Due to the affect of tsunami accompanied by the earthquake on March 11, 
2011, the relevant events under the Act on Special Measures Concerning 
Nuclear Emergency Preparedness occurred at each of Units 1, 2 and 4 in 
Fukushima Daini Nuclear Power Station. On March 12 2011, the declaration 
of a Nuclear Emergency Situation was issued by the Prime Minister. 
After that, emergency response measures were taken such as restoring 
electric motors and recovering the function of residual heat removal pumps. 
Cold shut down has been achieved for each of the unit by March 15.  
Thereafter, those emergency response measures had been continuously taken, 
and also TEPCO endeavored to maintain stable cold shut down status of the 
plant, multiplexing power supply function and residual heat removal 
function. As a result, on December 26, Nuclear Emergency Situation was 
lifted by the Prime Minister, and TEPCO moved onto the phase to implement 
the post nuclear disaster incident measurement. 
Implementing those countermeasures, TEPCO has established the restoration 
plan based on the nuclear plant operator's anti- disaster measures 
operation plan. TEPCO submitted the plan to the Minister of Economy, Trade 
and Industry, and the governors of Fukushima prefecture, Naraha town, and 
Tomioka town on January 31, 2012. 
 
TEPCO will continue to restore facilities for the cold shut down of the 
plants etc based on this plan to improve the reliability further. 
 
We announce the plant status as of 3:00 pm today per the attachment 
(There are no updates from the previous announcement.).
