Under the new policy, Japan will maximize the use of existing reactors by restarting as many of them as possible and prolonging the operating life of aging ones beyond a 60-year limit. The government also pledged to develop next-generation reactors.In 2011, a powerful earthquake and the ensuing tsunami caused multiple meltdowns at the Fukushima Daiichi plant — a disaster that supercharged anti-nuclear sentiment in Japan and at one point led the government to promise to phase out the energy by around 2030. But since then, the government has recommitted to the technology, including setting a target for nuclear to make up 20-22% of the country’s energy mix by the end of the decade.
Biden Administration Tramples on Japan’s Post-World War II Pacifist Constitution By Pushing Country’s Rearmament
Covert Action magazine, By Sara Flounders, January 9, 2023
Main target is China in dangerously provocative policy that faces no visible domestic opposition in the U.S.
On December 16, Japan’s Prime Minister Fumio Kishida announced a new defense strategy that doubled Japan’s military spending by 2027. Japan further agreed to acquire offensive weapons and reshape its military command structure for its expanded armed forces.
On December 23, the draft budget was approved by Kishida’s cabinet.
Japan’s dangerous military expansion should set off international alarm bells. This major escalation is taking place based on intense U.S. imperialist pressure. It is the next step in the “Pivot to Asia,” aimed at threatening and surrounding China and attempting to reassert U.S. dominance in the Asia Pacific.
The movements opposing endless U.S. wars must begin to prepare material and draw mass attention to this ominous threat.
The plan to double military spending will add $315 billion to Japan’s defense budget over the next five years and make Japan’s military the world’s third largest, after the U.S. and China. Defense spending will escalate to 2% of gross domestic product, equal to the goal the U.S. sets for its NATO allies. Japan’s economy is the world’s third largest.
The Japanese government plans to buy up to 500 Lockheed Martin Tomahawk missiles and Joint Air-to-Surface Standoff Missiles (JASSM), procure more naval vessels and fighter aircraft, increase cyber-warfare capabilities, manufacture its own hypersonic guided missiles and produce its own advanced fighter jets, along with other weapons. The plan shifts from relying solely on missile defense to also embracing “counter strike” capabilities.
………………………………………………… Although the U.S. occupation force, after defeating Japan’s military in World War II, imposed a “pacifist” constitution on Japan, for decades U.S. strategists have pressured Japan’s government to aggressively rearm, to buy U.S.-made weapons, and to act as a junior partner to U.S. efforts to dominate the Asia-Pacific region.
Article 9 of the imposed Japanese constitution prohibits Japan from maintaining an army, navy and air force. To get around this, the “Japanese Self-Defense Forces” (JSDF) have since 1952 been treated as a legal extension of the police and prison system. The U.S. occupiers considered the JSDF an essential repressive tool defending capitalist property relations against the workers’ movement.
The decision for aggressive military expansion is in open violation of Japan’s supposedly pacifist constitution………………………………………….
The present doubling of the defense budget will be funded by raising taxes. A huge military budget will inevitably mean severe cuts to the country’s limited social spending. ………………….
Targeting China
Japan’s military expansion fits in with Washington’s aggression aimed at China, the DPRK and Russia. U.S. strategists’ goal is to use the U.S. alliance with Japan, South Korea and Australia, just as it uses the U.S.-led NATO alliance in Europe……………………………..
China is Japan’s largest trading partner in both imports and exports. Previous National Strategy Documents said Japan was seeking a “mutually beneficial strategic partnership” with China. Suddenly Japanese strategists started labeling China “the greatest strategic challenge in ensuring the peace and security of Japan.” (U.S. Institute of Peace, December 19)………….,………
A U.S.-Japan alliance is now defined as a “cornerstone” of Japan’s security policy. (Japan Times, December 17)
U.S. Praise of Japan’s Rising Militarism
The U.S. media praised Japan’s new security strategy document as a “bold and historic step.” U.S. National Security Adviser Jake Sullivan praised the defense spending hike, which “will strengthen and modernize the U.S.-Japan alliance.” U.S. Secretary of State Antony Blinken called Japan an “indispensable partner” and cheered that the changed security documents reshape the ability to “protect the rules-based order in the Indo-Pacific region and around the world.” (quotes, whitehouse.gov, December 16)
U.S. corporate power is the immediate beneficiary of this sharp turn in policy, built on military threats and economic sanctions. …………………………………………………… more https://covertactionmagazine.com/2023/01/09/biden-administration-tramples-on-japans-post-world-war-ii-pacifist-constitution-by-pushing-countrys-rearmament/?mc_cid=8da2f4a668&mc_eid=65917fb94b
Japan and USA to develop small nuclear reactors”within each country and third countries.”
Japan and the United States agreed Monday to strengthen bilateral
cooperation on developing next-generation nuclear reactors during
ministerial talks on energy.
Japanese industry minister Yasutoshi Nishimura
and U.S. Energy Secretary Jennifer Granholm also agreed during their
meeting that Tokyo and Washington will work more closely on securing
liquefied natural gas and other energy security matters.
According to a
joint statement, Japan and the United States will step up cooperation in
developing and constructing next-generation advanced reactors, including
small modular reactors, “within each country and third countries.” The two
governments already revealed a plan in October to work together on helping
Ghana introduce small nuclear reactor technology.

Japan to use Self-Defense Forces to guard nuclear power plants
Government thinks critical infrastructure could be targeted, as seen in Ukraine.
Nikkei Asia 4 Jan 23, TOKYO –– The Japanese government will task the country’s Self-Defense Forces with protecting critical infrastructure, such as nuclear power plants, as it plans to respond immediately if civilian facilities become the target of an attack………….
Attacks on critical civilian infrastructure are banned under the Geneva Conventions, which sets the ground rules for the conduct of war. Russia’s strikes have highlighted the need to develop a response.
In Japan’s National Security Strategy, which was approved by the cabinet in December, the government states that measures to ensure the safety of critical facilities will be taken, not only in the event of an armed attack but in the run-up to a crisis that does not lead to such an attack………… https://asia.nikkei.com/Politics/Japan-to-use-Self-Defense-Forces-to-guard-nuclear-power-plants
Reviving Japan’s nuclear power industry will not be easy
Jan 3, 2023
Japan is facing its most severe energy crisis in decades and wants to speed up the revival of its nuclear energy industry to reduce its dependence on imported fossil fuels.
But restarting more nuclear reactors remains controversial, more than a decade after the 2011 Fukushima disaster.
What does the government want?
All the country’s reactors were shut down for safety checks after the Fukushima meltdown, and there are currently 33 considered operable.
