Scoping and Screening Methodology Audit for the River Bend Station, Unit 1, License Renewal Application

1. Background The NRC staff will perform a review of the methodology used by the applicant to identify the systems, structures and components (SSCs) to be included within the scope of license renewal and subject to an aging management review (AMR) in accordance with the requirements of Title 10 of the Code of Federal Regulations (10 CFR) Parts 54.4(a) and 10 CFR 54.21. These activities are performed as part of the staffs review of the River Bend Station, Unit 1 (River Bend), license renewal application.

2. Regulatory Audit Bases License renewal requirements are specified in 10 CFR Part 54, Requirements for Renewal of Operating Licenses for Nuclear Power Plants. Guidance is provided in NUREG-1800, Rev. 2, Standard Review Plan for Review of License Renewal Applications for Nuclear Power Plants (SRP-LR), dated December 2010, and NUREG-1801, Rev. 2, Generic Aging Lessons Learned (GALL) Report, dated December 2010.

3. Regulatory Audit Scope The scope of this regulatory audit is to review the applicants scoping and screening methodology used to identify SSCs within the scope license renewal and subject to aging management review. The review is performed to evaluate the scoping and screening process as documented in the license renewal application, implementing procedures, reports and drawings, such that the staff:

• Obtains an understanding of the process used to identify the SSCs within the scope of license renewal and to identify the structures and components subject to an aging management review.

• Has sufficient docketed information to allow the staff to reach a conclusion on the adequacy of the scoping and screening methodology as documented and applied.

4. Information and Other Material Necessary for the Regulatory Audit As described in the Audit Needs List.

5. Team Assignments and Schedule Team members are Angela Buford, David Nold and Bill Rogers and are assigned the following activities as indicated in the schedule.
