On 1 February 2025, Japan provided the IAEA with a copy of a?report?on the discharge record and the seawater monitoring results at the Fukushima Daiichi Nuclear Power Station during October, which the Ministry of Foreign Affairs has sent to all international Missions in Japan.
The report contains information on discharges from the subdrain and groundwater drain systems, as well as on groundwater bypassing conducted during the month of October. In both cases, in advance of the action, TEPCO analyzes the quality of the groundwater to be discharged and announces the results. These results confirm that the radiation level of sampled water are substantially below the operational targets set by TEPCO.
