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).
