About 300 earth science specialists have released a statement calling for a fundamental review of the Japanese government’s plan for storing spent nuclear fuel.

The process for finding a final storage site in Japan has been proceeding “while keeping a lid on scientific discussions,” said Junji Akai, a professor emeritus of earth science at Niigata University, who signed the statement, at an Oct. 30 news conference.

The current plan is to bury the highly radioactive waste deep underground.

But the statement about 300 scientists signed, including a number of former chairmen of the Geological Society of Japan, said there was no place in Japan where such waste could be kept safe for the 100,000 years or so needed for the radiation to dissipate.

A law passed in 2000 regarding the final handling of nuclear waste stated that the spent nuclear fuel should be buried deep underground.

But the statement released on Oct. 30 noted that several tectonic plates converge on the Japanese archipelago, a mobile belt with active volcanoes and frequent earthquakes.

It went on to say that under the current circumstances, it would be “impossible” to choose a location that would not be affected by such tectonic activity for 100,000 years.

The statement called for abolishing the law on the final storage of nuclear waste and setting up a third-party organization to reconsider how such waste should be stored, including temporarily storing it aboveground.

Two small municipalities in Hokkaido are in the first of a three-stage process to determine their suitability as a site for the final storage of nuclear waste. #nuclear #antinuclear #nuclearfree #NoNuke

Two more Japanese nuclear reactors granted 20-year extensions

https://www3.nhk.or.jp/nhkworld/en/news/20231101_21/

Japan’s nuclear watchdog has approved extending the operation of two aging nuclear reactors in southwestern Japan for another 20 years.

The operational lifespan of Japanese reactors has been limited to 40 years in principle since the Fukushima Daiichi nuclear plant accident in 2011. But it can be extended by up to 20 years if the reactors pass screening by the Nuclear Regulation Authority.

At a meeting on Wednesday, the NRA granted extension approval to the No.1 and 2 reactors at the Sendai nuclear power plant in Kagoshima Prefecture, which is operated by the Kyushu Electric Power Company.

The No.1 reactor will turn 40 next July and the No.2 will reach that age in November 2025.

Discussed at the meeting were the results of special inspections of the reactors conducted by Kyushu Electric and an assessment that showed the reactors can be used for another 20 years.

The members of the meeting unanimously approved the extensions.

This decision brings the number of Japanese reactors whose operations have been extended beyond 40 years to six. The other four are the No.1 and No.2 reactors at the Takahama nuclear power plant and the No.3 reactor at the Mihama plant — all in Fukui Prefecture — as well as the Tokai No.2 plant’s reactor in Ibaraki Prefecture. #nuclear #antinuclear #nuclearfree #NoNukes

3-day evacuation drill at Niigata nuclear plant called ‘useless’

THE ASAHI SHIMBUN, October 30, 2023

Residents said their safety concerns have still not been addressed following a three-day government-led drill simulating a serious accident at the Kashiwazaki-Kariwa nuclear power plant in Niigata Prefecture.

They said the drill, which concluded on Oct. 29, showed that there are no measures in place to ensure a smooth evacuation in heavy snow or to prevent traffic congestion caused by radiation checks.

Around 1,400 residents joined the drill, which assumed a magnitude-7.6 earthquake off the prefecture caused a loss of cooling functions at reactors of the plant, which is operated by Tokyo Electric Power Co.

This was the first government-run drill at the seven-reactor Kashiwazaki-Kariwa nuclear plant since the 2011 disaster at TEPCO’s Fukushima No. 1 nuclear power plant caused by the Great East Japan Earthquake and tsunami.

At the end of last year, main evacuation routes, including in Kashiwazaki, where the plant is located, were closed for up to 52 hours due to heavy snowfall…………………………………………………………….. more https://www.asahi.com/ajw/articles/15042691— #nuclear #antinuclear #nuclearfree #NoNukes

Fukushima nuclear plant workers sent to hospital after being splashed with tainted water

Guardian, 27 Oct 23

The operator Tepco says the workers came in contact with the wastewater when a hose came off accidentally and have been taken to hospital as a precaution

Four workers at the Fukushima nuclear plant were splashed with water containing radioactive materials, with two of them taken to hospital as a precaution, according to the plant operator.

The incident, which took place on Wednesday, highlights the dangers Japan still faces in decommissioning the plant. The reactor was knocked out by an immense tsunami in 2011 in the world’s worst atomic disaster since Chornobyl in 1986.

Five workers were cleaning pipes at the system filtering wastewater for release into the sea when two were splashed after a hose came off accidentally, according to a spokesperson for operator Tepco.

Two others were contaminated when they were cleaning up the spill, the spokesperson added………

Tepco said that both would stay in hospital for “about two weeks” for follow-up examinations and that the company was analysing how the accident had occurred while reviewing measures to prevent a repeat of it………………………

Mechanism for toxic radioactive water release sought

“What I find problematic is that TEPCO, the Japanese government and the IAEA are not addressing the long-term environmental impacts and the accumulation in the environment resulting from individual data. In the case of long-term releases, there is a concern about accumulation in the marine environment and concentration through the ecosystem, but this aspect is not being adequately evaluated.”

By JIANG XUEQING in Tokyo 2023-10-24 https://global.chinadaily.com.cn/a/202310/24/WS65372116a31090682a5ea51d.htmll

Experts urge long-term intl monitoring and participation of all stakeholders

Experts call for the establishment of a long-term international monitoring mechanism with substantive participation from stakeholders, as Japan and the International Atomic Energy Agency are both criticized for not addressing the long-term environmental impacts of the dumping of nuclear-contaminated water into the sea.

