.1 Post-Approval Site Inspection for License Renewal (Phase III) - Inspection Procedure
71003
a. Inspection Scope
The inspectors reviewed the licensees extent-of-condition and extent-of-cause investigations, and the corrective actions that resulted from the open condition reports (CRs) initiated during the previous Post-Approval Site Inspection for License Renewal (Inspection Report (IR) 05000255/2011008). Particular emphasis was placed on the five findings with three associated Non-Cited Violations (NCVs). The inspectors also reviewed the results and actions from self-assessment activities in regards to aging management. The inspectors reviewed work activities, associated with aging management programs, completed between March 2011 and this inspection; the licensees use of operating experience (OE) related to aging management; and the integration of aging management program (AMP) into the licensees routine programs, practices, and work activities, particularly in the corrective action program (CAP).
Due to questions on the licensees fatigue monitoring program (FMP) requirements and activities from IR 05000255/2012007, completed on February 17, 2012, the inspectors continued reviewing the FMP during this inspection.
b. Assessment
- (1) Condition Reports from IR 2011008 Findings The inspectors conducted interviews and reviewed CAP actions for each finding, and associated NCV (if applicable), including supporting documents and completed surveillance records or work items for the following:
- (a) Failure to Assure Adequate Resolution for Remote Visual Examinations (NCV 05000255/2011008-01);
- (b) Test Results for Diesel Fuel Oil Tanks Not Evaluated (NCV 05000255/2011008-02);
- (c) Tank T-10A Not Age Managed for Effect of Identified Water (NCV 05000255/2011008-03);
- (d) Flow Accelerated Corrosion Program Acceptance Limits Not in Accordance with Design Standard (FIN 05000255/2011008-04); and
- (e) Failure to Implement Adequate Oil Sampling and Analysis Aging Management Program (FIN 05000255/2011008-05).
Observations The inspectors found the assessments and corrective actions for the findings to be adequate. The licensee had taken reasonable corrective actions to ensure meeting and continuing to integrate the AMP commitments into the existing programs. Specific measures had been taken to address each of the deficiencies associated with the individual findings.
Findings No findings of significance were identified.
- (2) Other CRs Initiated as a Result of IR 2011008 The inspectors reviewed the resolution of CRs initiated as a result of the previous inspection. The inspectors reviewed the completed evaluations, and the corrective actions for proper prioritization, (root cause, apparent cause, and common cause) and probable effectiveness, especially as to addressing aging issues.
Findings No findings of significance were identified.
- (3) Self-Assessments The inspectors assessed the licensee staffs ability to identify and enter issues into the CA program, prioritize and evaluate issues, and implement effective corrective actions through efforts from self-assessments. Specifically, the inspectors reviewed Snapshot Assessment, LO-PLPLO-2010-00132 CA-1, Palisades NRC IP71003 Phase III Inspection Readiness, dated September 11, 2011, for aging management aspects, as well as the overall self-assessment effort.
Observations The inspectors found the snapshot assessment to be thorough and insightful. The licensee identified that previous corrective actions (CAs) had not been effective and had initiated new CRs to address the deficiencies. The new CRs were detailed and addressed the aging management aspects appropriately.
Findings No findings of significance were identified.
- (4) AMP Work Activities Completed from March 2011 to Present The inspectors reviewed the completed individual work items associated with AMPs, particularly for ties to the AMPs and for the integration of the AMP requirements into the routine planning and work order evolutions. The items reviewed included five boric acid evaluation/screenings; emergency diesel generator (EDG) jacket water and lube oil cooler inspection (and the associated CRs); a Maintenance Rule (a)(1) plan for roof structures; 2011 3rd quarter oil sampling and analysis reports; Fatigue Monitoring Program Summary Reports and Summary Cycle Reports for Cycles 19, 20, and 21; two fuel oil monitoring and maintenance work orders; and a utility water storage tank, T-91, internal inspection work order.
Observations The inspectors found the work activities to be thorough and complete. However, it was not always clear that the activity was tied to an aging management commitment. For example, the lube oil sampling and analysis program was driven solely through the licensees pre-existing preplanned preventive maintenance items (PMs). There was no clear identification that the PMs were fulfilling aging management commitments and no clear requirements to review AMP commitments before changing or eliminating the PMs.
Additionally, the boric acid evaluations had no discernible connection to the associated AMPs. Based on the observations in this area, the inspectors had a concern for how the licensee ensured that aging management activities would not be delayed, changed, or cancelled without the program owner and/or management involvement. This concern is addressed in Section 4OA5.1.b(6) below.