By mid-December, nine were generating electricity, meeting a target set by Prime Minister Fumio Kishida this summer to help counter energy shortages and cover around 10% of Japan’s winter power consumption.
The national nuclear safety watchdog has approved the restart of seven other reactors in principle, but such moves often face fierce opposition from local communities.
In August, Kishida called for these seven reactors to come online by summer 2023 and said Japan should also consider building next-generation nuclear reactors.
He also said authorities would discuss extending the service life of existing reactors beyond the current 60-year limit if safety can be guaranteed.
Before the Fukushima disaster, nearly a third of Japan’s power generation came from nuclear energy, but in the fiscal year to March 2022, the figure stood at around 7%.
The government is aiming for nuclear power to account for between 20% and 22% of electricity production by 2030, part of efforts to reach carbon neutrality by 2050.
What are the obstacles?
The success of these nuclear power ambitions lies with Japan’s independent Nuclear Regulation Authority (NRA), which must give a green light to the plans before they go ahead.
“It will be a challenge” to get existing reactors going again, because some have been “stalled for quite a long time,” said Tom O’Sullivan, a Tokyo-based energy consultant at Mathyos Advisory.
Bringing nuclear plants online could also be complicated by “nervousness about anti-terrorism issues,” he added, pointing to concerns around plants caught in Russia’s war in Ukraine.
“Given what’s happening with the Zaporizhzhia nuclear power plant in Ukraine, I think the NRA is probably more sensitive nowadays to potential terrorist attacks.”
Surveys show that reticence among the Japanese public toward a nuclear power revival has eased since the war in Ukraine triggered a steep rise in energy prices last year.
But opposition from people living near the plants will remain a sticking point, while reports of security breaches at one large plant in recent years have added to public unease, said analyst Hiroe Yamamoto of Moody’s Japan.
How quickly the government’s nuclear power revival hopes can become reality depends on local authorities but also Kishida’s popularity this year, said Nobuo Tanaka, chair of the Innovation for Cool Earth Forum steering committee.
The prime minister is currently “in trouble,” with his approval ratings dragged down last year by scandals, Tanaka said at a recent news conference.
So “just saying we need (more reactors online) because of high energy prices — this kind of argument may not be sustainable,” and the government must also address issues such as waste disposal, he said.

Nuclear plant hosts split over Japan’s reversed energy policy
An anti-nuclear rally is held near the prime minister’s office building in Tokyo on Dec. 16.
December 23, 2022
The government’s return to reliance on nuclear energy sparked both anger and joy among municipalities that host nuclear power plants.
The Fumio Kishida administration, in a sweeping reversal of the nation’s nuclear energy policy, says it intends to make “maximum use” of nuclear power to secure a stable energy supply and reduce greenhouse gas emissions.
“We are still struggling to rebuild our community,” said Hisato Iwamoto, a member of the Futaba town assembly. “The central government must have forgotten the Fukushima disaster.”
The town co-hosts the Fukushima No. 1 nuclear plant, which suffered a triple meltdown after the Great East Japan Earthquake and tsunami in March 2011.
Iwamoto’s family was forced to move from one place to another in the prefecture following the disaster.
In fact, all residents of Futaba were told to evacuate their homes.
As a member of the town assembly that had endorsed nuclear power, Iwamoto said he feels responsible.
“It had never occurred to us that an accident could happen at the plant because we constantly asked the central government and Tokyo Electric Power Co. to ensure the plant’s safety,” he said. “I now know there is no such thing as ‘absolutely safe’ no matter how advanced nuclear plants become in the future.”
Since the 2011 triple meltdown, Iwamoto has consistently sounded warnings that a serious accident could occur at any nuclear plant when he attended meetings of assembly members of municipalities hosting nuclear plants across the country.
But their reactions have been lukewarm, according to Iwamoto.
Iwamoto, 65, noted that politicians opposed to nuclear energy would have difficulty winning elections in areas whose economies rely largely on nuclear plants.
His father, Tadao, was a good example.
Tadao was first elected to the Fukushima prefectural assembly in 1971 and began activity opposing nuclear plants. That opposition resulted in three straight election losses since 1975.
Even in the 1979 election, which followed the Three Mile Island nuclear accident in the United States in March that year, he gained the least number of votes among candidates.
After he switched his position and accepted nuclear power, he was elected Futaba mayor. He served five terms at the post.
Evacuees from Futaba were allowed to return to live in their hometown in August.
But Futaba is now a far cry from what it used to be, said Iwamoto, who still lives in evacuation in Iwaki in the prefecture.
“Community ties have never been restored,” he said.
Ritsuko Yanai, a 44-year-old mother who evacuated to Aizuwakamatsu in the prefecture, said she suspects the central government is “trying to wipe the slate clean.”
She is from Okuma, the other co-host of the Fukushima No. 1 nuclear plant.
She fled the disaster with her 1-month-old son. Her parents’ home was dismantled to make space for and interim facility to store debris and waste from decontamination work.
There is no clue on when decommissioning of the plant will be completed. And the release into the sea of tons and tons of treated water stored at the plant is expected to begin in spring.
“The nuclear accident is not over yet,” Yanai said.
But in Mihama, a town hosting the Mihama nuclear plant in Fukui Prefecture, the central government’s decision on nuclear power was mostly welcomed.
The prefecture facing the Sea of Japan hosts 15 reactors, the most in the nation. Seven of them, including two prototype reactors and two reactors at the Mihama plant, are in the process of decommissioning.
“The central government finally took action,” said Jitaro Yamaguchi, a former mayor of the town. “Nothing can serve as an alternative to nuclear energy.”
Yamaguchi, who was Mihama mayor for 20 years until he stepped down in 2019, had lobbied Kansai Electric Power Co., operator of the Mihama nuclear plant, to build more reactors in the town, with a population of about 9,000.
His pro-nuclear power stance remained unchanged even after the Fukushima disaster.
“We need nuclear plants when we think about environmental issues and power supply,” he said. “They have benefitted the local economy.”
The Mihama nuclear plant is called the “heart” of the local economy, sending “blood” to every corner of the town.
More than half of the town’s initial budget of 8.6 billion yen ($65 million) for fiscal 2022 is funded by revenues from nuclear facilities.
Since retiring as mayor, Yamaguchi, 79, has served as head of an organization promoting nuclear power.
He said he is pleased with the government’s new policy to replace retired reactors with new units. Previous governments had refused to commit to such projects following the Fukushima accident.
The town now has better prospects for construction of brand-new reactors–and more money.
“Nuclear power plants are an integral part of the local industry,” he said. “They should be built seamlessly.”
But the town is not without opponents of new reactors as well as advocates for a shift to renewables.
