Japan’s decision to dump Fukushima water is based on biased data, argue scientists

A panel of scientists is arguing that the Japanese government’s decision to discharge radioactive water from the Fukushima nuclear plant into the ocean is based on incomplete and biased data.

The experts contend that Tokyo Electric Power Company (TEPCO), the operator of the nuclear plant, concluded that the contaminated water was safe without properly measuring a significant number of radioactive materials (nuclides). The discharge of the wastewater from the Fukushima plant could begin as soon as this coming spring.

This latest analysis comes from a panel of scientists organized by the Pacific Islands Forum (PIF), an intergovernmental organization made up of 18 Pacific Island countries including New Zealand and Fiji.

These scientists are recommending the Japanese government cease its plans to release the wastewater from the nuclear plant into the ocean and instead seek alternative options.

At a debate held at Korea’s National Assembly on Thursday, the scientists stressed that TEPCO’s contaminated water measurement data cannot function as the basis for deciding on the release of the wastewater into the ocean.

The panel of scientists, including five experts in nuclear energy and oceanography, was formed last March by the PIF. As parties with a direct stake in the consequences of the potential discharge of Fukushima wastewater, the PIF requested relevant information and data from Japan regarding this issue.

On Jan. 13, the Japanese government decided to dilute 1.3 million tons of contaminated water stored in over 1,000 tanks at the Fukushima plant with water and then to release it into the ocean either this coming spring or summer.

“The data provided by Japan to the forum is incomplete, inadequate, inconsistent, and biased, making it unsuitable for making any decisions,” said Dr. Ferenc Dalnoki-Veress, an adjunct professor at the Middlebury Institute of International Studies and head of the panel of scientists.

“Since wastewater is not being released into nature in a planned or controlled way from a normally functioning power plant, in this case the word ‘dumping’ should be used instead of the ‘release’ of wastewater,” Dalnoki-Veress said.

The reason the panel believes the data provided by TEPCO is biased is that TEPCO is focusing only on nine materials, including strontium and cesium, among a total of 64 radioactive materials. The remaining 55, which were not measured, are presumed to be always present with the same effect.

The panel of scientists also pointed out that it is not enough to gauge the actual composition and concentration levels of the wastewater as the measurement of materials was performed on a 30-liter sample just before the water in the storage tanks to be treated with the Advanced Liquid Processing System (ALPS) were full.

In a report published by the panel on this issue, the scientists raised fundamental questions about the reliability of the Japanese data, saying there are “many abnormal and suspicious measurement values in TEPCO’s measurement data.

” For example, the panel pointed out that measurements for tellurium (Te)-127, a radionuclide with a half-life of only 9.4 hours, ranged from hundreds of thousands to nearly tens of billions of becquerels (Bq) per liter. This is because, if it had been released during the Fukushima accident, it would have broken down a long time ago in terms of its half-life.

“Unless the core is intermittently in a dangerous state of meltdown, these measurements indicate problems with TEPCO’s measurement and data quality control procedures,” the report stated.

The panel also pointed out the major problem that issues such as how tritium present in the wastewater is changed into organic-bonded tritium in the sea, which will affect the marine ecosystem, or the effects of strontium-90’s bioconcentration, are not being properly examined.

“The assumption that dilution is the solution to pollution is scientifically outdated and ecologically inadequate,” the panel said. “The [wastewater] dumping measures are an issue that transcends generations and borders and require much greater contemplation,” they added.

As an alternative to releasing the polluted water into the ocean, the scientists recommended the wastewater be stored for a long time to reduce its radioactivity levels until the polluting elements can be removed using biological methods such as employing animals, plants and fungi. After this, the treated water could be used in the process of making concrete in places with as little human contact as possible.

