  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 July 3rd to July 9th, 2008. 

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


 < Reports from July 3 to July 9, 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 an addition of a nonconformance incident.

   • Unit No.3 
     The casing for the low-pressure turbine (C) has been opened and internal inspection 
     of the turbine has been conducted since June 30, 2008. 
     On July 4, wears with a maximum length of about 2mm have been found on the tip of 
     rotor blades (from stages 9 to 11 of the shroud). Wears with a maximum length of 
     about 1mm have been found on stators, presumably caused by impact with rotors.
     The location and size of wear of rotors and stators that were found this time are 
     similar to those confirmed in low-pressure turbine (A) and (B). 
     Wears on rotors and stators will be repaired. If similar wears were to be found in 
     other units, we will notify the fact through this weekly report.
