INSPECTION SCOPES

Inspections were conducted using the appropriate portions of the inspection procedures (IPs) in effect at the beginning of the inspection unless otherwise noted. Currently approved IPs with their attached revision histories are located on the public website at http://www.nrc.gov/reading- rm/doc-collections/insp-manual/inspection-procedure/index.html. Samples were declared complete when the IP requirements most appropriate to the inspection activity were met consistent with Inspection Manual Chapter (IMC) 2515, “Light-Water Reactor Inspection Program - Operations Phase.” The inspectors reviewed selected procedures and records, observed activities, and interviewed personnel to assess licensee performance and compliance with Commission rules and regulations, license conditions, site procedures, and standards.

OTHER ACTIVITIES – TEMPORARY INSTRUCTIONS, INFREQUENT AND ABNORMAL

71003 - Post-Approval Site Inspection for License Renewal

From June 1, 2020 to June 19, 2020, the NRC continued monitoring Duke Energy's performance at McGuire by conducting a Post-Approval Site Inspection for License Renewal - Phase II in accordance with the license renewal inspection program (LRIP). This inspection took place prior to the period of extended operation (PEO) for Units 1 and 2, which will begin on June 13, 2021 and March 4, 2023, respectively. Per Inspection Manual Chapter 2516, the LRIP is the process used by NRC staff to verify the adequacy of aging management programs (AMPs), Time Limited Aging Analyses (TLAAs), and other activities associated with an applicant’s request to renew an operating license of a commercial beyond the initial licensing period under 10 CFR Part 54, “Requirements for the Renewal of Operating Licenses for Nuclear Power Plants.”

Post-Approval Site Inspection for License Renewal (4 Samples)

(1) License Conditions and Commitments for License Renewal, Implementation of Aging Management Programs and Time-Limited Aging Analyses

There are a total of 62 license renewal action items linked to the renewed operating license for McGuire Nuclear Plant Units 1 and 2, issued in December 2003, which include the following: 2 conditions required directly by the renewed operating license; 21 commitments to enhance existing AMPs; 34 commitments to implement AMPs; and 5 TLAAs. The inspectors reviewed a majority (greater than 70%) of regulatory commitments and associated AMPs and TLAAs in order to assess the adequacy and effectiveness of the license renewal program. For each item selected in the sample, the inspectors also reviewed the applicable license renewal program documents and conducted interviews with licensee staff to verify that the licensee completed the actions necessary to comply with the conditions listed in the renewed facility operating license. For those license renewal action items that were not completed at the time of this inspection, the inspectors verified, where possible, that there was reasonable assurance that such action items were on track for completion prior to the PEO or in accordance with an established implementation schedule consistent with the license renewal application (LRA), the NRC safety evaluation report (SER), and the Updated Final Safety Analysis Report (UFSAR) supplement.

The items selected for the inspection sample are listed below along with the completion status of the item at the time of the inspection. The full description of

3

each item is available in the UFSAR supplement for license renewal, as revised, the Integrated Technical Specifications (ITS), and Appendix A of the NRC SER issued in 5 parts as NUREG-1772 (ML030830181, ML030850152, ML030850164, ML030380218, ML030850237).

Conditions: • Condition 1: Analysis of Pressure-Temperature Limit Curves at 34 Effective Full-Power Years for McGuire Unit 1 Reactor Vessel (License Amendment #269). Status: Complete.

• Condition 2: Analysis of Pressure-Temperature Limit Curves at 34 Effective Full-Power Years for McGuire Unit 2 Reactor Vessel (License Amendment #249). Status: Complete.

In addition, preventative maintenance task orders to track the performance of the BMI thimble tube inspections and associated follow up actions for both units during the PEO have not been developed yet. Based on the review of the administrative controls in place to track the pending actions, the inspectors determined that there was reasonable assurance that the licensee would complete the necessary actions in accordance with the AMP.

(2) Newly Identified Structures, Systems, and Components (SSCs)

Since the renewed license was issued, the licensee has performed an assessment to identify any structures, systems and components (SSCs) that would have been subject to an aging management review or evaluation as a time-limited aging analysis

7

in accordance with 10 CFR 54.21. The inspectors reviewed the licensee’s assessment and noted that the following SSCs were identified as being within the scope of license renewal and subject to aging management review:

• Nuclear Service Water Strainer Elements

• Liquid Waste System - Control Room Air Handling Drains

• Boral Spent Fuel Rack Neutron Attenuation Material

• Earthen Dike on the North Perimeter of the McGuire Nuclear Station Site

• Auxiliary Feedwater Storage Tanks

For each newly identified SSC, the inspectors determined that the licensee took appropriate actions in accordance with 10 CFR 54.37(b). Specifically, the inspectors verified that the SSCs have been included in the FSAR update required by 10 CFR 50.71(e), and that the FSAR update described how the effects of aging are managed such that the intended function(s) in 10 CFR 54.4(b) will be effectively maintained during the period of extended operation. The inspectors also reviewed a list of plant modifications performed from the time the LRA was submitted to the time the renewed operating license was issued, to identify any potentially new SSCs that would have been subject to aging management review at the time the NRC was reviewing the LRA. Based on this review, the inspectors did not identify any new SSCs that were subject to the provisions of 10 CFR 54.37(b).

(3) Description of Aging Management Programs in the UFSAR Supplement

As part of the review of implementation activities for the selected AMPs, the inspectors reviewed the corresponding UFSAR sections to verify that the program descriptions were consistent with the license renewal application and the corresponding section of the NRC safety evaluation report. The inspectors reviewed three versions of the UFSAR supplement for license renewal as follows:

• The inspectors reviewed the UFSAR supplement submitted with the LRA, as revised, to identify the program attributes and future inspection activities that were originally relied upon for the approval of the renewed operating license.

• The inspectors reviewed the revision of the UFSAR submitted to the NRC pursuant to the requirements in 10 CFR 50.71(e)(4) following the issuance of the renewed operating license to verify that the UFSAR supplement for license renewal was included as required by the condition of the renewed operating license.

• The inspectors reviewed the latest revision of the UFSAR supplement for license renewal (Revision 21) to verify that the program attributes and inspection activities were consistent with the AMPs as originally approved by the NRC and subsequent revisions performed under the provisions of 10 CFR 50.59. The inspectors also verified that any changes caused by the inclusion of newly identified SSCs were included in the UFSAR supplement.

8

(4) Changes to license renewal commitments and the UFSAR supplement for license renewal

As part of the review of license renewal conditions, commitments, AMPs, and TLAAs described in this report, the inspectors reviewed a sample of license renewal commitment change documents to verify the licensee followed the guidance in NEI 99-04, “Guidelines for Managing NRC Commitment Changes,” for any change to the commitments, including their elimination. Except as identified in the Inspection Results section of the report, the inspectors verified that the licensee properly evaluated, reported, and approved where necessary, changes to license renewal commitments listed in the UFSAR in accordance with 10 CFR 50.59, as required by the Renewed Operating License (Section 2.C.(31))

INSPECTION RESULTS

No findings were identified.

EXIT MEETINGS AND DEBRIEFS

The inspectors verified no proprietary information was retained or documented in this report.

• On June 18, 2020, the inspectors presented the NRC inspection results to Mr. Tom Ray, Site Vice President, and other members of the licensee staff.
