Nuclear energy cannot lead the global energy transition

With nuclear energy, when things go wrong, they go very, very wrong

Masayoshi Iyoda, Campaigner in Japan for 350.org, 3 Apr 24, ore https://www.aljazeera.com/opinions/2024/4/3/nuclear-energy-cannot-lead-the-global-energy-transition

On March 11, 2011, a magnitude 9 earthquake and a subsequent 15-metre tsunami struck Japan, which triggered a nuclear disaster at TEPCO’s Fukushima Daiichi nuclear plant. Three of the six plant’s reactors were affected, resulting in meltdowns and the release of a significant amount of radioactive material into the environment.

Today, 13 years later, Japan is still experiencing the impacts of this disaster. Immediately after the earthquake struck, more than 160,000 people were evacuated. Of them, nearly 29,000 still remain displaced.

Disastrous health effects due to exposure to radioactivity are still a serious concern for many, and environmental impacts on land, water, agriculture, and fisheries are still visible. The cost of the damage, including victim compensation, has been astronomical; $7bn has been spent annually since 2011, and work continues.

Last year, Japan’s plan to start releasing more than a million tonnes of treated wastewater into the Pacific Ocean sparked anxiety and anger, including among community members who rely on fishing for their livelihoods, from Fukushima to Fiji.

Yet, Japan and the rest of the world appear not to have learned much from this devastating experience. On March 21, Belgium hosted the first Nuclear Energy Summit attended by high-level officials from across the globe, including Japanese Vice-Minister for Foreign Affairs Masahiro Komura. The event was meant to promote the development, expansion and funding of nuclear energy research and projects.

The summit came after more than 20 countries, including Japan, announced plans to triple nuclear energy capacity by 2050 at last year’s UN Climate Change Conference (COP28).

All of these developments go against growing evidence that nuclear energy is not an efficient and safe option for the energy transition away from fossil fuels.

Despite advancements in waste-storage technology, no foolproof method for handling nuclear waste has been devised and implemented yet. As nuclear power plants continue to create radioactive waste, the potential for leakage, accidents, and diversion to nuclear weapons still presents significant environmental, public health, and security risks.

Nuclear power is also the slowest low-carbon energy to deploy, is very costly and has the least impact in the short, medium and long term on decarbonising the energy mix. The latest Intergovernmental Panel on Climate Change (IPCC) report pointed out that nuclear energy’s potential and cost-effectiveness of emission reduction by 2030 was much smaller than that of solar and wind energy.

Large-scale energy technologies like nuclear power plants also require billions of dollars upfront, and take a decade to build due to stricter safety regulations. Even the deployment of small modular reactors (SMR) has a high price tag. Late last year, a flagship project by NuScale funded by the US government to the tune of hundreds of millions of dollars had to be abandoned due to rising costs.

In addition to that, according to a report released by Greenpeace in 2023, even in the most favourable scenario and with an equal investment amount, by 2050, the installation of a wind and solar power infrastructure would produce three times more cumulative electricity and emit four times less cumulative CO2 compared to a water nuclear reactor in the same period.

And the climate crisis is not just about CO2 emissions. It is about a whole range of environmental justice and democracy issues that need to be considered. And nuclear energy does not have a stellar record in this regard.

For instance, uranium mining – the initial step in nuclear energy production – has been linked to habitat destruction, soil and water contamination, and adverse health effects for communities near mining sites. The extraction and processing of uranium require vast amounts of energy, often derived from nonrenewable sources, further compromising the environmental credentials of nuclear power.

Nuclear energy also uses centralised technology, governance, and decision-making processes, concentrating the distribution of power in the hands of the few.

For an equitable energy transition, energy solutions need not only to be safe, but justly sourced and fairly implemented. While nuclear power plants require kilometres of pipelines, long-distance planning, and centralised management, the manufacturing and installation of solar panels and wind turbines is becoming more and more energy efficient and easier to deploy.

If implemented correctly, regulation and recycling programnes can address critical materials and end-of-life disposal concerns. Community-based solar and wind projects can create new jobs, stimulate local economies, and empower communities to take control of their energy future as opposed to contributing more money to the trillion-dollar fossil fuel industry.

Although the 2011 disaster in Fukushima may seem like a distant past, its effects today on the health of its environment, people and community are reminders that we must not be dangerously distracted with the so-called promises of nuclear energy.

We must not transition from one broken system to another.

Wealthy countries have an ethical historical responsibility to support global finance reform and provide ample funding for renewable energy in lower-income countries. To keep our world safe and fair, not only do we need to tax and phase out fossil fuels immediately, but it is essential that we power up with renewable energy, such as wind and solar, fast, widely, and equitably.

Fukushima City: 100 MW solar farm

4 Apr 24,  https://www.pveurope.eu/solar-parks/japan-fukushima-city-100-mw-solar-farm—

Juwi Shizen Energy, the joint venture founded in 2013 between the German project developer Juwi and the Japanese developer of wind and solar parks Shizen Energy, has successfully connected the largest single project in its history to the grid in Fukushima City and has already handed it over to the operator.

