On March 11 2011, Fukushima Daini Nuclear Power Station Units 1 to 4
(Boiling Water Reactors, rated output 1,100 Megawatts each) that we had
been operating at rated thermal output shutdown automatically 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 a cold shutdown. As
a result, all the Units of Fukushima Daini Nuclear Power Station achieved
the status of cold shutdown (previously announced on March 15). 

As of 3:00 pm on August 2, Units 1 to 4 remain in a cold shutdown (please
refer to the appendix). 
We will make our best efforts to stabilize each plant.

 ○Restoration of residual heat removal system (A) of Unit 4 
 With regard to the residual heat removal system (A) of Unit 4, which we 
 continued to work on for restoration, we conducted test run for it from 
 11:54 am to 12:24 pm on August 2 and since then it has kept in standby 
 condition. 

 ○Regular inspection of monitoring post 
 Among monitoring post (total of 7), which are installed at site boundary, 
 we are implementing regular inspection for No. 1 - 6 (1 monitoring post 
 per day) from July 29 to August 8.
 In the period of inspection, although it is unable to measure radiation 
 dose by such monitoring post, we will continue to measure and confirm the 
 data by using remainder of 6 monitoring post.
 Inspection date might be changed due to the weather.

 (Operation Results of Regular Inspection)
  No. 6: July 29, 9:31 am - 6:30 pm in regular inspection
  *No significant changes in the data were confirmed before and after the 
   inspection of monitoring posts.
