A million tons of Fukushima’s radioactive water – what to do with it?
THE TSUNAMI-DRIVEN SEAWATER that engulfed Japan’s Fukushima Daiichi nuclear plant has long since receded. But plant officials are still struggling to cope with another dangerous flood: the enormous amounts of radioactive water the crippled facility generates each day. More than 1 million tons of radiation-laced water is already being kept on-site in an ever-expanding forest of hundreds of hulking steel tanks—and so far, there’s no plan to deal with them.
The earthquake and tsunami that hammered Fukushima on March 11, 2011 triggered meltdowns in three of its six reactors. That left messes of intensely radioactive fuel somewhere loose in the reactor buildings—though no one knows exactly where. What is known, however, is that every day, as much as much as 150 tons of groundwater percolates into the reactors through cracks in their foundations, becoming contaminated with radioactive isotopes in the process.
To keep that water from leaking into the ground or the Pacific, Tepco, the giant utility that owns the plant, pumps it out and runs it through a massive filtering system housed in a building the size of a small aircraft hangar. Inside are arrays of seven-foot tall stainless steel tubes, filled with sand grain-like particles that perform a process called ion exchange. The particles grab on to ions of cesium, strontium, and other dangerous isotopes in the water, making room for them by spitting out sodium. The highly toxic sludge created as a byproduct is stored elsewhere on the site in thousands of sealed canisters.
This technology has improved since the catastrophe. The first filtering systems, installed just weeks after the disaster by California-based Kurion Inc. (which has since been bought by Veolia, a French resource management company), only caught cesium, a strong gamma radiation emitter that makes it the most dangerous of the isotopes in the water. The tubes in those arrays were filled with highly modified grains of naturally occurring volcanic minerals called zeolites. By 2013, the company developed entirely artificial particles—a form of titano silicate—that also grab strontium.
So for now, the tritiated water is pumped into a steadily growing collection of tanks. There are already hundreds of them, and Tepco has to start building a new one every four days.
Tepco has at least reduced the water’s inflow. As much as 400 tons per day was gushing in just a couple of years ago. In an effort to keep the groundwater from getting in, Tepco has built a network of pumps, and in 2016 installed an underground “ice wall”—a $300 million subterranean fence of 30-yard-long rods through which tons of sub-zero brine is pumped, freezing the surrounding earth. All of which helps, but hasn’t solved the problem……… https://www.wired.com/story/fukushimas-other-big-problem-a-million-tons-of-radioactive-water/
Japanese trading house Itochu ‘pulls out of nuclear plant project in Turkey’
Japanese Itochu ‘pulls out of nuclear plant project in Turkey’http://www.hurriyetdailynews.com/japanese-itochu-pulls-out-of-nuclear-plant-project-in-turkey-130811, TOKYO , 24 Apr 18
Japanese trading house Itochu is pulling out of a nuclear power plant project in Turkey due to a surge in safety-related costs, casting uncertainty over the plant’s future as well as the Japanese government’s infrastructure export ambitions, as reported by Nikkei on April 24.
The project was agreed on by the Japanese and Turkish governments in 2013. A consortium including Itochu and Mitsubishi Heavy Industries had been conducting a feasibility study until March for the construction of a 4,500-megawatt plant in the city of Sinop in Turkey’s Black Sea region.
But costs related to safety measures surged after the Fukushima Daiichi nuclear disaster in 2011, and the estimated costs for the project ballooned to more than five trillion yen ($46.2 billion) from two trillion yen in 2013, according to the report.
Itochu, which was jointly conducting the feasibility study with its consortium partners, is expected to avoid involvement in the project. Mitsubishi Heavy and other investors in the consortium have already extended the feasibility study until this summer.
Initially, 30 percent of the project’s cost was planned to be covered by the consortium and 70 percent by loans from the Japan Bank for International Cooperation and other lenders.
