  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 August 7th to August 20th, 2008. 

 ○ Incidents Information (relating to the Chuetsu-Oki Earthquake)  
 < Reports from August 7 to August 20, 2008 >  
 ○ Other Findings 
   • Unit No.4
     The casing for the low-pressure turbine (C) has been opened and internal inspection 
     of the turbine has been conducted since July 22nd, 2008. 
     On August 19th, wears with a maximum length of about 1mm have been found on the tip 
     of rotor blades (from stages 9 to 11 of the shroud on generator-side). Wears with a 
     maximum length of about 1mm have been found on stators, presumably caused by impact 
     with rotors.
     The location and size of wears 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.
