SUMMARY
The U.S. Nuclear Regulatory Commission (NRC) continued monitoring the licensees performance by conducting a triennial fire protection inspection at Nine Mile Point Nuclear Station, 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 a 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.
However, all the inspection activities were performed onsite.
REACTOR SAFETY
===71111.21N.05 - Fire Protection Team Inspection (FPTI)
Structures, Systems, and Components (SSCs) Credited for Fire Prevention, Detection, Suppression, or Post-Fire Safe Shutdown Review (IP Section 03.01)===
The inspectors verified that the following systems credited in the approved fire protection program could perform their licensing basis function:
- (1) Unit 1 Emergency Cooling System
- (2) Unit 1 Core Spray System
- (3) Unit 1 Fire Protection Water Supply System
- (4) Unit 1 Fire Barriers
- (5) Unit 2 Safety Relief Valves
- (6) Unit 2 Residual Heat Removal System
- (7) Unit 2 Fire Protection Water Supply System
- (8) Unit 2 Fire Barriers
Fire Protection Program Administrative Controls (IP Section 03.02) (4 Samples)
The inspectors verified that the selected administrative control or process was implemented in accordance with the current licensing basis. The inspectors ensured that the fire protection program contained adequate procedures to implement the selected administrative control and that the selected administrative control met the requirements of all committed industry standards.
- (1) Unit 1 Fire Protection System Impairment Control
- (2) Unit 1 National Fire Protection Association (NFPA) 805 Monitoring Program
- (3) Unit 2 Fire Protection System Impairment Control
- (4) Unit 2 Combustible Control Program
Fire Protection Program Changes/Modifications (IP Section 03.03) (4 Samples)
The inspectors reviewed the following changes to ensure that they did not constitute an adverse effect on the ability to safely shutdown post-fire and did not degrade assumptions and performance capability stated in the safe shutdown analysis. The inspectors verified that fire protection program documents and procedures affected by the changes were updated.
- (1) Unit 1 ECP-20-000210, Upgrade Diesel Fire Pump Alternate Supply Fuse
- (2) Unit 1 ECP-21-000074, Extend Surveillance Testing Interval of the Electric Fire Pump
- (3) Unit 2 FPEE2-19-001, Use of Non-IEEE-383 Rated Cabling on the Refueling Floor
- (4) Unit 2 FPEE2-20-001, Review of Fire Damper Testing
INSPECTION RESULTS
No findings were identified.
EXIT MEETINGS AND DEBRIEFS
The inspectors verified no proprietary information was retained or documented in this report.
- On August 12, 2021, the inspectors presented the triennial fire protection inspection results to Mr. Adam Schuerman and other members of the licensee staff.
