On March 11th 2011, turbines and reactors of Fukushima Daini Nuclear Power 
Station Units 1 to 4 (Boiling Water Reactors, rated output 1,100 Megawatts) 
that we had been constantly operating at rated thermal output were 
automatically shut down at 2:48 pm due to the Tohoku-Chihou-Taiheiyou-Oki 
Earthquake (previously announced on March 11th). 
 
At 7:15 pm on March 15th, the reactor of Unit 4 achieved cold shutdown. As
