Based on these initial screenings, the licensee initiated actions in the CAP to fully evaluate the impact, if any, to the station. When applicable, actions were developed and implemented in a timely manner to prevent similar issues from occurring. During interviews, licensee staff stated that operating experience lessons-learned were communicated during work briefings and department meetings and incorporated into plant operations. | Based on these initial screenings, the licensee initiated actions in the CAP to fully evaluate the impact, if any, to the station.

The inspectors identified one example where an audit/assessment finding was not properly addressed by the CAP. The Engineering Nuclear Assurance Audit Report PBN 21-022 was completed on February 22, 2021. As a result, AR 2386485 was generated due to the quarterly review of OE for Site Aging Management trends not being performed as prescribed by License Renewal Procedure EN-AA-206 Renewed Licensed Process. Assignment 1 of this AR was a Management Action to perform the quarterly aging management review, which was completed in the first quarter of 2021. In the completion notes, the licensee stated that it is the intention to continue submittals of quarterly LR reports going forward. The procedure was reviewed, and no procedural updates were deemed necessary at this time. Since the 2021 first quarter report, no quarterly reviews have been performed. During the inspection, the licensee stated that this review is a best practice activity and is not a license renewal commitment. The inspectors noted that the specific procedural instruction is a should statement to provide each AMP coordinator the discretion to perform or not perform quarterly reviews; however, as stated, the licensee's assessment concluded that these quarterly reviews were important and should continue. As a result of this inspection, AR 02434879 was initiated to document that the reviews were still not being performed. | The inspectors identified one example where an audit/assessment finding was not properly addressed by the CAP.

Workers expressed favorable opinions of the Employee Concerns Program (ECP) during interviews and stated that the on-site ECP manager routinely met with departments as part of an outreach effort. While most workers felt no need to engage the ECP, the inspectors noted that there were still several issues documented in the program. Through a selective review, the inspectors concluded that these issues were appropriately handled and identified no adverse trends. The inspectors did note however, that some of the system engineers were unaware of how to contact the ECP. Specifically, the licensee had begun locating all system engineering staff at their corporate headquarters. The engineers would remotely monitor fleet system status and periodically visit the individual sites to perform walk downs and other activities. The engineers were confused if they should reach out to their corporate or to the individual site ECP contacts. None of the interviewees stated to the inspectors that as a result some potential ECP issues were being unaddressed. The site ECP contact documented this issue in the CAP as AR 2435216. | Workers expressed favorable opinions of the Employee Concerns Program (ECP) during interviews and stated that the on-site ECP manager routinely met with departments as part of an outreach effort.

Observation: Trend of Charging Pump Relief Valve Failures on Unit 1 71152B The inspectors reviewed the licensees handling of several charging pump (CV) relief valve failures occurring over the past several years, primarily on Unit 1. These failures consisting of valves either leaking by or being stuck open, had been documented in several CAPs over the past 4 years. The licensee had identified this trend during an equipment failure investigation following the in-service test failure of the Unit 1 1CV-283B charging relief valve (ref AR 2401990, dated August 24, 2021.) In the review of the investigation and the prior test failures documented in the CAP, the inspectors had several observations including, but not limited to: | Observation: Trend of Charging Pump Relief Valve Failures on Unit 1 71152B The inspectors reviewed the licensees handling of several charging pump (CV) relief valve failures occurring over the past several years, primarily on Unit 1.

Although the licensee had identified that this failure trend primarily affected Unit 1, there was no specific action to identify or explain why this was the case; Each of the prior valve failures were apparently treated as a broke/fix in that the valves were replaced after failure and there were no apparent actions to identify and document the cause; In some cases, the failed valves were rebuilt after removal, however, there was no documentation in the CAP of any as found issues identified during the rebuilding; and There was no action to assess what the safety/risk impact of a relief valve failure would have on the plant. Although an operability assessment was performed following the failure of the 1CV-283A relief valve on March 27, 2021 (ref AR 2388101), the assessment only focused on this specific valve, was limited to the period between the test valve failure and subsequent replacement (i.e., 3 days), and was primarily focused on whether the event was reportable. | |||

During subsequent discussions with licensee engineering staff, the inspectors were able to ascertain that the licensee had an adequate understanding of the issue and were taking the appropriate actions. For example, in an apparent cause evaluation performed in 2006 (ref AR 1048091) following the failure of the Unit 2 2CV-283C relief valve, the licensee determined that low margin between the system pressure and the relief valve setpoint had resulted in these valves lifting and reseating. A corrective action was taken to revise station procedures to reduce the system backpressure to preclude this from occurring. Additionally, workers had documented observations in the valve rebuild packages showing signs of age-related degradation during the as found inspections. Based on this, the engineers believed that there was a finite period when these valves could be rebuilt and reused in the plant before losing functionality. This was supported by the fact that the valve failures comprising the recent trend on Unit 1 were all original construction that had been rebuilt several times over the plant life, which was apparently not the case on Unit 2. Subsequently, the licensee proposed actions to review the preventative maintenance program to determine when components could no longer be refurbished and warranted replacement. Based on the licensee's understanding of the issue, the proposed corrective actions, and a review of the valves' most recent performance and test history, the inspectors had no immediate safety concerns regarding these valves. | During subsequent discussions with licensee engineering staff, the inspectors were able to ascertain that the licensee had an adequate understanding of the issue and were taking the appropriate actions.