The IAEA is sending its team to Japan to continue its safety review of the release from the crippled Fukushima Daiichi Nuclear Power Plant.

Starting Tuesday, the IAEA will conduct a safety review of the activities carried out at the Fukushima plant to make sure these activities are consistent with the international safety standards, said Lydie Evrard, IAEA deputy director-general and head of the agency’s department of nuclear safety and security.

A report on the review is expected to be finalized by the end of 2023, she told a news conference in Tokyo on Monday.

Chinese Foreign Ministry spokesman Wang Wenbin on Oct 11 said the collection of marine samples near Fukushima, analysis by laboratories and comparison of those samples were carried out by the IAEA Secretariat under its bilateral arrangement with Japan. Therefore, he said, it falls short of an international monitoring arrangement with the full and substantive participation of all stakeholders.

“The international community requires the immediate establishment of an international monitoring arrangement with substantive participation of all stakeholders, including Japan’s neighboring countries, that will stay effective for the long haul,” Wang said, urging the IAEA to play its due role and take the responsibility of providing rigorous supervision on Japan’s discharge.

The key issue is how to establish an international monitoring mechanism for the real-time and long-term effective management of nuclear-contaminated water being discharged, said Zhang Yulai, vice-president of the Japan Institute of Nankai University.

Major challenge

“Information disclosure is a major challenge because the Japanese government and TEPCO share common interests, making genuine monitoring difficult,” he said.

There are also technical challenges, as certain radionuclides that the Advanced Liquid Processing System cannot remove still exist, he said.

Fukushima plant operator TEPCO announced pre-discharge test results on Thursday, showing that the third batch of nuclear-contaminated water to be released during Japan’s next round of ocean discharge contains seven radionuclides, namely tritium, carbon-14, cobalt-60, strontium-90, yttrium-90, iodine-129 and cesium-137. Among them, strontium-90 and yttrium-90 were not detectable before the second round of discharge.

The measured quantity of strontium is relatively low, but given its 29-year half-life, it will persist in the environment to a certain extent. Strontium is a significant radionuclide that tends to accumulate in bones when ingested by fish or humans, said Hideyuki Ban, a renowned Japanese nuclear expert and co-director of the Tokyo-based Citizens’ Nuclear Information Center.

“What concerns me is the lack of information about the measurement times and methods. I believe that rapid measurements may lack precision,” Ban said.

Many Japanese said they do not believe the data disclosed by TEPCO and the Japanese government.

Chiyo Oda, co-director of KOREUMI, also known as the Citizens’ Conference to Condemn Further Pollution of the Ocean, said those who have experienced the nuclear disaster have developed distrust in the government and TEPCO.

The promise not to release the water without first understanding the concerns of fishermen and citizens, as stated just before the release, has been disregarded. Though they have announced monitoring results immediately after the release, the data is not trustworthy, Oda said.

“It is evident that the marine environment will be contaminated over a long period of time, and there is potential for long-term impacts on human health,” she said. #nuclear #antinuclear #nuclearfree #NoNukes

A wall of silence: atom bosses remain tight-lipped over Fukushima whistleblower claims

collaboration between the IAEA and the Japanese Government over the Fukushima radioactive water releases was imperative as the continuation of sea dumping regardless of the adverse impact to the marine environment represents a ‘make or break issue’ for the nuclear industry.

Over seven weeks have passed without an acknowledgement or reply to a letter the UK/Ireland Nuclear Free Local Authorities co-signed which was sent to the UN International Atomic Energy Authority calling for transparency over claims that the organisation collaborated with the Japanese Government to ‘manage the message’ over the ocean dumping of 1.3 million tonnes of radioactive water from the Fukushima nuclear disaster site.

On 28 June, an anonymous whistleblower posted a document, seemingly issued by the Department of Nuclear Safety at the IAEA, to the website/blogsite dunrenard[1]. If genuine, the document, titled ‘IAEA REVISION PROPOSAL FOR THE FINAL REPORT OF HANDLING ALPS TREATED WATER AT TEPCO’S FUKUSHIMA DAIICHI NUCLEAR POWER STATION’, appears to indicate that the international agency has actively sought to downplay the dangers associated with discharging millions of barrels of water which remain contaminated with highly toxic tritium.

The NFLA’s first covered this story and our disquiet at the revelations in a media release dated 3 July:
https://www.nuclearpolicy.info/news/cover-up-did-atom-bosses-collude-to-manage-message-of-japanese-plan-to-poison-pacific/

One of the recipients of the leaked document was Mr Tim Deere-Jones, a graduate in Marine Studies from Cardiff University. Tim, an independent marine pollution researcher and consultant since 1983, is highly regarded by the many international organisations who have engaged him in their campaigns against the damage caused to our oceans and inland waterways by radioactive and other contaminants.

Tim was incensed that the Japanese Government was quick to condemn the claim that Japan had pressurised the IAEA to remove ‘negative information’ about the environmental impact that would result from the radioactive waste discharges from the final report, but also noted that on the claims themselves the IAEA made no comment.
Keen to seek clarification and action on the veracity of the whistleblower’s claims, Tim went right to the top of the IAEA and penned a letter to the head of the management office for the Deputy Director General. Here he explains why:
“To date there has been no detectable independent action to investigate and test the veracity of the whistleblower’s claims against the claim of non-interference made by the Government of Japan.

“I fear that if this is scenario is allowed to continue the whistleblower’s action and disclosure will be historically characterised by the Government of Japan statement, sink into obscurity and be forgotten and the whistleblower’s heroic action will have been wasted, while he/she is still under threat of investigation, identification, and penalty.
“My disclosure request to the IAEA is intended to elicit a direct response from the agency to the claims made by the whistleblower as to date my online media searches have yet to reveal any related statement made by the organisation.

