Ministry’s action plan drops nuclear policies set after 3/11
Local officials want new reactors to replace the two retired units at the front of Kansai Electric Power Co.’s Mihama nuclear plant in Fukui Prefecture.
November 29, 2022
The industry ministry proposed building new nuclear reactors to replace retired ones and effectively extending their operating lives beyond 60 years, a reversal of policies set after the 2011 Fukushima nuclear disaster.
The proposals were presented to the ministry’s advisory council, the Nuclear Energy Subcommittee, at a meeting on Nov. 28 as a draft action plan for the Kishida administration’s slogan to “make maximum use of nuclear energy.”
Although many subcommittee members endorsed the proposals, some members said not enough time was spent on discussing such a major change in energy policy.
Prime Minister Fumio Kishida in August issued a directive to a special government panel tasked with decarbonizing Japan to review the current nuclear energy policy.
The government has maintained that “for now,” it does not expect construction of new nuclear plants or a replacement of any reactor.
Because of opposition expected from local governments, the plan also did not propose building nuclear plants in areas that have never hosted such facilities or adding new reactors to existing plants.
But under the action plan, the Ministry of Economy, Trade and Industry states that construction of new reactors “will begin with those replacing retired ones,” giving utilities the green light to build reactors to take the place of those being decommissioned.
The ministry is also seeking “advanced light water reactors” as replacement units, expecting them to start operating in the 2030s. They will each come with an estimated price tag of at least 500 billion yen ($3.57 billion).
Such reactors have enhanced safety features and are an extension of current nuclear technologies, the ministry said.
The action plan also pushes for a system that will effectively extend the life cycle of reactors beyond the maximum of 60 years set under rules adopted after the 2011 triple meltdown.
It suggests that often lengthy periods when reactors are offline for examinations by the Nuclear Regulation Authority on whether they meet standards for restarts be excluded from the 60-year limit.
In addition, the time frame should not include periods when reactor operations are suspended because of lawsuits, the ministry said.
Under those proposals, a reactor that has been idle for 10 years for those reasons could operate for up to 70 years since it first went into service.
The proposed exclusions from the 60-year limit have been criticized as “taking the teeth from” the rigorous reactor regulations set in 2013.
One subcommittee member said the exclusions are “akin to ditching the lessons learned from the Fukushima accident.”
The action plan also called for a new system to provide grants to local governments that promote the use of recycled nuclear fuel at facilities in their jurisdictions.
This is meant to give some leverage to the nation’s trouble-plagued nuclear fuel cycle policy.
Although the action plan represents a sweeping policy change, it does not directly deal with a slew of challenges that have remained unsolved for decades.
For example, it is unclear when the nuclear fuel reprocessing plant under construction in Rokkasho, Aomori Prefecture, a key component in the nuclear fuel cycle program, will go into operations.
Under the program, plutonium retrieved from spent nuclear fuel from across Japan will be recycled as fuel for use at nuclear plants.
The completion date of the reprocessing plant has been pushed back 26 times so far. Around 14 trillion yen has been invested in the project.
Another big headache for the central government is securing a final disposal site for highly radioactive nuclear waste from nuclear power plants across the country.
Two small municipalities in Hokkaido have shown an interest in hosting such a storage facility in exchange for generous grants.
But the Hokkaido governor is opposed to the plan. And no other local governments in Japan have come forward as potential final disposal sites.
The ministry’s action plan did not list any specific proposals to resolve these issues. It merely said: “The state should bolster efforts to gain the understanding” of the public to the nuclear policy.
Japan studies plan to extend life of 60-year-old nuclear plants
Nov 28, 2022
Japan will consider keeping some nuclear reactors operating beyond a current 60-year limit as the country focuses increasingly on atomic power as a solution to an ongoing squeeze on energy supply.
Officials are studying a plan to exclude periods when reactors were offline from an existing limit on their lifespan, which would allow some facilities to operate for longer, according to a document released Monday by a trade ministry panel. Reactors are often halted for years to allow the nation’s nuclear watchdog to perform inspections, or as a result of legal challenges.