Construction of the Azuma Kofuji solar park began in August 2020, and the first kilowatt hour of clean electricity was fed into the grid at the end of September 2022. Annually, the solar park, which is spread over several sub-areas, will produce around 107 million kilowatt hours of electricity. This corresponds to the average consumption of around 31,000 Japanese households.

Juwi Shizen implemented the project as EPC service provider. With the largest project in the joint venture’s history, the project volume implemented since its foundation in 2013 now increases to a total of 602 megawatts. Another 140 megawatts of solar capacity is currently under construction.

Renewable energy plants on abondoned former agricultural land encouraged by law

The completed facility covers an area of approximately 186 acres, most of which is unused farmland. The construction of renewable energy plants on such abandoned former agricultural land is encouraged by law in Japan.

The solar park is located in Fukushima Prefecture, about 80 kilometers from the Fukushima Daiichi nuclear reactor. There, core meltdowns occurred in several reactor units in March 2011 as a result of an earthquake and a tsunami triggered by it, making it one of the largest nuclear disasters in history. (hcn)

The $97 billion mess – spent nuclear fuel reprocessing in Japan

The reprocessing plant was initially scheduled for completion in 1997.

Including expenditures for the future decommissioning of the plant, the total budget has reached 14.7 trillion yen. (close to $97 billion)

Even if the reprocessing plant is completed, it can treat only 800 tons of spent nuclear fuel annually at full capacity, compared with 19,250 tons of spent fuel stored nationwide.

“They have invested too much money in the program to give up on it halfway,“

Another delay feared at nuclear fuel reprocessing plant in Aomori

By AKI FUKUYAMA/ Staff Writer, April 1, 2024,  https://www.asahi.com/ajw/articles/15183716

Long-flustered nuclear fuel cycle officials fear there could be another delay in the project.

In a surprise to hardly anyone, the “hopeful outlook” for completion in June of a spent fuel reprocessing plant, a key component in Japan’s nuclear fuel cycle project, was pushed back in late January.

The facility is supposed to extract plutonium and uranium from used nuclear fuel. The recycled fuel can then be used to create mixed-oxide (MOX) fuel, which can run certain nuclear reactors.

But the incompletion of the plant has left Japan with 19,000 tons of spent nuclear fuel with nowhere to go.

The nuclear waste stockpile will only grow, as the administration of Prime Minister Fumio Kishida is turning to nuclear energy to cut Japan’s greenhouse gas emissions and reduce the country’s dependence on increasingly expensive fossil fuels.

Under the plan, 25 to 28 reactors will be running by 2030, more than double the current figure. Tokyo Electric Power Co. is seeking to restart reactors at its Kashiwazaki-Kariwa nuclear power plant in Niigata Prefecture this year.

31 YEARS AND COUNTING

A sign reading “village of energy” stands near Japan Nuclear Fuel Ltd.’s nuclear fuel reprocessing plant in Rokkasho, Aomori Prefecture.

The site, which is 159 times the size of Tokyo Dome, is lined with white buildings with no windows.

Construction started 31 years ago. It was still being built in late November last year, when it was shown to reporters.

The reprocessing plant is located on the Shimokita Peninsula at the northern tip of the main Honshu island.

Crops in the area are often damaged by cold humid winds during summer, so Rokkasho village accepted the plant in 1985 for local revitalization in place of agriculture.

Employees of privately-run Japan Nuclear Fuel, which is affiliated with nine major power companies, and other industry-related personnel account for more than 10 percent of Rokkasho’s population.

After repeated readjustments to the schedule, Naohiro Masuda, president of Japan Nuclear Fuel, said in December 2022 that the plant’s completion should come as early as possible during the first half of fiscal 2024, which is April to September 2024. More specifically, he pointed to “around June 2024.”

But at a news conference on Jan. 31 this year, Masuda said it is “inappropriate to keep saying the plant will be completed in June.”

The reprocessing plant was initially scheduled for completion in 1997.

Many insiders at the plant say it will be “quite difficult” to complete the work within the first half of fiscal 2024.

If officially decided, it will be the 27th postponement of the completion. 

PROLONGED SCREENING, ACCIDENTS

One of the reasons for the delay of the completion is prolonged screenings by the Nuclear Regulation Authority. 

Flaws were identified one after another in the company’s documents submitted to the nuclear watchdog, and around 400 Japan Nuclear Fuel employees are working on the papers within a gymnasium at the plant site.

Mechanical problems have also hampered progress. In 2022, for example, a system to cool high-level radioactive liquid waste broke down.

Masuda visited industry minister Ken Saito on Jan. 19 to report on the situation at the plant.

Saito told Masuda about the construction, “I expect you to forge ahead at full tilt.”

Masuda stressed his company “is fully devoted to finishing construction as soon as possible,” but said safety “screening is taking so much time because we have myriad devices.”