“A nuclear plant is akin to a drug addiction that you cannot break,” said Teruyuki Matsushita, a 74-year-old assemblyman. “Once a huge sum of money from a nuclear project is poured in the town, you are increasingly less likely to give serious thought on how to build the future of the town.”

Japanese panel approves return to nuclear power as disaster memories fade
Dec 22, 2022
Prime Minister Fumio Kishida’s advisory panel approved a plan to extend the lifespans of nuclear reactors beyond 60 years and build new units to replace those that are decommissioned, reversing policies put in place after the Fukushima disaster in 2011.
The step reflects a shift in public opinion, as the import-reliant country struggles with the threat of blackouts amid Russia’s war in Ukraine and extreme weather. While massive demonstrations calling for the abolition of atomic power were a regular occurrence in the wake of the meltdowns, recent polls indicate growing support for restarting idled plants.
The government is aiming to present legislation to parliament during the next session to put the basic plan into action, Kishida told a meeting of his “green transformation” panel, which is made up mostly of business executives and academics, on Thursday. The proposal will be opened for public comment and could gain Cabinet approval by February, the Nikkei newspaper reported.
Japan is joining a global shift back to nuclear energy after the prices of natural gas and coal shot to records this year as Russia’s invasion of Ukraine upended markets. The Kishida administration is also turning to nuclear to help curb emissions and hit Japan’s 2050 net-zero target.
A survey by the Yomiuri newspaper in August found 58% in favor of restarting idled reactors, the first time a majority approved of the idea in that poll series since the question was initially posed in 2017. A separate survey by public broadcaster NHK earlier this month found 45% approved of the panel’s plan, while 37% opposed it.
The government still faces some opposition from local residents over nuclear restarts and lawsuits related to safety concerns still keep many reactors offline. Only a third of Japan’s operable reactors have restarted since the 2011 disaster.
After the Fukushima disaster, Japan swore to phase out nuclear power. But not anymore
The Fukushima Daiichi nuclear power plant is seen on March 17. Japan on Thursday adopted a new policy promoting greater use of nuclear energy to ensure a stable power supply amid global fuel shortages and reduce carbon emissions — a major reversal of its phaseout plan since the Fukushima crisis.
December 22, 2022
TOKYO — Japan adopted a plan on Thursday to extend the lifespan of nuclear reactors, replace the old and even build new ones, a major shift in a country scarred by the Fukushima disaster that once planned to phase out atomic power.
In the face of global fuel shortages, rising prices and pressure to reduce carbon emissions, Japan’s leaders have begun to turn back toward nuclear energy, but the announcement was their clearest commitment yet after keeping mum on delicate topics like the possibility of building new reactors.
Still, restart approvals for idled nuclear reactors have come slowly since the Fukushima disaster, which led to stricter safety standards. Utility companies have applied for restarts at 27 reactors in the past decade. Seventeen have passed safety checks and only 10 have resumed operation.
According the paper laying out the new policy, nuclear power serves “an important role as a carbon-free baseload energy source in achieving supply stability and carbon neutrality” and pledged to “sustain use of nuclear power into the future.” Prime Minister Fumio Kishida said he planned to get the Cabinet to approve the policy and submit necessary bills to Parliament.
As part of the new policy, the Economy and Industry Ministry has drafted a plan to allow extensions every 10 years for reactors after 30 years of operation while also permitting utilities to subtract offline periods in calculating reactors’ operational life.
The plan was endorsed on Wednesday by the Nuclear Regulation Authority, Japan’s nuclear watchdog. New safety inspection rules still need to be put into law and approved by Parliament.
The regulation authority’s commissioner, Shinichi Yamanaka, told a news conference the new safety rules requiring operational permits every decade after 30 years will be safer than a current one-time 20-year extension option for 40-year-old reactors. But experts cast some doubt on that.
Some experts question extending the lifespan of older reactors
Takeo Kikkawa, an economics professor at the International University of Japan and an expert on energy, said utility operators under the new policy could keep using old equipment instead of investing in new technology or renewables.
“Naturally, we should aim for newer technology and use it safely. Therefore, extending reactors’ lifespans is an undesirable move,” Kikkawa recently told a talk show.
Most nuclear reactors in Japan are more than 30 years old. Four reactors that have operated for more than 40 years have received permission to operate, and one is currently online.
Under the new policy, Japan will also push for the development and construction of “next-generation innovative reactors” to replace about 20 reactors now set for decommissioning.
Kenichi Oshima, a Ryukoku University professor of environmental economy and energy policy, said some of what the government calls “innovative” reactors are not so different from existing technology and that prospects for nuclear fusion and other next-generation reactors are largely uncertain and not achievable anytime soon.
Thursday’s adoption of the new policy comes less than four months after Kishida launched the “GX (Green Transformation) Implementation Council” of outside experts and ministers to “consider all options” to compile a new policy that addresses global fuel shortages amid Russia’s war on Ukraine and seeks to achieve carbon neutrality by 2050.
Japan’s nuclear energy goals may be out of reach
Nuclear energy accounts for less than 7% of Japan’s energy supply, and achieving the government’s goal of raising that share to 20-22% by 2030 will require about 27 reactors, from the current 10 — a target some say is not achievable. The new policy also does not help address imminent supply shortages because reactors cannot be restarted quickly enough.
While public opinion on nuclear energy has softened since Fukushima, opponents still argue atomic power is not flexible and not even cheaper than renewables when final waste management and necessary safety measures are considered — and that it can cause immeasurable damage in an accident.
Ruiko Muto, a survivor of the Fukushima disaster, called the new policy “extremely disappointing.” She added: “The Fukushima disaster is not over yet and the government seems to have already forgotten what happened.”
The regulation authority came under fire Wednesday after revelations by a civil group that a few of its experts had discussed details with industry ministry officials before the watchdog was officially asked to consider a rule change for aging reactors, despite their compulsory independence.
Prime Minister Kishida also said Thursday that the government will do more to find candidate sites for a final repository for high-level nuclear waste that Japan does not yet have. Preliminary studies have begun in two small towns in Hokkaido, angering some residents.
Now that the government has turned to promoting nuclear power, I would like you to see a photo book published that tells the history of opposition to the construction of the Onagawa Nuclear Power Plant. Valuable data that survived the disaster
After the accident at the Fukushima Daiichi Nuclear Power Plant, Muneyoshi Abe (right), a resident of Onagawa Town, Miyagi Prefecture, held a banner saying, “Let Fukushima be a lesson to us all. Muneyoshi Abe (right) holds up a flag with the slogan “Oppose Onagawa Nuclear Power Plant” (from the photo book “50 Years in the Town of Nuclear Power Plants”).
