The News That Matters about the Nuclear Industry Fukushima Chernobyl Mayak Three Mile Island Atomic Testing Radiation Isotope

Hiroshima atomic bomb survivor, who taught others about opposing nuclear weapons, dies at 96.


Hiroshima atomic bomb survivor, who taught others about opposing nuclear weapons, dies at 96, Fox News, 

Sunao Tsuboi was 20 years old when he survived atomic bombing Sunao Tsuboi, a survivor of the Hiroshima atomic bombing who made opposing nuclear weapons the message of his life, including in a meeting with President Obama in 2016, has died. He was 96. 

Tsuboi died Oct. 24 in a hospital in Hiroshima in southwestern Japan. The cause of death was given as an irregular heartbeat caused by anemia, Nihon Hidankyo, the nationwide group of atomic bomb survivors he headed until his death, said Wednesday. 

When Obama made his historic visit to Hiroshima, Obama and Tsuboi held each other’s hand in a long handshake and shared a laugh. An interpreter stood by. Tsuboi, a gentle yet passionate man, recalled he tried to talk fast, to tell Obama he will be remembered for having listened to atomic bomb survivors, known in Japanese as “hibakusha.” …………..

“Here it was about annihilation,” he told the AP. 

Tsuboi worked as a junior high school teacher. He was so intent on educating youngsters about anti-nuclear proliferation his nickname became “pikadon sensei,” combining the “flash-boom” onomatopoeia Japanese use to describe the bomb and the word for “teacher.” 

“Never give up” was his trademark phrase, especially for his fight for a world without nuclear weapons. 

Akira Kawasaki of ICAN, or the International Campaign to Abolish Nuclear Weapons, a coalition of non-government organizations, said the death of a man who had been the poster boy for anti-nuclear proliferation left him with a “big hole” in his heart. 

We must not only mourn the death of a great leader for our cause, but we must also continue in his path, undeterred, and always remember his words,” he told Japanese public broadcaster NHK TV. …….. https://www.foxnews.com/world/hiroshima-atomic-bomb-survivor-dies-96

Pumice may affect nuclear power plants in Japan

Pumice may affect nuclear power plants in Japan, https://www3.nhk.or.jp/nhkworld/en/news/20211027_36/      Japan’s nuclear regulator says a massive number of pumice stones drifting in waters in the country’s southwest could affect domestic nuclear power plants.

Ishiwatari Akira, a member of the Nuclear Regulation Authority, told a regular meeting on Wednesday that the stones may affect the intake of water used for cooling nuclear reactors.

The pumice stones are being washed ashore on the coast of Okinawa Prefecture and the Amami region of Kagoshima Prefecture. They come from an undersea volcanic eruption near the Ogasawara island chain in the Pacific Ocean in August.

Japanese government’s energy policy concentrates on restarting old nuclear reactors

Japan remains focused on restarting nuclear reactors,  Argus,  25 Oct 21, Japan will continue to focus on restarting nuclear reactors instead of building new reactors….Japanese premier Fumio Kishida and cabinet ministers on 22 October endorsed a basic energy policy that did not lay out any plans for construction or replacement of nuclear reactors and only focused on the restart of safe reactors. ………..6Under the latest energy policy, Japan plans to generate 20-22pc of power ou  icy B1lop paJcOput from nuclear energy, with 36-38pc from renewables, 41pc thermal power and 1pc from hydrogen and ammonia in 2030-31, which were also unchanged from the draft plans…………………….

Japan will phase out nuclear reactors without any capacity additions. Under the current nuclear safety rules, all reactors are allowed to operate for 40 years with a one-time option to extend their lifespan to 60 years. This suggests that 15 of the existing 33 reactors with a combined capacity of 14,057MW will close by December 2030 and there will be no operational reactors in 2050, assuming a 40-year lifespan.
The future of the nuclear industry also depends on which political party will take majority seats in the 31 October lower house parliamentary election, as most parties have pledged a no-nuclear society. The current ruling liberal democratic party of Japan promotes the restart of safe reactors, without directly prohibiting building reactors. But the second largest the constitutional democratic party has pledged not to allow any new building of reactors in its manifesto.

Recently restarted – Fukui nuclear unit halted for a year on safety issues.

