August’s 3rd worker died in Fukushima plant after the work of retained contaminated water beside Reactor 1
On 8/22/2015, Tepco announced another Fukushima worker died in the plant.
This is not covered by the mass media for some reason.
At 13:10 of 8/21/2015, it was reported to the emergency headquarters that a subcontract worker lost the consciousness. The worker was transporting equipment related to the retained contaminated water beside Reactor 1 turbine building.
The worker was sent to Iwaki Kyouritsu Hospital by ambulance but confirmed to be dead at 15:47 of the day.
The age and gender are not reported.
In August, 3 workers are already dead in Fukushima plant.

Behind the Scenes / Proving negligence in TEPCO case daunting
On July 31, the Tokyo No. 5 Committee for the Inquest of Prosecution announced its decision that former Tokyo Electric Power Co. Chairman Tsunehisa Katsumata, 75, and two other former company executives “should be indicted” in connection with the Fukushima No. 1 nuclear power plant disaster.
In this case the “will of the people” has spoken to counter the prosecutor’s decision not to indict, but proving culpable negligence in an accident associated with a natural disaster will be difficult. The prosecution’s designated lawyer is expected to face an uphill battle to convict the three men.
Concrete recognition
“The decision clearly states that [TEPCO] should’ve been able to foresee the onslaught of the tsunami,” said Hiroyuki Kawai, lawyer for the Complainants for the Criminal Prosecution of the Fukushima Nuclear Disaster, at a press conference held in Tokyo following the decision to indict. “The prospects for the trial are bright.”
The inquest committee and the prosecution, however, are far apart over whether the three individuals accused could “foresee” the likelihood of a massive tsunami and the ensuing disaster.
In 2008, TEPCO published the results of preliminary calculations that predicted a maximum credible tsunami of 15.7 meters based on a long-term assessment by the government’s Headquarters for Earthquake Research Promotion.
The Tokyo District Public Prosecutors Office concluded that establishing “foreseeability” meant more concrete evidence was needed beyond a vague foreboding of danger or anxiety, deemed that TEPCO’s preliminary tsunami reports couldn’t be regarded as having the scholarly persuasiveness necessary and denied foreseeability on the part of the company’s former officers and others.
The inquest committee, made up of 11 members of the public, responded that “it is sufficient that there must be foreseeability given the fact that a tsunami occurred and some sort of response was required.”
The committee stressed that the three individuals accused had a duty to exercise a high degree of care to prevent accidents since they all held positions of responsibility, and that the maximum credible tsunami report “absolutely could not be ignored.”
‘A certain extent’
Nevertheless, a big hurdle must be cleared to prove criminal responsibility for negligence when accidents occur.
“Jurists and the general public look at foreseeability and the duty to exercise care differently,” one veteran judge noted. “Proving foreseeability could be difficult to prove on the basis of preliminary tsunami calculations.”
In the JR Fukuchiyama Line derailment accident in Amagasaki, Hyogo Prefecture, three successive presidents of West Japan Railway Co. were subjected to mandatory indictment on a charge of corporate manslaughter.
The inquest committee for the case, which is currently under appeal, said, “Even in the most basic civic sense, stringent safety measures should obviously be taken as quickly as possible.”
Yet at the trial and the first appeal, the court ruled the three were not guilty as the three successive presidents could not have foreseen the accident.
The Fukushima nuclear disaster was caused by a natural phenomenon that would have been difficult to predict, making the charge even more of a challenge to prove.
“The purpose of criminal law is to pursue the responsibility of individuals,” said Tokai University Prof. Yoshihiko Ikeda, who specializes in criminal-negligence theory. “In terms of large-scale accidents related to disasters, senior management can be held responsible for negligence only to a certain extent.”
Choice of words
Now that a decision to indict has been made, the Tokyo District Court chose Friday three designated lawyers for the prosecution who will carry out supplementary investigations. The three accused might be subjected to mandatory indictment by the end of the year at the earliest.
All eyes are on what TEPCO’s former executives will say in court regarding the unprecedented accident.
Lawyer Motoharu Furukawa, a former prosecutor and author of books like “Fukushima gempatsu, sabakarenai de ii no ka” (Is it right to not take the Fukushima nuclear power plant to court?), published by Asahi Shimbun Publications Inc., says: “It’s of great importance that this be delved into publicly in court. It may even lead to a rethinking of nuclear power safety policy.”
Why did a major disaster that led to reactor meltdowns take place? Was there no way the accident could have been prevented?
Aside from the question of criminal responsibility, Katsumata and his associates need to present the full truth in court.
Doubts over system
The mandatory-indictment system was instituted in May 2009 so the “will of the people” would be reflected in judgments over whether or not to indict, judgments that hitherto had been the sole preserve of prosecutors.
While there is praise for the fact that, with this system in mind, prosecutors have become more cautious in deciding not to indict, a string of cases that used mandatory indictment have nevertheless ended in acquittals, exposing certain problems in the system.
First of all, the mandatory indictment system provides no opportunity for those under inquest to present their side of the story.
The Law for the Inquest of Prosecution makes it mandatory for a prosecutor to present the case prior to any decision to indict, but the accused forced into a public trial through a mandatory indictment has no opportunity to contest the charges beforehand.
“Would it not be a good idea to consider hearing the side of those under indictment, even if just to maintain the fairness of the inquest?” said Yasuyuki Takai, a lawyer who was involved in designing the system.
Then there’s the fact that the role of “inquest assistant,” which gives legal advice to the inquest committee, is limited to a single individual. A lawyer is appointed as inquest assistant, who responds to queries from the committee members.
Yukio Yamashita, a lawyer who has experience as an inquest assistant, pointed out that for a single individual “explaining legal arguments to the general public is difficult.”
“For a truly adequate inquest multiple assistants would be necessary,” Yamashita said.
Another problematic point is how the designated lawyer bears an excessive burden.
Proving guilt in a case where the prosecution has chosen not to indict is difficult — the maximum compensation paid to a designated lawyer for a single trial or appeal is ¥1.2 million.
The Japan Federation of Bar Associations is said to be planning to submit an opinion calling for improvements to the mandatory-indictment system this year to the Supreme Court and the Justice Ministry.
