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

Getting the facts straight about Chernobyl, nuclear disasters, and ionising radiation

Fact check: 5 myths about the Chernobyl nuclear disaster

Monday marks the 35th anniversary of the Chernobyl nuclear disaster. What happened in the former Soviet Union on April 26, 1986, is no longer a secret.  DW, 

Is Chernobyl the biggest-ever nuclear disaster?

The 1986 nuclear disaster at the Chernobyl nuclear power plant near the city of Pripyat in northern Ukraine is often described as the worst nuclear accident in history. However, rarely is this sensational depiction clarified in more detail. 

The International Nuclear and Radiological Event Scale (INES) does classify nuclear events on a scale of zero to seven, breaking them down into accidents, incidents and anomalies. It was introduced in 1990 after being developed by the International Atomic Energy Agency (IAEA) and the Nuclear Energy Agency of the Organization for Economic Cooperation and Development (NEA/OECD). Level seven denotes a “major accident,” which means “major release of radioactive material with widespread health and environmental effects requiring implementation of planned and extended countermeasures.”

Both the Chernobyl and 2011 Fukushima disaster have been categorized as such. But INES does not allow for nuclear events to be classified within a level.

If the term nuclear disaster is not only used to describe events, or accidents, in nuclear reactors but also radioactive emissions caused by humans then there are many occasions when human-caused nuclear contamination has been greater than that of the Chernobyl disaster, explained Kate Brown, professor of science, technology and society at the Massachusetts Institute of Technology.

“Let’s take the production of plutonium,” she told DW, referring to the American and Soviet plants that produced plutonium at the center of a nuclear bomb. “Those plants each issued as part of the normal working everyday order at least 350 million curies [a unit of radioactivity — Editor’s note] into the surrounding environment. And that was not an accident.

“Let’s look at, even more dire, the issuance of radioactive fallout in the detonation of nuclear bombs during the periods of nuclear testing ground, which were located throughout the world, ” she continued. “Those just take one isotope, one radioactive iodine, which is harmful to human health because it’s taken up by the human thyroid, causing thyroid cancer or thyroid disease.

“Chernobyl issued 45 million curies of radioactive iodine just in two years of testing, in 1961 and 1962. The Soviets and the Americans issued not 45 million curies, but 20 billion curies of radioactive iodine,” she said. And these tests, she added, were by design — not due to an accident or human error.

Are there mutants in the exclusion zone?

………….. “The influence of ionizing radiation may cause some restructuring in the body, but mostly it simply reduces an organism’s viability,” he explained, giving the example of high embryo fatalities in rodents due to genomic defects that prevented the organism from functioning. Those animals that survive the womb sometimes have disabilities that prevent them from staying alive in the wild. Vishnevsky and his colleagues have conducted research into thousands of animals in the exclusion zone, but have not found any unusual morphological alterations.

“Why? Because we were always dealing with animals that had survived and had won the fight for survival,” he said. He added that it was difficult to compare these animals with creatures that scientists had deliberately exposed to radiation in laboratories.

“That’s a very seductive idea, that human messed up nature and all they have to do is step away and nature rewrites itself,” she said. In reality, however, biologists say that there are fewer species of insects, birds and mammals than before the disaster. The fact that some endangered species can be found in the exclusion zone is not evidence of the area’s health and vitality.

Has nature reclaimed the site of the disaster?

Reports entitled “Life Flourishing Around Chernobyl” and photo series suggesting that the exclusion zone has become a “natural paradise” might give the impression that nature has recovered from the nuclear disaster. But Brown, who has been researching Chernobyl for 25 years, is adamant that this is “not true.”

“That’s a very seductive idea, that human messed up nature and all they have to do is step away and nature rewrites itself,” she said. In reality, however, biologists say that there are fewer species of insects, birds and mammals than before the disaster. The fact that some endangered species can be found in the exclusion zone is not evidence of the area’s health and vitality.

On the contrary: there has been a significant increase in the mortality rate and a lowered life expectancy in the animal population, with more tumors and immune defects, disorders of the blood and circulatory system and early ageing.

Scientists have attributed the apparent natural diversity to species migration and the vastness of the area. “The exclusion zone comprises 2,600 square kilometers [about 1,000 square miles]. And to the north are another 2,000 square kilometers to the north is Belarus’ exclusion zone,” said Vishnevsky. “There are also areas to the east and west where the human population density is extremely low. We have a huge potential for preserving local wild fauna.” That includes lynxes, bears and wolves which need a great deal of space.

But even 35 years after the disaster the land is still contaminated by radiation, a third of it by transuranium elements with a half-life of more than 24,000 years.

Is it safe for tourists to visit Chernobyl?