The cost to build the reprocessing plant, including new safety measures, has ballooned to 3.1 trillion yen ($20.57 billion), compared with the initial estimate of 760 billion yen.

Including expenditures for the future decommissioning of the plant, the total budget has reached 14.7 trillion yen. (close to $97 billion)

Even if the reprocessing plant is completed, it can treat only 800 tons of spent nuclear fuel annually at full capacity, compared with 19,250 tons of spent fuel stored nationwide.

Kyushu Electric Power Co. said in January that it would tentatively suspend pluthermal power generation at the No. 3 reactor of its Genkai nuclear power plant in Saga Prefecture. The reactor uses MOX fuel.

Kyushu Electric commissioned a French company to handle used fuel, but it recently ran out of stocks of MOX fuel.

Kyushu Electric has a stockpile of plutonium in Britain, but it cannot take advantage of it because a local MOX production plant shut down.

HUGE INVESTMENT

Calls have grown over the years to abandon the nuclear fuel cycle project.

Many insiders of leading power companies doubt whether the reprocessing plant “will really be completed” at some point.

But the government has maintained the nuclear fuel cycle policy, despite the huge amounts of time and funds poured into it.

“The policy is retained just because it is driven by the state,” a utility executive said.

Hajime Matsukubo, secretary-general of nonprofit organization Citizens’ Nuclear Information Center, said the government’s huge investment explains why the fuel cycle program has yet to be abandoned.

“They have invested too much money in the program to give up on it halfway,” Matsukubo said.

‘Oppenheimer’ finally opens in Japan, the only nation to experience horror of nuclear war

By Chris Lau and Moeri Karasawa, CNN,  Mon April 1, 2024

Japanese moviegoers finally got the chance to see “Oppenheimer” this weekend, eight months after the biopic’s worldwide release, following concerns over how it might be received in the only country to directly experience the horror of nuclear weapons.

The Oscar-winning blockbuster by British-American director Christopher Nolan was one of 2023’s most successful films and its joint release on the same weekend as “Barbie” created a global movie spectacle dubbed “Barbenheimer.”

But that framing left many Japanese people feeling uncomfortable — as did the painful content of a movie that centers on the devastating technology unleashed by J. Robert Oppenheimer and his team of scientists.

Some in Japan felt that the unofficial “Barbenheimer” marketing campaign trivialized the 1945 nuclear attacks on Hiroshima and Nagasaki, and studio Universal Pictures opted not to include the country in its global release rollout last July.

The three-hour biopic has broken several records since its release last year, becoming the highest-grossing movie set during World War II, according to Universal.

In Japan, it ranked fourth at the box office following its release Friday, according to industry tracker Kogyo Tsushinsha, raking in 379 million yen ($2.5 million) in its first three days.

As part of its promotional campaign, Universal sought the views of atomic bomb survivor Tomonaga Masao, who is the president of a Nagasaki-based “hibakusha” group — the name survivors call themselves. In quotes published on the movie’s official Japanese website, Masao said could feel the titular character’s struggle in the latter part of the film, when Oppenheimer begins to push back against the nuclear arms race that emerges after the war.

“This is… connected to the fundamental problem of the world today, where a nuclear-free world is becoming more and more distant,” he is quoted as saying

“Here we sense Nolan’s hidden message of pursuing the responsibility of politicians,” he added.

Former Hiroshima Mayor Hiraoka Takashi is meanwhile quoted saying that he saw “a man full of contradictions,” whose scientific work was weaponized by the state and whose warning against downplaying the threat of nuclear war was later ignored by those same authorities.

“The atmosphere of those days still fills our world today,” he said, adding: “I would like to watch it again and think about what a nation that believes in nuclear deterrence is”

……………………………………………………………………………………

Rishu Kanemoto, a 19-year-old student, saw the film on Friday.

“Hiroshima and Nagasaki, where the atomic bombs were dropped, are certainly the victims,” he told Reuters.

But he also expressed sympathy for Oppenheimer.

“I think even though the inventor is one of the perpetrators, he’s also the victim caught up in the war,” he added.  https://edition.cnn.com/2024/04/01/style/japan-oppenheimer-release-nuclear-intl-hnk/index.html

Oppenheimer: Monaghan man, Daniel A. McGovern, who captured nuclear devastation

By Adam Mandeville, BBC News NI 31 Mar 24

The success of the film Oppenheimer has shone a spotlight once more on the bombings of Hiroshima and Nagasaki.

However, the story of one Monaghan man involved in the aftermath appears to have been forgotten.

Just one month after the bombings, Lt Col Daniel A. McGovern was the first person sent by the US to document the damage.

A member of the US Airforce, he was a specialist cameraman trained to document bombs and their aftermath.

In one scene in the Academy Award winning Oppenheimer film, the titular character played by Irish man Cillian Murphy looks in horror at footage of the aftermath of the bombing.

But these images may not have survived for others to see if it were not for one man from Carrickmacross.

McGovern’s biographer said the story is one of most amazing he has ever heard.

“McGovern’s story is better, in my opinion, than Oppenheimer’s,” he said.