The system must be revised if it is to live up to its original goal, it seems.

Japan’s Nuclear Gypsies: The Homeless, Jobless and Fukushima
They are called the “precariat,” Japan’s proletariat, living precariously on the knife-edge of the work world, without full employment or job security. They are derided as “glow in the dark boys,” “jumpers,” and “nuclear gypsies.” They have even been dubbed “burakumin,” a hostile term for Japan’s untouchables, members of the lowest rung on the ladder in Japanese society.
Homeless and unemployed or marginally employed day laborers, unskilled and virtually untrained, they are the nuclear decontamination workers recruited by Japanese gangsters, yakuza, to make Fukushima in northern Japan livable again after the 3/11 triune disaster – the Great Tohoku Earthquake and tsunami which precipitated the Fukushima Dai-ichi nuclear power plant meltdown.
These workers have been recruited for one of the most dangerous and undesirable jobs in the industrialized world: working on the $35 billion, taxpayer-funded effort to clean up radioactive fallout across an area of northern Japan larger than Hong Kong. Reuters and the L.A. Times have both remarked that it is an unprecedented effort.
Reuters made a direct comparison between Fukushima and the Chernobyl “incident.” Unlike Ukraine and the 1986 nuclear “accident” at Chernobyl, where authorities declared a 1,000 square-mile no-habitation zone, resettled 350,000 people and decided to let radiation take care of itself, Japan is attempting to make the Fukushima region livable again.
The army of itinerant decontamination workers has been hired at well below the minimum wage to clean up the radioactive debris and build tanks to store the contaminated water generated to keep the reactor cores cool. They work in noisome unregulated environs, without adequate supervision, training or monitoring or the protection of health insurance.
Most of the workers are subcontractors, drifters, unskilled and poorly paid. In an article for Al Jazeera’s America Tonight, David McNeill, blogger about nuclear gypsies, commented: “They move from job to job. They’re unqualified, of course, in most cases.”
Jeff Kingston, Dept. of Asian Studies, Temple University Japan, noted in October 2014 that the numbers of these nuclear gypsies or members of the “precariat” -have been seen to have risen from 15 percent of the Japanese workforce in the late 1980s to 38 percent to date and the numbers are expected to continue to rise.
Jobless, or Just Homeless?
The laborers deputed to carry out this huge ambitious project, Japan’s nuclear gypsies, include both the homeless and those who can be said to be just one notch above homelessness – jobless people. These two classes are often nearly identical. It is perhaps more useful to identify the workers on the decontamination project as the working poor in dire economic straits.
Are these laborers truly homeless? What of a recent survey saying that homelessness has reached an all-time low? Al Jazeera noted in October 2014 that although a 2014 government survey had found that Tokyo’s homeless population had dropped drastically, critics dispute this finding, calling the survey another effort to ignore a population that is contending with growing economic disparity, and exploited for cheap labor.
Charles E. McJilton, CEO of the Food Bank Second Harvest Japan, disputes the numbers of the homeless in Japan. He believes that although actual numbers of the homeless in Tokyo may be down, these numbers fail to take into account the larger issue country-wide of poverty and economic insecurity. Al Jazeera reported him as saying, “It has always been a misunderstanding in the media that poverty in Japan is represented by the homeless.”
Tom Gill of Meiji Gakuin University suggests that the larger problem is the rapidly growing number of people in dire straits.
Many Japanese living on the edge apply for assistance under Japan’s livelihood protection law - seikatsu hogo - which guarantees a basic standard of living. Gill has said that the problem is the sharply increasing number of applications for the generous welfare benefit, and its worsening impact on the national debt, the largest in the developed world.
Well over 500,000 people in Japan have been reported to have lost their jobs since the “Lehman shokku,” the day in September 2008 when Lehman Bros. collapsed and triggered a worldwide financial crisis.
Half the people who lost their jobs were on temporary or part-time contracts that offered them no insurance. Thousands lived in company housing and when they lost their livelihoods, they lost their homes. Today they camp out under blue tarpaulins, sleeping in parks, under bridges, and in railway stations or in 24-hour Internet cafes.
The Christian Science Monitor noted that as of Sept. 2009, twenty million people, one-sixth of Japan’s population, lived below the poverty line. Seventy-seven percent of unemployed Japanese have no unemployment insurance, according to a report earlier in 2009 by the International Labor Organization as cited by the Monitor.
The Monitor also quoted Charles McJilton who once lived as a homeless person in Tokyo for 18 months. “When you fall out of the [workers’] safety net in Japan, you wouldn’t believe what is [no longer readily] available.” He is referring primarily to access to housing, but also to new jobs, food and medicine.
Even the jobless who do find new jobs cannot easily find a new home. The government made 13,000 housing units available to homeless people, and as of September 2009, had filled 7,666 of them. But that is not a lasting solution, argues McJilton. He says that the housing project may have cleared a lot of people off the streets but that “the government is more interested in keeping the peace than in solving the homeless problem.”
As these workers lose their jobs, with few chances of finding another one, younger men are ending up on the streets. The Monitor noted that of the 5,400 people who slept in Internet cafes in 2007, 41 percent were under 30. When they leave the shelters, they are supposed to start looking for work. Only half of them actually do so, however. The other half go back to the streets – often because they see no hope of finding a job.
One nuclear gypsy cited by Reuters in December 2013 summed up a near hopeless situation. “We’re an easy target for recruiters,” Shizuya Nishiyama, 57, says. He briefly worked at Fukushima clearing rubble. He now sleeps in a cardboard box in Sendai Station. “We’re easy to spot. They say to us, are you looking for work? Are you hungry? And if we haven’t eaten, they offer to find us a job.”
These men are sitting ducks, targets for wage slavery at the Fukushima nuclear decontamination project.
TEPCO, Yakuza and Subcontractors
Another nuclear gypsy was even more direct, eloquent and despairing. In its January 2014 report for Al Jazeera’s America Tonight, the laborer Tanaka was quoted as saying: “TEPCO is God. The main contractors are kings, and we are slaves.”
