At around 10:28 am on January 10, 2012, at the concentrated water tank of
water desalination (Reverse Osmosis Membrane) at Fukushima Daiichi Nuclear 
Power Station, our employee found water dripping from the packing at the 
base of the concentrated water storage tank at the rate of approximately a 
drop per second and also found accumulated water on the concrete where the 
tank is mounted.
The amount of leakage is estimated to be approximately 10 liters. We 
re-torqued the bolt at the joint of the tank, and confirmed that the water 
dripping had stopped at around 12:35 pm on the same day.
In addition, in order to prevent the water leakage from spreading, we 
stacked sand bags around the accumulated water.

Regarding this matter, we received a directive titled "Action in the event 
of water or radioactive material leakage from the storage tank of water 
desalination at Fukushima Daiichi Nuclear Power Station" from the Nuclear 
and Industrial Safety Agency (NISA). 
Based on this directive, we will take action to resolve this matter and 
report to NISA.

                                                                       END