Fukui nuclear unit halted after missing deadline on antiterror steps  https://english.kyodonews.net/news/2021/10/e69ddb77abbd-fukui-nuclear-unit-halted-after-missing-deadline-on-antiterror-steps.html

 KYODO NEWS – Oct 23, 2021 –  A nuclear reactor in central Japan’s Fukui Prefecture was halted on Saturday, just four months after its restart as it could not meet a deadline set by regulators to implement antiterrorism measures.

The suspension of Kansai Electric Power Co.’s Mihama No. 3 unit came ahead of the deadline on Monday for such measures to be completed. After undergoing safety checks, the utility aims to make the necessary changes to its facilities around September next year and restart operations in mid-October.

In June, the No. 3 unit went online for the first time in about 10 years and became the first nuclear unit to operate beyond the government-mandated 40-year service period introduced under new rules set after the 2011 Fukushima disaster.

The reactor had stopped operations after the crisis at the Fukushima Daiichi plant triggered by a massive earthquake and tsunami. Regulators gave the green light to the aging No. 3 unit after screening the utility’s safety measures.

The Nos. 1 and 2 units of the Mihama plant were terminated in April 2015 in line with the 40-year limit.

Backlash against Japanese Prime Minister’s haste to dump Fukushima nuclear water into the ocean


Kishida triggers backlash by saying dumping Fukushima nuclear water can’t be delayed, Global Times, By Xu Keyue: O
ct 19, 2021   Only two weeks after taking office, Japan’s new prime minister Fumio Kishida pressed two hot buttons on the same day on Sunday – sending a ritual offering to the war-linked Yasukuni Shrine, and claiming the Fukushima wastewater release cannot be delayed, despite opposition from home and abroad.


Instead of taking full advantage of its own science and technology to process the Fukushima wastewater and deliver a qualified answer to the world over the water treatment, Japan has opted for its irresponsible plan to dump the wastewater as soon as possible and provided self-contradictory explanations for the decision, said Chinese experts.Speaking at his first visit to the tsunami-wrecked Fukushima nuclear plant since taking office, Kishida said the planned mass disposal of wastewater stored at the facility cannot be delayed, claiming his government would work to reassure residents nearby the plant about the technical safety of the wastewater disposal project, Asahi Shimbun reported Monday.

South Korea has expressed concern over Kishida’s plan to release the radioactive wastewater, according to South Korean media on Monday.

“Japan’s decision [to discharge the wastewater] was made without enough consultations with neighboring nations,” a senior South Korean foreign ministry official said. “We have expressed serious concerns and opposition to its plan, which could affect our people’s health and security as well as the ocean environment.”

The Tokyo Electric Power Company Holdings Inc. (TEPCO) has planned to build a one-kilometer undersea tunnel to release contaminated radioactive water out to sea, amid condemnation from fishermen, media reported in late August.

The plan again showed that Japan’s “explanation” over the safety of the water is “self-contradicting,” Liu Jiangyong, vice dean of the Institute of Modern International Relations at Tsinghua University, told the Global Times on Monday.
Assuming the wastewater has been processed without any side effects or pollution as the Japanese government claimed, and that people can even drink it, why does the Japanese government not simply discharge the water into the sea but plan to dump the water 1 kilometer away from the local residents? asked Liu. He also questioned the claim that it will have no impact on the marine environment and life chain, and asked why the water could not be recycled on land if the wastewater can be processed so cleanly and safely.

Japan can’t answer any of these questions, said Liu, noting that dumping the nuclear water shows that the water is “unusual.”…………. https://mail.google.com/mail/u/0/?tab=rm&ogbl#inbox?compose=DmwnWsTJtkLTcgrqMkBKSqBpmgbKhMHpzMMgttqhvJHgDJrfsKrtFCCwkflZJkjjhwgvJbPrQhFV

Prime Minister Fumio Kishida confirms release of Fukushima wastewater to start in 2023


Release of Fukushima wastewater to proceed: Kishida, The Guardian, TOKYO, 18 Oct 21,

New Japanese Prime Minister Fumio Kishida has said that there can be no delay to plans to release contaminated water from the wrecked Fukushima Dai-ichi nuclear power plant into the sea, despite opposition from fishers and neighboring countries.

Kishida, who made his first trip to the plant on Sunday since becoming prime minister last month, said every effort would be made to reassure local people that disposing of the water in the Pacific Ocean was safe……

Researchers have used snakes fitted with tracking devices and dosimeters to measure radiation levels in the area around the Fukushima Dai-ichi Nuclear Power Plant, which suffered triple meltdowns in March 2011……

More than 1 million tonnes of water are being stored in 1,000 tanks at the site, and TEPCO has said that space would run out late next year.

