Chernobyl-area Fires Spread Radiation Spewed by 1986 Disaster…Again

“Minor increases in radiation” — IAEA

Editor’s note: The International Atomic Energy Agency (IAEA) is the UN’s nuclear reactor agency, and was established to promote the nuclear power industry. IAEA’s purpose, announced in its charter, says it “shall seek to accelerate and enlarge the contribution of atomic energy… throughout the world” and to “encourage…atomic energy for peaceful uses throughout the world.”  Often identified as a “watchdog agency,” IAEA is a fully captured arm of the nuclear power lobby. IAEA’s announcements routinely understate, or minimize the extent and the dangerousness of radiation releases, as well as the risks of radiation exposures.

Dangerously increased levels of radiation in breathable radioactive particles lofted and windblown by April wildfires in and around the Chernobyl reactor disaster exclusion zone were reported April 13 by Kiev officials.

Dangerously increased levels of radiation in breathable radioactive particles lofted and windblown by April wildfires in and around the Chernobyl reactor disaster exclusion zone—which was permanently contaminated in April 1986 by one of the world’s worst radiation catastrophes—–were reported April 13 by Kiev officials.

The BBC and Reuters reported April 13 that acting head of Ukraine’s state ecological inspection service, Yegor Firsov, said in an April 5 Facebook post that radiation levels in the area had risen substantially above normal.

“There is bad news. In the center of the fire, radiation is above normal,” Firsov said, posting a video of a Geiger counter. “As you can see in the video, the readings of the device are 2.3, when the norm is 0.14. But this is only within the area of the fire outbreak,” the UPI reported April 6. The reading was more than 16 times normal.

However, “Government officials later rejected this finding, and said the levels in the area were ‘within normal limits,’” and “Mr Firsov also withdrew his remarks,” the BBC said.

In short order Ukrainian government agencies and the IAEA went to work assuring the public that the radiation-tainted forest fire smoke was not a danger to people in Ukraine.

In an April 24 press release the IAEA said, “The burning of meadows, pastures and stubble has resulted in some minor increases in radiation due to the release of radionuclides transferred from soil contaminated in the 1986 accident. But the concentration of radioactive materials in the air remained below Ukraine’s radiation safety norms and posed no public health concern, the SNRIU said,” referring to the Ukraine’s State Nuclear Regulatory Inspectorate of Ukraine.

“These fires happen almost every year”

Radio Free Europe reported April 26 that “Ukrainian officials have attributed smoky air in Kiev in recent days to fires in the nearby Zhytomyr region, assuring residents that radiation levels in the Ukrainian capital are within an acceptable range.”

“Background radiation in [Kiev] is ‘stable’ and does ‘not exceed the permissible values,’ [Ukraine’s] State Emergency Service said on April 26,” the 34th anniversary of the catastrophic explosions and fires caused by Chernobyl’s reactor 4, Radio Free Europe said.

Greenpeace Russia reported April 23 that “plumes of smoke caused smog in [Kiev], 250 kilometers away and although they did not exceed norms, higher levels of radioactivity than usual were detected.”

NBC News reported April 18 that Volodymyr Demchuk, director of the Emergency Response Department, said in a video statement, “The radioactive background in Kiev and the Kiev region is within normal limits.”

Official assurances of “normal limits”, and “permissible” or “acceptable” levels of radiation exposure studiously avoid saying that exposure to or inhaling radiation is “safe.” Further, the IAEA and the Ukrainian authorities neglect any mention of particular isotopes in the air, what sorts of radiation was being emitted, where the radioactive particles might settle, the length of time the particles persist in the environment, and the risks posed by radioactive “daughter” elements left for decades by the radioactive decay process.

“Forest fires in contaminated areas are a big problem for Ukraine, Belarus, and Russia where five million people still live in contaminated areas according to official data. These fires happen almost every year,” reported Greenpeace Russia’s nuclear campaigner Rashid Alimov.

Japan’s Failed Water Filtration System Praised by IAEA

By John LaForge
Nukewatch Quarterly Summer 2020

An official review by the International Atomic Energy Agency (IAEA) of Japan’s efforts to manage nearly 1,000 million gallons of radioactive wastewater at Fukushima says that a team of its experts “welcomed progress” made by Japan on choosing how to dispose of 1.37 million cubic meters of radioactive wastewater left from cooling the extremely hot mounds of melted uranium fuel cores under the three melted and exploded nuclear reactors.

The IAEA reported on April 2, 2020 that, “Contaminated water from the Fukushima Daiichi Nuclear Power Station is treated through a process known as Advanced Liquid Processing System (ALPS) to remove radionuclides except tritium and then store it on site.”*

The IAEA went as far as to declare that “The ALPS multi-nuclide removal system continues to operate stably and reliably.”