“This creates the impression that the Government of Japan has been acting as the IAEAs mouthpiece in respect of the whistleblower disclosure and that the IAEA would prefer NOT to be associated in anyway with the issue, to the extent that it has not made any public statement”.

Tim’s request for disclosure, submitted by registered post to the IAEA’s Vienna office and by email to the official account on 1 September, was backed by five British anti-nuclear groups and individuals from Europe and the Pacific Ocean, representing commercial fishers, other marine stakeholders, and coastal zone and Pacific Island communities.

Although the registered letter was tracked as received at the Vienna office on 9 September, Tim has yet to receive any response from the agency, and on 16 October sent a reminder:
“I have concluded that the absence of a receipt or response is a clear indication of the IAEA’s resistance to any discussion of the issues raised.
“My reading critique of the IAEAs final report to TEPCO re the issue of the ALPs treated water release certainly supports the drift of the whistleblower statement”.

Amongst the co-signatories to the letter, which is reproduced at the end of this press release, were the NFLAs, which have objected in letters to Japanese Ministers, senior officials at TEPCO (the nuclear operator), and the United Nations to the discharge of radioactive water from Fukushima, and signed a partnership agreement with its counterparts, Mayors for a Nuclear Power Free Japan, to collaborate in opposing the plan.

Though disappointed at the continued wall of silence, Chair Councillor Lawrence O’Neill is unsurprised that the IAEA remains tight-lipped:

“Sadly, the duties of disclosure required of public bodies in the UK through the Freedom of Information Act do not apply to an international agency based in Vienna and the IAEA’s statutes appear to contain no provisions for transparency or external accountability, despite the agency being funded by the member states, and so the taxpayers, of the United Nations.

“Although the organization claims to want to become more open, the lack of a response, or even an acknowledgement, to our legitimate request for information belies the fact that, on controversial issues, a culture of secrecy still prevails.”
Tim believes that collaboration between the IAEA and the Japanese Government over the Fukushima radioactive water releases was imperative as the continuation of sea dumping regardless of the adverse impact to the marine environment represents a ‘make or break issue’ for the nuclear industry. He has produced a short paper explaining his reasoning, which also appears at the end of this media release.

Decontaminating Fukushima: have the billions spent been worth it?

The Conversation, Jim Smith, Professor of Environmental Science, University of Portsmouth, October 24, 2023

The Chernobyl and (to a lesser extent) Fukushima nuclear accidents contaminated large areas of land with low-level radioactivity. After both accidents, huge efforts were taken to decontaminate the affected areas.

But a recent study at Fukushima raises doubts about whether these decontamination efforts were worthwhile. Less than one-third of the population has returned to the evacuated zones and extensive areas of forest in the region remain contaminated.

Following the accident at Fukushima Daiichi in 2011, approximately 1,100 square kilometres were evacuated, resulting in the relocation of more than 100,000 people from their homes. A contaminated area about eight times larger remained inhabited, albeit subject to continuous radiation monitoring.

The dominant source of radiation exposure for people stemmed from gamma rays emitted by contaminated soils, pavements, roads and buildings. The objective of the decontamination operation was to ensure that the general public received an annual dose from Fukushima’s radioactivity of less than 1,000 microsieverts (µSv) above the natural background level. The average natural radiation dose in Japan stands at 2,200 µSv per year.

Radiocaesium, which is the most important long-lived radioactive element emitted by the accident in terms of radiation dose, adheres to soil particles very strongly. Consequently, the decontamination of agricultural land primarily involved removing the top 5cm of soil. In urban areas, decontamination efforts entailed the removal of topsoil from sports fields, as well as sandblasting or pressure washing hard surfaces, and pressure washing drains and gutters.

These efforts reduced doses by about 60% in residential areas and farmland, allowing people to return to their homes in a large part of the evacuated area. This is a far cry from Chernobyl, where extensive decontamination initiatives were ultimately abandoned, leaving huge evacuated areas that remain empty to this day. But was undertaking decontamination in Fukushima worthwhile?

Costs and benefits

Decontaminating the land in Fukushima has cost tens of billions of dollars. The process has, unfortunately, also caused substantial radiation exposure for the workers involved, and has generated huge amounts of radioactive soil waste. But the question of whether to decontaminate land is complex and only partially related to scientific evidence.

On the one hand, decontamination provides reassurance that radiation is being “cleaned up” and that doses are being reduced. But it can also give the impression that low-level radiation is more dangerous than it actually is.

Dose rates were not dangerously high in many areas of Fukushima that were subject to decontamination. In fact, doses were relatively low in the first year following the accident (less than 12,000 µSv), and these levels decreased significantly in subsequent years.

These levels fall within the natural range people are exposed to from radioactivity in rocks, soils, building materials and cosmic radiation worldwide (typically between 1,000 µSv and 10,000 µSv per year, but sometimes higher).

On balance, I think the reassurance that contamination was being cleaned up was valuable in many areas where people remained living. Decontamination also allowed agricultural land to be returned to productive use more quickly. However, the process of removing topsoil had the side effect of damaging soil fertility.

Accidental rewilding

In the evacuated zone where dose rates were around ten times higher, it’s less clear that decontamination was beneficial. Only 30% of people have returned to their homes in the decontaminated part of this area and much of the land in the most contaminated so-called “difficult to return zone” remains abandoned.