The government and TEPCO in April said that work to release the heavily diluted water would begin in the spring of 2023 and take decades to complete.

The move is opposed by nearby fishing communities, which say it would undo years of hard work rebuilding their industry’s reputation since the plant was struck by a huge tsunami in March 2011, soon after Japan’s northeast coast was rocked by a magnitude 9 earthquake.

The decision ended years of debate over what to do with the water, with other options including evaporation or the construction of more storage tanks at other sites.   More than 1 million tonnes of water are being stored in 1,000 tanks at the site, and TEPCO has said that space would run out late next year.

Japan’s new pro nuclear push – and for small nuclear reactors

Japan’s Carbon Goal Is Based on Restarting 30 Nuclear Reactors, Bloomberg,  By Isabel Reynolds 17 October 2021,  Japan’s goal of reducing carbon emissions by 46% by 2030 is based on the assumption it will restart 30 of its nuclear reactors, a top ruling party executive said. 

Akira Amari, secretary general of the Liberal Democratic Party, made the remarks Sunday in a televised debate broadcast by NHK ahead of the Oct. 31 general election. 

Much of Japan’s nuclear capacity has been offline since the 2011 Fukushima disaster and Amari said only nine reactors are currently in service. Surveys generally show the electorate is against restarting the plants. 

The LDP has also been promoting the idea of building small modular reactors, saying they are safer than Japan’s existing atomic plants……..https://www.bloomberg.com/news/articles/2021-10-17/amari-says-japan-s-carbon-goal-based-on-restarting-30-reactors

Lethal radiation levels detected in Fukushima nuclear plant reactor lid 

Lethal radiation levels detected in Fukushima nuke plant reactor lid   https://www.asahi.com/ajw/articles/14440765

By TSUYOSHI KAWAMURA/ Staff Writer

September 15, 2021  
The operator of the crippled Fukushima No. 1 nuclear plant could be forced to reconsider the plant’s decommissioning process after lethal radiation levels equivalent to those of melted nuclear fuel were detected near one of the lids covering a reactor.

The Nuclear Regulation Authority said Sept. 14 that a radiation reading near the surface of the lid of the No. 2 reactor’s containment vessel was 1.2 sieverts per hour, higher than the level previously assumed.

The discovery came on Sept. 9 during a study by the NRA and Tokyo Electric Power Co., the operator of the plant.

TEPCO plans to insert a robotic arm into the No. 2 reactor’s containment vessel from its side in a trial planned for the second half of 2022 to retrieve pieces of melted nuclear fuel.

“We will consider what we can do during the trial on the basis of the detection of the concentration of contamination” in the upper area of the containment vessel, a TEPCO official said.

The round concrete lid, called the shield plug, is 12 meters in diameter and about 60 centimeters thick.

The shield plug consists of three lids placed on top of each other to block extremely high radiation emanating from the reactor core.

Each lid weighs 150 tons.

When operators work on the decommissioning, the shield plug will be removed to allow for the entry into the containment vessel.

The NRA said a huge amount of radioactive cesium that was released during the meltdown of the No. 2 reactor in March 2011 remained between the uppermost lid and middle lid.

In the Sept. 9 study, workers bored two holes measuring 7 cm deep each on the surface of the uppermost lid to measure radiation doses there by deploying remotely controlled robots.

One radiation reading was 1.2 sieverts per hour at a location 4 cm down from the surface in a hole near the center of the lid.Prior to the study, the NRA estimated that the dose from a contamination source that existed beneath the lid was more than 10 sieverts per hour, a level lethal to humans if exposed to it for about an hour.

But the finding suggested that the actual dose would likely be dozens of sieverts per hour, thus far more dangerous.

While it is expected to be a huge challenge to dismantle the lids, TEPCO has yet to decide what to do with them during the decades-long cleanup work.

The NRA also mentioned the possibility that radioactive cesium is also concentrated between the middle lid and the lowermost lid.

But there is no way at the moment to confirm whether that is the case, according to NRA officials

Nuclear hawks under Kishida threaten Suga’s renewables push

THE ASAHI SHIMBUN, October 14, 2021 Pro-nuclear lawmakers now hold key positions under Prime Minister Fumio Kishida, sparking concern that he will stray from the prior administration’s focus on renewables to help achieve “net zero” greenhouse gas emissions by 2050.

