   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 November 6th to November 12th, 2008. 

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


   < Reports from November 6 to November 12, 2008 >


  ○ Other Findings

   • Information on Nonconformances (those related to: the Chuetsu-Oki Earthquake; 
     Grades As, A, B, C, D; and non-graded)

      * Numbers were corrected to reflect nonconformance incidents that had been 
        identified as not related to the Chuetsu-Oki Earthquake (12 cases) and 
        that had been double-counted (1 case). 

   • Visual inspection was conducted for stack radiation monitor sampling pipes of Unit 
     No.1 and Unit No.3 after removing insulation. As a result of the inspection, damage 
     was found on an intake side pipe of sampling pump of Unit No.3, and a misalignment 
     was found on the joint of discharge side pipes of sampling pump of Unit No.1. These 
     incidents did not lead to any radiological impact to the environment. Additionally, 
     visual inspection was conducted for stack radiation monitor sampling pipes of Unit 
     No.2 and Unit No. 4 after removing insulation, and no additional damage was found. 

     Subsequently, visual inspection was conducted for stack radiation monitor sampling 
     pipes of Unit No.5, Unit No.6 and Unit No.7 from December 3rd to December 10th, 2008 
     after removing insulation, and no additional damage was found. Detailed inspection 
     will be continued as well as root cause analysis of damages of Unit No.1 and Unit 
     No.3.