The exclusion zone was already a magnet for disaster tourists, but in 2019 annual numbers doubled to 124,000 after the success of the HBO miniseries Chernobyl. The State Agency of Ukraine on Exclusion Zone Management has set up a number of routes so tourists can visit the region by land, water or air. It has also drawn up a number of regulations to protect visitors, stipulating that people must be covered from head to toe. They shouldn’t eat any food or drink outside, and they should always follow official paths. It’s estimated that the radiation dose received over a one-day visit does not exceed 0.1 millisievert (mSv) — roughly the same dose that a passenger would be exposed to on a long-distance flight from Germany to Japan, according to Germany’s Federal Office for Radiation

Are there people living in the area?

Today, Pripyat, the closed city built to serve the nuclear plant and house its employees, is often described as a ghost town, as is the nearby city of Chernobyl.

However, neither has been entirely empty since 1986. Thousands of people, usually men, have stayed there, often working two-week shifts and ensuring that the crucial infrastructure in both cities continues to function. After the explosion in reactor No. 4, reactors 1, 2 and 3 continued to operate, closing down only in 1991, 1996 and 2000. Special units of the Ukrainian Interior Ministry police the zone. There are also stores and at least two hotels in Chernobyl, which are mainly for business visitors.

There are also a number of unofficial inhabitants, including people who used to live in the area and have chosen to return. They have settled in villages that were evacuated after the disaster. The exact number of people is unknown: when DW asked the State Agency of Ukraine on Exclusion Zone Management how many people lived in Chernobyl, the official answer was “nobody.” 

In 2016, about 180 people were thought to be living in the entire exclusion zone. Because they tended to be older, this number may well have fallen. Even though these locals are officially only tolerated, the state does support them in their everyday lives. Their pensions are delivered once a month, and every two to three months they are supplied with food by a mobile store.   https://www.dw.com/en/fact-check-5-myths-about-the-chernobyl-nuclear-disaster/a-57314231

Remarkable new photos inside the Chernobyl nuclear power station

 PetraPixel.com, ARKADIUSZ PODNIESIŃSKI  25 Apr 21, ”/……………  The reason for my regular visits remains the same: the desire to document the changes taking place in the Chernobyl Exclusion Zone. And there’s been quite a few: from the construction of the New Safe Confinement (which I wrote about in more detail here), to the construction of several new industrial facilities that will make the decommissioning of the plant, including the damaged Reactor 4, possible and much safer. I hope that, under the influence of slow but systematic changes, eventually Chernobyl will not only be known as the site of the largest nuclear disaster in the world………

before we are allowed to enter the main part of the complex, aka the dirty zone, we have to change into protective gear and masks. We are also given a dosimeter that counts the dose of radiation absorbed. When we exit, the procedure is repeated in reverse order and so on in every complex we visit. Sometimes, the procedures take longer than our stay inside the facility.

…….. First, we got to the largest hall where there is a huge pool with more than 21,000 spent fuel assemblies from reactors 1-3. Depending on the location, radiation levels vary from 40 to 800 μSv/h, which is about 200-400 times higher than normal. The ISF-1 is a wet-type spent fuel storage facility, meaning that the fuel assemblies are stored in water. The huge pool consists of five reinforced concrete tanks covered by hundreds of steel plates.  As I step on them, I feel rather strange and insecure because I know what lies beneath them. Additionally, every step I take causes the steel flaps to move, causing a sound that echoes throughout the hall. I’m only calmed by the sight of the engineer, who confidently steps on the plates, not looking at me at all. After a moment, the engineer bends down and opens one. The radiation increases, but only slightly. The lack of a cover doesn’t change all that much; the greatest barrier against the radiation is the water.

The fuel assemblies are pulled out in the hall next door. Now I can stay here freely, but the radiation levels during this procedure are very high – about 2 Sv/h. This is already a dose that can cause serious radiation sickness or even death. Due to this, the entire process is controlled remotely through a small window made of thick leaded glass or through a system of monitors and cameras from a small room located several meters above us…..

ISF-2 – the Interim Spent Nuclear Fuel Storage Facility 2

The ISF-2 complex serves as an interim storage facility for dry-type spent fuel assemblies. Before the spent fuel goes there, it is processed first in a building located on the premises.

Inside, my attention is drawn to the “hot chamber”, the heart of the entire building. A huge, hermetically sealed room, completely isolated from the external environment by thick concrete walls; you can look inside through small leaded glass windows located on both sides of the chamber. Cameras resistant to high levels of radiation and remote-controlled machinery and tools have been installed inside. It is here that the spent fuel assemblies from the defunct reactors will be cut in half, dried, and later packed into double-layered steel canisters.

The view of the hot chamber makes me realize how dangerous a task we have before us. And a long-term one, since the radioactive isotopes in the fuel will take thousands of years to decay. 100 years, the storage period for the processed fuel in ISF-2, is just a blink of an eye for radioactive isotopes. What’s next? ISF-3? We don’t know yet…….. This is the problem we will face – well, not us but future generations.

In December 2020, the “hot tests” for the whole complex concluded. At that time, 22 containers with 186 fuel assemblies had been processed for the first time and then packed into two steel canisters and stored in concrete modules behind the main building. It is estimated that the entire fuel processing process will take about 10 years, and the complex will become the world’s largest dry spent fuel storage facility.