In total, Col McGovern’s team collected over 125,000ft of colour and black and white footage – though much of this was classified.

When he returned from Japan, Col McGovern made secret copies of the footage to ensure it would be saved from US government censorship.

He took these from the Pentagon, storing one set at an air force motion picture depository in Dayton, Ohio, and kept the other himself.

In 1967, a US Congressional committee, that included Robert Kennedy, asked to see the atomic bomb footage.

The material had been declassified but no one could find the originals.

Col McGovern directed the authorities to his copies.

In 1970, the general public got its first glimpse of some of the footage as it was incorporated into a film called Hiroshima Nagasaki – August 1945.

McGovern’s huge risk to secretly keep copies of his footage ensured that the committee had access to crucial documents.

Joseph McCabe spent 20 years working on a biography of Col McGovern, called Rebels to Reels: A Biography of Combat Cameraman Daniel A. McGovern USAF.

He said Col McGovern could have been shot for treason after making copies of the classified footage, but did so to save it for future generations…………………………………………………..

Mr McCabe suggested the footage watched by J Robert Oppenheimer would have been captured by McGovern.

Historian Dr Tom Thorpe said without the footage captured by McGovern, films such as Oppenheimer may never have been made.

“McGovern’s actions to save the footage ensured that it remained available for future generations,” he said.

“[McGovern’s] contributions indirectly influenced the availability of such archival material for films like Oppenheimer.”

He added that the images are “immensely important to our understanding of history”.

…………………………………………………………………….. In the latter half of the 20th Century, Col McGovern would continue to work for the US military and government, photographing various bomb tests, including those of Wernher Von Braun, co-developer of the V2 rocket.

He was also asked to help gather footage in and around Roswell, New Mexico following the now famous Roswell incident.

Col Daniel A McGovern passed away in California in 2005.

In 2022, 100 years after the McGovern family left for the US, his family returned to Carrickmacross to witness the unveiling of a commemorative plaque, dedicated to the man who photographed one of the most infamous events of the 20th Century.  https://www.bbc.com/news/uk-northern-ireland-68656372

Japan confirms experts met in China to ease concerns over discharge of treated radioactive water

Japan said Sunday its experts have held talks with their Chinese
counterparts to try to assuage Beijing´s concerns over the discharge of
treated radioactive wastewater from the wrecked Fukushima Daiichi nuclear
power plant into the sea. The discharges have been opposed by fishing
groups and neighboring countries especially China, which banned all imports
of Japanese seafood. China´s move has largely affected Japanese scallop
growers and exporters to China. During the talks held Saturday in the
northeastern Chinese city of Dalian, Japanese officials provided
“science-based” explanation of how the discharges have been safely carried
out as planned, according to the Japanese Foreign Ministry.

Experts from Japan and China held talks on treated radioactive wastewater

 Experts from Japan and China held talks on treated radioactive wastewater
being released from the Fukushima No. 1 nuclear power plant, the Foreign
Ministry in Tokyo said late Saturday, in the first public announcement of
such a meeting.

The two Asian powerhouses have faced off over the issue
since Japan began releasing the water into the Pacific Ocean last August,
with Beijing — a major importer of Japanese seafood — slapping a ban on
all such products immediately after.

Court Allows Ageing Japanese Nuclear Plants to Continue Operations

By Tsvetana Paraskova – Mar 29, 2024,   https://oilprice.com/Latest-Energy-News/World-News/Court-Allows-Ageing-Japanese-Nuclear-Plants-to-Continue-Operations.html

A Japanese district court on Friday rejected petitions from residents and allowed five ageing nuclear reactors in central Japan to continue operations. 

The five reactors at the plants, operated by Kansai Electric Power Co in the Fukui Prefecture on the Sea of Japan coast, began commercial operations between the mid-1970s and mid-1980s. 

Local residents had asked the Fukui District Court to grant injunctions for the operations of one reactor at the Mihama nuclear plant and four reactors at the Takahama power plant, citing inadequate safety measures. 

The court, however, denied the injunctions, thus allowing the five reactors to continue operations. 

More than a decade after the Fukushima disaster, public opinion continues to be generally negative toward an en masse return to nuclear power, but Japanese authorities are keen to avoid energy crises and are betting on re-opening more nuclear power plants. 

Following the Fukushima disaster in 2011, Japan closed all of its nuclear power plants for rigorous safety checks and inspections. The country has been returning reactors in service in recent years. 

Japan is bringing back nuclear power as a key energy source, looking to protect its energy security in the wake of the energy crisis that led to surging fossil fuel prices. The resource-poor country which needs to import about 90% of its energy requirements, made a U-turn in its nuclear energy policy at the end of 2022, as its energy import bill soared amid the energy crisis and surging costs to import LNG at record-high prices.

The Japanese government confirmed in December 2022 a new policy for nuclear energy, which the country had mostly abandoned since the Fukushima disaster. A panel of experts under the Japanese Ministry of Industry has also decided that Japan would allow the development of new nuclear reactors and allow available reactors to operate after the current limit of 60 years.

