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 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 (previously announced on March 15).  

As of 3:00 pm on August 31, the reactors of Units 1 to 4 are in cold 
shutdown (please refer to the appendix). We will continue to make our 
endeavors to further stabilize each plant of cold shutdown.

 At 11:53 am on August 31, Unit 3 emergency diesel generator (A) was 
 restored and in standby condition.
