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

On 27 November 2013, 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).

This update states that the concentrations of Cs-134, Cs-137, total Beta and H-3 were relatively stable from 18 to 24 November 2013 at the nuclear power station.

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.

To provide and track specific details on the transfer of fuel from the spent fuel from Unit 4 of the Fukushima Daiichi NPS that commenced on 18 November 2013, a new section on the TEPCO website is now available.

TEPCO has also provided information on the review that was undertaken following the operation of fuel removal from the Unit 4 spent fuel pool in a document dated 25 November 2013 titled Work Procedure Review Following Unused Fuel Removal at Fukushima Daiichi NPS Unit 4. Details are available here.

A series of photos and videos of the transfer process of the unused fuel removal at the Fukushima Daiichi NPS Unit 4 can be accessed at the following links:
