  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 17th to July 23rd, 2008. 

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


 < Reports from July 17 to July 23, 2008 >


 ○ Other Findings 

  • Unit No.6 
   Visual inspection was conducted for forks of 260 rotor blades on the 16th stage of 
   the low-pressure turbine (C) (130 blades each on generator-side and turbine-side). 
   As a result, no damage was found. Additionally, non-destructive investigation resulted 
   in indications on the forks of 4 rotor blades on the turbine-side. Indication was not 
   found on the generator-side. 

  • While confirming contamination of damaged pallets in the solid waste storage warehouse 
    to have them stored on site, a minuscule amount of radioactive material -- about 1.4 
    Becquerel/cm2 -- was found on one of the pallets on July 17, 2008. The pallet has been 
    covered by a sheet and is stored in the solid waste storage warehouse.
