Respite for Japan as radioactive Fukushima water accumulation slows

Aug 12, 2022
Tanks containing treated water at the crippled Fukushima nuclear power plant are likely to reach capacity around the fall of 2023, later than the initially predicted spring of next year, as the pace of the accumulation of radioactive water slowed in fiscal 2021.
The slowdown, based on an estimate by operator Tokyo Electric Power Company Holdings Inc., gives some breathing space to Prime Minister Fumio Kishida’s government if any roadblocks are thrown up in the plan to discharge the treated water into the sea starting around spring next year.
China and South Korea as well as local fishing communities that fear reputational damage to their products remain concerned and have expressed opposition to the plan.
About 1.30 million tons of treated water has accumulated at the Fukushima Daiichi plant following the 2011 nuclear disaster, and it is inching closer to the capacity of 1.37 million tons.
The water became contaminated after being pumped in to cool melted reactor fuel at the plant and has been accumulating at the complex, also mixing with rainwater and groundwater.
According to the plan, the water — treated through an advanced liquid processing system, or ALPS, that removes radionuclides except for tritium — will be released 1-kilometer off the Pacific coast of the plant through an underwater pipe.
The International Atomic Energy Agency has been conducting safety reviews of the discharge plan and Director General Rafael Grossi says the U.N. nuclear watchdog will support Japan before, during and after the release of the water, based on science.
An IAEA task force, established last year, is made up of independent and highly regarded experts with diverse technical backgrounds from various countries including China and South Korea.
Japan’s new industry minister Yasutoshi Nishimura says the government and TEPCO will go ahead with the discharge plan around the spring of 2023 and stresses the two parties will strengthen communication with local residents and fishermen, as well as neighboring countries, to win their understanding.
Beijing and Seoul are among the 12 countries and regions that still have restrictions on food imports from Japan imposed in the wake of the massive earthquake and tsunami triggered nuclear meltdowns at the Fukushima plant in March 2011.
“We will improve our communication methods so we can convey information backed by scientific evidence to people both at home and abroad more effectively,” Nishimura said after taking up the current post in a Cabinet reshuffle Wednesday.
Kishida instructed Nishimura to focus on the planned discharge of ALPS-treated water that will be diluted with seawater to one-40th of the maximum concentration of tritium permitted under Japanese regulations, according to the chief of the Ministry of Economy, Trade and Industry.
The level is lower than the World Health Organization’s recommended maximum tritium limit for drinking water.
TEPCO will cap the total amount of tritium to be released into the sea as well.
Meanwhile, the Kishida government has decided to set up a 30 billion yen ($227 million) fund to support the fisheries industry and said it will buy seafood if demand dries up due to harmful rumors.
Fishing along the coast of Fukushima Prefecture, known for high-quality seafood, has been recovering from the reputational damage caused by the nuclear accident but the catch volume in 2021 was only about 5,000 tons, or about 20 percent of 2010 levels.
Construction of discharge facilities at the Fukushima plant started in August, while work to slow the infiltration of rain and groundwater was also conducted.
TEPCO said it was able to reduce the pace of accumulation of contaminated water by fixing the roof of a reactor building and cementing soil slopes around the facilities, among other measures, to prevent rainwater penetration.
The volume of radioactive water decreased some 20 tons a day from a year earlier to about 130 tons per day in fiscal 2021, according to the ministry.
The projected timeline to reach the tank capacity has been calculated based on the assumption that about 140 tons of contaminated water will be generated per day, according to METI.
However, storage tanks could still reach their capacity around the summer of next year if heavy precipitation or some unexpected events occur, the ministry said.
As part of preparations for the planned discharge, the Environment Ministry has started measuring tritium concentration at 30 locations on the surface of the sea and seabed around the Fukushima plant, four times a year.
Similarly, the Nuclear Regulation Authority has increased the number of locations it monitors tritium levels by eight to 20. The Fisheries Agency has started measuring tritium concentration in marine products caught along the Pacific coast stretching from Hokkaido to Chiba Prefecture.
Given that it is expected to take several decades to complete the release of treated water, NRA and METI officials urged TEPCO to further curb the generation of contaminated water at the plant.
“We want TEPCO to step up efforts so as to lower the volume of the daily generation of contaminated water to about 100 tons or lower by the end of 2025,” a METI official said.
More Cases of Stomach Cancer in Fukushima Prefecture.
Stomach cancer, which has been confirmed in Fukushima Prefecture for eight consecutive years, was also found to be more common among A-bomb survivors in Hiroshima and Nagasaki