Following the 2011 Fukushima nuclear disaster, which was triggered by a massive earthquake and tsunami, Japan introduced stricter safety standards limiting the operation of nuclear reactors to 40 years in principle.
But operation for an additional 20 years is possible if safety upgrades are made and a reactor passes screening by regulators.
The proposal to allow operations beyond the 60-year limit comes as Japan’s public and government shift back in favor of nuclear power, despite experiencing one of the worst atomic meltdown disasters. The import-dependent country has this year grappled with more expensive fossil fuel prices as a result of Russia’s war in Ukraine, along with a weak yen, and seen its stretched power grid put under severe pressure.
The government has repeatedly asked people to take steps to limit their electricity consumption, by using fewer appliances or cutting back on heating.
In August, Prime Minister Fumio Kishida said the government will explore developing and constructing new reactors, and that it will also aim to restart seven more idled reactors from next summer.
The trade ministry proposals also call for new, next-generation nuclear reactors to be built at sites where existing units will be decommissioned.
Japanese manufacturers have announced plans to develop next-generation reactors this year. Mitsubishi Heavy Industries is jointly developing an advanced light water reactor with four other Japanese power producers, while a venture between Hitachi and General Electric is also reported to be developing a new reactor model.

Expert panel full of proponents of nuclear power plants to discuss direction on March 28th, extending operation period and developing next-generation models, rushing to conclusion on “Prime Minister’s directive.
Basic policy subcommittee discusses extending the operational period of nuclear power plants in Kasumigaseki, Tokyo.
November 27, 2022
The Ministry of Economy, Trade, and Industry (METI) will present its direction on measures to utilize nuclear power plants, including the extension of the operating period of nuclear power plants, which is stipulated as “40 years in principle, with a maximum of 60 years,” and the development and construction of next-generation nuclear power plants, at the “Nuclear Energy Subcommittee,” a meeting of experts on November 28. Discussions will reach their final stage about three months after Prime Minister Fumio Kishida ordered the committee to study the issue in August. However, the committee did not solicit opinions from the public before reaching a conclusion, and its deliberations were noticeably more hasty than past energy policy debates. （The discussion has been held in a very slow pace compared to past energy policy debates.)
◆Draft government policy at several subcommittee meetings
Of the 21 members of the Atomic Energy Subcommittee, which discusses nuclear energy policy, only two, including Hajime Matsukubo, executive director of the NPO Nuclear Data and Information Office, have made negative statements about nuclear power at recent meetings. In the discussion on extending the operating period, many committee members called for removing the maximum 60-year limit, and at the meeting on March 28, METI is expected to push for a proposal to exclude from the number of years of operation the period during which a nuclear power plant is shut down to undergo a review before it can be restarted, without removing the limit in consideration of public outcry.
The contents of the Nuclear Energy Subcommittee’s deliberations will be discussed by the Basic Policy Subcommittee, which brings together expert panels on energy policy, and the conclusions of the subcommittee will serve as a draft of the government policy.
At the meeting on March 15, Ms. Chisato Murakami, an advisor on consumer affairs, commented, “The use of nuclear power plants will not directly lead to an end to the tight power supply and demand situation. I would like to propose that we take time to deepen the national debate.” She objected to the way the discussion was proceeding, but no other opinions were expressed calling for a reconsideration.
The subcommittee has met twice so far. The committee is expected to hold one or two more meetings before the end of the year to reach a conclusion, after which public comments will be sought.
◆Energy Basic Plan to be discussed 17 times and opinions solicited via the Internet
The previous energy policy discussions were different.
In the discussion of the “Sixth Basic Energy Plan,” a medium- to long-term guideline for energy policy formulated last October, subcommittee meetings were held 17 times over a period of 10 months. In addition, an opinion box was set up on the website during the discussions in order to listen to the opinions of the public at large. The opinions received were submitted as materials to each of the subcommittee meetings for consideration. In total, about 640 opinions were collected, with about 300 calling for a nuclear power phase-out, while about 80 supported the promotion of nuclear power.
