At around 12:30 pm today, a worker, who was in charge of blockage work of 
the pit*, has found water was flowing into the pit near the water intake 
canal of Unit 3 through the pipe for electrical cables.
Now we are investigating the possibility of the leakage of radioactive 
water off the site and sampling water inside the pit and sea water of 
water intake canal of Unit 3 and analyzing at Fukushima Daini Nuclear 
Power Station.

We are planning to take a countermeasure to stop the inflow of water into 
the pit.

As a result of investigation, outflow of the water from the pit to sea was 
found at around 4:05pm.

We inserted fabrics to the conduit line leading to the pit and filled 
concrete inside the pit. After that, we confirmed that outflow was stopped 
at 6:45pm today. 
We will monitor the condition of water stop and, will also investigate sea 
water sampled at the water intake canal of Unit3 as well as the route of 
inflow and outflow and their condition.