December 22, 2022
A photo book titled “50 Years in the Town of Nuclear Power Plants: Thinking about the Future from Onagawa” was published to document the struggle to stop the construction of Tohoku Electric Power Company’s Onagawa Nuclear Power Plant (Onagawa Town, Miyagi Prefecture, and Ishinomaki City). While the Kishida administration has been pushing for nuclear power, Mikiko Abe, 70, the editor of the book and a member of the Onagawa Town Council, says, “I would like people to come into contact with the faces and thoughts of the local residents who have been fighting for half a century against nuclear power plants. (Norio Noro)
The plan to build a nuclear power plant in Onagawa was announced in 1968, and the struggle against the plant by fishermen and others began. Mr. Abe returned to his hometown after graduating from Chuo University in 1975 and joined in the struggle led by his father, Muneyoshi, who ran a shipping agent. He was outraged when he saw police riot police raising their shields and beating him, and began filming with a camera.
In September 1976, women in kappo-gowns marching in a demonstration at the “Three Towns United to Absolutely Stop Onagawa Nuclear Power Plant” rally held in Onagawa (from the photo collection “50 Years in the Town of Nuclear Power Plants”).
Residents blocking an overnight bus carrying supporters to the prefectural government’s “nuclear power plant briefing,” a demonstration at sea on a fishing boat, and a request to protest Tohoku Electric Power Company…. Standing on the frontlines of the struggle, the film records their thoughts and actions in defense of “the sea is life.
In 1977, the Onagawa Fisheries Cooperative Association passed a resolution at an extraordinary general meeting to invite nuclear power plants to Onagawa. While opponents were celebrating when the only thing reported outside was the “rejection of the abandonment of fishing rights,” which had been decided at the same time, Mr. Abe took a picture of himself shouting, “We passed a resolution to invite the nuclear power plant, so don’t shout ‘Hooray!
Construction of Onagawa Nuclear Power Plant Unit 1 began in 1979, and commercial operation began in 1984. In 2008, when the opposition to the plant continued, a town official asked Mr. Abe to preserve the photos he had taken, saying, “The struggle against the plant is part of Onagawa’s history, so I want to preserve it.
Mikiko Abe
However, her house and the town hall were hit by the tsunami in the Great East Japan Earthquake of 2011, and her precious photos and CDs were lost. However, she was lucky enough to find the data on a CD she had given to an acquaintance in Sendai City, which was left on the computer of another friend. Teiji Wada, 70, a native of the town and the head of the publishing company Ichiyo-sha (Kita-ku, Tokyo), and others have been working together to compile a photo collection.
The book contains approximately 340 photographs, including those taken by Mr. Abe in the 1970s, when the struggle was fierce. The book also includes testimonies from fishermen and others who describe the situation at that time, the Great East Japan Earthquake, and other events.
On April 26, after the accident at TEPCO’s Fukushima No. 1 nuclear power plant, Mr. Abe stood with Mr. Soetsu at the site of their debris-strewn home. That day marked the 25th anniversary of the Chernobyl nuclear power plant accident in the former Soviet Union. On the momohiki that had washed ashore, he wrote “Let Fukushima be a lesson to you? and “All nuclear reactors must be decommissioned! and “All nuclear power plants must be decommissioned! Muneyoshi passed away in 2012 at the age of 86, following in his father’s footsteps.
The Kishida administration has announced a shift in nuclear power policy to promote nuclear power for the first time since the Fukushima accident. Furthermore, the administration has been touting nuclear power as a decarbonizing and effective countermeasure to global warming.
Mr. Abe said, “The large amount of wastewater emitted from nuclear power plants is 7 degrees higher than the temperature of seawater, and this will contribute to global warming. Decommissioning or building new reactors requires enormous amounts of energy and increases carbon dioxide emissions. How will radioactive waste be disposed of and managed? I hope that people will see the origin of the struggle against nuclear power and deepen their understanding of the need for nuclear power plant phase-out,” he said.

Bad move to prolong the life of an industry with no growth potential: Official Decision to Operate Nuclear Power Plants for More Than 60 Years, With the Goal of Restoring the Nuclear Power Plant Accident Unseen
Prime Minister’s Office
December 22, 2022
On the afternoon of December 22, the government will hold a meeting of the Green Transformation (GX) Council at the Prime Minister’s Office to discuss industrial transformation to realize a decarbonized society, and will formally decide on a basic policy that includes measures to utilize nuclear power plants, focusing on operating them for “more than 60 years” and rebuilding (replacing) them.
After the accident at TEPCO’s Fukushima Daiichi Nuclear Power Station in 2011, the government had legally limited the operating period of nuclear power plants to “40 years in principle, with a maximum of 60 years,” and had stated that it “does not envision” rebuilding or adding new plants, but 11 years and 9 months after the accident, the government is making a major change in its nuclear policy.
According to the Ministry of Economy, Trade and Industry, nuclear power plants will be allowed to operate for more than 60 years, excluding the period of suspension due to the Nuclear Regulation Authority’s examination and judicial decisions for restarting operations. The revised bill is expected to be submitted to the ordinary Diet session next year.
In addition, the company will move forward with concrete plans to rebuild nuclear power plants that have been decided to be decommissioned with next-generation nuclear power plants, based on the assumption that safety is ensured and that the local governments in which the plants are located have their understanding. The construction of new nuclear power plants is estimated to cost more than 1 trillion yen, and the government will also consider financial support measures to help electric power companies bear the initial costs.
The basic policy will also include the development of the power grid to maximize the use of renewable energy.
At the end of July, Prime Minister Fumio Kishida instructed relevant ministries and agencies to advance discussions on overcoming the energy crisis caused by Russia’s invasion of Ukraine and the GX as one, and to specify items requiring a political decision.
◆ While uninhabitable areas still remain and compensation for the affected people is still ongoing
Prime Minister Kishida is calling it a “political decision” to change the nuclear energy policy. While the GX’s cause of reforming the socioeconomic system to combat global warming has been raised, the maximum utilization of nuclear power plants is a bad move, a measure to prolong the life of an industry that is not expected to grow.
There are two pillars of the government’s decision to utilize nuclear power plants: The first is to cut to the bare bones the rule of “40 years in principle, with a maximum of 60 years” for operation, effectively allowing operation “beyond 60 years.
Ensuring the safety of old nuclear power plants requires an enormous amount of manpower, money, and time. Nuclear power plants, which the government has promoted as an “inexpensive power source,” would impose a tremendous double-digit trillion-yen burden on electric power companies if even one severe accident were to occur. The accident at TEPCO’s Fukushima Daiichi Nuclear Power Plant 11 years and 9 months ago brought this to light.
