Japan should consider shifting to direct disposal of nuclear waste

February 20, 2023
The Kishida administration has unveiled a policy initiative to deal with high-level radioactive waste from nuclear power plants through “united government-wide” efforts.
The government plans to step up its efforts to find a local government willing to host a final disposal site for nuclear waste. The government should naturally assume the responsibility of dealing with this problem, but it should not pressure local governments to host a disposal facility.
According to the draft revision to the basic policy for tackling the problem, which was announced earlier in February, the government will set up a “council for discussions” with interested local governments to discuss the challenges and possible policy responses.
Based on these talks, the national government will propose in stages to local administrations to accept a survey for a disposal site.
Under the current basic policy, the Ministry of Economy, Trade and Industry published in 2017 a map of the nation showing potential areas for locating a deep geological disposal site. At this site, spent fuel would be buried in engineered facilities 300 or more meters below ground level.
The initial phase of assessing two municipalities in Hokkaido for their suitability to host such a disposal facility began three years ago. The first stage of the process, called “bunken chosa” (literature survey), involves reviews of geological maps and research papers concerning local volcanic and seismic hazards and other related factors.
No other municipalities have yet to volunteer for undertaking this process.
High-level radioactive waste from spent nuclear fuel, however, is not the only kind of nuclear waste that must be disposed of. Other types of nuclear waste include materials from decommissioned reactors and melted “fuel debris” from the stricken Fukushima No. 1 nuclear power plant, which has been left untreated.
One inconvenient fact for supporters of nuclear power generation is that no solution has been found as to where all these kinds of nuclear waste should be disposed of.
At nuclear power plants across the nation, growing amounts of spent nuclear fuel are fast filling up the spent fuel pools within the premises, with not much room left. Operating nuclear plants will eventually start generating spent fuel that cannot be stored anywhere.
The government’s move to accelerate its program to build a final disposal site is aimed at defusing criticism about its policy shift toward expanding nuclear power generation by signaling a willingness to tackle these policy challenges.
Since there is already a large amount of spent nuclear fuel, a disposal site is clearly necessary. A broad consensus on the issue should be built through debate involving the entire nation, including citizens of major cities who consume huge amounts of electricity.
It would be better for such a debate to be held at an independent organization that is separated from the industry ministry, which promotes the use of atomic energy. The law for regulating measures related to the final disposal of radioactive waste should be reviewed for necessary revisions.
Since Article 1 of the law refers to the “proper use of nuclear power,” the construction of a final disposal facility could justify the long-term use of nuclear power.
That would mean nuclear plants will keep producing spent fuel for decades to come. This prospect will make local communities that may host the disposal facility concerned about the possibility that radioactive waste may be brought to the site without end.
The law is based on the assumption that a nuclear fuel reprocessing system to recover plutonium and uranium from spent nuclear fuel to be reused in reactors will be established.
Northern Europe and many other countries with an advanced program to deal with radioactive waste have adopted the approach known as direct disposal, a management strategy where used nuclear fuel is disposed of in a deep underground repository, without any recycling.
Instead of adhering to the now unworkable program to establish a fuel recycling system, the government should designate direct disposal as a realistic option.
This is the time to fundamentally rethink the law, which was enacted more than two decades ago without much serious debate, taking into consideration the experiences of the Fukushima nuclear disaster.
Final disposal of nuclear waste is “the responsibility of the government”…but is it safe? What is happening in towns and villages in Hokkaido, where a literature review is underway
February 15, 2023
The Fumio Kishida administration is moving forward with the utilization of nuclear power. This time, he has put together a policy to take national responsibility for the final disposal of high-level radioactive waste from spent nuclear fuel. Despite the encouraging tone of the words, distrust is mounting. The government has emphasized “national responsibility” in its response to the accident at TEPCO’s Fukushima Daiichi Nuclear Power Station, but there have been instances in which the government has tended to act arbitrarily. What developments are expected in the future regarding the final disposal of the waste? How will this affect the towns of Sutsu and Kamieuchi in Hokkaido, where literature surveys are underway? (The following is a summary of the report by Yuzuru Miyahata and Naoaki Nishida.)
◆Spent nuclear fuel continues to accumulate
The government will make a concerted and concerted effort toward the final disposal of the spent fuel. A ministerial meeting was held on October 10 to discuss the selection of a final disposal site for high-level radioactive waste. The draft revision of the basic policy presented at the meeting clearly stated the above passage. The policy is currently undergoing public comment, and if it is revised, it will be the first time in eight years, since 2015, that the policy has been revised.
High-level radioactive waste from spent nuclear fuel is also known as “nuclear waste. At present, spent nuclear fuel continues to accumulate in storage pools at nuclear power plants, and vitrified waste, which is made by solidifying liquid waste with glass, is being processed.
Spent nuclear fuel from the new conversion reactor Fugen is stored in a pool at the Tokai Reprocessing Plant in Tokai-mura, Ibaraki Prefecture.
Nuclear waste is a troublesome problem because of its extremely high radioactivity and long life. According to the Final Disposal Law enacted in 2000, the plan is to dispose of nuclear waste in a geological formation deep underground, but due to safety concerns and other factors, a concrete roadmap has yet to be drawn.
The government’s emphasis on its responsibility is a reflection of this situation. Since the enactment of the Final Disposal Law, a nationwide public call for proposals, known as the “hand-picked” method, began, and Toyo Town in Kochi Prefecture applied in 2007, but the application was withdrawn due to the fierce opposition of the townspeople. Currently, only the Hokkaido towns of Sutsu-cho and Kamieuchi-mura have accepted the “literature review,” the first step in the selection process.
According to the Agency for Natural Resources and Energy of the Ministry of Economy, Trade, and Industry (METI), approximately 160 explanatory meetings were held throughout Japan over the past five years, but interest in the project was limited. On the other hand, in the case of the other countries where final disposal sites have been decided, the number of candidate sites was narrowed down from about 10 to only one. The person in charge said, “As a result of the survey, there is opposition from the public and the fact that it cannot be used as a disposal site. We need more candidate sites,” he said.
◆Disbelief in government policy: “Can we really do this?
Under the current system, the Nuclear Waste Management Organization (NUMO), to which the power companies contribute the project cost, is responsible for selecting the disposal site and the disposal itself. However, because of the difficulties in selecting a disposal site, when the basic policy was revised in 2003, the government stepped up to the plate by presenting areas that were considered highly suitable. This time, however, the government “decided to step it up a notch,” according to the person in charge of the matter mentioned above.
While Professor Yo Fujimura of Kanagawa Institute of Technology understands that “the national government is responsible for the nuclear power policy because it is a national policy,” he also has some concerns. The national government must not force the local communities to do something.
At the root of his concern is a distrust of the national government. He wonders, “Have the national government and electric power companies done anything to earn our trust in their response to the accident at the Fukushima Daiichi Nuclear Power Plant? For example, the cleanup of contaminated water at the Daiichi Nuclear Power Plant. When he was prime minister, Yoshihide Suga said that the government would take responsibility for the situation, but he turned a deaf ear to the opposition to releasing the water into the ocean and decided to release it after it had been treated.
Even though the government is moving forward with the final disposal of the waste, some doubt whether it can really be done.
It is said that it will take 100,000 years for high-level radioactive waste to become safe. Hideyuki Hirakawa, a professor of science, technology, and society at Osaka University, said, “Japan is an earthquake-prone country. There are active faults everywhere. If a problem is found after moving the waste deep underground, will it be possible to remove the radioactive waste? I have not lost faith in the technology related to nuclear power plants. And how can we be sure of safety 100,000 years from now?
◆The reason why the survey is not progressing is because of the upcoming election.
Now that the Kishida administration has declared that “the national government will take responsibility for the final disposal of the waste,” what do the people of Sutou Town and Kamieuchi Village, where the literature review is underway, think?
The literature review for both towns and villages, which began in November 2020, is still ongoing. Initially scheduled to take about two years, a NUMO spokesperson said, “It is taking longer than expected. We are in the process of asking a working group at METI for their thoughts on how to evaluate the survey results. We have not yet decided how long it will take,” he said.
Once the literature review using geological maps and academic papers is completed, NUMO plans to move on to an overview survey to examine the geology and ground conditions, based on the wishes of the local community. This is the second phase of the survey.
Masayuki Domon, 69, a member of the Kamieuchi Village Council who announced his opposition to the literature survey three years ago, wonders if the reason the survey has not been completed after two years is because an election is coming up. The “election” referred to here is the village council election scheduled for April. Given the current situation in which many village council members are in favor of the project, he suspects that they do not want to make waves.
Mr. Domon said, “Time has passed without sufficient explanation to the villagers. The governor has clearly stated that he will not accept the summary survey, so we have no choice but to urge the village mayor to keep in step with us,” he told himself.
◆Divided opinions and broken relationships
On the other hand, Kazuyuki Tsuchiya, 74, a member of an opposition group in the town of Sutomachi, said of the Kishida administration, “To put it simply, it’s just infuriating. When they emphasize that ‘the final disposal is the responsibility of the national government,’ it sounds like ‘the national government is pushing hard for the selection of a disposal site in towns and villages where investigations are underway. What the government says cannot be trusted at all.
The town’s ordinance stipulates that a referendum will be held when the town moves from a literature review to an overview survey, but the mayor’s decision is not binding.
The town council’s opinion carries weight, and currently it is split evenly between those in favor and those opposed. However, “I am having a hard time finding a candidate,” he said. In this small town, the people are closely knit, and some of them have lost their relationships with each other because of the split in support of and against the project.
He is also wary of how the proponents of the project will react to the briefing by NUMO representatives, saying, “Even if they call it a ‘place for dialogue,’ the actual situation is different. It has become a place for one side to express its viewpoints. He fears that the NUMO representatives will be more inclusive of the proponents and more likely to cut off opponents.
On October 10, the Kishida administration passed a cabinet decision on the “Basic Policy for the Realization of Green Transformation (GX),” which includes the active use of nuclear power plants. The timing of the decision to present the draft basic policy on final disposal at the time of the outbreak of objections underscored the “responsibility of the national government.
◆ “It is only making the local communities suffer and be troubled.
Tatsujiro Suzuki, a professor of nuclear policy at Nagasaki University, said, “If there is no final disposal site, they will blame us even more. We are only aware of such voices. It has a strong sense of appeal.” He doubts the intention of the government to deflect criticism. He then added, “Even if we say we will focus on the selection of a disposal site, the Federation of Electric Power Companies of Japan (DENJI-REN) will be in charge of the process. There will be no particular change.
While discussion of a final disposal site is inevitable, it would be problematic to proceed without the consent of the local residents, as was the case in the town of Sutsu and the village of Kamieuchi.
Tsunehide Chino, associate professor of environmental sociology at Shinshu University, said, “The government has often used the phrase ‘government-led promotion of understanding’ with regard to the final disposal site, but even looking at the two Hokkaido towns and villages today, there is no consensus of opinion, and in fact, this is causing division. This has only caused distress and pain to the local communities,” he continued. The problem is that the administration has not faced up to the harsh reality of the situation and has taken the easy way out by not trying to gain the public’s understanding. The government should abandon its technological and economic optimism that nuclear power is safe and that the cost of electricity will go down.
◆Desk Memo
When nuclear power plants are operated, waste is generated. But, since a disposal site has not been decided, the amount of waste is accumulating. It is difficult to manage it. It is also hard to find a place to put it. What should be done is obvious. Stop the nuclear power plants, prevent the increase in waste, and in the meantime, discuss where to dispose of the waste. However, the government has a policy of operating nuclear power plants. The more waste we generate, the more trouble we have to clean up. They are irrationally thinking and acting arbitrarily. The situation is too bad. (Sakaki)
Japan watchdog OKs new safety rules to extend reactor life
The Fukushima Daiichi nuclear power plant sits in coastal towns of both Okuma and Futaba, as seen from the Ukedo fishing port in Namie town, northeastern Japan, on March 2, 2022
February 14, 2023
TOKYO (AP) — Japanese nuclear regulators on Monday approved contentious safety evaluation changes and draft legislation to allow aging reactors to operate longer, in a rare split decision in which one of the five commissioners dissented.