New ministers in charge of Japan’s efforts to fight climate change and energy issues under the Kishida administration have vowed to stick with the net zero target………

The new Basic Energy Plan drafted by the Suga administration made no mention of such nuclear power-related projects despite pressure from pro-nuclear lawmakers within the LDP and the nuclear industry.

LDP lawmakers who support nuclear energy are unhappy about the Basic Energy Plan, which said Japan will “reduce its dependence on nuclear energy as much as possible.”   

……………concerns have been raised over a possible return to reliance on more nuclear power following pro-nuclear lawmakers assuming key posts in the government and the ruling Liberal Democratic Party.

Koizumi, who as environment minister pushed for renewable energy, and Taro Kono, who served as minister in charge of administrative reform and is a staunch opponent of nuclear energy, were replaced when Kishida formed his Cabinet.

….. Despite his vow against new reactor projects, Hagiuda is a close ally of former Prime Minister Shinzo Abe, who serves as the most senior adviser to a group of lawmakers advocating construction of new reactors to replace aged units.

Akira Amari, the new secretary-general of the LDP, the second most powerful post after the party president, Kishida, is the most senior adviser to the group.

Sanae Takaichi, who proposed bolstering development of new technology to build a nuclear fusion reactor during the LDP

 leadership race last month, landed the position of the party’s policy chief.

…Not surprisingly, the nuclear industry hailed the government and the new party lineup…….. https://www.asahi.com/ajw/articles/14460623

Japanese Prime Minister Fumio Kishida praises Treaty on the Prohibition of Nuclear Weapons

ICAN 9 Oct 21, After receiving a letter from Hiroshima survivor and long-time ICAN activist Setsuko Thurlow and ICAN, the new Japanese Prime Minister Fumio Kishida said “I believe that the Treaty on the Prohibition of Nuclear Weapons is a very important treaty for a world without nuclear weapons.” This is definitely a good sign from a nuclear allied country that previously has dismissed our treaty.  


Setsuko had already met with Mr Kishida in 2018, together with ICAN partner Peace Boat, to discuss Japan’s nuclear disarmament policy and we will use the opportunity of this new Prime Minister to strengthen our work to get Japan join the treaty.

Japan’s independent English language newsletter, analysing nuclear issues, is struggling to survive

Japan NPO on nuke power issues struggling to retain English newsletter

September 27, 2021 (Mainichi Japan    TOKYO (Kyodo) — A citizens’ organization in Japan that publishes independent analysis in English on nuclear power issues is struggling financially, threatening its ability to remain the major source of specialized public information on Japan’s nuclear industry for an international audience.

The Citizens’ Nuclear Information Center based in Tokyo has published the free bimonthly English newsletter Nuke Info Tokyo since 1987 but is having to crowdfund to keep publishing amid financial difficulties caused by the coronavirus pandemic.

The nonprofit organization, which also produces a monthly newsletter in Japanese for a domestic audience, had previously financed the cost of the English publication by holding paid seminars at which it also solicited donations and sold books, as well as collecting membership fees.

But it has been unable to hold the events since early 2020 when coronavirus infections began to impact Japan, Hajime Matsukubo, CNIC secretary general, told Kyodo News.

Membership — already in decline — has also dropped further amid the pandemic and its effect on the economy, he said.

“Membership decreased by about 100 last year alone under the coronavirus outbreaks and (membership) is around 2,100 now,” Matsukubo said, admitting the decline in membership also owed to a waning of public interest in nuclear issues in recent years.

…………. Philip White, a former editor of Nuke Info Tokyo, wrote that he fielded calls around the clock from the foreign media by referring to the archived English-language articles at the time of the disaster.

“The international media was hungry for critical information to counter the sanitized version offered by the government and the nuclear industry. Our English website offered clearly referenced Nuke Info Tokyo articles,” he wrote……………

Matsukubo argues that the government and electric power companies operating nuclear plants tend to withhold information, not just when accidents occur but also in normal times.

Although the government has said the Fukushima plant is under control, it is uncertain how many more years it will take to deal with over a million tons of treated radioactive water from the plant and decommission damaged reactors.

The government continues to deem nuclear power a major energy source, although, since 2014, it has said it aims to decrease its reliance on such power.

