Fukushima: Japan attempts to safely remove nuclear fuel from crippled reactors

More than a decade after the second-worst nuclear disaster in history, engineers want to construct a huge water-filled tank around one of the damaged reactors and carry out underwater dismantling work.

The proposal would permit experts to deploy robots to more closely examine the condition of the crippled reactor

September 22, 2022

Nuclear experts pondering the safest way to decommission the three crippled reactors at the Fukushima Daiichi atomic energy plant have devised a new plan to recover highly radioactive debris at the site, with even anti-nuclear campaigners giving the proposal their qualified support.  

They warn, however, that the situation at the plant — on the northeast coast of Japan— remains precarious more than a decade since three of the six reactors suffered meltdowns after an offshore earthquake of magnitude 9 triggered a series of powerful tsunamis.  

In their latest annual strategy report on progress at the plant, experts at the Nuclear Damage Compensation and Decommissioning Facilitation Office (NDF) have proposed the construction and filling with water of a massive concrete tank to completely enclose one of the reactor buildings. 

The water would act as a shield to prevent radiation from escaping into the surrounding environment and give engineers more space, in which to operate heavy equipment to dismantle and remove the outer shell of the reactor building.

That, in turn, would permit experts to deploy robots to more closely examine the condition of the reactor, as well as the fuel that has escaped and pooled in the building’s basement levels.  

The plan was presented to the government at a meeting in Iwaki, just south of the plant, in early September, during which NDF President Hajimu Yamana explained the benefits. 

Safe from radioactivity 

“No radioactive materials would be swirling up underwater, so there would be almost zero impact on the outside,” Yamana told the Asahi newspaper.

NDF experts plan to construct a massive concrete tank arond one of the reactor buildings

He emphasized, however, that the proposal was in the initial stages and no final decision had been taken. If it worked, however, then the same strategy could be deployed to help in the decommissioning of the remaining two damaged reactors at the facility. 

“I cannot say anything for sure yet,” Yamana said. “We are still in the very, very early stages of the concept study. There are still a lot of things to study as the attempt would be the first of its kind in the world.”

Hajime Matsukubo, secretary-general of the Tokyo-based Citizens’ Nuclear Information Center, remains a vocal critic of the Japanese government’s insistence on the need for atomic energy, but agreed that the NDF plan appeared to offer a number of benefits for the decommissioning process. 

“The work cannot go ahead without the water shield because it would expose workers to dangerously high levels of radiation so this idea for the construction of a tank around one of the reactors is positive,” he told DW.  

“But that does not mean that I am not concerned,” he said. “It will be very difficult to construct this tank, to make sure it does not leak, and it will be very expensive and take more time, of course.”

Another earthquake 

Another concern that has been a constant since the March 2011 disaster is the possibility of another major earthquake or tsunami damaging the tank and potentially exposing radioactive debris to the air.

“We have already seen what long-term exposure to salt water at the site does to metal and other materials, and if there was another major tremor then that could very easily affect the tank and even see it collapse,” Matsukubo said. “To me, that is the biggest worry.”  

He also questioned why it had taken the Tokyo Electric Power Company (TEPCO), decommissioning experts, the government and Japan’s nuclear regulators more than a decade to think up the plan. It is likely that the delay will further extend the schedule and total cost of rendering the site safe.

Government estimates put the cost of decommissioning at 8 trillion yen (€56 billion, $55.3 billion), although that figure may increase if new complications crop up, while the work will probably continue for another 30 years.  

Kazuto Suzuki, a professor of science and technology policy at Tokyo University, agreed that the new approach to the decommissioning of the reactors “seems to be a good one, but the problem will be in the execution.” 

“I’m not an expert, but I can see problems with leaks — as they have already experienced from the tanks holding contaminated water at the site — and then that water escaping into the sea,” he said. “This is a really big issue for the people still living in the region and they have to be able to guarantee a safe level of water within the tank surrounding the reactor.” 

Seismic concerns 

There are also concerns about the stability of the ground that the tank will stand on due to the immense weight it will have to bear, Suzuki pointed out.  

He was less worried, however, about the possibility of another earthquake wreaking further havoc at the site.  

“Concern about another earthquake is legitimate, but we have to remember that the original damage to the Fukushima plant was almost entirely the result of the tsunami, not the earthquake,” he said.  

“I actually believe that Japan can be quite proud of the sophisticated anti-seismic technology that is incorporated into all buildings here, but especially our nuclear plants,” Suzuki said.

“I am confident that thanks to the lessons we have learned at Fukushima already, the impact of another earthquake on the walls of a tank around a reactor would be factored into the construction process.”

40,000 signatures submitted to TEPCO and METI opposing release of treated water from nuclear power plants

Katsuhito Fuyuki, President of Miyagi Co-op, submitted signatures opposing the discharge of treated water to Junichi Matsumoto (right), head of TEPCO’s treated water countermeasures.

September 21, 2022
On September 21, representatives of consumers’ cooperatives in Iwate, Miyagi, and Fukushima prefectures and Miyagi fishery cooperatives submitted about 40,000 signatures opposing the discharge of treated water from TEPCO’s Fukushima Daiichi Nuclear Power Plant into the ocean. On March 21, representatives of consumer cooperatives in Miyagi and Fukushima prefectures and Miyagi fishermen’s cooperatives submitted approximately 40,000 signatures to TEPCO and the Ministry of Economy, Trade and Industry opposing the discharge of treated water from TEPCO’s Fukushima Daiichi Nuclear Power Plant into the ocean. They demand that instead of discharging the water into the ocean, it be treated in a different way that can be understood by the concerned parties and the public.
 According to a person in charge of the co-op, they have been collecting signatures online and in writing since June 2021, and together with those already submitted, they have collected about 21,000 signatures nationwide. The total number of signatures, including those already submitted, amounted to about 21,000 nationwide.
 Katsuhito Fuyuki, president of the Miyagi Co-op, explained the reason for his opposition at the TEPCO headquarters: “We are concerned about the negative impact on the resumption of full-scale fishing operations in Fukushima, the fishing industry in Miyagi, and the local economy.

The sea is not Japan’s dustbin, nor the Pacific Ocean its sewer: Chinese FM

Foreign Ministry Spokesperson Mao Ning Photo: Ministry of Foreign Affairs

Sep 19, 2022

Chinese Foreign Ministry on Monday once again called on Japan to stop its dubious and irresponsible plan of dumping Fukushima nuclear-contaminated water into the sea, as the radioactive substance in the nuclear-contaminated water, although it had already been treated through a filtration system, was once tested to be two times higher than the discharge standard.

According to Kyodo News, the Tokyo Electric Power Company (TEPCO), which is in charge of construction of the facility to be used for releasing the nuclear-contaminated water, said on Thursday that the company found the level of radioactive substance Strontium 90 as high as three times of Japan’s national standard, even though the samples on July 28 had been treated through a filtration system called ALPS (Advanced Liquid Processing System).

The report came after the repeated claim of both the Japanese government and TEPCO that nuclear-contaminated water is “safe” to be dumped into the ocean because it would go through the multi-nuclide removal system ALPS and radioactive substances such as Strontium 90 and Carbon 14 that cause genetic mutation in the ecosystem can be reduced to a “safe” level.

“I’ve noticed related media report and this proves the exact rationality of international community’s concern over the reliability of Japan’s data, the efficacy of the treatment system, and the uncertainty of environmental impact,” said Chinese Foreign Ministry spokesperson Mao Ning on Monday’s regular press conference.

The sea is not Japan’s dustbin, nor the Pacific Ocean its sewer, Mao emphasized, saying the Japanese government is extremely irresponsible for forcing through its disposal plan and the construction of underwater pipeline to dump the nuclear-contaminated water from Fukushima nuclear power plant into the ocean given doubts in the plan and unsettled international concerns.