The consortium was expected to be 51 percent owned by Mitsubishi Heavy, Itochu and French electric utility Engie, and 49 percent by others entities, including the Turkish Electricity Generation Corporation.
The departure of deep-pocketed Itochu will make the project more risky for Mitsubishi Heavy, which is requesting the Turkish government to change the ownership structure of the consortium.
Despite local opposition, another Genkai nuclear reactor to be restarted
The rebooting of the No. 4 unit at the plant in Saga Prefecture after a six-year hiatus will complete Kyushu Electric Power Co.’s plan to bring four of its reactors online after the country’s regulator implemented stricter screening following the Fukushima nuclear disaster in 2011.
According to the plan submitted to the Nuclear Regulation Authority, the company will restart the reactor on May 24 if preparations go smoothly, with commercial operation slated for late June.
Kyushu Electric restarted the No. 3 reactor at the Genkai plant in March. At the company’s Sendai complex in Kagoshima Prefecture, two reactors came back online in 2015.
Some local residents have been opposed to the Genkai plant’s operation, questioning the validity of safety standards and citing the risk of volcanic eruptions in the region. The Saga District Court rejected in March a request for an injunction to suspend the plant’s restart.
Japan ‘covering up’ Fukushima nuclear danger-zone radiation levels and blackmailing evacuees to return to radiated areas swarming with radioactive pigs and monkeys

Three reactors went into meltdown after the 2011 Japanese tsunami in the worst accident since Chernobyl, leaving an apocalyptic vision of ghost towns and overgrown wildernesses and scared residents refuse to return
JAPAN is lying to the world about nuclear-ravaged Fukushima’s recovery while forcing terrified evacuees to return to their radioactive homes, it is claimed.
More than seven years after the nuclear catastrophe rocked the world, many of the 154,000 people who fled their homes have not returned and towns remain deserted.
Thousands of irradiated wild boars and monkeys roam around while poorly paid and protected decontamination workers scrub homes, schools and shops down ready for people to come home.
Chilling footage of taken inside the evacuated areas of Fukushima City and Köryama lay bare the disaster that unfolded after an earthquake, measuring 9.01 on the Moment Magnitude scale, struck off the coast of Japan on March 11, 2011.
But it was the following 50ft tsunami that damaged reactors at the Fukushima nuclear power plant.
This led to the evacuation of thousands of people from a 12-mile exclusion zone, with roads guarded by roadblocks and officials in protective gear.
Now there is a big campaign is under way to make people return but residents, campaigners and experts believe it not safe.
They accuse the Japanese authorities of wanting to allay public fears over the nuclear power by downplaying the dire consequences of the leak.
Propaganda videos showing the remarkable recovery of Fukushima have been spread by the government on its social media accounts.
“Since the Great East Japan Earthquake in 2011, #Fukushima has been working towards a bright future.
Strict safety standards and monitoring means that #food from the prefecture is enjoyed all over #Japan.” See Fukushima’s amazing recover in this video:http://bit.ly/2CqP0HC
But senior nuclear specialist Shaun Burnie, from Greenpeace Japan, said the nuclear nightmare continues.
He said: “They are not telling the whole truth either to the 127 million people of Japan or to the rest of the world – about the radiation risks in the most contaminated areas of Fukushima.
“The nuclear crisis is not over – we are only in year seven of an accident that will continue to threaten public health, and the environment, for decades and well into the next century.
“Attempts by the government and the nuclear industry communicate that it is safe and it’s over are a deliberate deception.”
Most of Japan’s power plants shut in the wake of the Fukushima nuclear disaster.
But in 2015 the Prime Minister announced plans to restart reactors because the economy needed cheap energy and using fossil fuels risked huge carbon emission fines.
Now five of them are back on – and it’s aimed to to have at least 12 in use by 2025.
The nuclear crisis is not over – we are only in year seven of an accident that will continue to threaten public health, and the environment, for decades and well into the next century (Senior nuclear specialist Shaun Burnie)
Mr Burnie said: “If they can create the illusion of the region that that has recovered from the nuclear accident they think it will reduce public opposition.”
