SHEARON HARRIS NUCLEAR POWER PLANT - NRC PROBLEM IDENTIFICATION AND RESOLUTION INSPECTION REPORT 05000400/2013007
Dear Mr. Kapopoulos:
On August 22, 2013, the U. S. Nuclear Regulatory Commission (NRC) completed a Problem Identification and Resolution inspection at your Shearon Harris Nuclear Power Plant Unit 1. The enclosed inspection report documents the inspection results, which were discussed on August 22, 2013, with you and other members of your staff.
The inspection was an examination of activities conducted under your license as they relate to the identification and resolution of problems, and compliance with the Commissions rules and regulations and with the conditions of your operating license. Within these areas, the inspection involved examination of selected procedures and representative records, observations of plant equipment and activities, and interviews with personnel.
Based on the inspection sample, the inspection team concluded that the implementation of the corrective action program and overall performance related to identifying, evaluating, and resolving problems at Shearon Harris Nuclear Power Plant Unit 1 was adequate. Licensee identified problems were entered into the corrective action program at a low threshold.
Problems were generally prioritized and evaluated commensurate with the safety significance of the problems. Corrective actions were generally implemented in a timely manner commensurate with their importance to safety and addressed the identified causes of problems.
Lessons learned from the industry operating experience were generally reviewed and applied when appropriate. Audits and self-assessments were effectively used to identify problems and appropriate actions.
No findings were identified during this inspection.

SUMMARY OF FINDINGS
IR 05000400/2013007: 08/05/2013 - 08/23/2013; Shearon Harris Nuclear Power Plant, Unit 1;
Biennial Inspection of Problem Identification and Resolution Program.
The inspection was conducted by two senior project engineers, a project engineer, a resident inspector, and a senior health physicist. No findings were identified. The NRCs program for overseeing the safe operation of commercial nuclear power reactors is described in NUREG-1649, Reactor Oversight Process, Revision 4.
Identification and Resolution of Problems The inspectors concluded that, in general, problems were properly identified, evaluated, prioritized, and corrected. The licensee was effective at identifying problems and entering them into the corrective action program (CAP) for resolution, as evidenced by the relatively few number of deficiencies identified by external organizations (including the NRC) that had not been previously identified by the licensee, during the review period. Generally, prioritization and evaluation of issues were adequate, formal root cause evaluations for significant problems were adequate, and corrective actions specified for problems were acceptable. Overall, corrective actions developed and implemented for issues were generally effective and implemented in a timely manner.
Operating experience usage was found to be generally acceptable and integrated into the licensees processes for performing and managing work, and plant operations. The inspectors determined that overall, audits and self-assessments were adequate in identifying deficiencies and areas for improvement in the CAP, and appropriate corrective actions were developed to address the issues identified.
Based on discussions and interviews conducted with plant employees from various departments, the inspectors determined that personnel at the site felt free to raise safety concerns to management and use the CAP to resolve those concerns.
REPORT DETAILS
OTHER ACTIVITIES
4OA2 Problem Identification and Resolution
a.
Assessment of the Corrective Action Program
- (1) Inspection Scope The inspectors reviewed the licensees corrective action program (CAP) procedures which described the administrative process for initiating and resolving problems primarily through the use of Nuclear Condition Reports (NCRs). To verify that problems were properly identified, appropriately characterized and entered into the CAP, the inspectors reviewed NCRs that were issued between July 2011 and July 2013, including a detailed review of selected NCRs associated with the following risk-significant systems: Reactor Coolant System (RCS) Power-Operated Relief Valves (PORVs), Residual Heat Removal (RHR) System, Component Cooling Water system, Emergency Diesel Generators, Instrument and Service Air system, AC & DC Power Systems, and Radiation Monitors.
Where possible, the inspectors independently verified that the corrective actions were implemented. The inspectors also reviewed selected common causes and generic concerns associated with root cause evaluations to determine if they had been appropriately addressed. To help ensure that samples were reviewed across all cornerstones of safety identified in the NRCs Reactor Oversight Process, the inspectors selected a representative number of NCRs that were identified and assigned to the major plant departments, including operations, maintenance, engineering, health physics, chemistry, and security. The inspectors reviewed selected NCRs, verified corrective actions were implemented, and attended meetings where NCRs were screened for significance to determine whether the licensee was identifying, accurately characterizing, and entering problems into the CAP at an appropriate threshold.
The inspectors conducted plant walkdowns of equipment to assess the material condition and to identify any deficiencies that had not been previously entered into the CAP. The inspectors reviewed NCRs, maintenance history, completed work orders for the systems, and reviewed associated system health reports. These reviews were performed to verify that problems were being properly identified, appropriately characterized, and entered into the CAP. Items reviewed generally covered a two-year period; however, in accordance with the inspection procedure, a five-year review was performed for selected systems for age-dependent issues.
Control room reviews were also performed to assess the Main Control Room deficiency list and to ascertain if deficiencies were entered into the CAP. The inspectors reviewed Operator Workarounds and Operator Burden screenings and verified compensatory measures were implemented for deficient equipment.
The inspectors conducted a detailed review of selected NCRs to assess the adequacy of the root-cause and apparent-cause evaluations of the problems identified. The inspectors reviewed these evaluations against the descriptions of the problem described in the NCRs and the guidance in licensee procedures CAP-NGGC-0205, Condition Evaluation and Corrective Action Process. The inspectors assessed if the licensee had adequately determined the causes of identified problems, and had adequately addressed operability, reportability, common cause, generic concerns, extent-of-condition, and extent-of-cause. The review also assessed if the licensee had appropriately identified and prioritized corrective actions to prevent recurrence for significant conditions adverse to quality.
