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

 Tritium is what makes nuclear reactors so dangerous, not only in Fukushima but also in S. Korea

 Tritium is what makes nuclear reactors so dangerous, not only in Fukushima but also in S. Korea,  http://english.hani.co.kr/arti/english_edition/e_editorial/967441.html     By Kim Eun-hyoung, editorial writer, Oct.27,2020
Tritium, or hydrogen-3, is identified by the scientific symbol 3H or T. As an isotype of hydrogen, the lightest of all elements, tritium contains two neutrons, whereas ordinary hydrogen (known as protium, identified by the symbol H) contains none. That makes tritium unstable and, as a result, radioactive.

Tritium exists in the natural world, but only in negligible amounts. It’s typically produced during the fission process inside nuclear reactors. Tritium is part of the coolant that lowers the temperature in the reactor core, which is heated by fission.

The contaminated water at the Fukushima reactor that the Japanese government seeks to release into the ocean contains tritium at levels that are 10 times higher than levels permitted by the South Korean government. That has terrified people not only in Japan but also in Korea.

The Japanese government says that the contaminated water doesn’t present a problem because it will be decontaminated through Tokyo Electric Power Company’s advanced liquid processing system (ALPS), before release. But the tricky part about releasing the contaminated water is tritium, which can’t be removed by ALPS because of the strong chemical bond it forms with water.

But Fukushima isn’t the only place affected by the risk of tritium. Heavy-water reactors are cooled with heavy water (deuterium oxide, 2H2O) instead of ordinary drinking water, producing a greater amount of tritium. There are four heavy-water reactors at Korea’s Wolsong plant, including Wolsong-1, which has been in the news recently after government auditors questioned a report about its economic viability, the justification given for shutting the reactor down earlier than planned.

Tritium is regarded as a low-risk radioactive substance, causing less harm than other types of radiation. For one thing, the radiation emitted by tritium is so weak that it can’t penetrate the outer layer of the skin. And even when it is absorbed by the body, its biological half-life — the time required for half the substance to leave the body — is only 12 days.

Even now, Wolsong-2, Wolsong-3, and Wolsong-4 account for 40% of the tritium released by all of Korea’s nuclear stations. Rates of thyroid cancer among women who live near the Wolsong nuclear plant are 2.5 times higher than in other areas, which some think is linked to tritium contamination. The question of nuclear power safety affects Korea in the same way as it affects Japan. It would be foolish and contradictory to view Japanese nuclear plants through the lens of safety and Korean nuclear plants through the lens of economic viability.

But such safety observations only apply to a single dose of radiation, such as an X-ray, and the actual risk depends on the intensity of exposure. That has led various countries to develop strict safety standards for the substance. The European Committee on Radiation Risk warns that internal radiation exposure can cause mutations that could lead to cancer.

Japan’s net zero emissions target should be combined with zero nuclear power

Japan’s net zero emissions target should be combined with zero nuclear power, October 28, 2020 (Mainichi Japan)   ”……………  Under Japan’s basic energy plan, the country aims to raise the ratio of renewables to 22 to 24% by fiscal 2030. But this target is far from sufficient. As the government is currently working on a revision to the plan, it should drastically review the energy mix.

It is imperative to reconsider the nuclear power ratio said to account for 20-22% of Japan’s power mix. The government is aspiring to secure constant nuclear power output by replacing aging nuclear power stations and through other measures while moving ahead with reactivation of idled nuclear plants.

However, nuclear power complexes carry the risk of severe accidents. As it costs enormous money to secure safety at those facilities, the idea of labeling nuclear power as cheap energy is not globally accepted. The government has a responsibility to provide a road map for breaking Japan’s dependence on nuclear power.

In European countries, efforts to revive their economies severely hit by the novel coronavirus pandemic through environmental investment are underway. This initiative, called “green recovery,” can come into line with the principle of a “virtuous cycle of environment and economic growth” emphasized by Prime Minister Suga.

It is hoped that Japan will achieve a decarbonized society through improvement of renewable energy technologies and active investments in research and development of hydrogen energy and retrieval and storage of carbon dioxide.

It is also necessary to build a mechanism to guarantee the realization of the promise of net zero greenhouse gas emissions. In addition to discussions on a carbon tax, levied in accordance with the volumes of greenhouse gas emissions, the government is urged to consider specifying this goal in Japan’s Act on Promotion of Global Warming Countermeasures.