Stomach Cancer Incidence Rate Rises among Women in Fukushima Prefecture

On May 27, 2019 national cancer registry data was released on the government statistics website e-Stat.
Following up on my article that appeared on this website on August 26, 2011 (“Stomach Cancer in Fukushima Prefecture”: Confirmation of the 7th consecutive year of “high incidence of stomach cancer” — Should the Fukushima Daiichi Nuclear Power Plant accident no longer be regarded as a “major pollution incident”? (–) (https://level7online.jp/?p=4608), we compared the “National Incidence Rate of Stomach Cancer by Age Group” with the same rate in Fukushima Prefecture, based on the published data for 19 years.
Table 1 shows the results. Various age groups for both men and women exceeded the national average. In particular, in 2007, there were many age groups among women that exceeded the national average. Some of the age groups are double the national average (40-44 years).
On the other hand, only three age groups (0-4, 20-24, and 25-29) were below the national average. Therefore, it is necessary to pay attention to the “increase in the incidence rate of stomach cancer among women in Fukushima Prefecture” over the past few years.
Next, we conducted a comparison with the actual number of cases of gastric cancer in Fukushima Prefecture, assuming that the same rate of gastric cancer is occurring in Fukushima Prefecture as in the rest of Japan. This is a method to calculate the “standardized incidence ratio” (SIR) using epidemiological methods. The national average is set at 100, and if it is higher than the national average, it means above the national average, and if it is lower than the national average, it means below the national average.
The following is the result of the calculation of SIR for the period from 2008 to 2007 for stomach cancer in Fukushima Prefecture.
Stomach cancer] Number of cases in Fukushima Prefecture SIR
Male: 1279 88.3 in 2008
Male in 2009: 1366 94.1
10-year male: 1500 101.1
11-year male: 1391 92.2
12-year male: 1672 110.6
13-year male, 1659 110.9
14-year male, 1711 119.3
15-year male, 1654 116.6
16-year male, 1758 116.3
17-year man 1737 120.0
18years male, 1685 120.0
19-year man 1743 126.9
2008 female 602 86.6
2009 female 640 94.2
10-year female 700 100.9
11year female 736 100.9
12-year woman 774 109.2
13-year girl 767 109.9
14-year girl 729 109.0
15-year girl 769 120.3
16-year girl 957 139.4
17-year girl 778 119.6
18-year girl 744 118.4
19-year female: 817 131.8
The National Cancer Center considers a prefecture to have a “high cancer incidence rate” when the SIR exceeds 110. The SIR for stomach cancer in Fukushima Prefecture has been higher than the national average for both men and women since 2000, and the latest data for 2007 shows that the SIR for men was 12.6.9 and for women 131.8. The latest data from 2007 shows an abnormally high SIR of 12.6.9 for men and 131.8 for women.
We then tried to find the “95% confidence interval” for this SIR. This is one of the validation tasks in epidemiology, where the upper limit (or more precisely, the “upper limit of the estimate”) and the lower limit (or the “lower limit of the estimate”) of each SIR are calculated, and if the lower limit is 10 If the lower limit exceeds 0, it means that the increase is not merely increasing, but is a “statistically significant multiple occurrence” that cannot be considered as a coincidence in terms of probability.
The results are shown in [Table 2]. In Fukushima Prefecture, the incidence of stomach cancer in both men and women has been “significantly high” for eight consecutive years since 2000, and SIR has also been on the rise, showing no sign that the incidence of stomach cancer is slowing down. As is clear from the number of cases in Table 2, while the number of stomach cancer cases nationwide has continued to decline in recent years, the number of cases in Fukushima Prefecture, on the contrary, has increased.
Incidentally, the Centers for Disease Control and Prevention (CDC) in the U.S. published a report on the minimum incubation period for cancer, Minimum The CDC (Centers for Disease Control and Prevention) has published a report on the minimum latency of cancer, Minimum Latency & Types or Categories of Cancer (hereinafter referred to as the “CDC Report”). The CDC report on the “Minimum Latency & Types or Categories of Cancer” (hereinafter referred to as “CDC Report”) lists, in order from shortest to longest, the following
Leukemia, malignant lymphoma: 0.4 years (146 days)
Childhood cancer (including pediatric thyroid cancer): 1 year
Adult thyroid cancer: 2.5 years
All solid cancers including lung cancer: 4 years
Mesothelioma] 11 years
and so on [Table 3]. According to this CDC report, the shortest latency period for stomach cancer is “4 years.
In other words, 12,642 Fukushima Prefecture residents who have contracted stomach cancer since 2015, four years after the occurrence of the TEPCO Fukushima Daiichi nuclear power plant accident, include 12,642 people from the same nuclear power plant. It is possible that some of the 12,642 Fukushima residents who have developed stomach cancer since 2015, four years after the accident at TEPCO’s Fukushima Daiichi nuclear power plant, developed the disease as a result of exposure to toxic substances released by the accident.
Prior to the Fukushima Daiichi nuclear accident, until 2010, stomach cancer SIRs among Fukushima residents were equal to or lower than the national average. The “excess” of the SIRs was the “excess” of the national average. It is eagerly awaited that the correlation and causal relationship between the accident and carcinogenesis will be verified from the viewpoint that the “excess” number of stomach cancer patients may include victims of the nuclear power plant accident.
Both the number of thyroid cancer cases and the incidence rate of thyroid cancer in males have increased.
Next, we will examine thyroid cancer, which is a concern because of its high incidence among young people, and the CDC report indicates that the minimum incubation period is 2.5 years for adults and 1 year for children. 1 year for children.
The incidence rates of thyroid cancer by age group and the number of cases by age group calculated from these rates are shown in Tables 4 and 5. In 2019, eight years after the Fukushima Daiichi Nuclear Power Plant accident, thyroid cancer was still confirmed in young people.
Among females, 2 were confirmed in the 10-14 age group, 8 in the 15-19 age group, 5 in the 20-24 age group, and 6 in the 25-29 age group. The total for all age groups was 199, meaning that patients who were under the age of 20 at the time of the accident in 2011 accounted for about 8% of the total at the lowest estimate and about 11% at the highest estimate [Table 5].
On the other hand, 4 males were identified in the 10-14 age group, 6 in the 15-19 age group, 1 in the 20-24 age group, and 2 in the 25-29 age group. The total number of patients in all age groups is 76, which means that patients who were under the age of 20 at the time of the accident in 2011 accounted for about 14% of the total at the lowest estimate and about 17% at the highest estimate [Table 5].
The SIR and its “95% confidence interval” for thyroid cancer are shown in Table 6. In both cases, the minimum incubation period for thyroid cancer, 2.5 years, had elapsed since the accident at the Fukushima Daiichi Nuclear Power Plant in 2011.
In the latest 19-year period, the number of cases and incidence rate of thyroid cancer in Fukushima Prefecture increased for males. Both the number of cases and incidence rate decreased for females.
Significant “high incidence” continues for gall bladder and bile duct cancer.
No trend of increased incidence was observed for malignant lymphoma and leukemia ([Table 7] and Table 8]).
The most recent 2019 data also showed a continued abnormality in gall bladder and bile duct cancer, which is classified as a “solid cancer” according to the CDC report, with a minimum latency period of “4 years” (Table 8). The minimum latency period is 4 years.
Significant incidence” of gall bladder and bile duct cancer was observed in men in 2010 and in women in 2009, before the nuclear accident. After 2016, when the minimum incubation period of “4 years” has passed, “significantly high incidence” was confirmed in both men and women. The incidence was “high” for four consecutive years for males and six consecutive years for females ([Table 9]).
Prostate cancer, which was found to be “significantly more frequent” for three consecutive years from 2004 to 2006, had its “more frequent” status eliminated in the latest 2019 data. Nevertheless, the SIR remains above the national average, so continued attention should be paid to this issue ([Table 10]).
Finally, regarding ovarian cancer. The minimum incubation period is “4 years” (Table 11). Although “significantly more cases” were observed in 2013 and 2014 before the minimum incubation period, the SIR has been below the national average since then. However, the latest data for 2019 shows that SIR exceeded the national average for the first time in five years, and the number of cases in the prefecture continues to increase slightly, so it is important to pay attention to the data.
Stomach cancer was also on the rise among A-bomb survivors in Hiroshima and Nagasaki
Toshihide Tsuda, a professor at the Graduate School of Okayama University who specializes in epidemiology and causal inference, took a look at these data. Professor Tsuda said.
The situation is more severe than we had expected, and it has exceeded our projections by quite a bit. Not only thyroid cancer, which has already shown a clear increase, but also other cancers that are now on the rise are cancers that are also noticeably on the rise in the data on A-bomb survivors in Hiroshima and Nagasaki. I feel that it is necessary to make appropriate preparations, quickly formulate countermeasures and enhanced risk communication, and discuss how to respond to the situation. I suspect that the actual radiation exposure was considerably higher than what has been publicized.”
The Ministry of the Environment’s “Uniform Basic Data on Radiation Health Effects, etc.” (FY 2008 edition) states
The Ministry of the Environment’s “Uniform Basic Data on Radiation Health Effects” (FY 2008 edition) states, “In adults, the organs most likely to develop cancer due to radiation exposure are the bone marrow, colon, breast, lung, and stomach.
(Figure below). In other words, an increase in stomach cancer has been observed among A-bomb survivors.