SUMMARY
The U.S. Nuclear Regulatory Commission (NRC) continued monitoring the licensees performance by conducting a biennial problem identification and resolution inspection at Point Beach Nuclear 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.
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.
OTHER ACTIVITIES - BASELINE
71152B - Problem Identification and Resolution Biennial Team Inspection (IP Section 03.04)
- (1) The inspectors performed a biennial assessment of the effectiveness of the licensees Problem Identification and Resolution program, use of operating experience, self-assessments and audits, and safety conscious work environment.
Problem Identification and Resolution Effectiveness: The inspectors assessed the effectiveness of the licensees Problem Identification and Resolution program in identifying, prioritizing, evaluating, and correcting problems. The inspectors also conducted a 5-year review of the units 1 and 2 auxiliary feedwater system.
Operating Experience: The inspectors assessed the effectiveness of the licensees processes for use of operating experience.
Self-Assessments and Audits: The inspectors assessed the effectiveness of the licensees identification and correction of problems identified through audits and self-assessments.
Safety Conscious Work Environment: The inspectors assessed the effectiveness of the stations programs to establish and maintain a safety-conscious work environment.
INSPECTION RESULTS
Assessment 71152B Effectiveness of Problem Identification
Overall, the station was effective at identifying issues at a low threshold and was properly entering them into the corrective action program (CAP) as required by station procedures.
During interviews, workers were familiar with how to enter issues into the CAP and stated that they were encouraged to use it to document issues. During plant walkdowns, the team observed that issues were being identified in the field and that they were being properly addressed in the CAP. The team determined that the station was generally effective at identifying negative trends that could potentially impact nuclear safety. For the areas reviewed, the team did not identify any issues in problem identification.
Effectiveness of Prioritization and Evaluation of Issues
In-depth reviews of a risk-informed sampling of action requests (ARs), work orders (WOs),and root and apparent cause and condition evaluations were completed. The team determined that the licensee had established a low threshold for entering deficiencies into the CAP, that the issues were generally being appropriately prioritized and evaluated for resolution, and that corrective actions (CAs) were implemented to mitigate the future risk of issues occurring that could affect overall system operability and/or reliability.
The inspectors noted that issues were properly screened with most either classified as Conditions Adverse to Quality (CAQ) or Non-Corrective Action Program (NCAP) items.
Through a selective review of CAP and NCAP items, the inspectors found no issues either with the assigned level of evaluation or the proposed corrective actions. Issues having potential operability concerns were properly addressed through the screening process and during control room observations and accompaniment of non-licensed operators during daily rounds, the inspectors did not identify any significant operator workarounds or similar deficiencies.
The inspectors also did a selective review of issues identified by the NRC either documented as observations, or for which findings or other enforcement was issued. These issues were properly documented and screened in the CAP.
Issue evaluations were generally sound and of good quality. Most issues were screened as low significance and were assigned a work group evaluation (the lowest level of review);more significant issues were assigned an apparent or if highly significant, a root cause evaluation. The inspectors verified that the assigned evaluations were consistent with the significance of the issue as defined in the licensees process.
The inspectors did identify one example where the licensee's screening process did not identify a potential Maintenance Rule Function Failure. Specifically, AR 02433655 was originated on August 5, 2022, for 2MS-2083-S, Unit 2 A Steam Generator Sample Isolation Valve. The valve was identified to be buzzing loudly, and when taken to close from the control room, the valve failed to close. The flow path was then isolated by securing instrument air to 2MS-2083 locally which caused the valve to shut. Since the solenoid valve failed to reposition when the control switch was closed, this rendered 2MS-2083 incapable of performing its specified safety function. A Maintenance Rule Evaluation was not determined to be required at this time. As a result of this inspection, AR 2434722 was initiated to document that the Maintenance Rule Performance Criteria for Containment Integrity includes a failure of a Containment Isolation Valve to close as a component failure. Recommended actions include reopening AR 02433655 to document the Maintenance Rule Evaluation.