Don’t dump on us

Pacific Islanders, marine scientists, urge Japan not to dump Fukushima radioactive water into ocean

By Linda Pentz Gunter

The nuclear power industry has a long history of disproportionately impacting people of color, Indigenous communities and those living in the Global South. As Japan prepares to dump more than 1 million tonnes of radioactive water from its stricken Fukushima-Daiichi nuclear power plant site into the Pacific Ocean some time this year, history is about to repeat itself.

To remind us of that — and to warn against this reckless and entirely unnecessary action (Japan could and should expand the cask storage pad on site and keep storing the radioactive water there) — the leader of the Pacific Islands Forum (PIF) has spoken out.

In a recent column in the UK daily newspaper, The Guardian, Henry Puna wrote that “continuing with ocean discharge plans at this time is simply inconceivable”, given how directly it once again discriminates against — and will likely seriously harm the health of — the peoples of the Pacific. Puna took care to remind readers “that the majority of our Pacific peoples are coastal peoples, and that the ocean continues to be an integral part of their subsistence living.”

Japan is once again declaring its intention to dump the radioactive water stored in tanks at the Fukushima-Daiichi nuclear site into the Pacific Ocean, against widespread opposition.

Going forward with the dump without further study and serious consideration of viable alternatives, would, Puna said, mean that “the region will once again be headed towards a major nuclear contamination disaster at the hands of others.” Victims of years of atomic testing, Pacific Islanders are rightly not ready to be dumped on yet again.

Tepco and the lapdog Japanese government announced last May that they would release around 1.3 million tonnes of radioactive waste water from the Fukushima site next spring. Recently, authorities suggested the dump could be delayed until the summer but seem undeterred by the loud chorus of opposition from multiple quarters.

The plant produces 100 cubic metres of contaminated water daily, a combination of groundwater, seawater and water used to keep the reactors cool. The water is theoretically filtered to remove most harmful isotopes, other than tritium, which is radioactive hydrogen and cannot be separated from water. It is then stored in casks on site where authorities claim they are running out of space. However, independent watchdogs are not convinced that the filter system has successfully removed other dangerous radioactive isotopes from the waste water.

Most recently, the 100-member American group, the National Association of Marine Laboratories (NAML), expressed its fervent opposition in a strongly worded position paper released last month. Their opposition, they wrote, “is based on the fact that there is a lack of adequate and accurate scientific data supporting Japan’s assertion of safety. Furthermore, there is an abundance of data demonstrating serious concerns about releasing radioactively contaminated water.”

The report went on: “The proposed release of this contaminated water is a transboundary and transgenerational issue of concern for the health of marine ecosystems and those whose lives and livelihoods depend on them. We are concerned about the absence of critical data on the radionuclide content of each tank, the Advanced Liquid Processing System (ALPS), which is used to remove radionuclides, and the assumption that upon the release of the contaminated wastewater, ‘dilution is the solution to pollution.’”

The scientists accused Japan of ignoring the inevitable processes of bioaccumulation and bioconcentration, which contradict the dilution contention. The Association also called out what it saw as shoddy or incorrect science conducted by Tepco and the Japanese government, including “flaws in sampling protocols, statistical design, sample analyses, and assumptions, which in turn lead to flaws in the conclusion of safety and prevent a more thorough evaluation of better alternative approaches to disposal.”

Japan has consistently rejected on-going onsite storage — presumably due to the expense, given the land space is there and more casks could be provided. In the view of some, the eagerness to dump the water— largely contaminated with tritium (a form of radioactive hydrogen that cannot be separated from water) and likely other undeclared radionuclides — is a public relations exercise to make the problem “go away” and restore normal optics to the site. The site cannot also be fully decommissioned so long as the tanks are there.

Castle Bravo was just the largest of the 67 atomic tests conducted by the US in the Marshall Islands, contaminating the landscape and sickening its population for generations .

Japan has also benefited from the (inevitable) support of the (nuclear power-promoting) International Atomic Energy Agency, an organization that never met a nuclear danger it couldn’t downplay. The agency has described the proposed discharges as “far below the Japanese regulatory limits,” in a statement last April.

