IWAKI, Japan — A member of the International Atomic Energy Agency team visiting Fukushima for its first marine sampling since the Fukushima Daiichi nuclear power plant started releasing treated radioactive wastewater into the sea said Thursday he does not expect any rise in radiation levels in the fish caught in the regional seas.
The IAEA team watched flounder and other popular kinds of fish being caught off the coast earlier Thursday and brought on boats to the Hisanohama port in southern Fukushima for an auction.
“I can say that we don’t expect to see any change starting in the fish,” said Paul McGinnity, an IAEA marine radiology scientist.
A small rise in the levels of tritium, which cannot be removed from the Fukushima Daiichi wastewater by the plant’s treatment system called ALPS, is possible in locations close to the discharge points, but the levels of radioactivity are expected to be similar to those measured before the discharge last year, he said.
Fukushima Daiichi started releasing wastewater into the sea on Aug. 24. The release, which is expected to continue for decades, has been strongly opposed by fishing groups and neighboring countries including South Korea, where hundreds of people have protested.
China immediately banned all imports of Japanese seafood the day the release began, badly hurting Japanese seafood producers, processors and exporters, and Russia recently joined China in the trade restrictions.
The IAEA has reviewed the safety of the wastewater release and concluded in July that if carried out as planned, it would have a negligible impact on the environment, marine life and human health.
During the Oct. 16-23 visit, the IAEA team also inspected the collection and processing of seawater and marine sediment near the plant, which suffered triple meltdowns following the March 2011 earthquake and tsunami.
The IAEA’s visit is significant not only because it is the first since the discharge began but also since the IAEA will be able to see firsthand how the fish is sampled and packed, McGinnity said. This will help them better evaluate the results, not just from laboratory testing and data analysis, he said.
IAEA selected six species of fish — olive flounder, crimson sea bream, redwing searobin, Japanese jack mackerel, silver croaker and vermiculated puffer fish — because they are known to have higher levels of radioactivity than other species due to the areas they tend to move around in, McGinnity said.
The Japanese government asked the IAEA to conduct the environmental and fish sampling to build confidence about the data that Japan provides amid skepticism in some IAEA member states, McGinnity said without identifying which countries.
The sample collection team includes two staff from the IAEA Marine Environment Laboratories in Monaco, as well as experts from laboratories in China, South Korea and Canada.
The fish collected Thursday were to be shipped to a Fisheries Agency laboratory in Chiba, near Tokyo, where the IAEA team will inspect them on Friday.
They will send identical samples to about a dozen participating laboratories, including in Japan, China, South Korea and Canada, for comparison and analysis of radioactivity and evaluation, the IAEA said.
The sampling work will be followed by a separate IAEA task force that will review the safety of the treated radioactive water.
Japan’s government has set up a relief fund to help find new markets and reduce the impact of China’s seafood ban. Measures include the temporary purchase, freezing and storage of seafood and promotion of seafood sales at home.
TEPCO and the government say discharging the water into the sea is unavoidable because the tanks will reach their 1.37 million-ton capacity next year and space at the plant will be needed for its decommissioning, which is expected to take decades, if it is achievable at all.
They say the water is treated to reduce radioactive materials to safe levels, and then is diluted with seawater by hundreds of times to make it much safer than international standards. Some experts say such long-term release of low-dose radioactivity is unprecedented and requires close monitoring.

Third release of treated water from Japan’s damaged Fukushima nuclear plant ends safely

TOKYO — 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 said Monday, 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 Aug. 24 and finished releasing the third 7,800-ton batch on Monday. The process is expected to take decades.
The discharges have been strongly opposed by fishing groups and neighboring countries including China, which banned all imports of Japanese seafood, badly hurting Japanese producers and exporters of scallops and other seafood.
The plant’s operator, Tokyo Electric Power Company Holdings, said the third release, like the two previous ones, went smoothly and marine samples tested by it and the government showed that levels of all selected radionuclides were far lower than international safety standards.
Japanese Prime Minister Fumio Kishida, in a meeting last Friday with Chinese President Xi Jinping on the sidelines of the Asia Pacific Economic Cooperation summit in San Francisco, asked China to immediately lift the seafood ban but achieved only a vague agreement to “find ways to resolve the dispute through meetings and dialogue in a constructive manner.”
The two sides will convene a meeting of scientific experts to discuss the release but there was no timetable for a possible lifting of the ban, Kishida said.
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.
The wastewater is treated to remove as much radioactivity as possible to meet legally releasable standards and then greatly diluted with seawater before it is discharged. 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 1,000 storage tanks at the Fukushima plant because of its continued production of wastewater, though 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.
