SUBJECT:

LASALLE COUNTY STATION, UNITS 1 AND 2NRC BIENNIAL PROBLEM IDENTIFICATION AND RESOLUTION INSPECTION REPORT 05000373/2019010 AND 05000374/2019010

Dear Mr. Hanson:

On April 26, 2019, the U.S. Nuclear Regulatory Commission (NRC) completed a problem identification and resolution inspection at your LaSalle County Station, Units 1 and 2 and discussed the results of this inspection with Mr. W. Trafton and other members of your staff.

The results of this inspection are documented in the enclosed report.

The NRC inspection team reviewed the stations corrective action program and the stations implementation of the program to evaluate its effectiveness in identifying, prioritizing, evaluating, and correcting problems, and to confirm that the station was complying with NRC regulations and licensee standards for corrective action programs. Based on the samples reviewed, the team determined that your staffs performance in each of these areas adequately supported nuclear safety.

The team also evaluated the stations processes for use of industry and NRC operating experience information and the effectiveness of the stations audits and self-assessments.

Based on the samples reviewed, the team determined that your staffs performance in each of these areas adequately supported nuclear safety.

Finally 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 the team found no evidence of challenges to your organizations safety-conscious work environment. Your employees appeared willing to raise nuclear safety concerns through at least one of the several means available. The NRC inspectors did not identify any finding or violation of more than minor significance.

This letter, its enclosure, and your response (if any) will be made available for public inspection and copying at http://www.nrc.gov/reading-rm/adams.html and at the NRC Public Document Room in accordance with 10 CFR 2.390, Public Inspections, Exemptions, Requests for Withholding.

SUMMARY

The U.S. Nuclear Regulatory Commission (NRC) continued monitoring the licensees performance by conducting a problem identification and resolution inspection at LaSalle County Station, Units 1 and 2 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. Findings and violations being considered in the NRCs assessment are summarized in the table below.

List of Findings and Violations

No findings 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 02.04)

The inspectors performed a biennial assessment of the licensees corrective action program, use of operating experience, self-assessments and audits, and safety conscious work environment.

  • Corrective Action Program Effectiveness: The inspectors assessed the corrective action programs effectiveness in identifying, prioritizing, evaluating, and correcting problems.
  • Operating Experience, Self-Assessments and Audits: The inspectors assessed the effectiveness of the stations processes for use of operating experience, 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 Corrective Action Program: Based on the samples reviewed, the inspectors determined that staffs performance in each of these areas adequately supported nuclear safety.

Effectiveness of Problem Identification: Overall, the licensee was effective at identifying issues at a low threshold and was properly entering them into the Corrective Action Program (CAP) as required by procedures. The inspectors determined that the station was generally effective at identifying negative trends that could potentially impact nuclear safety. The inspectors did several plant walkdowns; for the areas reviewed, the inspectors did not identify any concerns in the area of 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 cause evaluations were completed, including a 5 year review of issues associated with the Switchgear Heat Removal (VX) system. The inspectors identified that the licensee generally, appropriately prioritized and evaluated issues for resolution.

The inspectors identified several examples where the issue documentation was insufficient to clearly understand the actions taken to evaluate and resolve the issues. One of the expectations in the licensees CAP program procedure was that each CAP item be sufficiently documented to function as a stand alone product. Specifically, that an independent reader could clearly understand the issue and how it was evaluated and corrected. This expectation was supposed to be reinforced by the Station Oversight (SOC) and Management Review (MRC) Committees, who were responsible for screening each CAP issue. A similar observation had also been identified in the most recent and previous Nuclear Oversight (NOS)audits of the program. Although the inspectors were able to verify that the associated issues were properly addressed, this appeared to be an ongoing issue warranting further licensee attention. The licensee documented this observation in the CAP.

Effectiveness of Corrective Actions: The inspectors concluded that the licensee was generally effective in developing Corrective Actions that were appropriately focused to correct the identified problem and correct conditions adverse to quality. For issues considered significant conditions adverse to quality, the licensee took action to address the root and contributing causes and to preclude repetition. Corrective actions were generally completed in a timely manner and in accordance with procedural requirements commensurate with the safety significance of the issue.

