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).

Tepco Holdings Co Ltd and Hitachi Zosen Co Ltd (Hitachi Shipbuilding) have set up a joint venture to establish a plant for manufacturing various core products necessary for decommissioning, such as used fuel casks and debris storage containers. The new company, Toso Mirai Manufacturing, was established in April. In order to achieve "a balance between reconstruction and decommissioning”, Tepco is bringing together decommissioning industries in the Hamadori area of Fukushima Prefecture, to develop and manufacture core technologies and products for decommissioning.

Tokyo Electric Power Company Holdings (Tepco) says it will have to delay to late 2023 the removal of melted nuclear fuel debris from the unit 2 reactor at the Fukushima Daiichi NPP while adjustments are made to the robotic arms which will undertake the work. Tepco had initially planned to start the debris removal on a trial basis in 2021 but postponed it to 2022 in face of the coronavirus pandemic.