The other pillar of the plan is to rebuild the decommissioned nuclear power plants with next-generation nuclear power plants. Although it is touted as the introduction of new technology, the number of human resources in the industry has decreased since the Fukushima accident, and there is an undeniable lack of personnel and technical capabilities. Nuclear power plant construction has long ceased, and nuclear power plant exports, promoted as a growth strategy by the Shinzo Abe administration, the longest in the postwar era, have failed at every turn.
At the site of the world’s worst nuclear accident, located 220 kilometers from Tokyo, the goal of restoration work remains elusive. Uninhabitable areas remain in the vicinity of the plant, and compensation for the victims is still ongoing. There is no hope for political decisions that do not face reality. （Shinichi Ogawa)

Take Japan to court for nuclear water dumping
By Zhang Zhouxiang | China Daily 2023-01-05
The Japanese government had announced in April 2020 that it plans to dump nuclear waste water from its wrecked Fukushima nuclear plant into the ocean from the spring of 2023.
As the date approaches, and given Japan’s record, it will not be surprising if Japan starts dumping the water any time soon without giving other countries advance notice.
While the action will save the Japanese government and the Tokyo Electric Power Company money and trouble, it will also shift the trouble and cost onto other nations, the Pacific ones in particular. There is a precedent here. Years after the United States carried out nuclear tests on the Bikini Atoll, also in the Pacific, from 1946 to 1958, radiation levels there were considered too high to allow resettlement in 1998.
Fishermen from China, the Republic of Korea and other Southeast Asian countries, including from Japan, depend on the waters in the region to make a living. No wonder, Japanese fishermen were protesting the move to dump nuclear waste into the waters.
The US, which Japan always looks up to, has supported Japan’s plan despite studies showing that the region most polluted by the discharge will be the US’ west coast in two years…………
Senior Japanese officials, despite bowing politely at news conferences, have shown no sincerity in negotiating with their Pacific neighbors. When they announced the decision to dump the water into the ocean, they did not ask for understanding from any side except the US.
There is the UN Convention on the Law of the Sea and multiple nuclear safety conventions to which Japan is a signatory, but it has helped little. It is time for all sides involved to sue the Japanese government in international courts. Japan cannot do this evil deed and just walk away unpunished. https://global.chinadaily.com.cn/a/202301/05/WS63b613aba31057c47eba7bd1.html
Japan’s shortage of engineers and manufacturing capacity sets back its nuclear ambitions
Japan’s ambitions to reboot its nuclear industry risk being set back by a
shortage of engineers and manufacturing capacity that has atrophied in the
decade following the Fukushima nuclear disaster.
Prime Minister Fumio Kishida’s new policy calls for the construction of new nuclear power
plants, raising hopes for Japanese manufacturers that are working on
smaller reactors and other upgraded nuclear technologies. But the
industry’s nuclear supply chain is under strain, warned industry executives
and experts. The 2011 accident triggered a massive exit of more than 20
manufacturers, including Kawasaki Heavy Industries and Sumitomo Electric
Industries.

KEPCO: 197 employees obtained national licenses illegally, also engaged in nuclear power plant construction work
December 20, 2022
On December 20, KEPCO announced that 197 employees of KEPCO and its group companies (17 of whom had retired) had taken the technical certification examination for construction management engineers, a national certification that is required for process management in construction work, without the required period of work experience, and had fraudulently obtained the certification. An investigation report by outside lawyers found no evidence of systematic involvement in the fraud.
The Osaka District Court found no problems with the quality of construction work performed by the company’s employees, including 15 cases involving the three nuclear power plants in its jurisdiction, in which the improperly qualified employees were engaged as chief engineers.

Kashiwazaki Kariwa, a Distant Recovery of Confidence TEPCO Shares Crisis Awareness to Prevent Misconduct
Deputy General Manager Daito explains the operating floor. Before entering the building, biometric authentication and other enhancements were in place.
December 19, 2022
A series of scandals, including flaws in anti-terrorism measures, at the Kashiwazaki Kariwa Nuclear Power Plant (Niigata Prefecture), which Tokyo Electric Power Company (TEPCO) aims to restart, has called into question TEPCO’s efforts to restore trust. If distrust grows, it could affect the decommissioning of the Fukushima Daiichi Nuclear Power Plant, which caused the accident. As an operator involved in nuclear power generation, TEPCO is required to improve its internal structure to prevent misconduct, such as by ensuring that each and every employee shares a sense of crisis.
Crisis awareness “is a weak point
In October, the Local Newspaper Energy Study Group, a group of local newspapers in areas where nuclear facilities are located, visited the Kashiwazaki Kariwa Nuclear Power Plant to observe the status of remedial measures being taken. Masaki Daito, 56, deputy director of the Kashiwazaki Kariwa Nuclear Power Plant, admitted to a lack of awareness of the crisis, saying, “There were parts of the situation that we should have been aware of, but we were naive in our understanding of the situation.
In September 2008, an employee of the plant took a colleague’s ID card without permission and entered the central control room illegally, and in April 2009, the Nuclear Regulation Authority issued an order prohibiting the transfer of nuclear fuel. In April 2009, the Regulatory Commission issued a de facto operation ban order prohibiting the transfer of nuclear fuel. The restart of the plant has been put on hold, and TEPCO officials stress that they will work to restore trust in the plant, saying, “Without the understanding of the local community, we will not be able to restart the plant.
Improvement Measures, Starting with Greetings
In response to the series of scandals, TEPCO is working on 36 improvement measures related to the protection of nuclear materials. A Security Management Department has been established within the power plant, the personnel structure has been reviewed, and the budget for equipment has been expanded from 20 billion yen to 58 billion yen. During the inspection tour, the monitoring system was strengthened, with biometric authentication required to enter the “operating floor,” the upper level of the Unit 6 reactor.
TEPCO believes that a lack of communication with employees and workers at partner companies is behind the scandals. The company explained that as a measure to improve the situation, executives and others are standing at the main gate in the morning and making efforts to conduct a “greeting campaign,” but an unusual situation comes to mind in which a review of the basics is unavoidable.
Response is backward and “lousy.
How did the local administration, business community, and residents react to the scandal? The study group interviewed Masahiro Sakurai, 60, mayor of Kashiwazaki City, and Masao Nishikawa, 66, chairman of the Kashiwazaki Chamber of Commerce and Industry. Both are in favor of restarting the nuclear reactors, but they are also very critical of TEPCO in light of the scandals.
In a word, they are lousy. Mayor Sakurai laments TEPCO’s backward steps, such as strengthening biometric authentication after the scandal. While he praises TEPCO’s measures to deal with the scandal, saying that “they are making efforts,” he also points out that a sense of tension and crisis awareness has not penetrated the company’s ranks. Chairman Nishikawa also stated that “the relationship of trust has broken down,” and revealed that he had submitted a letter of request to TEPCO to protest the situation.