A better option may have been to declare most of this zone a nature reserve and allow managed rewilding of the area. Rewilding is happening to a large extent anyway, as it has at Chernobyl. It would also have avoided decontamination workers being exposed to radiation and allowed more financial support to help people relocate.

But this is a complex decision that needs to consider the views of many stakeholders, not least the evacuated people themselves.

Fukushima’s contaminated forests

The land in and around the region’s towns and villages has generally been decontaminated effectively. However, much of the Fukushima Prefecture (71%) is covered by forest. Most of this forest remains contaminated.

The persistence of radiocaesium in ecosystems, particularly in forests, has been known for many decades. Globally, radiocaesium levels in wild foodstuffs such as mushrooms, edible plants, game animals and freshwater fish tend to be higher than those found in agricultural systems.

Wild boar in certain regions of Germany, for instance, still exhibit radicaesium levels exceeding consumption limits as a consequence of both Chernobyl and historical nuclear weapons testing. Restrictions on the consumption of forest products have lasted for decades following the Chernobyl incident. And they are expected to persist in many forested areas of Fukushima too.

Radiocaesium lingers in forests due to the prevalence of organic soils and the absence of fertiliser application. Low nutrient levels facilitate the absorption of radiocaesium by plants. This is mainly attributed to radiocaesium’s chemical similarity to potassium, a crucial plant nutrient.

Forests do pose a wildfire risk. There have been many forest fires in the vicinity of Chernobyl since the accident. But radiation doses from smoke inhalation are extremely low, even for firefighters, and the fires have not significantly redistributed radioactivity.

There are no easy answers regarding clean up after a nuclear accident. Japan has made huge and often successful efforts to reduce radiation doses and reassure people living in or returning to the affected areas. But low-level radiation remains everywhere, particularly in forests……….. https://theconversation.com/decontaminating-fukushima-have-the-billions-spent-been-worth-it-215836 #nuclear #antinuclear #nuclearfree #NoNukes.

Multiple radionuclides detected in Fukushima nuke wastewater planned for 3rd round of ocean discharge

Xinhua 21 Oct 23 https://www.chinadaily.com.cn/a/202310/21/WS65339e99a31090682a5e9ef2.html

TOKYO — The third batch of Fukushima nuclear-contaminated water to be released during Japan’s next round of ocean discharge contains carbon-14, cobalt 60, strontium-90 and other radionuclides, according to pre-discharge test results released by the Tokyo Electric Power Company (TEPCO).

Despite mounting concerns and opposition among local fishermen as well as from other countries, TEPCO said that preparations for the third round of ocean discharge will begin after the second round of discharge is completed and relevant maintenance and confirmation operations are carried out.

The nuclear-contaminated wastewater from the crippled Fukushima Daiichi nuclear power plant, after advanced liquid processing system (ALPS) treatment, must enter the measurement and confirmation facility and wait for pre-discharge test results before being discharged into the ocean.

The measurement and confirmation facility is split into three groups of 10 tanks with each of the groups used on a rotating basis as receiving tanks, measurement and confirmation tanks, and discharge tanks.

At present, the 10 tanks in Group B were emptied in the first round of discharge starting on Aug 24. Meanwhile, the 10 tanks in Group C were confirmed to meet the discharge standards on Sept 21, and the discharge started on Oct 5.

The sampling of the nuclear wastewater stored in Group A tanks for the third round of discharge was completed on July 10. The analysis results showed that they contained trace amounts of carbon-14, cobalt 60, strontium-90, iodine-129 and cesium-137, of which strontium-90 was not detected in the second round of discharge from Oct 5, according to reports released on Thursday by TEPCO.

TEPCO claims that its ALPS facility, a multi-nuclide removal system, can remove 62 radioactive substances except tritium, but it was found that about 70 percent of the water in the storage tanks contained non-tritium radionuclides at a concentration exceeding the regulatory standards applicable for discharge into the environment. #nuclear #antinuclear #nuclearfree #NoNukes

Fukui governor accepts utility’s nuclear fuel plan, comes under fire

THE ASAHI SHIMBUN, October 13, 2023 https://www.asahi.com/ajw/articles/15028320

FUKUI–Fukui Governor Tatsuji Sugimoto on Oct. 13 approved Kansai Electric Power Co.’s revised plan on storing spent nuclear fuel, drawing outrage from prefectural assembly members.

The governor’s approval means that three aging reactors operated by the utility in the prefecture can continue to run.

The continued operation of the old reactors was contingent on Kansai Electric finding a site outside Fukui Prefecture to store the spent fuel from its nuclear plants.

Sugimoto, who met with industry minister Yasutoshi Nishimura and Kansai Electric President Nozomu Mori on Oct. 13, approved the plan even though the utility has not picked a storage site.

“The plan is a pie in the sky as no candidate site for the interim storage facility has been presented,” a prefectural assembly member said.

Under the approved plan, operations will start at an interim storage facility outside the prefecture around 2030 for spent nuclear fuel accumulating at Kansai Electric’s nuclear power plants in Fukui Prefecture.

The spent fuel will remain there until it can be transferred to a reprocessing plant.

But that brings up another problem.

The central government has long been promoting a nuclear fuel recycling program that reprocesses spent nuclear fuel.

However, the reprocessing plant in the village of Rokkasho in Aomori Prefecture, the key facility in the recycling program, has suffered a series of problems, and its completion has been delayed for more than 25 years.

Spent nuclear fuel is currently placed in storage pools at the nuclear plants in Fukui Prefecture.

The prefectural government has been urging Kansai Electric to build an interim storage facility outside the prefecture because space is running out for the fuel.

The utility had promised to find a candidate site for the storage facility by the end of this year.