The January 2014 Al Jazeera report further reported that hiring for the cleanup operations is an effort in which the Japanese mafia, the yakuza, is deeply involved. Workers and onlookers who were interviewed said that it is the yakuza’s employment practices which further poison the system.
“The Yakuza have, historically, been deeply embedded in the structure of the construction industry,” explains Takeshi Katsura, a laborer who also helps workers exploited by the Japanese mafia. “It’s the structure that’s evil,” he said.
The subcontracting system and high demand for labor in Fukushima have been a boon for organized crime. “To quickly gather 4,000 to 5,000 decontamination workers in Fukushima, you need to do it the traditional way,” said Katsura. “Using the Yakuza.”
The decontamination industry is particularly appealing to the yakuza, because of the extra government-funded $100-a-day in danger pay per worker. But don’t assume that this pay actually gets to the workers!
Takeshi Katsura said: “Because workers are hired through subcontractors, wages are skimmed all along the way, and workers at the bottom actually doing the work sees their pay go down.” “For people in Japan who live like me and work various places, it’s hard to find work that pays $100 a day,” nuclear gypsy Tanaka said. “I get housing, and was able to save more than usual.”
But the promise does not deliver. “The government says it will pay $100 a day, but I initially got $20,” said Sato, another worker lured to Fukushima by the promise of extra cash. “The contractors and subcontractors took the remaining $80.”
In December 2013 a Reuters Special Report noted that only a third of the money allocated for wages made it to the workers. The rest was skimmed by middlemen, police reports say. After deductions for food and lodging, that left workers with an hourly rate of about $6, just below the minimum wage equal to about $6.50 per hour in Fukushima. Some of the homeless men ended up in debt after fees for food and housing were deducted, police say.
The report noted that the problem of paid workers running into debt is widespread. “Many homeless people are just put into dormitories, and the fees for lodging and food are automatically docked from their wages,” said a Baptist pastor and advocate for the homeless. “Then at the end of the month, they’re left with no pay at all.”
The base pay for decontamination work may in theory be higher than for other kinds of work. But the risks are also higher.
In a January 2014 Al Jazeera Special Report, nuclear gypsy Tanaka says he was shocked to find radioactive hot spots in the area he worked, marked with tape but never decontaminated. Training and protective gear were also scarce. “The training didn’t teach us the dangers of handling radiation, so there were some people who worked with their bare hands,” he said. “They would contaminate not only themselves, but would spread particles to others.
Tanaka was fired after his company’s contract wasn’t renewed. Like many nuclear workers approaching their radiation limit of 50 millisieverts a year, it is unlikely that Tanaka will ever be hired at Fukushima again. He’s since lost his apartment, and is crippled by fatigue.
When Sato, another nuclear gypsy, complained about the terms of his employment, he was told his contract had changed, and that he now owed money for food and lodging. Sato was lucky. Others who complain and quit like him have faced violent retribution.
“I’ve had workers tell me that they’ve been beat up and been told, ‘I’ll kill you,’” said Katsura. “Threatened with, ‘You know what will happen to you.’”
Radiation Exposure: Unclear Rulings, Erratic Enforcement
Mainichi Japan’s report in March 2015 on the decontamination project noted that about 28,000 people per day were hired to do decontamination work in 2014, according to the Ministry of the Environment and the Fukushima Prefectural Government. This year the figure has reached about 20,000. But their status regarding radiation exposure remains unclear.
It is also far from clear who is to take responsibility for management of radiation doses, one observer has reported.
In January 2012, an act came into force which gave decontamination workers the same radiation exposure limits as nuclear power plant workers (a maximum of 50 millisieverts per year and 100 millisieverts over five years). This act specified that employers must have their workers undergo special health checks, and they must record and preserve their radiation readings.
However, at the time the regulation came into effect, there was no centralized system for managing individual workers’ total radiation exposure.
Furthermore, sloppy implementation, a lack of oversight, and the very existence of a floating population of itinerants, nuclear gypsies, have made this regulation difficult or impossible to enforce.
In a Mainichi Japan article on March 12, 2015 one 45-year-old man who has visited seven decontamination sites since October 2012 comments, “In decontamination by cities, towns and villages, there are areas called “microspots” where radiation levels are high even in areas being decontaminated by municipal governments.
Another observer, a 58-year-old man who applied to take part in managing decontamination work has offered the following summary on the vast project: “Decontamination has produced a temporary economic bubble, and all sorts of businesses have got in on it.” But it is not all good. “I get looked at as if I’m doing something dirty, and I think I’ve had enough of it,” he said.
Injuries and Deaths on the Job: TEPCO’s Response
To the argument frequently posed that nobody has officially died at Fukushima, a January 2015 report of rising numbers of onsite accidents and deaths, many of which have been attributed to poor onsite oversight or management, may offer a response.
Data released by TEPCO and reported in Mainichi Japan in March 2015 showed that the number of accidents and cases of heat stroke involving Fukushima workers had doubled to 64 in 2014
The pattern is very Japanese. Incident, charges, apology or faux explanation, inaction, another incident. More apologies. No change in hiring, pay, working conditions.
A cosmetic change – opening a workers’ canteen.
ENENEWS reported on January 20, 2015 on injuries and fatalities. The number of incidents doubled this year. “It’s not just the number of accidents that has been on the rise. It’s the serious cases, including deaths and serious injuries that have risen…” said Katsuyoshi Ito, a local labor inspector overlooking the Fukushima power plant.
ENENEWS reported that the number of injured workers has soared at Fukushima No. 1 nuclear plant [and] far exceeded the 2013 figure by November 2014, [TEPCO] officials said… Thirty-nine workers were injured at the plant between April and November 2014, while one became ill.
Last Sept. 22, a worker from a partner compan suffered a broken back after being hit by a falling iron pipe. During work to build a tank on Nov. 7, three workers were injured by falling steel weighing 390 kg. One was left temporarily unconscious, while another broke both ankles. Labor inspectors recently warned [TEPCO] about the rise in accidents and ordered it to take measures to deal with the problem.