At that time, members of the subcommittee expressed the opinion that extending the operational period of nuclear power plants and building new plants were necessary to realize a decarbonized society by 2050, but this was not explicitly stated in the basic plan. The policy of “reducing dependence on nuclear power plants as much as possible,” which came to be stated after the Fukushima accident, was also maintained.
◆Ministry of Economy, Trade, and Industry (METI) official: “The directive to reach a conclusion by the end of the year cannot take too much time.
The government has been stressing the use of nuclear power plants against the backdrop of the recent tight power supply and demand and soaring fuel prices. However, the development of next-generation nuclear power plants, for example, will take a long time and will not be a quick fix, so there is no need to reach a hasty conclusion. Even after Murakami pointed out this contradiction at the subcommittee meeting, a METI official told the interviewer, “We cannot take too much time because [Prime Minister Kishida] has instructed us to reach a conclusion by the end of the year. We will come up with a direction as soon as possible.
Mr. Matsukubo commented, “This is a heavy-handed way of proceeding, not listening to the public and having the Council of Eminent Persons decide what the government wants to do. The government’s policy of making nuclear power a given may narrow the scope for the introduction of renewable energies in the future.

Machinery manufacturer Nippon Steel Works subsidiary confirms 449 cases of fraud, including falsification of inspection resultsNippon Steel Works subsidiary confirms 449 cases of fraud, including falsification of inspection results
Machinery manufacturer Japan Steel Works announced that its subsidiary in Muroran, Hokkaido, Japan, repeatedly falsified or fabricated the inspection results of its products, and that a total of 449 irregularities were identified. These included products for nuclear power plants.
November 14, 2022
Machinery manufacturer Nippon Steel Works, Ltd. announced that its subsidiary in Muroran City, Hokkaido, Japan, has repeatedly falsified or fabricated inspection results for its products, and that a total of 449 cases of fraud have been confirmed. The company apologizes and says it will consider disciplinary action against those involved.
After an internal report uncovered irregularities in the rewriting of inspection data for parts at Muroran-based subsidiary Nippon Steel M&E, Nippon Steel established a special investigation committee made up of outside lawyers in May of this year, and has been conducting an investigation.
The company released a report summarizing the results of the investigation on April 14, stating that 449 cases of falsification and fabrication were confirmed.
The subsidiary is a major manufacturer of products used in nuclear power plants, and 20 of the fraudulent products were related to nuclear power plants.
In addition, the company has stated that none of the products involved are used in Japan for nuclear power plants.
The report also pointed out the causes of the irregularities, including a dysfunctional management system and a lack of awareness of compliance.
President Matsuo said, “We are deeply sorry for the inappropriate behavior in nuclear power products.
In response to the investigation report, Toshio Matsuo, president of Nippon Steel Corporation, issued a comment saying, “I would like to express my deepest apologies again for the inconvenience and concern we have caused you.
The report also stated, “We take the fact of the failure of the self-cleansing function and the recommendations of the special investigation committee very seriously and sincerely, and we will work to reform our systems and culture to prevent recurrence and restore confidence in our company. We are committed to reforming our systems and culture to prevent recurrence and restore trust in our company.

Japan looks to finalize nuclear reactor service extension by year-end
This Feb. 13, 2021 photo taken from a Mainichi Shimbun helicopter shows the Fukushima Daiichi nuclear power plant in Fukushima Prefectur
November 8, 2022
TOKYO (Kyodo) — Japan’s industry ministry is considering extending the lifespan of nuclear reactors to beyond the current 60 years with ambitions to finalize the plan by the end of the year, in a bid to cut carbon emissions and ensure stable energy supplies threatened by Russia’s war in Ukraine, sources familiar with the matter said Tuesday.
The Ministry of Economy, Trade and Industry is looking to extend the number of years nuclear power stations can remain open by considering screening periods, necessary for stricter plant safety operations, as separate from the total service life, which could allow nuclear reactors to operate for longer. During safety checks, the nuclear plants are not operational.
