REQUEST FOR ADDITIONAL INFORMATION STP NUCLEAR OPERATING COMPANY LICENSE RENEWAL APPLICATION DISCUSSED ON CONFERENCE CALL OCTOBER 6, 2011 Draft RAI 3.3.2.19-1 Flow-Accelerated Corrosion (018)
Background:
The standard review plan for review of license renewal (SRP-LR) states that the "Evaluation Findings" subsections present conclusions which include a determination as to whether the applicant has adequately identified the aging effects and the aging management program (AMP) credited with managing the aging effects. The Generic Aging Lessons Learned (GALL) Report states the conditions and operating experience at the plant must be bound by the conditions and operating experience for which the GALL Report program was evaluated. Otherwise, it is incumbent on the applicant to augment the GALL program as appropriate to address the additional aging effects.
The Flow-Accelerated Corrosion (FAC) Program is credited for managing aging due to wall thinning of various carbon steel components in license renewal application (LRA)
Tables 3.3.2-19, "Chemical and Volume Control," Table 3.3.2-22, "Liquid Waste Processing,"
and Table 3.4.2-2, "Auxiliary Steam System and Boilers," as well as several other tables.
Issue:
The implementing procedure for the FAC Program and the FAC Program Manual provides lists of systems that are susceptible to FAC; however, the lists in these documents do not include the three systems cited above. It is not clear whether the current FAC program, as implemented at the site, includes the components cited in the LRA.
In addition, the implementing procedure for the FAC Program, states that an erosion/corrosion program has been developed, which includes wall thinning of piping systems that are not included in the FAC Program, and addresses damage caused by cavitation, flashing and impingement. It is not clear whether there are components within the scope of license renewal, that are being managed for wall thinning by an erosion/corrosion program, which are not included in the FAC Program.
Request:
- 1) Provide information demonstrating that the current flow-accelerated corrosion program includes the associated components specified in LRA Tables 3.3.2-19, 3.3.2-22, and 3.4.2-2, or clarify which aging management program addresses wall thinning for these components.
ENCLOSURE 2
- 2
- 2)
If there are components within the scope of license renewal that are being managed for wall thinning by a separate erosion/corrosion program, provide details about this plant-specific program and clarify which components listed in the LRA are managed by this program.
Discussion:
The staff and the applicant discussed this Request for Additional Information. The applicant clarified its FAC Program and how it incorporates and manages its component within the FAC Program. The applicant understands the staff's concerns and will submit a response. The staff will issue the RAI.
