Tepco’s License to Kill: Japan’s Dispersal of Radioactive Waste — No Accident Anymore

South Korean protesters lampooned Japanese authorities who said you could drink the 1.37 million tonnes of radioactive wastewater they began pumping into the Pacific Ocean Aug. 24.

 

By John LaForge

Japan is set to start pumping millions of gallons of radioactive waste into the Pacific Ocean on Thurs., August 24, from Tokyo Electric Power Co.’s (Tepco’s) devastated triple reactor meltdown site at Fukushima.

This deliberate contamination of the public commons — no accident this time — is a license to kill, a criminally reckless endangerment of sea life and the food web. Yet the 1992 ban on ocean dumping of radioactive waste applies only to barrels thrown from ships, not liquids sent into the sea through pipes. Further, the Law of the Sea allows victims to bring legal action only after an alleged harm has occurred, and then puts the burden of proof on victims to show that their illness(es) were caused by a particular radioactive poison.

The nuclear industry and its government protectors run this game of radioactive waste dispersal using bailouts, bribes, and the lengthy “latency period” — the time between one’s radioactive contamination and the appearance of cancer, heart disease, etc. — which produces radiation victims years or decades after the “Fuku sushi” they ate. The nuclear industry has always depended on the fact that its chance of losing a radiation damage lawsuit is somewhere between a slim one and a fat one.

The catastrophic Fukushima earthquake-tsunami-meltdown-cubed has forced Tepco’s overseers of the three ferociously radioactive masses of melted uranium/plutonium fuel, or “corium,” to continuously pour cold water on to the unapproachable wreckage. Combined with rivers of groundwater that gushes through quake-smashed cracks in reactor foundation, the water becomes poisoned with radioactive uranium, cobalt, strontium, cesium, plutonium, and more. The failed Advanced Liquid Processing System (ALPS) has not removed these or other deadly isotopes from the wastewater now stored onshore in giant tanks. The New York Times reported Aug. 21 that, “According to Tepco’s website, just 30 percent of the approximately 473,000 tons of water in the tanks have been fully treated to the point that only tritium remains.”

Spewing radioactivity is standard industry practice

It’s no surprise that reactor-friendly governments and the International Atomic Energy Agency (whose mission is to promote nuclear reactor proliferation and to lie about radiation risks), have given Japan’s oceanic pollution scheme their seal of approval. All of them have repeatedly declared that dumping radioactive wastes into public water bodies is ordinary industrial practice and legal around the world. With straight faces, the authorities chant in unison that reactor operations contaminate the environment with radioactive liquids all day, every day, and this is somehow intended to demonstrate that such contamination is natural and danger “negligible.”

At La Hague, France and at Sellafield, England, giant reactor waste complexes process waste fuel rods, producing billions of gallons of highly radioactive liquids, and for decades the carcinogenic offal has been pumped directly into the North Sea (by France) and the Irish Sea (by England). Dr. Chris Busby, scientific secretary of the European Committee on Radiation Risk which studied internal radiation contamination, has found cancer clusters among children along the Irish seacoast — likely caused by internal exposure to Sellafield’s radioactive emissions.

Scientists, ecologists, medical authorities, environmentalists, historians, and oceanographers have repeatedly pointed out that there are practical alternatives to the dumping, and that nothing positive can result from adding radioactive pollution to the environment and the food web. The British Medical Journal only last week published the latest in a long series of studies [1] that have found again and again that exposure to low levels of radiation is more harmful than scientists previously thought. [2]

The Japanese government and Tepco hope that their global dispersal of reactor disaster waste will save the industry enough money that it can stay afloat against the astronomical costs of post-Fukushima liability and disaster response. But like the plague of mass shootings in the United States, Thursday’s start of Japan’s globalized pollution solution raises the chaos and deadliness of reactor operations to new heights, while the authorities claim from their bribery zones that nothing can be done about either hand guns or nuclear reactors.

Domino Effect: 12-Year Series of Failed Fixes at Fukushima

By John LaForge

Japan’s record-breaking earthquake and tsunami waves of March 2011— which first smashed the reactors’ foundations and the electrical grid, then destroyed back-up power generators — led to a “station blackout” and the meltdown of three large reactors at Fukushima Daiichi.

