Japan’s Fukushima plant completes third water release

Canberra Times By Mari Yamaguchi, November 20 2023 – Australian Associated Press

The release of a third batch of treated radioactive wastewater from Japan’s damaged Fukushima nuclear plant into the Pacific Ocean ended safely as planned, its operator says, as the country’s seafood producers continue to suffer from a Chinese import ban imposed after the discharges began.

Large amounts of radioactive wastewater have accumulated at the nuclear plant since it was damaged by a massive earthquake and tsunami in 2011.

It began discharging treated and diluted wastewater into the ocean on August 24 and finished releasing the third 7800-ton batch on Monday.

The process is expected to take decades.

The discharges have been strongly opposed by fishing groups and neighbouring countries including China, which banned all imports of Japanese seafood, badly hurting Japanese producers and exporters of scallops and other seafood……………………………………………………

Japan’s government has set up a relief fund to help find new markets for Japanese seafood, and the central and local governments have led campaigns to encourage Japanese consumers to eat more fish and support Fukushima seafood producers.

TEPCO is also providing compensation to the fisheries industry for “reputational damage” to its products caused by the wastewater release and said it has mailed application forms to 580 possible compensation seekers…………………………..

TEPCO and the government say the process is safe, but some scientists say the continuing release of water containing radionuclides from damaged reactors is unprecedented and should be monitored closely.

Monday’s completion of the release of the third batch of wastewater brings the total to 23,400 tons.

TEPCO plans a fourth release by the end of March 2024.

That would only empty about 10 of the approximately 1000 storage tanks at the Fukushima plant because of its continued production of wastewater, although officials say the pace of the discharges will pick up later.

The tanks currently hold more than 1.3 million tons of wastewater, most of which needs to be retreated to meet safety standards before release.

TEPCO and the government say discharging the water into the sea is unavoidable because the tanks need to be removed from the grounds of the plant so that it can be decommissioned.  https://www.canberratimes.com.au/story/8430646/japans-fukushima-plant-completes-third-water-release/

Fukushima Nuclear Power Plant starts 3rd round of wastewater release, potentially impacting seafood quality in U.S.

 The Daily Universe, Belle Lewis, November 14, 2023

The Fukushima-Dachii nuclear plant started its third release of nuclear wastewater on Nov. 2 as scientists warn that seafood products from the Pacific Ocean could be contaminated.

Although the International Atomic Energy Agency approved the 30-year water release plan, scientists and civilians in nations bordering the Pacific Ocean have questioned the safety of the plan, especially as it relates to seafood.

In a press release approving of the plan, the IAEA stated, “the discharges of the treated water would have a negligible radiological impact to people and the environment.”

Paul Dorfman, member of the Irish Government Environmental Protection Agency Radiation Protection Advisory Committee and chair of Nuclear Consulting Group, explained that some scientists have questioned IAEA’s approval of the water release.

“I and others are concerned by IAEA’s attitude,” Dorfman said. “Normally even low levels of radioactive pollution will find its way into local seafood, one way or another.”

In 2020, Japan exported 332,926 kilograms of frozen scallops to the U.S. Japan exports many fish products to the U.S.

Samantha Valeriano, a psychology student from Hawaii, said she eats seafood about once a week. She does not often think about where her food comes from but wants to be more cautious following the nuclear water release.

“I think I would be a little more cautious of what I ate, checking labels a little bit more,” Valeriano said. “I would be conscious of what I ate and where it came from.”

As the People’s Republic of China has imposed bans of Japanese fish exports, the U.S. has supported the Japanese market by increasing fish purchases.

In a press release, the United States Embassy and Consulate in Japan explained that military bases in Japan will carry Japanese seafood as a way to buoy up seafood markets and undermine the PRC’s ban.

“United States elected representatives and senior government officials have stood in solidarity with Japan during this baseless ban,” the statement said. “Another step to help provide additional sales to counter the ban was to start selling Japanese seafood at the U.S. military facilities in Japan, both through the commissaries and mess halls.”

According to the statement, government officials like former speaker Kevin McCarthy ate seafood from Japan as a testament to Japan’s safety standards.

However, other U.S. agencies, like the National Association of Marine Laboratories question whether accurate research was conducted by the IAEA and Japanese Government to determine safety of seafood products.

They explain that the lack of data on potential health impacts is a cause for serious concern.

“Many of the radionuclides contained in the accumulated waste cooling water have half-lives ranging from decades to centuries, and their deleterious effects range from DNA damage and cellular stress to elevated cancer risks in people who eat affected marine organisms, such as clams, oysters, crabs, lobster, shrimp and fish,” the statement reads.

Eve Nagareda, medical laboratory science major from Hawaii, shared she wants to avoid seafood from dumping grounds even if levels are considered safe.

“I think I would try to go as far as possible from it,” Nagareda said…………………………………………………………………………..

On Sep. 8, the IAEA conducted seawater sampling off the Japanese Coast. They recorded Tritium levels below the internationally mandated limit of 1,500 bequerels per liter.

Dorfman explained that below-accepted tritium levels does not mean that the ALPS is functioning properly.

“The Japan government and IAEA say that the treatment is sufficient, and levels of radiation, especially tritium, in the water releases are low.” Dorfman said. “However, others note that the treatment process has already failed once before, and may let through a series of radioisotopes, not only tritium.”

A pre-publication scientific paper found that radionucleotides from the Fukushima plant will distribute globally and penetrate into the deep ocean. The highest concentration of these particles would be along the eastern coast of Japan.

This paper contradicts assertions made by the IAEA that once the water is dumped into the Pacific Ocean, the particles will dilute.

Radiation experts often say that “dilution isn’t the solution to pollution,” according to Dorfman.