Running the English newsletter, staffed by Stronell, four freelance translators, and an editor who is also co-director of the group, costs around 1.5 million yen ($13,700) per year. While the translators used to work voluntarily, CNIC started to pay them in 2009 — though they receive half or less than the market rate.

At this time, the newsletter, which had been printed and mailed to readers with a postage fee charged only to readers in Japan, was made available for free online. Several hundred readers regularly refer to the newsletter, among them journalists, NGO staff, and academics.

Another co-director of CNIC, Hideyuki Ban, said that researchers worldwide have quoted Nuke Info Tokyo in their work.

“Nuke Info Tokyo is the only newsletter in English that specializes in the situation of nuclear power in Japan and has covered a wide range of issues from citizens’ standpoints for decades,” Ban said.

CNIC was founded in 1975 by scientists, including the late Jinzaburo Takagi, a nuclear chemist who began his career in the nuclear industry but later voiced concerns about atomic power……..

To coincide with the policy discussion, CNIC held a virtual seminar on Friday to draw attention to the issues and help people make up their minds on the right policy for Japan.

Stronell said she hopes to run an article on the seminar given by experts in the newsletter.

“I think the most important thing is having independent experts’ information on nuclear power accidents like Fukushima and other problems to let people make decisions about their own health and future,” Stronell said. “And so for us to continue to do this, and that’s what the crowdfunding project is about, any support is very much appreciated.” https://mainichi.jp/english/articles/20210927/p2g/00m/0na/078000c

Nuclear submarine for Japan? Kono says yes, Kishida says no

Poll leader believes capability is ‘extremely important’ for country

Navy divers assigned to Naval Special Warfare Command conduct operations with the nuclear-powered fast-attack submarine USS North Carolina off the coast of Oahu, Hawaii.

September 26, 2021

TOKYO — Following a recent deal by the U.S. and the U.K. to offer Australia classified technology to build nuclear-powered submarines, should fellow Quad member Japan also seek such a capability? The four candidates running for the Liberal Democratic Party presidential race to succeed Prime Minister Yoshihide Suga were asked the question Sunday on Fuji TV.

Poll leader Taro Kono, minister for administrative reform and also in charge of vaccine distribution, gave a thumbs-up. “As a capability, it is very important for Japan to have nuclear submarines,” he said.

“Whether there are regions [in Japan] willing to host them as a home port, or whether the operating capabilities or costs are pragmatic, these are issues we need to consider going forward,” he added. 

Sanae Takaichi, the former internal affairs minister, also looked favorably upon the idea. “If we think of the worst-case risks in the international environment ahead, I do believe we could have [submarines] that can travel a little longer,” she said, referring to the advantage of nuclear propulsion in that they can stay submerged longer without refueling.

Japan’s Atomic Energy Basic Law stipulates that the use of nuclear power will be limited to peaceful purposes. Takaichi said there was “a need to sort things out” but added she did not believe nuclear-powered submarines to be unconstitutional. 

Former LDP policy chief Fumio Kishida, meanwhile, was less receptive to the idea. “When I think about Japan’s national security arrangements, to what extent do we need it?” he asked.

Nuclear-powered submarines are faster and can travel longer compared to the diesel-electric submarines that Japan currently has. But Kishida was alluding to the fact that the Self-Defense Forces’ operations are primarily in areas close to Japan.  

“To maintain stealth, it will require long hours of work,” he said. “We have to prioritize improving working conditions [of sailors] and secure the personnel.”

Japan’s Maritime Self-Defense Force has struggled to hire sailors in a country whose population is declining. Submarines are especially unpopular among young recruits, partly because they are unable to use their smartphones for extended periods.

Seiko Noda, the LDP’s executive acting secretary-general, said: “I have no intention to hold such a capability. I want to make clear that we are a nation with three non-nuclear principles,” she said, pointing to Japan’s long-held position of neither possessing nor manufacturing nuclear weapons, nor permitting their introduction into Japanese territory.

“This is not a situation where we can immediately buy and start to use the submarines,” she said. “We must properly establish a national consensus.” 

On Sept. 16,  the U.S., the U.K. and Australia announced an enhanced trilateral security partnership called AUKUS, that will see Washington and London share sensitive nuclear-propulsion technology with Canberra to develop a fleet of nuclear-powered submarines. It is a move to bolster deterrence against China’s growing maritime power.

Japan’s election campaign – Liberal Democratic Party candidates’ differing views on nuclear recycling.