Kazuyuki Takemoto, 72, a resident of Kariwa Village who has been campaigning against the plant, questioned the government’s nuclear fuel cycle policy, including the disposal of spent nuclear fuel, saying, “The government is desperately trying to get the plant restarted, but can it really be moved? TEPCO wants to move forward with the restart, but it must not forget the lessons of the nuclear accident. In the visitor’s house at the Kashiwazaki Kariwa Nuclear Power Plant, there is a panel that reads, “Our responsibility for the recovery of Fukushima. How will they face these words and show them through their actions? The public is watching closely. (News Department, Satoshi Mizuno)

Data rewriting and erroneous statements…Sloppy handling continues at Tsuruga Nuclear Power Plant Unit No.2 of JAERI, Regulatory Commission suggests termination of review if no improvement is made

December 19, 2022
At a special meeting on December 19, the Nuclear Regulation Authority (NRA) exchanged opinions with Mamoru Muramatsu, president of Japan Atomic Power Company (JAERI), and others regarding the review of Tsuruga Unit 2 (Fukui Prefecture), where inappropriate rewriting of geological data was discovered. Shinsuke Yamanaka, chairman of the regulatory commission, said that if the data is not improved in the future, “the commission will have to discuss whether to continue the examination,” and indicated that he would consider suspending or terminating the examination.
The rewriting of the data was discovered in February 2020 when the regulatory commission pointed it out. In order to determine whether the fault directly under the reactor building was an active fault that could cause an earthquake, the state of the geological strata taken out by drilling was rewritten in 80 locations. Many other errors were also found.
The regulatory commission’s examination, which had been suspended, resumed on March 9 because the company had established rules for entering data, but at that time, new errors were also found. The number of errors in the data has totaled 1,296 so far.
At the meeting, Akira Ishiwata, a member of the committee in charge of reviewing earthquake and tsunami countermeasures, said, “There are 1,300 errors, and only JAEPCO would submit such materials. If there are any more errors, it will be difficult to continue the examination. Mr. Yamanaka expressed his distrust, asking, “Are they sure about their technical capabilities? (Nozomi Masui)

Fukushima, Our ongoing accident.
Dec 19, 2022
What happens to the damaged reactors? The territories evacuated by 160 000 people? What are the new conditions for their return to the contaminated area since the lifting of the governmental aid procedures? Are lessons still being learned by our national operator for its own nuclear plants? We must not forget that a disaster is still unfolding in Japan and that EDF was supposed to upgrade its fleet on the basis of this feedback, which has still not been finalized.
Almost twelve years after the Fukushima disaster, Japan is still in the process of dismantling and ‘decontaminating’ the nuclear power plant, probably for the next thirty to forty years as well. In the very short term, the challenges are posed by the management of contaminated water.
- All the contaminated water will be evacuated into the sea, by dilution over decades
- Each intervention in the accident reactors brings out new elements
- This has an impact on the schedule and the efficiency of the means used
- At the same time, the Japanese government’s objective is to rehabilitate the contaminated areas at any cost
- None of the French reactors is up to date with its safety level according to the post-Fukushima measures promulgated
- Japan will resume its nuclear policy, time having done its work on memories
The great water cycle
Although Japanese politicians claim that they have finally mastered the monster, the colossal task of cleaning up the site is still far from being completed to allow for the ultimate dismantling, with the length of time competing with the endless financing.
After so many years of effort, from decontamination to the management of radioactive materials and maneuvers within the dismantled plant, the actions on site require more and more exceptional means, exclusive procedures, and unprecedented engineering feats (such as robotic probes), while the nuclear fuel inside continues to be cooled permanently by water (not without generating, to repeat, millions of liters of radioactive water).
But the hardest part is yet to come: containing the corium, an estimated 880 tons of molten radioactive waste created during this meltdown of the reactor cores, and managing the thousands of fuel rods. So much so that the complete cleanup and dismantling of the plant could take a generation or more for a total estimated cost of more than 200 billion dollars (according to an assessment published by the German insurer Munich Re, Japan is 150 billion euros), a low range since other estimates raise the bill between 470 and 660 billion dollars, which is not in contradiction with the costs of an accident projected by the IRSN in France.
The removal of this corium will remain the most essential unresolved issue for a long time. Without it, the contamination of this area will continue. In February 2022, the operator Tepco (Tokyo Electric Power Company Holdings Inc.) tried again to approach the molten fuel in the containment of a reactor after a few more or less unsuccessful attempts, the radioactivity of 2 sieverts/hour being the end of everything, including electronic robots. This withdrawal seems quite hypothetical, even the Chernobyl reactor has never been removed and remains contained in a sarcophagus.
(source: Fukushima blog and Japan’s Nuclear Safety Authority NRA)
Until that distant prospect arrives, the 1.37 million tons of water will have filled the maximum storage capacity. This water was used to cool the molten fuel in the reactor and then mixed with rainwater and groundwater. The treatment via an Advanced Liquid Processing System (ALPS) is touted as efficient, but does not remove tritium. Relative performance: Tepco has been repeatedly criticized for concealing and belatedly disclosing problems with filters designed to prevent particles from escaping into the air from the contaminated water treatment system: 24 of the 25 filters attached to the water treatment equipment were found to be damaged in 2021, an already known defect that resulted in no investigation of the cause of the problem and no preventive measures after the filters were replaced.
The management of this type of liquid waste is a problem shared by the Americans. On site, experts say that the tanks would present flooding and radiation hazards and would hamper the plant’s decontamination efforts. So much so that nuclear scientists, including members of the International Atomic Energy Agency (IAEA) and the Japanese Nuclear Regulatory Authority, have recommended controlled release of the water into the sea as the only scientifically and financially realistic option.
In the end, contaminated water would have to be released into the sea through an underwater tunnel about a kilometer offshore, after diluting it to bring the concentration of tritium well below the percentage allowed by regulation (the concentration would be below the maximum limit of tritium recommended by the World Health Organization for drinking water). Scientists say that the effects of long-term, low-dose exposure to tritium on the environment and humans are still unknown, but that tritium would affect humans more when consumed in fish. The health impact will therefore be monitored, which the government already assures us it is anticipating by analyzing 90,000 samples of treated water each year.