Akira Ono, the head manager of the Fukushima Daiichi plant said: “We are deeply sorry for the death of the worker and express our deepest condolences to the family. We promise to implement measures to ensure that such a tragedy does not occur again.”
Fukushima Diary reported on a new fatality. On August 3, 2015 TEPCO reported that another Fukushima worker had died 2 days before. Although TEPCO states the cause of death is not identified, a former Fukushima worker posted on Twitter that the worker died of heatstroke.
It is speculated that TEPCO withheld the announcement of the death so as not to cause a scandal before removing debris from the fuel handling machine from 3 (Spent Fuel Pool of Reactor 3).
TEPCO’S Response to Labor Complaints: On June 24, 2015, a few months after the dispute with the labor inspectors and a full four years after the three part disaster 3/11, Reuters reported that TEPCO has opened a rest area and canteen for cleanup workers, which will serve up to 3,000 meals a day and provide rest space for around 1,200 workers.
According to Reuters, TEPCO has been widely criticized for its treatment of workers and handling of the cleanup, which is expected to take decades. TEPCO has repeatedly promised to improve conditions for workers. Almost 7,000 workers, provided by around 800 mostly small contractors, are involved in decontaminating and decommissioning the plant.
Decontamination Project: Future Plans
Depending on whom you talk to, decontamination has either been very successful or a complete failure. The business is estimated to take at least another 40 years, so there will be no lack of job opportunities. Areas said to be decontaminated still register very high levels of radiation.
However, the project has not met with local approval. Most Fukushima folk displaced by the nuclear accident have said they do not believe the government’s assurances of safety and they are unwilling to return home.
In a July 21 2014 press release, a Greenpeace Japan investigation revealed that “Radioactive contamination in the forests and land of Imitate district in Fukushima prefecture is so widespread and at such a high level that it will be impossible for people to safely return to their homes.”
The press release noted that these findings follow the Abe Government’s announcement on 12th June 2015 to lift evacuation orders by March 2017 and terminate compensation by 2018, which effectively forces victims back into heavily contaminated areas.
Jan Vande Putte, radiation specialist with Greenpeace Belgium: “The Japanese government has condemned the people of Litate village to live in an environment that poses an unacceptable risk to their health. Stripping nuclear victims of their already inadequate compensation, which may force them to have to return to unsafe, highly radioactive areas for financial reasons, amounts to economic coercion. Let’s be clear: this is a political decision by the Abe Government, not one based on science, data, or public health,” he said.
Decontamination: Greenpeace’s Summary
It is possible that the people of Fukushima took note of Greenpeace’s July 21 2015 report. In July 2015, the administration of Prime Minister Shinzo Abe appeared to be taking a big step toward the goal of repatriating Fukushima evacuees by adopting a plan that would permit two-thirds of evacuees to return by March 2017, the sixth anniversary of the disaster.
But while some evacuees have cheered this chance to return, many more have rejected it. In fact, polls show a majority do not even want to go back.
In a telling move in a country where litigation is relatively rare, more than 10,000 have joined some 20 class-action lawsuits to demand more compensation so they can afford to choose for themselves whether to return.
The Abe government’s new timetable, adopted on June 12, calls for accelerating the pace of this cleanup with a “concentrated decontamination effort” over the next two years.
In Litate, the narrow valleys are filled with workers scraping off the top two inches of soil, which is then put into black bags that are stacked into man-made hills. Across the entire evacuation zone, workers have already filled 2.9 million bags, which will be stored for at least the next 30 years at toxic waste sites that the government is building inside the zone.
But even with the massive cleanup, only about one-fifth of the 6,200 displaced residents of Litate are willing to return, according to a recent head count by village officials.
To summarize the future of Japan’s nuclear decontamination program, perhaps the best commentary also comes from Greenpeace.
“Decontamination efforts are, many times, missing the government’s targets. Massive amounts of highly radioactive water flow into the ocean from the reactor site every day. The location of molten reactor cores in Units 1-3 remains unknown – which is a problem that requires massive amounts of cooling water every day to minimize the risk of another major radiation release.”
“Those who created the Fukushima Daiichi nuclear catastrophe know that their nuclear power plants have no place in a modern Japan. And they are fighting as hard as they can to stop clean energy progress and shore up their dirty-energy-based profits.”
“But, for the people of Japan, a majority of whom oppose any nuclear restart, there are massive opportunities on the horizon for a truly safe and clean future. And we, at Greenpeace, will stand with them – against the onslaught of the nuclear village – to ensure that the clean, renewable energy future becomes a reality.”

Tepco Restructures, Subdividing Non-Nuclear Concerns
Tokyo Electric Power Company in Japan said it was restructuring the company, creating three businesses that continue with its 2014 separation of its nuclear businesses from its non-nuclear concerns.
As from 1 April 2016, Tepco said, the company will spin off its fuel and thermal power generation business into a company called TEPCO Fuel and Power, Incorporated. Its distribution and transmission business will become TEPCO Power Grid Incorporated. Its retail electricity business will be spun off as TEPCO Energy Partner Incorporated.
Tepco said it was making the major structural changes to survive in the post-Fukushima Daiichi reality. The new brand “signifies [the company’s] … determination to survive in the midst of competition while fulfilling its responsibilities for the Fukushima nuclear accident,” the company said.
“Japan’s electricity market is entering a period of dramatic change. Full liberalization of the electricity retail market is scheduled for April 2016, and the law requires separation of electricity transmission and distribution functions from the retail business in 2020.
“The changes in TEPCO’s company structure anticipate these changes and prepare it to succeed in the new, competitive environment, while serving its customers with a stable supply of electricity and full retention of its responsibilities not only for Fukushima but also for safety and reliability throughout its business,” the company said in a statement.
The company has already been effectively nationalized in the post-Fukushima era. The company’s 10-year plan allowed the government 51 percent of the company in exchange for $8 billion in government funding. Last year, in 2014, it restructured to form a separate division that would focus on decommissioning at the Fukushima Daiichi power plant where three reactors suffered meltdowns after a tsunami event that followed the March 11, 2011 Great East Japan Earthquake.

Underground temperature never go down regardless of frozen wall beside common fuel pool
The underground temperature beside common fuel storage pool has not been decreased since the end of April from Tepco’s report released on 8/20/2015.