After sending in a task force and several earlier reports, the IAEA released a new report in December in which it said “the IAEA will conduct its own independent checks of the radiological contents of the water stored in the tanks and how it will analyse environmental samples (for example seawater and fish) from the surrounding environment.” However, the IAEA has not expressed opposition to the dumping of the radioactive water even now and instead indicates that its safety reviews will continue “before, during, and after the discharges of ALPS treated water.”

Japan has faced down opposition from fishermen and environmentalists, particularly from those in the Marshall Islands who have suffered decades of horrific health issues, especially birth defects, after enduring 67 US atomic tests there. A Pacific region collective advocacy group, Youngsolwara Pacific, expressed dismay that the Japanese, of all people, would not empathize with them and condemn the Fukushima water dump.

“How can the Japanese government, who has experienced the same brutal experiences of nuclear weapons in both Hiroshima and Nagasaki, wish to further pollute our Pacific with nuclear waste?” they asked in a statement quoted in a New York Times article in December. “To us, this irresponsible act of trans-boundary harm is just the same as waging nuclear war on us as Pacific peoples and our islands.”

Pacific Islanders are naturally suspicious, having been lied to before. It took two days before the by then radiologically contaminated people of Rongelap were evacuated subsequent to the massive Castle Bravo atomic test, America’s biggest bomb that devastated Bikini Atoll. Marshall Islanders were treated as guinea pigs in the aftermath of the tests there, as the US government examined the impact on people living in a radiologically contaminated environment — even as the true dangers were hidden from them. Consequently, claims by the Japanese government that their Advanced Liquid Processing System had removed the worst of the radionuclides from the waste water to be dumped, have been met with skepticism at best.

Now, their concerns are supported by marine scientists.

“The effectiveness of the Advanced Liquid Processing System in almost completely removing the over 60 different radionuclides present in the affected wastewater—some of which have an affinity to target specific tissues, glands, organs, and metabolic pathways in living organisms, including people—remains a serious concern due to the absence of critical data,” said the statement from NAML.

Those are precisely some of the agonizing health effects already endured by the bombed peoples of the Marshall Islands and elsewhere in the Pacific. They are not ready to be dosed again. 

“You feel this deep sorrow,” Bedi Racule, President of the Marshall Islands Students Association, told the New York Times. “Why were we not good enough to be treated like human beings?”

In an August 2022 statement on the Youngsolwara Pacific homepage, Racule added: “The impact of the nuclear testing legacy in the Pacific continues to affect our islands and people, and we cannot afford another scenario such as Fukushima’s dumping plan. Scientists are already warning that the impact of long-term, low-dose exposure to not only tritium but also other isotopes on the environment and humans is still unknown and that release of the wastewater is premature.”

Now NAML, the PIF and a vociferous alliance of Japanese fishermen and anti-nuclear activists, are raising their voices a little louder in what might be a last ditch attempt to prevent the Pacific Ocean from becoming, once again, a nuclear dustbin.

Fukushima’s Toxic Dumping Flashpoint

January 20, 2023

by Robert Hunziker

“We must remind Japan that if the radioactive nuclear wastewater is safe, just dump it in Tokyo, test it in Paris and store it in Washington, but keep our Pacific nuclear-free.” (Vanuatu’s celebrated former ‘Turaga Chief’ Motarilavoa Hilda Lini)

In the face of considerable worldwide criticism, TEPCO is moving ahead with its well-advertised plans to dump contaminated water from storage tanks at the Fukushima-Daiichi Nuclear Power Plant disaster zone into the Pacific Ocean. They are running out of storage space and the Pacific Ocean is conveniently right next door.

The Japanese government is courting trouble, as a contracting party to: (1) the United Nations Convention on the Law of the Sea (2) the Convention on Early Notification of a Nuclear Accident, and (3) the Convention on Nuclear Safety, Japan has knowingly violated all three conventions by making the decision to dump contaminated water into the Pacific Ocean.

