Based on the instruction document on emergency countermeasures for safety
at Fukushima Daini Nuclear Power Station received from the Minister of 
Economy, Trade and Industry on April 21, we have summarized implementation 
status of emergency countermeasures for safety at Fukushima Daini Nuclear 
Power Station to prevent damages of reactor core and spent fuel, suppress 
discharge of radioactive materials and restore cooling function of reactor 
facility, even if three functions such as function of all facilities that 
supplies AC power, function of all facilities that cools reactor facility 
and function of all facilities that cools spent fuel pool by seawater are 
lost by tsunami and to maintain reactor cold shutdown, and reported to the 
Minister of Economy, Trade and Industry on May 20.
                                               (Announced on May 20, 2011)

After the submission of the report, to enhance flood prevention measures 
and to amend rounding of fractions when calculating load capacity in case 
of lost of all AC power supply, etc., we amended some part of the report 
and submitted it to the Minister of Economy, Trade and Industry today.