But meanwhile the crisis continues at the Fukushima plant.
He said: “The massive Ice Wall built at the nuclear plant to stop contamination of groundwater is a symbol of this failure and deception – this is no Game of Thrones fantasy but the reality of a nuclear disaster that knows no end.”
Today he says “there were areas of Fukushima where radiation levels could give a person’s maximum annual recommended dose within a week.”
He said: “This is of particular concern with regards to poorly paid decontamination workers, thousands of whom have been involved in attempts to decontaminate radiation around people’s homes, along roads and in narrow strips of forest.”
Mr Burnie said the government claims decontamination has been completed in 100 percent of affected areas after a £8bn clean up operation.
But he added: “What they don’t explain is that 70-80 percent of areas such as Namie and Iitate – two of the most contaminated districts – are forested mountain which it is impossible to decontaminate.
“In areas opened in March 2017 for people to return – radiation levels will pose a risk until the middle of the century.
“These areas are still to high in radiation for people to return safely – and is one reason so few people are returning.”
Meanwhile heavy-handed tactics are being used with some fearful residents reporting that they have been warned they won’t receive lifeline compensation cash if they don’t comply.
Dr Keith Baverstock, a radiation health expert who was at the World Health Organization at the time disaster, told Sun Online: “For the past two years the Japanese government has encouraged the evacuees to return to their homes, but relatively few people have taken up this offer, even though there is a threat – it may even now be a fact – that their compensation will cease.”

Pressure on assistant professor to downplay dangers of nuclear power

Hokkaido METI bureau requested changes to nuclear energy part of high school lecture https://mainichi.jp/english/articles/20180407/p2a/00m/0na/017000c (Mainichi Japan) SAPPORO –– High-ranking officials from the local bureau of the Ministry of Economy, Trade and Industry (METI) requested that an assistant professor change an October 2017 lecture to high school students pointing out the dangers of nuclear power, it has been learned.
“We will review our operations so as not to cause misunderstandings,” stated industry minister Hiroshige Seko regarding the request by the Hokkaido Bureau of Economy, Trade and Industry.
The lecture at Hokkaido Niseko High School in the prefectural town of Niseko was on energy issues. The school had been chosen by the Agency for Natural Resources and Energy, an industry ministry-affiliated body, as a model for energy education last academic year, and the lecture by Hokkaido University assistant professor Sadamu Yamagata was supported by a government grant.
According to multiple sources close to the matter, Yamagata sent his lecture materials to the school beforehand to be printed, and the school handed the documents over to METI’s Hokkaido bureau at the latter’s request. Two high-ranking officials from the bureau then visited Yamagata and requested that he make changes to a section of the materials explaining the dangers and costs of nuclear power, illustrated with a photo of the aftermath of a hydrogen explosion at the Fukushima No. 1 Nuclear Power Plant. The officials told Yamagata that this was “only one perspective” and that called it “impression manipulation.”
Yamagata added the statement, “natural energy is not necessarily 100 percent safe” along with a photo of a collapsed windmill, but did not comply with the request to change the section about nuclear energy.
“I found it uncomfortable that (the request for changes) was focused on nuclear power,” Yamagata told the Mainichi Shimbun. Hokkaido Niseko High School principal Noboru Baba said, “The lecture content was good. I don’t know if there was intrusion (by the ministry) into education.” However, residents who were aware of what had happened view the flow of events as meddling by the government in education, and the Niseko Municipal Government has held three meetings to explain the situation to locals.
Industry minister Seko told a post-Cabinet meeting news conference on April 6, “It’s common sense that the government takes responsibility for the content of an agency-commissioned program, but with the focus (by the bureau officials) only on nuclear energy, misunderstandings can arise easily.”
The incident comes on the heels of criticism of the Ministry of Education, Culture, Sports, Science and Technology for pressuring the Nagoya Municipal Board of Education by requesting a report about a lecture given by former vice minister of education Kihei Maekawa.