The Nuclear Regulation Authority, responding to a new government policy to scrap the current 60-year operating limit for reactors, adopted a new system in which additional operating extensions can granted every 10 years after 30 years of service. No maximum limit is specified. The authority also adopted a draft revision of the reactor regulation law for approval by parliament.
It’s a major change from the current 40-year operating limit with a possible one-time extension of up to 20 years, a rule that was introduced as part of stricter safety standards adopted after the 2011 Fukushima nuclear plant disaster.
Prime Minister Fumio Kishida’s Cabinet adopted a plan last Friday to maximize the use of nuclear energy, including accelerating restarts of halted reactors, prolonging the operational life of aging plants and development of next-generation reactors to replace those designated for decommissioning, as Japan struggles to secure a stable energy supply and meet its pledge to reach carbon neutrality by 2050.
One of the authority’s five commissioners, Akira Ishiwatari, a Tohoku University geologist, opposed the changes.
“We are open to revisions (to rules) if changes are clearly to contribute to greater safety for scientific or technical reasons. To me, these changes do not serve either purpose,” Ishiwatari said at Monday’s commission meeting.
Another commissioner, Tomoyuki Sugiyama, deputy chief of the Japan Atomic Energy Agency’s nuclear safety research center, said he felt the discussion was “rushed” as a result of government pressure and that the regulatory body should have acted more independently.
Authority Chairman Shinsuke Yamanaka denied that the watchdog yielded to government pressure and said he believes the new safety system is adequate.
The authority’s task is “to inspect the safety of (aging) reactors no matter how long their operational lifespan is,” he said. “We simply do not issue safety permits for reactors with progressing deterioration.”
Anti-nuclear sentiment and safety concerns rose sharply in Japan after the Fukushima disaster, in which a massive earthquake and tsunami damaged the plant’s cooling system, resulting in the meltdown of three reactors and the release of large amounts of radiation.
The government has been pushing for a return to nuclear power amid worries of energy shortages following Russia’s invasion of Ukraine and a global push to reduce greenhouse gases.
While maintaining a 20%-22% target for nuclear energy’s share of the energy mix for 2030, the government previously denied it was considering building new nuclear plants or replacing aged reactors in an apparent attempt to avoid triggering criticism from a wary public.

Japan PM Kishida tells ministers to assuage public concerns over nuclear policy

Mainichi, 17 Feb 23, TOKYO (Kyodo) — Japanese Prime Minister Fumio Kishida urged his ministers Friday to assuage public concerns over the government’s planned policy shift that will allow the operation of nuclear power plants beyond the current limit of 60 years.
The instruction came after the country’s nuclear watchdog decided this week to review regulatory standards on the lifespan of nuclear reactors despite one of the five commissioners remaining opposed to the policy in a rare move.
The government plans to submit related bills to parliament during the current session. The revision will enable the operation of reactors for an extended period by excluding the time spent on inspections and other offline periods from their designed service life.
“I was instructed that the Cabinet should decide on the bills after we are ready to provide thorough explanations at the Diet to clear the public’s anxiety,” industry minister Yasutoshi Nishimura told a press conference………………
On Monday, the Nuclear Regulation Authority formally approved the revision by a majority vote after Akira Ishiwatari, a commissioner in charge of earthquake and tsunami countermeasures, opposed it.
The revision “is not based on new scientific or technical findings. It cannot be said to be a shift to the safe side,” Ishiwatari said. Another member also expressed a cautious stance in making decisions too swiftly. https://mainichi.jp/english/articles/20230217/p2g/00m/0na/060000c
Fukushima: Japan insists release of 1.3m tonnes of ‘treated’ water is safe
Neighbouring countries and local fishers express concern as 12th anniversary of nuclear disaster looms
Justin McCurry, Guardian 15 Feb 23,
“……………….. As the country prepares to mark the 11 March anniversary, one of the disaster’s most troubling legacies is about to come into full view with the release of more than 1m tonnes of “treated” water from the destroyed Fukushima Daiichi nuclear power plant.
The tsunami knocked out the plant’s backup electricity supply, leading to meltdowns in three of its reactors, in the world’s worst nuclear accident since Chornobyl 25 years earlier.
Much has changed since the Guardian’s first visit to the plant in 2012, when the cleanup had barely begun and visitors were required to wear protective clothing and full-face masks. Atmospheric radiation levels have dropped, damaged reactor buildings have been reinforced and robots have identified melted fuel in the basements.
But as the Guardian learned on a recent visit, progress on decommissioning – a process that could take four decades – is being held up by the accumulation of huge quantities of water that is used to cool the damaged reactor cores.
Now, 1.3m tonnes of water – enough to fill about 500 Olympic-sized swimming pools – is being stored in 1,000 tanks that cover huge swathes of the complex. And space is running out.
Two steel pillars protruding from the sea a kilometre from the shore mark the spot where, later this year, the plant’s operator, Tokyo Electric Power [Tepco], plans to begin releasing the water into the Pacific Ocean, in the most controversial step in the Fukushima Daiichi cleanup to date.
The decision comes more than two years after Japan’s government approved the release of the water, which is treated using on-site technology to remove most radioactive materials. But the water still contains tritium, a naturally occurring radioactive form of hydrogen that is technically difficult to separate from water.
The discharge, which is due to begin in the spring or summer, will take place in defiance of local fishing communities, who say it will destroy more than a decade of work to rebuild their industry. Neighbouring countries have also voiced opposition.
The government and Tepco claim the environmental and health impacts will be negligible because the treated water will be released gradually after it has been diluted by large amounts of seawater. The International Atomic Energy Agency says nuclear plants around the world use a similar process to dispose of wastewater containing low-level concentrations of tritium and other radionuclides.
Tepco and government officials who guided a small group of journalists around Fukushima Daiichi this month insisted the science supports their plans to pump the “treated” water – they object to media reports describing it as contaminated – into the ocean………………………………………….
