We, Tokyo Electric Power Company, received an instruction notice*1 
"Regarding the additional opinion of NISA for the analysis of reporting 
the results of evaluation of earthquake-proof safety of existing reactor 
facilities for power generation, referring to the new earthquake-proof 
standards established based on the Tohoku-Chihou- Taiheiyo-Oki Earthquake, 
2011 (Instruction)". As a consequence of the occurrence of Tohoku-Chihou-
Taiheiyou-Oki Earthquake, after which a huge crustal movement was observed, 
we have reviewed and summarized the Information regarding fault, which is 
necessary to take into consideration in the seismic design, which is 
necessary to review the possibility of eligibility to take into 
consideration in the seismic design of nuclear power station, for existing 
nuclear power station with existing survey and submitted to NISA on May 31, 
2011.
                       (Previously announced on April 29 and May 31, 2011)

On June 6, 2011, we received an additional instruction notice*2 regarding 
the above matter (Previously announced on June 6, 2011). Therefore, we 
conducted investigations on the amount of crustal movements and occurrence 
of earthquakes at the faults which we had evaluated that they need not to 
be considered for the seismic design. At the same time, we conducted ground 
reconnaissance and summarized a report regarding the faults of which we 
cannot deny the possibility that they fall into the faults which need to 
be considered for the seismic design and analyzed the influence upon the 
standard ground motion. Today we reported the results of our analysis to 
NISA.

                                                                       END

Attachment: Report regarding "Regarding the additional opinion of NISA for 
            the analysis of reporting the results of evaluation of 
            earthquake-proof safety of existing reactor facilities for 
            power generation, referring to the new earthquake-proof 
            standards established based on the Tohoku-Chihou- Taiheiyo-Oki 
            Earthquake, 2011 (additional instruction)" [Summary]

*2 Additional Instruction
  "Regarding the response to the addition of opinions upon considered by 
  NISA in relation to the report of the evaluation results on seismic 
  safety of existing nuclear power reactor facilities etc. in light of the 
  new Seismic Regulatory Guide based on the 2011 Tohoku District-Off the 
  Pacific Ocean Earthquake (additional instruction)"
