On 24 September 2014, Japan provided the IAEA with an update to current information on radioactivity in seawater at TEPCO's Fukushima Daiichi Nuclear Power Station (NPS).
The update shows that all radionuclides (i.e. Cs-134, Cs-137, total Beta and H-3) have remained low and stable from 15 to 20 September 2014 at the sampling points T-1 and T-2-1. The NRA also 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.
Japan's NRA has also provided the Agency with a news release on an incident involving a crack in a connection valve between tanks for concentrated water that TEPCO has reported on 17 September 2014.?