TEPCO’s toxic dumping scheme is opposed by some scientists as well as some of the world’s most highly regarded marine laboratories, e.g., the U.S. National Association of Marine Laboratories, with over 100 member laboratories, has issued a position paper strongly opposing the toxic dumping because of a lack of adequate and accurate scientific data in support of Japan’s assertions of safety.

The position paper: “We urge the government of Japan to stop pursing their planned and precedent-setting release of the radioactively contaminated water into the Pacific Ocean and to work with the broader scientific community to pursue other approaches that protect ocean life; human health; and those communities who depend on ecologically, economically, and culturally valuable marine resources.” (Source: U.S. Marine Labs Call for Stop to Fukushima Dumping Plans for Pacific, Pacific Island Times, Dec. 20, 2022)

Furthermore, Marine Laboratories agrees with the Pacific Island Forum’s suggestion that TEPCO look at options other than discharge. The toxic dumping plan has already put Japan at risk of losing its status as a Pacific Islands Forum Dialogue Partner. There are 21 partners, including the US, China, the UK, France, and the EU. According to Secretary General Henry Puna, the Forum has persistently requested Japan to share pivotal data, which has not been forthcoming: “In fact, we are very serious, and we will take all options to get Japan to at least cooperate with us by releasing the information that our technical experts are asking of them.” (Source: Pacific Island Forum Could Sideline Japan Over Nuclear Waste Plan, RNZ Pacific, January 12, 2023)

Japan’s Nuclear Regulation Authority has endorsed the dumping plan. No surprise there. Also unsurprisingly, the International Atomic Energy Agency (IAEA), the marketing arm for nuclear power, claims the dumping proposal is safe. Effective December 29, 2022, IAEA released an extensive report that details how the process will be monitored by independent entities, not to worry, uh-uh.

TEPCO generates 100 cubic metres of contaminated water per day, a mixture of groundwater, seawater, and water that cools the reactors. It is filtered for “the most radioactive isotopes” and stored in above-ground water tanks, but authorities admit that the level of tritium is above standards. It is almost impossible to remove tritium from water. TEPCO claims it is “only harmful to humans in large doses.” But who’s measuring?

According to TEPCO: “After treatment the levels of most radioactive particles meet the national standard.” However, the statement that most radioactive particles meet the national standard is not reassuring. And furthermore, why should anybody anywhere in the world be permitted to discharge large quantities of contaminated water that’s been filtered for ‘most radioactive particles’ directly from a broken-down nuclear power plant into the ocean under any circumstances?

But storage space is running out and the ocean is readily available as a very convenient garbage dump. Well, yes, but maybe find more storage space… on land… in Japan!

According to a Japanese anti-nuclear campaign group, the contaminated water dumping scheme violates the Convention on the Prevention of Marine Pollution as well as the UN Convention on the Law of the Seas. Their opposition is endorsed by the National Fisheries Cooperative Federation of Japan. In September 2022, 42,000 people signed a joint petition delivered to TEPCO and Japan’s Ministry of Economy demanding other solutions to the toxic water dumping plans. According to national broadcasting firm NHK, 51% of Japanese respondents oppose the dumping plan. And a survey by Asahi Shimbun claims 55% of the public opposes the dumping.

A Greenpeace East Asia press release d/d April 28, 2021, says; “According to the latest report by the Japanese government, there are 62 radioactive isotopes found in the existing nuclear water tanks in Fukushima, among which concentration of a radionuclide called tritium reached about 860 TBq (terabecquerel) – an alarming level that far exceeds the acceptable norm.”