Remarkably, the glowing report on Japan’s efforts ignored the spectacular and widely-reported failure of ALPS to separate deadly radioactive isotopes other than tritium on August 18, 2018.**

Vast quantities of highly radioactive particles were not caught by the ALPS and are now stored in giant tanks on the coastal Fukushima-Daiichi site. This coastline is still subject to regular and potentially severe earthquakes that could see the tanks ruptured and on-site workers and the Pacific Ocean highly contaminated in the event of another quake.

The gross failure of the ALPS is reportedly being addressed by “re-filtering” the highly contaminated wastewater through the same system, but this “do over” by the on-site operators is not mentioned by the IAEA expert panel.

The report notes instead that, “With the volume of ALPS-treated water expected to reach the planned tank capacity of approximately 1.37 million m3 around the summer of 2022, and taking into account that further treatment … would be needed for implementation of any of the solutions considered by the Government of Japan, a decision on the disposition path should be taken urgently engaging all stakeholders.” The panel also said, “The IAEA Review Team also notes that the ALPS-treated water will be further purified as necessary to meet the regulatory standards for discharge before dilution.”

The panel’s “specific advisory point one” is that, “The injected water used to cool the fuel debris mixes with ingressed water and contributes to the generation of contaminated water.”

The phrase “ingressed water” is a veiled reference to the tons of ground water steadily pouring into the wrecked reactor buildings through earthquake-caused cracks in foundations, broken pipes, and smashed ductwork. This groundwater also floods the melted masses of uranium fuel and becomes highly contaminated.

Tepco (operator of the Fukushima reactor), the Japanese government and the IAEA want to dump the vast volume of radioactive wastewater into the ocean.

The Japan Times reported March 25 that the company has drafted a plan to spend 20 to 30 years draining the large tanks into the Pacific.

Any dumping would add the wastewater’s extremely long-lived radioactive materials, to that already poured into the Pacific by the 2011 disaster, and the nine continuous years of the sites releasing between 200 and 400 tons per day of contaminated water.

Radioactive materials littering the ocean and the ocean floor can be consumed by sea life where the isotopes bio-accumulate and bio-concentrate as they climb the food chain and find their way into seafood, pet food and fertilizer.

Several countries on the Pacific Rim still refuse to import fish from the area. Taiwan is demanding a cease to the pollution of the water. Consequently, Japan’s fishing community fiercely opposes any ocean dumping of Tepco’s private wastewater problem.

Over a Million Tons – Failed Fukushima Water Treatment

Nukewatch Quarterly Summer 2020

In August 2018, Tokyo Electric Power Company (Tepco), admitted that the “Advanced Liquid Processing System” or ALPS filters had failed to remove deadly radioactive materials from waste cooling water, putting the lie to its repeated assurances that ALPS would remove everything but tritium—the radioactive form of hydrogen.

News services noted, “The tritium-tainted water piling up at the crippled Fukushima No. 1 nuclear [reactor site] has been found to contain other radioactive substances, defying the defunct plant’s special treatment system, Kyodo News has learned.”

Nine years since the disaster began, tons of cooling water are still constantly poured over the amassed (melted) uranium fuel underneath destroyed reactors 1, 2, and 3 at Fukushima. Three mounds of thousands of tons hot, molten uranium fuel wreckage have to be cooled constantly to prevent new fires, explosions and major radiation releases.

Tepco told the public that iodine-129, ruthenium-106 and technetium-99 failed to be filtered by ALPS. Unlike the cesium-137 and strontium-90 that have reportedly been captured by the system and which have radioactive half-lives of roughly 30 years, iodine-129 has a half-life of 15.7 million years and persists in the environment for 15.7 million years (ten half-lives). Ruthenium-106 has a half-life of 373 days and persists for 10 years; technetium-99’s half-life is 211,000 years and it persists for 2.11 million years.

Tepco said in 2018 it had not checked the levels of radioactive materials in each tank. As of Jan. 23, 2020, there were over 680 tanks on site holding 1,184,858 cubic meters—over a million tonnes—of the liquid radioactive waste.

Contamination & Radioactive “Hot Spots” in Fukushima Endanger Returnees, Olympic Games

One of the 70,000 workers involved in cleanup efforts after the Fukushima disaster indicates bag placement of radioactive waste from Fukushima.
Nukewatch Quarterly Summer 2020

A March report by Greenpeace Japan, “Radioactivity on the Move 2020,” is a stark reminder of the daunting and endless radiation hazards caused by the triple reactor meltdown of 2011 at the Fukushima-Daiichi complex.

In Fukushima Prefecture, spring snow melt and heavy rains remobilize stocks of radio-cesium in forests, hill slopes, and floodplains that were heavily contaminated by the radiation disaster, and that then contaminate areas downstream—frustratingly, even areas that were already decontaminated. “… as a result of the contamination in 2011, these uphill forests serve as a long-term source of radioactivity for the areas below. The principle radioactive source, cesium-137, has a half-life of 30 years, and therefore will remain a hazard for around ten half-lives, or 300 years.

