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 7, Units 1 to 4 remain in a cold shutdown (please 
refer to the appendix). 
We will make our best efforts to stabilize each plant. 
 
○Regular inspection of monitoring posts 
  Among monitoring posts (7 in total), which are installed at site 
  boundary, we are implementing a regular inspection for those of No. 1 to 
  6 from July 29.
  In the period of inspection, although it is impossible to measure 
  radiation dose at inspected monitoring posts, we will continue monitoring
  and confirming data from remaining 6 ones.
  Inspection dates might be changed due to weather.

(Operation Results of Regular Inspection)
  No. 6: on July 29, from 9:31 am to 6:30 pm
   *No data change was observed before and after the inspection
  No. 1: from 9:31 am, August 2 to 2:30 pm, August 3
  No. 3: from 9:31 am to 6:00 pm, August 4
  No. 4: from 9:31 am to 5:40 pm, August 5
   *Slight changes in the data were confirmed before and after the 
    inspection. However, those changes are subject to the adjustments 
    within the range of measurement devices' allowable margin of errors and
    are not caused by changes in environmental radiation dose or detectors'
    troubles.