Hurdles for attaining the goal remain high and we have a limited time frame. It is urgently needed to craft a strategy to prevent the net zero target from ending up as a mere empty promise. https://mainichi.jp/english/articles/20201028/p2a/00m/0na/017000c

Aomori wants reassurance that it won’t be final nuclear waste site



Aomori Gov. Shingo Mimura (left) and Chief Cabinet Secretary Katsunobu Kato (right) attend a meeting of a council for nuclear fuel cycle policy held at the Prime Minister’s Office Wednesday.

Oct 21, 2020

Aomori Prefecture on Wednesday urged the government to reconfirm its policy of not building in the prefecture a facility for the final disposal of high-level radioactive waste from nuclear power plants across the nation.

The request was made during a meeting of a council for discussions on issues related to the country’s nuclear fuel cycle policy between relevant Cabinet ministers and officials of the prefecture, where a spent nuclear fuel reprocessing facility is under construction. It was the first meeting of the council since November 2010.

At the day’s meeting, the Aomori side called on Prime Minister Yoshihide Suga’s Cabinet, launched last month, to maintain the promise not to make the prefecture a final disposal site, upheld by past administrations.

Participants in the meeting, held at the Prime Minister’s Office in Tokyo, included Chief Cabinet Secretary Katsunobu Kato and industry minister Hiroshi Kajiyama from the central government, and Aomori Gov. Shingo Mimura.

“It’s necessary for the state and the operator (of the reprocessing plant) to make the utmost efforts to promote, with support from Aomori, the nuclear fuel cycle policy, including the launch of the plant,” Kato said at the start of the meeting.

Mimura told reporters after the meeting that he asked the central government to abide by the promise and promote the nuclear fuel cycle policy, in which uranium and plutonium are extracted from spent fuel and reprocessed into fuel for use at nuclear power plants.

Mimura indicated that Kato showed the state’s understanding of his requests.

In July, the central government’s Nuclear Regulation Authority concluded that the basic design of the nuclear fuel reprocessing plant in the Aomori village of Rokkasho meets the country’s nuclear safety standards, which were crafted after the March 2011 accident at Tokyo Electric Power Company Holdings Inc.’s tsunami-stricken Fukushima No. 1 nuclear plant.

Japan Nuclear Fuel Ltd. aims to complete the plant in fiscal 2022. The NRA spent over six years screening the Rokkasho facility’s design.

Following the NRA’s conclusion, the Aomori side asked the state to hold a meeting of the nuclear fuel cycle policy council.

Aomori has agreed to accept spent nuclear fuel from nuclear plants across the country on the condition that a final disposal facility is not constructed in the prefecture.

The central government regards the nuclear fuel cycle as a pillar of its nuclear energy strategy.

Besides the reprocessing plant, a facility to make mixed oxide, or MOX, fuel from extracted uranium and plutonium is also under construction at the same site in Rokkasho.

495 local assemblies demand Japan government ratify the Treaty on the Prohibition of Nuclear Weapons

495 local assemblies demand Japan gov’t ratify nuclear ban treaty in written statement,  October 24, 2020 Mainichi Japan  
HIROSHIMA — Over a quarter of local assemblies across Japan have adopted a written statement demanding that the central government sign and ratify the Treaty on the Prohibition of Nuclear Weapons (TPNW), a report by the Japan Council against Atomic and Hydrogen Bombs (Gensuikyo) revealed. ……

The nuclear arms prohibition treaty was adopted in July 2017 by 122 countries and regions — over 60% of the United Nation’s membership. The treaty bans the development, test, manufacture, possession or use of atomic weapons, as well as the threat of their use — the basis of nuclear deterrent. Japan did not participate in negotiations nor signed the pact, along with the five nuclear powers of the United States, Russia, Britain, France and China. Tokyo stayed out of the pact for fear of appearing to denounce nuclear deterrence and thereby deepening conflict between nuclear have and have-not nations.

In response, Gensuikyo decided in a global conference held in Hiroshima and Nagasaki in August 2017 that it will approach local assemblies in Japan to adopt written statements asking the national government to sign and ratify the nuclear ban treaty. Atomic bomb survivors have been engaged in these efforts across Japan.

According to Gensuikyo, the prefectural assemblies of Iwate, Nagano, Mie, Tottori, and Okinawa, as well as 490 municipal assemblies — 28% of all local assemblies nationwide — had adopted the written statement as of Oct. 23, 2020. The tally includes assemblies that have adopted the objective of the written statement, as they agree with it but are uncertain of its feasibility. A total of 34 assemblies in Iwate, including the prefectural assembly, adopted the statement. The statement was initially turned down twice in the municipal assembly of Ofunato, Iwate Prefecture, but finally gathered a majority in March 2020 after Gensuikyo explained persistently about damage resulting from nuclear weapons.