But how should the Hokkaido case be understood? The class taught by Maekawa was set up by the school and the Nagoya education board, completely independently of the central government. On the other hand, the Hokkaido case was funded by a central government grant, and Japan’s stance has so far been that funding gives related government bodies a say in how the monies are used.
The Hokkaido bureau’s Natural Resources, Energy and Environment Department denied intervening, telling the Mainichi, “The purpose was to show both the merits and demerits of all types of energy sources, and if the lecture had hypothetically been extremely critical of natural energy resources, the same request for alternations would have been made. If only the shortcomings of nuclear energy are presented while ignoring the benefits, that is a problem.”
However, experts are critical. Hokkaido University emeritus professor Yoichi Anezaki said, “The case of the education ministry requesting a report of Maekawa’s class was also problematic, but in this case with the industry ministry, which plays a key role in nuclear power policies, requesting that a section pointing out the issues with nuclear energy be changed, it’s an intrusion into education by authority and is much worse. It’s tantamount to censorship.”
“The belief that just because the government provided the grant, it means that it can have its say on the content of education doesn’t make sense,” said Kyoto University of Art and Design professor and former education ministry bureaucrat Ken Terawaki. “If we allow for this, then it means that it’s fine for the Ministry of Foreign Affairs to promote the Trans-Pacific Partnership and the Ministry of Defense the necessity of military affairs in the classroom. Intrusion into education is a serious matter.”

Powerful volcanic eruption at Mount Shinmoe, and more to come -ONLY 40 MILES FROM Sendai Nuclear power station
Another powerful eruption observed at Mount Shinmoe , Japan Times, 5 Apr 18 FUKUOKA – Another powerful eruption was observed at Mount Shinmoe in southwestern Japan early Thursday, with ash sent spiralling into a plume around 5,000 meters high, the Meteorological Agency said.
The eruption at the 1,421-meter volcano that straddles Miyazaki and Kagoshima prefectures was the largest since March 25, according to the agency.
Mount Shinmoe erupted violently for the first time in about seven years on March 6, and the agency said a week later that it was expected to continue explosive eruptions for several months or more……..https://www.japantimes.co.jp/news/2018/04/05/national/another-powerful-eruption-observed-mount-shinmoe/#.WsggQIhubIU
The end for Japan’s expensive Monju nuclear fast breeder dream
Japan prepares to shut troubled ‘dream’ nuclear reactor https://asia.nikkei.com/Politics/Japan-prepares-to-shut-troubled-dream-nuclear-reactor
Decades-old plant has cost almost $10bn and hardly ever operated
TOKYO — Japan is set to start decommissioning its troubled Monju fast-breeder reactor after decades of accidents, cost overruns and scandals. It is the beginning of the end of a controversial project that exposed the shortcomings of the country’s nuclear policy and the government’s failure to fully explain the risks and the costs.
In July, the Japan Atomic Energy Agency will begin decommissioning what was hailed as a “dream” reactor that was expected to produce more nuclear fuel than it consumed. The government has so far spent more than 1 trillion yen ($9.44 billion) on the plant, which has barely ever operated.
The plan approved by the Nuclear Regulation Authority on March 28 to decommission the reactor, located in central Japan’s Fukui Prefecture, calls for the extraction of spent nuclear fuel to be completed by the end of the fiscal year through March 2023. Full decommissioning is expected to take about 30 years.
Japan does not have the technological ability to manage the decommissioning process on its own, and must enlist the help of France, which has more experience with fast-breeder reactors. Among the technical challenges is handling the plant’s sodium coolant, which is highly reactive and explodes on contact with air.
Many of the problems with Japan’s nuclear policy were brought to light by the Fukushima Daiichi nuclear disaster caused by the tsunami and earthquake of March 2011. Such problems have included the high costs of plants, the selection of nuclear disposal sites, and the threat of shutdowns due to lawsuits. Japan’s nuclear policy has largely been gridlocked since the disaster.
