Tokyo has addressed key radioactivity characterisation issue in updates, says agency The water has been stored in tanks onsite, but space is running out. Courtesy Dean Calma/IAEA. An International Atomic Energy Agency task force set up last year to review the safety of Japan’s policy to handle treated water stored at the Fukushima-Daiichi nuclear station has carried out a new mission to the country to review its updated technical plans for the water discharge.

The updates – made in part due to feedback provided during an ongoing IAEA safety review process – include changes to the radiological environmental impact assessment before the discharge and the associated monitoring programmes. They also include the key issue of characterising the radioactivity in the water.

Japan announced in April 2021 that it planned to discharge more than 1.25 million cubic metres of treated water stored at the station by discharging it into the sea. The plan was approved by the nuclear regulator earlier this year.

The IAEA’s task force, a group of IAEA specialists and external experts from 11 countries, are conducting a multi-year review of the plan’s safety.

As part of its second mission the task force met in Tokyo this week with Tokyo Electric Power Company (Tepco), operator of Fukushima-Daiichi, and the Ministry of Economy, Trade and Industry (Meti).

The International Atomic Energy Agency (IAEA) has said that a team of experts will visit Japan to observe the collection and treatment of marine samples from the sea near the Fukushima Daiichi NPP. The mission aims to verify the quality of sample collection procedures and analytical methods used by Japanese laboratories performing marine environmental radioactivity monitoring.

In their latest annual strategic progress report, experts from Japan’s Nuclear Damage Compensation and Decommissioning Facilitation Corporation (NDF – part of Tokyo Electric Power Corporation - Tepco) proposed that a massive concrete reservoir should be built and filled with water to completely enclose one of the Fukushima Daiichi reactor buildings.

Tokyo Electric Power Company Holdings (Tepco) now estimates that tanks containing treated water at the Fukushima Daiichi NPP are likely to reach capacity around the autumn of 2023, somewhat later than the initial prediction of spring 2023, after the accumulation of radioactive water slowed down in fiscal 2021, Kyodo reported. This provides more time to deal with any obstacles to plans for the discharge of the treated water into the sea from next spring.

Authorities say there is ‘no practical alternative’ Water storage tanks at the Fukushima-Daiichi nuclear power station site. IAEA/Dean Calma. Japan’s Nuclear Regulation Authority (NRA) has granted an initial approval for Tokyo Electric Power Company’s (Tepco) plan to release water from the destroyed Fukushima-Daiichi nuclear power station into sea, saying there are no safety issues.

The NRA plans to make a decision on final approval after a one-month public comment period, an NRA official was quoted as saying by local media.

In April 2021 Japan announced its policy to gradually discharge more than 1.25 million cubic metres of treated water into the sea, subject to approval from the NRA, an independent regulatory body.

It asked for the International Atomic Energy Agency’s assistance to help ensure the project’s implementation. Japanese authorities said there was no practical alternative to releasing the water as storage space ran out. They said there was no risk to human health and that operating nuclear plants around the world release similar water every day.
