SUBJECT:

MCGUIRE NUCLEAR STATION, UNITS 1 & 2 - DESIGN BASIS ASSURANCE INSPECTION (PROGRAMS) INSPECTION REPORT 05000369/2020010 AND 05000370/2020010

Dear Mr. Ray:

On September 14, 2020, the U.S. Nuclear Regulatory Commission (NRC) completed an inspection at McGuire Nuclear Station, Units 1 & 2. On October 5, 2020, the NRC inspectors discussed the results of this inspection with you and other members of your staff. The results of this inspection are documented in the enclosed report.

No findings or violations of more than minor significance were identified during this inspection.

This letter, its enclosure, and your response (if any) will be made available for public inspection and copying at http://www.nrc.gov/reading-rm/adams.html and at the NRC Public Document Room in accordance with Title 10 of the Code of Federal Regulations 2.390, Public Inspections, Exemptions, Requests for Withholding.

Sincerely,

/RA/

James B. Baptist, Chief Engineering Branch 1 Division of Reactor Safety Docket Nos. 05000369 and 05000370 License Nos. NPF-17 and NPF-9

Inspection Report

Docket Numbers: 05000369 and 05000370 License Numbers: NPF-9 and NPF-17 Report Numbers: 05000369/2020010 and 05000370/2020010 Enterprise Identifier: I-2020-010-0041 Licensee: Duke Energy Carolinas, LLC Facility: McGuire Nuclear Station, Units 1 & 2 Location: Huntersville, NC Inspection Dates: June 22, 2020 to September 14, 2020 Inspectors: P. Braxton, Reactor Inspector N. Morgan, Reactor Inspector G. Ottenberg, Senior Reactor Inspector Approved By: James B. Baptist, Chief Engineering Branch 1 Division of Reactor Safety Enclosure

SUMMARY

The U.S. Nuclear Regulatory Commission (NRC) continued monitoring the licensees performance by conducting a design basis assurance inspection (programs) inspection at McGuire Nuclear Station, Units 1 & 2, in accordance with the Reactor Oversight Process. The Reactor Oversight Process is the NRCs program for overseeing the safe operation of commercial nuclear power reactors. Refer to https://www.nrc.gov/reactors/operating/oversight.html for more information.

List of Findings and Violations

No findings or violations of more than minor significance were identified.

Additional Tracking Items

None.

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.

Starting on March 20, 2020, in response to the National Emergency declared by the President of the United States on the public health risks of the coronavirus (COVID-19), inspectors were directed to begin telework. In addition, regional baseline inspections were evaluated to determine if all or portion of the objectives and requirements stated in the IP could be performed remotely. If the inspections could be performed remotely, they were conducted per the applicable IP. In some cases, portions of an IP were completed remotely and on site. The inspections documented below met the objectives and requirements for completion of the IP.

REACTOR SAFETY

71111.21N.02 - Design-Basis Capability of Power-Operated Valves Under 10 CFR 50.55a Requirements POV Review (IP Section 03)

The inspectors:

a. Evaluated whether the sampled POVs are being tested and maintained in accordance with NRC regulations along with the licensees commitments and/or licensing bases.

b. Evaluated whether the sampled POVs are capable of performing their design-basis functions.

c. Evaluated whether testing of the sampled POVs is adequate to demonstrate the capability of the POVs to perform their safety functions under design-basis conditions.

d. Evaluated maintenance activities including a walkdown of the sampled POVs (if accessible).

(1) 1NI-10B, Unit 1 NV Pumps to NC Cold Legs

(2) 2KC-56A, 2A ND Heat Exchanger KC Inlet Isolation

(3) 2NI-184B, 2B ND Pump Suction from Containment Sump

(4) 1SA-49AB, 1B Steam Generator SM Supply to Unit 1 Turbine Driven CA

(5) 1CA-54AC, Unit 1 Turbine Driven CA Pump Discharge to 1B Steam Generator

(6) 1SASV-0490, 0491, 0492, SOVs associated with 1SA-49AB, 1B Steam Generator SM Supply to Unit 1 Turbine Driven CA

(7) 2NC-31B, Unit 2 Pressurizer Power Operated Relief Valve Block Valve

(8) 2NC-32B, Unit 2 Pressurizer Power Operated Relief Valve

(9) 1NS-1B, Unit 1 Containment Sump Block Valve

INSPECTION RESULTS

No findings were identified.

EXIT MEETINGS AND DEBRIEFS

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

• On October 5, 2020, the inspectors presented the design basis assurance inspection (programs) inspection results to Mr. Tom Ray, Site Vice President and other members of the licensee staff.

• On July 9, 2020, the inspectors presented the pre-walkdown completion inspection results to Mr. Tom Ray, Site Vice President and other members of the licensee staff.
