SUMMARY
The U.S. Nuclear Regulatory Commission (NRC) continued monitoring the licensees performance by conducting a triennial fire protection inspection at Byron 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, 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 Disease (COVID-19), regional inspectors were directed to begin telework. During this time regional baseline inspections were evaluated to determine if all or portions of the objectives and requirements stated in the IP could be performed remotely. In some cases, portions of an IP were completed remotely and on-site. The inspection documented below was determined that the objectives and requirements stated in the IP could be completed remotely.
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) Division 11 Charging Pump
- (2) Upper Cable Spreading Room Fire Zone D1
- (3) Fire Suppression System Fire Pumps
Fire Protection Program Administrative Controls (IP Section 03.02) (1 Sample)
The inspectors verified that the following fire protection program administrative controls were implemented in accordance with the current licensing basis:
- (1) Combustible Control Program
Fire Protection Program Changes/Modifications (IP Section 03.03) (3 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 to verify that fire protection program documents and procedures affected by the changes were updated.
- (1) EC 402994 - GL 86-10 Evaluation for use of alternate compensatory measure associated with MCR fire/PORV block valves safe shutdown methodology
- (2) EC 381603 - GL 86-10 Evaluation of deviations from NFPA 13-1983 for foam sprinkler system in the unit 1 and unit 2 diesel oil storage tank rooms
- (3) EC 366688 - GL 86-10 Evaluation for revision of fireproofing drawings for clarification of requirements in 0A and 0B VC ventilation rooms
INSPECTION RESULTS
No findings were identified.
EXIT MEETINGS AND DEBRIEFS
The inspectors verified no proprietary information was retained or documented in this report.
- On January 29, 2021, the inspectors presented the triennial fire protection inspection results to Mr. K. McGuire, Operations Director and other members of the licensee staff.
