  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 May 29th to June 4th, 2008.  


 ○ Incidents Information (relating to the Chuetsu-Oki Earthquake)  
< Reports from May 29 to June 4, 2008 >  
 ○ Other Findings 
  • Unit No.6 
    Visual inspection and non-destructive inspection for forks of rotor blades on the 
    14th stage of the low-pressure turbine (A), (B) and (C) and forks of rotor blades 
    on the 15th and 16th stage of the low-pressure turbine (B) are going on (announced 
    on May 15th, 2008).
    Visual inspection was conducted for forks of 304 rotor blades on the 14th stage of 
    the low-pressure turbine (B) (152 blades each on generator-side and turbine-side).
    As a result, no damage was found.  Additionally, non-destructive investigation 
    resulted in indications in the forks of 28 rotor blades on the generator-side and 
    63 rotor blades on the turbine-side.  
    Subsequently, investigation on the cause of the damages and indications will be 
    continued as well as visual and non-destructive inspection for forks of rotor blades 
    on the 14th stage of the low-pressure turbine (A) and (C) and forks of rotor blades 
    on the 15th and 16th stages of the low-pressure turbine (B), and non-destructive 
    inspection for fixtures of rotor fork of the 14th stage of low-pressure turbine.