To be sure, we also examined breast cancer and lung cancer, which are considered to be more common among A-bomb survivors, and found no “significant increase” in the Fukushima Prefecture data through 2007. However, a slight upward trend was observed for breast cancer in males, a rare cancer, since 2004 (5 cases in 2002, 7 cases in 2003, 10 cases in 2004, 11 cases in 2005, 10 cases in 2006, and 7 cases in 2007). The number of cases of breast cancer in the United States is also reported.
The number of people who have been living in the area since the last year (October 2021) is still very high.
Kenichi Hasegawa (68 years old), a former dairy farmer in Iitate Village, who passed away from thyroid cancer last October (2021), revealed in February 2008 that “a number of people in the village have contracted stomach cancer and died one after another,” and said the following.
People in their late fifties and sixties, younger than me, are dying. Most of them have cancer. This was not the case in Iitate Village before the nuclear accident.
They died at the same age as us, so it is even more memorable. And it is not long after the cancer is found that it gets worse and worse and they pass away.
If you get cancer when you are 80 or 90 years old, you may think that it can’t be helped and that you have fulfilled your destiny, but that is not the case if you are in your 60s,” he said.
Mr. Hasegawa himself had less than a year from the time he found out he had cancer to the time of his death.
In November 2002, Mr. Hasegawa and about 2,800 other Iitate villagers filed a claim for compensation from TEPCO for health concerns caused by high initial radiation exposure due to the delay in evacuation. In November 2002, they filed an application for alternative dispute resolution (ADR) with the Center for the Resolution of Nuclear Damage Disputes. The “fears” of that time are now beginning to become a reality.
Some scientists and journalists, by the way, have been reporting on the UN Scientific Committee on the Effects of Atomic Radiation (UNSCEAR) without any check of the data from the National Cancer Registry. (UNSCEAR).
“It is unlikely that there are any future health effects directly attributable to radiation exposure.
There are those who stubbornly try to deny the occurrence of cancer due to the nuclear accident, waving the UNSCEAR report as if it were a “banner”. However, the UNSCEAR report is not based on actual measurements due to the fact that Fukushima and other prefectures prevented the survey of radiation doses immediately after the accident. The UNSCEAR report, however, is not a fact in itself.
If you call yourself a scientist or a journalist and really want to deny the occurrence of cancer due to the nuclear accident, you should verify it with your own hands using the National Cancer Registry data, which is the “facts themselves,” instead of relying only on the estimated reports made by others. The national cancer registry data is also data for this purpose.