Mao once again urges Japan to deal with the nuclear-contaminated water in a scientific, open, transparent and safe manner on the basis of negotiations with neighboring countries and international institutions.

Despite concerns and opposition from within and neighboring countries including South Korea and China, TEPCO started construction of facility on August 4 for dumping the nuclear-contaminated water after Japan’s nuclear regulator approved its discharge plan in late July.

[Interview] Japanese anti-nuclear activist says fishers’ consent is crucial for Fukushima water release

Steel-framed tunnels being constructed at the Fukushima Daiichi Nuclear Power Plant

September 20, 2022

What exactly is going on off the coast of Japan’s Fukushima Daiichi Nuclear Power Plant?

Hideyuki Ban, co-director of the Citizens’ Nuclear Information Center in Japan, says the Fukushima tunnel for offshore dumping of the water is unlikely to be up to scratch

On Aug. 4, the Japanese government and the Tokyo Electric Power Company (TEPCO) began construction on the underwater tunnel that will be used to release treated water from the Fukushima nuclear power plant into the ocean.

Their plan is to use the Advanced Liquid Processing System (ALPS) to reduce the amount of radioactive material in the contaminated water, after which the treated water would be released into the ocean. Currently, they are at the soil preparation stage. Concerns are being raised not only in neighboring countries but also within Japan itself, pointing out that the ALPS’s ability to remove radioactive material is still unclear, and that the release of the contaminated water is being pushed ahead even though the amount of water to be released has yet to be decided.

On Sept. 6, TEPCO even opened the construction site for the underwater tunnel, 80 meters of which was already complete, to the public, suggesting that it has no intention of backing down from its plan to release the contaminated water during the first half of next year.

During his interview with the Hankyoreh, Hideyuki Ban, co-director of the Citizens’ Nuclear Information Center in Japan, commented that TEPCO and the Japanese government made a written promise not to release the contaminated water without the consent of interested parties, adding that he doubted they would be able to earn the consent of fishers and environmental groups. Even technologically speaking, Ban said it was unlikely that the construction would pass the necessary safety tests upon completion.

An internationally acclaimed anti-nuclear activist, Ban has been serving as the co-director of CNIC, a private Japanese think tank working toward “a society that doesn’t rely on nuclear power” through research and studies into Japan’s nuclear policy, for the past 24 years. The interview took place on Sept. 13 over email.

■ One month into the construction of the tunnel

Hankyoreh (Hani): It’s been a month since construction for the underwater tunnel began. What stage is it currently in?

Hideyuki Ban: Excavation work for the underwater tunnel began on Aug. 4. At the same time, construction related to the stirrer inside the storage tank containing the contaminated water, the transfer pump for the treated water, and the embankment for seawater intake commenced as well. TEPCO has said it would provide “timely updates” regarding the progress of the construction, but its website doesn’t offer much information as to how it’s going. Two local governments that have jurisdiction over the nuclear power plant as well as Fukushima Prefecture consented to the construction ahead of time. The next day, civic groups protested in front of the Fukushima Prefecture office building. Civic groups are still continuing their movement against the release of the contaminated water. Plus, fishers’ groups are also firmly expressing their opposition.

Hani: The plan is to release the contaminated water into the ocean in June next year — do you think that’s likely?

Ban: For the contaminated water to be released into the ocean, consent from fishers’ groups comes above all else. TEPCO and the government promised in writing not to release the contaminated water without the consent of fishers’ groups. However, fishers’ groups are proposing special resolutions opposing the release of the contaminated water into the sea at their general meetings this year. I doubt [TEPCO and the Japanese government] will be able to earn their consent. The same goes from the technological perspective. For the contaminated water to be discharged next June, not only do various constructions currently in progress need to be completed as scheduled, but other hurdles should be jumped over, such as a safety test that would come afterward. I believe the technology is not enough to pass such tests. There are other practical issues. Problems on the site, such as the increasing number of COVID-19 patients among workers at the Fukushima Daiichi plant, will probably delay the construction as well.

■ Beneath the water’s surface The construction site TEPCO revealed to the Japanese media on Sept. 6 indicated that the construction is progressing quickly. According to Japanese public broadcaster NHK’s footage, the steel-framed concrete tunnel round in shape is big enough for people and equipment to pass through. Inside, a dozen or so green drainpipes stretch to the distance. The tunnel has gotten roughly 80 meters closer to the ocean since construction began. TEPCO is extending the underwater tunnel, which starts from the drainage system for nuclear reactors No. 5 and No. 6 at the Fukushima Daiichi plant, by 16 meters each day. The tunnel’s outlet will be created 1 kilometer (0.62 miles) from land. TEPCO previously stated that its goal was to complete construction of the facilities “by spring next year,” but said that completion could take place in summer, depending on weather conditions.

Hani: There were many controversies related to the underwater tunnel even before its construction began, such as when International Atomic Energy Agency (IAEA) Director General Rafael Grossi took the side of TEPCO in April, saying he was satisfied with the progress Japan made during its preparation process.

Ban: The IAEA’s report says that “the government or the regulatory body are required to provide information to, and engage in consultation with, parties affected by its decisions and, as appropriate, the public and other interested parties.” The report defines “interested parties” as “individuals or organizations representing members of the public; industry; government agencies or departments whose responsibilities cover public health, nuclear energy and the environment; scientific bodies; the news media; environmental groups; and groups in the population with particular habits that might be affected significantly by the discharges, such as local producers and indigenous peoples living in the vicinity of the facility or activity under consideration.” It’s hard to understand why the IAEA determined progress had been made without properly evaluating the current situation, which hardly indicates “consultations” have been sufficiently carried out.

Hani: But the Japanese government is saying the IAEA task force’s criticism enabled it to reinforce the contents of its implementation plan and radiological impact assessment, which it is citing as the reason the plan to release the contaminated water should be pushed ahead.

Ban: TEPCO’s November 2021 report on the radiation effects of the release of ALPS-treated water into the ocean on humans and the environment indicates that the effects of tritium, which Japanese regulations acknowledge as having negative effects on the human body, were not reflected. It’s hard to say the contents have been dutifully reinforced. The report doesn’t even mention the total amount of radioactive material that would be released, which is a figure civil society has been demanding. It’s a big problem that how much of each nuclide would be released wasn’t revealed, as that information would precede any kind of agreement or discussions that would take place between the government [and interested parties] ahead of the release of the contaminated water. The IAEA should also demand that TEPCO and the Japanese government announce the total amount [of radioactive materials] it expects to release.

■ Action needed now

Hani: How unsafe do you think it is to release the contaminated water into the ocean?

Ban: The contaminated water currently contains 64 different radioactive nuclides, including tritium, which can enter the human body and cause internal exposures. The government and TEPCO plan to use the ALPS over and over until the amount of radioactive material in the contaminated water has been reduced to a level fit for release to the ocean. However, the contaminated water will be released for over 30 years. Additionally, risk assessments presume the contaminated water will evenly spread across the ocean and become diluted, but in reality, it will accumulate in specific regions underwater or in seafood. This will ultimately lead to the radiation of people who eat seafood.

Hani: The release of the contaminated water has moved from the “preparation stage” to the “implementation stage,” in a sense.

Ban: Yes. Concerns about radiation caused by radioactive material and the voices of those worried about negative effects on the tourism industry, as well as the fishing, forestry and agriculture industries, are growing louder and louder.

Hani: What are some things people can do right now?

