Aging Management Programs RAI82.1.16-2 In its July 7, 2010, response to request for additional information (RAI) 82.1.16-2, the applicant described the details of the One-Time Inspection Program inspection techniques. However, the staff was not clear if the scope of the program has been defined to include eddy current testing of heat exchanger tubes in an environment comparable to the non-regenerative heat exchangers.
Discussion:
Pacific Gas & Electric Company agreed to supplement the response to RAI 82.1.16-2.
RAI 82.1.19-2 In its July 7, 2010, response to RAI B2.1.19-2, the applicant provided justification for the use of the ASME Code Class 1 Small-Bore Piping Program. However, the staff was unclear of the full history of failures in Class 1 small-bore piping. The staff was also unclear about the sampling size and methodology of the program.
Discussion:
The staff will issue a follow-up RAI to clarify the relevant plant-specific operating experience and the program's sampling size and methodology.
