SUBJECT:

SOUTH TEXAS PROJECT ELECTRIC GENERATING STATION, UNITS 1 AND 2 - BIENNIAL PROBLEM IDENTIFICATION AND RESOLUTION INSPECTION REPORT 05000498/2022010 AND 05000499/2022010

Dear Mr. Powell:

On June 24, 2022, the U.S. Nuclear Regulatory Commission (NRC) completed a problem identification and resolution inspection at your South Texas Project Electric Generating Station, Units 1 and 2. On June 30, 2022 the NRC inspectors discussed the results of this inspection with you and other members of your staff. The results of this inspection are documented in the enclosed report. The report is comprised of two enclosures. Enclosure 1 contains the publicly available version of the inspection report and Enclosure 2 contains the Official Use Only -

Security Related Information portions of the inspection report.

The NRC inspection team reviewed the stations problem identification and resolution 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 problem identification and resolution programs.

Based on the samples reviewed, the team determined that your staffs performance in each of these areas adequately supported nuclear safety. However, the team identified a weakness associated with evaluating adverse conditions associated with security-related issues. The specifics of the weakness are discussed in Enclosure 2.

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 upon the interviews and document reviews, the team found that your organization had a safety conscious work environment where individuals felt free to raise safety Enclosure 2 transmitted herewith contains SUNSI.

OFFICIAL USE ONLY - SECURITY-RELATED INFORMATION 2

OFFICIAL USE ONLY - SECURITY-RELATED INFORMATION 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 Sample)

(1) 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. The inspectors sampled over 240 condition reports and their associated cause evaluations, if applicable. The inspectors also conducted a five-year review of the component cooling water system, which included review of failures, maintenance issues, surveillances, corrective and preventive maintenance, reliability, and maintenance rule performance. In addition, the inspectors reviewed 17 NRC findings and violations issued during the biennial period.

Operating Experience, Self-Assessments and Audits: The inspectors assessed the effectiveness of the stations processes for use of operating experience, audits and self-assessments. The sample included industry operating experience communications like 10 CFR Part 21 notifications and other vendor correspondence, NRC generic communications, publications from various industry groups, and site evaluations. The sample also included reviews of licensee self-assessments and internal audits.

Safety Conscious Work Environment: The inspectors assessed the effectiveness of the stations programs to establish and maintain a safety conscious work environment. The team interviewed 65 individuals, observed interactions between licensee employees and management during routine meetings, interviewed the employee concerns program manager and reviewed employee concerns files.

OFFICIAL USE ONLY - SECURITY-RELATED INFORMATION 3

OFFICIAL USE ONLY - SECURITY-RELATED INFORMATION INSPECTION RESULTS Assessment 71152B Corrective Action Program Assessment Based on the samples reviewed, the team determined that the licensees corrective action program complied with regulatory requirements and self-imposed standards. The licensees performance in each of the areas of Problem Identification, Problem Prioritization and Evaluation, and Corrective Actions adequately supported nuclear safety.

Effectiveness of Problem Identification: Based on the samples reviewed, the team determined that the licensee's performance in this area adequately supported nuclear safety. Overall, the team found that the licensee was identifying and documenting problems at an appropriately low threshold that supported nuclear safety.

Effectiveness of Prioritization and Evaluation of Issues: Overall, the team found that the licensee was appropriately prioritizing and evaluating issues to support nuclear safety. Of the samples reviewed, the team generally found that the licensee correctly characterized each condition report as to whether it represented a condition adverse to quality, and then prioritized the evaluation and corrective actions in accordance with program guidance.

However, the team identified a weakness associated with evaluating adverse conditions associated with security-related issues. This weakness is described further in Enclosure 2 to this report.

Effectiveness of Corrective Actions: Overall, the team concluded that the licensee's corrective actions supported nuclear safety. Specifically, the STP Nuclear Operating Company developed effective corrective actions for the problems evaluated in the corrective action program and generally implemented these corrective actions in a timely manner commensurate with their safety significance. As part of this inspection, the team selected the plants component cooling water system for a focused review within the corrective action program. For this system, the team performed sample selections of condition reports, looking at the adequacy of the licensee's evaluation process for determining which items are placed in the corrective action process, and the corrective actions taken. The team did not identify any concerns with this system that were not already being addressed by the station's monitoring and corrective action programs.