Environmental groups have challenged the Japanese government’s claims that the water will not affect marine life or human health, while the US National Association of Marine Laboratories has pointed to a lack of adequate and accurate scientific data to support its reassurances on safety………………….. https://www.theguardian.com/environment/2023/feb/15/fukushima-japan-insists-release-of-treated-water-is-safe-nuclear-disaster
Many people in the public opinion polls are opposed to the idea, and briefings are being held in various regions… but the Cabinet decides to promote nuclear power plants, ignoring the voices of “grave danger to future generations”
February 11, 2023
The government’s basic policy, which includes measures to promote nuclear power plants, such as rebuilding them and operating them for more than 60 years, received nearly 4,000 opinions (public comments), many of which were against nuclear power. However, the Cabinet decision was made on April 10 without changing the main outline of the policy. The major change in nuclear policy less than six months after Prime Minister Fumio Kishida’s order to study the issue has consistently failed to address the voices of the public. (The Cabinet decision was made on October 10, 2011, without any change in the major nuclear policy.)
◆Consideration of voices within the ruling party
The TEPCO’s Fukushima Daiichi nuclear power plant accident proves that humans have no control over nuclear power plants,” and “It invites grave danger to future generations.
The results of the public solicitation of opinions announced by the government after the cabinet decision were lined with requests for the government to reconsider its decision. A total of 3,966 opinions were received in the public solicitation, which was conducted for about a month from the end of December last year, after the basic policy was decided at the government meeting. The government has clarified the contents of 356 opinions and their responses by summarizing similar opinions.
The government’s response to the negative opinions on nuclear power emphasized that the stable supply of electricity is in crisis due to changes in the energy situation caused by the crisis in Ukraine. The government reiterated its explanation that it will utilize nuclear power along with renewable energy and other energy sources that have decarbonizing effects.
Since the end of the public comment period, there has been only one major revision to the basic policy, related to nuclear power. Regarding the reconstruction of nuclear power plants, which had not been envisioned by the government after the Fukushima accident, the target location was elaborated from “nuclear power plants that have been decided to be decommissioned” to “within the premises of nuclear power plants that have been decided to be decommissioned. This is a strong indication that the government took into consideration the opinions of the nuclear power prudent within the ruling party.
◆Not listening to the voice of the people, “They are making fun of the victims.
The basic policy was discussed by a number of METI experts. Although a number of committee members who are negative about nuclear power plants called for a national debate, the public’s voice was not heard before the policy was decided.
After deciding on the basic policy at the end of last year, METI began holding explanatory meetings in mid-January in 10 cities across Japan where METI and other bureaus are located. So far, they have been held in Nagoya, Saitama, Osaka, and Sendai, and will continue until early March.
Ruiko Muto, co-chairperson of the Liaison Association of Organizations Affected by the Nuclear Power Plant Accident in Miharu-machi, Fukushima Prefecture, commented at a press conference on March 10, “I don’t understand what the meetings are for. It is ridiculous that the meeting was not held in Fukushima Prefecture, a disaster-stricken area, and that they are making fun of the victims of the disaster.
◆It’s conclusory, forced, and unacceptable as a method of policy making.” It is unacceptable as a method of policy making.
Opposition to the policy is also smoldering among regulators. The basic policy stipulates that the Nuclear Regulation Authority (NRA) will conduct rigorous examinations and regulations as a precondition for utilizing nuclear power plants. At a regular meeting of the regulatory commission on August 8, Akira Ishiwatari, a member of the commission, opposed the transfer of the 40-year operating period, with a maximum of 60 years, stipulated in the Nuclear Reactor Regulation Law, to a law under METI jurisdiction, saying that it is not necessary. It became unclear whether a new regulatory system could be decided upon.
At a press conference following the cabinet decision, METI Minister Yasutoshi Nishimura explained, “The basic policy was put together from the perspective of nuclear energy utilization policy and does not include safety regulations, so there is no problem,” and expressed his intention to continue with procedures such as amending related laws. Hajime Matsukubo, executive director of the NPO Nuclear Information and Documentation Office, who also served as a member of METI’s expert panel, commented, “They are forcibly proceeding with the conclusion that they are promoting nuclear power without listening to opposing opinions. This is unacceptable as a method of policy making.
People opposing the Cabinet decision on the basic policy in front of the Prime Minister’s official residence in Nagatacho, Tokyo, on March 10.
◆Attack on the Prime Minister’s Office
On January 10, about 100 people protested in front of the Prime Minister’s official residence in Nagata-cho, Tokyo, after the cabinet approved a basic policy that includes measures to promote nuclear power plants. In the cold rain, they called for “No new nuclear power plants” and “Don’t forget Fukushima. (Nozomi Masui)
The event was organized by the Executive Committee for 10 Million People’s Action to Say Goodbye to Nuclear Power Plants, a citizens’ group. Members of six organizations, including environmental groups and labor unions, took the microphone.
Natsuka Mitsuda, 55, secretary general of FoE Japan, an international environmental NGO, said, “In order for the nuclear industry to survive, future generations will have to bear a heavy burden and risk of accidents. We are firmly opposed to the cabinet decision that ignores the will of the people. Taeko Fujimura, 68, vice chairperson of the National Trade Union Liaison Council, said, “We have learned nothing from the accident at the Fukushima Daiichi Nuclear Power Plant. The operation of aging nuclear power plants is absolutely unacceptable.
Cabinet adopts policy of using nuclear reactors beyond 60-year limit
The No. 3 reactor at Kansai Electric Power’s Mihama nuclear power plant in Mihama, Fukui Prefecture, the first nuclear reactor in Japan to operate beyond 40 years.
Feb 10, 2023
The Cabinet formally adopted a policy on Friday that will allow for the operation of nuclear reactors beyond their current 60-year limit alongside the building of new units to replace aging ones as part of efforts to cut carbon emissions while ensuring adequate national energy supply.
The government’s “green transformation” policy features extensive use of nuclear power along with renewable energy and marks a major policy shift for the country, which suffered a devastating nuclear disaster in 2011. The Cabinet decision follows a meeting in late December at which the policy was agreed upon.
