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 at approximately 80 percent rated thermal power (RTP) for end-of-cycle coastdown. On April 21, Hope Creek commended a shutdown for scheduled refueling outage H1R23. Hope Creek remained offline for the refueling outage until May 14, when the unit began startup and reached 100 percent RTP on May 17. On May 24, Hope Creek commenced a shutdown for a maintenance outage to replace 'A' and 'B' recirculation pump seals following indications of degraded inner pump seals and replace the 'R' safety relief valve (SRV) assembly following indications of pilot valve leakage. Following the maintenance outage, Hope Creek returned to 100 percent RTP on May 29. On June 16, the 'B' reactor feedwater pump tripped due to a blown fuse, resulting in the 'A' and 'B' recirculation intermediate runback to 70 percent RTP as expected for the given condition. Following the corrective maintenance, Hope Creek returned to 100 percent RTP later that day. On June 27, Hope Creek commenced a shutdown and maintenance outage to replace the 'A' SRV following identification of pilot leakage. Hope Creek began startup on June 29 and were in power ascension until 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 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), resident and regional inspectors were directed to begin telework and to remotely access licensee information using available technology. During this time, the resident inspectors performed periodic site visits each week, increasing the amount of time on site as local COVID-19 conditions permitted.

As part of their onsite activities, resident inspectors conducted plant status activities as described in IMC 2515, Appendix D; observed risk significant activities; and completed on site portions of IPs. In addition, resident and 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.

INSPECTION RESULTS

Observation: Observation: Semi-Annual Trend Review for PSEGs CAP for 71152 trends that might be indicative of a more significant safety issue The inspectors reviewed Hope Creeks corrective action program (CAP) for trends that might be indicative of a more significant safety issue. Specifically, the inspectors reviewed Significant Level 1 through Significant Level 5 notifications (NOTF) for the time period of November 1, 2020 through May 31, 2021.

The inspectors evaluated several NOTFs generated during this time period by departments that provide input to the quarterly trend reports. The inspectors determined that, in most cases, issues were appropriately evaluated by PSEG staff for potential trends and resolved within the scope of the CAP. However, the inspectors noted a few instances where PSEG did not recognize or consider, until prompted by inspectors, that potential adverse trends existed. Examples of this are documented below:

1) Multiple issues across Emergency Diesel Generators (EDGs)

  • NOTF 20864137 in December 2020 for A EDG lube oil breaker tripping, with follow on NOTFs 20867358 and 20864146.
  • NOTF 20867194 in December 2020 A EDG jacket water temperature low alarm.
  • NOTFs 20871675 and 20871962 in March 2021 for B EDG jacket water keep warm temperature high.
  • NOTFs 20871719 and 20874405 in March and April 2021 for D EDG lube oil crankcase containing high water content.
  • NOTF 20876482 in May 2021 for B EDG rocker arm lube oil (RALO) containing high silicon content.

2) Main Control Room Chiller Repetitive Issues

  • NOTF 20868302 in January 2021 documented the preventive strategy for the A main control room chiller based on overall performance and subject matter expert feedback.
  • NOTF 20875758 on April 25, 2021 for the AK400 chiller trending higher for chilled water outlet temperature compared to the setpoint. This was a repetitive NOTF to NOTF 20869541 from February 2021.
  • NOTF 20875718 on April 27, 2021 for the AK400 chiller low oil pressure trip.
  • NOTF 20872994 on April 28,2 021 for AK400 chiller tripping on high oil level following restoration from low oil pressure trip. The total oil removed from the system was 4.5 gallons. There were no documented corrective actions to determine why the 4.5 gallons of oil needed to be removed following a AK400 chiller trip on low oil level prior to the trip for high oil level.
  • NOTF 20876449 on May 5, 2021 for A control room vent train, AK 400 chiller, tripped twice via the failure of the 1A-P-412 A control room chiller lube oil pump motor.
  • NOTF 20876471 on May 6, 2021 for the BK400 chiller tripped on low evaporator pressure shortly after being placed in service. The BK400 chiller was previously identified as being low on refrigerant following a B control room vent train trip on March 25, 2021, with refrigerant added on March 26, 2021.

The inspectors reviewed LS-AA-125-1006, Revision 8, Integrated Performance Assessment, for how Hope Creek would capture trends in CAP. Specifically, Step 4.2.3 for SAP trend coding applies at least one applicable SAP trend code from a provided code group. Additionally, Step 4.2.6 states, submit notification for potential adverse trends identified through cognitive analysis. Currently, Hope Creek is not tracking an adverse trend in CAP for equipment performance on either the EDGs or main control room chillers. The inspectors review determined there is a potential adverse trend in equipment performance for the EDGs and main control room chillers. Specifically, the NOTFS for oil content on multiple EDGs and the multiple trips of the main control room chillers represent an adverse trend in equipment performance.

Hope Creek has been tracking and trending oil samples for the EDGs and capturing the moisture content intrusion via the referenced NOTFs. Hope Creek has performed multiple equipment reliability evaluations to determine the cause and impact of the water intrusion. Additionally, Hope Creek have or will implement planned corrective actions for these respective EDG oil reservoirs during scheduled maintenance windows.

Hope Creek also evaluated lessons learned from the chiller challenges documented in the referenced NOTFs. Hope Creek has implemented additional monitoring for the oil levels and oil-bearing temperatures based on the time of the year and additional operator alarms. Additionally, Hope Creek is assessing design changes to improve chiller performance and has in place a preventive maintenance strategy focusing on the labyrinth seals to improve oil migration.

The inspectors determined PSEGs overall response to the issues were commensurate with the safety significance and included appropriate corrective actions. The inspectors determined PSEGs corrective actions were reasonable and timely to evaluate and correct the conditions. The inspectors did not identify any performance deficiencies based on the review.
