite simple and shabby. They only eat and sleep there, often sleeping in one big room together and sharing a bathroom. (Laughs.) Of course some of the inns are called “business hotels,” but if regular customers stay there once, they won’t want to stay again. (Laughs.)
When we had completed J-PARC, I suggested that the inn owners renovate their rooms to accommodate researchers and students who were coming to visit the facility from all over the world, but they refused, saying “No, thank you.” They said that it is too much trouble especially having visitors from overseas. They can operate their businesses fine. They are not motivated to do anything extra.
HIRANO: Do these owners also support nuclear power?
MURAKAMI: Sure. Some of the inns are even located in the middle of a rice field. When I first became mayor, I did not understand why there were inns in the middle of nowhere, but then I gradually came to understand.
HIRANO: Nuclear dependency has created a kind of distorted structure in the local community.
MURAKAMI: Exactly. Indeed, we have a lot of inns everywhere in this town. While there are some within one kilometer of the power plant, some are located in places that do not make sense, for example in places where you can’t even catch a taxi, instead of near the train station or downtown. They are all for the plant workers, and the inn owners can make a decent living off of it. The nuclear power company has a contract with these inns, so the owners do not have to do anything to attract customers. They can do good business without any effort. The same goes for stationery stores and clothing stores in Tōkaimura. They don’t do business with residents, because they don’t need to. The nuclear power company’s branch offices buy their goods regularly, so these businesses are stable and secure without extra work.
HIRANO: That’s precisely what nuclear dependency means, doesn’t it?
MURAKAMI: Exactly. It is called dependency not only financially but also mentally. The population in Tōkaimura is growing with young families moving into town. We have a lot of babies, but business owners have no interest in them, even though I suggested that they target young families.
HIRANO: In this structure of dependency, you can’t cultivate and grow other local businesses that would accommodate needs of residents.
MURAKAMI: That’s right, as long as our industrial structure disproportionately depends on nuclear-related business.
HIRANO: I see. I can imagine you must have dealt with a lot of criticism when you began advocating for the new town concept.
MURAKAMI: I do not personally remember having heard much criticism, but I am sure there were complaints about what I was advocating, and also there were people who were hoping that I would lose the next election.
Anyway, I am skeptical that under the influence of the nuclear industry we will succeed in cultivating other businesses independently. Construction companies and machine processing companies are fine as long as they keep ties with the nuclear power industry. In other words, they are no longer competitive. Right now, however, operation of the Tōkaimura reactor is suspended, so business owners won’t be making money and they may go out of business.
HIRANO: Futaba town6 in Fukushima, which was once a declining town, was also trapped in a vicious cycle by continuing to build reactors in exchange for substantial subsidies from housing nuclear power plants.
MURAKAMI: That’s right. Futaba had once struggled financially so badly that it was designated for fiscal consolidation. When the town reached the brink of bankruptcy, it again turned to Tokyo Electric for financial help and approved a plan to build two new reactors, No.7 and No. 8. When the town began to recover, the Fukushima disaster occurred, and the evacuation of the entire community followed. I remember back then, the town’s former mayor Mr. Idogawa was working desperately to bring nuclear plants to the town. But now he has become a vocal critic of nuclear power. He himself was forced to evacuate to Saitama and has not been able to return.
Now let me talk about the reaction I received from the residents in Tōkaimura after I began opposing nuclear power. Although some of them might have been hoping that I would lose the following election, I did not really experience protests or personal attacks. Most of the residents I dealt with at that time were very supportive of me, although I am sure behind my back there were a lot of people who fiercely opposed what I was standing for. I also got a lot of support and encouragement from former or retired employees at Hitachi Ltd. and Atomic Energy Agency.
HIRANO: You mentioned earlier that issues of nuclear power plants often divide a town. Did you also see the problem among the city council members in Tōkaimura?
MURAKAMI: Yes, they were divided in half. At first, not a single council member clearly opposed nuclear power, but after discussing a petition for decommissioning the Tōkai No. 2 reactor with our nuclear special committee for a year or so, some members began making their anti-nuclear stance clear. They are not the majority yet, but I would say about half of the council members oppose nuclear power now. I can say the same thing about the residents. About half of them are anti-nuclear while the other half supports it.
HIRANO: What made you decide to run for office? Is it because you had visions for the town?
