Audit Plan Operating Experience Review Audit Regarding the Surry Power Station, Unit Nos. 1 and 2 Subsequent License Renewal Application December 5 - 19, 2018 Division of Materials and License Renewal Office of Nuclear Reactor Regulation U.S. Nuclear Regulatory Commission Enclosure 1

1. Background By letter dated October 15, 2018 (Agencywide Documents Access and Management System (ADAMS) Package Accession No. ML18291A842), Virginia Electric and Power Company, LLC, (Dominion Energy Virginia or Dominion) submitted to the U.S. Nuclear Regulatory Commission (NRC or staff) an application to renew the Renewed Facility Operating License Nos. DPR-32 and DPR-37 for the Surry Power Station, Unit Nos. 1 and 2 (SPS) licenses for an additional 20 years beyond the current renewed 60-year current license terms, which expire on May 25, 2032, and January 29, 2033, for Unit 1 and Unit 2, respectively. The staff of the U.S. Nuclear Regulatory Commission (NRC) performs an independent review of plant-specific operating experience to identify examples of age-related degradation, as documented in the applicants corrective action program database.

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-2192, Rev. 0, Standard Review Plan for Review of Subsequent License Renewal Applications for Nuclear Power Plants (SRP-SLR), dated July 2017, and NUREG-2191, Rev. 0, Generic Aging Lessons Learned for Subsequent License Renewal (GALL-SLR) Report, dated July 2017.

3. Regulatory Audit Scope The scope of this subsequent license renewal regulatory audit of SPS is the NRC staffs independent review of plant-specific operating experience. The review is performed to identify pertinent examples of age related degradation, as documented in the applicants corrective action program database. The results of the audit will be used to support the NRC staffs further review of aging management programs (AMPs), time limited aging analyses (TLAAs) and aging management review (AMR) items to provide a basis for the NRC staffs conclusions on the ability of the applicants proposed AMRs, AMPs and TLAAs to manage the effects of aging in the subsequent period of extended operation.

The NRC staff will use risk insights to focus the breadth and depth of its review of plant-specific operating experience. However, the NRC staffs review is not limited to risk-significant systems and components because 10 CFR Part 54 is a deterministic rule. The NRC 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 10 CFR Part 54.

4. Information and Other Material Necessary for the Regulatory Audit As described in the Audit Needs List in Enclosure 2.

5. Team Assignments Area of Review Assigned Auditors (include, but not limited to)

Documentation of plant-specific operating Alan Huynh experience as described in the Surry Alexander Chereskin Power Station, Unit Nos. 1 and 2 Ali Rezai corrective action program (CAP) database. Andrew Johnson Disciplines include mechanical, materials, Andrew Prinaris structural, and electrical systems.

6. Logistics The audit will be conducted on location at the Excel Services Corporation offices in Rockville, Maryland, from December 5 - 19, 2018. Entrance and exit briefings will be held at the beginning and end of this audit, respectively.

7. Special Requests The NRC staff requests that Dominion staff at the audit perform special searches of the CAP database as requested by NRC staff. The NRC staff requests a suitable facility for the audit team to caucus during the audit and to hold meetings between NRC staff and Dominion personnel.

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

Operating Experience Audit Regarding the Surry Power Station Units 1 and 2, Subsequent License Renewal Application Audit Needs List

1. Corrective Action Program Database The U.S. Nuclear Regulatory Commission (NRC) staff requests that Virginia Electric and Power Company (Dominions) staff, using Dominion equipment, perform searches of the Dominions corrective action program (CAP) database as requested by NRC staff during the Operating Experience (OpE) Audit.

2. License Renewal Portal The staff requests electronic access, using their own equipment, to the Dominion license renewal portal.

3. Prepared Operating Experience Keyword Review Results The NRC staff requests that 10 years of plant-specific CAP entries be compiled into an excel workbook, organized by keywords. The data entered would be all CAP entries (e.g., issue reports, condition reports) that cite one of the keywords in the table below. This spreadsheet will be used by the staff during the OpE Audit. The parameters for the database should be as follows.

• The CAP entries should be compiled with an individual datasheet for each term. Some CAP entries could appear in multiple datasheets due to the use of multiple search terms when the CAP entry was initiated.

• At a minimum, each entry should include the CAP entry number, date of initiation, and the title of the CAP entry or a brief summary. The efficiency of the staffs screening review is increased with more details in the excel spreadsheet. For example, a simple title might result in the CAP entry appearing to be an applicable age-related issue; however, when the full entry is reviewed, it may be noted that the degradation was not age related (e.g., damage during excavating buried pipe, damage to internal coatings as a result of scaffold installation).

• Though not required, including plant system numbers in the CAP entries, can improve the efficiency of the staffs review. Specifically, generic search terms such as corros, indication, pit, etc., provide a large number of entries and the staffs search time can be significantly reduced if the plant system is identified.

The staff requests electronic access, using Dominion equipment, to the results of the operating keyword list query of Dominions corrective action database. The results are expected to be in an excel workbook, organized by keywords.

Enclosure 2

OE Key Word Search Terms for Surry OpE Audit It would be helpful to the staff to have one datasheet which incorporates all of the entries associated with the OpE key word terms. This datasheet would be used by staff to search for CAP entries that might not be associated with a specific OpE search term, but is of interest due to data reviewed by accessing the search terms.

For terms enclosed in quotation marks, the intent is that when compiling the database, only CAP entries where the term is used independently are included. For example, for age, CAP entries would not be included where age was used in package or signage.