Japan extremely selfish to insist on discharging nuclear wastewater into sea
August 8, 2022
TOKYO, Aug. 10 (Xinhua) — Japan’s Tokyo Electric Power Company Holdings Inc. (TEPCO) has recently started construction of facilities that will discharge radioactive wastewater from the crippled Fukushima Daiichi nuclear power plant into the sea, taking another step in its plan to release nuclear-contaminated water.
The Japanese government’s drive to push through a long-term plan to release wastewater into the Pacific Ocean starting in the spring of 2023, despite domestic and international opposition, is extremely selfish, analysts say.
SELFISHNESS
Struck by a magnitude-9.0 earthquake and ensuing tsunami that hit Japan’s northeast on March 11, 2011, the No. 1-3 reactors at the Fukushima Daiichi nuclear plant suffered core meltdowns, resulting in a level-7 nuclear accident, the highest on the International Nuclear and Radiological Event Scale.
The plant has been generating a massive amount of radiation-tainted water since the accident happened as it needs water to cool the reactors. With groundwater and rainwater also flowing in, about 1.3 million tons of contaminated water are now stored at the nuclear plant and are still increasing at a rate of 140 tons a day.
TEPCO claimed that the water storage tank’s current storage capacity of 1.37 million tons will run out this autumn and the plant has no more space for new water storage tanks to be constructed, so it has to release the contaminated water into the sea after filtering, purifying and diluting it.
In response to TEPCO’s claims, Japanese environmental groups pointed out that much of the land near the plant has been left idle due to nuclear leakage and could be used to construct additional water storage tanks.
However, the Japanese government and TEPCO rejected the idea, citing the need for a large amount of time for communication and coordination as well as a lot more work.
Environmentalists say it is not that the option is infeasible, it is because the Japanese government and TEPCO do not want to do it, as they put their own interests first.
A panel of experts organized by Japan’s Ministry of Economy, Trade and Industry had proposed five options when considering how to deal with the contaminated water.
Among them, the Japanese government said the options of discharging the water into the sea and vapor release were two “most practical solutions” and it finally chose the former one, which “takes the shortest time and costs the least,” passing on the risk to the whole world.
BROKEN CREDIT
Contaminated water generated at TEPCO’s Fukushima Daiichi nuclear power plant contains tritium, cesium, strontium and other radioactive materials. The Japanese government and TEPCO said they would use the Advanced Liquid Processing System (ALPS), a multi-nuclide removal equipment, to reduce the concentrations of 62 types of radioactive substances, with the exception of tritium, which is hard to remove by purification and will remain in the treated water.
TEPCO believes that tritium normally remains in the wastewater at ordinary nuclear power stations, therefore it is safe to discharge tritium-contaminated water.
Experts say TEPCO is trying to confuse the concept of the wastewater that meets international standards during normal operation of nuclear power plants with that of the complex nuclear-contaminated water produced after the core meltdowns at the wrecked Fukushima power plant.
The actual results of ALPS are not as ideal as TEPCO claims. Japanese media have found that in addition to tritium, there are a variety of radioactive substances in the Fukushima nuclear wastewater that exceed the standard. TEPCO has also admitted that about 70 percent of the water treated by ALPS contains radionuclides other than tritium at the concentration which exceeds legally required standards and requires filtration again.
Also the reliability of ALPS itself is questionable. According to a report by Japan’s Asahi Shimbun in September 2021, 24 of the 25 filters used by ALPS to absorb radioactive substances were damaged, and the damage occurred two years ago, but TEPCO did not deal with it in time.
The Korean Federation for Environmental Movements, a South Korean civic environmental organization, said that TEPCO claimed to have the ability to reduce the concentration of 62 radioactive substances excluding tritium before the discharge of the contaminated water, but this is by no means the truth. The organization warned that it is hard to clean the sea water once it is polluted.
From the cover-up of the meltdown at the beginning of the Fukushima disaster to the bowing and apologizing for underreporting for more than a decade, TEPCO has left so many stains on its credibility that its nuclear credit has long since gone busted.
OPPOSITION FROM ALL SIDES
The willful push by the Japanese government and TEPCO to release wastewater into the sea has triggered strong opposition from both within Japan and its neighboring countries. Last Wednesday, a local civic group organized a protest outside the government house of Fukushima Prefecture to show their opposition to the plan.
After TEPCO announced last Thursday the start of the construction of facilities for releasing radioactive wastewater into the sea, a Japanese environmental organization issued a statement on the same day, pointing out that the Japanese government and TEPCO had made written commitments on the matter saying “without the understanding of relevant personnel, no actions will be taken.” However, the government still decided in April last year to release the nuclear-contaminated water into the sea without seeking advice from relevant parties to make it a fait accompli.
On July 22, the Nuclear Regulation Authority of Japan officially endorsed TEPCO’s nuclear-contaminated water discharge plan.
Responding to this, Masanobu Sakamoto, president of the National Fisheries Cooperative Federation of Japan, said the plan has not gained the understanding of the public and the fishery industry and that the federation’s firm opposition to the discharge had not changed at all.
Greenpeace Seoul Office said that the danger of discharging nuclear-contaminated water into the sea is obvious. The Japanese government’s decision to discharge the contaminated water into the sea when there are alternatives such as long-term storage violates the precautionary principle recognized by the international community.

Japan’s unilateral decision of dumping nuclear-contaminated water into ocean not responsible: Chinese ambassador for disarmament affairs
Aug 09, 2022
Japan’s dumping of Fukushima nuclear-contaminated water into the ocean will have influence on the ocean environment, security of food and people’s health, and Japan made such unilateral decision without having full negotiation with neighboring countries or international organizations, which is irresponsible and immoral, Li Song, Chinese ambassador for disarmament affairs, said Monday at the Tenth Review Conference of the Parties to the Treaty on the Non-Proliferation of Nuclear Weapons, expressing strong concerns over the related issues.
Japan’s unilateral decision to dump Fukushima nuclear-contaminated water into the ocean is made purely out of concerns for its own economic cost, and it has neither resorted to all possible ways to handle it, nor had full negotiations with neighboring countries. Such selfish move is to transfer the risk to the international community. People in Japan, China, South Korea, Russia and Pacific island countries all expressed their concerns, Li said.
Japanese regulators have approved the plan of dumping Fukushima’s nuclear-contaminated water into the sea, which has caused safety concerns in the international community and neighboring countries.
Li pointed out that the international community has paid great attention on issues of the legitimacy of Japan’s plan of dumping the water, the credibility over the data, efficiency of the decontamination equipment, and the influence on the environment.
The International Atomic Energy Agency has not reached a final conclusion on the assessment on Japan’s plan, but has given Japan many improvement suggestions. But regrettably, Japan has purposely neglected it and kept pushing its plans. Such moves are not what a responsible country should take, Li said.
Dumping Fukushima’s nuclear-contaminated water into the ocean is not Japan’s own business and Japan should respond to the global concerns and go back to the track of communicating with parties of shared concerns. And it should stop forcibly pushing the dumping plan, Li said.
Japan should make sure handling the water in an open, transparent, scientific and safe manner, and take alternative plans and accept supervision of the International Atomic Energy Agency, said Li, noting that this is the touchstone to test whether Japan can effectively fulfill its responsibility.

