 <Reports from Apr. 10 to Apr. 16, 2008>




 ○  Other Findings 
  • Unit No.7: 
    Partial breakages were found on forks of 2 rotor blades on the turbine-side of 
    14th-stage of the low-pressure turbine (B) and (C). Investigation of the causes 
    and detailed inspection are going on. Non-destructive inspection was conducted 
    for fixtures of rotor fork of the 14th-stage of the low-pressure turbine (A), (B) 
    and (C) (announced on March 13th,  March 19th, March 27th, April 3rd and April 10th,
    2008).
    As a result, indication was not found.
    Investigation on the cause of the damages and the indication will be continued 
    as well as the visual inspection and non-destructive inspection for forks of rotor 
    blades on the 15th and 16th stages of the low-pressure turbine (B) which have the 
    same structure as forks of rotor blades on 14th stage.
