Berlin, April 29, 2022 – The International Atomic Energy Agency (IAEA) announced on April 29 that it will continue its investigation into the discharge into the ocean of treated water containing tritium from TEPCO’s Fukushima No. 1 nuclear power plant. On April 29, the International Atomic Energy Agency (IAEA) compiled the first report by a team of investigators to verify the safety of the discharge of treated water containing tritium from TEPCO’s Fukushima Daiichi Nuclear Power Plant. The report noted that, based on TEPCO’s analysis of the impact of radiation on the human body if the treated water were to be released, “it has been confirmed that the level of radiation is significantly smaller than that set by the Japanese regulatory authorities. However, he also explained that a final decision on safety will be announced before the release of the water. He indicated that he would not draw any conclusions for the time being, but would continue his investigation.

 The survey team visited Japan in February, inspected the Fukushima Daiichi Nuclear Power Plant, and held hearings with related ministries and agencies and TEPCO. The report will be released two months after each survey that will be conducted before the release of the water in the future. TEPCO has set the timing of when the tanks storing the treated water will be full at around the summer or fall of 2023.
