On December 12, 2011, we received the directive document* from NISA 
"Regarding the revision of safety regulation based upon the evaluation 
result of the facility management plan of Fukushima Daiichi Nuclear Power 
Plant, Tokyo Electric Power Company (Direction)*1".
(Previously announced on December 12, 2011)

On December 13, 2011, we submitted the application for the amendment to the 
Safety Regulations for Nuclear Reactor Facilities *2 of Fukushima Daiichi 
Nuclear Power Plant to NISA, in accordance with the direction.

The application summaries of the amendment to the Safety Regulations for 
Nuclear Reactor Facilities are as follows.

○It prescribes the operating and maintenance management of the following 
  facilities to make sure of the preservation management of the facilities 
  in conjunction with the circulating injection cooling system, and 
  prescribes an organization and duties, inspection, record and report etc. 
  to manage these systems.

 (1) The water injection system for RPV and PCV
 (2) The function to prevent the hydrogen explosion in PCV
 (3) Spent fuel pools etc.
 (4) The boric acid water injection system for RPV and PCV
 (5) High-level radioactive contaminated water processing equipment, 
     Retention facilities (tanks etc.), Storage facilities for abolished 
     sludge, Storage facilities for used cesium adsorption tower and 
     Associated facilities (transportation pipe, transportation pump etc.)
 (6) The buildings of retaining (including the case of accumulating) high-
     level radioactive contaminated water
 (7) Electric power system
                                (Previously announced on December 13, 2011)

After the review by the government, we received the approval for the 
amendment application for the safety regulations for nuclear reactor 
facilities of Fukushima Daiichi Nuclear Power Station by The Minister of 
Economy, Trade and Industry today.

                                                                        End

*2: Safety regulations for nuclear reactor facilities 
As per Article 37 Clause 1 of the Law on the Regulation of Nuclear Source 
Material, Nuclear Fuel Material and Reactors, this sets forth the basic 
matters for person who establishes the nuclear reactor to safely operate 
the nuclear power station (operation management, fuel management, radiation 
management, emergency procedures, etc.) and approved by the government.
