Onsite Aging Management Program Regulatory Audit for the River Bend Station, Unit 1, License Renewal Application

1. Background By letter dated May 25, 2017, Entergy Operations, Inc. (Entergy), submitted to the U.S. Nuclear Regulatory Commission (NRC or the staff) its application for renewal of Operating License No.

NPF-47 for the River Bend Station, Unit 1 (RBS). The staff from the Division of Materials and License Renewal will lead an onsite regulatory audit to gain a better understanding of Entergys aging management programs (AMPs), aging management review (AMR) items, Time-Limited Aging Analyses (TLAA), and associated bases and documentation as applicable.

2. Regulatory Audit Bases License renewal requirements are specified in Title 10 of the Code of Federal Regulations (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 onsite regulatory audit is to verify, for selected systems, structures and components (SSCs), that the conditions at the plant are bounded by the conditions for which the GALL Report program was evaluated. This will be accomplished by performing plant walk downs to observe material conditions and SSC configurations. The staff will also examine Entergys program bases documents and related references, as required to support observations made during plant walkdowns, for AMPs, AMR items, and TLAAs, and interview Entergy representatives to obtain additional clarification.

The staff will use risk insights to inform the prioritization of its review activities associated with AMPs, AMR items, and TLAAs. The staff will use risk insights to focus on the breadth and depth of its review when selecting SSCs to be subject to walkdowns for observation of material conditions and SSC configurations. However, the staffs review is not limited to risk significant systems and components because 10 CFR Part 54 is a deterministic rule and the staff must conclude that there is reasonable assurance that activities will continue to be conducted in accordance with the current licensing basis and the effects of aging will be managed during the period of extended operation for all structures and components within the scope of Part 54. The staff has reviewed the list of risk significant systems and components (from PRA, Revision 5) provided in a presentation to the staff on May 25, 2017. The staff augmented this list with the fire protection and fire water systems because they are typically risk significant when considering external events.

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

5. Team Assignments Areas of Review Assigned Auditors Staff identified SSCs for which the direct observations of Allik, Brian - Materials material conditions or plant configurations will contribute Gavula, Jim - Mechanical to the information required for the staff to make a safety Ngola, Otto - Electrical conclusion. Nguyen, Duc - Electrical Sadollah, Mohammad - Electrical These areas may include: Sayoc, Emmanuel - Project Management Auxiliary systems (service water, buried piping, standby service water, and fuel oil systems)

Electrical systems (Station blackout related systems, Environmental Qualification electrical cables, and components)

6. Logistics The audit will be conducted onsite at River Bend Station, Unit 1, on November 6-9, 2017.

Entrance and exit briefings will be held at the beginning and end of this audit, respectively.

7. Special Requests The staff requests Entergy to provide electronic access to applicant information, as discussed in the Audit Needs List. The NRC staff requests a suitable facility for the audit team to caucus during the audit and to hold meetings between staff and Entergy personnel.

8. Deliverables An audit report should be issued to the Entergy within 90 days from the end of the audit.