At the time, Tokyo Electric Power Co. (Tepco) had refused to upgrade its sea wall to a sufficient height, although the firm had been warned of the risk of extreme tsunamis. The result was a catastrophic, unprecedented simultaneous triple reactor meltdown: a radioactive pollution catastrophe that has never before been seen on Earth.

Although Tepco’s cost-cutting on the sea wall was only the first in a string of pollution-intensive failures that have followed like dominoes, it led in July 2022 to convictions of four top Tepco executives for negligence and a fine of $92 billion. Tepco itself had predicted in June 2008 that the site could be hit by a tsunami over 50 feet in height after a major earthquake.

South Korean protesters lampooned Japanese authorities who said you could drink the 1.37 million tons of radioactive wastewater they intend to pump into the Pacific Ocean.

In the 12 years since the meltdowns, Tepco’s disaster response efforts, always heralded as “fixes,” have been a series of hugely expensive failures: the “advanced” wastewater filter system “ALPS” has failed; the groundwater “ice wall” barrier has failed; containers made for radioactive sludge left by ALPS have failed; and plans to deal with millions of tons of collected debris now kept in plastic bags are being fiercely resisted by Japanese citizens.

Tons of cooling water is still poured into Fukushima’s triple wrecks every day to keep the hot melted fuel from again running amok. Additionally, groundwater continues to gush through countless foundation cracks and fissures caused by the earthquake, into what’s left of the structures’ sub-floors. All this water becomes highly radioactive as it passes over and through the three giant masses, some 880 tons, of melted and mangled uranium and plutonium fuel.

You read that right. Fukushima’s destroyed reactor No. 3 was using “mixed oxide” fuel made with plutonium, which is a major piece of the three deadly corium masses. (See sidebar on this page.) This plutonium contaminates not just the cooling water and groundwater contacting the melted fuel, but the ALPS apparatus and its filters, and the containers used to store the highly radioactive waste sludge extracted by ALPS.

Failed ALPS means million-tonne do-over

Tepco’s jerry-rigged system dubbed Advanced Liquid Processing System (ALPS) has never worked as planned. “The ALPS system failed to reduce radioactive elements, as claimed by the owner,” Power Technology, reported June 2, 2021. Senior East Asia Greenpeace researcher Shaun Burnie wrote in June 2023, “The ALPS has been a spectacular failure.”

Tepco has repeatedly said ALPS would remove 62 radioactive materials — all but tritium and carbon-14 from the continuously expanding volume of wastewater. Some of the deadly isotopes picked up when the water runs over and through the three melted masses of reactor fuel include cesium, strontium, cobalt, ruthenium, carbon-14, tritium, iodine, plutonium, and over 54 others.

Consequently, Tepco says it will re-filter over 70 percent of the 1.37 million tonnes of wastewater stored in giant tanks on site. Approximately 875,000 tons of contaminated water must be put through the system again, a process that will leave behind more of the highly radioactive and corrosive waste sludge.

Shaun Burnie’s reporting on ALPS is worth quoting at length:

“About 70 percent or 931,600 cubic meters of the wastewater needs to be processed again (and probably many more times) by the ALPS to bring the radioactive concentration levels below the regulatory limit for discharge. Tepco has succeeded in reducing the concentration levels of strontium, iodine, and plutonium in only 0.2 percent of the total volume of the wastewater, and it still requires further processing. But no secondary processing has taken place in the past nearly three years. Neither Tepco nor the Japanese government [have] said how many times the wastewater needs to be processed, how long it will take to do so, or whether the efforts will ever be successful. Greenpeace reported on these problems and why the ALPS failed nearly five years ago, and none of these issues has been resolved.”

Ice wall also melts

Tepco intended to reduce the volume of groundwater gushing into the reactor building foundations by digging a $350 million “ice wall” into the earth between the destroyed reactors and the mountains behind. The company placed 1,568 heavy pipes filled with coolant 90 feet deep. It was to freeze the ground to form a deep impenetrable barrier, diverting groundwater to either side of the destroyed six-reactor Fukushima complex and prevent it seeping inside. It has failed to do so. In 2016, the Times of London reported that the scheme had only a “minor impact” on the volume of groundwater rushing in, which at the time still averaged 321 tonnes a day. Tepco announced then that it would retrofit the system and fix the leaks, but Science/The Wire reported in January 2022 that the company had admitted that its ice wall was “partially” melting. About 150 tonnes per day still gushes in.