ICSRM – the Industrial Complex for Solid Radwaste Management

In addition to the ISF-1 and ISF-2, which deal with spent nuclear fuel, another two facilities have been built on the site for the treatment of solid and liquid radioactive waste collected from the operation and decommissioning of the power plant and from the sarcophagus.

In addition to the ISF-1 and ISF-2, which deal with spent nuclear fuel, another two facilities have been built on the site for the treatment of solid and liquid radioactive waste collected from the operation and decommissioning of the power plant and from the sarcophagus. I visit the first, where low-, intermediate- and high-level waste is processed for temporary or final storage, including concrete, sand, and metal. The huge building contains a system of airtight caissons, hot chambers, and other areas where radioactive waste is cut, fragmented, shredded, sorted by radioactivity level, compressed, and incinerated. All of the work is done using remote-controlled machines to which interchangeable tools can be attached — including a jackhammer, concrete crusher, chainsaw, and hydraulic shears. The processed waste is then encapsulated and sealed in concrete containers before being sent to a radioactive waste repository. Like the ISF-2, the plant has already processed its first batch of radioactive waste and currently is in the final stages of hot testing and certification.

New Safe Confinement

The New Safe Confinement (NSC) is a huge 110-meter-high steel construction that was built to cover the old, worn-out sarcophagus. ………………..

In this labyrinth of near-identical corridors, I quickly lose my sense of direction and, after a while, I stop paying attention to the signs. I blindly follow the dosimetrist. Although the masks prevent us from breathing in radioactive dust, there is nothing we can do to protect ourselves from the gamma radiation penetrating our bodies. Unseen dangers may lurk around every corner. In such a situation, the dosimeters are our eyes; thanks to them we know how far we can go.

The thought that I’m moving through a mysterious labyrinth of radioactive corridors covered by two sarcophagi stresses me out and increases my feelings of uncertainty and confusion. …….

The Chernobyl story continues

Chernobyl: The next phase   https://www.ebrd.com/news/2021/chernobyl-the-next-phase.html By Axel  Reiserer, 23 Apr 2021

At 01:23:40 on 26 April 1986, the failure of a routine test at the Chernobyl Nuclear Power Plant in Ukraine, then part of the Soviet Union, caused reactor 4 to explode, releasing parts of its radioactive core. It was the worst nuclear accident the world had ever seen, with far-reaching political, economic and ecological consequences. Thirty-five years on, Chernobyl is still as well-known as it was a generation ago.

Fires broke out, causing the main release of radioactivity into the environment. Wind carried contaminated particles over Ukraine, Belarus and Russia, as well as parts of Scandinavia and wider Europe. The 50,000 inhabitants of the adjacent town of Pripyat were evacuated, never to return.

The accident destroyed reactor 4, killing 30 operators and firemen within three months and causing numerous other deaths in weeks and months that followed. To this day, it remains the only accident in the history of the civil use of nuclear power when radiation-related fatalities occurred. The precise number of short- and longer-term victims remains heavily disputed.

By 06:35 on 26 April, all fires at the power plant had been extinguished, apart from the fire inside reactor 4, which continued to burn for many days. Some 5,000 tonnes of boron, dolomite, sand, clay and lead were dropped from helicopters in a bid to extinguish the blaze. When the destroyed reactor was later enclosed in a provisional structure – the so-called sarcophagus – these fuel-containing materials were also walled in.

The sarcophagus was built under extremely hazardous conditions and unprecedented time pressure. By November 1986, a steel and concrete shelter was in place to lock away the radioactive substances inside the ruined reactor building and to act as a radiation shield. It was always intended as a temporary measure, with an estimated lifespan of 20-30 years

The search for a long-term solution started soon after, alongside the massive challenge of cleaning up the accident site. By the end of 1991, the Soviet Union had dissolved and newly independent Ukraine had been left with the Chernobyl legacy. Following a G7 Action Plan to improve nuclear safety in central and eastern Europe, the Nuclear Safety Account was set up at the European Bank for Reconstruction and Development (EBRD) in 1993. Two years later, the scope of the programme was extended to include Chernobyl.

A breakthrough came with the Shelter Implementation Plan in 1997, which provided a road map of how to the tackle the immediate and longer-term tasks. In the same year, the G7 officially invited the EBRD to set up and manage the Chernobyl Shelter Fund, which became the main vehicle for all efforts to ensure that the destroyed reactor 4 remained in an environmentally safe and secure state.

Emergency repairs in 1998 and 1999 prevented the imminent collapse of the sarcophagus, as well as a vent stack that was endangering the adjacent turbine hall over reactor 3, which was still in operation. It was only at the end of 2000 that all nuclear power generation in Chernobyl ceased. The following year saw a landmark decision to build an arch-shaped steel structure, called the New Safe Confinement (NSC), to seal off reactor 4.