Tepco is testing the frozen underground wall to circulate the coolant material in the frozen duct.
They have been monitoring the temperature at 18 points around the crippled reactor buildings.
From their data, the temperature of the monitoring point “No.12″ is showing almost no decrease from the beginning.
This is located between Reactor 4 building and the common pool, where is stocking the fuel assemblies removed from SFP 4 (Spent Fuel Pool in Reactor 4). At the moment of 8/20/2015, it is still over 10 ℃.
For some reason, Tepco stopped sending the coolant material to 4 of the monitoring points.
Among the rest of the points, the temperature is still above 0 ℃ at 8 of 14 monitoring points.
Fukushima operator’s mounting legal woes to fuel nuclear opposition
Four and a half years after the Fukushima disaster, and as Japan tentatively restarts nuclear power elsewhere, the legal challenges are mounting for the crippled plant’s operator.
IWAKI, Japan: Four and a half years after the Fukushima disaster, and as Japan tentatively restarts nuclear power elsewhere, the legal challenges are mounting for the crippled plant’s operator.
They include a judge’s forced disclosure of a 2008 internal document prepared for managers at Tokyo Electric Power Co warning of a need for precautions against an unprecedented nuclear catastrophe.
Also, class actions against Tepco and the government now have more plaintiffs than any previous Japanese contamination suit and, overruling reluctant prosecutors, criminal charges have been levelled against former Tepco executives for failing to take measures to prevent the 2011 meltdowns and explosions.
Radiation from the worst nuclear disaster since Chernobyl in 1986 forced 160,000 people from their homes, many never to return, and destroyed businesses, fisheries and agriculture.
The criminal and civil legal cases do not threaten financial ruin for Tepco, which is now backstopped by Japanese taxpayers and faces far bigger costs to decommission the Fukushima plant and clean up the surrounding areas.
Rather, the cases could further increase opposition to nuclear restarts – which consistently beats support by about two-to-one – as Prime Minister Shinzo Abe’s government pushes to restore nuclear to Japan’s energy mix to reduce reliance on imported fossil fuel.
“The nuclear plant disaster has upended our way of life,” evacuee and former beekeeper Takahisa Ogawa, 45, testified recently in a court in Iwaki, near the Fukushima power station. “We’ve lost the support we counted on.”
PROVING NEGLIGENCE
Ogawa and other plaintiffs are seeking 20 million yen (US$160,000) each in damages from Tepco. More than 10,000 evacuees and nearby residents have brought at least 20 lawsuits against the utility and the government over the handling of the disaster at the Fukushima Daiichi nuclear plant 220 km (130 miles) north of Tokyo.
The biggest class action, with 4,000 plaintiffs, seeks to dramatically increase Tepco’s liability by proving negligence under Japan’s civil law, rather than simply proving harm and seeking compensation, said lead attorney Izutaro Managi.
Japan recently approved increasing the amount of compensation payments through a government-run fund to 7 trillion yen (US$56 billion).
Prosecutors twice declined to charge former Tepco bosses over their handling of the disaster, citing a lack of evidence, but a citizens’ panel overruled them last month. It’s unlikely the three former executives, who will be summoned to give evidence in court, will be convicted as it is hard to prove criminal acts in this type of case, said Nicholes Benes of The Board Director Training Institute of Japan.
A first trial is not expected to start until next year at the earliest.
The legal actions against Tepco are “serious for the industry” as it seeks to gradually bring some of Japan’s 43 idled nuclear reactors back online, said Tom O’Sullivan, an independent energy consultant and former investment banker.
“With potentially up to 25 reactors coming online, board members of other electric power companies must be quite nervous about what could happen if something goes wrong,” he said. “Most reactors have been switched off for four years so switching them back on is going to be potentially problematic, not to mention the risk of natural disasters.”
“UNAVOIDABLE”
It’s unclear what bearing the various lawsuits against Tepco might have on one another, but a common thread is that it should have anticipated the possibility of a devastating quake and tsunami and taken steps to reduce the impact.
The company maintains that the severity of the 9.0 magnitude quake and 13-meter wave could not have been predicted.
But the document introduced as evidence in the shareholders’ suit after a judge forced Tepco to produce it, appears to challenge that. The “Tsunami Measures Unavoidable” report, dated September 2008, was filed with the Tokyo District Court in June, but has not been widely reported.
The unnamed authors prepared the report for a meeting attended by the head of the power station and marked the document “to be collected after discussion.” It’s not clear whether senior executives in Tokyo saw the report at the time.
The report called for Tepco to prepare for a worse tsunami than it previously assumed, based on experts’ views.
“Considering that it is difficult to completely reject the opinions given thus far of academic experts on earthquakes and tsunami, as well as the expertise of the (government’s) Headquarters for Earthquake Research Promotion, it is unavoidable to have tsunami countermeasures that assume a higher tsunami than at present,” says the report.
“This is prime evidence that Tepco recognised the need for tsunami measures,” said Hiroyuki Kawai, lead attorney in the shareholders’ suit. “This will have an important impact on the lawsuit.”
Tepco, in a court filing, counters that the document “does not mean there was a risk that a tsunami would strike and did not assume any specific tsunami countermeasures.”
Asked to comment further on the internal report and the range of legal problems facing the company, Tepco spokesman Kohji Sakakibara told Reuters, “We cannot answer these questions because they pertain to lawsuits and because they suppose a hypothetical determination of negligence. However, the company is making appropriate assertions in the lawsuits and expects that in the end the courts will render fair judgements.”
The shareholder lawsuit, filed in March 2012, seeks to establish responsibility for the disaster and demands 5.5 trillion yen (US$44 billion) in damages from current and former executives. A verdict is not expected for at least a year.
“This is likely to become a long battle where lawsuits go on for several decades or half a century,” said Shunichi Teranishi, a professor emeritus of environmental economics at Hitotsubashi University in Tokyo, comparing it to the Minamata mercury poisoning disaster in the 1950s, where lawsuits continue to be filed to this day.