Ban: People should be vocal so that the plan to release the contaminated water into the ocean can be stopped immediately. The Japanese government and TEPCO say nuclear power plants around the world regularly emit tritium. While such everyday tritium emissions will ultimately lead to radioactive contamination, the bigger problem is that the world has never seen a case in which 64 nuclides including tritium were released into nature simultaneously, as the release of the contaminated water from Fukushima will. The water will keep on being discharged for the next 30 years while the total amount of radioactive material being released remains a mystery. Pollution of the marine environment caused by radioactive material emitted by the water should not be overlooked. By Hong Seock-jae, staff reporter

TEPCO to Decide on Price Hike Based on Resumption of Nuclear Power Plant Operations, Kashiwazaki-Kariwa Unit 7, for Businesses from FY2023

Kashiwazaki-Kariwa Nuclear Power Plant of Tokyo Electric Power Co.

September 16, 2022
 On September 16, Tomoaki Kobayakawa, president of TEPCO Holdings, announced that the company is considering raising electricity rates for businesses on the assumption that the Kashiwazaki-Kariwa Unit 7 nuclear power plant (in Niigata Prefecture) will be restarted in fiscal 2023. President Tomoaki Kobayakawa of TEPCO Holdings announced on September 16 that the company plans to calculate the range of the price increase based on the assumption that the Kashiwazaki-Kariwa Unit 7 nuclear power plant (Niigata Prefecture) will be restarted in 2023. The company aims to reduce the burden on contracted companies by about 200 billion yen. He also explained, “We aim to resume operations as soon as possible, but we have no concrete timetable for this.
 The target is the “high-voltage” and “special high-voltage” rate plans used by commercial facilities and factories, with approximately 170,000 contracts. The company plans to raise the rates so that the market price of electricity can be reflected in the rates. At the same time, a system will be introduced to calculate the cost of nuclear power plants, which have lower generation costs, on the assumption that they will operate for nine months a year, thereby curbing the size of the price increase.
 At the press conference, President Kobayakawa explained, “We are not specifying the timing of the restart. Even if we are not able to restart operations, we will curb the price increase. Although this will cause TEPCO’s bottom line to deteriorate, he said, “We will make efforts to reduce (costs). (Kyodo)

A series of defective products at a French MOX fuel plant Abnormal nuclear reaction at a nuclear power plant

September 3, 2022

A series of defective products have been found at the Mellox plant in southeastern France, which manufactures fuel for plutonium thermal power generation, in which plutonium is burned in nuclear power plants. In addition, an abnormal increase in nuclear reactions has also been observed at some nuclear power plants that are conducting plu-thermal power generation. What in the world is going on?

 The plant also manufactures fuel for the Japanese market. No problems have been found so far with the fuel for the Japanese market, but production has been delayed, and future product deliveries are now unpredictable.

 Plutonium is extracted from spent nuclear fuel from nuclear power plants through chemical processing (reprocessing). Plutonium is mixed with uranium in the case of pressurized-water nuclear power plants that conduct plutonium thermal power generation, and baked into pellets, cylindrical grains about 8 mm in diameter. This is called mixed uranium-plutonium oxide fuel (MOX fuel). In the case of a pressurized-water nuclear power plant that conducts plutonium thermal power generation, approximately 320 pellets are stacked inside fuel rods, and another 260 fuel rods are bundled together to form a fuel assembly (approximately 4.1 meters in height).


Highly Difficult Homogenization

 It is difficult to uniformly mix plutonium and uranium. According to ASN data and other sources, “plutonium spots,” dense clumps of plutonium, were found in the fuel pellets produced at the MELOX plant. Plutonium spots were found in the fuel pellets manufactured at the MELOX plant.

 On the other hand, a phenomenon in which the amount of neutrons, which indicate a nuclear reaction, increases more than expected near the upper and lower ends of MOX fuel rods was confirmed at a French nuclear power plant conducting a plutonium thermal operation.

 According to ASN, the combination of this plutonium mass problem and the two anomalies of partially elevated nuclear reactions was predicted to “raise questions about the integrity of the fuel, depending on the circumstances of the accident.

 According to Chihiro Uesawa, 56, an engineering specialist at the NPO Nuclear Information and Data Center (Nakano Ward, Tokyo), concerns are that the fuel could melt or the tubes covering the fuel could break. When plutonium is used as fuel, it has been pointed out that there is a possibility of a localized increase in nuclear reactions. This has become apparent,” Uesawa said.

New submersion method in consideration for Fukushima debris cleanup

The Fukushima Daiichi nuclear complex is seen on Feb. 9, 2022. From left, the No. 4, No. 3, No. 2 and No. 1 reactors.

September 2, 2022

TOKYO (Kyodo) — The operator of the Fukushima Daiichi nuclear power plant, which suffered core meltdowns in 2011, is considering a new submersion method for removing radioactive fuel debris that would wholly encase a reactor building in a water-filled, tank-like structure, a source close to the company said Thursday.

Conceptual breakthroughs with the method, whose advantages include using water’s ability to interrupt radiation and thereby provide a safer working environment, have made it a promising candidate for the cleanup of the defunct nuclear plant, according to the source close to Tokyo Electric Power Company Holdings Inc.

But with no proven track record in the nuclear field, investigations are ongoing into future technological issues and costs, among other contingencies. The source said it could “require advanced technology to stop water leaking out and become a huge construction project.”

Were it to go ahead, the process from building to actual debris removal would be lengthy and would likely affect total decommissioning costs, currently pegged at about 8 trillion yen ($57.45 billion).

In the aftermath of the March 2011 Great East Japan Earthquake and tsunami, nuclear fuel cooling processes failed at the Fukushima plant’s reactors 1 through 3, causing the fuel to melt and resolidify into radioactive debris mixed with concrete, metal and other materials present in the reactors.

Debris removal is the operator’s most challenging issue in the Fukushima plant cleanup. Some 880 tons of the radioactive waste material is estimated to have been created by the nuclear meltdown across the three reactors.

The new submersion method, which is currently expected to be applied to the No. 3 reactor, would involve building a strong, pressure-resistant structure, such as a ship’s hull or a plane’s body, completely encapsulating the reactor, including underground.

The structure could then be filled with water, and removal work would take place from the top.

The operator initially considered a similar method to fill the reactor’s containment vessel with water. But the idea was abandoned due to potential difficulties fixing holes in the structure and the possibility it would increase workers’ exposure to radiation.

Preparations are being made to include the new submersion method in the 2022 edition of a strategic plan for decommissioning to be compiled by the state-backed Nuclear Damage Compensation and Decommissioning Facilitation Corp., which is helping the operator scrap the reactors.

In the case of the No. 2 reactor, preparations remain under way for its debris removal via a dry method, involving extracting the material without filling the reactor with water. The NDF intends to keep it as a potential option in its strategic plan.

While the No. 2 reactor’s cleanup was slated to begin this year, on Aug. 25, the government said removal work would be delayed a further 12 to 18 months to ensure safety and reliability.

The government and the power company are operating under a plan to complete debris removal and finish decommissioning work sometime between 2041 and 2051.

Amid the extensive cleanup in Fukushima, the Japanese government said on Aug. 24 that it is considering the construction of the next generation of nuclear plants amid an increasingly fraught energy supply environment and the country’s dependency on imported natural resources.

As Japan builds nuclear dumping facilities, Pacific groups say ‘stop’

September 1, 2022

Pacific civil society groups are calling on Japan to halt its plans to dump radioactive nuclear wastewater into the Pacific Ocean.

Earlier this month the Japanese government started building facilities needed for the discharge of treated, but still radioactive, wastewater from the defunct Fukushima nuclear power plant.

In a joint statement, civil society groups, non-governmental organisations and activists described the Fumio Kishida Government’s plans as a fundamental breach of Pacific peoples’ right to a clean, healthy and sustainable environment.

Joey Tau from the pan-Pacific movement Youngsolwara Pacific said this breaches Pacific peoples’ rights to live in a clean environment.