Filtered sludge burning through containers

The ALPS filter has produced over 4,000 large containers filled with highly radioactive slurry and sludge left from the treatment.

Like the use of the word “advanced” in the name of the failed ALPS machinery, the heavy cylinders used for the caustic, highly radioactive sludge are called “High Integrity Containers” or HICs. In fact they are made of plastic and have degraded far faster than Tepco anticipated.
By March 2, Tepco had filled 4,143 containers, according to the daily Asahi Shimbun. At 30 cubic feet each, the cylinders now store a total of about 124,290 cubic feet of the highly radioactive sludge that will soon require expensive repackaging and, eventually, isolation from the biosphere for thousands of years.

Over two years ago, on June 8, 2021, Japan’s Nuclear Regulation Authority (NRA) announced that 31 of the containers had “exceeded their lifespans” and were corroded badly enough by the harsh toxic material that they must be replaced. The NRA also warned that another 56 cylinders would need replacing within two years.

Japan’s Mainichi newspaper reported that the government regulators blamed Tepco for “underestimating the radiation the 31 plastic cylinders were exposed to.” The company then claimed it would start moving the contents to new containers.

The Asahi Shimbun reported April 27, 2023, that the HICs must be stored in concrete boxes that can block radiation.

Rad waste to be dumped, deregulated

As we go to press, Tepco has begun testing its large tunnel, with which it intends to begin dispersing 1.37 million tonnes of contaminated wastewater into the Pacific Ocean. The government has steadfastly ignored fierce local and international opposition to the plan from the fishing community, marine scientists, Pacific Island nations, environmentalists, South Korea, and China. So far only South Korean politicians have suggested bringing international legal action against the dumping.

Since the 2011 meltdowns spewed radioactive materials broadly across Japan’s main island, some 22-million tonnes of cesium-contaminated soil, leaves, and debris have been scraped from the ground and stored in large bags. Citizens are struggling desperately prevent authorities from using the radioactive waste in road building or burning it in incinerators. The bags are currently stacked in tens of thousands of piles all over the region.

Even more protest was raised last February when the NRA announced it would allow Tepco to severely weaken its monitoring of radioactivity in the dumped waste. The NRA said it reduced the number of radioactive elements to be measured from 64 to 34.

The environment minister of Hong Kong, a coastal metropolis of 7.5 million people, charged in June that Japan is “violating its obligations under international law and endangering the marine environment and public health.” Minister Tse Chin-wan wrote in the daily Ta Kung Pao that the city would “immediately prohibit imports of seafood caught off the coast of Fukushima prefecture.”

Plutonium Spread Long Distances from Fukushima

By John LaForge

Very few reports of the Fukushima catastrophe have mentioned plutonium contamination. Yet plutonium was used in fuel rods in Fukushima’s reactor 3 which was destroyed by meltdown and several hydrogen explosions.

Following the March 14, 2011 explosion at reactor 3, experts worried about the release of the extremely dangerous radioactive substances. Then a week later, on March 21 and 22, Tepco announced that it had detected plutonium in soil collected from its compound.

Plutonium is one of the most toxic substances known to science, and fine particles are far more biologically hazardous than larger particles.

Now, studies published in the journals Science of The Total Environment, Nov. 15, 2020, and Chemosphere, July 2023, report that researchers found that cesium and plutonium “were transported over long distances,” and that deposits of them were recorded in “downtown Tokyo,” about 142 miles from the meltdowns.

According to the authors, very high concentrations of radioactive cesium were released during the accident as particles referred to as “cesium-rich microparticles” (CsMPs). The researchers say CsMPs they found are mainly composed of silicon, iron, zinc, and cesium, and minor amounts of radioactive tellurium, technetium, molybdenum, uranium, and plutonium.

The studies, involving scientists from six countries and led by Associate Professor Satoshi Utsunomiya, a researcher at Kyushu University, found that “plutonium was included inside cesium-rich microparticles that were emitted from the site.”