The government also plans to raise about ¥20 trillion ($152 billion) through the issuance of green transformation bonds to boost investment in decarbonization projects, as it estimates public and private investment of over ¥150 trillion will be necessary over the next 10 years.
Bills necessary to implement the new policy were submitted to parliament Friday.
The new policy will effectively extend the amount of time reactors can remain operational beyond 60 years by excluding time spent on inspections and other periods they are offline from consideration when calculating their total service life.
The policy also calls for developing advanced reactors, regarded as safer than conventional ones, and only allowing them to be built within the premises of reactors destined for decommissioning. The government aims to begin operating next-generation reactors in the 2030s.
It also states the central government is responsible for the final disposal of high-level radioactive waste created through nuclear power generation. The issue has been a source of concern among the public and a challenge in advancing nuclear policy.
Economy, Trade and Industry Minister Yasutoshi Nishimura said at a news conference after the Cabinet meeting that the government hopes to expand the areas in which it will conduct first-stage surveys as part of the selection process for the final disposal site.
The new policy stipulates government support for local governments which accept the survey.
Public sentiment turned sour over the use of nuclear power as a national source of energy following the Fukushima No. 1 nuclear disaster in March 2011 that was triggered by a massive earthquake and tsunami. The government had repeatedly said it was not considering building new reactors or replacing existing ones.
But since Russia launched a major invasion of Ukraine in late February last year, a sharp rise in global energy prices has threatened the stable supply of energy for Japan, a resource-scarce country that heavily relies on fossil fuel imports, prompting officials to look into greater use of nuclear power.
Prime Minister Fumio Kishida instructed the government last summer to look into how the country can maximize the use of its nuclear energy facilities most effectively.
Cabinet decides on a policy of “maximum utilization” of nuclear power plants, a major shift from “reducing dependence on nuclear power plants,” enabling nuclear power plants to operate for more than 60 years and promoting rebuilding
Prime Minister’s Office
February 10, 2023
On February 10, the cabinet approved the government’s basic policy for decarbonization, which includes rebuilding next-generation nuclear power plants and extending their operational life beyond 60 years. In addition to renewable energy, the policy also specifies “maximum utilization” of nuclear power plants. After the accident at TEPCO’s Fukushima No.1 nuclear power plant, the government has been advocating a reduction in dependence on nuclear power, but the worsening environment for procuring energy resources due to the crisis in Ukraine and other factors have led to a major shift in energy policy.
The decision was made in the form of the “Basic Policy for the Realization of GX (Green Transformation). Minister of Economy, Trade, and Industry Yasutoshi Nishimura stated, “The public and private sectors will work together to accelerate efforts toward the realization of GX.
After the compilation of the policy in December of last year, a public comment period was held, and approximately 3,300 opinions were received.
The period of operation of nuclear power plants, which after the Fukushima accident was set at “40 years in principle, with a maximum of 60 years,” will be extended to allow operation for more than 60 years, excluding from the calculation the period during which the plants are shut down to respond to the screening process for restarting. The company will also work on the development and construction of next-generation nuclear power plants on the grounds that this will increase safety. (Kyodo)

NRA delays easing reactor rules after one expert objects
Akira Ishiwatari, a commissioner of the Nuclear Regulation Authority, raises opposition to the government’s plan to ease safety regulations for reactors at a meeting on Feb. 8.
February 9, 2023
A Nuclear Regulation Authority panel member objected to the government’s draft policy to lift the 40-year cap on the lifespan of nuclear reactors, forcing official approval to be delayed.
Akira Ishiwatari, one of the five members of the NRA, said at a Feb. 8 meeting that dropping the restriction on reactors’ operation periods at 40 years, in principle, and a maximum 60 years from the nuclear reactor regulation law, is not a “change to make them safer.”
Ishiwatari, a former professor of geology at Tohoku University and head of the Geological Society of Japan, is tasked with studying plant operators’ measures to safeguard reactors from earthquakes and tsunami. He has been on the NRA since 2014.
Under the more stringent reactor regulations introduced in 2013 following the 2011 Fukushima nuclear disaster, the life of a reactor was limited to 40 years, in principle, to enhance the safety of nuclear facilities. But it can operate 20 more years, including the period when they were shut down for safety checks or court injunctions, if found safe to do so by the NRA.
The Kishida administration compiled a plan to ease the rules last month that would allow reactors to serve beyond the maximum 60-year limit by excluding the time when they were offline.
For example, the lifespan of a reactor that remained idle for 10 years would be extended to 70 years in total.
Ishiwatari noted that some reactors have been shut down for many years due to the NRA’s prolonged safety examinations for their restart.
But he expressed concern that excluding the shutdown period from the maximum 60-year rule would lead to the activation of more aged units.
With his objection, NRA Chairman Shinsuke Yamanaka decided to postpone the panel’s approval of the government policy for more discussion on the issue.
A majority of the public opposes the easing of the reactor restrictions.
At the NRA meeting, it was reported that most of the 2,016 opinions received from the public over the government plan were critical.
Still, the NRA initially planned to back the government policy to remove the cap and install a system that would require a reactor to undergo safety checks in under every decade once it reaches 30 years in service.
Cabinet approves a major change in nuclear power plant policy, including new construction and operation beyond 60 years.

On February 10, the Kishida administration approved the “Basic Policy for Realization of GX (Green Transformation),” which includes allowing new construction and operation of nuclear power plants for more than 60 years, at a cabinet meeting. The change in nuclear power policy since the accident at TEPCO’s Fukushima Daiichi Nuclear Power Plant became an official government policy. Related bills will be submitted to the ordinary Diet session.

Public comments on the draft of the basic policy presented in December of last year included many objections to the nuclear power policy, but no major revisions were made.
The basic policy mainly lists policies that should be taken over the next 10 years toward the realization of a decarbonized society in 2050. It clearly states the “maximum use” of nuclear power plants as well as renewable energy. After the accident, the government had stated that it did not envision the construction of new nuclear power plants at this time, but it has now shifted to a policy of working toward this goal.