It said if it could not find a site, it would halt the No. 1 and No. 2 reactors at the Takahama nuclear plant and the No. 3 reactor at the Mihama nuclear plant. These three reactors have each been in operation for more than 40 years.

In June, Kansai Electric presented a plan to ship about 200 tons of spent nuclear fuel from the Takahama nuclear power plant to France, claiming “we fulfilled our promise.”

But the prefectural government opposed this plan, saying that volume was only a fraction of the total amount.

On Oct. 10, the utility proposed a revised plan, including increasing the amount to be shipped to France and setting up dry storage facilities within the compounds of nuclear plants in Fukui Prefecture that are separate from the existing storage pools.

Kansai Electric also said the storage capacity within the nuclear plants would not increase, in principle.

Another prefectural assembly member criticized this plan.

“Since no duration was specified for the dry storage facilities, they might end up effectively serving as the final disposal site,” the assembly member said.

Fukushima Up Close, 13 Years Later

After thirteen years, the declaration of a State of Emergency for Fukushima Daiichi Nuclear Power Plant still cannot be lifted because of many unknowns, as well as ubiquitous deadly radiation levels.

The spent fuel rods at the Fukushima nuclear reactor site are stored in pools of water on the top floor of compromised reactor buildings 100 feet above ground level……… “Continual storage in spent fuel pools is the most unsafe thing you could do.”

Fukushima Daichi Nuclear Power Plant will remain a high-risk explosive scenario for decades ahead.

CounterPunch BY ROBERT HUNZIKER 13 Oct 23

The world is turning to nuclear power as a solution to global warming, but it is postulated herein that it is a huge mistake that endangers society. One nuclear meltdown causes as much damage over the long-term as a major war. Moreover, according to Dr. Paul Dorfman, chair of the Nuclear Consulting Group, former secretary to the UK Scientific Advisory Committee on Internal Radiation: “It’s important to understand that nuclear is very likely to be a significant climate casualty.”

Also, of interest: France’s Global Warming Predicament discusses nuclear energy’s vulnerability in a global warming world.

Beyond Nuclear International recently published an article about the status of Fukushima as well as an exposé of how the nuclear industry gets away with responsibility for radiation-caused (1) deaths (2) chronic conditions like cancer (3) genetic deformities: A Strategy of Concealment, September 24, 2023, by Kolin Kobayashi, who is a Tokyo-born France-based anti-nuclear activist journalist also serving as president of Echo-Exchange. Kobayashi’s work was posted by CounterPunch under the title: How Agencies That Promote Nuclear Power Are Quietly Managing Its Disaster Narrative.

The following synopsis, including editorial license that adds important death details which defy the nuclear industry’s bogus claims about nuclear safety, opens closed pathways to what’s really going on.

After thirteen years, the declaration of a State of Emergency for Fukushima Daiichi Nuclear Power Plant still cannot be lifted because of many unknowns, as well as ubiquitous deadly radiation levels. The destroyed reactors are tinderboxes of highly radioactive spent fuel rods that contain more cesium-137 than eighty-five (85) Chernobyls. Cesium-137 in or near a human body erupts into a series of maladies, one after another in short order, depending upon level of exposure: (1) nausea (2) vomiting (3) diarrhea (4) bleeding (5) coma leading to death.

The spent fuel rods at the Fukushima nuclear reactor site are stored in pools of water on the top floor of compromised reactor buildings 100 feet above ground level, except for Unit 3 which completed removal of its spent fuel rods in 2019, an extremely slow, laborious process that’s highly dangerous.

Stored spent fuel rods in open pools of water are the epitome of high-risk. “If the 440 tonne vessel collapses, it could hit the storage pool next to it. If this pool is damaged, even partially, another major disaster could occur.” (Kobayashi) In that regard, there’s significant risk of collapse in the event of a strong earthquake. And Japan is one of the most earthquake prone countries in the world. “The city (Tokyo) government’s experts reckon there is a 70% chance of a magnitude 7, or higher, quake hitting the capital within the next 30 years.” (Source: Japan is Preparing for a Massive Earthquake, The Economist, August 31, 2023)

If exposed to open air, spent fuel rods erupt into a sizzling zirconium fire followed by massive radiation bursts of the most toxic material on the planet. It can upend an entire countryside and force evacuation of major cities. According to the widely recognized nuclear expert Paul Blanch: “Continual storage in spent fuel pools is the most unsafe thing you could do.” Paul Blanch, registered professional engineer, US Navy Reactor Operator & Instructor with 55 years of experience with nuclear engineering and regulatory agencies, is widely recognized as one of America’s leading experts on nuclear power.

Fukushima Daichi Nuclear Power Plant will remain a high-risk explosive scenario for decades ahead. After all, a program for future decommissioning is unclear and overall radiation guesstimates are formidable. All the structures where decommissioning will take place are highly radioactive and as such nearly impossible for the dangers to worker exposure.

TEPCO (Tokyo Electric Power Company) does not yet know the true extent of damage nor the complete dispersion of corium (molten magma from melted nuclear fuel rods in the core of the reactors). ……………………………………………………………………………..

Radiation Risks to Society

According to the World Nuclear Association, there were no fatalities due to radiation exposure at Fukushima. And as recently as 2021, Forbes magazine reported No one Died From Radiation At Fukushima: IAEA Boss. It is believed this is a lie and part of a massive coverup.

a lie and part of a massive coverup.

According to Green Cross (founded in 1993 by Mikhail Gorbachev, who repeatedly spoke out about interrelated threats humanity and our Earth confront from nuclear arms, chemical weapons, unsustainable development, and the human-induced decimation of the planet’s ecology): “Approximately 32 million people in Japan are affected by the radioactive fallout from the nuclear disaster in Fukushima… This includes people who were exposed to radiation and other stress factors resulting from the accident and who are consequently at potential risk from both long and short-term consequences… As with the Chernobyl nuclear accident, which impacted 10 million people, Japan is expected to see increased cancer risk and neuropsychological long-term health consequences.”

With nuclear radiation, the damage to humans shows up years later as cancer and/or deformity of newborns second/third generation. For example, only recently, the truth has come to surface about Chernobyl-related deaths, child deformities, and cancer 30+ years after the event. ………………………………………………………………

According to an article in USA Today d/d February 24, 2022, What Happened at Chernobyl? What to Know About Nuclear Disaster: “At least 28 people were killed by the disaster, but thousands more have died from cancer as a result of radiation that spread after the explosion and fire. The effects of radiation on the environment and humans is still being studied.”

According to Chernobyl Children International, 6,000 newborns are born every year in Ukraine with congenital heart defects called “Chernobyl Heart.”

…………………………………. The Fukushima Report was prepared under the direction of Prof. Jonathan M. Samet, Director of the Institute for Global Health at the University of Southern California (USC), as a Green Cross initiative. Green Cross International: GCI is an independent non-profit and nongovernmental organization founded in 1993 by Nobel Peace Laureate Mikhail Gorbachev.

Over time, Japan is expected to see increased cancer risks and neuropsychological long-term health consequences. “The lives of approximately 42 million people have been permanently affected by radioactive contamination caused by the accidents in the Chernobyl and Fukushima Daiichi nuclear power plants. Continued exposure to low-level radiation, entering the human body on a daily basis through food intake, is of particular consequence,”

Fukushima Deaths

The cocksure pro-nuclear crowd has trumpeted Fukushima as an example of Mother Nature taking lives because of an earthquake and tsunami; whereas the power plant accident proves nuclear power can withstand the worst without unnecessary death and illness. According to nuclear industry reports, all the deaths (16,000) were the fault of Mother Nature, not radiation.

But people in the streets and on the ground in Japan tell a different story about the risks of radiation. They talk about illnesses and death. TEPCO itself has reported few radiation illnesses and no radiation-caused deaths but what if it’s not their responsibility in the first instance, as layers of contractors and subcontractors employ workers to cleanup the toxic mess. If “subcontractor workers die” from radiation exposure, so what? It’s not TEPCO’s responsibility to report worker deaths of subcontractors, and the subcontractors are not motivated to report deaths, which are not reported.

According to credible sources in Japan, death is in the air, to wit: “The ashes of half a dozen unidentified laborers ended up at a Buddhist temple in this town just north of the crippled Fukushima nuclear plant. Some of the dead men had no papers, others left no emergency contacts. Their names could not be confirmed, and no family members had been tracked down to claim their remains. They were simply labeled ‘decontamination troops’ — unknown soldiers in Japan’s massive cleanup campaign to make Fukushima livable again five years after radiation poisoned the fertile countryside… Hideaki Kinoshita, a Buddhist monk… keeps the unidentified laborers’ ashes at his temple, in wooden boxes and wrapped in white cloth.” (Source: Mari Yamaguchi, Fukushima ‘Decontamination Troops’ Often Exploited, Shunned, AP & ABC News, Minamisoma, Japan, Mar 10, 2016)

……………………………………………………………………………………….Alas, two hundred U.S. sailors of the USS Ronald Reagan filed a lawsuit against TEPCO, claiming that they experienced leukemia, ulcers, gall bladder removals, brain cancer, brain tumors, testicular cancer, dysfunctional uterine bleeding, thyroid illness, stomach ailments and other complaints extremely unusual in such young adults. One sailor died from radiation complications. Among the plaintiffs was a sailor who was pregnant during the mission. Her baby was born with multiple genetic mutations.

The sailors that filed the suit participated in “Operation Tomodachi,” providing humanitarian relief after the March 11th, 2011 Fukushima disaster based upon assurances that radiation levels were okay. But that was a lie.

Ultimately, and unsurprisingly, the 9^th U.S. Circuit Court of Appeals rejected the sailors’ appeal.

In summation, the final word is left to Kolin Kobaryashi: “The international nuclear lobby, which represents only a minority, has the influence and money to dominate the world’s population with immense power and has now united the world’s minority nuclear community into one big galaxy.

Many of the citizens who have experienced the world’s three most serious civil nuclear accidents have clearly realized that nuclear energy is too dangerous. These citizens are so divided and conflicted that they feel like a helpless minority.”…………………….

Repeated malfunctions reveal safety issues in Fukushima discharge

CGTN 6 Oct 23 #nuclear #antinuclear #nuclear-free #NoNukes

Japan started the second discharge of nuclear-contaminated wastewater from the crippled Fukushima Daiichi Nuclear Power Plant into the Pacific Ocean on Thursday, despite strong opposition from local fishermen as well as neighboring and Pacific island countries.

The plant’s operator, Tokyo Electric Power Company (TEPCO), said it plans to carry out the release over 17 days to discharge 7,800 tons of the radioactive wastewater, about the same amount as the first discharge which ended on September 11.

Currently, more than 1.3 million tons of nuclear-contaminated wastewater has been accumulated in storage tanks at Fukushima.

The company’s key facility for nuclear-contaminated water treatment, the Advanced Liquid Processing System (ALPS), is a multi-filter system that can remove radioactive materials through a series of chemical reactions. The international community has had doubts about the safety, effectiveness and sustainability of the system, due to its treatment capacity and incidents of malfunction.