Construction begins at Fukushima plant for water release

August 4, 2022
TOKYO (AP) — The construction of facilities needed for a planned release of treated radioactive wastewater into the sea next year from the damaged Fukushima nuclear power plant began Thursday despite opposition from the local fishing community.
Plant workers started construction of a pipeline to transport the wastewater from hillside storage tanks to a coastal facility before its planned release next year, according to the plant operator, Tokyo Electric Power Company Holdings.
The digging of an undersea tunnel was also to begin later Thursday.
Construction at the Fukushima Daiichi plant follows the Nuclear Regulation Authority’s formal approval last month of a detailed wastewater discharge plan that TEPCO submitted in December.
The government announced last year a decision to release the wastewater as a necessary step for the plant’s ongoing decommissioning.
A massive earthquake and tsunami in 2011 destroyed the Fukushima Daiichi plant’s cooling systems, causing triple meltdowns and the release of large amounts of radiation. Water that was used to cool the three damaged and highly radioactive reactor cores has since leaked into basements of the reactor buildings but was collected and stored in tanks.
TEPCO and government officials say the water will be further treated to levels far below releasable standards and that the environmental and health impacts will be negligible. Of more than 60 isotopes selected for treatment, all but one — tritium — will be reduced to meet safety standards, they say.
Local fishing communities and neighboring countries have raised concerns about potential health hazards from the radioactive wastewater and the reputation damage to local produce, and oppose the release.
Scientists say the impact of long-term, low-dose exposure to not only tritium but also other isotopes on the environment and humans are still unknown and that a release is premature.
The contaminated water is being stored in about 1,000 tanks that require much space in the plant complex. Officials say they must be removed so that facilities can be built for its decommissioning. The tanks are expected to reach their capacity of 1.37 million tons in autumn of 2023.
TEPCO said it plans to transport treated and releasable water through a pipeline from the tanks to a coastal pool, where it will be diluted with seawater and then sent through an undersea tunnel with an outlet about 1 kilometer (0.6 miles) away to minimize the impact on local fishing and the environment.
TEPCO and the government have obtained approval from the heads of the plant’s host towns, Futaba and Okuma, for the construction, but local residents and the fishing community remain opposed and could still delay the process. The current plan calls for a gradual release of treated water to begin next spring in a process that will take decades.
TEPCO said Wednesday that weather and sea conditions could delay a completion of the facility until summer 2023.
Japan has sought help from the International Atomic Energy Agency to ensure the water release meets international safety standards and reassure local fishing and other communities and neighboring countries, including China and South Korea, that have opposed the plan.
IAEA experts who visited the plant earlier this year said Japan was taking appropriate steps for the planned discharge.

Facility construction begins for Japan’s Fukushima nuclear wastewater release amid opposition

TOKYO, Aug. 5 (Xinhua) — The construction of facilities to release radioactive wastewater into the sea from the crippled Fukushima Daiichi nuclear power plant in northeastern Japan began Thursday despite opposition from the local community and neighboring countries.
Plant workers started construction of a pipeline to transport the wastewater from hillside storage tanks to a coastal facility before its planned release next year, according to the plant’s operator, Tokyo Electric Power Company Holdings Inc. (TEPCO).
On Tuesday, TEPCO has gained approval from Fukushima Governor Masao Uchibori and the mayors of Okuma and Futaba, which host the crisis-hit power plant, to start the construction, but serious concerns remain.
Local residents and the fishing community concerned about the impact on their fish catches and livelihoods and remain opposed to the plan, which calls for a gradual release of tons of treated water into the Pacific Ocean to begin next spring.

China has expressed its firm opposition to the plan as China’s Foreign Ministry Spokesperson Wang Wenbin said previously that it is extremely irresponsible for Japan to ignore the concerns and strong opposition from all parties.
“If Japan insists on putting its own interests above the public interest of the international community and insists on taking the dangerous step, it will surely pay the price for its irresponsible behavior and leave a stain in history,” Wang said.
The South Korean government has stated that it would take “best responsive measures internally and externally” under the principle that people’s health and security are of utmost importance.
A massive tsunami, triggered by an earthquake of 9.0 magnitude off Japan’s northeastern coast, struck TEPCO’s Fukushima Daiichi power plant in March 2011. TEPCO said that it is running out of storage tanks to hold water used to cool the melted-down cores.
The Japanese government decided in April 2021 that the contaminated water had to be released into the sea as the facility is fast running out of space to set up more storage tanks, which already number in the hundreds.

Fukushima Daiichi Nuclear Power Plant “Treated Water” Discharged TEPCO Announces Undersea Tunnel Construction to Begin in 4 Days “Already Started? Citizens were in a state of exasperation
August 3, 2022
TEPCO announced on August 3 that it will begin construction of an undersea tunnel and other facilities on August 4 to discharge contaminated water from the Fukushima Daiichi Nuclear Power Plant (Okuma and Futaba, Fukushima Prefecture) after purification and treatment. The company aims to begin discharging the water next spring, but if the offshore construction is delayed by weather conditions or other factors, the completion of the facilities may be delayed until next summer. However, there is strong opposition to the project, especially from those involved in the fishing industry, and it is unclear whether the facilities will actually be able to discharge the radioactive waste.

On the 2nd, the prefectural government and both towns in the area agreed to the construction work, and on the 4th, they will begin digging undersea tunnels and laying pipes to transfer treated water from the storage tanks. TEPCO is proceeding with some of the work outside the scope of the consent, and has finished digging the hole that will house the water storage tank that will lead to the undersea tunnel.
At the press conference, Junichi Matsumoto of TEPCO’s Fukushima Daiichi Decommissioning Promotion Company made it clear that “there is no doubt that we will comply with the document with fishermen,” regarding the written promise with the Fukushima Prefectural Fisheries Federation that no ocean discharge would take place unless understanding is obtained. However, he simply reiterated that he would “do his best to explain” how to gain their understanding.
When asked if TEPCO executives would brief fishermen before construction began, he replied, “We have no plans to do so. Meanwhile, Prime Minister Fumio Kishida met with Masanobu Sakamoto, chairman of the National Federation of Fishermen’s Cooperative Associations, on the same day. Regarding a large fund for the continuation of the fishing industry, he said, “We would like to obtain the fishermen’s understanding on how to use the fund after hearing their opinions.
According to TEPCO’s plan, the treated water, which is mainly tritium, will be diluted with a large amount of seawater to less than 1/40th of the national discharge standard, and then discharged through an undersea tunnel about 1 km offshore.
◆”Voices not being heard by the government,” citizens’ group protests.
On March 3, when TEPCO announced the start of construction of facilities to discharge treated water from the Fukushima Daiichi Nuclear Power Plant into the ocean, citizens’ groups in Fukushima Prefecture staged a protest in front of the prefectural government office, and the leaders of local governments where the plant is located asked the government to take thorough measures against harmful rumors.
On the afternoon of the 3rd, the co-chairman of the “Citizens’ Council” Oda, who heard about the plan to start construction on the following day, said, “What, it has already started? Chiyo Oda, 67, co-chairperson of the “Citizens’ Council” in Iwaki City, Fukushima Prefecture, was absolutely stunned. Construction began just two days after Fukushima Prefecture and the towns of Okuma and Futaba agreed to the work. She was concerned that the situation would become so dire that there would be no turning back.
In the morning of that day, the association held a banner in front of the prefectural office to protest. At a press conference held afterward, Mr. Oda said, “The plan is proceeding with the release of the waste. There are so many voices of opposition and concern, but the government is not receiving our voices? Kaoru Watanabe, 66, a resident of Date City in Fukushima Prefecture, expressed his concern, “I’m worried that they will push ahead with the construction work, create a fait accompli, and then push through with the discharge into the ocean.
Fukushima Governor Masao Uchibori, Okuma Mayor Jun Yoshida, and Futaba Mayor Shiro Izawa visited the Ministry of Economy, Trade and Industry and submitted a written request to METI Minister Koichi Hagiuda. Governor Uchibori told the press, “I hope that the government will work together to take the necessary measures (against harmful rumors, etc.) so that the efforts of the people of Fukushima Prefecture will not be undone by the release of the radioactive materials.