China’s Xinhua News Agency claims: “TEPCO believes that tritium normally remains in the wastewater at ordinary nuclear power stations, therefore it is safe to discharge tritium-contaminated water. Experts say TEPCO is trying to confuse the concept of the wastewater that meets international standards during normal operation of nuclear power plants with that of the complex nuclear-contaminated water produced after the core meltdowns at the wrecked Fukushima power plant. The actual results of ALPS (Advanced Liquid Processing System) are not as ideal as TEPCO claims. Japanese media have found that in addition to tritium, there are a variety of radioactive substances in the Fukushima nuclear wastewater that exceed the standard. TEPCO has also admitted that about 70 percent of the water treated by ALPS contains radionuclides other than tritium at the concentration which exceeds legally required standards and requires filtration again.” (Source: World Insights: Japan Extremely Selfish to insist on Discharging Nuclear Wastewater into Sea, Xinhua, August 10, 2022)

According to Hiroyuki Uchida, mayor of Iwaki, Fukushima Prefecture, despite strengthened information about the toxic dumping by TEPCO and the government of Japan, the discharge plan has not gained “full understanding of citizens and fishery stakeholders.” (Source: Japanese Public Opposes Plan to Dump Radioactive Water into Sea, Asia & Pacific by Xinhau, January 15, 2023)

Rhea Moss-Christian, executive director of the Western and Central Pacific Fisheries Commission, aka: the Pacific Tuna Commission said: “It’s a real concern and I just wish they would take a bit of time to think more carefully about this… this is a massive release and a big, big potential disaster if it’s not handled properly… There are a number of outstanding questions that have yet to be fully answered. They have focused a lot on one radionuclide and not very much on others that are also present in the wastewater.” (Source: Hiroshima Survivor Pleads for Halt of Radioactive Waste Dump in Pacific Ocean, INA Pacific News Service, December 20, 2022)

Greenpeace/Japan on TEPCO dumping: “The Japanese government has once again failed the people of Fukushima. The government has taken the wholly unjustified decision to deliberately contaminate the Pacific Ocean with radioactive wastes. It has discounted the radiation risks and turned its back on the clear evidence that sufficient storage capacity is available on the nuclear site as well as in surrounding districts.[2] Rather than using the best available technology to minimize radiation hazards by storing and processing the water over the long term, they have opted for the cheapest option [3], dumping the water into the Pacific Ocean… Since 2012, Greenpeace has proactively campaigned against plans to discharge Fukushima contaminated water – submitting technical analysis to UN agencies, holding seminars with local residents of Fukushima with other NGOs, and petitioning against the discharges and submitted to relevant Japanese government bodies.” (Source: Greenpeace Press Release, April 13, 2021)

Addressing the U.N. General Assembly on September 22nd, 2022, President David Panuelo of Micronesia stated: “We cannot close our eyes to the unimaginable threats of nuclear contamination, marine pollution, and eventual destruction of the Blue Pacific Continent. The impacts of this decision are both transboundary and intergenerational in nature.”

In April 2021 Japan’s Deputy Prime Minister (serving from 2012-to-2021) Tarō Asō publicly stated that the treated and diluted water “will be safe to drink.” In response to Deputy PM Asō, Chinese Foreign Minister Lijian Zhao replied: “The ocean is not Japan’s trashcan” and furthermore, since Japan claims it’s safe to drink, “then drink it!” (Source: China to Japan: If Treated Radioactive Water from Fukushima is Safe, ‘Please Drink It’ Washington Post, April 15, 2021)

Mr. Zhao may have stumbled upon the best solution to international concerns about TEPCO (Tokyo Electric Power Company) dumping contaminated water into the Pacific Ocean. Instead, TEPCO should remove it from the storage tanks at Fukushima Daiichi Nuclear Power Station and deliver it to Japan’s water reservoirs. After all, they publicly claimed it’s “safe to drink.” Japan has approximately 100,000 dams of which roughly 3,000 are reservoirs over 15 meters (50’) height. For example, one of the largest drinking water reservoirs in Japan is Ogouchi Reservoir, which holds 189 million tons of drinking water for Tokyo.