Tau told Pacific Waves the Pacific Ocean is already endangered and Japan’s plan will have devastating impacts.

“We have a nuclear testing legacy in the Pacific. That continues to impact our people, our islands and our way of life, and it impacts the health of our people.

“Having this plan by Japan poses greater risks to the ocean which is already in a declining state.

“The health of our ocean has declined due to human endured stresses and having this could aggravate the current state of our region.

“And also, there are possible threats on the lives of our people as we clearly understand in this part of the world, the ocean is dear to us, it sustains us,” Tau said.

Tau said both the opposition in Vanuatu and the president of the Federated States of Micronesia have expressed serious concerns at Japan’s plans, and the Pacific Islands Secretariat this year has appointed an international expert panel to advise the Forum Secretary-General and national leaders.

The Northern Marianas’ House of Representatives has also condemned Japan’s plan to dump the nuclear waste.

Tau said the plans should not proceed without the Pacific people being able to voice their concerns and being better advised.

Fukushima Plants Showing ‘Unusual Growing Patterns’ as Residents Return

One more spin doctor well at work: despite biologist Tim Mousseau’s many fieldtrips to study very precisely the Fukushima radiation’s effects on flora and fauna, an unknown radiobiologist Carmel Mothersill comes out on Newsweek to minimize the risks of the well existing radiation effects on location stating that ‘there is a low risk to people and pets.’

An artwork titled “FUTABA”, a part of the Futaba Art District project is seen on a wall of a shuttered store on August 31, 2022, in Futaba, Fukushima, Japan.

August 31, 2022

Japan’s Fukushima, the site of the world’s second-worst nuclear disaster, is showing “unusual growing patterns” among vegetation in the area because of the radiation contamination.

In 2011, the Fukushima Daiichi nuclear power plant lost power during a tsunami and earthquake that hit Japan’s Pacific coast. This caused systems in three reactors to fail and the cores to overheat. Nuclear material then bored holes in each reactor, causing radiation to leak. This resulted in a series of explosions and a catastrophic nuclear disaster. The event is second only to Chernobyl as the worst nuclear disaster.

Over 300,000 people were forced to evacuate their homes, and an exclusion zone had to be created. Slowly, following remediation, areas have opened up again, meaning people can return. Recently, the town of Futaba lifted its evacuation order.

Tim Mousseau, a professor of biological sciences at the University of South Carolina and a radiation expert, told Newsweek that a “vast region near the power plant” is still “significantly contaminated” but that levels are much lower than they used to be. However, the effects of radiation continue to be seen in the plants in the area, he said.

“There have been a few studies of the plants showing effects of the radiation. For example, it has been shown that Japanese fir trees show unusual growth patterns similar to that observed for pine trees in Chernobyl,” Mousseau said. “Such effects are still open for study, as they are preserved in the growth form of the plant/tree as long as it is still living.”

He continued, “Many areas are still contaminated above levels that most would consider safe for people to live, although most of the region is now relatively safe for short visits.”

Carmel Mothersill, a radiobiologist and the Canada research chair in environmental radiobiology, said that remediation efforts have also affected the area’s vegetation.

“The biggest disruption to the environment was the remediation effort where all vegetation was removed and up to a meter of soil was also taken off to clean it up. But the damage to forests and meadows is terrible,” she said.

“The disruptions to everyday life caused by the accident were permanent for many of the residents, and this is unlikely to change soon for the most affected regions of Fukushima,” Mousseau said. “This is not so much because of persistent radiation per se but also because much of the infrastructure was damaged or destroyed and has deteriorated over the past decade.”

Mousseau also said that the ongoing effects of the contamination and “other human disturbances” remain largely unknown, as “research in the region has dropped off dramatically in the past years because of COVID and Japan’s restrictions on visitors from outside the country.”

“Assuming Japan removes travel restrictions, more research will be conducted,” he said.

While some areas are opening back up to the public, most of the Fukushima area remains evacuated, Mothersill said.

“People are nervous and not happy to go back,” she said. But where people are living, radiation levels are very low, ‘meaning there is a low risk to people and pets.’

Midnight countdown held as evacuation order on Fukushima town lifted after 11 yrs

One of the organizers of the “okaeri project” event waves his hand after opening a door set up in front of JR Futaba Station in Futaba, Fukushima Prefecture, on Aug. 30, 2022.

August 30, 2022

FUTABA, Fukushima — People shouted, “Welcome back!” at the stroke of 12:00 a.m. on Aug. 30 to celebrate the lifting of evacuation orders here, 11-plus years after townspeople were barred from returning following the Fukushima Daiichi nuclear plant meltdowns.

The town of Futaba was one area designated as “difficult to return” due to fallout from the plant, which the town cohosts with the neighboring municipality of Okuma, Fukushima Prefecture. All Futaba residents were forced to evacuate to other parts of Japan after the March 2011 nuclear disaster at the power station run by Tokyo Electric Power Company Holdings Inc.

After 11 years and five months, the town has been deemed habitable once more, with the establishment of a “Specified Reconstruction and Revitalization Base.” And to celebrate, resident volunteers organized the “okaeri (welcome back) project” event in the town center in front of Futaba Station, on the JR Joban Line. A countdown was held, and when the clock struck 12, organizers opened a pink wooden “door of hope” as the people there yelled, “Welcome back!”

About 2,000 candles were lit at the venue on the night of Aug. 29, creating a magical atmosphere. Futaba Mayor Shiro Izawa told the crowd, “I will dedicate myself to reconstruction work, so that it (Futaba) will become a town where people will be happy to come back to.”

Evacuation order finally lifted for Fukushima nuclear plant town

The town of Futaba, which hosts the crippled Fukushima No. 1 nuclear power plant. An evacuation order for the town was lifted on Tuesday for the first time since the March 2011 disaster.

Aug 30, 2022

Fukushima – An evacuation order in a town hosting the crippled Fukushima No. 1 nuclear power plant was lifted Tuesday for the first time since the March 2011 disaster 11 years and five months ago, as the municipality prepares for the return of some of its residents.

The order for the Fukushima Prefecture town, which hosts the Tokyo Electric Power Company Holdings Inc. complex, was imposed after the massive earthquake and tsunami hit the country’s northeast, triggering reactor meltdowns and making the area uninhabitable due to high radiation levels.

Futaba is the last municipality to see an evacuation order lifted among 11 municipalities subject to such orders in the wake of the disaster. Although residents are now allowed to return home, over 80% of the municipality, by acreage, remains designated as “difficult-to-return” zones.

The parts reopened for habitation are located near JR Futaba Station in the town’s previously downtown area and its northeast, where many commercial and public facilities, such as the Great East Japan Earthquake and Nuclear Disaster Memorial Museum, are located.

With relatively low radiation levels, people had been allowed to enter the northeastern area since March 2020 but not to reside there.

As of late July, 3,574 people from 1,449 households, or over 60% of the town’s population, were registered as residents of the two areas accounting for just 15% of Futaba’s total area.

But the number of residents who participated in a preparatory program started in January, allowing them to return temporarily, totaled just 85 people from 52 households.

Following the disaster, most of the town’s residents were evacuated outside the prefecture, along with the town office’s functions. A number of them have since settled outside the town.

While Futaba aims to increase its population to 2,000 by around 2030, a survey of residents last year found that 60.5% had decided not to return, far exceeding the 11.3% who expressed a desire to return.

As for areas other than those that are reopening or scheduled to reopen, the government plans to decontaminate individual locations after confirming that residents intend to return. Futaba and Okuma, a neighboring town to the south that also hosts the crippled power station, are expected to start such work in fiscal 2024.

Although the government said last August it is aiming for the return of residents to areas outside reconstruction and revitalization bases by the end of the decade, the prospects are unclear as areas covering over 300 square kilometers in seven municipalities of the prefecture are designated as difficult-to-return zones.

In Okuma and Futaba, the return of such residents is likely to occur around fiscal 2025 or 2026 at the earliest, considering the time needed for infrastructure building, according to a government official.

Earlier this month, Futaba Mayor Shiro Izawa asked industry minister Yasutoshi Nishimura to “show a road map toward decontamination of the entire area” when he visited Fukushima after assuming the ministerial post.

Fukushima Gov. Masao Uchibori also pointed out that “the steps and scope of decontamination, as well as how to treat the homes and land of those who do not wish to return, have not been worked out.”

The evacuation order was lifted a day after Futaba celebrated the reopening of a residential police box located approximately 3 km northwest of the nuclear plant in the municipality.

The police box, which will house one officer, was shuttered immediately after the nuclear disaster.

“I would like to support the town by keeping the peace here so residents can return feeling secure,” said Hirotaka Umemiya, 40, as he began his duties in the town.

A separate ceremony was held Saturday for the opening of Futaba’s new town office, which was temporarily located in the neighboring city of Iwaki, with its operations set to start Sept. 5.

Three nuclear reactors on the Okuma side of the Fukushima No. 1 complex suffered meltdowns, while the two reactors on the Futaba side was unscathed.

The government is planning to “promote” nuclear power plants…but there are so many difficulties to overcome before this can be realized, and there are doubts about the assurance of safety and security

August 25, 2022
 The government aims to make a major change in its nuclear energy policy, which has denied the construction of new nuclear power plants since the accident at TEPCO’s Fukushima Daiichi Nuclear Power Station on August 24. The government also plans to consider extending the operating periods of existing nuclear power plants again and to further promote their restart. The government is moving forward with the use of nuclear power plants because of the tight power supply and demand caused by the crisis in Ukraine. However, there are serious doubts about the safety and security of nuclear power plants, and it is not clear whether the public will understand this. (The government is now considering the use of nuclear power plants.)
The government is clearly stating that it is “considering” the construction of new and additional nuclear power plants…The government is promoting the extension of the operation period and the restart of a total of 17 reactors.


◆Next generation nuclear reactors” – Technology not yet established
 We will discuss all options for a stable energy supply. We will discuss all options for a stable energy supply and will not rule out the construction of new reactors. Yuji Iida, director general of the Economic and Industrial Policy Bureau of the Ministry of Economy, Trade and Industry (METI), emphasized this before the Green Transformation (GX) Executive Conference, which was held on March 24 to discuss decarbonization policies.
The “Basic Energy Plan” approved by the Cabinet last October did not mention the construction of new nuclear power plants, and successive prime ministers have repeatedly stated that it was not envisioned at this time. Conscious of public sentiment in the aftermath of the nuclear accident, the government has avoided going into the issue.
 The new plants to be considered this time are not existing nuclear power plants, but next-generation models, such as nuclear power plants with improved accident countermeasures and small reactors. Although the government emphasizes safety, many of these next-generation reactors are still in the process of being tested overseas, and it is difficult to say that they have been established as commercial power generation facilities.
 One official at an electric power company commented, “We don’t have the capacity to build new reactors when we can’t even restart existing nuclear power plants. The first step is to operate the current nuclear power plants and restore their technological capabilities.


◆ Extension of operating period: Regulatory Commission not optimistic
 In 2013, after the Fukushima accident, the law was amended to set the operating period of nuclear power plants at 40 years in principle, and to allow for a one-time extension of 20 years. The law was amended in 2013 after the Fukushima accident to allow for a one-time 20-year extension of the 40-year operating period. Four reactors were approved by the Nuclear Regulation Authority (NRA), of which Kansai Electric Power’s Mihama Unit 3 (Fukui Prefecture) has restarted.
 If the units are operated for more than 60 years, which would mean a re-extension, the law may need to be revised again. At a press conference on March 24, Chairman Toyoshi Sarada of the Regulatory Commission said, “Detailed technical discussions are needed. In the U.S., operation for 80 years is permitted, but Mr. Sarada pointed out that “Japan has many earthquakes, and we should not be dragged down by foreign countries.


◆ Seven new reactors restarted → Inadequate anti-terrorism and evacuation plans hindering operations
The government has also set a target of restarting seven reactors at five nuclear power plants that have yet to be restarted, although they meet the new regulatory standards, sometime after next summer or winter.
 In April of last year, the regulatory commission ordered a de facto ban on the operation of TEPCO’s Kashiwazaki Kariwa Nuclear Power Station in Niigata Prefecture because of a problem with a faulty intrusion detector that had been left unattended. The order was not lifted until the plant was found to be in an improved condition, and its inspections have continued.
 Furthermore, Niigata Prefecture has made its own verification work a condition for whether or not it will agree to restart the plant, and the completion of the work is “not foreseeable” (Prefectural Nuclear Safety Division). In light of the inadequacies of the anti-terrorism measures, even a member of the Liberal Democratic Party’s prefectural assembly, which is pro-nuclear power generation, has voiced his desire not to have TEPCO operate the plant, and the sense of distrust is deep-rooted.
 The Japan Atomic Power Company’s Tokai No. 2 Nuclear Power Plant in Ibaraki Prefecture has more than 900,000 people living within a 30-kilometer evacuation zone, the largest in the nation, and the plan has been extremely difficult to formulate. In addition to the prefectural government, only five of the 14 municipalities in the prefecture have been able to formulate a plan. In addition, the Mito District Court ordered an injunction against the operation of the plant last March, citing problems with the effectiveness of the evacuation plan.
 There is almost no chance that both reactors will be able to operate within the government’s target of a little over a year.

More data needed before ocean release of Fukushima water

The full extent of the nuclear isotopes in the damaged plant’s tanks requires more study

There is insufficient information to assess the potential impact that releasing into the ocean contaminated water stored at the Fukushima No. 1 nuclear plant will have on the environment and human health.

by Ken Buesseler, Ferenc Dalnoki-Veress, Antony M. Hooker, Arjun Makhijani and Robert H. Richmond

August 26, 2022

The Nuclear Regulatory Authority last month announced its approval for the discharge of more than 1 million tons of contaminated water from the crippled Fukushima No. 1 nuclear power plant directly into the ocean.

Japan’s nuclear regulator has stated that this can be done safely and the International Atomic Energy Agency has supported this position. We would argue that there is insufficient information to assess potential impacts on environmental and human health and issuing a permit at this time would be premature at best.

Tokyo Electric Power Company Holdings Inc., the plant’s operator, is taking this step as part of the decommissioning and cleanup process of the plant. Every day, more than 150 tons of water accumulates at the site due to groundwater leakage into buildings and the systems used to cool the damaged reactors. The water is currently stored in more than 1,000 tanks at the site and what to do with their ever-increasing number has been a topic of concern for many years.

The justification for ocean discharge focuses largely on the assumed levels of radioactivity from tritium, a radioactive form of hydrogen that cannot be easily removed by an advanced liquid processing system, which is used for treating the contaminated water. To reduce tritium to levels that will be 1/40th of the regulatory standards, dilution of the tank water with seawater has been proposed prior to release. However, tritium is only part of the story, and a full assessment of all of the water contaminants stored in tanks at the site has yet to be made and verified by independent parties.

Our specific concerns include the adequacy, accuracy and reliability of the available data. A key measure of safety is a risk factor that combines the activities of more than 60 radioactive contaminants — the so-called sum of ratios approach. However, only a small subset of these radioactive contaminants — seven to 10 of them, including tritium — have been regularly measured. The assumption is that this subset alone will reflect the possible risks and the other contaminants are at constant levels. We disagree with this approach, as the data show wide variability in the contaminant concentrations between tanks, as well as differences in their relative amounts.