Findings No findings of significance were identified.
- (5) Use of Operating Experience in Aging Management The inspectors reviewed the licensees implementation of the facilitys operating experience (OE) program. Specifically, the inspectors reviewed implementing OE program procedures and completed evaluations of aging management OE issues and events, and interviewed individuals with respect to the use of OE with respect to aging management. The inspectors review was to determine whether the licensee was effectively integrating aging management OE into the performance of daily activities, whether evaluations of issues were proper, whether the licensees program was sufficient to prevent future occurrences of previous industry events, and whether the licensee effectively used the information in developing departmental assessments and facility audits. The inspectors looked particularly at the licensees handling of of the following:
- Information Notice (IN) 2011-15, Steel Containment Degradation and Associated License Renewal Aging Management Issues;
- IN 2011-20, Concrete Degradation Concrete Degradation By Alkali-Silica Reaction;
- Regulatory Issue Summary (RIS) 2011-05, Information On Revision 2 To The Generic Aging Lessons Learned Report For License Renewal Of Nuclear Power Plants;
- RIS 2011-07, License Renewal Submittal Information for Pressurized Water Reactor Internals Aging Management; and
- RIS 2011-14, Metal Fatigue Analysis Performed By Computer Software.
Observations With one exception, the inspectors determined that the licensee was adequately reviewing and incorporating aging management OE into the plants processes, procedures, and work activities. However, the site had not evaluated RIS 2011-05.
The inspectors noted that RIS 2011-005 was screened by the fleet OE team on July 13, 2011, and was distributed to each Entergy site. An OE Written Action (NRC-RIS-2011-05-A2-IPC-0001) was initiated and work task LO-WTIPC-2011-00029 CA 116 was assigned to corporate licensing to review the RIS. The work task was subsequently closed to a headquarters condition report (CR-HQN-2011-01045). The response CA 6 to CR-HQN-2011-01045 assigned reviews of RIS 2011-005, in the Entergy OE process, to fleet license renewal personnel. At the time of this inspection, the evaluation of RIS 2011-05 had not been completed. The licensee initiated CR-HQN-2012-00333 to document the delay in the OE evaluation of RIS 2011-005.
Findings No findings of significance were identified.
- (6) Integration of Aging Management Program Commitments into Routine Processes Due to concerns developed during the inspection (Item
- (4) above), the inspectors reviewed how the licensee incorporated the aging management commitments into the everyday activities; particularly as to how the review for aging concerns would become a standard review question and assimilated into the licensees review process.
Observations The inspectors reviewed the AMP commitments and the procedures governing how aging management issues were controlled to ensure no items could be delayed, cancelled, or deferred without the program owners, supervisors, or managers knowledge and concurrence. The inspectors also interviewed the AMP single point of contact and several program owners. The inspectors did not observe a clear, readily discernible tie between the implementing work items and aging management commitments. However, carefully reviewing all of the governing procedures and documents revealed that the tie to aging management was established and that AMP commitments had to be reviewed before any of the items could be revised or discarded.
During the review, the inspectors noted that a code had been established in the CAP to note aging issues on any CR reviewed by the condition review group(CRG); however, no specific item in the review process had been established to examine every CR for any possible lessons learned or impact on aging management. In response to this question, the licensee added a specific item to the CRG package checklist to ensure that CRs involving aging management are trended correctly.
Findings No findings of significance were identified.
- (7) Fatigue Monitoring Program The Fatigue Monitoring Program (FMP) ensures that limits on the fatigue usage are not exceeded by monitoring and tracking selected cyclic transients. The program provides cycle counting activities for confirming analytically derived cumulative usage values.
As documented in the Palisades Nuclear Plant - Problem Identification and Resolution Inspection Report 05000255/2012007, the inspectors were concerned with the timeliness of actions associated with approving the use of a software program in the Fatigue Monitoring program. The inspectors also questioned the adequacy of the program for ensuring thermal cycles tracking. Inspection of these items continued during this current inspection.
Observations The inspectors consulted with the NRR staff to determine the specific commitments for the Palisades FMP. Subsequently, the inspectors interviewed personnel, reviewed the pressurizer design specification, reviewed procedures, and reviewed PLP-RPT-12-00023, Fatigue Monitoring Program Summary Report, Revision 0, and determined that the licensee was meeting the AMP commitment for the fatigue monitoring program.
Findings No findings of significance were identified.
