Fukushima Daiichi NPS Prompt Report 2013

Today (June 5), at around 12:15PM, our corporate company worker found water leaking at a pace of 1 drop per 3-4 seconds from the joint between the second and third layer (counting from the bottom) steel plates of the G6-1 Area No.9 tank side wall during patrol.

The leaking water has not reached on the concrete basement inside the dike, since we have put an absorber on the spot.

The No.9 tank has been isolated (water transfer has been stopped) from the other seventeen G6-1 area tanks at 12:20PM. Furthermore, we will tighten the joint.

The water transfer from the underground reservoir No.6 to the G6 area has also been stopped at 12:45PM for just in case.

We are currently investigating the cause of the issue.
No significant fluctuation was found with the monitoring post readings.