When the amount of nuclear-contaminated water is too large, the chances to replace the filters are limited and the performance of the ALPS is significantly degraded, said Ryota Koyama, a professor at Fukushima University in Japan.

“If nuclear-contaminated water is discharged, I think there must be a problem. If the Japanese government or the TEPCO really wants to discharge the contaminated water into the sea, they need to explain in more detail,” Koyama told China Media Group (CMG) in an interview……………………………..

The ALPS has failed to remove isotopes adequately, with the adsorbents used to remove radioactive isotopes being replaced less often than they were supposed to be. As a result, 70 percent of the water in the storage tanks still contains non-tritium radionuclides at a concentration that exceeds the regulatory standards applicable for discharge into the environment.

Since its trial operation in 2013, the ALPS has frequently experienced malfunctions. Just before the first discharge in August, TEPCO found leaks in a hose used to transfer nuclear-contaminated water, according to Japanese broadcaster NHK………………..

In June, the government of Republic of Korea said that there have been eight confirmed cases of malfunction with the ALPS between 2013 and 2022, which concerned corrosion of facilities and issues with filters, after its experts conducted an on-site inspection, said the country’s public broadcaster KBS.

According to previous reports, TEPCO found that there were at least 10 breakages on the ALPS’ filters used to absorb nuclides in August 2021. In the process of replacing the broken filters, the company discovered that 24 filters were damaged. A month later, TEPCO announced that five more filters in the ALPS were found to have been damaged, and radioactive contamination had been detected near some of the filters.

Hikaru Amano, senior researcher of the Nuclear Science Research Institute, Japan Atomic Energy Agency, told CMG that another problem with the ALPS is that there is little room to store used filters.

Amid concerns of Japan’s discharge of nuclear-contaminated wastewater, the Republic of Korea (ROK) plans to raise the number of testing spots to nearly 250 next year, increasing from the 75 coastal locations where emergency radiation tests were conducted about a month ahead of Japan’s first release in August, Seoul-based Yonhap News reported…………… https://news.cgtn.com/news/2023-10-06/Repeated-malfunctions-reveal-safety-issues-in-Fukushima-discharge-1nFOJHDPdgQ/index.html

As Japan releases more Fukushima water, what about the rest of the plant?

A second batch of treated water is being released into the Pacific, but the entire decommissioning process will be far more complex.

all that will need to take place in an environment where the level of radiation is so high, it is nearly impossible for workers to get inside.

Japan has not yet worked out where all the waste will go

Aljazeera, By Hanako Montgomery, 5 Oct 2023 #nuclear #anti-nuclear #nuclear-free #NoNukes

“…………………………………………………………………………………………Japan has promised to decommission the power station as part of its recovery plan for Namie town and the rest of Fukushima prefecture. The plant’s six reactors suffered catastrophic damage, after the tsunami smashed into the complex, crippling the plant’s cooling systems. As radioactive material leaked from the site, 470,000 people were forced to evacuate.

But while the plant had been rendered useless, progress towards its decommissioning has been slow.

Complex challenge

According to Tokyo Electric Power Company (TEPCO), the plant operator, that is partly because of the accumulation of 1.3 billion tonnes of treated radioactive wastewater that was used to cool the three reactors that were in operation at the time of the disaster.

The 1,000 or so blue and white tanks to store the water have taken up space needed for decommissioning, according to TEPCO, which has had to contend with strong criticism from local fishing communities and neighbouring countries like China, which have continued to protest against Japan’s plan to discharge the water into the ocean.

………………………………………………………………… According to TEPCO, the entire decommissioning process will take between 30 and 40 years. That is at least six times longer than it typically takes to decommission a plant under normal circumstances, Brent Heuser, a nuclear engineering professor from the University of Illinois in the United States, told Al Jazeera.

“Decommissioning involves removing fuel stored in structured arrangements. Japan, however, is facing unique challenges such as widely dispersed fuel, requiring both human and robotic efforts for detection,” he told Al Jazeera.

Japan has not yet worked out where all the waste will go.

TEPCO is planning to reduce some of it through incineration or recycling onsite, but that does not include the waste that will be produced from the dismantling of reactor buildings, and there is no estimate for how much radioactive waste there will be as the process moves forward.

To decommission the Daiichi plant, TEPCO must first remove the spent fuel and the fuel debris that is stuck inside the damaged units. Experts will then place the collected debris in storage containers before they can transport it to a new facility that will be built onsite.

The reactor buildings must also be dismantled.

Later this year, TEPCO will carry out a trial removal of melted debris from Unit 2. The retrieval will be expanded in stages if successful.

By 2027, plant operators hope to be able to turn their attention to Unit 1, the most seriously damaged of the reactors, which they plan to enclose with a large cover.

By 2031, they will focus on removing the melted debris.

But all that will need to take place in an environment where the level of radiation is so high, it is nearly impossible for workers to get inside.

“The doses they would receive would go way beyond any allowable limit, so that certainly is playing a role in the extended timeline for the decommission process,” Heuser said, suggesting more staff may be needed given the short period of time they will be able to remain on site.

“They’re spreading the worker dose exposure over a much larger body of people.”

Help from robots

The level of radiation means Japan is also yet to understand the full extent of the damage inside the corroded reactors.

TEPCO has used robotic probes to try and get a sense of the destruction. Equipped with 3D scanners, sensors, and cameras, robots have mapped the terrain, measured radiation levels, and searched for the elusive missing fuel.

Although some headway has been made in assessing the condition of the reactors, the data is far from reassuring.

Since 2022, TEPCO has dispatched a robotic probe into Unit 1.