In the subsequent years, several tasks were carried out simultaneously. Detailed technical work on the NSC started. The site had to be stabilised and prepared for the construction work. The first project the EBRD managed was the construction of a liquid radioactive waste treatment plant (LRTP) to handle some 35,000 cubic metres of low- and intermediate-level liquid waste at the site. Meanwhile, the safe storage of the spent fuel assemblies from reactors 1, 2 and 3 came into focus.

All this has been achieved. The LRTP has been operational since 2014. A new interim storage facility for the treatment and storage of spent fuel has been built and, after successful hot tests, is currently awaiting a permanent licence from the Ukrainian regulator. The NSC, the most visible Chernobyl project, was slid into position in late 2016 and then handed over to the Ukrainian authorities.

In total, the Bank has managed close to €2 billion in donor funds through the Chernobyl Shelter Fund and Nuclear Safety Account. Of this, the EBRD provided €715 million of its own resources to complete the Interim Storage Facility and New Safe Confinement.

Today, the New Safe Confinement dominates the skyline over Chernobyl, as the sarcophagus once did. The steel structure is 108 metres high and 162 metres long, with a span of 257 metres and a lifetime of at least 100 years. It was assembled in two stages in a cleaned area near the accident site and, despite its size and weight of 36,000 tonnes, was pushed 327 metres into position. It is the largest moveable structure ever built.

This is not where the story ends, however. The fact that the NSC has a lifespan of 100 years means that the next phase of work now has to be planned, agreed and implemented. The estimated 200 tonnes of radioactive nuclear fuel inside reactor 4 are now shielded by the New Safe Confinement. However, parts of the sarcophagus are becoming unstable and will have to be removed at some point. Once this is done, work will come closer to the reactor’s interior.

The EBRD remains a key partner in these efforts. Following a request by Ukraine, in November 2020, the Bank established the new International Chernobyl Co-Operation Account, aimed at creating an integrated plan for the site to serve as the basis for developing and implementing longer-term projects. The new fund will hold it first assembly meeting on Tuesday – fittingly one day after the 35th anniversary. The Chernobyl story continues.

Decision on Fukushima waste water should be in consultation with international agencies, not just a decision by Japan alone.

Disposal of Fukushima nuclear wastewater should be assessed under framework of intl agencies, not let world pay: FM, By Global Times, 21 Apr 21, China’s Foreign Ministry said on Wednesday the disposal of Fukushima nuclear wastewater should be assessed and discussed under the framework of international agencies including the UN, the WHO, and the IAEA, urging the Japanese government to correct its irresponsible decision to dump of the wastewater to the ocean and avoid involving people all around the world in paying for its wrongdoings. 

The remarks came after South Korean Foreign Minister Chung Eui-yong expressed opposition to the move, and said on Tuesday that Seoul will work closely with international agencies to deal with Japan.

At a routine press conference, China’s Foreign Ministry spokesperson Wang Wenbin stressed that before dumping nuclear-contaminated water, there should be a discussion with neighboring countries and an evaluation within the framework of international agencies including the United Nations, the World Health Organization, and the International Atomic Energy Agency.

Wang added that Japan’s decision to dump the nuclear-contaminated water is not only opaque, unscientific, unlawful, irresponsible and unethical, but also at risk of being condemned by the world.

“A ban has been placed on black scorpionfish caught off Fukushima waters from entering markets due to the detection of excessive radioactive materials. And this is the second time that fish have been found with excessive radioactive materials in Fukushima waters since February,” said Wang.

All of these signs point to the fact that disposal of radionuclides is complicated and difficult, noted Wang, adding that the Fukushima nuclear power plant accident has been bringing harm to its surroundings for the past decade since it happened. ……..

Wang said that the methods of the wastewater disposal concern the safety of the Asia-Pacific region, the global ecological environment, and the lives and the health of people in all countries. The data should be evaluated and consultations held with all parties whose interests are bound to it.

“We noticed that Japan’s Tokyo Electric Power Company intends to submit a progress plan for wastewater disposal in May. We express strong opposition and serious concern to the matter as Japan unilaterally pushes forward the plan without consultation with the international community especially neighboring countries,” Wang said.  

“Please don’t let people all over the world pay for Japan’s wrongdoings,” he added.  https://www.globaltimes.cn/page/202104/1221712.shtml

Overdue Shutdown of the Indian Point Nuclear Plant

Overdue Shutdown of the Indian Point Nuclear Plant

Environmental groups write that gains in energy efficiency and renewable power exceed the plant’s annual output. 

“Nuclear Plant’s Shutdown Means More Fossil Fuel in New York”(news article, April 13):

New York State is making good on its promise to replace the aging, unsafe Indian Point nuclear plant with clean energy. Gains in energy efficiency and renewable power over the last decade already exceed the plant’s total annual output, with much more to come.

We can expect year-to-year changes given fluctuations in energy demand and prices. But the overall trend in New York is clear: Clean energy is here to stay, and emissions reductions are on track to reach the state’s ambitious climate goals.