Three of the four candidates vying to lead the Liberal Democratic Party
called Sunday for Japan to maintain its nuclear fuel recycling program as
they geared up for the last few days of campaigning prior to Wednesday’s
vote. During a Fuji TV program, vaccination minister Taro Kono, the only
contender who has pushed for phasing out nuclear power generation, went
against his leadership rivals and said Japan should pivot away from fuel
recycling “as soon as possible.”

Will Fukushima’s Water Dump Set a Risky Precedent?

Will Fukushima’s Water Dump Set a Risky Precedent? IEEE Spectrum 
Questions raised over new norms the disaster’s radioactive wastewater cleanup efforts may foster
, RAHUL RAO 24 SEP 2021   Since the Japanese earthquake and tsunami in March 2011, groundwater has been trickling through the damaged facilities at the Fukushima Daiichi nuclear power plant, filtering through the melted cores and fuel rods and becoming irradiated with a whole medley of radioisotopes. Japanese authorities have been pumping that water into a vast array of tanks on-site: currently over a thousand tanks, and adding around one new tank per week.

Now, Japanese authorities are preparing to release that water into the Pacific Ocean. Even though they’re treating and diluting the water first, the plan is meeting with vocal protests. From that opposition and from scientists’ critiques of the process, the ongoing events at Fukushima leave an unprecedented example that other nuclear power facilities can watch and learn from.

The release is slated to start in 2023, and potentially last for decades. This month, observers from the International Atomic Energy Agency have arrived in the country to inspect the process. And efforts are also underway to build an undersea tunnel that will discharge the water a kilometer away from the shore.

Before they do that, they’ll treat the water to cleanse it of radioactive contaminants. According to the authorities’ account of the situation, there’s one major contaminant that their system cannot cleanse: tritium.

It’s actually normal for nuclear power plants to release tritium into the air and water in their normal operations. In fact, pre-disaster, Fukushima Daiichi held boiling-water reactors, the lowest-tritium type of nuclear reactors. The Japanese government’s solution is to dilute the tritium-contaminated water down to comparable levels. That’s part of the reason the discharge will likely last several decades.

“While one can argue whether such release limits are appropriate in general for normally operating facilities, the planned release, if carried out correctly, does not appear to be outside of the norm,” says Edwin Lyman, director of nuclear power safety at the Union of Concerned Scientists.

Even so, the plan has—perhaps expectedly—encountered some rather vocal opposition. Some of the loudest cries have come from within Japan, particularly from the fishing industry. Radiation levels in seafood from that coast are well within safety limits, but fishing cooperatives are concerned the plan is (once again) putting their reputations at stake………….

can the events at Fukushima offer other energy facilities around the world any lessons at all?

For one, they’re a good show of the need for emergency planning. “Every nuclear plant should be required to analyze the potential for such long-term consequences,” says Lyman. “New nuclear plants, if built, should incorporate such evaluations into their siting decisions.”

But there’s other things experts say that facilities could learn. For example, something that hasn’t always been present in the Fukushima matter—working against it—has been transparency.

Authorities at the plant haven’t fully addressed the matter of non-tritium contaminants, according to Ken Buesseler, a marine radiochemist at Woods Hole Oceanographic Institution who has studied radioactivity in the ocean off Fukushima. Some contaminants—like caesium-137 and strontium-90—were present in the initial disaster in 2011. Others—like cobalt-60 and cerium-144—entered the water later.


It isn’t something the authorities have completely ignored. “Japan plans to run the water again through the decontamination process before release, and the dilution will further reduce the concentrations of the remaining isotopes,” says Lyman.

But Buesseler isn’t convinced that it will be enough. “Theoretically, it’s possible to improve the situation a lot,” he says. “In practice, they haven’t done that.” Japanese authorities insist they can do so, but their ability, he says, hasn’t been independently verified and peer-reviewed……….

“I’d hate to see every country that has radioactive waste start dumping waste into the ocean,” he says. “It’s a transboundary issue, in a way. It’s something bigger than Japan, and something different from regular operation. I think they need to be at least open about that, getting international approval.”

Here, Lyman agrees. “This situation is unique and the decision to release the water into the sea should not set a precedent for any other project.”

But even taking all of that into account, some believe that, if anything, this is an example of a time when there simply is no choice but to take drastic action.

“I believe that this action is necessary to avoid potentially worse consequences,” says Lyman. https://spectrum.ieee.org/fukushima-wastewater-cleanup-questions
