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

On 12 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 2 to 8 October 2014 at the sampling points T-1 and T-2-1.

The update also reports on a recent visit by experts from the IAEA Environment Laboratory in Monaco  who presented the results of an inter-laboratory comparison study of samples collected in September 2014 in the coastal waters near the Fukushima Daiichi NPS. On 5 and 6 November 2014, the IAEA experts together with NRA staff collected water samples from the sea at the same five locations where water samples were previously collected. More information can be found here.

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.