Japan finishes first-year ocean discharge of nuclear-tainted wastewater amid backlash

“All fishermen are against ocean dumping. The contaminated water has flowed into what we fishermen call ‘the sea of treasure’, and the process will last for at least 30 years,“

“There is no good reason to dump radioactive materials into the ocean. There is no reason to just dilute them and flush them away,“

https://thesun.my/world/japan-finishes-first-year-ocean-discharge-of-nuclear-tainted-wastewater-amid-backlash-PD12227910 18 Mar 24,

TOKYO: Despite opposition and concern from at home and abroad, Japan’s crippled Fukushima Daiichi Nuclear Power Plant has finished its initial year of discharging nuclear-contaminated wastewater into the ocean, according to the plant’s operator, said Xinhua.

As per the initial plan, approximately 31,200 tons of wastewater, containing radioactive tritium, was released into the ocean since the discharge started in August 2023, with each round of discharge carried out for about two weeks. Earlier this week, International Atomic Energy Agency Director-General Rafael Grossi emphasised continued efforts in monitoring Japan’s ocean discharge of nuclear-contaminated wastewater from the crippled plant, following his first visit to Fukushima prefecture since the discharge started.

Stressing that the discharge marks merely the initial phase of a long process, Grossi said that “much effort will be required in the lengthy process ahead,“ and reiterated the organisation’s stance on maintaining vigilance throughout the process.

While the Japanese government and TEPCO have asserted the safety and necessity of the discharge, concerns have been raised by neighbouring countries and local stakeholders regarding environmental impacts.

“All fishermen are against ocean dumping. The contaminated water has flowed into what we fishermen call ‘the sea of treasure’, and the process will last for at least 30 years,“ said Haruo Ono, a fisherman in the town of Shinchi in Fukushima.

“There is no good reason to dump radioactive materials into the ocean. There is no reason to just dilute them and flush them away,“ said the man in his 70s.

“Is it really necessary, in the first place, to dump what has been stored in tanks into the sea? How can we say it’s ‘safe’ when the discharged water clearly consists of harmful radioactive substances? I think the government and TEPCO must provide a solid answer,“ said Chiyo Oda, a resident of Fukushima’s Iwaki city.

Concerns were fuelled among the Japanese public over the recent leakage of contaminated water from pipes at the Fukushima plant. – Bernama, Xinhua

Fourth discharge of treated Fukushima water completed

 The release of the fourth batch of treated radioactive water from the

Concerns and complaints continue as fourth Fukushima wastewater discharge completed

 https://news.cgtn.com/news/2024-03-18/Concerns-continue-as-fourth-Fukushima-wastewater-discharge-completed-1s4JAJ539w4/p.html

Concerns and complaints from home and abroad remain while Japan’s crippled Fukushima Daiichi Nuclear Power Plant has finished its first year of discharging nuclear-contaminated wastewater into the ocean.

The plant completed its fourth and final round of discharge for the current fiscal year, which ends in March, Tokyo Electric Power Company (TEPCO) said on Sunday.

As per the initial plan, approximately 31,200 tonnes of wastewater containing radioactive tritium has been released into the ocean since August 2023, with each discharge running for about two weeks.

Earlier this week, International Atomic Energy Agency Director-General Rafael Grossi emphasized continued efforts to monitor the discharging process.

Stressing that the discharge marks merely the initial phase of a long process, Grossi said that “much effort will be required in the lengthy process ahead,” and reiterated the organization’s stance on maintaining vigilance throughout the process.

While the Japanese government and TEPCO have asserted the safety and necessity of the process, there are still concerns from other countries and local stakeholders regarding environmental impacts.

Sophia from the U.S. complained that the release of nuclear-contaminated water into the sea made her fear for the future.

Najee Johnson, a college student from Canada, suggested the Japanese government find a different plan because it could pollute our ocean and harm our sea life.

Haruo Ono, a fisherman in the town of Shinchi in Fukushima, said “All fishermen are against ocean dumping. The contaminated water has flowed into what we fishermen call ‘the sea of treasure’, and the process will last for at least 30 years.”

“Is it really necessary, in the first place, to dump what has been stored in tanks into the sea? How can we say it’s ‘safe’ when the discharged water clearly consists of harmful radioactive substances? I think the government and TEPCO must provide a solid answer,” said Chiyo Oda, a resident of Fukushima’s Iwaki city.

The recent leakage of contaminated water from pipes at the Fukushima plant also fueled concerns among the Japanese public.

Besides, the promised fund of more than 100 billion yen (around $670 million) to compensate and support local fishermen and fishing industry remains doubtful as a court ruling last December relieved the government of responsibility to pay damages to Fukushima evacuees.

A Tokyo court ruled that only the operator of the tsunami-wrecked Fukushima nuclear power plant has to pay damages to the evacuees, relieving the government of responsibility. Plaintiffs criticized the ruling as belittling their suffering and the severity of the disaster. The court also slashed the amount by ordering the TEPCO to pay a total of 23.5 million yen to 44 of the 47 plaintiffs.

The ruling backpedaled from an earlier decision in March 2018, when the Tokyo District Court held both the government and TEPCO accountable for the disaster, which the ruling said could have been prevented if they both took better precautionary measures, ordering both to pay 59 million yen in damages.

IAEA director’s visit to Japan widely questioned, seeks to downplay nuclear water dumping

Global Times, By Xu Yelu and Xing Xiaojing Mar 15, 2024

Rafael Grossi, director general of the International Atomic Energy Agency (IAEA), said during his visit to Japan that he confirmed that the “treated water” in Fukushima fully meets international standards, and experts believe such remarks supporting the discharge have become a kind of “political security” reached between the Japanese government and the IAEA.

Grossi was in Japan visiting the site of the nuclear power plant for the first time since the water dumping began. He also attended a meeting in Fukushima where representatives of the government and fishing communities discussed the current situation, according to Kyodo News.

He supported Japan’s decision once again, saying, “Our corroboration and information and also independent sampling have confirmed the very low presence of tritium … In some cases even impossible to trace, which means that the process is working as we thought it will be. So in this regard, it is correct. We are satisfied.”

According to the Japanese newspaper Mainichi Shimbun, Japanese Prime Minister Fumio Kishida and Foreign Minister Yoko Kamikawa separately met with Grossi, confirming continued cooperation on the issue of the discharge. The Japanese side announced that they will provide approximately 18.5 million euros ($20 million) in assistance to the IAEA.

The Chinese Embassy in Japan responded on Thursday that the Japanese side’s forced implementation of discharging nuclear-contaminated wastewater into the sea has no precedent since the peaceful use of nuclear energy by humans, nor are there any recognized disposal standards. How can it be said to comply with so-called “international standards?”

The nuclear-contaminated wastewater generated by the Fukushima nuclear accident contains various radioactive nuclides present in the melted core, many of which do not have effective treatment technologies. Focusing solely on tritium clearly ignores this basic fact………………………….

The IAEA should uphold the principles of objectivity, professionalism, and impartiality, and should not endorse Japan’s erroneous actions of discharging nuclear-contaminated wastewater into the sea, nor should it disseminate one-sided information that misleads international public opinion, the embassy stressed.

………………”With the internal management chaos of Tokyo Electric Power Company and inadequate government supervision in Japan, in a situation where standards are unclear, boundaries are unclear, and data is not transparent, no one or organization can guarantee that the nuclear-contaminated wastewater being discharged into the ocean by Japan is safe,” Zhang said.

…………………………….the plan to discharge Fukushima’s contaminated water into the sea will last for 30 years. However, since the first round of discharge, it has been less than seven months, and the IAEA has expressed “satisfaction” with the discharge situation. Or, it can be said that this is a kind of “political security” reached between the Japanese government and the IAEA.

Japan Ramps Up Drive to Restart World’s Biggest Nuclear Plant

Stephen Stapczynski and Aya Wagatsuma, Bloomberg News, 15 Mar 24  

Japan’s government is ramping up an effort to secure local approval to resume operations at the world’s biggest nuclear power plant, according to a report, amid a wider push by the nation to restart its idled fleet of reactors.

Minister of Economy, Trade and Industry Ken Saito will next week request Niigata Governor Hideyo Hanazumi to endorse the restart of Tokyo Electric Power Co’s Kashiwazaki-Kariwa nuclear power station, according to the Niigata Nippo newspaper. METI didn’t respond to a request for comment.

The governor’s approval is one of the last hurdles before the nuclear plant can resume…………………………….

The head of the International Atomic Energy Agency this week said that the organization would provide technical assistance for the plant, and send a team of experts to assist Tepco’s effort to gain public trust.

Kashiwazaki Kariwa, which has seven reactors totaling 8.2 gigawatts in capacity, is located about 250 kilometers (155 miles) north of Tokyo. The nation’s regulator said in 2017 that reactor units 6 and 7 met post-Fukushima safety protocols.

Conditions inside Fukushima’s melted nuclear reactors still unclear 13 years after disaster struck

The contents of the three reactors is still largely a mystery. Little is known, for instance, about the melted fuel’s condition or exactly where it’s located in the reactors. Not even a spoonful of the fuel has been removed

About 880 tons of melted nuclear fuel remain inside the three damaged reactors, and Japanese officials say removing it would take 30-40 years. Experts call that timeline overly optimistic. The amount of melted fuel is 10 times that removed from Three Mile Island following its 1979 partial core melt.

MARI YAMAGUCHI, TOKYO, THE ASSOCIATED PRESS, March 11, 2024,  https://www.theglobeandmail.com/world/article-conditions-inside-fukushimas-melted-nuclear-reactors-still-unclear-13/—

Japan on Monday marked 13 years since a massive earthquake and tsunami hit the country’s northern coasts. Nearly 20,000 people died, whole towns were wiped out and the Fukushima Daiichi nuclear power plant was destroyed, creating deep fears of radiation that linger today. As the nation observes the anniversary, the AP explains what is happening now at the plant and in neighboring areas.

