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).

 At approximately 10:01 am on May 27th, 2011, a fire broke out at the 
distribution panel for lighting at power supply room for High Pressure Core
Spray System on the 1st basement floor of reactor building annex of Unit 1 
which has been shutdown. At 10:04 am, workers of partner company 
extinguished the fire, and TEPCO's employee confirmed the fire had been 
extinguished. We reported the incident to the fire station at 10:08 am 
(previously announced on May 27).
Later, at 11:19 am, the fire station staff confirmed at the site that the 
fire had been extinguished. This incident has been judged as a small fire 
of building. 
 
As of 3:00 pm on May 27, 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.
