19 November 2013	The Government of Japan's Nuclear Regulation Authority (NRA) announced on 19 November 2013 the NRA's enhanced sea area monitoring measures in the area within a 30 kilometre radius from the Tokyo Electric Power Company's (TEPCO) Fukushima Daiichi Nuclear Power Station, as well as the initiation of a comparative analysis of the seawater monitoring data gathered by TEPCO and the NRA. The enhanced measures include additional monthly measurements (commencing 21 November 2013) and the establishment of seven additional sampling points, where radionuclides will be analysed, including Cs-134 (detection limit: 0.001Bq/L), Cs-137 (detection limit: 0.001Bq/L), Sr-90 (detection limit: 0.01Bq/L), H-3 (detection limit: 0.5Bq/L), K-40 (detection limit: 1Bq/L). The NRA had already been undertaking seawater monitoring beyond a 30 kilometre radius from TEPCO's Fukushima Daiichi Nuclear Power Station. Read more >
15 November 2013	The Japanese Nuclear Regulation Authority (NRA) today provided the IAEA with a news release on its recent actions related to the fuel removal from the reactor building of Unit 4 of the Fukushima Daiichi Nuclear Power Station, as well as a progress report from TEPCO also related to the fuel removal at this Unit.