What happened 13 years ago?

A magnitude 9.0 earthquake struck on March 11, 2011, causing a tsunami that battered northern coastal towns in Iwate, Miyagi and Fukushima prefectures. The tsunami, which topped 15 meters (50 feet) in some areas, slammed into the nuclear plant, destroying its power supply and fuel cooling systems, and causing meltdowns at reactors No. 1, 2 and 3.

Hydrogen explosions caused massive radiation leaks and contamination in the area.

The operator, Tokyo Electric Power Company Holdings, says that the tsunami couldn’t have been anticipated. Government and independent investigations and some court decisions have said the accident was the result of human error, safety negligence, lax oversight by regulators and collusion.

Japan has since introduced stricter safety standards and at one point shifted to a nuclear energy phaseout. Prime Minister Fumio Kishida’s government reversed that policy and has accelerated restarts of workable reactors to maintain nuclear power as a main source of Japan’s power supply.

A deadly Jan. 1 earthquake in Japan’s northcentral region destroyed many homes and roads but didn’t damage an idled nuclear power plant. Even so, it caused worry that current evacuation plans that solely focus on radiation leaks could be unworkable.

The nation marked a moment of silence at 2:46 p.m. Monday, with Kishida attending a memorial in Fukushima.

What happened to people in the area?

About 20,000 of more than 160,000 evacuated residents across Fukushima still haven’t returned home.

Decontamination work before the Tokyo Olympics meant to showcase Fukushima’s recovery led to the elimination of some no-go zones, but they remain in seven of 12 towns that had been fully or partially off-limits.

In Futaba, the hardest-hit town and a co-host of the Fukushima Daiichi plant, a small area was opened in 2022. About 100 people, or 1.5% percent of the pre-disaster population, have returned to live. The other host town, Okuma, which along with Futaba sacrificed part of its land to build an interim storage site for nuclear waste gathered from the decontamination, has seen 6% of its former residents return.

Annual surveys show the majority of evacuees have no intention of returning home, citing lack of jobs, schools and lost communities, as well as radiation concerns.

Residents who have raised radiation worries or linked it to their health problems have come under attack for hurting Fukushima’s reputation.

The disaster-hit towns, including those in Iwate and Miyagi prefectures, have seen sharp population drops.

Fukushima Gov. Masao Uchibori said on NHK TV that a growing number of young people want to move to Fukushima to open businesses or help in the reconstruction, and he expressed hope that more residents will return.

What about treated radioactive water discharges?

Last August, Fukushima Daiichi began discharging treated water into the sea, and is currently releasing a fourth 7,800-ton batch of treated water. So far, daily seawater sampling results have met safety standards. The plan has faced protests from local fishers and neighboring countries, especially China, which has banned Japanese seafood imports.

Fukushima Daiichi has struggled to handle the contaminated water since the 2011 meltdowns. TEPCO says the start of the process is a milestone and removing the tanks is crucial to make space for facilities needed as decommissioning progresses.

The contaminated cooling water is pumped up, treated and stored in about 1,000 tanks. The government and TEPCO say the water is diluted with massive seawater before release, making it safer than international standards.

What about local fishing?

Despite earlier fears that the water discharge would further hurt Fukushima’s hard-hit fishing industry, they have not damaged its reputation domestically. China’s ban on Japanese seafood, which mostly hit scallop exporters in Hokkaido, apparently prompted Japanese consumers to eat more Fukushima seafood.

Sampling and monitoring by the International Atomic Energy Agency have also boosted confidence in local fish.

Fukushima fishing returned to normal operations in 2021, and the local catch is now about one-fifth of its pre-disaster level because of a decline in the fishing population and smaller catch sizes.

The government has earmarked 10 billion yen ($680 million) to support Fukushima fisheries.

Any progress removing melted fuel?

The contents of the three reactors is still largely a mystery. Little is known, for instance, about the melted fuel’s condition or exactly where it’s located in the reactors. Not even a spoonful of the fuel has been removed.

About 880 tons of melted nuclear fuel remain inside the three damaged reactors, and Japanese officials say removing it would take 30-40 years. Experts call that timeline overly optimistic. The amount of melted fuel is 10 times that removed from Three Mile Island following its 1979 partial core melt.

Robotic probes have glimpsed inside the three reactors, but their investigation has been hampered by technical glitches, high radiation and other complications.

It’s crucial for officials to understand the data from melted debris so they can make a plan to remove it safely. TEPCO aims to get the first sample out later this year from the least-damaged No. 2 reactor.

TEPCO has been trying to get the sample by using a robotic arm. Officials have struggled to get the robot past the wreckage, and hope that by October they can use a simpler device that looks like a fishing rod.

The fuel in the worst-damaged No. 1 reactor mostly fell from the core to the bottom of its primary containment vessel. Some of it penetrated and mixed with the concrete foundation, making removal extremely difficult.