MURAKAMI: I wouldn’t say it was mainly for my hometown although I was hoping to be able to do things to eventually benefit the town. One reason why I began thinking of running for office was that in 1997 the decentralization promotion committee issued the second recommendation. It stated the basic concept of autonomy for local governments by giving administrative authority and responsibility as well as legislative power to local government. I knew that the era of political decentralization and shifting power from the long-standing centralized government to local government would be coming. This hope eventually made me enter politics.
Of course, I wanted to change the way the local government had been operating here. I had been observing that local governments always turned to prefectural government, and prefectures turned to national authority. Simply speaking, a prefecture is nothing but a national government agency, but local governments all turn to it. All local officials thought about was how to get things done through petitioning the central government. Instead, I wanted to get townspeople involved in the process of creating their own community by putting them in charge. I found it very rewarding to lead, and I also wanted to change the way the local office would operate by staffing it with new officials. That was my ideal.
HIRANO: Did you also think at that time that you would like to change the way the local economy had been working for Tōkaimura by shifting from nuclear dependency?
MURAKAMI: Actually I did not have that vision yet. Tōkaimura was financially well-established, so at the beginning I thought anything would be possible as long as we put in effort. Then we had the JCO accident within two years after I took office. While struggling to find a way to pull our town together and recover from the accident, I decided to turn to the city of Minamata7 for help. I visited there and met the mayor and residents. They taught me a lot. In those days, people just believed that the only way to develop local towns was by getting help from the central government or bringing large corporations to the area, but I learned from Minamata that we rather need to break away from the old mindset focusing on economic growth and development and create a sustainable society, focusing on and paying more attention to protecting the environment and respecting human beings. In that sense, Minamata was my starting point.
HIRANO: It is almost ironic how history is repeating itself. A similar set of problems to what Minamata had suffered arose after the Fukushima accident.
MURAKAMI: That’s right. Exactly.
HIRANO: It means that lessons learned from Minamata need to be applied in order to deal with the situations people in the larger Fukushima area are facing now.
MURAKAMI: You are right. I also see that if we keep depending on Abenomics, local towns and cities will decline rapidly.
HIRANO: So you mean that sort of Neo-liberalism?
MURAKAMI: Neo-liberalism, that’s right. I thought about this at the time of the Koizumi administration (2001-2006). This is how Prime Minister Koizumi thinks. Why are you living in such a remote mountain or on an isolated island? It costs too much to support you, so move out from there. I will give you three or four hundred thousand dollars so that you can live in a city. It’s cheaper. If you stay in such remote areas, we have to fly a helicopter to get you to a hospital when you get sick. It costs the government too much money. (Laughs.) That’s what I call Neo-liberalism.
HIRANO: They cut off everything local.
MURAKAMI: Cut off, cut off. That exactly happened with the merger of cities and villages. It was the Great Heisei Mergers.8
HIRANO: Koizumi planned to establish small cities in local areas through consolidation and eradicate “useless” rural communities to achieve maximum economic efficiency.
MURAKAMI: That’s right. He wanted to get rid of them, claiming it would greatly improve economic efficiency for the country. That was what Koizumi’s reform efforts were all about. And the trend has been accelerated by Abenomics now. Mr. Masuda Hiroya, a close associate of the Abe government, published a rather disturbing statement that about half of Japan’s regional cities may disappear by 2040. I don’t believe it would happen because the theory is based exclusively on economic rationality. When we think about economic rationality and people’s values, they may conflict.
What national wealth means is, as the court rulings of the Ohi nuclear trial states, that people live in a rich land and the people’s livelihood should be enriched by it. That’s what national wealth should mean, but the idea of economic efficiency comes only from the perspective of monetary wealth.
“National Policy” and “Natural Disaster”
HIRANO: Let’s talk about the concept of “national policy” (国策). In your book, you talk about how the concept plays a psychological role in people’s mindsets. I was impressed with your keen insight.
MURAKAMI: It is said that nuclear energy policies were implemented as a national policy, but it is not clear who actually decided this. It is true that the government has been in charge of its promotion, but I have to wonder how much the opinions and feelings of residents or local governments that house nuclear reactors have been taken into consideration under the name of national policy.
Then I looked the word up in a dictionary, and found that the term “national policy” is associated with colonialism. According to the Kōjien dictionary, the colonial powers created national policy in order to control and promote the development of colonies. I indeed thought it explained well the true nature of national policy. The term is self-explanatory; in other words, it is a policy adopted by the government.