The probe’s findings revealed the core had largely melted and settled at the bottom of the containment chamber – which serves as a vital safeguard against the release of radioactive material – and possibly Unit 1’s concrete basement. Furthermore, it suggested significant damage to the pedestal, the primary support structure directly beneath Unit 1’s core.

Financial considerations also loom large in Japan’s struggle with decommissioning

Ordinarily, the decommissioning of a standard nuclear plant would cost between $300m to $400m, according to the US nuclear regulator.

But given the extensive damage, compensation paid to local residents and the specialised equipment required for managing one of the world’s worst nuclear disasters, the Japanese government predicts the final bill could come to about 21.5 trillion yen ($141bn).

Akira Ono, who leads TEPCO’s decommissioning unit, has admitted the work is “challenging”. Earlier this year, a remotely-operated vehicle managed to collect only a tiny sample from Unit 1’s reactor, which is thought to contain some 880 tonnes of melted fuel debris -10 times the amount removed during the cleanup of Three Mile Island in the northeastern United States in 1979………………………………………………………………………….. https://www.aljazeera.com/news/2023/10/5/as-japan-releases-fukushima-water-into-the-sea-what-about-everything-else

Abstract

High doses of ionizing radiation can cause cardiovascular diseases (CVDs); however, the effects of <100 mGy radiation on CVD remain underreported. Endothelial cells (ECs) play major roles in cardiovascular health and disease, and their function is reduced by stimuli such as chronic disease, metabolic disorders, and smoking. However, whether exposure to low-dose radiation results in the disruption of similar molecular mechanisms in ECs under diabetic and non-diabetic states remains largely unknown; we aimed to address this gap in knowledge through the molecular and functional characterization of primary human aortic endothelial cells (HAECs) derived from patients with type 2 diabetes (T2D-HAECs) and normal HAECs in response to low-dose radiation. To address these limitations, we performed RNA sequencing on HAECs and T2D-HAECs following exposure to 100 mGy of ionizing radiation and examined the transcriptome changes associated with the low-dose radiation. Compared with that in the non-irradiation group, low-dose irradiation induced 243 differentially expressed genes (DEGs) (133 down-regulated and 110 up-regulated) in HAECs and 378 DEGs (195 down-regulated and 183 up-regulated) in T2D-HAECs. We also discovered a significant association between the DEGs and the interferon (IFN)-I signaling pathway, which is associated with CVD by Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analysis, protein–protein network analysis, and module analysis. Our findings demonstrate the potential impact of low-dose radiation on EC functions that are related to the risk of CVD.

Fukushima Study Links Low-Dose Radiation to Diabetes

Mirage, 3 Oct 23

New research to be presented at this year’s Annual Meeting of The European Association for the Study of Diabetes (EASD), Hamburg (2-6 Oct), suggests that exposure to low doses of radiation may contribute to an increased risk of diabetes.

The study by Dr Huan Hu and Dr Toshiteru Ohkubo from the Japanese National Institute of Occupational Safety and Health involved more than 6,000 out of around 20,000 emergency workers who responded to the radiation accident at the Fukushima Daiichi Nuclear Power Plant, which was hit by a huge tsunami in March 2011.

Substantial amounts of radioactive materials were released into the environment following explosions at the nuclear plant.

In 2014, the Epidemiological Study of Health Effects in Fukushima Emergency Workers (NEWS) was established to clarify the long-term health effects of radiation among emergency workers.

Few human studies have examined the impact of radiation exposure on diabetes development, particularly at low doses. To find out more, researchers examined the association between low-dose radiation exposure and risk of diabetes in 5,326 male emergency workers (average age 46 years) taking part in the NEWS study.

Between March and December 2011, individual emergency worker’s radiation exposure was measured using a pocket alarm dosemeter for external exposure and a whole-body counter for internal exposure.

Study participants underwent regular health examinations involving more than 70 components, including blood sugar, lipids, urine tests, inflammation biomarkers, thyroid function tests, and eye examinations.

Between 2012 and 2021, 392 participants developed diabetes—defined as a fast plasma glucose level of at least 126 mg/dL, an HbA1c level of at least 6.5%, or self-reported diagnosis of diabetes.

The researchers assessed the association between incident diabetes and cumulative radiation exposure after adjusting for a wide range of potential confounders including age, body mass index, smoking, alcohol consumption, leisure-time physical activity, employment at the nuclear power plant, dyslipidaemia (abnormally high levels of fats in the blood), and high blood pressure.

The analysis found that compared with the lowest cumulative low-dose radiation exposure (0-4 millisieverts [mSv]), the risk of developing diabetes was 6% higher for workers exposed to 5-9 mSv, and 47% and 33% greater for those exposed to 10-19 mSv and 20-49 mSv, respectively.

However, no elevated risk was detected in those exposed to radiation doses of 50 mSv or higher, likely due to the small sample size in this group.

“Our findings suggest an increased risk of diabetes among nuclear emergency workers from low levels of radiation. While the potential mechanisms remain somewhat unclear, reports suggest that radiation can adversely affect pancreatic cells responsible for insulin production, potentially contributing to diabetes. Additionally, there is an association between radiation exposure and heightened inflammation, a well-known factor in insulin resistance and the development of diabetes”, explains lead author Dr Hu.

He adds, “Ongoing follow-up of NEWS participants will provide an even clearer picture of diabetes risk at low radiation doses. As more diabetes cases emerge within our study group, our expanded dataset will enable more robust analyses, allowing researchers to better assess the link between radiation exposure and diabetes risk.”……………………………………………………………………………………………………….. more https://www.miragenews.com/fukushima-study-links-low-dose-radiation-to-1095852/
