CR-IPJ-2006-02270 Name Review both Unit 2 and Unit 3 F AC Programs and determine if similar locations to this leak have been inspected for wall thinning. Also determine if and when additional inspections are required to determine if wall thinning is occuring at these similar locations. If additional inspections are required, incorporate inspections into work week schedule, or F AC Program outage scopes.
Response
A review of both Unit 2 and Unit 3 F AC programs was performed to determine if similar locations to the current Reheater Drain line leak have been inspected for wall thinning and determine if and when additional inspections are required to determine if wall thinning is occurring at these similar locations.
Review of the Unit 2 F AC inspection history found that all similar locations have been recently inspected or replaced. No additional inspections are recommended for Unit 2 at this time.
Review of the Unit 3 F AC inspection history found that some similar locations do not have recent inspections and should be inspected. A total of9 additional inspections were identified.
Details of this review, along with the recommended additional inspections are attached.
No on-line exams are recommended due to the high temperature (385 degrees F) of these components, and the congestion of piping in these areas. Therefore the 9 additional inspections are to be performed during the 3RI4 refuel outage.
CA 3 is issued to generate work orders and 3R 14 scope add forms fo~ these inspections.