Closing this dangerous plant is overdue. Over the years Indian Point has experienced reactor structure problems with the potential for structural failure, as well as leaks, fires and unplanned shutdowns.

For the 20 million people who live within 50 miles of it, Indian Point’s long-planned closure ends a risky chapter.  Paul GallayKit Kennedy

The $2.5Billion-a-year effort to stabilise the Hanford reservation’s dangerous nuclear wastes


Nuclear waste structures in Washington state are stabilized,  https://apnews.com/article/environment-and-nature-business-government-and-politics-washington-nuclear-waste-14e29e8923c62bf5835f33e1b649000c    RICHLAND, Wash. (AP) — The U.S. Department of Energy has confirmed that two underground structures at the decommissioned Hanford nuclear reservation in Washington state have been stabilized after they were deemed at risk of collapsing and spreading radioactive contamination into the air.

“With this work completed, Hanford has ensured the stability of these structures and reduced risks to workers and the environment,” department spokesperson Geoff Tyree said.

The partial collapse of a tunnel storing nuclear waste the nuclear reservation in 2017 prompted a federal study which concluded last year that a large settling tank and two trenches where plutonium-contaminated liquids were poured into the ground for disposal posed a high risk of collapse and contamination, Tri-City Herald reported Tuesday.

The Hanford reservation produced plutonium for nuclear weapons during the Cold War and World War II, leaving 56 million gallons (212 million litres) of radioactive waste in underground tanks. The largest of the three underground structures, which operated from 1955 to 1962, was estimated to be contaminated with 105 pounds (48 kilograms) of plutonium.

Scott Sax, president of Hanford contractor Central Plateau Cleanup Co., told employees that the three underground structures identified in the study were filled with concrete-like grout to prevent them from collapsing.

The work was done by White Shield Inc. of Pasco under a contract originally valued at about $4 million.

Sax also said that at least one of the trenches was buried deep enough to prevent nuclear waste from releasing into the air in the event of a collapse.

“Routine monitoring will continue to ensure all three structures remain stable,” Sax said, at least until further environmental cleanup action is taken.

Final cleanup plans for the structures have not yet been made as the Energy Department focuses on other high-priority projects, including capsules of radioactive waste that are at risk of releasing contamination in the event of a severe earthquake.

About $2.5 billion a year is being spent to stabilize and clean up waste and contamination left at the 580-square-mile (1,500-square-kilometer) site in Richland, Washington about 200 miles (322 kilometers) southeast of Seattle, officials said.

S.Korean students shave heads in protest over Japan’s nuclear waste water plan


S.Korean students shave heads in protest over Japan’s nuclear waste water plan, Reuters, Hyun Yi  21 Apr 21, More than 30 South Korean college students shaved their heads in front of the Japanese embassy in Seoul on Tuesday to protest Japan’s decision to release water from its crippled Fukushima nuclear plant into the sea.

Police periodically dispersed crowds, who chanted and held placards, but did not stop the event from taking place, though there is an anti-pandemic ban on gatherings larger than 10 people.

The protesters who were shaved were draped in protective sheets emblazoned with messages condemning the Japanese plan and calling for it to be ditched.

One read: “The Japanese government should immediately cancel the plan to release the contaminated water.”…….. https://www.reuters.com/business/environment/skorean-students-shave-heads-protest-over-japans-nuclear-waste-water-plan-2021-04-20/

The danger of Japan dumping Fukushima wastewater into the ocean

The danger of Japan dumping Fukushima wastewater into the ocean, https://thehill.com/opinion/energy-environment/548726-the-danger-of-japan-dumping-fukushima-wastewater-into-the-ocean

BY RICK STEINER,— 04/17/21  The Japanese government just announced that it intends to release over 1.2 million tons of radioactive wastewater from the Fukushima Nuclear Power Plant into the North Pacific. This would result in dangerous radionuclides flowing across the ocean to Russia, Alaska, Canada, Hawaii and the U.S. West Coast. The release of this material — which is strongly opposed by local scientists and residents in Japan — would begin in two years and continue for another 40 years.

The Biden administration must urge Japan to abandon this unnecessary and dangerous plan.

The 2011 Fukushima nuclear disaster was caused by the 9.1 magnitude Tohoku earthquake and a 14-meter-high tsunami. The tsunami flooded and disabled emergency generators needed to pump cooling water into the nuclear reactor cores, causing three reactor core meltdowns and hydrogen explosions. Radionuclides flowed eastward across the Pacific and were eventually found in waters off California, Hawaii, Oregon, Washington, British Columbia  and Alaska. We all live downstream. 

The storage tanks now hold seawater that has been used to continue cooling the reactor cores, and this water is contaminated with such radionuclides as Cesium-137, Carbon-14, tritium (including the more dangerous “Organically Bound Tritium”), Strontium-90, Cobalt-60, Iodine-129, Plutonium-239 — and over 50 other radionuclides. Some of this has reportedly been removed, but some has not (e.g. radioactive tritium and C-14).  

