Fukushima Daiichi NPS Prompt Report 2013

Fukushima Daiichi NPS Prompt Report (Sep 15, 2013)Water Leak at a Tank in the H4 area in Fukushima Daiichi Nuclear Power Station (Follow-up Information 42)

We would like to announce the results of samples (the south water outlet and the drainage channel) concerning the water leak at a tank in the H4 area in Fukushima Daiichi Nuclear Power Station (sampled on September 14).

The result of all β at the point B-3 (in front of the junction of the drainage channel C) (where the result of all β has been increasing) was 4000Bq/L, and this is higher than the previous result (3000Bq/L). We observed no remarkable changes at other points.

The sample obtained at the point B-3 (in front of the junction of the drainage channel C) was colored with mud, therefore we have analyzed the filtrate after the filtration treatment.

We will continue analyzing and monitoring the situation.

For the past sampling results, please refer to the following page on our website:
