This is follow-up information regarding the water leak from a drain valve of a tank dike in the H4 area in Fukushima Daiichi NPS.
As a result of confirmation on the site conditions, a puddle of approx. 1-2cm was found inside the dike, and a puddle of approx. 3m×3m×1cm was found outside of the drain valve of the dike.
There is no trace of water having flowed into a public drainage ditch, etc. from the puddle found outside of the drain valve of the dike. Therefore, we consider that the water has not flowed out into the sea.
We will conduct sampling on the water thus found.