Meanwhile, no local assemblies in the prefectures of Toyama, Fukui, Yamaguchi and Saga have adopted the statement.
A tendency among conservative assembly members to dislike passing written statements that counter central government policy has apparently led to the regional differences. Even in the atomic bomb-stricken areas of Hiroshima and Nagasaki prefectures, the statement’s adoption rate is 67% and 32%, respectively.

Sixteen municipal assemblies in Hiroshima Prefecture, including the Hiroshima city assembly, have adopted the statement, with authorities saying, “Our country, the only nation that has experienced atomic bombing, has a special role and responsibility to strive to abolish nuclear weapons.” However, Hiroshima Prefectural Assembly lawmakers did not even submit a proposal to adopt the statement.

Fumikazu Furuta, secretariat head at Gensuikyo’s Hiroshima branch, explained that a prefectural assembly member belonging to the ruling Liberal Democratic Party rejected his request for cooperation by saying, “We must consider the views of party headquarters.”

There are also local assemblies that reject adopting the statement as it is not legally binding, and by claiming that national defense and security are exclusively under central government jurisdiction. Soji Kanno, deputy secretariat head at Gensuikyo’s Iwate branch, who approached Iwate Prefecture assemblies with the statement, commented, “Abolishing nuclear weapons is not a political request, but the wish of the Japanese public. I’d like for all local assemblies to raise their voices towards the Japanese government.”

Angry reactions to Japanese government’s plan to release Fukushima nuclearwaste water into the Pacific

Plan to release Fukushima water into Pacific provokes furious reaction   https://www.dw.com/en/tepco-fukushima-contaminated-water/a-55334567 25 Oct 20, The Japanese government has reportedly decided to pump highly radioactive cooling water from the Fukushima plant into the Pacific Ocean. The plan has been slammed by environmental groups, locals and neighboring nations.Environmental groups have reacted furiously to reports that the Japanese government is set to approve plans to dump more than 1 million tons of highly radioactive water stored at the Fukushima nuclear plant into the Pacific Ocean, with their concerns shared by the governments of neighboring countries and people living in northeastern Japan.

A government panel set up to determine the best way of disposing the radioactively contaminated water is scheduled to announce its decision by the end of the month.

Three Fukushima reactors suffered meltdowns following a 2011 tsunami that destroyed wide swaths of the coastline in northern Japan’s Miyagi prefecture.

According to reports leaked to Japanese media, the panel will recommend releasing the approximately 1.23 million tons of water currently stored in tanks in the grounds of the nuclear plant.

The alternatives that have been considered are to evaporate the water into the atmosphere or to mix it into concrete and store it underground.

According to reports from national broadcaster NHK and other news outlets, the panel will call for the water to be again put through a process designed to reduce the radioactivity to below “regulatory standards” and dilute it with sea water before it is pumped into the ocean.

The three damaged reactors require constant cooling with water, which becomes highly radioactive, and mixes with around 170 tons of groundwater that seeps into the subterranean levels of the reactor buildings every day.

That water is pumped into hundreds of huge tanks on the site every day, with Tokyo Electric Power Co. (Tepco), the operator of the power plant, estimating that even with more waste tanks being constructed, storage capacity will be reached fully in the summer of 2022.

Environmental groups insist that there is no reason why more storage tanks cannot be constructed outside the perimeter of the plant. They accuse the government of seeking the cheapest and quickest solution to the problem, as authorities have promised the site will be safe in 40 years.

And that deadline, they say, is completely unrealistic. Complications include recovering the molten fuel that escaped from the reactor chambers. This kind of recovery has never before been attempted and the technology required does not yet exist.

They also accuse the Japanese authorities of playing down the radiation levels in the water planned for release.

Environmental groups insist that there is no reason why more storage tanks cannot be constructed outside the perimeter of the plant. They accuse the government of seeking the cheapest and quickest solution to the problem, as authorities have promised the site will be safe in 40 years.

And that deadline, they say, is completely unrealistic. Complications include recovering the molten fuel that escaped from the reactor chambers. This kind of recovery has never before been attempted and the technology required does not yet exist.

They also accuse the Japanese authorities of playing down the radiation levels in the water planned for release.