A ministry panel is set to discuss extending the service life of the nuclear power stations in such a way as a main scenario among other options, with plans to finalize their decision by the end of the year, the sources said.
Under the current safety rules, the Nuclear Regulation Authority limits nuclear reactors’ service period to 40 years in principle. If approved by the regulatory body however, the period can be extended by up to 20 years.
The panel will also look at scrapping the 60-year lifespan, as well as maintaining the current rules as two alternative options, in case the proposal is found not to be viable.
Prime Minister Fumio Kishida said in August that Japan will push ahead with the use of nuclear power, citing the plan as an option to achieve net-zero emissions and secure a stable electricity supply.
Japan relies heavily on fossil fuel imports for power generation, with its energy self-sufficiency rate standing at 12.1 percent as of fiscal 2019, lower than many other developed countries.
Nuclear power plant operators must pass the tougher regulations to restart their reactors after a nationwide halt which occurred after the Fukushima nuclear disaster of March 11, 2011, which was caused by a massive earthquake and tsunami. Only a handful of reactors in Japan have since resumed operations, while the public remains concerned over their safety.
Some utilities face prolonged screening processes by the NRA. More than nine years have passed since the safety examinations of Hokkaido Electric Power Co.’s Tomari nuclear power plant began, for example.
The electric power industry has urged more than 60 years of service will be safe provided appropriate maintenance operations are guaranteed.
The safety watchdog proposed earlier this month that the safety of nuclear plants aged 30 years or older, regardless of whether a reactor lifespan is extended, be checked at least once a decade to obtain approval for their continued operation.

NRA risks losing its reputation as neutral nuclear watchdog body
Members of the Nuclear Regulation Authority hold a meeting Nov. 2 in Tokyo’s Minato Ward.
November 5, 2022
The Nuclear Regulation Authority (NRA) has started working on legal revisions to effectively eliminate the limit on the operational life span of nuclear reactors.
The NRA appears to be responding to growing calls for the “revival” of nuclear power generation within the government and the business community. The NRA was set up as a highly independent nuclear safety watchdog in line with lessons gleaned from the 2011 Fukushima nuclear disaster. It should not forget its original mission.
The legal life span of a nuclear reactor is 40 years in principle but can be extended to 60 years at a maximum.
But the Ministry of Economy, Trade and Industry (METI), acting at Prime Minister Fumio Kishida’s behest, has proposed increasing the life span of reactors. Acting in tandem with the government’s move, the NRA instructed its Secretariat, a government agency, to review the current rules.
In a recent meeting on this issue, the NRA Secretariat presented a proposal which would require reactors that have been in service for 30 years to undergo inspections for signs of degradation at intervals of 10 years or less to win permission for continued operation. As long as they keep passing these periodical inspections, they can run beyond the 60-year limit.
The NRA is expected to work out, possibly by the end of the year, an outline of a draft revision of the Nuclear Reactor Regulation Law for the extended operations of nuclear plants.
The 40-year cap was a rule established under a bipartisan agreement reached through Diet debate that focused on the bitter lessons from the triple meltdown at the Fukushima No. 1 nuclear power plant in 2011. This rule, along with the suspension of new construction and expansion of nuclear power plants, played an important role in reducing the nation’s dependence on atomic energy, a policy goal adopted by the government. The rule must not be changed without national debate after only 10 years.
The NRA argues that whether to extend the legal life of reactors is a policy decision concerning the use of nuclear power that is outside its mandate. That means the NRA’s mandate is to ensure proper regulations of nuclear power generation according to the government’s policy.
At a glance, this position appears to be based on the principle of the separation of nuclear safety regulation from the government’s policy to promote nuclear power generation. But it is, in effect, regulation in line with promotion.
Nuclear power plants inevitably wear down over time. There are many plant parts that were not designed to be replaced. As the initial design philosophy for reactors has become outdated, the risk of unexpected problems and malfunctions increases. The 40-year rule was partly aimed at avoiding such unclear and unpredictable risks.
Extended life spans will inevitably increase the burden of inspections and raise the cost of electricity generated by aging reactors due to costs incurred by taking the necessary measures to pass inspections. This also raises questions about whether extended operations of reactors will make economic sense.
The NRA claims the regulations for reactors that have run for 30 years or longer would become “far more rigorous than now” under the proposed change. Some NRA experts have said the new system should make it harder for older reactors to pass inspections. Others have pointed out the importance of responding to the risks posed by natural disasters like earthquakes, tsunami and volcanic eruptions.
But the specifics of the new regulations and operational rules remain unclear. The ongoing policy debate on the issue, clearly driven by arguments for promoting nuclear power, raises doubts about whether the government could develop a new regulatory system that can win the support of the residents and administrations of host communities and the public as a whole.
To prevent another nuclear tragedy, it is vital for the NRA to remain solidly committed to maintaining its independence. Serious doubt about its independence would deliver a huge blow to its credibility with society.
If its independence is undermined, the NRA might be unable to resist future political pressure for relaxing the safety regulations or safety inspections of aged and risky reactors.
The NRA must realize that the situation poses a critical test of its commitment to its core mission as the nuclear safety watchdog.
Magnitude 5 earthquake jolts Fukushima; ‘no issues’ at nearby nuclear plants
‘No issues’ at nearby nuclear plants…. So they claim as usual, everything is always fine in Fukushima Daiichi….
Oct 21, 2022
A strong earthquake with an estimated magnitude of 5 jolted northeastern Japan on Friday afternoon.
The quake, which was revised downward from magnitude 5.1, occurred at a depth of about 30 kilometers off the coast of Fukushima Prefecture around 3:19 p.m., according to the Meteorological Agency.
The quake measured a lower 5 on Japan’s seismic intensity scale to 7 in the town of Naraha and 4 in the towns of Hirono, Tomioka, Okuma and Futaba.
According to the Secretariat of the Nuclear Regulation Authority, no issues have been reported at Tokyo Electric Power Company Holdings’s Fukushima No. 1 and No. 2 nuclear plants in the prefecture.
The No. 2 plant straddles Naraha and Tomioka, while the No. 1 plant, the site of the 2011 meltdowns following the Great East Japan Earthquake and tsunami, straddles Okuma and Futaba.
In a location close to the epicenter of Friday’s quake, a 7.4-magnitude temblor occurred at the depth of about 12 kilometers on Nov. 22, 2016, causing tsunami that reached up to 144 centimeters high at Sendai Port in the neighboring prefecture of Miyagi.
Unlike the 2016 temblor, which also registered up to lower 5 on the Japanese scale, Friday’s quake did not cause tsunami because it occurred at a greater depth and was smaller in scale.

Editorial: Japan’s push to extend nuke reactor life past 40 yrs doesn’t add up
October 13, 2022 (Mainichi Japan)
The administration of Prime Minister Fumio Kishida has begun considering eliminating the “40-year rule,” or the principle that nuclear reactors should be decommissioned after four decades in service.
Japan’s Nuclear Regulation Authority (NRA), which is responsible for the law enforcing the 40-year principle, has given its blessing to this new policy. The Ministry of Economy, Trade and Industry, in charge of the stable supply of electricity, will now decide how a reactor’s operating life should be determined.
The 40-year rule was introduced after the meltdowns at Tokyo Electric Power Co. Holdings (TEPCO)’s Fukushima Daiichi Nuclear Power Station in March 2011. And since then, the idea that nuclear reactors will run for 40 years and no more has become firmly entrenched.
The rule was also Japan’s declaration that it was committed to moving away from nuclear dependence by decommissioning aging reactors one by one, reflecting upon the seriousness of the disaster.
A policy shift from the 40-year rule would require national consensus. It is unacceptable for the administration to leave legal revisions regarding safety up to the industry ministry — which spent decades promoting nuclear power — and essentially dictate a return to atomic power. It is also inconsistent with the government’s own Basic Energy Plan, which clearly states that Japan’s dependence on nuclear power will be reduced.