Radioactive CsMPs released from Fukushima are a potential health risk through inhalation. “Given the small size of the particles, they could penetrate into the deepest parts of the lung, where they could be retained,” Utsunomiya wrote. “The route of exposure of greatest concern is inhalation,” the authors reported, because plutonium, lodged in the lungs, can “remain for years.”

Utsunomiya summed up his team’s work saying, “It took a long time to publish results on particulate Pu from Fukushima … but research on Fukushima’s environmental impact and its decommissioning are a long way from being over.”

Failed Fukushima System Should Cancel Wastewater Ocean Dumping

Photo Credit: https://eandt.theiet.org/content/articles/2021/04/contaminated-water-from-fukushima-nuclear-plant-to-be-released-into-the-ocean/.

By John LaForge, PeaceVoice, 22 July 2023

From the Fukushima-Daiichi triple-reactor meltdown wreckage, Japan’s government and “Tepco,” the owner, are rushing plans to pump 1.37 million tons (about 3 billion pounds) of radioactive wastewater into the Pacific.

Their record is poor. Their lies are documented. This is not safe, at all.

To keep the three meltdowns’ wasted fuel from melting again, Tepco continuously pours cold water over 880 tons of “corium,” the red-hot rubblized fuel amassed somewhere under three devastated reactors. “That water leaks into a maze of basements and trenches beneath the reactors and mixes with groundwater flowing into the complex,” Reuters Reported Sep. 3, 2013.

Most of this water is collected and put through Tepco’s jerry-rigged mechanism dubbed ALPS, for Advanced Liquid Processing System, which it turns out hasn’t processed much of anything.

Tepco, Japan’s Nuclear Regulatory Authority, the International Atomic Energy Agency (IAEA), and much of the media endlessly repeat that ALPS removes over 62 radioactive materials from the ever-expanding volume of wastewater. Reports Regularly Claim the planned dumping is routine, safe, and manageable.

This unverified PR loop has fooled a lot of people, but the ALPS is a fraud. As early as 2013, The Filter System Stalled and the IAEA reported that April that ALPS had not “accomplished the expected result of removing some radionuclides,” Reuters Reported.

In September 2018, the ALPS was revealed to have drastically failed, Forcing Tepco To Issue A Public Apology and a promise to re-filter huge volumes of the waste.

According To Reuters, Oct. 11, 2018, documents on a government committee’s website show that 84 percent of water held at Fukushima contains concentrations of radioactive materials higher than legal limits allow to be dumped.

Among the deadly isotopes still in the waste are cesium-137, strontium-90, cobalt-60, ruthenium, carbon-14, tritium, iodine-129, plutonium isotopes, and more than 54 more.

In a June 14, 2023 op/ed for the China Daily, Shaun Burnie, the Senior Nuclear Specialist at Greenpeace East Asia, reported that The ALPS “Has Been A Spectacular Failure,” and noted:

“About 70 percent or 931,600 cubic meters of the wastewater needs to be processed again (and probably many more times) by the ALPS to bring the radioactive concentration levels below the regulatory limit for discharge. Tepco has succeeded in reducing the concentration levels of strontium, iodine, and plutonium in only 0.2 percent of the total volume of the wastewater, and it still requires further processing. But no secondary processing has taken place in the past nearly three years. Neither Tepco nor the Japanese government has said how many times the wastewater needs to be processed, how long it will take to do so, or whether the efforts will ever be successful. … none of these issues has been resolved.”

Tepco says it will re-filter more than 70 percent of the wastewater through ALPS again, a process that itself leaves massive amounts of highly radioactive sludge that must be kept out of the environment for centuries.

Hoping to slow the rush to dump, Professor Ryota Koyama from Fukushima University, Said In An Interview With China Media Group last May, “If the Japanese government or the Tokyo Electric Power Co. really wants to discharge contaminated water into the sea, they need to explain in more detail whether the nuclides have really been removed.”