TEPCO Starts Construction of Fukushima Water Release Facilities
Get ready for a new wave… of radioactive wastewater!
ineptco’s tunnel will carry the enriched water a whole kilometer from the coast
August 4, 2022
Tokyo Electric Power Company Holdings Inc. on Thursday started the construction of facilities to release treated radioactive water into the ocean from its disaster-crippled nuclear plant in the northeastern Japan prefecture of Fukushima.
TEPCO aims to complete the construction work around next spring, although the company said the completion might be pushed back to around summer next year if the work at sea is delayed due to bad weather or other factors.
There are lingering concerns about negative rumors related to the planned release of the water, which contains tritium, a radioactive substance, into the ocean. Understanding from related local people would be essential for TEPCO to start the water release after the completion of the facilities.
TEPCO will construct an undersea tunnel necessary for releasing the treated water at a point 1 kilometer off the coast. Tanks and pipes will also be set up for stirring the treated water and checking whether radioactive substances other than tritium are below safety standards.
Also, the company will build a facility to dilute the treated water, after its levels of radioactive substances are measured, with seawater to lower the tritium concentration to less than one-40th of the level permitted under Japanese safety standards.
TEPCO gets the go-ahead for first phase of plan to discharge water
August 3, 2022
FUKUSHIMA–Local officials here gave the go-ahead to Tokyo Electric Power Co. to begin preparations to discharge tons of treated but still contaminated water from its stricken Fukushima No. 1 nuclear power plant into the Pacific Ocean.
Approval was given Aug. 2 by Fukushima Governor Masao Uchibori and the mayors of Okuma and Futaba, where the TEPCO plant is located, for the utility to begin work to dig a tunnel from the site and install the necessary equipment.
However, TEPCO still needs to gain the understanding of “interested parties” before any water can be released.
The plan has angered local fishermen concerned about their livelihoods and triggered alarm overseas as the water will still contain a radioactive element, tritium, which is a radioactive isotope of hydrogen, that cannot be removed with current technology.
Thousands of tons of contaminated water have accumulated at the plant that went into triple meltdown in the aftermath of the 2011 earthquake and tsunami disaster, and the facility is fast running out of space to set up more storage tanks.
Tetsu Nozaki, who heads the Fukushima prefectural federation of fisheries cooperatives, told reporters in late July that his organization remains steadfastly opposed to the release of the water into the ocean. Fishermen also are up in arms, fearing the move would only fuel further negative publicity over their fish hauls.
Uchibori and the mayors met Aug. 2 with Tomoaki Kobayakawa, the TEPCO president, and told him they had no issue with the safety of the equipment to be used.
Prior approval of any new equipment TEPCO plans to install at the Fukushima plant is required under a safety agreement the local governments signed with the utility.
Uchibori again pressed TEPCO officials to make an all-out effort to gain the understanding of interested parties so the water release plan can go ahead.
The Nuclear Regulation Authority in July approved TEPCO’s water release plan. Prior to that, Uchibori stated that any decision on approving the new equipment to be installed at the Fukushima plant would be made regardless of opposition among interested parties to the plan.
In August 2015, the government and TEPCO submitted a document to the prefectural fisheries cooperatives federation stating that no water would be treated and released into the ocean without the understanding of the interested parties.
Ironic for Tokyo to caution others on nuclear issue despite Fukushima plan