In August this year, Prime Minister Kishida abruptly announced a policy of building new nuclear power plants and restarting existing reactors. This was based on the belief that atomic power is indispensable for both a stable electricity supply and to decarbonize Japan’s energy system.
One obstacle to this is those existing reactors’ service time. Most of them have been in operation for 30 years, and should the 40-year rule be strictly applied, more than 10 reactors will have to be decommissioned by 2030.
The electricity sector and the industry ministry hope to extend those reactors’ operational life to save money, arguing that “40 years is just a guideline with no clear scientific basis.” However, data on accident risks at aging atomic power plants is limited. After the Fukushima Daiichi meltdowns, it was decided that 11 reactors in Japan would be decommissioned because it would cost too much to implement the safety measures needed to keep them running.
NRA head Shinsuke Yamanaka stated, “We will establish a system that enables strict regulation no matter what the operational life may be.” But is there enough knowhow, and a sufficiently robust review system, to maintain effective regulation?
Even if the rules are changed to allow nuclear reactors to stay online regardless of how long they’ve been in service, this does not guarantee that restarts will go smoothly. In addition to potential nuclear accidents, municipalities hosting the plants have deep-seated concerns about information disclosure and evacuating residents in case of a disaster.
What is needed is an energy policy that makes use of the lessons learned from Fukushima Daiichi. Forcing through political decisions without convincing the Japanese public will only stoke their distrust of nuclear power.

Extending legal life of nuclear reactors places safety at risk
October 7, 2022
The industry ministry’s plan to allow extending the operational life span of nuclear reactors beyond 40 years raises concerns about ensuring the safety of aging reactors.
The cap was a rule established under a bipartisan agreement reached through Diet debate that focused on the bitter lessons learned from the accident at the Fukushima No. 1 nuclear power plant in 2011. It must not be casually changed after only 10 years.
The Ministry of Economy, Trade and Industry has started considering revisions to related laws to stretch the life span of reactors, which is set at 40 years, in principle.
Prime Minister Fumio Kishida, who is keen to expand the use of nuclear power, instructed the ministry in August to consider necessary steps for extending the life span, along with other measures, such as restarting more idled reactors and building new types of reactors.
The 40-year rule is one of the key elements of the new stricter safety standards introduced after the Fukushima disaster. This has also played an important role for gradually lowering the nation’s dependence on atomic energy by requiring older reactors to be mothballed.
The METI and the power industry claim extending reactor operations would help ensure stable energy supplies. They stress that the 40-year cap is not strictly a question of the technical life of the plant based on hard science.
Their arguments are deeply flawed and flimsy. They raise many questions from the standpoints of both the nation’s energy strategy and safety regulations.
To be sure, Russia’s invasion of Ukraine has caused fossil fuel prices to soar, provoking anxiety about short-term power supplies. But changing the 40-year rule would not lead to an immediate increase in the number of operational reactors.
However, the step would put the nation on course to remain heavily dependent on nuclear power for the long term.
That is not the way for a nation that has yet to have a viable plan for the final disposal of radioactive waste from nuclear plants and is highly prone to natural disasters to try to secure the long-term stability of energy supplies.
The proposed extension could also lead to a radical change in a basic safety principle. The core guiding principle for nuclear power policy established after the Fukushima triple meltdowns requires a separation between promotion and regulation.
The actions of the METI, a champion of nuclear power promotion, to lead a policy initiative to change nuclear safety rules is tantamount to bringing the safety regime back to the pre-Fukushima era.
The stance of the Nuclear Regulation Authority (NRA), the nuclear safety watchdog, is also baffling.
The NRA did not take exception to the METI’s plan. It said it is not in a position to comment on whether an extension of the life span of reactors should be allowed because it is a policy decision concerning the way nuclear power is used.
Although the NRA insists that it will rigorously scrutinize and assess the safety of aging reactors individually, it is doubtful whether the regulator will be able to confirm their safety.