Elevated levels of radiation

A study by the Kahoko Shinpo newspaper confirmed that levels of iodine 129 and ruthenium 106 exceeded acceptable levels in 45 out of 84 samples collected in 2017.

Iodine has a half-life of 15.7 million years and can cause cancer of the thyroid, while ruthenium 106 is produced by nuclear fission and high doses can be toxic or carcinogenic when ingested.

Tepco subsequently confirmed that levels of strontium 90 were more than 100 times above legally permitted levels in nearly 65,000 tons of water that had already been treated,

They were 20,000 times above safety levels set by the government in several storage tanks at the Fukushima site.

Fish industry worried

Precisely what is in the water that is due to be released into the ocean cannot be confirmed, however, as Tepco and the government have refused to permit independent testing on samples.

Residents of Fukushima Prefecture are also against the plan, with 42 of the 59 local authorities in the prefecture passing resolutions either expressing outright opposition to the plan or deep concern.

The fishing industry — which was devastated by the original natural disaster and has since struggled to reestablish itself — is also hostile to the proposals, with representatives of fishing cooperatives meeting with government officials last week to express their concerns.

“We are terrified that if even one fish is found to have exceeded the [radiation] safety standards after the treated water is released, people’s trust in us will plummet,” a fisherman from the city of Soma told Kyodo News. “Our efforts to fight false information and address other challenges could be wasted.”

Hideyuki Ban, co-director of the Citizens Nuclear Information Center, echoed those calls.

“Release of the contaminated water into the ocean should not be allowed when fishing unions from Fukushima and neighboring Ibaraki and Iwate prefectures are opposed,” he told DW.

“If it is dumped in the ocean, it will become an international problem and it is possible that bans on exports from this area will continue or that new export restrictions may be introduced.”

“It is highly unlikely that the highly radioactive waste can be removed from the site of the nuclear plant, so instead of rushing to remove the fuel debris, the overall decommissioning schedule should be reviewed and measures taken so that the contaminated water can be stored on land,” he said.

In a statement issued to DW, Tepco said it is “not in a position to make a decision on this matter.”

“The government has been listening to the opinions of various stakeholders, including local municipalities and those involved in the agriculture, forestry and fisheries industries, and it is the government that will make a decision on the disposal method,” the company said, adding Tepco will follow the disposal guidelines as instructed following the official decision.

Neighbors’ concerns

The residents of Japan’s neighboring countries and their governments are equally concerned, with an editorial in the Korea Times on Monday warning of an “environmental disaster” that could “destroy the marine ecosystem.”

The South Korean government has also demanded that Japan provide a full accounting of its plans for the contaminated water, including an accurate accounting of the different radionuclides that it contains.

In a statement released by the Foreign Ministry, Seoul said it places the highest priority on protecting the environment and the Korean public’s health.

Scientists and academics in China are demanding independent testing and verification of radiation levels in the water, while environmental and citizens’ groups in Taiwan have previously expressed concerns about the impact of any large-scale release of contaminated water on their health and well-being.

Hokkaido municipalities gamble on a nuclear future, but at what cost?  

Hokkaido municipalities gamble on a nuclear future, but at what cost?    https://www.japantimes.co.jp/news/2020/10/24/national/media-national/hokkaido-gambling-casinos/  BY PHILIP BRASOR   Since August, two local governments on the western shore of Hokkaido have said they will apply to the central government for a survey that could eventually lead to their municipalities hosting a permanent underground repository for high-level radioactive waste. The fact that these two localities made their announcements about a month apart and are situated not far from each other was enough to attract more than the usual media attention, which revealed not only the straitened financial situations of the two areas, but also the muddled official policy regarding waste produced by the country’s nuclear power plants.

The respective populations of the two municipalities reacted differently. The town of Suttsu made its announcement in August, or, at least, its 71-year-old mayor did, apparently without first gaining the understanding of his constituents, who, according to various media, are opposed to the plan. An Oct. 8 Tokyo Broadcasting System Television news report said that someone threw a molotov cocktail in the vicinity of the mayor’s house the previous evening, and an Oct. 13 Tokyo Shimbun article said the mayor’s announcement came after he received a petition demanding the town not apply for the survey.
Meanwhile, the mayor of the village of Kamoenai says he also wants to apply for the study after the local chamber of commerce urged the village assembly to do so in early September. TBS asked residents about the matter and they seemed genuinely in favor of the study because of the village’s fiscal situation. Traditionally, the area gets by on fishing — namely, herring and salmon — which has been in decline for years. A local government whose application for the survey is approved will receive up to ¥2 billion in subsidies from the central government.
 This money was probably the reason for the Suttsu mayor’s interest, too, but, according to Tokyo Shimbun, the population of Suttsu is generally younger and they may be afraid of what a survey for the purpose of building a nuclear waste repository would mean for their future. Kamoenai, on the other hand, is already receiving subsidies for nuclear-related matters. The village is 10 kilometers from the Tomari nuclear power plant, where some residents of Kamoenai work. In exchange for allowing the construction of the plant, the village now receives about ¥80 million a year, a sum that accounts for 15 percent of its budget. According to TBS, Kamoenai increasingly relies on that money as time goes by, since its population has declined by more than half over the past 40 years.
It’s possible for both municipalities to be approved for the survey, though that hardly seems guaranteed. Since Japan’s Nuclear Waste Management Organization started soliciting local governments for possible waste storage sites in 2002, a few localities have expressed interest, but only one — the town of Toyo in Kochi Prefecture — has actually applied, and then the residents elected a new mayor who canceled the application. The residents’ concern was understandable: The waste in question can remain radioactive for up to 100,000 years.
However, the selection process also takes a long time. The first phase survey, which uses existing data to study geological attributes of the given area, requires about two years. If all parties agree to continue, the second phase survey, in which geological samples are taken, takes up to four years. The final survey phase, in which a makeshift underground facility is built, takes around 14 years. And that’s all before construction of the actual repository begins
Some people in Suttsu suspect that the mayor will simply grab the subsidy money and then quit after the first phase, but, according to a lawyer interviewed by Tokyo Shimbun, it’s not that easy. Following the first phase, the Nuclear Waste Management Organization decides if the municipality is eligible for the second phase, which comes with a ¥7 billion payout, and, in principle, the head of the municipality as well as the governor of the surrounding prefecture are given “consideration” as to whether they want to proceed. Hokkaido’s governor, Naomichi Suzuki, has already said he is opposed to the applications, but there seems to be nothing in the law that prevents the Nuclear Waste Management Organization from going ahead regardless of what he or other locals think.

Then again, neither Suttsu nor Kamoenai may make it past the first stage. Yugo Ono, an honorary geology professor at Hokkaido University, told the magazine Aera that Suttsu is located relatively close to a convergence of faults that caused a major earthquake in 2018. And Kamoenai is already considered inappropriate for a repository on a map drawn up by the trade ministry in 2017.

If the Nuclear Waste Management Organization’s process for selecting a site sounds arbitrary, it could reflect the government’s general attitude toward future plans for nuclear power, which is still considered national policy, despite the fact that only three reactors nationwide are online. Presently, spent fuel is being stored in cooling pools at 17 nuclear plants comprising a storage capacity of 21,400 tons. As of March, 75 percent of that capacity was being used, so there is still some time to find a final resting place for the waste. Some of this spent fuel was supposed to be recycled at the Rokkasho Reprocessing Plant in Aomori Prefecture, but, due to numerous setbacks, it doesn’t look as if it’s ever going to open, so the fuel will just become hazardous garbage.

Ono tells Aera that the individual private nuclear plants should, in line with product liability laws, be required to manage their own waste themselves. If they don’t have the capacity, then they should create more. It’s wrong to bury the waste 300 meters underground, which is the plan, because many things can happen over the course of future millennia. The waste should be in a safe place on the surface, where it can be readily monitored.

However, that would require lots of money virtually forever, something the government would prefer not to think about, much less explain. Instead, they’ve made plans that allow them to kick the can down the road for as long as possible.

Warnings on releasing Fukushima’s radioactive water into the Pacific Ocean

Warning over Fukushima nuclear power plant water release, 7 News,  CNN,  Allie Godfrey,  Sunday, 25 October 2020 Contaminated water that could soon be released into the sea from the Fukushima Daiichi nuclear power plant contains radioactive carbon with the potential to damage human DNA, environmental rights organisation Greenpeace has warned.

The environmental group claims that the 1.23 million metric tons of water stored at the plant – scene of the 2011 Fukushima Daiichi nuclear disaster – contains “dangerous” levels of the radioactive isotope carbon-14 and other “hazardous” radionuclides, which it says will have “serious long-term consequences for communities and the environment” if the water is released into the Pacific Ocean.

To cool fuel cores at the damaged Fukushima nuclear plant operator Tokyo Electric Power Company (TEPCO) has pumped in tens of thousands of tons of water over the years. Once used, the water is put into storage.