For example, some tanks low in tritium are high in strontium-90 and vice versa. Thus, the assumption that concentrations of the other radionuclides are constant is not correct and a full assessment of all 62 radioisotopes is needed to evaluate the true risk factors.

Moreover, only roughly a quarter of the more than 1,000 tanks at the site have been analyzed. This combined with the large variability among tanks, means that final dilution rates for tritium and the cleanup necessary for all contaminants are not well known. By Tepco’s own estimates, almost 70% of the tanks will need additional cleanup but that estimate is uncertain until all of the tanks are assessed.

The bottom line is that it is impossible to engineer and assess the impact of any release plan without first knowing what is in the tanks. The actual cost and duration of the project, as well as the amount of dilution needed, all depend upon the accuracy and thoroughness of the data. For example, the amount of seawater needed, and hence the time to release, will depend directly upon dilution factors.

Tepco stated in its radiological impact assessment that to meet its requirements, dilution will be needed by a factor “greater than 100.” In fact, the dilution rate we calculate is 250 on average and more than 1,000 times for many of the tanks where analyses are available. Scaling to those higher averages and extremes would increase capacity needs, costs and overall duration of the releases. In addition, comparisons against other possible disposal options — such as vapor release, using enhanced tritium removal technologies, geological burial or the storage option we suggest below — cannot be made without a better assessment of the current tank contents.

Even for tritium, its high levels are not adequately addressed, as it is assumed to be present only in inorganic form as tritiated water. However, there are also organically bound forms of tritium (OBT) that undergo a higher degree of binding to organic material. OBT has been found in the environment at other nuclear sites and is known to be more likely stored in marine sediments or bioaccumulated in marine biota. As such, predictions of the fate of tritium in the ocean need to include OBT as well as the more predictable inorganic form in tritiated water. Tepco has yet to do this.

The focus on tritium also neglects the fact that the nontritium radionuclides are generally of greater health concern as evidenced by their much higher dose coefficient — a measure of the dose, or potential human health impacts associated with a given radioactive element, relative to its measured concentration, or radioactivity level. These more dangerous radioactive contaminants have higher affinities for local accumulation after release in seafloor sediments and marine biota. The old (and incorrect) belief that the “solution to pollution is dilution” fails when identifying exposure pathways that include these other bioaccumulation pathways.

Although statements have been made that all radioactivity levels will meet regulatory requirements and be consistent with accepted practices, the responsible parties have not yet adequately demonstrated that they can bring levels below regulatory thresholds. Rebuilding trust would take cleanup of all of the tanks and then independently verifying that nontritium contaminants have been adequately removed, something the operator has not been able to do over the past 11 years. Post-discharge monitoring will not prevent problems from occurring, but simply identify them when they do occur.

As announced, the release of contaminated material from the Fukushima No. 1 nuclear power plant would take at least 40 years, and decades longer if you include the anticipated accumulation of new water during the process. This would impact not only the interests and reputation of the Japanese fishing community, among others, but also the people and countries of the entire Pacific region. This needs to be considered as a transboundary and transgenerational issue.

Our oceans provide about half of the oxygen we breathe and store almost one-third of the carbon dioxide we emit. They provide food, jobs, energy, global connectivity, cultural connections, exquisite beauty and biodiversity. Thus, any plan for the deliberate release of potentially harmful materials needs to be carefully evaluated and weighed against these important ocean values. This is especially true when contaminated material is being released that would be widely distributed and accumulated by marine organisms.

The Fukushima nuclear power plant disaster is not the first such incident, nor will it be the last. The challenge presented by this present situation is also an opportunity to improve responses and chart a better way forward than to dump the problem into the sea. Moreover, even accepted practices and guidelines require much more thorough preoperational analysis and preparation than is in evidence so far.

We conclude that the present plan does not provide the assurance of safety needed for people’s health or for sound stewardship of the ocean. We have reached this conclusion as members of an expert panel engaged by the Pacific Island Forum, a regional organization comprising 18 countries. However, we have penned this commentary in our individual capacities and our views may or may not be shared by the forum secretariat or its members.

The recent decision to support the release by the Nuclear Regulation Authority is surprising and concerning. In addition, the International Atomic Energy Agency should withhold its support for the release without these issues being resolved. Once the discharge commences, the opportunity to examine total costs and weigh the ocean discharge option against other alternatives will have been lost.

It has been stated that there is an urgency to release this contaminated water because the plant operator is running out of space on site. We disagree on this point as well, as once the tanks are cleaned up as promised, storage in earthquake-safe tanks within and around the Fukushima facility is an attractive alternative. Given tritium’s 12.3-year half-life for radioactive decay, in 40 to 60 years, more than 90% of the tritium will have disappeared and risks significantly reduced.

This is the moment for scientific rigor. An absence of evidence of harm is not evidence that harm will not occur, it simply demonstrates critical gaps in essential knowledge. Having studied the scientific and ecological aspects of the matter, we have concluded that the decision to release the contaminated water should be indefinitely postponed and other options for the tank water revisited until we have more complete data to evaluate the economic, environmental and human health costs of ocean release.

Number of evacuees from Fukushima Prefecture due to the nuclear power plant accident

Mr. Seiichi Nakate (right) handed a written request to the Reconstruction Agency at the House of Representatives building in Chiyoda Ward, Tokyo, on March 23.

August 23, 2022
On August 23, three groups of evacuees from Fukushima Prefecture requested the Reconstruction Agency not to exclude approximately 6,600 people from the number of evacuees from outside of Fukushima Prefecture due to the Fukushima Daiichi Nuclear Power Plant accident, because their whereabouts cannot be confirmed. The reduction in the number of evacuees in the statistics may lead to a trivialization of the damage caused by the nuclear power plant accident.
 The Reconstruction Agency compiles the number of evacuees based on the information that evacuees have reported to the municipalities where they have taken refuge. In some cases, such as when evacuees move away without notifying the local government, their whereabouts are lost. As a result of the survey conducted since last September, approximately 2,900 people’s whereabouts are unknown, and approximately 2,480 people have moved without notifying the municipality. In addition, a total of 6,604 people will be excluded from the evacuee statistics, including approximately 1,110 people who answered “will not return” in the survey.
 As of April, the number of out-of-prefecture evacuees was approximately 23,000, a decrease of more than 3,300 from January, as reports continue to follow this policy. The number is expected to continue to decrease as each municipality works to correct the situation.
 The request was made on this day by the National Association of Evacuees for the “Right to Evacuation” and others. Seiichi Nakate, 61, co-chairman of the association and an evacuee from Fukushima City to Sapporo City, said, “Even though I no longer have the intention to return, I am aware that I am an ‘evacuee. I cannot allow myself to be excluded by the government.” He handed the written request to a Reconstruction Agency official. The official explained that the exclusion would be made in order to match the actual situation of the evacuees, but that it would not affect the support measures.
 At the press conference, Nakate said, “Eleven years have passed since the accident, and the number of official support measures at the evacuation sites is decreasing every year. The evacuee statistics are the basis for all support measures, and I am concerned that they may lead to further reductions in support in the future. (Kenta Onozawa)

The legacy of Shinzo Abe: a Japan divided about nuclear weapons

Japan’s Prime Minister Shinzo Abe announced his resignation due to health concerns on August 28, 2020. Shinzo Abe was assassinated while giving a speech at an election rally on July 8, 2022 in Nara, Japan.

August 24, 2022

On August 1, Prime Minister Fumio Kishida became the first Japanese leader to ever attend the Review Conference for the Treaty on the Non-Proliferation of Nuclear Weapons (NPT), which is taking place this month at UN headquarters in New York. Kishida, whose family hails from Hiroshima, is one of the very few voices within Japan’s ruling party, the Liberal Democratic Party (LDP), to consistently emphasize the humanitarian impacts of the use of nuclear weapons and Japan’s unwavering commitment to nuclear disarmament. This contrasts with his most-recognized predecessor, former Prime Minister Shinzo Abe, whose assassination on July 8, 2022, shocked the entire world.