Limiting the life of reactors is closely linked to ensuring safety.
During the 2012 Diet deliberations on the legal revisions to set the 40-year rule, the minister in charge of nuclear power policy cited the estimated useful life of equipment used as a key factor behind the 40-year limit.
If the NRA fails to discuss the validity of the 40-year rule based on technical evaluations and simply endorses the proposal as a policy decision concerning the use of nuclear power, it is neglecting its duty as an independent regulatory entity.
Such a sneaky change in the rules will chip away at the effectiveness of the nuclear safety regulations. Both the METI and the NRA should change their stances toward the issue.
Japan set to extend maximum lifespan of nuclear plants beyond 60 yrs
Nuclear I love you forever. Despite of the still ongoing Fukushima nuclear disaster, the Japanese government is still in love with nuclear….
Oct 5, 2022
The head of Japan’s nuclear regulator said Wednesday a rule that limits the operating life of nuclear power plants to a maximum of 60 years is expected to be removed from the country’s regulations.
The possible change is in line with Prime Minister Fumio Kishida’s goal of extending the lifespan to reduce carbon emissions and provide a stable electricity supply. Still, public concern over the safety of nuclear facilities is deep-seated in Japan following the 2011 Fukushima disaster.
“We can assure you that strict regulations will never be compromised,” Shinsuke Yamanaka, chairman of the Nuclear Regulation Authority, said at a press conference.
Following the nuclear crisis triggered by a massive earthquake and tsunami, Japan introduced stringent safety standards limiting nuclear reactors’ service period to 40 years in principle.
However, that period can be extended once by 20 years if safety upgrades are made and a reactor passes the regulation authority’s screening.
The Ministry of Economy, Trade and Industry said Wednesday it would determine the plants’ operational service per a regulation under its jurisdiction, and its plan was approved by the regulatory body.
The NRA plans to create a system to ensure each aging nuclear power plant’s safety.
Nuclear Industry Association of Japan (NIAJ) proposes that “new and additional nuclear power plants and rebuilding of nuclear power plants should be clearly stated in national plans
July 22, 2022
On July 22, the Japan Atomic Energy Industries Association (JAEA), an association of companies involved in nuclear power generation, released a proposal calling for the construction of new nuclear power plants and their replacement (rebuilding). The association said this is the first time it has issued such a proposal. The association calls for new nuclear power plants to be built or rebuilt to maintain the nuclear power supply chain.
Public distrust of nuclear power plants has been deep-rooted in the wake of the accident at TEPCO’s Fukushima Daiichi Nuclear Power Station. The government has stated that it “does not envision” new or rebuilt reactors at this time, and a freeze on nuclear power plants continues in Japan.
However, the crisis in Ukraine has led to…

Japan’s Nuclear Power Plants in 2022
June 29, 2022
As of June 2022, 10 nuclear reactors at six power stations have been given the go-ahead to restart in Japan but only 4 reactors are currently in operation. Despite local governments agreeing to restart the reactors, some have not yet become operational due to the time required to implement safety measures and complete other construction work.
Prior to the Great East Japan Earthquake of 2011, 54 nuclear reactors were in operation in Japan, supplying approximately 30% of the country’s electric power. However, the disaster at the Fukushima Daiichi Nuclear Power Plant was a drastic blow to nuclear power’s reputation, leading to increased distrust and unease toward the energy source.
As of June 2022, only 10 reactors have been restarted with local approval at the following six power stations: Ōi, Takahama, and Mihama (Kansai Electric Power Company), Genkai and Sendai (Kyūshū Electric Power Company), and Ikata (Shikoku Electric Power Company). These plants based in western Japan all use pressurized water reactors, which are different from the boiling water reactors at the Fukushima Daiichi Nuclear Power Plant.
Boiling water reactors at the Onagawa (Tōhoku Electric Power Company), Kashiwazaki-Kariwa (Tokyo Electric Power Company), Tōkai Daini (Japan Atomic Power Company), and Shimane (Chūgoku Electric Power Company) nuclear power stations have all been approved under the new regulatory standards, but none have received the green light to restart.
