Nonconformances Found in the Inspection and Restoration Works Performed 
after the Niigata-Chuetsu-Oki Earthquake

 Based on the "Public Announcement Regarding Nonconformance Found in the 
 Inspection and Restoration Works Performed after the Niigata-Chuetsu-Oki 
 Earthquake," the Tokyo Electric Power Company, Incorporated (TEPCO) 
 provides this announcement containing incidents information reported from 
 December 2 to December 8, 2010. 

 ◇ Incidents Information (relating to the Chuetsu-Oki Earthquake)


    <Reports from December 2 to December 8, 2010>


 ◇ Other Findings
   - Information on Nonconformances (those related to: the Chuetsu-Oki 
     Earthquake; Grades GI, GII, GIII; and non-graded) 
     (including nonconformances related to: the Chuetsu-Oki Earthquake; 
     Grades As, A, B, C, D; and non-graded) 


    * By close reexamination of past nonconformance incidents, 1 of them 
      is identified as not related to the Chuetsu-Oki Earthquake, so the 
      total number of them has been corrected. 

   - We are making every effort to carry on inspections and restoration 
     works at the Kashiwazaki-Kariwa Nuclear Power Station after the 
     Niigata-Chuetsu-Oki Earthquake. In addition to this, we will implement 
     the inspection of heating ventilation and air-conditioning system 
     ducts which are placed inside and outside of Unit 2, Unit 3 and Unit 
     4, in the light of fact that air leakage from outdoor air-conditioning 
     duct (main body) and penetration part of outdoor air-conditioning duct 
     building was found at the Fukushima Daiichi Nuclear Power Station. We 
     will perform the inspection for about 2 months from December 13, 2010.