Abe’s views about nuclear weapons. Shinzo Abe was known to hold views that underscored the effectiveness of nuclear deterrence and the usefulness of nuclear weapons. He even hinted at the possibility that Japan could one day acquire such weapons. During his eight years as prime minister, Abe made Japan’s ambivalent nuclear policy emphasize the importance of the US nuclear umbrella. In doing so, he shifted further away from the brief momentum in favor of nuclear disarmament created by former US President Barack Obama and Abe’s predecessors. From 2012 to 2020, Abe’s second term[1] was marked by heightened tensions and a rapidly deteriorating regional security environment—from China’s aggressive military buildup advancing claims in the East China Sea to North Korea’s increasing nuclear and missile capabilities. In February 2017, during a visit to US President Donald Trump in Washington, Abe successfully obtained reassurance about the unwavering “U.S. commitment to defend Japan through the full range of U.S. military capabilities, both nuclear and conventional.” One year later, in another remarkable sign of Abe’s focus on the role of nuclear weapons, his Foreign Minister Taro Kono issued swift and unequivocal praise of President Trump’s Nuclear Posture Review.

The increasingly tense regional security environment over the past 10 years may certainly have influenced the Abe government’s nuclear views. But Abe’s focus on nuclear weapons started before 2012. Shinzo Abe’s political rhetoric certainly caused several uproars among the Japanese public throughout his political career. But its analysis provides a useful glimpse into his and his party’s nuclear thinking. In one famous example, in May 2002, Shinzo Abe reportedly told students at Waseda University: “The possession of nuclear bombs is constitutional, so long as they are small.”[2] Then Japan’s deputy chief cabinet secretary, Abe was undeterred by the public outcry that followed his remarks and will maintain his views for the rest of his career.

Two decades later, as Russia was invading Ukraine, Shinzo Abe said on television that Japan needs to discuss the option of a NATO-style nuclear-sharing agreement with the United States. This was an apparent revision by Abe of the third principle of Japan’s Three Non-Nuclear Principles, which states Japan shall never permit the introduction of nuclear weapons into its territory. Japan’s Three Non-Nuclear Principles of not possessing, not producing, and not introducing nuclear weapons were established in 1967 by Prime Minister Eisaku Sato, Abe’s great-uncle. Although these principles were never made into law, they are still viewed as the cornerstone of Japan’s official nuclear policy to this day.

In his February 2022 television interview, Abe did try to stand by these principles, saying: “Japan is a party to the Nuclear Non-Proliferation Treaty (NPT) and has the Three Non-Nuclear Principles. As a country that has suffered atomic bombings, it is important to move toward the goal of nuclear abolition.” Still, his remarks about nuclear sharing were harshly criticized by the Hibakusha community—the survivors of the atomic bombings of Hiroshima and Nagasaki in August 1945.

A long political tradition of rhetorical ambivalence. Shinzo Abe’s positive view about the potential value of nuclear weapons for Japan was certainly not unique among Japanese politicians and has been shared by many within the LDP. Several of Abe’s government ministers spoke publicly in favor of the nuclear option or answered that “Japan should consider acquiring nuclear weapons if the international situation calls for it” in surveys by the Mainichi Shimbun, one of Japan’s major newspapers. These included Abe himself, former Deputy Prime Minister Taro Aso, and five former defense ministers. Shinzo Abe’s younger brother and current Defense Minister Nobuo Kishi gave the same response to the Mainichi survey in 2012, although in 2020 he ruled out the nuclear option and publicly supported the Three Non-Nuclear Principles.

Abe’s 2002 assertion about the legality of possessing nuclear weapons under the Japanese Constitution has been made several times by Japanese politicians since the 1950s. For instance, Prime Minister Nobusuke Kishi—Abe’s grandfather—stated in May 1957 during a session of the Diet (Japan’s parliament) that the postwar Constitution did not explicitly forbid Japan from possessing nuclear weapons if they were small. This caused several members of the Diet to interrogate Kishi at the time. Later, during a Diet session in April 1968, a socialist member asked State Minister Kaneshichi Masuda to clarify his position on Japan’s security arrangement with the United States, to which Masuda responded, I translate, “the Constitution, indeed, does not forbid Japan to possess tactical nuclear weapons if they’re solely for self-defense. … Just like the Constitution does not forbid the entry of another country’s nuclear weapons.” But Masuda immediately added that the Three Non-Nuclear Principles are here to cover that loophole.

In March 1973, Prime Minister Kakuei Tanaka also reaffirmed the Three Non-Nuclear Principles. But this time, he added that “while [Japan is] not able to have offensive nuclear weapons, we are not saying that we will have no nuclear weapons at all.” “[S]trategic nuclear weapons are offensive in character and tactical nuclear weapons are defensive,” Tanaka explained, and “defensive nuclear weapons are constitutional.” A similar argument was made by Prime Minister Takeo Fukuda in 1978 during a Diet debate: “[A]rticle 9 of the Constitution does not prohibit the possession of nuclear weapons by Japan. Japan can have them if their purpose is for a minimum level of defense. However, Japan also has the Three Non-Nuclear Principles.”

Shinzo Abe’s position of questioning the limits of Japan’s non-nuclear policy is therefore part of a long political tradition advancing the idea that nuclear weapons might be a possibility for Japan.

Getting rid of Japan’s non-nuclear policy? The long-standing reluctance by Japanese elites to publicly discuss nuclear weapons for Japan, called “the nuclear taboo,” derives from the strong public aversion to such weapons. This aversion was amplified after the Lucky Dragon no. 5 incident on March 1, 1954, when a Japanese fishing boat was contaminated by the nuclear fallout from the US nuclear test at Bikini Atoll. From that day, whenever a Japanese politician even mentioned nuclear weapons, the public reacted very strongly and stayed skeptical of any rhetoric that might suggest the non-nuclear principles and Japan’s status as a Hibakukoku—a country that suffered atomic bombings—not be upheld. Japanese officials and LDP members together have lamented that discussions over a nuclear Japan are still considered taboo. Former Defense Minister Shigeru Ishiba commented in 2017: “How can we take any responsibility if the Three Non-Nuclear Principles are actually four: not possessing, not producing, not introducing, and not even discussing nuclear weapons?” The gap between what the public expects Japanese politicians to say—and not say—and the LDP’s rhetoric about nuclear weapons truly reveals the ambivalence of the country’s official nuclear policy, which has been in place since the end of World War II.

In an ill-timed and bold rhetorical shift, however, Abe omitted the usual pledge to uphold the Three Non-Nuclear Principles in his Hiroshima speech on August 6, 2015. The omission, during the official ceremony commemorating the 70th anniversary of the atomic bombings, caused great anxiety among many and prompted angered responses from the Hibakusha community. Anti-nuclear activist and Hibakusha Tomoyuki Mimaki noted: “It seems like the government is disrespecting the Three Non-Nuclear Principles.” Another activist, Kazuo Okoshi, commented: “Some politicians advocate for nuclearization. This is proof that the Three Non-Nuclear Principles are weakening.” Probably in response to the public outcry following his omission, Abe did mention the Three Non-Nuclear Principles in his speech in Nagasaki three days later. In doing so, Abe was reassuring the Japanese that there would be no change to the official nuclear policy.

This long history of mixed messages and rhetorical mishaps by leaders of Japan’s ruling party can be read as the inevitable consequence of the country’s ambiguous nuclear policy, swinging between effective nuclear deterrence and global nuclear disarmament aspirations. But this posture can be also understood as creating a hedging strategy about nuclear weapons perceived as necessary by many within the LDP. Politicians of the ruling party may indeed have seen it as advantageous for Japan to flash the “nuclear card” from time to time while still referring to the Three Non-Nuclear Principles.