Tepco readies to install unit 3 cover
From World Nuclear News, a pro-nuclear website
The installation of a protective cover over unit 3 of the damaged Fukushima Daiichi plant in Japan can start as soon as the removal of rubble from the reactor building is completed, Tokyo Electric Power Company (Tepco) said.
Plans were announced in November 2012 for a cover to be constructed to encase the unit’s damaged reactor building, protecting it from the weather and preventing any release of radioactive particles during decommissioning work.
The section of the reactor building that sheltered the service floor of unit 3 was wrecked by a hydrogen explosion three days after the tsunami of March 2011 – leaving the fuel pond exposed and covered by debris including many twisted steel beams.
The fabrication of the cover has been under way since November 2013 at the Onahama works in Iwaki city. It has been made in sections so that once it is transported to Fukushima Daiichi, the time to assemble it can be shortened and the radiation exposure to the workers on site can be significantly reduced, Tepco said.
A separate structure will be built to facilitate the removal by crane of used fuel from the storage pool. This 54-metre-tall structure will include a steel frame, filtered ventilation and an arched section at its top to accommodate the crane. Measuring 57 metres long and 19 metres wide, it will not be fixed to the reactor building itself, but will be supported on the ground on one side, and against the turbine building on the other.
On 2 August, Tepco announced that it had removed the fuel handling machine, the largest remaining piece of rubble, from the unit’s used fuel pool at the top of its reactor building. Its removal followed months of preparation and clears the way for the remaining rubble and the used fuel in the storage pool to be removed.
The assembly of the protective cover over unit 3 will start once all the rubble is removed.
Tepco said there are a total of 566 fuel assemblies inside the unit’s pool and the cover will prevent radioactive substances from scattering during their removal.
The fuel removed from unit 3 will be packaged for transport the short distance to the site’s communal fuel storage pool, although it will need to be inspected and flushed clean of dust and debris.

Is the Pacific Ocean Japan’s private dumpyard?
An article coming from the Yomiuri Shimbun, a pro-government media, its director and Prime Minister Abe are very best friends.
Read between the lines, funny enough the title says it all: the most important part of the Tepco Fukushima Daiichi decommissioning plan is to be able to dump as much contaminated water as possible into the Pacific Ocean.
Mind you Tepco has been already doing that all along since the beginning, but in a sneaky manner. With the now obtained approval of the Fukushima Prefectural Federation of Fisheries Cooperative Associations, Tepco will be able to do it in the open and in a grand manner.
Mind you, what Tepco calls decontaminated water, is contaminated water which has been only partially decontaminated, as the two decontamination systems Alps and Kurion can only filter, remove, 62 radionuclides out of the 1270 radionuclides present in that contaminated water.
This confirms what we already knew of Tepco’s intentions, somehow Tepco and the Japanese Government since day one have been considering our Pacific Ocean to be their contaminated water private dumpyard.
Why other countries of the Pacific region are not protesting against this constant radioactive water duumping which has been ongoing now for more than 4 years?
Release of treated water into sea a step toward Fukushima decommissioning
A solid step has been taken toward the decommissioning of the reactors at Tokyo Electric Power Co.’s Fukushima No. 1 nuclear power plant.
The Fukushima Prefectural Federation of Fisheries Cooperative Associations has approved TEPCO’s plan to release water into the ocean after it has been decontaminated.
Under the plan, TEPCO will pump up water from wells, called subdrains, around reactor buildings at the plant. This water will then be treated and discharged into the sea. There are expectations that this will reduce the volume of contaminated water generated when groundwater accumulates inside buildings wrecked by the March 11, 2011, earthquake and tsunami.
As preconditions for accepting the subdrain plan, the prefectural fisheries federation listed five demands, including improving public channels of information regarding the plan’s stringent water management and safety. These conditions were set out of the federation’s concern about groundless rumors surrounding the plan. TEPCO must sincerely handle these demands and ensure the water release plan is translated into action soon.
Regarding water quality management, TEPCO plans to set a stringent goal of cleaning the water to a level that exceeds international standards for drinking water. It is conducting water purification tests using a special-purpose treatment system. We hope the utility will release this data and carefully explain the system to clear up any anxiety felt by the public.
Initially, the volume of groundwater seeping into the buildings at the nuclear plant reached about 400 tons a day.
Since May 2014, TEPCO has been pumping up groundwater from other wells on the hill near the plant and releasing it into the sea before it flows into the buildings and becomes contaminated. This process has reduced the daily volume of water entering the buildings to about 300 tons a day.
TEPCO believes realization of the plan to pump water from the subdrains and discharging it into the sea after treatment could halve the volume of water entering the wrecked buildings to about 150 tons per day.
Undoubtedly, this will significantly reduce the labor required for managing contaminated water at the plant.
A boost for ‘ice wall’
The fisheries federation stated that the reduced risk of ocean contamination was one reason for its decision to give the green light to the plan.
An impermeable wall has been built along the port in front of the wrecked plant to prevent contaminated water from reaching the sea. The wall contains an opening about 10 meters wide, so it is not completely closed off. The federation viewed the flow of contaminated water through this opening into the port as a problem.
This opening was left because completely blocking off the groundwater would have the effect of a dam, and the water level behind it would rise. There were fears this would increase the volume of water entering the buildings.
By pumping up groundwater through the subdrains, the impermeable wall can be sealed off and any rise in the water level can be prevented. This should help to dispel groundless rumors.
There are also expectations that pumping up groundwater and reducing the water level will enable greater progress in TEPCO’s construction of an “ice wall,” in which soil around the reactor buildings will be frozen to stop groundwater from entering the buildings.
However, even after treated water is discharged into the sea, contaminated water will continue to accumulate. A veritable forest of about 950 large tanks, which combined hold about 690,000 tons of water, already stands within the plant’s premises. Sooner or later, it will become difficult to secure space to install any more tanks.
Purification of the water stored in these tanks is progressing steadily. At some point, discharging this water into the sea also will need to be considered.

Why are Radioactive Emissions Increasing at Fukushima Daiichi?