There are many policies that fit under that category, but only few are given the title of “national policy”. I believe nuclear energy policy alone is referred to as a national policy nowadays. Mass media still often uses the term without hesitation, but it is only during wartime when the term “national policy” is clearly applied. For example, Basic National Policy Guidelines9 and Imperial National Policy Guidelines10 during the Asia-Pacific war – they are all associated with war.
HIRANO: That’s right. National policies implies mobilization of the whole country; that is the premise.
MURAKAMI: Exactly. In that sense, national policies mean that people are forced to make sacrifices for their country. In other words, it is for a greater cause and that’s why it is a virtue to dedicate one’s life to their country. The term “national policies” implies this, doesn’t it? Even though it is an era of decentralization of power, some people in local areas regard nuclear energy as a national policy and dismiss their opponents as people who are against national policies. We still have people like that in Tōkaimura nowadays.
Even some of the local government chief officers, especially ones hosting nuclear power plants, say they are hesitant about speaking out against or even making decisions on nuclear power themselves, because they are national policies. It seems to me all they are doing is avoiding their responsibility. Saying that it is something the government decides, they keep silent about whether or not nuclear plants should be reactivated. The central government also tries to silence local governments in the name of national policy. This is how national policy works.
HIRANO: It is the most anti-democratic approach, isn’t it?
MURAKAMI: Exactly. It’s the most anti-democratic way. It is just like the Liberal Democratic Party’s draft constitution. (Laughs.) According to it, the government matters most, not the citizens. I think the mass media should really expose the fact that nuclear energy policies are anti-democratic.
HIRANO: Now let’s talk about another problematic language – natural disasters and man-made disasters. I heard that it is commonly accepted in Japan to treat the Fukushima nuclear accident as a natural disaster. People say that this kind of large earthquake does not occur often, maybe only once every thousand years, so there was nothing we could have done to prevent the disaster, and we should just move on.
MURAKAMI: It is actually dangerous to think that way. They say only once every thousand years, but that means it may happen every thousand years. It seems to me that it is very high frequency. And although they say only once every thousand years, there was the huge trench-based earthquake off Indonesia’s Sumatra Island in 2004 and in Chile in 2010, as well.
Around 2006, we had background checks for earthquake resistance on the nuclear power plant in Tōkaimura, but they were mainly concerned about the active fault due to the Niigata-Chuetsu Earthquake of 2004. So I told them that the Japan Trench is lying right in front of us within 150 kilometers off the coast, and asked them if this posed a safety concern to us, considering what had happened at Sumatra Island. They said there was no need to worry about it because the Japan Trench lies where the pacific plate subducts smoothly beneath the continental plate, unlike off Sumatra Island, so energy won’t be accumulated. They assured me saying we would not experience a huge earthquake like the Indian Ocean earthquake here in Tōkaimura. They are employees at a nuclear power plant who are in charge of earthquake resistance Although it is said that earthquakes like that may happen every thousand years, they are happening more frequently. For some reason, someone made this theory based on the Jogan Earthquake of the year 869. I don’t believe it.
HIRANO: In fact, there was the Hōei Earthquake in 1707.
MURAKAMI: You are right. There was 1855 Edo Ansei Earthquake, as well.
HIRANO: Exactly.
MURAKAMI: Of course, we can’t forget the Great Kanto Earthquake of 1923. Anyway, the claim that it only happens once every thousand years is just deception. Even if it were true, we should not think that there is nothing we could do. We build nuclear reactors on the earth and in nature. It means that we should expect that something unpredictable and beyond human ability might happen. They might also blame the tsunami for the Fukushima disaster, but how can they say that after building nuclear reactors on an earthquake-prone archipelago? I believe that once an accident happens with nuclear power, there is no going back. We are doomed. This should be the scientific spirit.
HIRANO: In some sense, the fact that it was “unexpected” should not be an excuse.
MURAKAMI: That’s right, because we are the ones who created something that should not exist to begin with. As you know, the atom does not exist in nature, but we manipulated the nucleus inside an atom and opened up a Pandora’s box, so we should have prepared for risks and taken measures to respond. That is what is called the scientific spirit, I think. That’s why I believe that it is nothing but an excuse to define the Fukushima nuclear accident as something “unexpected.” It is a man-made, not a natural, disaster.