But the Monju project had many problems before the Fukushima catastrophe.
Planning for the project began in the 1960s. Its fast-breeder technology was considered a dream technology for resource-poor Japan, which had been traumatized by the oil crisis of the 1970s. The reactor was supposed to generate more plutonium fuel than it consumed.
The reactor finally started operating in 1994, but was forced to shut down the following year due to a sodium leak. It has been inoperative for most of the time since. The decision to decommission it was made in December 2016 following a series of safety scandals, including the revelation that many safety checks had been omitted.
Recent experience suggests the government’s estimated cost of 375 billion yen to decommission Monju could be on the low side. In 2016, the estimate for decommissioning the Fukushima Daiichi plant ballooned to 8 trillion yen from an initial 2 trillion yen in 2013, largely due to inadequate understanding of the decommissioning process.
While “the JAEA will try to keep costs down,” said Hajime Ito, executive director with the agency, the process of extracting sodium, the biggest hurdle, has yet to be determined. Future technical requirements will also involve significant costs.
The Monju reactor is not the only example of failure in Japan’s nuclear fuel cycle policy — the cycle of how nuclear fuel is handled and processed, including disposing nuclear waste and reprocessing used fuel.
Central to this policy is a nuclear fuel reprocessing plant in the village of Rokkasho in northern Aomori Prefecture that was supposed to extract plutonium and uranium by reprocessing spent nuclear fuel to be reused at nuclear plants.
More than 2 trillion yen has been spent on the plant so far. Construction was begun in 1993, but completion has been repeatedly postponed due to safety concerns. On Wednesday, the NRA decided to resume safety checks on the plant, but if it chooses to decommission it, the cost would be an estimated 1.5 trillion yen.
Had Japan taken into consideration the costs of decommissioning plants and disposing of spent nuclear fuel, it probably would not have been able to push ahead with its nuclear policy in the first place, said a former senior official of the Ministry of Economy, Trade and Industry, who was involved in formulating the country’s basic energy plan.
Decommissioning of Japan’s nuclear stations: is it really worth the cost – to reactivate any of them?

Japan Times 1st April 2018, The recent decision by Shikoku Electric Power Co. to decommission the aging
No. 2 reactor at its Ikata nuclear facility in Ehime Prefecture serves as
yet another reminder that tightened safety regulations and market
conditions in the aftermath of the 2011 Fukushima crisis are imposing a
heavy financial burden on power companies that run nuclear power plants.
Whether or not they push for reactivating the reactors idled in the wake of
the 2011 accident, both the government and the power industry are urged to
reassess the economics of nuclear power to determine whether they are still
worth the cost.
The Ikata reactor is the ninth at six nuclear power plants
across Japan to be decommissioned after the 2011 disaster, not including
the six at Tokyo Electric Power Co.’s Fukushima No. 1 plant, which was
crippled by the meltdowns at three of its six reactors in March 2011 after
the plant was flooded by giant tsunami in the Great East Japan Earthquake.
All of the reactors were aging and nearing the 40-year limit on their
operation, and the power companies were faced with the question of whether
to decommission the reactors or apply to the Nuclear Regulation Authority
for approval of a one-time extension of their operation for another 20
years — which would have entailed costly additional investments to bump
up their safety under the post-Fukushima rules. https://www.japantimes.co.jp/opinion/2018/04/01/editorials/reassess-economics-nuclear-power/
Tepco facing huge costs in Fukushima disaster, but still plans to help fund restart of Tokai nuclear power station.
TEPCO, Tohoku Electric to give Japan Atomic financial boost to help restart reactor https://mainichi.jp/english/articles/20180329/p2a/00m/0na/015000c,
The hefty sum is the estimated cost of safety upgrades required by the Nuclear Regulation Authority (NRA) to restart the plant in the village of Tokai, Ibaraki Prefecture. The NRA, which carries out mandatory plant inspections ahead of any reactor restart, has requested Japan Atomic to submit a plan to secure the necessary funds for the safety measures.