Assessment studies on the potential impact that the release of stored contaminated water into the ocean could have therefore seem insufficient. For tritium, in the form of tritiated water or bound to organic matter, in addition to its diverse behavior according to these configurations, is only part of the problem. Some data show great variability in the concentrations of contaminants between the thousand reservoirs, as well as differences in their relative quantities: some reservoirs that are poor in tritium are rich in strontium 90 and vice versa, suggesting a high variability in the concentrations of other radionuclides and a dilution rate that is not so constant. All the ignorance currently resides on the still unknown interactions of the long-lived radioactive isotopes contained in the contaminated water with the marine biology. It is in order to remove all questions that a complete and independent evaluation of the sixty or so radioisotopes is required by many organizations.
As it stands, with the support of the IAEA so that dilution meets expectations, depending on currents, flows …, the release of contaminated materials would take at least forty years. Opponents of such releases persist in proposing an alternative solution of storage in earthquake-resistant tanks in and around the Fukushima facility. For them, “given the 12.3-year half-life of tritium for radioactive decay, in 40 to 60 years, more than 90% of the tritium will have disappeared and the risks will be considerably reduced,” reducing the direct nuisance that could affect the marine environment and even the food chain.
Modelling of marine movements could lead the waste to Korea, then to China, and finally to the Federated States of Micronesia and Palau. As such, each of the impacted countries could bring an action against Japan before the International Tribunal for the Law of the Sea to demand an injunction or provisional measures under international law.
Faced with these unresolved health issues, China, South Korea, Taiwan, local fishing communities continue to oppose this management plan, but the work is far from being completed and the problem of storage remains. Just like the ice wall built into the floor of the power plant, the release of contaminated water requires huge new works: the underwater pipe starts at about 16 meters underground and is drilled at a rate of five to six meters per day.
Time is of the essence. The tanks should reach their maximum capacity by the fall of 2023 (the volume of radioactive water is growing at a rate of about 130 to 140 tons per day). But above all, it is necessary to act quickly because the area is likely to suffer another earthquake, a fear noted by all stakeholders. With the major concern of managing the uranium fuel rods stored in the reactors, the risks that radioactivity will be less contained increase with the years.In France, releases to the sea are not as much of a problem: the La Hague waste reprocessing site in France releases more than 11,000 terabecquerels per year, whereas here we are talking about 22 terabecquerels that would be released each year, which is much less than most of the power plants in the world. But we will come back to this atypical French case…
Giant Mikado
The operator Tepco has successfully removed more than 1500 fuel bundles from the reactor No. 4 of the plant since late 2014, but the hundreds still in place in the other three units must undergo the same type of sensitive operation. To do this, again and again, undertake in detail the clearing of rubble, the installation of shields, the dismantling of the roofs of buildings and the installation of platforms and special equipment to remove the rods… And ultimately decide where all the fuel and other solid radioactive debris will have to be stored or disposed of in the long term. A challenge.
The fuel is the biggest obstacle to dismantling. The solution could lie, according to some engineers, in the construction of a huge water-filled concrete tank around one of the damaged reactors and to carry out the dismantling work in an underwater manner. Objectives and benefits? To prevent radiation from proliferating in the environment and exposing workers (water is a radiation insulator, we use this technique in our cooling pools in France) and to maximize the space to operate the heavy dismantling equipment being made. An immersion solution made illusory for the moment: the steel structure enveloping the building before being filled with water is not feasible as long as radiation levels are so high in the reactor building, preventing access by human teams. In short, all this requires a multitude of refinements, the complexity of the reactors adding to the situations made difficult by the disaster.
Experience, which is exceptional in this field, is in any case lacking. What would guarantee the resistance of the concrete of the tanks over such long periods of time, under such hydraulic pressures? The stability of the soils supporting such structures? How can the concrete be made the least vulnerable possible to future earthquakes? How to replace them in the future?
All these difficulties begin to explain largely the delays of 30 to 40 to dismantle. The reactors are indeed severely damaged. And lethal radiation levels equivalent to melted nuclear fuel have been detected near one of the reactor covers, beyond simulations and well above previously assumed levels. Each of the reactors consists of three 150-ton covers, 12 meters in diameter and 60 centimeters thick: the radiation of 1.2 sieverts per hour is prohibitive, especially in this highly technical context. There is also no doubt that other hotspots will be revealed as investigations are carried out at the respective sites. The Nuclear Damage Compensation and Decommissioning Facilitation Corporation (NDF), created in 2014, has the very objective of trying to formulate strategic and technical plans in order to proceed with the dismantling of said reactors. Given the physical and radiological conditions, the technical and logistical high-wire act.
Also, each plan is revised as information is discovered, as investigations are conducted when they are operable. For example, the reinforcing bars of the pedestal, which are normally covered with concrete, are exposed inside Reactor No. 1. The concrete support foundation of a reactor whose core has melted has deteriorated so badly that rebar is now exposed.
The cylindrical base, whose wall is 1.2 meters thick, is 6 meters in diameter. It supports the 440-ton reactor pressure vessel. The reinforcing rods normally covered with concrete are now bare and the upper parts are covered with sediment that could be nuclear fuel debris. The concrete probably melted under the high temperature of the debris. The strength of the pedestal is a major concern, as any defect could prove critical in terms of earthquake resistance.
Nothing is simple. The management of human material appears less complex.
Bringing back to life, whatever it takes
In the mountains of eastern Fukushima Prefecture, one of the main traditional shiitake mushroom industries is now almost always shut down. The reason? Radioactive caesium exceeding the government’s maximum of 50 becquerels per kilogram, largely absorbed by the trees during their growth. More than ten years after the nuclear disaster, tests have revealed caesium levels between 100 and 540 becquerels per kilogram. While cesium C134 has a radioactive half-life of about two years and has almost disappeared by now, the half-life of cesium C137 is about 30 years and thus retains 30% of its radioactivity 50 years after the disaster, and 10% after a century.
As more than two thirds of Fukushima prefecture is covered by forests, nothing seems favorable in the short term to get rid of all or part of the deposited radioactivity, as forests are not part of the areas eligible for ‘decontamination’, unlike residential areas and their immediate surroundings.
On the side of the contaminated residential and agricultural areas, ‘decontamination’ measures have been undertaken. But soil erosion and the transfer of contaminants into waterways, frequent due to typhoons and other intense rain events, are causing the radioactive elements to return, moving them incessantly. Scientists are trying to track radioactive substances to better anticipate geographical fluctuations in doses, but nothing is simple: the phenomena of redistribution of the initial contamination deposits from the mountains to the inhabited low-lying areas are eternal.
The Ministry of the Environment is considering the reuse of decontaminated soils (official threshold of 8,000 becquerels per kilogram), with tests to be conducted. For now, a law requires the final disposal of contaminated soil outside Fukushima Prefecture by 2045, which represents about 14 million cubic meters (excluding areas where radiation levels remain high). This reuse would reduce the total volume before legal disposal.