In February, the plant made its first drone flight into the primary containment vessel to investigate the melted debris and examine how the fuel initially fell from the core. But a second day of exploration was canceled because a data transmission robot failed.

Is a 2051 completion possible?

The government has stuck to its initial target for a completed decommissioning by 2051, but it hasn’t defined what that means.

The lack of data, technology and plans on what to do with the radioactive melted fuel and other nuclear waste makes it difficult to understand what’s in store for the plant and surrounding areas when the cleanup ends, according to TEPCO’s decommissioning company chief, Akira Ono.

An overly ambitious schedule could result in unnecessary radiation exposure for plant workers and excess environmental damage, experts say.

Japan’s Nuclear Energy Policy Disaster

The yawning gap between vision and policy reality jeopardizes Japan’s important energy security goals and efforts to decarbonize the energy supply.

By Florentine Koppenborg, March 08, 2024,  https://thediplomat.com/2024/03/japans-nuclear-energy-policy-disaster/

The Japanese government is chasing a nuclear mirage 13 years after the Fukushima Daiichi nuclear disaster in March 2011. Government statements in support of nuclear power, such as the recent declaration at COP28 that Japan will triple nuclear energy by 2050, receive much attention. Away from the public spotlight, however, Japan is facing a nuclear energy policy disaster as it struggles to actually return to nuclear energy after the Fukushima nuclear accident.

As the Japanese government pursues a nuclear revival to no avail, the yawning gap between vision and policy reality jeopardizes important energy policy goals such as energy security and decarbonizing energy supply.

The share of nuclear power in Japan’s electricity mix has stagnated between 5 and 8 percent since 2018, and the goal to generate 20–22 percent of electricity from nuclear by 2030 has become elusive. Japan’s fleet of commercial nuclear reactors, once the third largest in the world at 54 units, has diminished to 33 plus two units currently under construction. Restarting these 35 reactors would barely be enough to meet the government’s 2030 targets. However, only 27 reactors are undergoing the safety reviews required for a restart permit. If successful, they can provide about 14 percent of Japan’s electricity mix by 2030, far from the government’s goals. 

Actual restart progress is even more bleak, with only 12 reactors back on the grid by early 2024. Plans to start using the Onagawa plant’s reactor number two for electricity generation in May 2024 had to be postponed to September due to delays in additional safety construction work. For the Tokai reactor number two, work on safety measures is scheduled to conclude in September 2024, but it remains to be seen whether construction will finish on time. With the restart process riddled with setbacks and uncertainties, the total number of reactors actually generating electricity looks to increase only marginally over the next few years. 

One potential solution to this problem, constructing new reactors, takes at least a decade and risks public backlash as safety concerns linger. The recent Noto earthquake was a reminder of safety risks as the earthquake partly exceeded assumptions made in safety checks and led to questions about the adequacy of emergency evacuation plans. Removing the official 40-year lifespan limit on nuclear reactors – introduced as a major safety lesson after the 2011 nuclear disaster – as part of Japan’s so-called GX (green transformation) strategy that will guide the country’s decarbonization appears as a rather desperate and potentially risky measure. The next generation of modular reactors stressed in the COP28 declaration on nuclear and the GX strategy are not even market-ready technology at the moment. 

Japan’s nuclear energy revival is supposed to increase energy security and drive decarbonization. Chasing unattainable goals, however, has the exact opposite effect as the yawning implementation gap is continuously filled with fossil fuel imports. 

It is time to embrace the solution at hand: expanding renewable energy capacity. 

Increasing energy security has been a major goal of Japan’s energy policy ever since the oil shock in the 1970s. Dependence on fossil fuel imports, already high at 81 percent in 2010, shot up once all of the nuclear power plants were shut down following the Fukushima accident. What brought it down again to about 83 percent in 2021 was not nuclear restarts, but rather an increasing share of renewable energy. Nuclear power and renewable energy have essentially switched places in Japan’s energy mix as renewables increased from 4 percent in 2010 to 11 percent in 2021 and nuclear decreased from 10 percent in 2010 to 3 percent in 2021.   

Additional coal and gas imports to fill the nuclear power gap not only keep Japan’s import dependence high, but also have a substantial impact on its greenhouse gas emissions. Aside from a small share of nuclear energy, low-carbon electricity mainly comes from renewables, which have seen an impressive annual growth at about 16 percent since 2012. The remaining 72 percent come from fossil fuels. Once a climate leader in the 1990s, the current nuclear energy disaster solidifies Japan as a fossil fuel champion rather than a decarbonization leader.

In 2024, the Japanese government has an opportunity to turn things around. Japan’s Strategic Energy Plan, revised every three years, is due again. This presents an opportunity for the government to increase its renewable energy target, ideally in line with the international commitment made at COP28 to triple renewable energy capacity by 2050, and to reduce its nuclear power target accordingly. This would be the best way to alleviate Japan’s current nuclear energy policy disaster and to put the country back on track in its pursuit of energy security and decarbonization.