Elite and Cover-up Culture
HIRANO: What about the prevalence of cover-ups? What do you think of this tendency among elites in Japanese society?
MURAKAMI: This has something to do with the widely shared elite mentality. They honor self-sacrifice for the “greater good” or “common good,” which includes sacrificing your own life. You see it from how military officers acted and treated people during pre-war and wartime Japan. They didn’t hesitate to sacrifice citizens’ and soldiers’ lives in the name of the Emperor and in defense of our country. It is also true that they were driven to act this way for self-protection. I wonder how many citizens have been abandoned in the past.
There were Japanese civilian settlers who the Japanese government dispatched to what was then Manchuria. In the end, many of them, including children, were abandoned after the war. The Japanese Army heard about the Soviet Red Army crossing the Manchurian border, but did not let the settlers know about it. The Japanese Army rapidly retreated to the capital, Shinkyo (today’s Changchun), leaving the settlers behind. Millions of Japanese civilians were abandoned.
In fact, things like that happened not only in Manchuria but also on Saipan where Japanese civilians, who had lived on the island, were forced to fight against American soldiers. Worse than that was the battle of Okinawa. The Japanese military used civilians in Okinawa as a shield for the defense of the mainland and sacrificed their lives. Then it launched preparations for the final decisive battle, where the one hundred million people of the Japanese empire were expected to fight as one. For Japan’s leaders it was more important to not lose face before their superiors, as well as to protect the emperor, than to protect hundreds and hundreds of thousands of lives. This explains the reality of Japanese elites.
As for Fukushima, they tried to hide information from residents in Fukushima. Elites from the Fukushima Prefectural Government did the same thing. They did not hesitate to put residents in danger in order to protect their organization. We see such people in big corporations as well.
HIRANO: I see. The commitment to the greater good that Japanese elites value means, in the end, abandoning or discarding citizens. They are also protecting themselves.
MURAKAMI: Sure, their only purpose is to protect themselves including their social status and their organization. You surely will be kicked out if you dare to question them or even mention that they might be risking people’s lives. If you were to speak up, you would need to prepare for the consequences. We can say the same thing about the nuclear industry in Japan. A pyramid of power has been established in which graduates of Tokyo University reign at the top. All they care about is how they are treated in the organization and society, just as government officials do.
Constitution Matters
HIRANO: Let me ask you about the Constitution, in particular your view of the importance of individual freedom and human dignity. The Abe administration has been questioning its value and validity. And I think this issue is deeply interconnected with the way the administration deals with the disasters caused by the Fukushima power plant explosions.
MURAKAMI: During our education, we learned about the Constitution superficially. Freedom of speech or academic freedom was an object to memorize. But understanding it from a historical perspective is crucial. For example, Articles 31 to 40 explicitly forbid abuse by the police and state authorities. We need to think about why these articles were written so explicitly. It is because there had been a series of laws designed to suppress dissent in pre-war Japan, such as the Public Order and Police Law of 1900 and the Public Security Preservation Law of 1925. Under these laws, human rights were suppressed and brutally crushed by the full power of authority.
That’s the background of how criminal justice has been established in the Constitution, and that’s the reason why the Constitution describes each article in such detail. For example, Article 33 states that no one shall be apprehended without an arrest warrant issued by a competent judicial officer. Article 35 includes the right of protection against unusual searches and seizures, and the right to remain silent is guaranteed by Article 38.
I also realized the importance of Article 13 while holding public office and dealing with social welfare policies and services. It states that all people shall be respected as individuals. As you know, the Liberal Democratic Party has criticized individualism, saying that it has introduced the idea of selfishness to Japanese society and families and destroyed unity, but I realized while I was in office how crucial it is to look at every single person individually for purposes of social welfare and services. Recently I came across an article written by the late Hisada Eisei. He was a Constitutional scholar at Hokkaido University of Education who was deployed to Luzon in the Philippines during World War II, although he tried to flee the battlefield and never engaged in combat. In his book he describes how emotional he became when he saw Article 9 aboard the repatriation ship, and he claims that Article 13 is the fundamental principle of the Japanese Constitution: respect for human dignity.11
HIRANO: You have pointed out in your writings that Abe pushes his various policies by taking advantage of the criticism of individualism. He also often talks about his new defense and foreign policy doctrine, what he calls “proactive pacifism,” claiming that it will enable Japan to play an assertive role in promoting regional stability as an active contributor to peace and will bring more protection to individual rights and serve the nation in the long run.
