On March 11 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 11).

At 7:15 pm on March 15, 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 15).

As of 3:00 pm on June 1, the reactors of Unit 1 to 4 are in cold shutdown 
(please refer to the appendix). We continue to make our endeavors to 
stabilize each plant.