In total, 21 nuclear reactors have been decommissioned since the 2011 Great East Japan Earthquake.

Japan’s nuclear power plants are “not designed for war” and if attacked by missiles, “radioactive materials will be scattered
March 9, 2022
At a meeting of the House of Representatives’ Committee on Economy, Trade, and Industry on March 9, Chairman Toyoshi Sarada of the Nuclear Regulatory Commission said, “There is concern that radioactive materials will be spread” in the event of a missile attack on a nuclear power plant in Japan. We do not believe that this can be avoided with the current facilities. This was in response to Makoto Yamazaki of the Democratic Party of Japan’s Constitutional Democratic Party of Japan, who asked a question in response to an attack on a nuclear power plant by Russian forces that invaded Ukraine.
The government has explained that it is taking counterterrorism measures for nuclear power plants in Japan, but has not clearly stated the danger of a military attack. Mr. Sarada explained to the METI Committee that “we do not envision an armed attack due to a conflict between two countries (in terms of safety) in our examinations,” he said. If a nuclear power plant is occupied, “the entire control of the plant will be seized. After that, any situation is inevitable.
Defense Vice Minister Makoto Oniki responded that improvements in missile technology have made it more difficult to intercept missiles and that “we will not rule out any options, including an enemy base attack capability, and will consider them in a realistic manner. Yamazaki insisted, “When we consider the risk of attacks from earthquakes, terrorism, and wars such as this one, we still have to close nuclear power plants. (Nobuko Ohno)

Japan now has 16 reactors that meet requirements
November 11, 2020
Japan now has 16 reactors at nine nuclear power plants that have cleared government requirements adopted after the 2011 Fukushima accident.
The No.2 reactor at Tohoku Electric Power Company’s Onagawa plant in Miyagi Prefecture, and the reactor at Japan Atomic Power Company’s Tokai No.2 plant in Ibaraki Prefecture were affected by the 2011 earthquake and tsunami. Tokai No.2 has yet to win local consent to restart.
Tohoku Electric’s Higashidori plant in Aomori Prefecture, also a part of the Fukushima disaster zone, is undergoing screening by the Nuclear Regulation Authority.
Reactors at Tokyo Electric Power Company’s Fukushima Daiichi and Daini nuclear plants are set to be scrapped.
Reactors that have already been put back online are: the No.1 and No.2 units at the Sendai plant in Kagoshima Prefecture; the No.3 and No.4 units at the Genkai plant in Saga Prefecture; the No.3 and No.4 units at the Takahama plant in Fukui Prefecture; the No.3 and No.4 units at the Ohi plant, also in Fukui Prefecture; and the No.3 unit at the Ikata plant in Ehime Prefecture.
The Sendai and Genkai plants are operated by Kyushu Electric Power Company, the Takahama and Ohi plants by Kansai Electric Power Company and the Ikata plant by Shikoku Electric Power Company.
Suga: Japan has no plan for new nuclear plants
Nov. 4, 2020
Prime Minister Suga Yoshihide has ruled out new nuclear plants or new reactors for Japan at this point, as the country aims to reduce its greenhouse gas emissions to net zero by 2050.
Suga was answering questions from Constitutional Democratic Party leader Edano Yukio in the Lower House Budget Committee on Wednesday.
Edano urged an early end to Japan’s reliance on nuclear power. He noted that many people who were forced to evacuate after the 2011 accident at the Fukushima Daiichi nuclear plant are still unable to go back home. He said it is inconceivable to build a new nuclear plant.
Suga said he has declared that Japan would become carbon neutral by 2050, despite differing views within his Liberal Democratic Party. He stressed the government has no plan to build any nuclear plant.
In the same committee, Economy, Trade and Industry Minister Kajiyama Hiroshi said his ministry will continue efforts to upgrade safety so that nuclear power would remain an option in 2050. He said the efforts will include development of new technologies, such as advanced innovative reactors.
