Japan's Reports on Conditions at TEPCO's Fukushima Daiichi Nuclear Power Station

On 4 November 2014, the Nuclear Regulation Authority (NRA) of Japan provided the IAEA with an update on radioactivity in seawater at TEPCO's Fukushima Daiichi Nuclear Power Station (NPS).

The update on the daily monitoring by TEPCO of seawater near the Fukushima Daiichi NPS indicates that the concentrations of all radionuclides (i.e. Cs-134, Cs-137, total Beta and H-3) remained low and stable from 26 October to 2 November 2014 at the sampling points T-1 and T-2-1.

In addition, the NRA provided an update on sea area monitoring results for radioactivity obtained from sea water samples taken at a distance of 2 to 200 kilometres from TEPCO's Fukushima Daiichi NPS.

Additionally, the NRA provided the IAEA with an interim report on ongoing mid- and long-tem analysis of the TEPCO Fukushima Daiichi NPS accident. It covers various issues including those raised in the reports by the National Diet Investigation Commission, the Government Investigation Committee, the Non-governmental Investigation Committee, and TEPCO Investigation Committee. This report is the first one and the NRA will continue to submit additional reports based on the progress of the investigation and review.
