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 
a result, all reactors of Units 1 to 4 at Fukushima Daini Nuclear Power 
Station achieved cold shutdown (previously announced on March 15th).  

As of 4:00 pm on April 22nd, the reactors of Unit 1 to 4 are in cold 
shutdown (please refer to the appendix). We continue to make our endeavors