Aug 03, 2022
Japanese Prime Minister Fumio Kishida urged all nuclear countries to conduct themselves “responsibly” in non-proliferation efforts on Monday when he spoke at the Review Conference of the Parties to the Treaty on the Non-Proliferation of Nuclear Weapons (NPT) at the United Nations in New York.
The NPT Review Conference is held regularly to have discussions focused on the three pillars of nuclear disarmament, nuclear non-proliferation and peaceful uses of nuclear energy.
The issue of releasing nuclear contaminated water from the crippled Fukushima Daiichi nuclear power station is also on the agenda. In his speech, Kishida, who already foresaw related discussion unfavorable to Japan, was giving the runaround to avoid being criticized due to Japan’s extremely irresponsible plan to release contaminated water. In fact, the review conference will be between August 1-26, but Kishida is scheduled to return to Japan on August 2 after delivering his speech on the first day of the conference, at a time when specific discussion of issues on the agenda have not yet begun. No one will be able to find Kishida when the issue of releasing nuclear contaminated water is on the table.
Since its entry into force, the NPT as an international framework has guided various countries to use nuclear science and technology for peace and development. Peaceful use of nuclear energy is allowed, but it’s appalling that Japan decided to discharge nuclear contaminated water into the ocean. But how serious the consequences will be after the actual dump? It will be unpredictable and irreversible.
It’s ridiculous that Japan’s actions, which may have far-reaching impact on the world, have been “approved” and tolerated by the US. In contrast, the leakage of the Chernobyl nuclear power plant in the former Soviet Union is still strongly criticized by the US. This is undoubtedly a double standard. Wang Guangtao, an associated research fellow at the Center for Japanese Studies, Fudan University, believes that geographically speaking, although the US is also a Pacific country, judging from the flow direction and diffusion trajectory of ocean currents, nuclear contaminated water discharged by Japan will first affect Japan’s neighboring countries, not the US on the other side of the Pacific Ocean.
Japan is the only country that experienced the nuclear attack. The US has been reluctant to criticize Japan over the release of nuclear contaminated water because of the sense of guilt and its own dark history in terms of nuclear radiation.
Japan and the US maintain close communication based on the alliance, and the US is bound to side with its Asian ally, rather than listen to the opposition of neighboring countries such as China and South Korea. The possibility that the US and Japan may have reached a deal under the table cannot be ruled out, as Japan, an East Asian country, first informed the US when it decided to release the nuclear contaminated water into the sea. The report released by Japanese expert panel which calculated anticipated radiation dose to the locals after discharging all the water to the sea was soon endorsed by the International Atomic Energy Agency, in which the US is quite influential. This undoubtedly mirrors the hypocrisy of “rules-based international order” the US has vaunted.
Covered up by the US, Japan has been brazenly manipulating the nuclear issue. On the issue of nuclear safety, it is ultimately Japan that should be responsible for the health and safety of all humankind, rather than urging others to act “responsibly” when it’s on the verge of discharging nuclear contaminated water into the ocean.
Fukushima OKs facility construction for treated water release plan
August 2, 2022
Local authorities have approved the construction of an underwater tunnel and other facilities to release treated water from the crippled Fukushima Daiichi nuclear power plant into the ocean.
Officials from Fukushima Prefecture and the towns of Okuma and Futaba, which host the plant, conveyed their decision to the president of Tokyo Electric Power Company on Tuesday.
TEPCO, the operator of the plant, had sought the approval of those authorities based on a safety agreement.
Reactors at the Fukushima Daiichi plant suffered meltdowns in the March 2011 earthquake and tsunami disaster.
Water used to cool molten fuel mixes with rain and groundwater. The accumulated water is treated to remove most of the radioactive materials and stored in tanks on the plant’s premises.
The filtered water still contains tritium. The government plans to dilute the water, so that the percentage of tritium is well below the percentage permitted by national regulations. The amount of tritium in the diluted water is also expected to be below the guidance levels for drinking water quality established by the World Health Organization.
The utility is now set to start full-fledged construction of the underwater tunnel and other facilities. It hopes to complete the work around spring of next year.
In July, the Nuclear Regulation Authority gave its final approval for the plan that TEPCO drew up.
One focal point had been whether the local authorities would approve the plan.
Locals, including fishers, are concerned about potential reputational damage to the region.
Construction of Fukushima water release facilities to begin Thurs.

August 3, 2022
TOKYO (Kyodo) — Construction of facilities to discharge treated water from the crippled nuclear power plant in Fukushima Prefecture into the sea will commence Thursday, according to the plant operator, even as opposition at home and abroad remains.
Tokyo Electric Power Company Holdings Inc. said at a press conference Wednesday it still aims to begin releasing the treated water containing tritium about 1 kilometer off the Pacific coast around next spring after diluting it with seawater to one-40th of the maximum concentration permitted under Japanese regulations.
But the plan could be delayed until next summer due to the tight schedule.
Initially, TEPCO had planned to start constructing the facilities in June but it was only approved in July by the Nuclear Regulation Authority.
The tanks storing treated water on the premises of the Fukushima Daiichi plant are expected to reach full capacity around next fall, according to TEPCO’s calculation.
Construction will start after approval was given earlier in the week by the Fukushima prefectural government and two municipalities hosting the seaside power plant, severely damaged after a massive earthquake and tsunami in March 2011 caused core meltdowns at multiple nuclear reactors.
Water that has become contaminated after being pumped in to keep the melted fuel cool has been accumulating at the complex, also mixing with rainwater and groundwater at the site.
TEPCO and the government still face a tall task to persuade fishing communities in Japan and neighboring China, who continue to oppose the release of the treated water on safety grounds.
“It is important for us to make the best effort to clear various concerns and anxiety over the discharge plan,” a TEPCO official said.
Chinese Foreign Ministry spokeswoman Hua Chunying reiterated her country’s opposition to Japan’s plan, calling it “irresponsible” and saying it takes no heed of concerned countries.
The South Korean government has also been expressing concern following the approval by the NRA, it said it will seek responsible handling of the situation by Japan under the principle that people’s health and safety are of the highest priority.
Taiwan’s nuclear energy council said it respects Japan’s decision as it believes the nuclear regulator made the decision on a legal basis and using its expertise.
Local government chiefs from the prefecture on Wednesday also called on the central government to take measures to prevent reputational damage to marine products, a key issue that severely impacted local businesses in the wake of the Fukushima nuclear disaster.
The mayors of Okuma and Futaba, the two towns hosting the Fukushima plant, and Fukushima Gov. Masao Uchibori made the request during a meeting with Economy, Trade and Industry Minister Koichi Hagiuda in Tokyo.
“The plan has not earned enough understanding from Japanese people and residents of the prefecture, as there are still various opinions including concerns over renewed reputational damage,” Uchibori said at the meeting, which was partially open to the media.
Okuma Mayor Jun Yoshida also urged the government to lead from the front, saying, “We hope people in the disaster-stricken area will no longer suffer from reputational damage.”
Hagiuda responded that the plan will be carried out on the premise of ensuring safety and taking thorough measures to prevent reputational damage, adding, “We will deliver information based on scientific evidence throughout the country and abroad.”
For the fisheries industry that faces the risk of damage caused by harmful rumors, it is important to create an environment where their products are traded at fair prices so young people can continue to operate businesses without worries, the local leaders’ request said.

Construction begins at Fukushima plant for water release
The construction of facilities needed for a planned release of treated radioactive wastewater into the sea next year from the damaged Fukushima nuclear power plant has begun despite opposition from the local fishing community

ByMARI YAMAGUCHI Associated Press
August 04, 2022,
TOKYO — The construction of facilities needed for a planned release of treated radioactive wastewater into the sea next year from the damaged Fukushima nuclear power plant began Thursday despite opposition from the local fishing community.
Plant workers started construction of a pipeline to transport the wastewater from hillside storage tanks to a coastal facility before its planned release next year, according to the plant operator, Tokyo Electric Power Company Holdings.
The digging of an undersea tunnel was also to begin later Thursday.
Construction at the Fukushima Daiichi plant follows the Nuclear Regulation Authority’s formal approval last month of a detailed wastewater discharge plan that TEPCO submitted in December.
The government announced last year a decision to release the wastewater as a necessary step for the plant’s ongoing decommissioning.
A massive earthquake and tsunami in 2011 destroyed the Fukushima Daiichi plant’s cooling systems, causing triple meltdowns and the release of large amounts of radiation. Water that was used to cool the three damaged and highly radioactive reactor cores has since leaked into basements of the reactor buildings but was collected and stored in tanks.
TEPCO and government officials say the water will be further treated to levels far below releasable standards and that the environmental and health impacts will be negligible. Of more than 60 isotopes selected for treatment, all but one — tritium — will be reduced to meet safety standards, they say.
Local fishing communities and neighboring countries have raised concerns about potential health hazards from the radioactive wastewater and the reputation damage to local produce, and oppose the release.
Scientists say the impact of long-term, low-dose exposure to not only tritium but also other isotopes on the environment and humans are still unknown and that a release is premature.
The contaminated water is being stored in about 1,000 tanks that require much space in the plant complex. Officials say they must be removed so that facilities can be built for its decommissioning. The tanks are expected to reach their capacity of 1.37 million tons in autumn of 2023.
TEPCO said it plans to transport treated and releasable water through a pipeline from the tanks to a coastal pool, where it will be diluted with seawater and then sent through an undersea tunnel with an outlet about 1 kilometer (0.6 miles) away to minimize the impact on local fishing and the environment.
TEPCO and the government have obtained approval from the heads of the plant’s host towns, Futaba and Okuma, for the construction, but local residents and the fishing community remain opposed and could still delay the process. The current plan calls for a gradual release of treated water to begin next spring in a process that will take decades.
On Wednesday, Fukushima Gov. Masao Uchibori and the two mayors visited Tokyo and asked Economy and Industry Minister Koichi Hagiuda to ensure safety and prevent further damage to the reputation of Fukushima fishing products.
Akira Ono, TEPCO chief decommissioning officer at the plant, promised the highest efforts to ensure safety and understanding.
“We are aware of various views on reputational impact and safety concerns (of the release) and we’ll keep explaining throughly to stakeholders,” he said.
TEPCO said Wednesday that weather and sea conditions could delay a completion of the facility until summer 2023.
Japan has sought help from the International Atomic Energy Agency to ensure the water release meets international safety standards and reassure local fishing and other communities and neighboring countries, including China and South Korea, that have opposed the plan.
IAEA experts who visited the plant earlier this year said Japan was taking appropriate steps for the planned discharge.
Japan’s Mihama nuclear plant reports radioactive water leak, sparking concerns after Fukushima discharge plan

August 2, 2022
About 10 days after Japan’s nuclear regulator approved the plan to discharge nuclear-contaminated water from the Fukushima power plant, another nuclear power plant in central Japan leaked about seven tons of water containing radioactive elements, sparking wide concern over safety of Japan’s nuclear power plants.
Also, on Tuesday the local government in Fukushima Prefecture agreed to allow Tokyo Electric Power Company (TEPCO) to build facilities to dump the nuclear-contaminated water, Japan’s NHK reported. The Nuclear Regulation Authority of Japan on July 22 officially approved the water discharge plan.
According to the operator Kansai Electric Power Company, about seven tons of radioactive water leaked from Mihama 3 reactor at the Mihama nuclear power plant in Fukui Prefecture on Monday. The amount of radioactivity of the leaked water is about 2.2 million becquerels (Bq).
According to the Waste Management and Recycling Department, Japanese Ministry of the Environment, 100Bq/kg is the standard for safe recycling of waste and 8,000Bq/kg is the standard for safe disposal of waste.
The company claimed that the leak was contained and had no impact on the external environment.
The over 40-year-old reactor is currently out of service. The company is investigating whether the leak will affect the reactor’s scheduled restart in mid-August, Japanese media outlet Sankei News reported.
The aging Mihama 3 reactor has a stained history. In August 2004, a pipeline of the reactor broke down, which killed five and seriously injured six people, according to the Yomiuri Shimbun.
Voices from civil society have expressed their deep concern over the Mihama nuclear power plant.
According to Kyoto Shimbun, a civil group on Friday urged the governor of Shiga Prefecture to publicly announce their opposition to the Kansai Electric Power Company’s plan to restart Mihama 3 in mid-August.
The latest radioactive water leak and the dumping of Fukushima nuclear waste have largely overdrawn the credit of the Japanese authorities and related companies, according to both netizens from Japan and China.
A Japanese netizen said the old Mihama reactor has long been in bad condition. Another Japanese netizen said the accident could be intentional.
“The leak will not affect the outside environment. Really? Japan said the same thing when they decided to dump the Fukushima nuclear-contaminated water into the sea!” said a Chinese netizen.
Zhang Yancang, director of the Yellow Sea and Bohai Sea Research Institute of Dalian Maritime University, told the Global Times on Tuesday that the ocean is not Japan’s sewage disposal site, and the marine ecology is an organic whole, so once the pollution spreads, it may affect the entire body. Most countries, including the US, cannot be immune to it.
According to the United Nations Convention on the Law of the Sea, states should hold an international legal obligation to combat transboundary pollution of the oceans. However, Japan has prepared for a long time to avoid legal responsibility for dumping nuclear-contaminated water and radioactive water leaks, Zhang said.