The inspectors reviewed a root cause to address fuel channel distortion issues documented in AR 4169154. This issue was considered a Condition Adverse to Quality. The corrective action for this concern was to transition to advanced channel materials, that were less susceptible to this distortion, by 2023. As interim actions, the licensee had initiated rechanneling of fuel bundles, equipment inspections, revising the channel friction model and updating the channel distortion monitoring plan. As stated in the root cause, these interim actions were designed to mitigate the risk of fuel channel distortion until the final actions were completed. However, the inspectors noted that these items were coded as action tracking items (ACITs), instead of corrective actions in the CAP. The ACITs were considered a lower classification than a corrective action, meaning that they could be cancelled, rescheduled or modified without station management review. Another example was AR 1136071, documenting a potential non-conservative Technical Specification applicable to LaSalle station, which was also considered a Condition Adverse to Quality. One of the interim actions, was to track the NRC review of an industry document which recommended actions to address this concern. Upon competition of the NRC review, the licensee planned to implement these recommendations as the final corrective action. However, this interim action was tracked as an ACIT rather than as a corrective action. As a result, even though the NRC review was completed in 2017, the ACIT did not show up as overdue, given its lower priority status, until the inspectors brought it to the attention of the licensee. Based on interviews, the inspectors determined that the practice of using ACITs was in part due to a misconception among licensee staff, that since the interim actions were not the final corrective actions, they did not warrant such coding. However, since these interim actions were designed to mitigate the risk until the final actions were implemented, the inspectors determined that they should be treated as corrective actions. By coding them as ACITS, the inspectors concluded that this may result in some Conditions Adverse to Quality not being adequately addressed. The licensee documented this observation in the CAP.

The inspectors also identified examples where risk assessments were not being performed in accordance with the CAP procedures. Each of these examples were classified as Conditions Adverse to Quality. This was in part due to unclear guidance regarding what constituted an appropriate risk assessment and the lack of reinforcement of this expectation during CAP product screenings. For example, the root cause evaluation for AR 4193000, concluded that inadequate oversight by mid-level management was a primary contributor in several equipment failures occurring at the site. Under the CAP procedure, each root cause was required to have either a Corrective Action to Prevent Recurrence (CAPR) or a risk assessment, if a CAPR was not assigned. For this issue, there was no documented CAPR or risk assessment. Similarly, the licensee CAP procedures required that for Corrective Action Program Evaluations (CAPEs; formally referred to as Apparent Cause Evaluations), if a cause was not identified, then the most probable cause should be documented and a risk assessment performed. The inspectors identified two CAPEs (ARs 4110933; 4117722) for which no cause was identified, but there was no stated probable cause or risk assessment documented. Based on interviews with those licensee staff involved in the above evaluations, the inspectors determined that the risk had been considered, even though the licensee procedural requirements were not strictly followed. Also, in all of the examples, the licensee had implemented interim actions which the inspectors reviewed and concluded were sufficient to address the concern and mitigate the risk; however, these actions were documented as ACITs and not corrective actions. Since the intent of the procedure, if not necessarily the strict requirements were met, this was not considered a violation, however, the inspectors concluded that this was a failure to reinforce CAP expectations and requirements. This licensee documented this issue in the CAP.

No corrective action program issues were identified during the review of the VX system.

As stated, the observations identified by the inspectors were documented in the licensee CAP.

The specific ARs are listed in the attached List of Documents Reviewed for this inspection.

Assessment 71152B Operating Experience and Self-Assessment and Audits: Based on the samples reviewed, team determined that the licensees performance in each of these areas adequately supported nuclear safety.

The team noted that Operating Experience identified by external organizations, such as industry groups and the NRC, were appropriately addressed by station procedures.

Specifically, there was prescriptive guidance regarding how these items were to be tracked, documented and processed in the CAP. However, the inspectors noted that similar guidance was not prescribed for Operating Experience identified through internal corporate oversight.

For example, the licensees corporate organization had identified a potential fleet trend involving configuration control events. This trend was captured as a corporate CAP and several actions were identified to be taken by each of the individual plants in the fleet.

However, there was no documentation or evidence of any tracking items ensuring that the actions were taken at each site (including LaSalle) nor was there any assessment of their effectiveness in addressing the trend. As a result, these types of issues were not processed similarly to those originating from the industry. The licensee documented this observation in the CAP. The specific CAP item is documented in the List of Documents Reviewed that is attached to this report.

Assessment 71152B Safety Conscious Work Environment (SCWE): The inspectors found no significant challenges to the licensees organizations safety conscious work environment. Through interviews and field observations, the inspectors determined that workers were willing to identify issues through any of the available means and had generally positive feedback on the program effectiveness. The overall health of the Employee Concerns Program was good and no adverse, discernible trend was noted during the review of issues.

One area of focus was the stations use of the OR7 code to classify issues having potential safety culture concerns. Individuals whose issues were assigned this code, were to be contacted by supervision to discuss the issue and assess the impact. During interviews, most individuals had only a general awareness of this code with some expressing concerns that it was potentially detrimental--i.e., the code could be used to identify complainers; however, none of the individuals expressed any reluctance to raise issues. The inspectors noted that the station had identified a similar concern and had initiated a CAP item (AR 4237390) to address this issue.

Overall the licensee was maintaining an appropriate safety conscious and work environment.

EXIT MEETINGS AND DEBRIEFS

The inspectors verified no proprietary information was retained or documented in this report.

  • On April 26, 2019, the inspector presented the problem identification and resolution inspection results to Mr. W. Trafton and other members of the licensee staff.