More generally, Japan has for some years now opted for the strategy of holding radiological contamination as zero and/or harmless. This is illustrated by the representative example of the financial compensation given to farmers, designed so that the difference between pre- and post-accident sales is paid to them as compensation for “image damage”, verbatim.
Finally, in the midst of these piles of scrap metal and debris, it is necessary to make what can be made invisible. Concerning radioactive waste for example, it must be stored in time. On the west coast of the island of Hokkaidō, the villages of Suttsu and Kamoenai have been selected for a burial project. Stainless steel containers would be stored in a vitrified state. But consultation with the residents has not yet been carried out. This is not insignificant, because no less than 19,000 tons of waste are accumulating in the accidental, saturated power plants, and must find a place to rest for hundreds of years to come.
In this sparsely populated and isolated rural area, as in other designated sites, to help with acceptance, 15 million euros are being paid to each of the two municipalities to start the studies from 2020. 53 million are planned for the second phase, and much more in the final stages. This burial solution seems inevitable for Japan, as the waste cannot remain at the level of the surface power plants and is subject at all times to the earthquakes that are bound to occur over such long periods (strong earthquakes have struck off the prefecture in 2021 and 2022). The degrees of dangerousness thus allow the government to impose a default choice, for lack of anything better.
On December 6, 2022, the Director General of the IRSN met with the President of Fukushima University and with a manager of the Institute of Environmental Radioactivity (IER). What was the objective? To show the willingness of both parties to continue ongoing projects on the effects of radioactive contamination on biodiversity and environmental resilience.
But France will not have waited for the health results of a disaster to learn and commit itself to take into account any improvement likely to improve the nuclear safety of its reactors. No ?
Experience feedback
After a few reactor restarts that marked a major change in its nuclear energy policy (ten nuclear reactors from six plants out of a total of fifty-four were restarted by June 2022), the Japanese government is nonetheless planning to build new generation nuclear power plants to support its carbon emission reduction targets. (A memorandum of understanding was signed by the Japan Atomic Energy Agency, Mitsubishi Heavy Industries and Mitsubishi FBR Systems with the American start-up TerraPower to share data for the Natrium fast neutron reactor project; the American company NuScale Power presented its modular reactor technology). But above all, the government is considering extending the maximum service life of existing nuclear reactors beyond 60 years. Following the disaster, Japan had introduced stricter safety standards limiting the operation of nuclear reactors to 40 years, but there is now talk of modernizing the reactors with safety features presented as “the strictest in the world”, necessarily, to meet safety expectations. Their program is worthy of a major refurbishment (GK).
But in France, where are we with our supplementary safety assessments?
The steps taken after the Fukushima disaster to reassess the safety of French nuclear facilities were designed to integrate this feedback in ten years. More than ten years after the start of this process of carrying out complementary safety assessments (CSA), this integration remains limited and the program has been largely delayed in its implementation.
Apparently, ten years to learn all the lessons of this unthinkable accident was not enough. Fear of the probable occurrence of the impossible was not the best motivation to protect the French nuclear fleet from this type of catastrophic scenario, based solely on these new standards. Concerning in detail the reality of the 23 measures identified to be implemented (reinforcement of resistance to earthquake and flooding, automatic shutdown in the event of an earthquake, ultimate water top-up for the reactor and cooling pool, detection of corium in the reactor vessel, etc.), the observation is even distressing: not a single reactor in operation is completely up to standard.
According to NegaWatt’s calculations, at the current rate of progress and assuming that funding and skills are never lacking, it would take until 2040 for the post-Fukushima standards to be finally respected in all French reactors. And even then, some of the measures reported as being in place are not the most efficient and functional (we will come back to the Diesels d’ultime secours, the DUS of such a sensitive model).
Even for the ASN, the reception of the public in the context of post-accident management could appear more important than the effectiveness of the implementation of the measures urgently imposed.
Then, let us complete by confirming that France and Japan have a great and long common history which does not stop in nuclear matters. Among this history, let us recall that Japan lacks facilities to treat the waste from its own nuclear reactors and sends most of it abroad, especially to France. The previous transport of highly radioactive Mox (a mixture of highly toxic plutonium oxide and reprocessed uranium oxide) to Japan dates back to September 2021, not without risk even for the British company specialized in this field, a subsidiary of Orano. The final request for approval for the completion of the Rokkasho reprocessing plant, an important partnership and technology transfer project, is expected in December 2022, although the last shipments to Japan suffered from defective products from Orano’s Melox plant, a frequent occurrence because of a lack of good technical homogenization of the products.
No one is immortal
In the meantime, the ex-managers of the nuclear power plant have been sentenced to pay 95 billion euros for having caused the disaster of the entire eastern region of Japan. They were found guilty, above all, of not having sufficiently taken into account the risk of a tsunami at the Fukushima-Daiichi site, despite studies showing that waves of up to 15 meters could hit the reactor cores. Precisely the scenario that took place.
Worse, Tepco will be able to regret for a long time to have made plan the cliff which, naturally high of 35 meters, formed a natural dam against the ocean and the relatively frequent tsunamis in this seismic zone. This action was validated by the Japanese nuclear safety authorities, no less culpable, on the basis of the work of seismologists and according to economic considerations that once again prevailed (among other things, it was a question of minimizing the costs of cooling the reactors, which would have been operated with seawater pumps).
The world’s fourth largest public utility, familiar with scandals in the sector for half a century, Tepco must take charge of all the work of nuclear dismantling and treatment of contaminated water. With confidence. The final total estimates are constantly being revised upwards, from 11,000 billion to 21,500 billion yen, future budgets that are borrowed from financial institutions, among others, with the commitments to be repaid via the future revenues of the electricity companies. A whole financial package that will rely on which final payer?
Because Tepco’s financial situation and technical difficulties are deteriorating to such an extent that such forty-year timetable projections remain very hypothetical, and the intervention of the State as a last resort is becoming more and more obvious. For example, the Japanese government has stated that the repayment of more than $68 billion in government funding (interest-free loans, currently financed by government bonds) for cleanup and compensation for the Fukushima Daiichi nuclear power plant disaster, owed by Tepco, has been delayed. Tepco’s mandatory repayments have been reduced to $270 million per year from the previous $470 million per year. It is as much to say that the envisaged repayment periods are as spread out as the Japanese debt is abysmal.
Despite this chaotic long-term management, the Japanese government has stated that it is considering the construction of the next generation of nuclear power plants, given the international energy supply environment and Japan’s dependence on imported natural resources. Once the shock is over, business and realpolitik resume.
On a human scale, only radioactivity is immortal.