International law governing state-sponsored or corporate pollution of the seven seas is relatively useless in challenging Tepco’s outrageous transfer of private industrial poison into the public commons. The global ban on ocean dumping of radioactive waste adopted in 1993 applies only to barrels. It has allowed Britain and France to pump billions of gallons of radioactive wastewater into the Irish Sea and the North Sea respectively, for decades.

The Law of the Sea might be able to bring Japan’s deliberate poisoning to an end only after a victim or class of victims harmed by Tepco’s meltdown waste brings a lawsuit that proves it. But showing that your illnesses or cancers were caused by ingested or inhaled radiation is so difficult that the nuclear power and weapons industry has skated along for 70 years — routinely and legally venting, leaking, releasing and dumping radioactive materials — without comeuppance.

Radioactivity is colorless, odorless, and invisible. Birth defects and cancers caused by exposure to ionizing radiation are entirely too visible.

Failed Fukushima Fixes Falling Like Dominoes

By John LaForge

Japan’s breathtaking earthquake and tsunami waves of March 11, 2011— which first smashed the Fukushima Daiichi reactors’ foundations and the electrical grid, and then destroyed all its back-up power generators — led to a “station blackout” and the meltdown of three large reactors and to hydrogen explosion that blew apart four reactor containment structures.

Before the disaster, Tokyo Electric Power Co. (Tepco) had refused to sufficiently upgrade its protective sea wall, although it had been warned of the risk of extreme tsunamis. The site was hit by a tsunami of a height of 46 feet, but Tepco had prepared for a wave of up to only 18 feet.  (Fukushima Meltdown: The World’s First Earthquake-Tsunami-Nuclear Disaster, Takashi Hirose, p. 30) The result was a catastrophic, unprecedented simultaneous triple reactor meltdown: an earthquake-tsunami-radiation event that had never before been seen on Earth.

Tepco’s cost-avoidance on its sea wall was only the first in a string of failures that have followed like dominos. The corruption led in July 2022 to convictions of four top Tepco executives for negligence and a fine of $95 billion.

In the 12 years since the meltdowns, Tepco’s disaster response efforts, always heralded as fixes, have been a series of hugely expensive failures: the “advanced” wastewater filter system “ALPS” has failed; the buried “ice wall” groundwater barrier has failed; containers made for the radioactive sludge produced by ALPS have failed; and plans to deal with millions of tons of collected debris — now kept in plastic bags — are being fiercely resisted by Japanese citizens.

Tons of cooling water is still being poured every day into Fukushima’s triple reactor wrecks to keep the hot melted fuel from again running amok. Additionally, groundwater gushes through the reactors’ foundations’ countless cracks and breaks caused by the staggering earthquake into what’s left of the structures’ sub-floors. All this water becomes highly radioactive as it passes over and through three giant masses — totaling at least 880 tonnes — of melted and mangled uranium and plutonium fuel.

You read that right. Fukushima’s destroyed reactor No. 3 was using fuel made partly of plutonium (see below), and so plutonium contaminates not just the ground and cooling water running over the melted fuel, but the ALPS apparatus, its filters, the containers used to store the radioactive sludge extracted by ALPS, and of course the sludge itself. You would think that the word plutonium would appear occasionally in news coverage of this ongoing disaster.

Failed ALPS means million-tonne do-over

Tepco’s jerry-rigged system dubbed Advanced Liquid Processing System or ALPS has never worked as planned. As early as 2013 the machinery was stalled. “The ALPS system failed to reduce radioactive elements, as claimed by the owner,” Power Technology, reported June 2, 2021.

Tepco has repeatedly said ALPS would remove 62 radioactive materials — all but tritium and carbon-14 from the continuously expanding volume of wastewater. Documents on a government committee’s website show that of 890,000 tonnes of water held at Fukushima, 750,000 tonnes, or 84 percent, contain higher concentrations of radioactive materials than legal limits allow, according to Reuters, Oct. 11, 2018. Among the long-lasting and deadly isotopes picked up by the water runs that through melted fuel wreckage are cesium, strontium, cobalt, ruthenium, carbon-14, tritium, iodine, plutonium, and at least 54 others.

In a June 14 op/ed for the China Daily, Shaun Burnie, the Senior Nuclear Specialist at Greenpeace East Asia, reported that the ALPS “has been a spectacular failure” and noted that:
