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.

On 14 November 2013, the Japanese Nuclear Regulation Authority (NRA) issued a news release in which it detailed requirements that NRA provided TEPCO for undertaking fuel removal from the spent fuel storage pools in reactor buildings to the Common Spent Fuel Pool, under the Act on Regulation of Nuclear Source Material, Nuclear Fuel Material and Nuclear Reactors. Details of the implementation plan can be accessed at NRA Actions Towards TEPCO Fuel Removal.

On 13 November 2013, the Japanese Nuclear Regulation Authority (NRA) provided the IAEA an update on radioactivity in seawater at TEPCO's Fukushima Daiichi Nuclear Power Station (NPS).

The report notes that on 9 November 2013 TEPCO found contaminated water was leaking from the dike surrounding H6 Tank Area in Fukushima Daiichi Nuclear Power Station. Information on this leakage can be found on Seawater Monitoring Near Fukushima Daiichi NPS.

The NRA report also states that the concentrations of Cs-134, Cs-137, total Beta, and H-3 were relatively stable from 4 to 10 November 2013 at the nuclear power station - Seawater Monitoring Near Fukushima Daiichi NPS.

In addition, the NRA provided an update on the monitoring report of sea area radioactivity obtained from samples taken in the vicinity of TEPCO's Fukushima Daiichi NPS and in the open sea.
