SUBJECT:
MCGUIRE NUCLEAR STATION, UNITS 1 AND 2 - NRC TRIENNIAL FIRE PROTECTION INSPECTION REPORT NOS. 05000369/2018011 AND 05000370/2018011
Dear Mr. Ray,
On May 17, 2018, the U. S. Nuclear Regulatory Commission (NRC) completed an inspection at your McGuire Nuclear Station, Units 1 and 2 and 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.
The NRC inspectors did not identify any finding or violation of more than minor significance.
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 10 CFR 2.390, Public Inspections, Exemptions, Requests for Withholding.
Sincerely,
/RA/

SUMMARY
The U.S. NRC continued monitoring licensees performance by conducting a triennial fire protection inspection (TFPI) at McGuire Nuclear Station, Units 1 and 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 were identified.
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/inspectionprocedure/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.
REACTOR SAFETY
===71111.05XT - Fire Protection - NFPA 805 (Triennial)
The inspectors evaluated the following from April 30, 2017 - May 17, 2017:
Fire Protection Inspection Requirements ===
The inspectors evaluated fire protection program implementation in the following selected areas:
- (1) FA 2, Unit 1 Motor Driven CA Pump Room
- (2) FA 2A , Unit 1 Turbine Driven CA Pump Room
- (3) FA 9-11, Unit 1 B Train Electrical Pen Room & Switchgear Room
- (4) FA 14, Aux Building Common-Elevation 733
B.5.b Inspection Activities (1 Sample)
The inspectors evaluated feasibility of the following B.5.b Mitigating Strategies:
- (1) Spent Fuel Pool External Makeup
INSPECTION RESULTS
Unresolved Item Question about treatment of well-sealed, robustly secured 71111.05XT (Open) cabinets in the Fire PRA
Description:
Inspectors identified an unresolved item (URI) associated with how the site calculated fire frequencies of electrical cabinets in the fire PRA. The site retained floor-mounted electrical cabinets characterized as well-sealed and robustly-secured as ignition sources in the fire PRA. The guidance of NUREG-6850, which the site is committed to, instructs that electrical cabinets housing voltages less than 400V, and that are characterized as well-sealed and robustly secured not be counted as ignition sources. This is because the fire PRA should only consider fires that can propagate to other combustibles and targets, and by including ignition sources that cannot propagate to other combustibles and targets, the frequency of fires in other electrical cabinets that can actually propagate could be erroneously lowered.
Inspectors noted that retaining floor-mounted cabinets characterized as well-sealed and robustly-secured appeared to not be in alignment with the sites NFPA 805 submittal, and associated SE, which each contain information specific to the question about how well-sealed robustly secured cabinets were treated in the fire PRA. The SE states, Regarding the counting of well-sealed, robustly-secured electrical cabinets having circuits less than 440V, the licensee stated in its response to PRA RAI 03.b.01 that it updated the FPRA to remove cabinets meeting this definition. The site has asserted that this statement in the SE is incorrect, and does not align with what the site submitted on the docket as a part of their NFPA 805 submittal.
Planned Closure Action(s): This issue is being characterized as a URI, pending a decision from NRR as to the interpretation of the sites submittal regarding treatment of floor-mounted well-sealed and robustly-secured cabinets, and the accuracy of the associated SER.
NRC Tracking Number: 05000369,370/2018-011-01
EXIT MEETINGS AND DEBRIEFS
The inspectors verified no proprietary information was retained or documented in this report.
The inspectors confirmed that proprietary information was controlled to protect from public disclosure.
On May 17, 2018, the lead inspector presented the preliminary inspection results to Mr. T. Ray and other members of the licensees staff.