The Tokyo Electric Power Company (TEPCO) that owns Fukushima, and is now responsible for the cleanup (that is likely to last the remainder of this century), didn’t admit until recently that the wastewater contains significant amounts of radioactive Carbon-14. As C-14 has a half-life of 5,730 years, and is known to bio-accumulate in marine ecosystems and cause cellular and genetic impairment. This is a very serious concern.

Fukushima C-14 will be added to the already elevated radioactive C-14 load in the oceans from nuclear weapons tests — or  “bomb carbon” — last century. It’s now found in organisms even in the deepest part of the ocean, the Marianas Trench. It is easy to imagine the impact this new, intentional Fukushima release could have, rightly or not, on the public image of clean marine seafood and tourism along the Pacific coast.

TEPCO claims the water has been sufficiently treated and is OK to release, but the treatment system they are using is reported to be substandard and not up to the job. Communities across the Pacific deserve an independent scientific assessment of TEPCO’s claims, by an Independent Scientific and Technical Commission. Remember, TEPCO and the Japanese government approved locating the nuclear power plant’s emergency generators in a tsunami flood zone. Their assurances now that there is no risk in releasing this radioactive water are neither credible nor scientifically defensible.

China and South Korea have registered objections to the release plan with Japan, but other downstream nations — the U.S., Russia and Canada — have stayed quiet. It isn’t often that China expresses more concern for the environment than the U.S., but this is one such time.

And even if the ecological and public health risk from the planned release is indeed low, as claimed (this is highly doubtful), the risk is entirely unnecessary and avoidable. 

Beyond marine discharge, several other disposal options have been considered, including evaporating the water, or injecting it into deep geologic formations.

But by far the best solution is for TEPCO to build more storage tanks and continue holding all contaminated water for another 15 years or so, during which time the radioactive tritium level will decay by half, and simultaneously treat it with best available technology (such as ion exchange systems and modular “detritiation” systems in the U.S.) to remove all radionuclides possible. 

Japan and TEPCO considered this long-term storage option, but opted instead for the cheapest choice — simply dumping the wastewater into the Pacific. 

The era of intentionally dumping toxic waste in our one global ocean is, or should be, over.

Fukushima was, and continues to be, a nuclear nightmare, and all nations should join together in a collaborative effort to resolve this mess. This effort will take hundreds of billions of dollars, over many decades, and the U.S. and other G20 nations must step up and help both financially and technically.

Unless and until this wastewater is independently certified as effectively free of radionuclides and safe, not one drop should be released into the beautiful deep blue Pacific.

Finally, Fukushima should be the last nail in the coffin for the notion that nuclear fission power could be a realistic solution to our climate crisis.

In Ontario, opponents of nuclear waste disposal join forces 

Opponents of nuclear waste disposal join forces  https://www.tbnewswatch.com/local-news/opponents-of-nuclear-waste-disposal-join-forces-3644864 ‘Ignace should not get to decide’ whether to accept a storage site, a spokesperson says.

By: Gary Rinne   19 Apr 21, KENORA, Ont. — Thirty thousand households and businesses in Northwestern Ontario are receiving postcards from a group of organizations opposed to nuclear waste disposal in Northwestern Ontario.

We the Nuclear Free North calls itself an alliance of Indigenous and non-Indigenous volunteers and organizations who believe the risks of transporting and burying nuclear waste are too high.

It’s delivering information cards outlining its concerns to residents living between Upsala and the Manitoba border.

The Nuclear Waste Management Organization has identified the Revell Lake area, about 35 kilometres from Ignace, as a candidate site for an underground repository, and is continuing to conduct studies in the area.

NWMO is also still looking at a site in Bruce County in southern Ontario.

We the Nuclear Free North says it has launched a website to provide information about the project from sources that are independent of the nuclear power companies that generate and own Canada’s nuclear waste. 

It says NWMO is proposing to send multiple truckloads of highly radioactive waste to its selected site “every day for at least 40 years.”

Spokesperson Fred Melanson, who served on Ear Falls council when that community was being studied for nuclear waste disposal, said “This is not the kind of development the people of Northwestern Ontario want. Burying nuclear waste is a high-risk experiment.”

Although NWMO has developed a working relationship with the Township of Ignace during the study process, Environment North representative Dodie LeGassick said “This is not an issue for one community. It is an issue for the entire region.”

LeGassick said “Ignace should not get to decide whether 22,000 trucks hauling radioactive waste drive through Nipigon and through Shuniah Township and all of the other many communities along the route.”

On its website, the alliance – which includes Environment North and Northwatch – also notes that the United Nations Declaration on the Rights of Indigenous Peoples requires that states “take effective measures to ensure that no storage or disposal of hazardous materials shall take place in the lands or territories of indigenous peoples without their free, prior and informed consent.”  