Effectiveness of Corrective Actions
The team concluded that the licensee was generally effective in developing CAs that were appropriately focused to correct the identified problem and to address the root and contributing causes for significant conditions adverse to quality to preclude repetition. The licensee generally completed CAs in a timely manner and in accordance with procedural requirements commensurate with the safety significance of the issue. For NRC-identified issues, the team determined that the licensee generally assigned CAs that were effective and timely. The inspectors also did a selective review of CAs that were still open at least two years after the issue was identified to verify that it was appropriate for these items to remain open, and that the licensee was managing them correctly; no issues were identified.
Assessment 71152B The inspectors performed an expanded 5-year review of the Units 1 and 2 auxiliary feedwater system specifically, by performing system walkdowns, evaluating condition reports and work orders, and interviewing personnel responsible for working on the system. Overall, the inspectors determined that the licensee was effectively managing issues associated with this system.
No violations or findings were identified.
Assessment 71152B Assessment of Operating Experience and Self-Assessment and Audits Based on the samples reviewed, the team determined that licensee performance in the use of Operating Experience (OE) and Self-Assessments and Audits adequately supported nuclear safety.
No violations or findings were identified.
Use of Operating Experience The licensee routinely screened industry and NRC OE information for station applicability.
Based on these initial screenings, the licensee initiated actions in the CAP to fully evaluate the impact, if any, to the station. When applicable, actions were developed and implemented in a timely manner to prevent similar issues from occurring. During interviews, licensee staff stated that operating experience lessons-learned were communicated during work briefings and department meetings and incorporated into plant operations.
The inspectors identified one example of inadequate follow-up to industry OE. Specifically, as a follow up to NRC Information Notice (IN) 2007-21 Supplement 1, which was issued on December 11, 2020, AR 02378538 was issued to evaluate for applicability and potential changes to the site and/or fleet programs and processes. The IN 2007-21 Pipe Wear Due to Interaction of Flow-Induced Vibration (FIV) and Reflective Metal Insulation discussed instances of piping wear due to FIV conditions. This IN was determined to be applicable to Point Beach Unit 1 and 2. An Operating Experience Evaluation Form was completed. The evaluation determined Point Beach remains vulnerable until corrective actions are taken.
Unit 1 WO 40765001 was completed on April 2, 2022, with one identified condition documented and evaluated under AR 2423553 and WO 40822416. The initial recommendation from the OE evaluation was to perform the Unit 2 WO 40765002 during the outage in October 2021; however, the inspectors noted that this action remained unscheduled. The inspectors also noted that the action to schedule the Unit 2 inspection was at the discretion of the system engineer and was not formally tracked or reviewed under the CAP. The inspectors concluded that by not timely scheduling the Unit 2 work order, the licensee was not demonstrating the appropriate sensitivity to this issue, given that the OE evaluation concluded it was applicable and that a positive indication of FIV was identified on Unit 1. As a result, the licensee took action to schedule the Unit 2 WO for the next refueling outage, and initiated AR 2435191 to document this issue.
Self-Assessments and Audits
The inspectors reviewed several audits and self-assessments and deemed those sampled as thorough and intrusive with regards to following up with the issues that were identified.
The inspectors identified one example where an audit/assessment finding was not properly addressed by the CAP. The Engineering Nuclear Assurance Audit Report PBN 21-022 was completed on February 22, 2021. As a result, AR 2386485 was generated due to the quarterly review of OE for Site Aging Management trends not being performed as prescribed by License Renewal Procedure EN-AA-206 Renewed Licensed Process. Assignment 1 of this AR was a Management Action to perform the quarterly aging management review, which was completed in the first quarter of 2021. In the completion notes, the licensee stated that it is the intention to continue submittals of quarterly LR reports going forward. The procedure was reviewed, and no procedural updates were deemed necessary at this time. Since the 2021 first quarter report, no quarterly reviews have been performed. During the inspection, the licensee stated that this review is a best practice activity and is not a license renewal commitment. The inspectors noted that the specific procedural instruction is a should statement to provide each AMP coordinator the discretion to perform or not perform quarterly reviews; however, as stated, the licensee's assessment concluded that these quarterly reviews were important and should continue. As a result of this inspection, AR 02434879 was initiated to document that the reviews were still not being performed.
Assessment 71152B Assessment of Safety-Conscious Work Environment The team reviewed the stations programs to establish and maintain a safety-conscious work environment and interviewed station personnel to evaluate the effectiveness of these programs. Based on the teams observations and the results of these interviews, workers at the station expressed freedom to raise and enter safety concerns through any one of the various avenues available to them, and the team encountered no indications of chilling or retaliation.
Workers expressed favorable opinions of the Employee Concerns Program (ECP) during interviews and stated that the on-site ECP manager routinely met with departments as part of an outreach effort. While most workers felt no need to engage the ECP, the inspectors noted that there were still several issues documented in the program. Through a selective review, the inspectors concluded that these issues were appropriately handled and identified no adverse trends. The inspectors did note however, that some of the system engineers were unaware of how to contact the ECP. Specifically, the licensee had begun locating all system engineering staff at their corporate headquarters. The engineers would remotely monitor fleet system status and periodically visit the individual sites to perform walk downs and other activities. The engineers were confused if they should reach out to their corporate or to the individual site ECP contacts. None of the interviewees stated to the inspectors that as a result some potential ECP issues were being unaddressed. The site ECP contact documented this issue in the CAP as AR 2435216.
Overall, the inspectors found no evidence of challenges to the licensee's safety-conscious work environment, as licensee employees were willing to raise nuclear safety concerns through at least one of several means available.
No violations or findings were identified.
Observation: Trend of Charging Pump Relief Valve Failures on Unit 1 71152B The inspectors reviewed the licensees handling of several charging pump (CV) relief valve failures occurring over the past several years, primarily on Unit 1. These failures consisting of valves either leaking by or being stuck open, had been documented in several CAPs over the past 4 years. The licensee had identified this trend during an equipment failure investigation following the in-service test failure of the Unit 1 1CV-283B charging relief valve (ref AR 2401990, dated August 24, 2021.) In the review of the investigation and the prior test failures documented in the CAP, the inspectors had several observations including, but not limited to:
Although the licensee had identified that this failure trend primarily affected Unit 1, there was no specific action to identify or explain why this was the case; Each of the prior valve failures were apparently treated as a broke/fix in that the valves were replaced after failure and there were no apparent actions to identify and document the cause; In some cases, the failed valves were rebuilt after removal, however, there was no documentation in the CAP of any as found issues identified during the rebuilding; and There was no action to assess what the safety/risk impact of a relief valve failure would have on the plant. Although an operability assessment was performed following the failure of the 1CV-283A relief valve on March 27, 2021 (ref AR 2388101), the assessment only focused on this specific valve, was limited to the period between the test valve failure and subsequent replacement (i.e., 3 days), and was primarily focused on whether the event was reportable.
During subsequent discussions with licensee engineering staff, the inspectors were able to ascertain that the licensee had an adequate understanding of the issue and were taking the appropriate actions. For example, in an apparent cause evaluation performed in 2006 (ref AR 1048091) following the failure of the Unit 2 2CV-283C relief valve, the licensee determined that low margin between the system pressure and the relief valve setpoint had resulted in these valves lifting and reseating. A corrective action was taken to revise station procedures to reduce the system backpressure to preclude this from occurring. Additionally, workers had documented observations in the valve rebuild packages showing signs of age-related degradation during the as found inspections. Based on this, the engineers believed that there was a finite period when these valves could be rebuilt and reused in the plant before losing functionality. This was supported by the fact that the valve failures comprising the recent trend on Unit 1 were all original construction that had been rebuilt several times over the plant life, which was apparently not the case on Unit 2. Subsequently, the licensee proposed actions to review the preventative maintenance program to determine when components could no longer be refurbished and warranted replacement. Based on the licensee's understanding of the issue, the proposed corrective actions, and a review of the valves' most recent performance and test history, the inspectors had no immediate safety concerns regarding these valves.
Although the licensee appeared to have a good understanding of the issue, the inspectors noted that this knowledge was institutionalized among the engineers and station management, and was not captured in the CAP. Therefore, it was unclear whether this issue was being properly managed, as the lack of documentation made it difficult to verify resolution. For example, absent clear documentation, it was uncertain whether the issue was being evaluated by the appropriate licensee oversight processes, such as the Plant Health Committee. In addition, the lack of formal assignments in the CAP also made it uncertain whether the issue would be properly resolved. The licensee documented the inspectors concerns in AR 2435220, with proposed actions to capture the institutional knowledge in the CAP and to develop formal corrective actions, including determining which charging pump relief valves warranted replacement vs. rebuild, and performing an extent of condition for other plant components that were similarly refurbished.
No violations or findings were identified.
EXIT MEETINGS AND DEBRIEFS
The inspectors verified no proprietary information was retained or documented in this report.
On August 26, 2022, the inspectors presented the biennial problem identification and resolution inspection results to Mr. Bryan Woyak, and other members of the licensee staff.