Why release the water?

After the water is released, the land the tanks occupy will be available for the Japanese government to build facilities to fully decommission the Fukushima-Daiichi Plant.

In the greater scheme of things, it has to be said that the main issue at Fukushima remains the almost impossible task of trying to extract the nearly 880 tonnes of highly radioactive nuclear fuel that have melted in three of the plant’s six reactors,” Dorfman said.

According to Dorfman, decommissioning is far off.

“We are a very very long way away from decommissioning Fukushima,” Dorfman said. “At the moment, there are no feasible plans to do so.”

What is the future of nuclear energy?

As the Fukushima nuclear water release continues its third phase and looks toward its 30-year release plan, scientists like Dorfman consider the overall effectiveness of nuclear power and its potential risks.

“The weight of evidence shows that due to the pace, scale and economics of the renewable evolution, all nuclear can do is make promises it just can’t keep,” Dorfman said.

Dorfman continued to explain how renewable energy will outstrip nuclear soon.

“Nuclear is quite simply just marginal,” Dorfman said. “In terms of cost, time, and do-ability — it’s renewable expansion in all sectors, energy efficiency and management, rapidly advancing storage technologies, grid modernization, interconnection and market innovation from supply to service provision that will power the global net-zero energy transition.”

As Nuclear wastewater disposal continues, organizations like the IAEA and NAML continue to debate the potential health impacts. https://universe.byu.edu/2023/11/14/fukushima-nuclear-power-plant-starts-third-round-of-wastewater-release-potentially-impacting-seafood-quality-in-u-s/

Mechanism for toxic radioactive water release sought

“What I find problematic is that TEPCO, the Japanese government and the IAEA are not addressing the long-term environmental impacts and the accumulation in the environment resulting from individual data. In the case of long-term releases, there is a concern about accumulation in the marine environment and concentration through the ecosystem, but this aspect is not being adequately evaluated.”

By JIANG XUEQING in Tokyo  2023-10-24  https://global.chinadaily.com.cn/a/202310/24/WS65372116a31090682a5ea51d.htmll

Experts urge long-term intl monitoring and participation of all stakeholders

Experts call for the establishment of a long-term international monitoring mechanism with substantive participation from stakeholders, as Japan and the International Atomic Energy Agency are both criticized for not addressing the long-term environmental impacts of the dumping of nuclear-contaminated water into the sea.

The IAEA is sending its team to Japan to continue its safety review of the release from the crippled Fukushima Daiichi Nuclear Power Plant.

Starting Tuesday, the IAEA will conduct a safety review of the activities carried out at the Fukushima plant to make sure these activities are consistent with the international safety standards, said Lydie Evrard, IAEA deputy director-general and head of the agency’s department of nuclear safety and security.

A report on the review is expected to be finalized by the end of 2023, she told a news conference in Tokyo on Monday.

Chinese Foreign Ministry spokesman Wang Wenbin on Oct 11 said the collection of marine samples near Fukushima, analysis by laboratories and comparison of those samples were carried out by the IAEA Secretariat under its bilateral arrangement with Japan. Therefore, he said, it falls short of an international monitoring arrangement with the full and substantive participation of all stakeholders.

“The international community requires the immediate establishment of an international monitoring arrangement with substantive participation of all stakeholders, including Japan’s neighboring countries, that will stay effective for the long haul,” Wang said, urging the IAEA to play its due role and take the responsibility of providing rigorous supervision on Japan’s discharge.

The key issue is how to establish an international monitoring mechanism for the real-time and long-term effective management of nuclear-contaminated water being discharged, said Zhang Yulai, vice-president of the Japan Institute of Nankai University.

Major challenge

“Information disclosure is a major challenge because the Japanese government and TEPCO share common interests, making genuine monitoring difficult,” he said.

There are also technical challenges, as certain radionuclides that the Advanced Liquid Processing System cannot remove still exist, he said.

Fukushima plant operator TEPCO announced pre-discharge test results on Thursday, showing that the third batch of nuclear-contaminated water to be released during Japan’s next round of ocean discharge contains seven radionuclides, namely tritium, carbon-14, cobalt-60, strontium-90, yttrium-90, iodine-129 and cesium-137. Among them, strontium-90 and yttrium-90 were not detectable before the second round of discharge.

The measured quantity of strontium is relatively low, but given its 29-year half-life, it will persist in the environment to a certain extent. Strontium is a significant radionuclide that tends to accumulate in bones when ingested by fish or humans, said Hideyuki Ban, a renowned Japanese nuclear expert and co-director of the Tokyo-based Citizens’ Nuclear Information Center.

“What concerns me is the lack of information about the measurement times and methods. I believe that rapid measurements may lack precision,” Ban said.

“What I find problematic is that TEPCO, the Japanese government and the IAEA are not addressing the long-term environmental impacts and the accumulation in the environment resulting from individual data. In the case of long-term releases, there is a concern about accumulation in the marine environment and concentration through the ecosystem, but this aspect is not being adequately evaluated.”

Many Japanese said they do not believe the data disclosed by TEPCO and the Japanese government.

Chiyo Oda, co-director of KOREUMI, also known as the Citizens’ Conference to Condemn Further Pollution of the Ocean, said those who have experienced the nuclear disaster have developed distrust in the government and TEPCO.

The promise not to release the water without first understanding the concerns of fishermen and citizens, as stated just before the release, has been disregarded. Though they have announced monitoring results immediately after the release, the data is not trustworthy, Oda said.

“It is evident that the marine environment will be contaminated over a long period of time, and there is potential for long-term impacts on human health,” she said. #nuclear #antinuclear #nuclearfree #NoNukes
