Due to the Tsunami generated by Tohoku-Chihou-Taiheiyou-Oki Earthquake 
which occurred on March 11th 2011, TEPCO's facilities including our nuclear 
power stations have been severely damaged, released radioactive materials. 
We deeply apologize for the anxiety and inconvenience caused to local 
residents near the site, residents of Fukushima prefecture and throughout 
the entire society.
We will enlist cooperation from the government, each ministries and local 
government, with a strong association, we will put all our efforts toward 
breaking the deadlock.

We received the Order from Nuclear and Industrial Safety Agency that 
requires conducting "enforcement of emergency countermeasures for safety at 
Fukushima Daini Nuclear Power Station".
In our opinion, following this Order, we will consult on necessary safety 
countermeasures promptly, and report the results to Nuclear and Industrial 
Safety Agency.
 
"Order to conduct enforcement of emergency countermeasures for safety at 
Fukushima Daini Nuclear Power Station (Order)"

                                          20th Release of April 20th, 2011
                                      Nuclear and Industrial Safety Agency

Regarding the emergency countermeasures for safety, Nuclear and Industrial 
Safety Agency (NISA) have ordered enforcement of emergency countermeasures 
for safety to the Nuclear Power Station other than Fukushima Daiich Nuclear 
Power Station and Fukushima Daini Nuclear Power Station. The Order is based 
on the "order to conduct enforcement of emergency countermeasures for 
safety at Fukushima Daiich Nuclear Power Station and Fukushima Daini 
Nuclear Power Station" (dated March 28th, 2011; 7th Release of March 28th, 
2011 NISA).
Based on the situation of cold shutdown at Fukushima Daini Nuclear Power 
Station, we will give an order to the site to conduct enforcement of 
emergency countermeasures for safety.

Enforcement of emergency countermeasures for safety is intended to resume 
cooling feature at reactor in the situation of power outage due to Tsunami, 
with limiting released radioactive materials.
The proceeding of this enforcement go through the following steps, TEPCO 
conduct enforcement of emergency countermeasures and NISA confirm by 
inspection to prevent core damage caused by loss of power due to Tsunami. 
This will lead to prevent nuclear disaster.

Therefore, we demand TEPCO to conduct enforcement of emergency 
countermeasures below immediately, following the regulations dated March 30, 
2011 laying down safety regulation for maintenance regarding installation 
and operation of commercial power reactor to maintain Reactor Facility in 
cases where Tsunami occurs.
In the meantime, NISA ask TEPCO to report implementation status to keep 
reactor cold shutdown by May 20th, 2011. 

Note:
TEPCO should take following emergency countermeasures for safety 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.

1.Implementation of emergency inspection
 Implementation of emergency inspection of equipments and facilities for 
 emergency response caused by tsunami
2.Implementation of review and training on emergency response plan
 Implementation of review and training on emergency response plan that 
 assumes losses of 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
3.Securing of power source in emergencies
 Securing of backup power source which can supply necessary power agilely 
 in case any power sources in Fukushima Daini Nuclear Power Station are 
 lost and any emergency power sources cannot be secured
4.Securing of definitive heat removal function in emergencies
 Preparation of restoration countermeasures of agile heat removal function 
 that assumes loss of seawater system facility or its function
5.Securing of cooling of spent fuel pool in emergencies
 Implementation of countermeasures to supply cooling water agilely in case 
 of stoppage of cooling of spent fuel pool and normal water supply to spent 
 fuel pool in Fukushima Daini Nuclear Power Station
6.Implementation of immediate countermeasures taken in consideration of the 
 configuration of Fukushima Daini Nuclear Power Station