Assessment 71152B Use of Self-Assessment & Audits The team reviewed a sample of STP Nuclear Operating Company's departmental self-assessments and audits to assess whether performance trends were regularly identified and effectively addressed. The team also reviewed audit reports to assess the effectiveness of assessments in specific areas. Overall, the team concluded that the licensee had an adequate departmental self-assessment and audit process.

Assessment 71152B Use of Operating Experience OFFICIAL USE ONLY - SECURITY-RELATED INFORMATION 4

OFFICIAL USE ONLY - SECURITY-RELATED INFORMATION The team reviewed a variety of sources of operating experience including part 21 notifications and other vendor correspondence, NRC generic communications, publications from various industry groups. The team determined that STP Nuclear Operating Company is adequately screening and addressing issues identified through operational experience that apply to the station and that this information is evaluated in a timely manner once it is received.

Assessment 71152B Safety Conscious Work Environment (SCWE)

The team conducted safety conscious work environment interviews with 65 employees from five different disciplines that included operations, security, mechanical maintenance, electrical maintenance and instrumentations and controls maintenance. The purpose of these interviews was (1) to evaluate the willingness of the licensee staff to raise nuclear safety issues, either by initiating a condition report or by another method, (2) to evaluate the perceived effectiveness of the corrective action program at resolving identified problems, and (3) to evaluate the licensee's safety conscious work environment (SCWE). The team also observed interactions between employees during routine condition report screening committee meetings, plant management alignment meetings, management performance improvement committee meetings, and plant health committee meetings. The team interviewed the employee concerns program manager and reviewed the results of the latest safety culture surveys and a sample of case files that may relate to safety conscious work environment.

Based upon the interviews and document reviews, the team found that the licensee had a safety conscious work environment where individuals felt free to raise safety concerns without fear of retaliation. However, the team identified that multiple individuals in the Security department indicated a strong hesitancy in bringing up concerns to some members of management at the site. In addition, some of these individuals expressed mixed experiences raising issues through the corrective action program and the employee concerns program. All individuals indicated that they would not hesitate to raise safety concerns through at least one of the means available. The team also noted that the individuals in the Security department described low morale concerns, which appear to be caused by factors such as low staffing levels, perceived inconsistencies in management actions, long time security equipment material condition issues, and an uneasiness toward managements reaction to their concerns. The team concluded that if not addressed, these morale concerns could erode the individuals willingness to bring up safety or security concerns in the future.

Failure to use the site corrective action program to correct failures and deficiencies in the physical protection program.

Cornerstone Significance Cross-Cutting Report Aspect Section Security Green [H.1] - 71152B NCV 05000498,05000499/2022010-01 Resources Open/Closed The NRC identified a Green non-cited violation of 10 CFR 73.55(b)(10) for the failure to use the site corrective action program to correct and prevent recurrence of failures and deficiencies in the physical protection program. This non-cited violation is described in of this report.

CR-22-6335 Performance Assessment:

Performance Deficiency: The failure to use the site corrective action program to correct failures and deficiencies in the physical protection program is a performance deficiency. It is a performance deficiency because the licensee failed to meet 10 CFR 73.55(b)(10), and it was within the licensees ability to reasonably foresee and correct and should have been prevented.

Screening and Significance: The screening for and significance of this non-cited violation are documented in Enclosure 2 of this report.

Cross-Cutting Aspect: H.1 - Resources: Leaders ensure that personnel, equipment, procedures, and other resources are available and adequate to support nuclear safety.

Specifically, the site corrective action procedures did not adequately define security conditions adverse to quality.

Enforcement:

Violation: 10 CFR 73.55(b)(10) states, The licensee shall use the site corrective action program to track, trend, correct and prevent recurrence of failures and deficiencies in the physical protection program. The violation details are documented in Enclosure 2 of this inspection report.

Enforcement Action: This violation is being treated as a non-cited violation, consistent with Section 2.3.2 of the Enforcement Policy.

Observation: Failure to properly categorize security-related issues as conditions 71152B adverse to quality As part of the weakness associated with evaluating adverse conditions in security-related issues described in the Assessment in this inspection report, the inspectors identified multiple examples where condition reports associated with security material condition issues were mischaracterized as conditions not adverse to quality.

This Observation is described in Enclosure 2 of this report.

EXIT MEETINGS AND DEBRIEFS The inspectors verified no proprietary information was retained or documented in this report.