Fukushima Daiichi continues to contaminate the atmosphere with radionuclides. TEPCO acknowledged in July of 2012 that units 1 through 4 at the plant were emitting approximately 10,000,000 Bq per hour.[i]
It appears as if emission levels have increased since 2012. According to documents interpreted by Fukushima Diary, TEPCO asserted May 25, 2015 that ongoing emissions were estimated at a rate of 2,336,000,000 Bq per hour of noble gas and 960,000 Bq per hour of of Cs-134/137.[ii]
Fukushima Diary pointed out that Reactor 3 emissions increased over 2014. Reactor 4’s emissions were reported as 95,000 Bq/hour of Cesium134/137 despite TEPCO’s reported success in removing rods from unit 4.Why?
Why are atmospheric emissions rising and what does it mean for climate change? Please see discussion here: http://majiasblog.blogspot.com/2015/07/strangely-missing-radionuclides-effects.html

Fukushima fishermen give nod to TEPCO’s plan to release treated water into sea
Fisherman operating in waters close to the stricken Fukushima No. 1 nuclear power plant formally approved a plan by plant operator Tokyo Electric Power Co. to discharge radioactive groundwater into the ocean after decontamination treatment.
The Fukushima Prefectural Federation of Fisheries Cooperative Associations gave the green light to TEPCO’s “subdrain plan” at an extraordinary meeting on Aug. 11.
TEPCO is expected to start discharging treated water as early as next month.
It will pump contaminated groundwater accumulating in areas around reactors damaged by the March 2011 earthquake and tsunami disaster for processing and then release it into the sea.
The fishermen’s federation submitted a written request to the central government and TEPCO setting certain conditions for giving its approval to the subdrain plan. It warned the utility against discharging highly radioactive water inside the reactor buildings even after decontamination treatment and called for strict monitoring of standards for the release of water. It also insisted on compensation in the event the local fishing industry suffers losses as a result of groundless rumors.
Many fishermen initially opposed the TEPCO plan as processed radioactive water had never been discharged into the ocean.
TEPCO’s delay in disclosing the leakage of radioactive water into the sea each time it rained heavily also hampered its negotiations with local fishermen as it undermined their confidence in the company. The matter only came to light in February.
TEPCO then made an intensive effort to explain the subdrain plan would help reduce the flow of contaminated underground water into the ocean. This convinced the prefectural fishermen’s federation that the work could drastically decrease radiation levels in nearby waters, prompting it sign off on the plan.

EDITORIAL: Trials of ex-TEPCO bigwigs a chance to take fresh look at disaster
The Fukushima No. 1 nuclear power plant is hit by tsunami on March 11, 2011.
Three former executives of Tokyo Electric Power Co. will stand trial over their criminal responsibility for the 2011 disaster at TEPCO’s Fukushima No. 1 nuclear power plant.
For the second time, the Tokyo No. 5 Committee for the Inquest of Prosecution has rejected an earlier decision by prosecutors not to indict the three, setting the stage for the forced prosecution of these three individuals.
They will be accused of professional negligence resulting in the deaths of people who were in hospitals when the disaster happened and other tragedies.
A report issued by the Diet’s Fukushima nuclear accident investigation committee states, “It is clear that the accident was a man-made disaster.”
But no government officials or TEPCO employees have been punished, either politically or administratively. In other words, no one has been held accountable for the nation’s worst nuclear accident.
Many Japanese citizens still feel that justice has not been meted out with regard to that harrowing disaster. Many are also concerned that a similar accident may occur again if nobody is held responsible for what happened in 2011.
A second decision by the independent judicial panel of citizens to demand the criminal prosecution of the three former TEPCO executives should be viewed as indicative of the disturbing and disquieting feelings among many citizens.
The system of forced indictment through the judgment of citizens was introduced in 2009, along with the “saiban-in” citizen judge system. Until that time, public prosecutors monopolized the power to decide whether to indict a suspect. The new system is intended to ensure that public opinion is reflected in the process of criminal prosecution, at least to a certain degree.
In reversing public prosecutors’ decision not to indict the suspects on grounds that there is no compelling case for holding them liable for negligence, the panel of citizens made a grave decision to force trials of the three individuals.
The court should, of course, consider carefully and fairly whether the former TEPCO executives should be held liable for the misfortunes of disaster victims from the viewpoint of evidence submitted.
At the same time, one question that needs to be asked is how TEPCO implemented measures to protect the nuclear plant from a possible tsunami and ensure the plant’s safety.
Collectively, the trials will offer a great opportunity to take a fresh look into the accident from a perspective that is different from those of the investigation committees set up by the government and the Diet.
There have not been many opportunities for people to talk about the disaster in public. But the three former TEPCO executives will probably be given opportunities to speak in the courtroom. The court can also order submission of specific pieces of evidence.
Future public debate on issues concerning nuclear power generation will benefit greatly if the trials uncover unknown facts in the process, such as chronological changes in the utility’s decisions concerning safety measures for its nuclear power plants and the ways the government and other public organizations influenced the company’s policy.
The nation’s judiciary has a long history of handing down rulings related to nuclear power generation. But in most of the past cases concerning the construction and operations of nuclear power plants, the courts ruled against opposing local residents.
The question is whether all these court rulings in favor of nuclear power were influenced in any way by the perception that there is no way to stop the expansion of electricity production with atomic energy based on the government’s energy policy.
The judiciary’s attitude to nuclear power generation has also been called into question by the accident.
In considering the criminal liabilities related to the Fukushima nuclear disaster, which has caused an unprecedented scale of damage, are the traditional criteria, like “specific predictability,” sufficiently effective?
The trials should prompt the judicial community to have more in-depth debate on this question.
We strongly hope the trials will be conducted in a way that lives up to people’s confidence in the judicial system.

Judicial review panel votes to indict ex-Tepco execs
(Left to right) Former Tepco Chairman Tsunehisa Katsumata and former vice presidents Sakae Muto and Ichiro Takekuro.
Three former top executives at Tokyo Electric Power Co. are set to be hauled into court over their alleged responsibility for the 2011 Fukushima nuclear crisis.