What he is actually saying, however, is that individuals or his interpretation of individualism should be sacrificed for the interest of the nation. The nation or society comes before people. That’s what pacifism means to him. You are taking a diametrically opposite stance trying to understand what individualism really means, aren’t you?
MURAKAMI: That’s exactly right. If the nation does not exist, Abe claims, you will lose your life and freedom. What I believe is that individuals come first before the nation. When the nation or the government comes first, it will seize absolute power to control our lives as the wartime military has very well demonstrated. I argue that the nation should be built based on the principle of basic human rights, such as individual freedom and dignity. Abe speaks as if all of Japan’s neighboring nations are going to attack us. What he is trying to accomplish is the creation of a climate of fear.
HIRANO: Yes, by purposely stirring up nationalistic sentiment against China and Korea.
MURAKAMI: Exactly.
HIRANO: The Liberal Democratic Party has benefited greatly from tensions and disputes they provoke.
MURAKAMI: Although Abe said that he was open to starting a dialogue with China about the Senkaku islands, he did not take any actions to negotiate when Chinese patrol ships entered waters near the islands.
HIRANO: He made it clear that for Japan the question of ownership was not open to negotiation.
MURAKAMI: He has often said that we need to “bring back Japan” or “depart from the postwar regime”, but he uses these slogans to justify his policies. That is why he does not want to negotiate. He does not visit, nor does he send anyone to have a talk with China’s Coast Guard to prevent further accidents. As we know, Abe and his administration’s objectives have been to revise the Constitution and to over turn the postwar regime. In order to accomplish these goals, he refuses to negotiate.
Democracy in Crisis
HIRANO: What do you think about democracy in Japan? You mentioned to me on other occasions that you have some hope for Japanese young people, but it seems to me that the current situation is far from being optimistic. I have to wonder how postwar democracy has been functioning in this country. Observing the situation Japanese society is facing right now, especially after the Fukushima disaster, I am not quite sure how deeply postwar democracy has been established in this society.
MURAKAMI: I believe that one of the basic principles of democracy is the existence of the individual, but in Japan I feel that once each individual citizen is put into a big group, the individual is weakened or almost disappears. That’s why democracy cannot take root in this country. A lot of people think that democracy means deciding things by majority vote. But I don’t think so at all. Some people even say that once a political party wins by majority vote, citizens should not object to what the party decides. They believe that is what should be done in a democratic society. I believe that democracy means to listen to and respect each individual opinion, including opinions from the minority. The basic principle is individualism, and democracy does not exist as long as individual dignity is denied. I think the time has come again for us to be reminded how important it is to respect each individual’s dignity.
HIRANO: What do you think citizens in Japan should do when democracy as a political system is on the verge of crisis? When the Abe administration has been pushing to restart some of the nuclear reactors and public opinion seems to be going along with it, what do you think citizens can do? For example, would it be of any help to hold workshops or study groups to re-examine and discuss the Constitution? Or is direct action necessary?
MURAKAMI: I think the most important thing now is to have people who are aware of these problems begin to go over the Constitution again and re-examine its underlying spirit by questioning its origin and background. As I said earlier, unless we achieve profound understanding of Japanese history and the history of pre-war Japan and examine how the Constitution was created, we will not fully comprehend and appreciate what is written in it. Now that Japan is facing a crisis of democracy, I believe the active understanding of the Constitution may be able to save the situation. There are citizen movements, and we could say that people in the movements are new types of individuals, but I am worried that this could move in a dangerous direction, potentially leading to fascism. For example, recent growing anti-China and anti-Korea sentiments could lead in that direction. As the Nazis targeted the Jews, certain groups of people become a target. This is one of the characteristics of totalitarianism or fascism. I often hear the term, populism, but I find it alarming. People find a target inside the country, like the permanent ethnic Korean residents of Japan (Zainichi). Zaitokukai’s12 hate speech and internet right-wingers are a case in point. This is exactly the same thing that the Nazis did to Jews. When I visited Europe recently, I learned that the Swedish Parliament has far-right, far-left and Center parties, and in Europe this is called democracy.
