Japan's Nuclear Regulation Authority (NRA) has ordered plant operator Tokyo Electric Power Company (TEPCO) to urgently assess the risks of a possible collapse at unit 1 of the crippled Fukushima Daiichi NPP, and to formulate emergency measures as soon as possible to avoid any radioactive leakage. Videos taken during a robotic probe in March showed that the pedestal of unit 1’s containment vessel, the main supporting structure directly under its core, was severely damaged. The underwater robot found the concrete wall was missing in over half of the pedestal, measuring five metres in internal diameter, leaving the reinforcing bar exposed.

Japan’s Tokyo Electric Power Company (TEPCO), the operator of the Fukushima Daiichi Nuclear Power Station (NPS), has demonstrated its capabilities for accurate and precise measurements of the radionuclides present in the treated water stored on site, according to the International Atomic Energy Agency’s (IAEA’s) latest report covering its independent sampling and analysis work. This is part of its ongoing review to assess the safety related aspects of Japan’s plan to release the treated water from the Fukushima Daiichi NPS into the sea. In line with relevant IAEA international safety standards, Tepco is required to monitor the characteristics and activity of the treated water in order to accurately evaluate public exposure that will result from the discharge and to comply with its national regulatory authorisation.

The International Atomic Energy Agency (IAEA) Task Force assessing the safety of Japan’s planned discharge of treated water from the Fukushima Daiichi Nuclear Power Station has issued its fifth report. This is part of a series to be released under the IAEA’s multi-year safety review of the proposed Advanced Liquid Processing System (ALPS) treated water discharge. It focuses on Japan’s domestic regulatory review of the water release and includes observations of the Task Force mission to assess Japan’s Nuclear Regulation Authority (NRA) activities, which took place in January.

An International Atomic Energy Agency (IAEA) task force reviewing the safety of Japan's plan to discharge treated water from the damaged Fukushima Daiichi nuclear power plant into the sea has released its fourth report. The report compiles the findings from the task force's second safety review mission to Japan, held in November 2022.

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).
