Report for the Operating Experience Review Audit Surry Power Station, Unit Nos. 1 and 2 Subsequent License Renewal Application
- 1. Introduction The U.S. Nuclear Regulatory Commission (NRC or the staff) conducted an audit of Virginia Electric and Power Companys (Dominion Energy Virginia or Dominion) Surry Power Station, Unit Nos. 1 and 2 (SPS or the applicants), plant-specific operating experience (OpE), as part of the staffs review of the SPS subsequent license renewal application (SLRA) at the EXCEL Services Corporation located in Rockville, Maryland, from December 6 to 19, 2018. The purpose of the audit was for the NRC staff to perform an independent review of plant specific OpE to identify examples of age-related degradation, as documented in the applicants corrective action program database. The regulatory bases for the audit was Title 10 of the Code of Federal Regulations, Part 54, Requirements for Renewal of Operating Licenses for Nuclear Power Plants, (10 CFR Part 54). The staff also considered the guidance contained 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.
The identified OpE examples will be further evaluated during the staffs subsequent technical review and auditing of aging management programs (AMPs), time limited aging analyses (TLAAs) and aging management review (AMR) line items. The staffs identification and evaluation of pertinent OpE and additional related documentation, provides a basis for the staffs conclusions on the ability of the applicants proposed AMPs and TLAAs to manage the effects of aging in the period of extended operation.
- 2. Audit Activities The following sections discuss the areas reviewed by the staff and identified examples of pertinent OpE.
SLRA AMP B2.1.1, ASME Section XI Inservice Inspection, Subsections IWB, IWC, and IWD Audit Activities. The staff conducted an independent search of Dominions operating experience database using keywords: : cracking, crack, leak, leakage, flaw, failure, degradation, and weld.
The table below lists the documents that were reviewed by the staff and were found relevant to the ASME Section XI Inservice Inspection, Subsections IWB, IWC, and IWD program.

Date CR1084941 Engineering was asked to inspect a passive fire 11/29/2017 barrier along the south wall, which showed a whole completely through a box.
CR1085782 A fire barrier that protects discharge piping was 12/12/2017 identified as breached (CR1084941). Pictures reveal corrosion at the location of the fire barrier failure. A work order was created to remove portions of the barrier and inspect the piping and supports with appropriate contingency plans.

Date CR565907 A fire barrier penetration did not have the required 11/20/2014 semkit foam seal installed. The penetration does not have an actual location number.
CR544364 Penetration between the Unit 2 normal switchgear 04/09/2014 room and the Unit 2 turbine building contains a one-inch steel conduit grouted into the block wall with a pull box on each side of the wall. An inspection showed that no foam was installed in the conduit through the wall. In this condition, the penetration would not have performed tis function as a 3-hour rated fire barrier. Once new cables are pulled in, foam will be installed in the conduit as part of the modification package.
CR540746 Appendix R penetration is not sealed. Cables 02/25/2014 currently installed are spares and are scheduled to be removed to permit installation of new cabling, which will then be sealed.
CR540963 Corrective Action 278440 was assigned to 02/27/2014 engineering to determine and initiate required actions and to perform and extent of condition walkdown based on penetration documented in CR540746.
One similar penetration in Unit 2 was identified without sealant inside the conduit, but no other penetrations of this type were noted in either unit.
CR491395 The fire barrier penetration between the Unit 1 Cable 10/12/2012 Tunnel and Cable Vault, in the cable trays are is not in compliance with the station fire barrier requirements. The requirement is to have 10 inches of fire material in the penetration to achieve a 3-hour fire barrier. The wall is 6 inches thick and the material in the wall penetration is also 6 inches. An additional 4 inches of material is required by procedure.
CR024815 The foamed piping penetration in the wall between 11/13/2017 the MSVH and CSPH is not shown in the Technical Requirements Manual (TRM) as a fire barrier. A door that penetrates the same wall is shown as a balance of plant fire door. It is unclear if the piping penetration is a fire barrier. Recommended corrective action is to determine the correct classification of the door, wall, and foamed penetration, and initiate any changes.

CR1074953 Fire Protection/Appendix R Health Report overall 08/03/2017 rating is white for the second quarter of 2017 with several Yellow and Red Health attributes. The Red attribute is that an Appendix R fire door has excessive gap under the active door leaf, and is non-functional.

To date approximately 50 QDR packages still require updating as a result of the License Renewal Project. A tracking mechanism was not identified to be in place to ensure the timely completion of the remaining QDRs. This is not an operability issue because neither Surry or North Anna have exceeded the 40 year life cycle and EQ equipment affect by the unrevised QDRs is currently qualified and managed to a 40 year life cycle.

These do not affect the switches ability to perform their design function. However, after June 8, 2010, they will not be EQ qualified without evaluation. The qualified life for the switches has been evaluated and it has been determined that it can be extended until the next 2010 Unit 1 outage.
