  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 June 5th to June 11th, 2008.  

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


< Reports from June 5 to June 11, 2008 >


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


  • Unit No.7 
    As part of safety integrity verification of the reactor pressure vessel, pressure/leakage 
    test was conducted on June 3, 2008 by increasing the pressure to about 3.5 MPa-half of that 
    during normal operation.  The test showed no abnormality. Leak-rate test of the containment 
    vessel will be conducted from June 11 to confirm its leak-tightness.