Conducted soon after the October 2019 Typhoon Hagibis, which was one of the most powerful typhoons in 100 years, the group’s survey “observed concentrated radiation levels throughout Fukushima Prefecture, including significant radiation hotspots….” Building on its 2016 report “Radiation Reloaded,” Greenpeace’s extensive radiation survey raises alarms about the re-contamination caused by Hagibis, “which released radioactive cesium [downhill] from the forested mountains of Fukushima prefecture which make up 70% of the region, and which cannot feasibly be decontaminated.”

The report paints an accusatory picture of Japan’s government, “Which continues to push its propaganda of normalization in Fukushima,” in order to convince the public in general and evacuees in particular that it is safe to return to their houses. The report notes that “the Japanese government remains committed to policies which aim to pressure tens of thousands of Japanese Internally Displaced Persons  to return to their former homes.”

The government’s resettlement push is also motivated by the huge economic investment in hosting the postponed summer Olympics. The games have been put off until July 23, 2012, not because of the radioactive dangers documented and presented to the government by Greenpeace Japan, but because of the coronavirus pandemic.

One example of the government’s recklessness, is its arbitrary setting of radiation exposure allowances. Global standards for radiation exposure are set by the International Commission on Radiation Protection, and the maximum exposure for the general public in Japan was one (1) milliSievert per year (mSv/y) until 2012.

But in April 2012, the government increased the maximum annual exposure twenty-fold, to 20 milliSieverts per year (20 mSv/y). This eye-popping increase of allowable exposure applies across-the-board to infants and children, while girls and women are all known to be more vulnerable to the harmful effects of radiation than adult men. Greenpeace says this was done “as part of its strategy to lift evacuations orders.”

The typhoon’s recontamination and resulting levels of potential radiation exposure have caused a “… radiological situation in Fukushima prefecture, specifically in both the open and exclusion zones of Namie, Iitate, and Okuma, [that] leads Greenpeace Japan to conclude that levels remain too high for the safe return of thousands of evacuees to these areas,” the report says. “Namie, Iitate, Okuma and Futaba remain highly contaminated.”

In its consideration of areas where evacuation orders have already been lifted, the report is highly critical. “Japanese government maintains that exposure to 20 mSv/y is acceptable in these lifted evacuation order areas. This is despite clear scientific evidence of the cancer risks from low dose radiation exposure in the 1-5 mSv/y range, which the Japanese government continues to disregard.”

Decontamination efforts have been a large part of the government’s strategy of returning people to areas hit with radioactive fallout. Yet decontamination has been less effective around houses located close to hillside forests, “where decontamination is not possible.”  Unfortunately, the report notes, “radioactivity from the non-decontaminated forest might re-contaminate the already decontaminated area below and closer to houses.”

In addition, radioactive particles and organic matter carried down from forests and fields with heavy rains and typhoons “will create continuing, subsequent influxes of radio-cesium in lakes and coastal ecosystems for years and decades to come,” the report notes. “In particular, typhoons cause significant increases in cesium discharges into the Pacific Ocean.”

The survey also discovered high levels of radiation and multiple radiation “hotspots” in Fukushima City, the J-Village sports complex and along the route of the Olympic Torch run. These findings directly challenge the government’s “propaganda narrative” leading up to the Olympic Games, and endanger athletes and everyone else involved with the games.

Reactors at War

Nukewatch Quarterly Summer 2020

Defense News reports that US military planners are seeking design ideas for small nuclear reactors that can supply electricity to combat operations in war zones. The Pentagon has given contracts to BWX tech, Westinghouse GS, and X-energy, launching a two-year design competition for a small reactor made to be “forward deployed with forces outside the United States.” Lt. Col. Robert Carver, a Pentagon spokesman told Defense News the reactor(s) would serve “a variety of [military] missions such as generating power for remote operating bases.”

The competition is for a small, portable prototype reactor potentially used in the midst of combat-riddled wars of occupation. The Pentagon’s spokespersons refer repeatedly to the plan’s “safety.” Carver told Defense News the plan “involves the development of a safe, mobile and advanced nuclear micro-reactor.” And program manager Jeff Waksman said in a Pentagon statement, that the plan’s “uniqueness lies in the reactor’s mobility and safety.”

While a more dangerous wartime target can hardly be imagined, the poison-powered war plan is only one of two. Pentagon and Department of Energy workers are currently running a pilot scheme for a small reactor, testing it at the DOE’s civilian Idaho National Laboratory, according to Pentagon spokesman Lt. Col. Mike Andrews.

Edwin Lyman, director of the Nuclear Safety Project at the Union of Concerned Scientists, believes that the Pentagon has “consistently underestimated” the “spectrum of mission risks posed by these micro-reactors,” especially in war zones. Reactors could be attacked or radioactive fuel material could be stolen and used in potential “dirty bombs.” -JL