However, Japan Atomic’s sole business is nuclear power generation, and both its two reactors are currently stopped. The company has only survived this far thanks to the basic annual fee of about 100 billion yen included in its power supply contracts with Japan’s five big electric utilities. Under these conditions, it looked extremely difficult for Japan Atomic to cover the Tokai No. 2 station upgrade costs on its own, and the firm appealed to TEPCO and Tohoku Electric — both of which have power purchase contracts for electricity from the plant — for support.
TEPCO and Tohoku Electric are set to decide on March 30 to accept Japan Atomic’s plea for financial help and open discussions, and notify the power producer. Japan Atomic will in turn present the outside aid to an upcoming NRA inspection committee meeting.
Regarding the aid, TEPCO and Tohoku Electric will consider guaranteeing loans to Japan Atomic from its creditors. However, the utilities plan to make that decision once they have evaluated progress on the inspections needed for the Tokai No. 2 plant to be restarted, and examined the formal construction cost estimates for the necessary safety upgrades.
The announcement of TEPCO and Tohoku Electric’s financial backing for Japan Atomic will bolster the case for the Tokai No. 2 station’s return to operation. However, the restart faces hurdles, including obtaining local resident approval and the need for the surrounding local governments to draw up evacuation plans in case of a serious accident at the plant. Thus, even if the power station does pass the NRA inspections, there is no guarantee it can be restarted.
Furthermore, TEPCO is also liable for tremendous costs associated with dealing with the Fukushima No. 1 nuclear plant disaster, and the company could face criticism for offering financial aid to Japan Atomic under these conditions.
375 billion yen (2.86 billion euros) to dismantle Japan’s Monju breeder nuclear reactor
Le Monde 1st April 2018, [Machine Translation] By validating, on Wednesday 28 March, the project to
dismantle the Monju breeder reactor, the Nuclear Regulatory Authority (ARN)
thwarting Japan’s ambition to control the fuel cycle and adds a new nuclear
bill in the archipelago. The project involves a dismantling over thirty
years of the facility built in Tsuruga in the department of Fukui (center).
It should cost 375 billion yen (2.86 billion euros). The operation will
start as soon as July by the removal of the fuel. Then the sodium –
liquid delicate cooling to handle because flammable on contact with air –
will be removed. Disassembly will follow, with an end scheduled for 2048.

Closing down of Fukushima nuclear power plant has skyrocketed to US$75 billion
Oil Price 30th March 2018, The decommissioning of the Fukushima nuclear power plant will cost an
annual US$2 billion (220 billion yen) until 2021, an unnamed source told
the Japan Times. Half of the money will be used to tackle the radioactive
water buildup at the site of the plant and for removing radioactive fuel
from the fuel pools. A small amount of funds will be used to research ways
of retreating melted fuel from the reactors that got damaged during the
2011 tsunami disaster.
The US$6 billion for the three years is only part of
the total estimated cost for taking Fukushima out of operation. The total
decommissioning tally came in at US$75 billion (8 trillion yen), as
estimated by the specially set up Nuclear Damage Compensation and
Decommissioning Facilitation Corp (NDF).
That’s four times more than the initial estimate of the costs around the NPP’s decommissioning. Now theoperator of Fukushima, Tepco, and the NDF are due to submit their financial plan for the facility to the government for approval by the energy industry
minister. In addition to the US$6 billion allocated for the cleanup, Tepco
will spend another US$1.88 billion (200 billion yen) on preparing to start
extracting the melted fuel from the three damaged reactors. This seems to
be the biggest challenge for the cleanup efforts because of the still high
radiation levels as well as technical difficulties. https://oilprice.com/Latest-Energy-News/World-News/Total-Tally-For-Fukushima-Decommission-Is-75-Billion.html
