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.                (March 11 previously announced)

At 7:15 am 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.
                                         (March 15 previously announced)

As of 4:00 pm on December 9, the reactors of Units 1 to 4 are in cold