Specifically, the government will “work on the development and construction” of improved nuclear power plants, which it calls “next-generation innovative reactors,” and will rebuild them on the sites of nuclear power plants that have been decided to be decommissioned. The government will also “consider” building nuclear power plants in areas where there are currently no nuclear power plants.

Regulatory Commissioners object to proposed new rules for nuclear power plant regulation
Akira Ishiwata, a member of the Nuclear Regulation Authority of Japan (NRAJ), expresses his opposition to the draft of new safety regulation rules for nuclear power plants.
February 9, 2023
At the February 8 meeting of the Nuclear Regulation Authority (NRA), committee members voiced their opposition to the draft framework for new safety regulation rules, which would require safety inspections at intervals of no more than 10 years starting from 30 years of operation. The committee members decided not to make a formal decision on that day, and will discuss the issue again next week or later.
Since the end of last year, the Regulatory Commission has been conducting “public comments” to gather opinions from the public on the draft framework. At the meeting, it was reported that 2016 comments had been received, many of which were opposed to the 40-year operation period stipulated in the Nuclear Reactor Regulation Law, but the committee decided that no revisions to the draft were necessary and decided to proceed with the decision as originally proposed.
Regulatory Commission is in the forefront of extending the operation of nuclear power plants.
In response, Akira Ishiwata, a member of the committee in charge of the earthquake and tsunami review, stated, “I am opposed to this proposal,” citing two main reasons.
The first is that the stipulation of an operating period will be removed from the Reactor Regulation Law, which is under the jurisdiction of the Regulatory Commission.
Mr. Ishiwata said, “The mission of the Nuclear Regulation Commission is to protect people and the environment based on scientific and technical findings. This change is not about changing the law based on some new findings. Dropping the operation period from the law (Reactor Regulation Law) is not an alteration to the safety side,” he said.

Proposal to operate nuclear power plants for more than 60 years “cannot be considered a change to the safe side”; Regulatory Commission postpones formal decision due to unusual opposition
February 9, 2023
At its regular meeting on February 8, the Nuclear Regulatory Commission discussed whether to make a formal decision on a new regulatory system for nuclear power plants to operate beyond 60 years, but it decided not to do so due to opposition from Akira Ishiwata, who stated that the proposal “cannot be considered an alteration to the safe side. The matter will be discussed again at the regular meeting next week. It is extremely unusual for the regulatory commission to be divided on such an important matter. (Kenta Onozawa)
◆Public comments: Most oppose the review
The new draft regulation will review the deterioration status of nuclear power plants every 10 years or less, starting 30 years after the start of operation, and if the plant complies with the regulatory standards, the extension of operation will be approved. The proposal was unanimously approved at the regular meeting held last December. On the day of the meeting, the final draft was discussed based on the results of public comments received from the public.
The majority of the 2016 comments received from the public were against the review of the system, but the secretariat of the Regulatory Commission consulted with the regular meeting on whether to make a formal decision on the draft without changing the content of the draft regulation. Of the five committee members, four, including Chairman Shinsuke Yamanaka, voted in favor of the draft, while Commissioner Ishiwata expressed his opposition. Chairman Yamanaka stated that he would not make a decision by majority vote, but would discuss the matter again together with the proposed amendment to the article of the Nuclear Reactor Regulation Law (Reactor Regulation Law) that stipulates the operation period.
At a press conference following the regular meeting, Chairman Yamanaka said, “I think there is a misunderstanding (among Commissioner Ishiwata). I don’t think it is a problem that there are opposing opinions. I would like to deepen the discussion among the committee members.
Last December, the government decided to allow nuclear power plants to operate for more than 60 years by excluding from the number of years of operation the period during which the plants were shut down for restart examinations and judicial decisions. It aims to submit a draft amendment to related laws to the current Diet session. The current provisions in the Reactor Regulation Law regarding the period of operation, which is “40 years in principle, with a maximum of 60 years,” are expected to be deleted and redefined in the Electricity Business Law under the jurisdiction of the Ministry of Economy, Trade and Industry (METI).
◆”Aging nuclear power plants will be operated in the future,” said Akira Ishiwata, a member of the committee.
I am against this proposal. Akira Ishiwatari, a member of the committee, stated his opposition in a firm tone toward the end of the meeting.
This change is not based on new scientific findings. It is not a change for the sake of safety, because the law will drop the period of operation. There is no need for us to amend the law voluntarily.
A geological expert, he has served as a professor at Tohoku University and as a member of the committee since 2014. When it was discovered that geological data had been rewritten during the review of the Tsuruga No. 2 reactor at the Japan Atomic Power Company’s Tsuruga Nuclear Power Plant in Fukui Prefecture, he proposed that the review be suspended. When the secretariat of the Regulatory Commission proposed last November that the Commission hear opinions from electric power companies on the proposed new regulations, he opposed the proposal, saying that it was too early to make a decision. Discussions were postponed.
Under the new government policy, the period of shutdown due to the review will be excluded from the number of years of operation. In most cases, the 10 units currently under review have been delayed due to inadequate explanations from the power companies. Commissioner Ishiwata, who is in charge of the examination of earthquake and tsunami countermeasures, said, “We are not unnecessarily prolonging the examination, but unfortunately it is taking a long time. The longer the review takes, the longer the operation period will be, and the older (aged) nuclear power plants will be in operation in the future.
He expressed strong concern that the more difficult the review process becomes, the more likely it is to encourage the operation of aging nuclear power plants. At the meeting, Chairman Yamanaka explained that “this is a mechanism to ensure that regulations can be implemented no matter what the operating period is like,” but Commissioner Ishiwata did not back down, saying, “My thoughts are as I have stated.

Japan: Cabinet adopts policy of using nuclear reactors beyond 60-year limit

Japan Times 10 Feb 23
The Cabinet formally adopted a policy on Friday that will allow for the operation of nuclear reactors beyond their current 60-year limit alongside the building of new units to replace aging ones as part of efforts to cut carbon emissions while ensuring adequate national energy supply.
The government’s “green transformation” [whaaa..aat?] policy features extensive use of nuclear power along with renewable energy and marks a major policy shift for the country, which suffered a devastating nuclear disaster in 2011. The Cabinet decision follows a meeting in late December at which the policy was agreed upon.
The government also plans to raise about ¥20 trillion ($152 billion) through the issuance of green transformation bonds to boost investment in decarbonization projects, as it estimates public and private investment of over ¥150 trillion will be necessary over the next 10 years……… (Subscribers only] https://www.japantimes.co.jp/news/2023/02/10/national/reactor-limit-extended//
Japan Plans to Dump Fukushima Wastewater Into a Pacific With a Toxic Nuclear History

In December, the U.S.-based National Association of Marine Laboratories also announced its opposition to TEPCO’s plans, publishing a position paper that says “there is a lack of adequate and accurate scientific data supporting Japan’s assertion of safety” while “there is an abundance of data demonstrating serious concerns about releasing radioactively contaminated water.”
BY AMY GUNIA , FEBRUARY 6, 2023,
Pacific Island nations have for decades been grappling with the environmental and health consequences of Cold War-era nuclear testing in the region by the likes of the U.S. and France. Now, they worry about another kind of nuclear danger from neighbors much closer to home.
As concerns over energy security and the desire to transition away from fossil fuels pushes several Asian nations to reconsider once-scrapped nuclear power programs, there is increasing anxiety over how the waste from those facilities—depending on the methods of disposal—might impact the lives of Pacific Islanders.
Notably, in the region, Philippines President Ferdinand “Bongbong” Marcos said in his first address to Congress in mid-2022 that he was open to adding nuclear energy to the country’s energy mix, the Indonesian government said in December it plans to build a nuclear power plant by 2039, and weeks later Japan announced that it plans to ramp up the use of nuclear energy.
Nuclear plants have long been touted as a reliable source of carbon-free energy, though many plants across the world had been shuttered in past decades over worries about the safety of nuclear waste disposal. In this new era of nuclear revival, similar uncertainties abound.
In Japan, one plant that isn’t even operational has become the frontline for the fight between activists seeking safety assurances for waste disposal and operators who are running out of space in on-site tanks to store the wastewater accumulating from keeping damaged reactors cool. Currently, Japan plans to release wastewater from the Fukushima Daiichi nuclear power plant into the Pacific Ocean later this year.
“It’s just horrendous to think what it might mean,” says Henry Puna, the secretary general of the Pacific Islands Forum (PIF), a regional intergovernmental organization that has more than a dozen member countries, including, for example, the Cook Islands, Fiji, Tonga, and Vanuatu. “The people of the Pacific are people of the ocean. The ocean is very much central to our lives, to our culture, to our livelihoods. Anything that prejudices the health of the ocean is a matter of serious concern.”
When a magnitude 9.1 earthquake and tsunami hit off the coast of Japan in 2011, it caused a meltdown at the Fukushima nuclear power plant. Since then, water is being used to cool the damaged reactors and prevent further catastrophe. Now, more than 1.3 million metric tons of radionuclide-contaminated water has been collected on site, and it continues to accumulate, as rain and groundwater seep in. Tokyo Electric Power Company (TEPCO), the operator of the plant, says that the storage tanks take up too much space and hinder decommissioning the plant. Japan initially said that it would begin releasing the water into the ocean in the spring of 2023. Chief Cabinet Secretary Hirokazu Matsuno told the media in January that the release target date is now around spring or summer, which appears to be a postponement, according to the Associated Press, due to construction delays on a pipeline and the apparent need to gain greater public support.
The plan has faced widespread opposition. Japanese fishermen, international environmentalists, and other governments in the region, including China, South Korea, and Taiwan, have all expressed concern. Some of the strongest pushback has come from Pacific Island countries, including from lawmakers, former leaders, regional fisheries management groups, and other organizations. Among those voices is the PIF, which is advocating for more time to deal with questions and concerns. Earlier this year, the PIF appointed a panel of independent global nuclear experts to help inform its members in their consultations with Japan and TEPCO. The experts have stressed that more data are needed to determine the safety of the water for disposal.
“We think that there is not enough scientific evidence to prove that the release is safe, environmentally, healthwise, and also for our economy in the Pacific,” says Puna, who is also the former Prime Minister of the Cook Islands. Until more information is shared and evaluated, he asks that Japan “please defer the discharge of the water.”
……………………………. there appears to be a major disconnect between TEPCO and others, including the PIF panel of experts—who say that they’re concerned with the adequacy, accuracy, and reliability of the data backing up the decision to release the water.
Robert H. Richmond, a research professor and the director of the Kewalo Marine Laboratory at the University of Hawaii at Manoa, who is one of the panel experts, tells TIME that “the critical, foundational data upon which a sound decision could be made was either absent or, when we started getting more data,” he says, “extremely concerning.” He also casts doubt on if the IAEA is in the best position to assess the risks. “They’re an agency that has a mandate to promote the use of nuclear energy,” says Richmond, “and our mandate is to look after the people, the ocean, and the people who depend on the ocean. And our unanimous conclusion … is that this is a bad idea that is not defended properly at this point, and that there are alternatives that Japan should really be looking at.”
“One of the biggest surprises to me was the fact that the data was so sparse,” says Ferenc Dalnoki-Veress, scientist-in-residence and adjunct professor at the James Martin Center for Nonproliferation Studies at the Middlebury Institute of International Studies at Monterey, who is also on the PIF panel of experts. “There were prolonged gaps in data collection, which suggests that the matter may not have been given the level of attention and importance it deserved.” He adds that only a fraction of the tanks had been sampled, and only a handful of some 60 isotopes were typically measured in the samples—fewer than he would expect for this kind of assessment. (TEPCO says that the analysis done on a sample of tanks so far is just to assess the water’s condition in storage but that, after the purification process, further measurements will be taken on all the treated water before discharge to ensure that only that which meets sufficient standards of safety is released into the ocean).