Peter White, an elder with Grand Council Treaty # 3’s Ki’ieshgitabaaning Cultural and Healing Lodge said “The lives of our children and future generations are too precious to be used as a nuclear experiment and should not have this burden put on their shoulders.”

NWMO intends to make a final decision on the location of the underground storage site in 2023.

U.N. experts concerned at Japan’s decision to dump Fukushima nuclear waste-water into the Paific.

UN Experts Decry Japan’s Plan to Dump Radioactive Fukushima Wastewater Into Ocean, https://www.commondreams.org/news/2021/04/16/un-experts-decry-japans-plan-dump-radioactive-fukushima-wastewater-ocean?utm_campaign=shareaholic&utm_medium=Social&utm_source=facebook&fbclid=IwAR2W9TNN5pZWTgQjFhnnd_99e_F3cH4y7uPJggM1row-iqAzbRtoZvj2tvM

The decision is particularly disappointing as experts believe alternative solutions to the problem are available,” said the three special rapporteurs.by Brett Wilkins, staff writer  18 Apr 21, A trio of United Nations experts on Thursday added their voices to the chorus of concern over the Japanese government’s decision to dump hundreds of millions of gallons of radioactive wastewater from the Fukushima Daiichi Nuclear Power Plant into the Pacific Ocean, saying the move threatens not only the environment but also the human rights of people in and beyond Japan.

Japanese officials announced earlier this week that 1.25 million tonnes of treated radioactive water from the deactivated nuclear plant—which in March 2011 suffered major damage from a magnitude 9.0 earthquake and subsequent tsunami—would be discharged into the sea starting in about two years. Prime Minister Suga Yoshihide called the planned release “a realistic solution.” 

However, anti-nuclear campaigners joined Japan’s neighbors China and South Korea in condemning the decision, with Greenpeace saying that it “completely disregards the human rights and interests of the people in Fukushima, wider Japan, and the Asia-Pacific region.”

Marcos Orellana, Michael Fakhri, and David Boyd—respectively the U.N.’s special rapporteurs on toxics and human rights, the right to food, and human rights and the environment—weighed in on the issue Thursday with a joint statement calling Tokyo’s decision “very concerning.”

“The release of one million tonnes of contaminated water into the marine environment imposes considerable risks to the full enjoyment of human rights of concerned populations in and beyond the borders of Japan,” they said, adding that “the decision is particularly disappointing as experts believe alternative solutions to the problem are available.”

Critics say other options for disposing of the the water, including evaporating and then releasing it into the air, were not fully considered, although nuclear experts stress that evaporation would not isolate radioactivity. 

Japanese officials claim that levels of radioactive tritium are low enough to pose no threat to human health. However, scientists and other experts warn that the isotope bonds with other molecules in water and can make their way up the food chain to humans.

Cindy Folkers, radiation and health hazards specialist at the advocacy group Beyond Nuclear, said in a statement Wednesday that Fukushima Daiichi operator Tokyo Electric Power Company (TEPCO) “wants us to believe that the radioactive contamination in this water will be diluted in the ocean waters, but some of the radioactive isotopes will concentrate up the food chain in ocean life.”

“Some of the contamination may not travel out to sea and can double back on itself,” said Folkers. “Dilution doesn’t work for radioactive isotopes, particularly tritium, which research shows can travel upstream.”

“TEPCO data show that even twice-through filtration leaves the water 13.7 times more concentrated with hazardous tritium—radioactive hydrogen—than Japan’s allowable standard for ocean dumping, and about one million times higher than the concentration of natural tritium in Earth’s surface waters,” she added. 

Japanese officials did reverse one highly controversial policy related to the wastewater dump this week. Amid intense public backlash, the government hastily retired Little Mr. Tritium, an animated radioactive mascot meant to promote and popularize the discharge.

“It seems the government’s desire to release the water into the sea takes priority over everything,” Katsuo Watanabe, an 82-year-old fisher from Fukushima, told Kyodo News. “We fisherman can’t understand it.”

PNM Resources to replace its Palo Verde nuclear energy with 100% solar and battery


Sierra Club 16th April 2021, After announcing it would drop one of its leases in the Palo Verde Nuclear plant last year, this month PNM proposed replacing the energy with 100% solar and battery. In support of its proposal, PNM cited the Energy Transition Act’s requirements and the Public Regulation Commission’s decision last year to choose a 100% solar/storage proposalrather PNM’s favored gas-inclusive replacement scenario for San Juan Generating Station coal. The replacement proposal will need to be approved by the commission. In selecting carbon emission-free generation to replace Palo Verde, PNM states in testimony it has taken into
consideration “the state’s energy transition policies and long-term mandate for a carbon emission-free generation portfolio.” While we have yet to delve into all of the details of PNM’s application, this is very
encouraging and we look forward to supporting PNM’s request for prompt approval of replacement resources.

A new plan for disposing of nuclear waste at USA’s Waste Isolation Pilot Plant

Carlsbad Current Argus 14th April 2021, A plan to build two new areas to dispose of nuclear waste began taking
shape at the Waste Isolation Pilot Plant after the U.S. Department of Energy published a report on the feasibility of adding an 11th and 12th waste panel to the underground nuclear waste repository.

