Type Issue Number Title Report Section Status LER 05000443/2020-001-00 LER 2020-001-00 for Seabrook Station, Manual Reactor Trips due to Control Rod Bank Unexpectedly Inserting 71153 Closed
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)
- (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 also conducted a five-year review of the emergency feedwater system.
- 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.
71153 - Followup of Events and Notices of Enforcement Discretion Event Report (IP Section 03.02)
The inspectors evaluated the following licensee event reports (LERs):
- (1) LER 05000443/2020-001-00, Manual Reactor Trips due to Control Rod Bank Unexpectedly Inserting (ADAMS Accession No. ML20209A542). Inspectors reviewed the root cause evaluation and associated corrective actions for the two events reported. Inspectors determined that the corrective actions taken or in progress were appropriate and commensurate with their safety significance. The inspectors determined that the cause of the condition described in the LER was not reasonably within the licensees ability to foresee and correct and therefore was not reasonably preventable. No performance deficiency nor violation of NRC requirements was identified.
INSPECTION RESULTS
Assessment 71152B Corrective Action Program
Identification: The inspectors determined that NextEra identified issues and entered them into the corrective action program at a low threshold. During plant walk downs, there was evidence of continued focus to improve the look and condition of the plant. The inspectors identified a few deficiencies not previously identified and captured in NextEras corrective action program. NextEra promptly entered each issue into their corrective action program and took actions to evaluate and address. All issues were determined to be of minor significance.
Prioritization and Evaluation: Based on the samples reviewed, the inspectors determined that NextEra appropriately prioritized and evaluated issues commensurate with the safety significance of the identified problem. NextEra appropriately screened condition reports (ARs) for operability and reportability, categorized ARs by significance, and assigned actions to the appropriate department for evaluation and resolution.
Correcting Problems: The inspectors determined that the overall corrective action program performance related to resolving problems was effective. In most cases, NextEra implemented corrective actions to resolve problems in a timely manner. However, the inspectors noted some challenges with the tracking and the timely close-out of corrective actions (CAs) for conditions adverse to quality (CAQ). See below for details concerning this observation.
Assessment 71152B Operating Experience, Self-Assessments and Audits
Use of Operating Experience: The team determined that NextEra appropriately evaluated industry operating experience for its relevance to the facility. NextEra appropriately incorporated both internal and external operating into plant procedures and processes, as well as lessons learned for training and pre-job briefs.
Self-Assessments and Audits: The team reviewed a sample of self-assessments and audits to assess whether the licensee was identifying and addressing performance trends. The team concluded that NextEra had an effective self-assessment and audit process.
Assessment 71152B Safety Conscious Work Environment
The team interviewed a total of 38 individuals: 13 in focus groups and 25 in one-on-one interviews. The purpose of these interviews was
- (1) to evaluate the willingness of the licensee staff to raise nuclear safety issues,
- (2) to evaluate the perceived effectiveness of the corrective action program at resolving identified problems, and
- (3) to evaluate the licensee's safety-conscience work environment. The personnel interviewed were randomly selected by the inspectors from the Operations, Engineering, Maintenance, Security, Information Technology, Emergency Preparedness, and Radiation Protection work groups. To supplement these discussions, the team interviewed the Employee Concerns Program (ECP)
Coordinator to assess their perception of the site employees' willingness to raise nuclear safety concerns. The team also reviewed the ECP case log and selected case files.
All individuals interviewed indicated that they would raise safety concerns. All individuals felt that their management was receptive to receiving safety concerns and generally addressed them promptly, commensurate with the significance of the concern. Most interviewees indicated they were adequately trained and proficient on initiating notifications. All interviewees were aware of the licensee's ECP, stated they would use the program if necessary, and expressed confidence that their confidentiality would be maintained if they brought issues to the ECP. When asked whether there have been any instances where individuals experienced retaliation or other negative reaction for raising safety concerns, all individuals interviewed stated that they had neither experienced nor heard of an instance of retaliation at the site. The team determined that the processes in place to mitigate potential safety culture issues were adequately implemented.
Observation: Tracking of Corrective Actions 71152B The inspectors noted an area of vulnerability to ensuring adequate and timely close-out of corrective actions once the associated ARs were closed to work order (WO), work request (WR), or the procedure change request (PCR) processes. PI-AA-01, Corrective Action Program and Condition Reporting, provides implementation guidance for NextEra that directs corrective actions to be completed in accordance with due dates that are assigned commensurate with their significance and assigned priority and discusses the critical attributes for a successful corrective action program, specifically: completion of activities prior to due dates, effective resolution of problems, maintenance of low backlogs of open evaluations and actions, effective monitoring and management oversite, and meaningful feedback to condition report initiators.
The inspectors determined that these critical attributes have the potential to be challenged because PI-AA-104-1000, Condition Reporting, allows CAs associated with conditions adverse to quality to be closed to an approved WO/WR/PCR, provided that the CA is not associated with a significance level 1 AR, not an inoperable, nonfunctional, operable/function but degraded, or operable/functional but non-conforming, as long as a cross-reference is made to the AR, and the WO, WR, and PCR is assigned the correct category per PI-AA-104-1000. (4.3.5.F).
The inspectors identified several examples of untimely CA for CAQ after the associated condition report was closed to a WO, WR, or PCR processes. The most significant example identified by the inspectors involved condition report AR2283006 which documented boric acid in contact with the bonnet studs on the inlet isolation valve in the charging system.
NextEra previously completed an evaluation of the condition and concluded that continued operation was acceptable until refueling outage OR20 and the bonnet gasket should be replaced at that time. AR2285040 was written to identify this condition and was closed to work request WR94184073. WR94184073 was subsequently converted to work order WO40626697 to be worked during refueling outage OR20 in April 2020. WO40626697 was later deferred from OR20 to OR21 without replacing the bonnet gasket or completing a corrective action program evaluation, as required by the corrective action. Following the inspectors questions, NextEra updated the evaluation to support operation until OR21 when the bonnet gasket will be replaced (AR02374481). The inspectors noted that in preparation for the NRC problem identification and resolution inspection, NextEra completed a self-assessment (AR02369293) that identified a similar observation to the inspectors in that CAs closed to other products (i.e. PCRs, WOs) were not always being tracked to completion which has led to untimely corrective action completion in some cases. The self-assessment also noted that this was similar to a gap identified in a 2018 self-assessment (AR02369984).
The inspectors also identified several examples in which WR/WO associated with CAs for CAQ were assigned an incorrect priority. Specifically,
- (1) AR2359680 (CAQ CA) was closed to Priority 3 WR94027409/ Priority 3 WO40097004;
- (2) AR2344818 (CAQ CA) was closed to Priority 3 WO40438884; and
- (3) AR2346954 (CAQ CA) was closed to Priority 3 WO40630759. Per procedure PI-AA-104-1000, the condition reports should have been closed to a Priority 1 or 2 WO. This would help ensure timely corrective action.
Inspectors determined that none of the examples above would have screened as a more than minor performance deficiency.
