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

On 3 June 2014, Japan provided the IAEA with information that TEPCO has discharged 641 tonnes of groundwater at the Fukushima Daiichi Nuclear Power Station (NPS) to the ocean on 27 May 2014 by means of the groundwater bypass system.

The update further provides measurements of seawater obtained at the sampling points T-1 and T-2-1 on 25 to 31 May 2014. The groundwater discharge had no recognizable effect in these measurement.

The NRA also provided an update of 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.
