Press Release (Apr 02,2011)
Out flow of fluid containing radioactive materials to the ocean from areas near intake channel of Fukushima Daiichi Nuclear Power Station Unit 2

---

Today at around 9:30 am, we detected water containing radiation dose over 
1,000 mSv/h in the pit* where supply cables are stored near the intake 
channel of Unit 2. Furthermore, there was a crack about 20 cm on the 
concrete lateral of the pit, from where the water in the pit was out 
flowing. At around 12:20 pm, we reaffirmed the event at the scene.
We have implemented sampling of the water in the pit, together with the 
seawater in front of the bar screen near the pit. These samples were sent 
to Fukushima Daini Nuclear Power Station for analysis.
In addition to seawater sampling conducted in the coastal areas of 
Fukushima Daiichi/Daini Nuclear Power Station (sampling conducted at 4 
points), we have initiated additional seawater sampling at 3 points in the
areas 15 km offshore from the relevant power stations. Taking into account
the result of these monitoring, we are intending to conduct a 
comprehensive assessment.
Currently, we are preparing to block up the leakage by injecting concrete 
to the crack. Moreover, we will investigate the influx route of 
contaminated water in the pit and implement necessary measures to prevent 
such influx.