At WIPP, low-level transuranic (TRU) waste made up of equipment and materials radiated during nuclear activities is permanently emplaced in an underground salt deposit more than 2,000 feet underground. In its original design, WIPP was planned to have eight panels for such disposal, but much of that space wasrestricted and abandoned following an accidental radiological release in2014 that contaminated parts of the underground and led to a three-year
pause of WIPP’s emplacement operations.

Nuclear power combined with nuclear weapons – confronts Britain with an intractable problem.

Electrical Review 14th April 2021, Nuclear waste has been an intractable problem ever since nuclear power was
developed over 60 years ago. It has become a very expensive and politically embarrassing issue all around the world.

Not that the Johnson Government would admit this. Many in it still argue that nuclear power is the answer
to climate change, conveniently forgetting that they are passing the waste buck onto future generations. To those in power, the solution to the waste problem is always just around the corner, to be resolved just beyond their term of office.

But the history of nuclear over the last six decades, across the globe, is of dozens of failed schemes. Currently the UK is
undertaking its sixth search in 42 years for a nuclear waste dump site. Yet again wrestling with the problem of years of public consultations, planning inquiries and geological investigations, only to be finally rejected, even as scientists warn that continued neglect of the issue is placing citizens in increasing danger.

The problem is that civil nuclear industries, especially when, as in Britain, they are combined with a weapons programme, produce plutonium and other by-products in spent fuel that take as long as 100,000 years to decay. International law requires the country that produced the waste to dispose of it within its own boundaries. Identifying
somewhere to put this waste, where they could be safe for that length of time, requires stable geological formations that are very hard to find anywhere.

Nuclear power’s waste problem complicates it as a green energy solution

The US Energy Department’s renewed promotion of plutonium-fueled reactors. 

Plutonium programs in East Asia and Idaho will challenge the Biden administration, Bulletin of the Atomic Scientists, By Frank N. von Hippel | April 12, 2021  ”’…………. The US Energy Department’s renewed promotion of plutonium-fueled reactors. The US plutonium breeder reactor development program was ended by Congress in 1983. A decade later, the Clinton Administration shut down the Idaho National Laboratory’s Experimental Breeder Reactor II for lack of mission. At the time, I was working in the White House and supported that decision.

The nuclear-energy divisions at the Energy Department’s Argonne and Idaho National Laboratories refused to give up, however. They continued to produce articles promoting sodium-cooled reactors and laboratory studies on “pyroprocessing,” a small-scale technology used to separate plutonium from the fuel of the Experimental Breeder Reactor II .

During the Trump administration, this low-level effort broke out. With the Energy Department’s Office of Nuclear Energy headed by a former Idaho National Lab staffer and help from Idaho’s two Senators, the Energy Department and Congress were persuaded to approve the first steps toward construction at the Idaho National Laboratory of a larger version of the decommissioned Experimental Breeder Reactor II.

 The new reactor, misleadingly labeled the “Versatile Test Reactor,” would be built by Bechtel with design support by GE-Hitachi and Bill Gates’ Terrapower. The Energy Department awarded contracts to the Battelle Energy Alliance and to university nuclear-engineering departments in Indiana, Massachusetts, Michigan, and Oregon to develop proposals for how to use the Versatile Test Reactor.

The current estimated cost of the Versatile Test Reactor is $2.6-5.8 billion, and it is to be fueled with plutonium. The Idaho National Laboratory’s hope is to convince Congress to commit to funding its construction in 2021.

The Energy Department also committed $80 million to co-fund the construction of a 345-megawatt-electric (MWe) “Natrium” (Latin for sodium) demonstration liquid-sodium-cooled power reactor proposed by GE-Hitachi and Terrapower which it hopes Congress would increase to $1.6 billion. It also committed $25 million each to Advanced Reactor Concepts and General Atomics to design small sodium-cooled reactors. And it has subsidized Oklo, a $25-million startup company financed by the Koch family, to construct a 1.5 MWe “microreactor” on the Idaho National Laboratory’s site to demonstrate an extravagantly costly power source for remote regions.


In all these reactors, the chain reaction would be sustained by fast neutrons unlike the slow neutrons that sustain the chain reactions in water-cooled reactors. The Energy Department’s Office of Nuclear Energy has justified the need for the Versatile Test Reactor by the fast-neutron reactors whose construction it is supporting. In this way, it has “bootstraping” the Versatile Test Reactor by creating a need for it that would not otherwise exist.

This program also is undermining US nonproliferation policy..………..https://thebulletin.org/2021/04/plutonium-programs-in-east-asia-and-idaho-will-challenge-the-biden-administration/?utm_source=Newsletter&utm_medium=Email&utm_campaign=MondayNewsletter04122021&utm_content=NuclearRisk_EastAsia_04122021
