  Electric Power Company, Incorporated (TEPCO) provides this announcement containing 
  incidents information reported from July 24th to July 30th, 2008. 

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


 < Reports from July 24 to July 30, 2008 >


 ○ Other Findings 
   • Unit No.6 and Unit No.7 
     Inspections for forks of rotor blades on the 14th, 15th and 16th stage of low-pressure 
     turbine (A) (B) and (C) were completed on July 28th, 2008. The results are as follows. 


   • Unit No.6
     As part of safety integrity verification of the reactor pressure vessel, pressure/leakage 
     test was conducted on July 17, 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 was conducted from July 25th to July 26th, 2008 to confirm its 
     leak-tightness. As a result, no abnormality was found.