The Tokyo No. 5 Committee for the Inquest of Prosecution voted Friday that Tsunehisa Katsumata, chairman of Tepco at the time of the disaster, and two former vice presidents, Sakae Muto and Ichiro Takekuro, should be indicted for professional negligence resulting in death and injury.
The announcement by the panel of citizens came more than four years after the massive tsunami of March 11, 2011, knocked out the critical cooling functions at Tepco’s Fukushima No. 1 plant, leading to three of the six reactors there melting down.
Prosecutors have twice previously decided not to seek such indictments, saying Tepco could not have expected such a massive tsunami to hit the nuclear plant and cripple its critical safety systems.
But on Friday the committee overrode the prosecutors’ decisions for a second time, which will lead to a compulsory indictment of the three Tepco executives. They were all responsible for major disaster prevention planning.
Holding a news conference at the Tokyo District Court, representatives of a group of Fukushima residents and others who have filed criminal complaints against the executives said they were elated.
“I want (the Tepco executives) to tell the truth” during the upcoming trials, said Ruiko Muto.
Muto said many elderly people who evacuated from the radiation-contaminated areas have since died in shelters away from their hometowns, while numerous people still living in Fukushima are being exposed to radiation via contaminated materials from the heavily damaged plant.
Muto said many people outside the prefecture have the impression that the nuclear crisis is over.
“If who should be held responsible is not made clear, (the dead) victims won’t rest in peace,” she added.
Before the catastrophe, Tepco had conducted simulations and concluded that critical facilities at Fukushima No. 1 would be flooded and critically damaged if a major earthquake struck off the Tohoku coast and tsunami of more than 10 meters in height hit the plant.
But prosecutors concluded that it was impossible for Tepco to predict such gigantic tsunami would actually hit the plant, as opinions from quake experts were not established regarding the possibility of such a powerful quake.
The judicial review committee said the Tepco executives were obliged to prepare for a worst-case scenario even if the possibility of such a disaster was considered very small.
The simulations provided a good indication that a major crisis was possible, but the three neglected their obligation to prepare for such an eventuality, the committee concluded in a 30-page document explaining its decision.
The panel pointed out that 44 patients who were forced to evacuate from a hospital located 4.5 km from Fukushima No. 1 died after their health conditions deteriorated because of the move. The committee alleged that their deaths were caused by the meltdown crisis.
Meanwhile, no health damage has so far been confirmed to have been caused by radiation from contaminated materials released from the plant.
The committee said one person who was exposed to radiation from contaminated materials has been diagnosed with thyroid cancer, but a causal link with the meltdown disaster has not been established.
The central government is preparing to allow the reactivation of some commercial reactors suspended in the wake of the Fukushima crisis.
Muto said she hopes the findings in the upcoming trials will prompt a change in the national nuclear policy and lead to the abolition of all nuclear power plants.

Three former TEPCO executives to stand trial – Residents hail indictment decision
Three former TEPCO executives to stand trial
Three former executives of Tokyo Electric Power Company will face mandatory indictment over the March 2011 nuclear accident at the Fukushima Daiichi plant.
Nobody has been held criminally responsible so far for Japan’s worst nuclear accident.
The prosecution inquest panel of randomly-selected citizens voted for the indictment on Friday, disagreeing for a 2nd time with prosecutors who had dismissed the complaint filed against the officials. The prosecutors said the officials could not have predicted a quake and tsunami on the scale of the March 11th disasters.
The decision leads to the mandatory indictment of former TEPCO chairman Tsunehisa Katsumata and former vice presidents Sakae Muto and Ichiro Takekuro for professional negligence resulting in death and injury.
Court-appointed lawyers will act as prosecutors in the trial.
In its decision, the panel said TEPCO should have taken measures to protect the plant from tsunami and flood-triggered serious accidents after it had made a projection of a 15.7-meter tsunami hitting the plant.
The panel said TEPCO could have foreseen that in a worst-case scenario, flooding would result in a massive release of radioactive substances or other severe situations. The panel said that if TEPCO had taken appropriate precautions, a serious accident like the one in March 2011 could have been avoided.
Prosecutors in 2013 dismissed the initial complaints filed by Fukushima residents and others against more than 30 former TEPCO officials for failing to take precautions against major quakes and tsunami.
The case was taken up for reconsideration by the inquest panel, which decided in July last year that the three officials should be indicted.
But prosecutors dismissed the case again in January, sending it back to the inquest panel.

Residents hail indictment decision
The leader of the residents, Ruiko Muto, has praised the panel’s decision.
Muto said she believes a court will determine who was responsible for the 2011 Fukushima nuclear disaster and give a fair judgment.
She said that 110,000 people are still unable to return to their homes. She added that having the former executives face a criminal trial will help prevent a recurrence and create a society in which people can live in peace.
The residents’ lawyer, Hiroyuki Kawai, also said that if the former officials had escaped indictment, the real cause of the accident would have been covered up forever.
He expressed hope that the trial will find out more about what caused the nuclear accident.
TEPCO declined to comment on the decision or the criminal complaint that led to it.
But it said in a statement that it wants to renew its heartfelt apology to the people of Fukushima and many others for causing trouble and concern.
The firm said it will do its utmost for compensation, plant decommissioning and decontamination, based on the principle of seeking reconstruction of Fukushima. It added that it is fully resolved to improving the safety of nuclear power plants.

Robot probe into No.2 reactor may be delayed
The operator of the crippled Fukushima Daiichi nuclear plant says it may have to postpone plans to send a robot probe into the plant’s No.2 reactor due to difficult preparations.
Tokyo Electric Power Company was planning to send a robot into the containment vessel of the No.2 reactor in August. The purpose is to capture video images of molten nuclear fuel for the first time.
The utility assumes the fuel penetrated the reactor core and is inside the containment vessel.
The plan involved using a pipe sticking out of the container as an entry point for the robot. But some concrete blocks are blocking the way and need to be removed.
Workers found that the remote-controlled machinery they wanted to use to remove the blocks cannot operate in some areas of the reactor building due to an eroded floor and other reasons.
TEPCO says it is now considering using chemicals to clear the blocks or developing new machinery to remove the blocks.
Due to these reasons, the utility says the probe may be postponed from August until December or later, in the worst case.