The inspectors attended various plant meetings to observe management oversight functions of the corrective action process. These included NCR screening meetings and Performance Improvement Oversight Committee (PIOC) meetings.
Documents reviewed are listed in the Attachment.
- (2) Assessment Identification of Issues The inspectors determined that the licensee was generally 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 NCRs as described in licensee procedure CAP-NGGC-0200, Condition Identification and Screening Process, managements expectation that employees were encouraged to initiate NCRs for any reason, and the relatively few number of deficiencies identified by inspectors during plant walkdowns not already entered into the CAP. Trending was generally effective in monitoring equipment performance. Site management was actively involved in the CAP and focused appropriate attention on significant plant issues.
Prioritization and Evaluation of Issues Based on the review of NCRs sampled by the inspection team during the onsite period, the inspectors concluded that problems were generally prioritized and evaluated in accordance with the licensees CAP procedures as described in the NCR severity level determination guidance in CAP-NGGC-0200, Condition Identification and Screening Process. Each NCR was assigned a significance level at the CAP screening meeting, subsequently reviewed at the PIOC, and adequate consideration was given to system or component operability and associated plant risk.
The inspectors determined that station personnel had conducted root cause and apparent cause analyses in compliance with the licensees CAP procedures and assigned cause determinations were appropriate, considering the significance of the issues being evaluated. A variety of formal causal-analysis techniques were used depending on the type and complexity of the issue consistent with CAP-NGGC-0205.
Effectiveness of 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 and non-recurring. For significant conditions adverse to quality, the corrective actions directly addressed the cause and effectively prevented recurrence.
Effectiveness reviews for corrective actions to prevent recurrence were sufficient to ensure corrective actions were properly implemented and were effective.
- (3) Findings No findings were identified.
b.
Assessment of the Use of Operating Experience (OE)
- (1) Inspection Scope The inspectors examined licensee programs for reviewing industry operating experience, reviewed licensee procedure CAP-NGGC-0202, Operating Experience and Construction Experience Program, and reviewed the licensees operating experience database to assess the effectiveness of how external and internal operating experience data was handled at the plant. In addition, the inspectors selected operating experience documents (e.g., NRC generic communications, 10 CFR Part 21 reports, licensee event reports, vendor notifications, and plant internal operating experience items, etc.), which had been issued since July 2011 to verify whether the licensee had appropriately evaluated each notification for applicability to the Harris plant, and whether issues identified through these reviews were entered into the CAP. Procedure CAP-NGGC-0202, Operating Experience and Construction Experience Program," was reviewed to verify that the requirements delineated in the program were being implemented at the station. Documents reviewed are listed in the Attachment.
- (2) Assessment Based on a review of documentation related to the review of operating experience issues, the inspectors determined that the licensee was generally effective in screening operating experience for applicability to the plant. Industry OE was evaluated by the plant OE Coordinator and relevant information was then forwarded to the applicable department for further action or informational purposes. OE issues requiring action were entered into the CAP for tracking and closure. In addition, operating experience was included in all root cause evaluations in accordance with licensee procedure CAP-NGGC-205.
- (3) Findings No findings were identified.
c.
Assessment of Self-Assessments and Audits
- (1) Inspection Scope The inspectors reviewed audit reports and self-assessment reports, including those which focused on problem identification and resolution, to assess the thoroughness and self-criticism of the licensee's audits and self assessments, and to verify that problems identified through those activities were appropriately prioritized and entered into the CAP for resolution in accordance with licensee procedure CAP-NGGC-0201, Self-Assessment and Benchmarking Program.
- (2) Assessment The inspectors determined that the scopes of assessments and audits were adequate.
Self-assessments were generally detailed and critical, as evidenced by findings consistent with the inspectors independent review. The inspectors verified that NCRs were created to document all deficiencies resulting from the self-assessments, and verified that actions had been completed consistent with those recommendations.
Generally, the licensee performed evaluations that were technically accurate. Site trend reports were thorough and a low threshold was established for evaluation of potential trends, as evidenced by the NCRs reviewed that were initiated as a result of adverse trends.
- (3) Findings No findings were identified.
c.
Assessment of Safety-Conscious Work Environment
- (1) Inspection Scope The inspectors randomly interviewed several on-site workers regarding their knowledge of the CAP and their willingness to write NCRs or raise safety concerns. During technical discussions with members of the plant staff, the inspectors also conducted interviews to develop a general perspective of the safety-conscious work environment.
The interviews were also conducted to determine if any conditions existed that would cause employees to be reluctant to raise safety concerns. The inspectors reviewed the licensees Employee Concerns Program (ECP) and interviewed the ECP manager.
Additionally, the inspectors reviewed a sample of ECP issues to verify that concerns were properly reviewed and identified deficiencies were resolved and entered into the CAP when appropriate.
- (2) Assessment The inspectors determined that licensee management emphasized the need for all employees to identify and report problems using the appropriate methods established within the administrative programs, including the CAP and ECP. These methods were readily accessible to all employees. The inspectors determined that employees felt free to raise issues, and that management encouraged employees to place issues into the CAP for resolution.
The inspectors did not identify any reluctance on the part of the licensee staff to report safety concerns.
- (3) Findings No findings were identified.
4OA6 Meetings, Including Exit
On August 22, 2013, the inspectors presented the inspection results to Mr. E.
Kapopoulos and other members of the sites staff. The inspectors confirmed that all proprietary information examined during the inspection had been returned to the licensee.
