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

On 30 January 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).

This update on the daily monitoring by TEPCO of seawater near Fukushima Daiichi NPS indicates that the concentrations of all radionuclides (i.e. Cs-134, Cs-137, total Beta and H-3) were relatively stable from 20 to 26 January 2014 at the sampling points T-1 and T-2-1. The NRA also provided an update on the sea are monitoring results for radioactivity obtained from sea water samples taken at a distance of two to 200 kilometers from TEPCO's Fukushima Daiichi NPS.

A document released by the Japan's Ministry of Foreign Affairs also mentions the report submitted by Japan In December to the IAEA on events and highlights on the progress related to the recovery operations at the Fukushima Daiichi NPS.

TEPCO has also provided a document outlining some of the robotics that are being developed to assist in decontamination of the reactor buildings and translated a document detailing their technique to measure the height of the water level in the Unit 2 suppression chamber.