Talking to different audiences. The ambivalent nature of Japan’s nuclear policy may appear useful in catering to different audiences at home and abroad. The first and most obvious audience intended to receive signaling about the nuclear card consists of Japan’s regional adversaries, especially China. Statements about the constitutional right to possess nuclear weapons exemplify such rhetoric and are partly aimed at keeping Japan’s adversaries uncertain about their neighbor’s ultimate security intentions. As former Executive Director of the International Energy Agency Nobuo Tanaka wrote in 2018: “[G]iven recent geopolitical developments in Northeast Asia, eliminating Japan’s nuclear capability could be very unwise. If so, whether and how we should maintain Japan’s nuclear capability needs to include the national security perspective as part of a serious public discussion. Japan will never ever build nuclear weapons, and yet being suspected of doing so by some of its neighbors, is probably the strongest national security reason for Japan to continue to use nuclear power.”

The second audience is domestic. Japan is widely viewed as a nuclear threshold state, as it has significant latent capabilities due to its highly advanced nuclear fuel cycle technologies. That Japan refuses to develop nuclear weapons despite its latent nuclear status has been used by Japanese officials to reassure the public about the security of the archipelago, while keeping its moral stance vis-à-vis global peace. Possessing latent nuclear capabilities yet not going nuclear is indeed considered proof that Japan is an international role model and fits in the official narrative that Japan is a bridge-builder between nuclear and non-nuclear states. At the same time, because this rhetoric is ambiguous, it also provides Japanese leaders with another way to remind the public of the country’s potential to go nuclear, if it decides to.

The first recorded instance of such reassurance discourse dates from 1958. In his memoirs published in 1983, Prime Minister Nobusuke Kishi wrote after a visit to the new Tokai-mura nuclear facility “Japan does not have nuclear weapons, but by showing that we possess the technology to build them, we can increase our political leverage at the international level when it comes to disarmament issues and nuclear testing.”

A more explicit version of this argument features in a Diet debate in October 2006, when Akira Amari, minister of economy, trade, and industry under Shinzo Abe’s first premiership, stated, I translate: “Japan has the capabilities [to go nuclear], but doesn’t. The fact that Japan declares that it has no intention of doing so while maintaining those capabilities is what truly makes Japan’s policy convincing. If a country that doesn’t have the capabilities to go nuclear declares that it will not go nuclear, it is just lip service. However, Japan does have the technical capabilities, yet it asserts that it will not go nuclear: this is exactly what makes Japan a credible and persuasive advocate for the abolition of nuclear weapons around the world.” In other words, retaining nuclear latency adds credibility to disarmament matters.

The third audience is the United States, with which Abe has been particularly keen to engage. On some occasions, nuclear statements made by Japanese officials have alluded to a “nuclear option.” These were directed to the United States and meant to test its commitment to defend Japan. Commenting on North Korea’s nuclear test and ballistic missile launch of early 2016, Abe stated, in presence of US Pacific Commander Admiral Harry Harris, that “[t]he missile launch by North Korea was not only a direct threat to Japan but also a challenge to the United States.” Japanese political scientist Shogo Imoto commented at the time: “It is clearly an exaggeration to state that Mr. Abe is thinking of nuclear weapons for Japan. However, I interpret [his quote] as the following: ‘If the United States abandons Japan now and runs away from the North Korean threat, Japan will seriously consider a shift in its policy and nuclearize. Japan wants the United States to be fully aware of this as you tackle the North Korean issue.’”

These messages have appeared each time Japan felt its regional environment was becoming more challenging, as happened in December 1964 when Japan’s Prime Minister Eisaku Sato reportedly told US ambassador Edwin Reischauer that Japan could develop nuclear weapons. Sato’s remarks were made after China had conducted its first successful nuclear bomb test in October 1964.

The fourth and last audience is the most conservative part of the Japanese public. Using the slogan “Take Japan back” (Nippon wo torimodosu), Abe’s campaign for a second term appeared to go beyond the mainstream conservatism of LDP politicians and revealed the prime minister’s overtly nationalistic values and agenda. When Abe rose to power for the second time in 2012, many Japanese and international analysts warned about his revisionist and nationalist views and the regional instability they could cause. Some analysts even labeled Abe as “the most conservative leader in Japan’s postwar history.” Abe, however, quickly managed to eclipse his nationalist label by skillfully handling newly elected US President Donald Trump and even enjoyed a new reputation as a proactive diplomat seeking engagement and mediation. But in the nuclear rhetoric of Shinzo Abe, as of his closest allies, one could still find hints and allusions to nuclear weapons’ prestige and relevance to international politics.

Abe’s nuclear legacy. The deeply ambivalent messages that paved Abe’s political career point to the perception by LDP leaders that a nuclear stance needs to simultaneously address all four audiences—adversaries, allies, the Japanese public, as well as its most conservative fraction. But Shinzo Abe’s views on nuclear weapons do not only reflect the longstanding strategy of his party. His continued, strong emphasis on the need for nuclear deterrence also resulted in a sharper divide and a greater hostility between the government and largely anti-nuclear public opinion in Japan. Moreover, even though Abe’s views were not at odds with the LDP, his government’s reliance on nuclear deterrence uniquely contributed to consolidating Japan’s nuclear hedging posture even further. The delays and hesitation by Abe’s government in presenting a clear roadmap for the management of the country’s plutonium stockpile as well as its nuclear energy policy also exacerbated the distrust of the public, still embittered by how the government managed the aftermath of the 2011 Fukushima nuclear disaster.

Japan’s current prime minister, Fumio Kishida, is now highlighting Japan’s goal of nuclear disarmament and publicly rejected Abe’s idea of nuclear sharing. But the country’s nuclear hedging posture is so entrenched in the political thinking of the LDP’s leadership that it is highly unlikely Japan’s ambivalent nuclear policy will change in the foreseeable future.

Kishida’s speech on August 1 at the United Nations on the first day of the NPT Review Conference already drew harsh criticism from the Hibakusha community for failing to mention the Treaty on the Prohibition of Nuclear Weapons (TPNW, also called the “ban treaty”) and for not clarifying Japan’s future role in nuclear disarmament. Kishida’s efforts to re-center the country’s nuclear policy towards disarmament may be sincere, but it will have to overcome the wide gap between the public and the government that Abe’s focus on nuclear deterrence further exacerbated.

Through his security-oriented nuclear views, Shinzo Abe attempted to diminish the Japanese public’s long-standing allergy to and the country’s emotional wounds over nuclear weapons. However, his nuclear legacy has created an even wider divide in Japan—between those who think of nuclear policy exclusively in terms of disarmament and those who prefer emphasizing Japan’s deterrence needs. How Abe’s nuclear legacy will impact the future of nuclear policy in Japan—in one direction or another—is an open question.

Notes

[1] Shinzo Abe served four terms as prime minister of Japan, in 2006–2007, 2012–2014, 2014–2017, and 2017–2020. His last three contiguous terms from 2012 to 2020 are often referred to as his “second term.” Abe has been the longest-serving prime minister in Japan to date.

[2] What Shinzo Abe is reported to have said is not entirely clear. Some news outlets report that he said: “There is no problem with atomic bombs, constitutionally speaking. As long as they’re small.” (Wall Street Journal Japanese version) Others state he said: “The possession or use of nuclear weapons is not a problem constitutionally, as long as they’re small” (Sunday Mainichi magazine). As this was an oral remark at an event at Waseda University, it is difficult to know what Abe said exactly. In any case, his remarks were later criticized very harshly by the Japanese public.
