SUMMARY
The U.S. Nuclear Regulatory Commission (NRC) continued monitoring the licensees performance by conducting an integrated inspection at Hope Creek Generating 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.
PLANT STATUS
The Hope Creek Generating Station (Hope Creek) began the inspection period offline during scheduled refueling outage H1R24. Hope Creek started up on October 28, 2022 and reached rated thermal power (RTP) on November 5, 2022. Subsequently, on November 5, 2022, reactor power was lowered to approximately 70 percent RTP for a rod pattern adjustment (RPA) and returned to RTP on November 6, 2022. On November 11, 2022, reactor power was lowered to 70 percent RTP to support an RPA. Hope Creek maintained 85 percent RTP following the RPA to perform maintenance on the 'C' reactor feed pump. Following the maintenance, on November 16, 2022, Hope Creek returned to RTP and remained at or near RTP for the remainder 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) 'C' station service water pump vibration levels in the alert range during the week of November 21, 2022
71152S - Semiannual Trend Problem Identification and Resolution Semiannual Trend Review (Section 03.02)
- (1) The inspectors reviewed PSEG's corrective action program for trends that might be indicative of a more significant safety issue.
INSPECTION RESULTS
Observation: Annual Follow-up - 'C' Station Service Water (SSW) System 71152A Elevated Vibrations The inspectors evaluated PSEG's corrective actions associated with elevated vibration levels on the safety-related 'C' SSW pump. The condition and corrective actions completed were documented in PSEG's corrective action program (CAP) under notifications (NOTFs)20898722, 20905320, 20910533, 20910855, 20910856, 20911114, 20915740, and 20918430. PSEG performed an operability evaluation (70224461) and determined the 'C' SSW pump was able to fulfill its specified safety functions with the degraded condition. PSEG also completed an equipment reliability evaluation 70224588, which determined that internal pump degradation was the direct cause of the elevated vibration levels. Subsequently, PSEG replaced the pump shaft sleeve and coupling under work order 60155398, and pump vibration levels were restored to an acceptable range.
Additionally, the inspectors performed a walkdown of the SSW system to assess material conditions and to determine whether PSEG was appropriately identifying conditions adverse to quality, documenting them in the CAP, and correcting them commensurate with their safety significance. On November 8, 2022, the inspectors identified additional concrete spalling on the 'C' SSW pump concrete pedestal, which was previously related to a Green non-cited violation documented in inspection report 05000354/2022002 (ADAMS Accession No.
ML22221A177). PSEG documented inspectors' concerns in NOTF 20920533, performed equipment walkdowns, and determined the additional spalled concrete was bounded by the technical evaluation performed under 70222204 and did not impact the operability of the pump. Additionally, on November 8, 2022, the inspectors identified surface corrosion and flaking on the 'D' SSW pump strainer discharge flange piping, which PSEG had not previously identified or evaluated in the CAP. PSEG entered this issue in NOTF 20922228 and promptly evaluated it. PSEG performed an ultrasonic thickness examination of the area and identified that the area of concern was well above the minimum wall thickness requirements. Therefore, the condition did not impact the 'D' SSW pump's ability to perform its safety function.
Additionally, PSEG applied a coating material to protect the area from further degradation.
The NRC inspectors did not identify any findings or violations of more than minor significance.
Observation: Semi-annual trend observation 71152S The inspectors performed a semi-annual review of site issues to identify trends that might indicate the existence of more significant safety concerns. As part of this review, the inspectors included repetitive or closely related issues documented by PSEG in their CAP database, trend reports, major equipment problem lists, system health reports, and maintenance or CAP backlogs. The inspectors recognized potentially developing trends related to PSEGs control and implementation of maintenance and work activities. These potential trends and examples of issues that inform them are outlined below.
Inspectors noted challenges related to control of spare and replacement parts:
- Emergency diesel generator relay parts were identified to have multiple material master (MMs) identifiers or the same part (20910406).
- Inconsistencies between actual parts and specified MMs, related to Swageloks, were identified (20909956).
- A review of critical MMs identified that 96 of 6000 critical MMs had no spare parts in stock (20915342).
- Fire protection component MMs were incorrectly classified as non-safety-related for procurement (PC4) (20916138).
- A HPCI diaphragm control valve diaphragm had multiple MMs which contributed to an incorrect part being installed (20919653).
Inspectors noted challenges related to control or performance of maintenance and work activities:
- The HPCI system turbine governor valve failed to open during testing after oil inlet and outlet lines were inadvertently switched during governor maintenance (20919466).
- An incorrect HPCI diaphragm was obtained (related to MM issue above) and installed which resulted in diaphragm failure during subsequent testing (20919653).
- Electrical jumpers were not removed as required by procedure prior to reactor mode changes made during startup from refueling outage RF24 (20913155).
- Flaws in condenser tubes were not identified during refueling outage RF24 maintenance activities, potentially contributing to subsequent chemistry control challenges (20918698).
Inspectors noted challenges related to work order record retention:
- Multiple work packages could not be located in records management systems (20912400, 20924320).
- Multiple records were not sent to records management in a timely manner (20915479, 20918099).
The NRC inspectors did not identify any findings or violations of more than minor significance during this review.