But nine years on from Japan’s worst nuclear disaster, storage space is running out, and the government is still deciding what to do with the water.

Authorities, including the country’s environment minister, have indicated the only solution is to release it into the ocean – a plan facing opposition from environmental campaigners and fishing industry representatives.

On Friday, the Japanese government postponed a decision on what to do with the water. ……….“Any radioactive discharge carries some environmental and health risk,” Francis Livens, a professor of radiochemistry at the University of Manchester told CNN, adding that the risk would be relative to how much carbon 14 would be released into the ocean. “An awful lot really does depend on how much is going to be discharged.”

“If it’s (carbon-14) there and it’s there in quantity, yes, there probably is a risk associated with it,” Livens, who is not associated with the Greenpeace study, said. “People have discharged carbon-14 into the sea over many years. It all comes down to how much is there, how much is dispersed, does it enter marine food chains and find its way back to people?”……..

Corkhill told CNN the contaminated water is becoming a pressing concern: If the Japanese government does not deal with the contaminated water, it will have “several millions of cubic meters of water that’s radioactive all sat on the Fukushima site,” she said. https://7news.com.au/technology/warning-over-fukushima-nuclear-power-plant-water-release-c-1453141

Japan now has enough plutonium to make about 6,000 atomic bombs

Japan Sticks to Nuclear Fuel Recycling Plan Despite Plutonium Stockpile

Japan now has 45.5 tons of separated plutonium, enough to make about 6,000 atomic bombs.  https://thediplomat.com/2020/10/japan-sticks-to-nuclear-fuel-recycling-plan-despite-plutonium-stockpile/

By Mari Yamaguchi, October 21, 2020   Japan’s government said Wednesday it will pursue a nuclear fuel recycling program that would involve extracting plutonium from spent fuel, despite international concerns about the country’s already huge plutonium stockpile and lack of prospects for effectively consuming it as nuclear fuel.

Chief Cabinet Secretary Kato Katsunobu, at a meeting with the governor of Aomori prefecture, home to Japan’s pending nuclear fuel reprocessing plant, reaffirmed that new Prime Minister Suga Yoshihide’s government will pursue the country’s nuclear energy policy.

“The government will firmly promote our nuclear energy policy and fuel cycle programs,” Kato said. He said Japan will make effort to reduce volume and toxicity of high-level nuclear waste, and extract plutonium from spent fuel from a resource conservation point of view.

critics say continuation of spent fuel reprocessing only adds to Japan’s already large plutonium stockpile. Japan also lacks a final repository for high-level nuclear waste.

Wednesday’s meeting came after the Nuclear Regulation Authority granted a safety approval this past summer for the Rokkasho fuel reprocessing plant, operated by Japan Nuclear Fuel Ltd., located in northern Japan, for a planned launch in 2022. The authority also gave a preliminary permit for the Rokkasho MOX fuel production plant, also planned for completion in 2022.

Japan now has 45.5 tons of separated plutonium — 8.9 tons at home, and 36.6 tons in Britain and France, where spent fuel from Japanese nuclear plants has been reprocessed and stored because Japan lacks a plant to produce MOX fuel containing plutonium at home. The amount is enough to make about 6,000 atomic bombs.

Despite security concerns raised by Washington and others, the stockpile is hardly decreasing due to difficulties in achieving a full nuclear fuel recycling program and slow restarts of reactors amid setbacks from the 2011 Fukushima disaster.

Japan reprocesses spent fuel, instead of disposing it as waste, to extract plutonium and uranium to make MOX fuel for reuse, while the U.S. discontinued the costly and challenging program. Allowed under international safeguard rules, Japan is the only non-nuclear weapons state that separates plutonium for peaceful purposes, though the same technology can make atomic bombs.

Taiwan furthers its departure from nuclear power, with more unused fuel rods sent back to USA

More fuel rods at fourth nuclear power plant sent back to U.S. https://focustaiwan.tw/society/202010210027

(By Flor Wang and Wang Chao-yu)  10/21/2020 Taipei, Oct. 21 (CNA) More fuel rods at a mothballed nuclear power plant in New Taipei were shipped back to the United States on Wednesday as part of government to honor its promise to make Taiwan nuclear-free by 2025.efforts

Five or six trucks carrying an unknown number of unused fuel rods from the Fourth Nuclear Power Plant arrived at Keelung Port in the early hours and were then loaded into several containers that departed for the U.S. at around noon.

