Fukushima Daiichi NPS Prompt Report 2013

Fukushima Daiichi NPS Prompt Report (Apr 05, 2013)Water Leak from the Underground Reservoir No.2 in Fukushima Daiichi Nuclear Power Station

On April 3, order of 101 (Bq/cm3) of radioactive concentration was detected as a result of a water quality analysis of the water between the outermost sheet (bentonite sheet) of three layered sheets and the ground in the underground reservoir No.2.

Therefore, we conducted a water quality analysis of the water between the outermost sheet (bentonite sheet) and the inner sheet (two layered water shielding sheet) today (April 5) and detected approximately 106 (Bq/cm3) of radioactive concentration.

We will conduct additional water quality analysis tomorrow (April 6).

Now we are investigating this incident.
