SUMMARY

The U.S. Nuclear Regulatory Commission (NRC) continued monitoring the licensees performance by conducting a Problem Identification and Resolution Inspection at St. Lucie Plant, 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.

List of Findings and Violations No findings were identified.

INSPECTION SCOPE

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.

REACTOR SAFETY

71152B - Problem Identification and Resolution

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. The assessment is documented below.

(1) Corrective Action Program Effectiveness: Problem Identification, Problem Prioritization and Evaluation, and Corrective Actions - The 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.
(2) Operating Experience and Self-Assessments and Audits - The team evaluated the stations processes for use of industry and NRC operating experience information and the effectiveness of the stations audits and self-assessments.
(3) 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.

INSPECTION RESULTS

Corrective Action Program Effectiveness Observations 71152Problem Identification and Resolution Based on the samples reviewed, the team determined that the licensees corrective action program (CAP) complied with regulatory requirements and self-imposed standards. The licensees implementation of the CAP adequately supported nuclear safety.

Effectiveness of Problem Identification: The inspectors determined that the licensee was effective in identifying problems and entering them into the CAP and there was a low threshold for entering issues into the CAP. This conclusion was based on a review of the requirements for initiating Condition Reports (CRs) as described in licensee procedure PI-AA-104-1000, Condition Reporting, and managements expectation that employees were encouraged to initiate CRs for any reason. Additionally, site management was actively involved in the CAP and focused appropriate attention on significant plant issues.

Based on reviews and walkdowns of accessible portions of selected systems, the inspectors determined that deficiencies were being identified and placed in the CAP.

Effectiveness of Prioritization and Evaluation of Issues: Based on the review of CRs sampled by the inspection team during the onsite period, the inspectors concluded that problems were generally prioritized and evaluated in accordance with the CR significance determination guidance in procedure PI-AA-104-1000. The inspectors determined that in general, adequate consideration was given to system or component operability and associated plant risk.

The inspectors determined that plant personnel had conducted root cause and apparent cause analyses in compliance with the licensees CAP procedures and cause determinations were appropriate, and considered the significance of the issues being evaluated. A variety of formal causal-analysis techniques were used to evaluate CRs depending on the type and complexity of the issue consistent with the applicable cause evaluation procedures.

The inspection team identified one issue of concern regarding the failure to properly consider mission time of Emergency Diesel Generators (EDGs) in operability evaluations in accordance with Procedure EN-AA-203-1001, Operability Determinations / Functionality Assessments, Revision 29. This issue was entered into the licensees CAP as CR 2264338 and is documented as a minor performance deficiency in the section below.

Effectiveness of Corrective Actions: Based on a review of corrective action documents, interviews with licensee staff, and verification of completed corrective actions, the inspectors determined that overall, corrective actions were timely, commensurate with the safety significance of the issues, and effective, in that conditions adverse to quality were corrected.

For significant conditions adverse to quality, the corrective actions directly addressed the cause and effectively prevented recurrence. The team reviewed performance indicators, CRs, and effectiveness reviews, as applicable, to verify that the significant conditions adverse to quality had not recurred. Effectiveness reviews for corrective actions to prevent recurrence (CAPRs) were sufficient to ensure corrective actions were properly implemented and were effective.

Minor Performance Deficiency 71152Problem Identification and Resolution Minor Performance Deficiency: The station failed to properly consider mission time of EDGs in operability evaluations in accordance with Procedure EN-AA-203-1001. Specifically, as documented in several CRs, the conclusions provided within the operability analysis sections could not be supported without evaluating the conditions against the system mission time.

The inspectors reviewed CRs 2132695, 2132704, and 2132705, which were all initiated to document oil leaks on the EDGs. Each CR contained a statement that, there is no impact on the ability of the EDG to meet its mission time, under the operability notes.

The inspectors reviewed the EDG Design Basis Documents (DBD-EDG-1, -2) for the defined mission time and determined that an official mission time had not been established for the EDGs. The inspectors interviewed a sample of senior reactor operators and determined that the mission time used for operability determinations had been a loosely based time derived from EDG placards and day tanks and diesel oil storage tank capacities.

Procedure EN-AA-203-1001 governed operability determinations at St. Lucie Plant. Step 4.2.2.2 directed that the screener of a condition report shall perform the Operability/Functionality Review screening using guidance in Attachment 1. Step 6, Table C of Attachment 1 required the screener to evaluate that the condition did not impair completion of design mission time.

For issues that required immediate operability determinations, Step 4.3.6 directed the Shift Manager to prepare the Immediate Operability Determination using the guidance of 2, Immediate Operability Determination Guidelines. Attachment 2, Step 2 stated:

In order to be considered operable, a SSC must be capable of performing the specified safety functions of its design, within the required range of physical conditions, initiation times, and mission times assumed in the CLB. For operability determination purposes, the mission time was the duration of SSC operation that was credited in the design basis for the SSC to perform its specified safety function.

In addition, Attachment 2, Step 8, stated: If oil leakage is detected from either a pump bearing housing, a motor bearing housing, or a governor, then leakage rate and mission time must be addressed.

Contrary to the above, because a mission time had not been established in the EDG Design Basis Documents (DBD-EDG-1, -2) for the EDGs, the ability of the system to remain operable for the duration of its mission time had not been appropriately evaluated for several conditions associated with EDGs.

CR 2264338 was originated to address the issue. The licensee had initiated actions to establish an official EDG mission time within the Design Basis Documents and perform an extent of condition to determine if a mission time needed to be established for other plant systems.

Screening: The inspectors screened the issue in accordance with Inspection Manual Chapter 0612, Appendix B, Issue Screening, and determined that the performance deficiency did not meet the criteria in Block 3 to be a More-than-Minor issue. The inspectors determined that the CRs reviewed for this instance were minor in nature and therefore would unlikely change the outcome of the operability determinations of the examples reviewed. The inspectors did not identify a violation of regulatory requirements associated with this minor performance deficiency.

Operating Experience and Self-Assessments and Audits Observations 71152Problem Identification and Resolution Based on the samples reviewed, the team determined that stations processes for the use of industry and NRC operating experience information and for the performance of audits and self-assessments were effective and complied with all regulatory requirements and licensee standards. The implementation of these programs adequately supported nuclear safety.

Overall, the team concluded that operating experience was adequately evaluated for applicability and that appropriate actions were implemented to address lessons learned as needed. In general, the inspectors determined that the licensee was effective at performing self-assessments and audits to identify issues at a low level, properly evaluated those issues, and resolved them commensurate with their safety significance.

Safety Conscious Work Environment Observations 71152Problem Identification and Resolution Based on interviews with plant staff and reviews of the latest safety culture survey results to assess the safety-conscious work environment on site, the team found no evidence of challenges to safety-conscious work environment. Employees appeared willing to raise nuclear safety concerns through at least one of the several means available.

EXIT MEETINGS AND DEBRIEFS