Some still fear the safety of the treated water, and the far-reaching implications if it’s dumped into the ocean. Puna points out, for example, that the waters of the Western and Central Pacific Ocean produce much of the world’s tuna. If the tuna were to be impacted, it would cause major problems for Pacific nations, for which fisheries are a significant source of income, as well as for consumers globally.
In December, the U.S.-based National Association of Marine Laboratories also announced its opposition to TEPCO’s plans, publishing a position paper that says “there is a lack of adequate and accurate scientific data supporting Japan’s assertion of safety” while “there is an abundance of data demonstrating serious concerns about releasing radioactively contaminated water.”
……………………………………. A scarring past and a new path forward
Other nuclear plants across the globe have released treated wastewater containing tritium. Rafael Mariano Grossi, the IAEA’s director general, said in 2021 that Japan’s plan is “in line with practice globally, even though the large amount of water at the Fukushima plant makes it a unique and complex case.”
But Pacific Island nations have particular reason to be anxious. There is a noxious legacy of nuclear testing in the region, and other countries have historically treated the Pacific as a dumping ground for their waste. The U.S. conducted 67 nuclear tests in the Marshall Islands between 1946 and 1957—and disposed of atomic waste in Runit Dome, where it’s still stored. That testing led not only to forced relocations, but also to increased rates of cancers. Today there is concern that the dome is leaking and that rising sea levels might impact its structural integrity. France also conducted 193 nuclear tests from 1966 to 1996 at Moruroa and Fangataufa atolls in French Polynesia.
…………………….. Rather than let dumping wastewater into the ocean become the norm, at this juncture for nuclear energy, some say it’s an opportunity to explore different ways of doing things. The panel of PIF experts has proposed several alternative solutions, including treating the water and storing it in more secure tanks to allow the tritium time to decay, or using the treated water to make concrete for use in projects that won’t have high contact with humans.
“This is not the first nuclear disaster and by no means is it going to be the last,” says Richmond. “This is an opportunity for Japan,” he says, “to do the right thing and to invest time, effort, and money into determining and coming up with new ways of handling radioactive waste and setting a new trajectory.”
Death and Japan’s nuclear shelter salesman

Khrushchev once speculated that the survivors of the apocalypse would envy the dead. I agree.
LEO LEWIS, https://www.ft.com/content/5dbd0e08-5eec-4486-a1ba-fe1948d11159— 5 Feb 23
The “doomsday clock” maintained since 1947 by the Bulletin of Atomic Scientists is many things. An index of our gossamer proximity to annihilation; a metaphor for the human paradox of progress and regression; a near-drained reservoir of hope that the gods will spare us from ourselves. And, of course, a superb marketing tool for any half-decent nuclear shelter salesman.
The Bulletin’s January 24 decision to move the hands of its doomsday clock closer to midnight (signifying global catastrophe) than they have ever been before should, logically, give the bunker business a recession-defying sales spike. The collective shrug it will actually get is more profoundly alarming.
For Hiroki Nakajima, the marketing director of shelter-maker World Net International (WNI), these are comparatively good times. North Korean ballistic missile tests and China’s rising military power, he says, have driven Japanese shelter sales significantly higher than in the past. The fear factor soared after Vladimir Putin invaded Ukraine and started issuing explicit nuclear threats. WNI historically used to sell only a couple of $80,000 premium shelters a year; in 2022 that shot up to a still modest 25 — hardly a nation gripped with fear.
Nakajima, whose best customers are the very wealthy and very nervous, says he will consider listing the company on the Tokyo Stock Exchange “as society’s needs require”. He delivers his nuclear shelter sales pitch from a medium-sized warehouse with models arranged by size, blast resilience and interior decor. I am shown into one with eggshell blue padded walls and, optimistically given the post-Armageddon broadcasting constraints, a wall-mounted TV.
We are in the smallish seaside town of Yaizu, a pretty fishing port that looks back on to a snow-capped Mount Fuji and whose placidness contrasts effectively with the mental picture of the horrors that would make a shelter purchase value for money. Nakajima’s marketing strategy includes judicious repetition of the phrase “your whole family will die” wherever appropriate; mostly as the certain outcome of any attempt at self-preservation other than buying a WNI shelter.
As efforts to induce apocalyptic terror go, it is valiant stuff. But he is talking to someone who grew up in Britain in the 1980s: someone who has had his wits scared out of him by far, far more proficient fearmongers. Set against (among others) Threads, The War Game, When the Wind Blows and the Protect and Survive public information films, Japanese shelter marketing feels almost upbeat. As Cold War children we hummed pop songs that were more chillingly referential to nuclear obliteration than the WNI website. And that was when the Doomsday clock was set further from midnight than it is now.
But Nakajima is not without support in his bid to set out the risks. Last month, the Japanese government began considering for the first time what a shelter subsidy scheme might look like, suggesting that its assessment of the nuclear threat has advanced from the general to the specific. Should such a subsidy emerge, says Nakajima, sales could be 100 times what they are now.
I sit for some time in WNI’s cramped showcase shelter, imagining the circumstances that might bring me to this bunker if I ever owned one: the mass extinction beyond its sturdily engineered walls, the irradiated cinders of civilisation blown against its air filter intake, the endless weeks cocooned with whichever loved ones made it in time, mourning those who did not. Nikita Khrushchev once speculated that the survivors of such a war would envy the dead. I agreed, and Nakajima quietly lost a customer.
The faint feeling of absurdity in WNI’s showroom points, obliquely, to a problem with the doomsday clock. Arguably the most potent symbol of humanity’s collective need to change tack, the clock is now set at just 90 seconds to midnight but seems to have lost its capacity to terrify at a time when we should be more terrified than ever before.
For while the clock is most closely associated in the public mind with the threat of nuclear war, it has long been a broader metric of imperilment from all human-made global disaster — a spectrum of risk ranging from climate change, and the denial of it, to microscopic autonomous robots.
The trouble with the clock is that, where once it was a paramount siren, it is now merely one of many alarms telling us that we are doomed. Under cover of that surfeit of fear, the clock has now gone pretty much as far as it can without being right. That is something none of us — even those with the best shelter $80,000 will buy — can afford to see proved.
