SUMMARY

The U.S. Nuclear Regulatory Commission (NRC) continued monitoring the licensees performance by conducting an integrated inspection at Brunswick Steam Electric Plant, 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

Unit 1 began the period shutdown for a refueling outage. On April 2, 2022, the reactor was taken critical and a plant startup was commenced. On April 4, the main generator output breaker was closed and a power ascension was commenced. On April 5, power was stabilized at 30 percent rated thermal power (RTP) in order to perform condenser dimple plug testing to locate leaking water-box tubes. Following completion of dimple plug testing, a power ascension was commenced and Unit 1 reached 100 percent (full) RTP on April 15 following two rod improvements. Unit 1 continued to operate at full RTP until April 19 when power was reduced to 96 percent RTP due to a failure of a cell in the variable frequency drive (VFD) associated with the 'B' recirculation pump motor. Following the bypass of the 1B2 cell in the 'B' VFD, Unit 1 was restored to full RTP on the same day and continued to operate there until May 19 when power was reduced to 80 percent RTP due to a loss of one of the four Unit 1 off-site power lines (Weatherspoon). Following repairs to the Weatherspoon line, Unit 1 was restored to full RTP on May 21 and continued to operate at or near full RTP for the remainder of the inspection period.

Unit 2 began the period at full RTP and operated there until May 7, when power was reduced to 70 percent RTP in order to insert a second suppression rod due to an existing fuel leak. Following insertion of a second suppression rod, Unit 2 was restored to full power on May 8 and continued to operate there until May 20 when power was reduced to 70 percent RTP for the purpose of performing a control rod sequence exchange as well as insert a third suppression rod. Following the sequence exchange and suppression rod insertion, Unit 2 was restored to full RTP on May 25 following one rod improvement. Unit 2 continued to operate at or near full 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.

INSPECTION RESULTS

Observation: Reactor Recirculation Pump Seal Premature Failure 71152A The inspectors conducted a detailed review of NCR 2379462, Reactor Recirculation Pump Seal Premature Failure. The inspectors chose this sample because it dealt with the barrier integrity cornerstone involving the recirculation pump seals. On February 15, 2021, the second stage seal of the Unit 2 'B' recirculation pump was noted to be degrading. Based on the rate of degradation, the decision was made to replace the seal package during the upcoming March 2021 refueling outage. Following replacement of both the 'A' and 'B' seal packages during the refueling outage, operators noted a similar degrading second stage seal on the Unit 1 'B' recirculation pump on April 19, 2021. The decision was made to enter a maintenance outage on April 30 as the rate of seal degradation was excessive and the seal would not last until the next refueling outage in March 2022. The recirculation pump seals have an expected life of six years, yet the inspectors observed that the seals are degrading prior to reaching the end of their expected life cycle.

The licensee performed a detailed root cause analysis in order to understand the failure mechanism and develop corrective actions to address the deficiencies. The root cause was determined to be self-induced electro-corrosion of the second stage secondary seal. Several corrective actions have been implemented including the replacement of all 4 seals on both units. The inspectors noted that this will be a long-term effort as the design changes to address the direct cause of the electro-corrosion are still being developed. The inspectors determined that the licensees plan to address this issue was reasonably commensurate with the safety significance of the equipment that might be affected by this type of equipment failure.

Observation: Semi-Annual Trend Review 71152S The inspectors performed a trend analysis on the licensees corrective action program to identify trends that could indicate the existence of a more significant safety issue. The inspectors focused their review on equipment performance trends, but also considered the results of inspector daily condition report screenings, licensee trending efforts, and licensee human performance results. The review nominally considered the 6-month period of January

- June 2022, although some examples extended beyond those dates when the scope of the trend warranted. The inspectors compared their results with the licensees analysis of trends.

Additionally, the inspectors reviewed the adequacy of corrective actions associated with a sample of the issues identified in the licensees trend reports. The inspectors also reviewed corrective action documents that were processed by the licensee to identify potential adverse trends in the condition of structures, systems, and/or components as evidenced by acceptance of long-standing non-conforming or degraded conditions.

During this review, the inspectors noted the reemergence of a negative trend with respect to reactor fuel performance. In Brunswick inspection report 05000324/2019002 and 05000325/2019002 (ADAMS Accession No. ML19221B744), the inspectors noted a negative trend based on three separate fuel cycles experiencing fuel failures. Following these failures, the licensee aggressively addressed the failures by performing detailed root cause evaluations. No definitive cause was noted. However, some of the failures were attributed to potential negative effects from foreign material. Additionally, one failure was attributed to a manufacturing defect. In order to address the foreign material, the license chose to clean all fuel assemblies during the upcoming refueling outages as well as perform a foreign object search and retrieval (FOSAR) activity. As of June 30, 2022, the fuel cleaning and FOSAR activities have been completed on both Unit 1 and Unit 2 during the most recent refueling outages. Since the initial determination of a negative trend in 2019, the inspectors noted two more cycles (Unit 1 in 2020 and Unit 2 in 2022) where fuel failures were encountered.

Despite the fuel cleaning and FOSAR efforts, Unit 2 recently experienced another fuel failure in April 2022 which necessitated flux suppression. Even given the flux suppression, the Unit 2 reactor coolant system activity has remained elevated. In summary, the condition reports (CRs) noted below document that five of the past seven fuel cycles on Unit 1 and Unit 2 experienced fuel leaks. Fuels leaks typically drive the licensee to suppress the neutron flux of the affected fuel assembly by inserting control rod(s) in the vicinity of the fuel leak. The inserted control rod can result in reduction of margin to thermal limits, limit rates of power increase, and increase the number of rod programming changes. The inspectors discussed this negative trend with the licensee.