HIRANO: Democracy ensures and respects diversity, disagreement, and spirit of civil dialogue. But populism propels anti-intellectualism and a culture of hatred.
MURAKAMI: In the recent political climate, there is a tendency to denounce the left or anyone who disagrees with one’s own point of view. By using the word leftist blindly, people are encouraging hate speech.
HIRANO: I agree. They are normalizing racism and discrimination. They categorize everything and everyone that is inconvenient or stands in their way as “leftist” or “traitor.” They even come up with a conspiracy theory, namely that leftists and traitors are working with China and South and North Korea to debase and weaken Japan. As you know, fascism functions well by targeting both internal and external enemies.
MURAKAMI: Exactly.
HIRANO: From what I’ve gathered, you are saying that the problem Japanese society has been facing since 3.11 results from the fact that it has not reflected on or deeply engaged with democratic values and thus has not established a firm basis for democratic practice. And the ongoing Fukushima crisis can be effectively dealt with only if people in Japan make a conscious choice of upholding the values of individual freedom and human dignity and decency as well as prioritizing the quality of life over economistic values and monetary gains.
MURAKAMI: Thank you for summing up so nicely.
HIRANO: Lastly, what do you think of the significance of Tōkaimura, the nation’s nuclear birthplace, becoming a leader of the anti-nuclear movement? Do you think there are certain messages that only Tōkaimura could disseminate to the world?
MURAKAMI: Tōkaimura has been made to play the role of a vanguard and a show window to promote nuclear power in Japan. It has also been carrying characteristics of living under nuclear colonialism. Tōkaimura’s history has aligned with the history of the promotion of nuclear development in Japan. Over the years, the Japan Atomic Energy Research Institute has played a hugely important role, but economically and financially, the Japan Nuclear Cycle Development Institute and Japan Atomic Power Company played a greater role.
It is true that Tōkaimura has been proud of being Japan’s nuclear power hub and being named the “Nuclear Center” or “Mecca of Nuclear Power.” As a result, it is possible to do everything in Tōkaimura from nuclear fuel fabrication, power generation and fuel processing. In the process, everything, including nuclear waste management, of course, was imposed on Tōkaimura.
On the other hand, it is also true that Tōkaimura used to be an impoverished village without even a brewery of sake, miso or soy sauce until the nuclear power plants and related facilities moved in. Therefore, the consciousness that all of the development and prosperity that the town has enjoyed since the 1960s is due to the nuclear power industry still exists strongly among residents.
Farmers were given employment at a nuclear facility, and merchants got contracts with the industry and no longer had to work hard to prosper. Also, cash flowed into the village from the sale of land to accommodate employees from Hitachi-related companies.
In this way, Tōkaimura gradually established an ethos and system within the administration and city council that would accept anything from government and industry without hesitation. The village has become an impregnable fortress and an incredibly cozy place for the promotion of nuclear energy. However, the JCO criticality accident came as a sort of rude awakening. This is a country that lacks the ability to keep nuclear power plants; therefore we should immediately follow Germany’s path of total abolition of nuclear power.
The Japanese government under Abe has been pushing to restore the previous energy policy that prevailed before the Fukushima nuclear accident. They say that the government will take full responsibility, but our government has no ability to do so. That’s the reality of this country. We must wake up and realize how senseless it is to rely on nuclear power that would result in loss of control and lead to a major disaster if something goes wrong even once.

Risk of hydrogen explosion from waste storage tanks At Fukushima Daiichi Nuclear Plant
Filter waste containers stored at Fukushima Daiichi
Tepco released documents on Friday detailing in depth the analysis of the stored HIC (high impact container) containers at the disaster site. Radioactive water had been found puddling up in the lip of the plastic and steel containers a few months ago. The end result is that the highly radioactive sludge in the containers is generating hydrogen gas. The sludge in these containers can be as high as 3 Sv/hour – 9 Sv.hour just for a single type of isotope. Container W6 was found to have concentrations high enough to cause an explosion of it encountered a spark or flame.
It said no radioactive water was found to have escaped outside the concrete structures that encase the containers.
According to TEPCO, there were about 1,300 such containers at the plant as of May 20.
They store waste water from the ALPS (advanced liquid processing system) equipment that removes radioactive substances from contaminated water.