However, the authorities in charge did not disclose whether this is the last batch of fuel rods being sent back to America.

A Legislative Yuan resolution that was passed in 2018 demands that state-run Taiwan Power Co. (Taipower) must send back all 1,744 unused fuel rods from the plant to America by the end of this year.

Taipower has said the task will cost NT$700 million (US$24.1 million).

In July 2018, the first batch of 160 rods was transported back to its U.S. supplier — Global Nuclear Fuel Americas, LLC — which was followed by three more similar operations as of August 2019, the Taipei-based China Times reported on Tuesday.

On Oct. 15, Atomic Energy Council Minister Hsieh Shou-shing (謝曉星) said 240 fuel rods at the power plant were still waiting to be transported to the U.S. — a delay caused by travel restrictions triggered by the COVID-19 pandemic.

According to the Ministry of Economic Affairs, disposing of the 1,744 fuel rods from the plant could save about NT$100 million in maintenance costs per year.

The government has spent NT$283.8 billion on building the plant in New Taipei’s Gongliao District, but it has been mothballed since 2014 due to public concern over the use of nuclear power.

Japan – nuclear power fine – but no nuclear waste for Aomori Prefecture, please

Aomori wants reassurance that it won’t be final nuclear waste site, Japan Times, 21 Oct 20, Aomori Prefecture on Wednesday urged the government to reconfirm its policy of not building in the prefecture a facility for the final disposal of high-level radioactive waste from nuclear power plants across the nation.The request was made during a meeting of a council for discussions on issues related to the country’s nuclear fuel cycle policy between relevant Cabinet ministers and officials of the prefecture, where a spent nuclear fuel reprocessing facility is under construction.

Besides the reprocessing plant, a facility to make mixed oxide, or MOX, fuel from extracted uranium and plutonium is also under construction at the same site in Rokkasho. https://www.japantimes.co.jp/news/2020/10/21/national/japan-aomori-nuclear-waste-disposal/

Nuclear pollution in China – the Uighur people pay the health and environmental price

Nuclear imperialism in China’s Xinjiang, Observer Research Foundation,TARA RAO,  19 Oct 20, 

A third of the PRCs uranium for nuclear energy comes from extortion in the Yili basin of Xinjiang. This is also home to a great population of Uighurs.

Today, China has one of the world’s largest nuclear energy development programmes. During the Cold War era, there did not exist a political or economic motivator for commercialising nuclear energy as coal-fired power stations and hydroelectric energy dominated the system. However, after 2005, China has been able to reinvent this narrative. Notably, what this resurrected was a reassertion of spaces of injustice for their minorities. Their lands were first grounds for nuclear weapons’ testing and now used for energy rather than warfare purposes, thus continuing a historical subjugation to nuclear imperialism. This nuclear imperialism situates itself within an already prevalent cyclic violence against China’s far western frontier region of Xinjiang’s ethnic minorities, the predominantly Muslim Uighurs, ever since the establishment of the People’s Republic of China (PRC) in 1949.

Given the inherent differentiation between the Uighurs and the Chinese dominant ethnicity, the Hans, the former’s identity was always up for scrutiny. The government came down particularly hard on the Uighurs after the events of 9/11 initiated the Global War on Terror (GWOT), as well as the Ürümqi riots on 5 July 2009 which saw clashes between protesting Uighurs, Han people, and China’s People’s Armed Police, leaving nearly 200 people dead in Xinjiang. The Chinese government has attributed security concerns with the certain ‘terrorist’ acts committed by a handful of them. Taking what some might perceive as an opportunist stand, China was able to claim being victim to global terrorism, to justify crackdown on the minority group. What this terrorist narrative in turn ushered in was a transnational territory of uncontrolled spaces where ‘dangerous populations’ need not be afforded legal protections and therefore be made to quarantine; containing their actions that often correspond to security threats. The antagonism was not restricted to the few Uighurs rioters. Instead the entire Uighur community as a single biological group was treated as the Homo Sacer.

………….. The systematic discrimination of the Uighur feeds into a larger understanding of necro-politics of Uighur lives having become too consequential juxtaposed with a system which is ready to dispense with this minority population. The emphasis here is on China’s first nuclear weapons test in Lop Nor, and the legacy it has translated onto the present day context through states sponsored uranium mining in the Yili Basin, underscoring a new kind of imperialism.

Nuclear weapon testing began in the mid-1960s. Soon a kind of nuclear imperialism started to take root in the existing Han colonisation of Uighur spaces. The latter revolved around a combination of contestation over the sovereignty of the Uighur homeland and the resource-rich soils they inhabited. The aftermath of the Sino-Soviet split meant a collapse in PRCs nuclear relationship with China which acted as a driver for hastening and furthering their ambitious nuclear programmes. The PRC became the fifth nation to develop nuclear weapons during the Cold War. They formally established the 10,000 km sq. Lop Nor Nuclear Test base in 1956. It still stands as the largest site of its kind in the world………

Professor Jun Takada conducted a study explaining how peak levels of radioactivity from large yield tests might have had prolonged consequences in the biological makeup of the generations to come observing congenital defects and cancer incidents in some. The cancer incidents in the region were approximately 35% higher than the rest of the state. Uighur traditional medicine could not cope with these cases. In short, a biopolitical regime protected the state from liability, meanwhile for the Uighurs, contestation around state assurance and health risks posed a blurring in the causation between sickness and exposition.

The Uighurs who were affected by the Lop Nor test therefore have been given no compensation or recognition from the state. Many Hans on the other hand were given assurance from the state especially in terms of healthcare on various occasions. This only furthered the resentment and tension between the Hans and the Uighurs of Xinjiang in the years to come.

Following this, peaceful protests sprung up. In November 1985, protests led by students in Beijing against nuclear weapon tests were met with brute state coercion. In 1993, Uighurs gathered at Log Nor and demanded the ban of nuclear testing but were interrupted by PLA forces, some protestors were shot in the process. The Tigers of Lop Nor were an organisation that even managed to send tanks inside nuclear spaces and blew up planes in protest. Moreover, enveloped in this environment, the Uighur identity that already clashed with Han nationalism was simply made starker; the anti-nuclear movement began to echo separatist tendencies.

Today, a third of the PRCs uranium for nuclear energy comes from extortion in the Yili basin of Xinjiang. This is also home to a great population of Uighurs. The PRC has placed a moratorium on the manufacturing of fissile material for deterrence purposes, transforming Xinjiang into the primary hub for the nuclear energy industry. The NINT continues to partake in nuclear research, to the north of the Lop Nor test site. There is no state system in place to ensure the safety of those dwelling the Yili. What this reflects is a revival of a past narrative of nuclear imperialism as uranium energy extraction seems to have overtaken nuclear testing. There appears to be no incentive from the ends of the government; a lacking in enforceable nuclear legislations and regional systems of monitoring and regulating nuclear activity. …….

. China now possesses over 44 nuclear reactors in operation and 18 others under construction and is striving towards ensuring that 1/5th of their energy comes from their power plants by 2030. Activism from the minorities in the region is often counted by officials as acts of Islamism or cultural protests rather than a legacy of activities against the nuclear industry which is another layer of discrimination that has been recognised by the Uighurs.

More anti-nuclear activism seems to be entering the eastern provinces of Shandong, Jiangsu, and Guangdong as a result of general community concerns against an unprotected nuclear policy. Online petitions and active media are slowly entering the scene to influence and mobilise public opinion. However, it is only perhaps a matter of time before the PRC silences them too.

Censorship is often used to subdue this kind of opposition online. What is worse is that the Uighurs of Xinjiang lack the agency to voice their grievances while practitioners in the east who are often familiar with the political systems and often well-educated are able to make negotiations with the state in terms of the relocation of nuclear power plants. ……… https://www.orfonline.org/expert-speak/nuclear-imperialism-china-xinjiang/

China’s world-leading push for solar and wind energy

Renew Extra 17th Oct 2020, Renewables have been accelerating ahead in China, which is adding far more
capacity each year than any other country, with over 760GW installed so
far. By contrast, the EU has only managed 500GW, the USA 250 GW.
However, the pace of expansion in China has slowed of late. Annual onshore wind
capacity additions in China are expected to fall by over 16% to 19 GW from
2020 to 2021, given the Chinese government’s decision to end subsidies,
say analysts Wood Mackenzie.
Even so, over the next decade Wood Mac expect
250 GW of wind capacity to be added, with repowering opportunities onshore
and growth potential offshore. Indeed, some see the latter booming
dramatically. So, while wind subsidies will fall by 3.2%, wind capacity
will still grow, and PV solar seem likely to do even better: incentives for
PV will rise by 14%, with some seeing solar as the major growth area longer
term, helping China get 62% of its power from non-fossil sources by 2030.
