List of Findings and Violations
No findings or violations of more than minor significance were identified.
Additional Tracking Items
None.
PLANT STATUS
Unit 1 began the inspection period at rated thermal power and remained at or near rated thermal power for the remainder of the inspection period.
Unit 2 began the inspection period at rated thermal power. On September 16, 2024, Unit 2 commenced coastdown in preparation for the planned refueling outage 27 (S2R27) to start on October 6, 2024. Unit 2 was approximately 95 percent rated thermal power at the end of the inspection period.
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 performed activities described in IMC 2515, Appendix D, Plant Status, observed risk significant activities, and completed on-site portions of IPs. 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.

The inspectors reviewed the licensees implementation of its corrective action program related to the following issues:
- (1) Review of the evaluation and corrective actions associated with the preventive maintenance program for SSCs identified as obsolete, September 18, 2024
- (2) Review of the evaluation and corrective actions associated with fire watch compensatory measures and risk management action programs, July 25,
INSPECTION RESULTS
Observation: Failure to Control Transient Combustibles 71152A The inspectors reviewed the fire protection program specifically focused on fire watch implementation and execution for both fire compensatory measures and risk management actions. This included in-plant walkdowns of current fire watches, in-plant walkdowns of transient combustible permits (TCP), interviews with the fire protection engineer, interviews with fire protection superintendent, review of recent notifications that related to fire watches, and a review of the current fire program for fire watch implementation.
During a walkdown of two fire watch locations, it was identified that TCPs in the field were incorrectly created for fire areas that they were not located in. Specifically, two temporary cooling units were located inside the Units 1 and 2, 4kV switchgear rooms when their corresponding TCPs were written for them to be located inside the Units 1 and 2, 'C' battery rooms. This affects the combustible loading calculations performed for the battery rooms and the 4kV switchgear rooms and is not controlled in accordance with their Transient Combustible Control Procedure, FP-AA-011.
The inspectors identified a minor violation associated with combustible controls.
Minor Violation: The inspectors determined that the licensee's failure to implement and maintain in effect all provisions of the approved fire protection program as described in Section 9.5.1, "Fire Protection," of the Updated Final Safety Analysis Report, Salem Units 1 and 2, and required by Renewed Facility Operating Licenses (DPR-70 and DPR-75),
Conditions 2.C.5 and 2.C.10, "Fire Protection," was a violation. Specifically, the licensee failed to control two temporary cooling units by not tracking these transient combustibles to their appropriate fire area as required by FP-AA-011, "Control of Transient Combustible Material."
Screening: The inspectors determined this violation was minor because the fire areas where the transient combustibles were located had adequate combustible loading margin and therefore, had no impact on plant performance.
Enforcement:
PSEG initiated Notification (NOTF) 20971544 and corrected the TCPs to accurately reflect current plant configuration. This failure to comply with Salem Units 1 and 2, Renewed Operating Licenses (DPR-70 and DPR-75), Conditions 2.C.5 and 2.C.10, "Fire Protection," constitutes a minor violation that is not subject to enforcement action in accordance with the NRC's Enforcement Policy.
Observation: Review of the Preventive Maintenance Program for SSCs Identified as Obsolete 71152A The inspectors reviewed PSEGs corrective action program evaluation and corrective actions regarding adherence to preventive maintenance program for SSCs identified as obsolete.
Specifically, the inspectors focused on the chilled water systems and radiation monitors based on the main control room chiller upgrade project and notification entries for radiation monitors.
The issues and corrective actions completed were documented in PSEGs corrective action program as NOTFs 20955114, 02955656, 20941038, 20964295, 20970083, and 20954026.
PSEG completed work order 70233596 for a common cause evaluation for chiller issues. The overall common cause of the chiller issues trend was the initial design change package lacked quality and adherence to configuration change process procedures. Based on these findings, PSEG initiated actions to revise configuration change process procedures to include proper technical rigor and detail for design change packages from vendor technical documents, provide clarity for risk ranking, and additional screening requirements. PSEG documented radiation monitor notifications and performed corrective maintenance to resolve any challenges. PSEG continues to trend and address via the corrective action program any challenges in the radiation monitors.
The inspectors independently evaluated PSEGs corrective actions and preventive maintenance program associated with the chilled water systems and radiation monitors.
Additionally, the inspectors reviewed preventive maintenance changes to the frequencies and procedure steps. The inspectors did not identify any findings or violation of more than minor significance and, therefore, are not subject to enforcement action in accordance with the NRCs Enforcement Policy.