The containers, which are made of polyethylene, are 1.8 meters high and have diameters of 1.5 meters.
The first leak was discovered in a lid on April 2.
TEPCO began inspecting others to see if they had similar problems. Of the 278 it had examined by May 20, it found 26 had some sort of leak or were bleeding from their lids.
The operator said the leaks and bleeding were likely caused by hydrogen and other types of gases that resulted from the water’s exposure to high levels of radiation.
Such gases appear to have accumulated in sediment at the bottom of the containers, expanding the volume of the liquid.
An NRA official said the accumulating hydrogen poses a potential danger.
“If the concentration level is high, a spark caused by static electricity could cause a container to explode,” the official said.
Although all the lids of the containers were supposed to be fitted with pressure-release valves to allow gasses to escape, TEPCO’s survey found that one did not have the mechanism.
Further review of the delivery records for the containers showed there may be as many as 333 that are also defective, a TEPCO official said.

Japan still aims to start removing fuel debris from stricken reactors in 2021
Japan still aims to start removing fuel debris from stricken reactors in 2021
Japan still aims to start removing nuclear fuel debris at the three damaged reactors at Tokyo Electric Power Co.’s Fukushima No. 1 power plant in 2021, it was learned Thursday.
The schedule remained intact in a draft update to the government’s roadmap to the decommissioning of reactors 1, 2 and 3, all of which experienced fuel meltdowns during the nuclear disaster from March 2011. The draft was submitted to a meeting of a government task force on the matter.
But it looks inevitable that the government will review the schedule. The exaction location of the molten nuclear fuel in the reactors is still unknown and radiation levels in and around the reactors are very high.
In autumn last year, the government and Tepco discussed a delay of about five years in the start of work to remove the fuel debris from reactor 1.
But the draft said Japan will choose the method to remove the debris by the end of September 2018 and start taking out the molten fuel by the end of 2021. It is still unclear which reactor Japan will choose for the first removal work.
Meanwhile, the government is reviewing the schedule for removing spent fuel at storage pools at the three reactors.
Removal work has been slated to begin for reactor 3 by the end of this September. But the work will likely be delayed because radiation levels remain high and operations to remove rubble from the damaged building have not progressed as planned.

The Nuclear Regulation Authority raised the maximum radiation exposure limit for nuclear workers in emergencies to 250 millisieverts
The Nuclear Regulation Authority decided Wednesday to raise the maximum radiation exposure limit for nuclear workers in emergencies to 250 millisieverts from the current 100, starting from next April.
Following the 2011 disaster at Tokyo Electric Power Co.’s Fukushima No. 1 nuclear complex, the maximum limit of cumulative exposure was raised to 250 millisieverts as an emergency measure for workers at the plant, but was lowered back to the previous limit of 100 in December 2011.
In light of the Fukushima meltdowns, the regulator had been considering raising the limit in the event of another disaster as Japan gets closer to reactivating some of its reactors, which remain offline amid heightened safety concerns.
Shunichi Tanaka, the NRA’s chairman, told a news conference that the current limit could be an obstacle in containing a crisis in the future, and the revision, which will entail a legal amendment, is “a step forward” in addressing the issue.
The regulator said it believes raising the limit to 250 millisieverts is appropriate based on overseas standards and scientific studies.

Video shot by robot inside damaged reactor May 16, 2015
The operator of the Fukushima Daiichi nuclear power plant on Friday released hundreds of hours of video footage showing the inside of the containment vessel of one reactor.
The footage was shot in April by 2 remote-controlled robots sent inside the No. 1 reactor’s vessel where radiation levels are very high.
Footage first captured shows fallen rubble in front of the robot.
The probe’s camera also captured what might be lead sheets that fell when meltdown occurred. Rubble can be seen piling up around them. All this testifies to the severity of the accident.
Meanwhile, no major damage was found in areas near the route leading to the bottom of the containment vessel.
Tokyo Electric Power Company plans to carry out further searches by sending robots to the lower levels of the vessel to look for nuclear fuel that melted down.
It also plans to send them into the containment vessel of the No. 2 reactor as early as August.
A survey using robots at the No. 3 reactor is expected to start as early as autumn this year.
The operator’s effort using robots to look into the reactor vessels will go into full swing in preparation for removing nuclear fuel. That should be the most difficult part of the work in the reactors’ decommissioning.
