-3-DETAILS 1 INSERVICE INSPECTION - OBSERVATION (73753)

The objectives of this inspection were to ascertain whether inservice examinations, repair, and replacement of Class 1, 2, and 3 pressure retaining components are performed in accordance with the Technical Specifications, the applicable American Society of Mechanical Engineers (ASME) Boiler and Pressure Vessel Code, correspondence between NRR and the licensee concerning relief requests, and requirements imposed by NRC/ industry initiative .1 Discussion The inspectors observed the inservice inspection activities associated with the nondestructive examination of four pipe welds in the safety injection system and a pipe support for the reactor coolant system. The inspectors were informed that no ASME Code Section XI repair or replacement activities had-been scheduled for the outag The inspectors observed liquid penetrant and/or ultrasonic examinations performed on the four pipe welds. Liquid penetrant examinations were performed on three welds that were identified as TBX-1-4103-1. TBX-2-2566-35, and TBX-2-2566-36, using Procedure TX-ISI-11. " Liquid Penetrant Examination,"

Revision 3, and an approved procedure field change request, FC-001. The ultrasonic examinations performed included the calibration and examination of Welds TBX-1-4103-1 and TBX-2-2565-36, using Procedure TX-ISI-207, " Ultrasonic Examination of Similar and Dissimilar Metal Welds in Austenitic Stainless Steel Piping Systems,"' Revision 1. The inspectors also observed the visual inspection, VT-3 of Pipe Support TBX-1-4109-HS, using Procedure TX-ISI-8,

" Visual Examination," Revision The inspectors verified that the examinations were performed using approved procedures and qualified personnel certified as Level 11 examiners for the nondestructive examination method used. For the liquid penetrant examinations, the inspectors also verified that procedure limitations were met for surface temperature and penetrant material contaminants. For that portion of the ultrasonic examination observed by the inspectors, the ultrasonic-system was calibrated, the temperature of the calibration block and component was measured, the distance amplitude curves were established, and the examination covered the required volume. The examinations were observed to be performed in full accordance with the requirements of the nondestructive examination procedures and the 1986 edition of Section XI of the ASME Cod The inspectors also reviewed the Comanche Peak Steam Electric Station 10-Year Inservice Inspection Plan, Revision 1 and Interim Change Request No. ISI-Rl-001, and verified that examinations were-accom)11shed as scheduled for the current inspection perio During this review, tie inspectors noted that the issuance of the inservice inspection plan and changes thereto was

" Inservice Inspection Program," Revision In reviewing the approval status of the inservice inspection plan for the first interval, which covers the period from February 8, 1990, to February 8, 2000, the inspectors determined that Revision 0 of the plan was approved by an NRR Safety Evaluation dated October 1,1992. The licensee issued Revision 1 to the plan on August 25, 1992, which was submitted to NRR on September 14, 199 .2 Conclusions The inservice inspection program was well documented and effectively implemented. Performance of nondestructive examinations were judged to be goo FEEDBACK OF OPERATIONAL EXPERIENCE INFORMATION (90700)

The purpose of this inspection was to determine the effectiveness of the licensee's program to assess and disseminate operational experience information pertinent to plant safety, which originated outside the organizatio .1 Proaram Verification The plant analysis group is responsible for the program, which is controlled and described in Nuclear Overview Department Procedure NQA 2.30, " Industry dated August 20, Operating Experience 1992, through Document Report Change Review Program,"

Notice (DCN) Revision 01 dated Octo 1,ber 30, 199 This procedure provided the specific details regarding the receipt, prioritization, tracking, evaluating, and closure of industry operating experience reports (10ERs), such as information notices received from the NRC, and the various categories of 10ERs received from the institute of Nuclear Power-Operations (INP0). The methodology specified for performing evaluations, making recommendations, obtaining technical review and approval, and verifying that recommended actions have been completed, was well planne The inspectors noted a minor procedural weakness in that it did not provide an escalation policy for those instances where requested responses from other organizations were overdue. A management escalation policy would preclude potential neglect and facilitate timely reviews of received operating experience information. This did not appear to be a problem at present,-in that there were currently six 10ERs overdue, with the oldest being 3-months late. The inspectors * review of the 10ERs determined that there was no urgency associated with any of the si Revision 1 to Procedure NQA 2.30 was considered a major revision with a number of program enhancements, including (1) the establishment of a review of the effectiveness of the program's implementation and (2) a review of recurring significant event reports with a concurrent evaluation of the effectiveness of

The procedure further provided that the effectiveness review could be limited to the 75 SOER recommendations categorized by INP0 in their document, INPO 91-007, as being

"of such a nature or importance that they should be retained and reviewed on an on-going basis." The inspectors were informed that ISEG had performed a Unit 2 completions assessment, which included a section that addressed a review of the 75 SOER recommendations, with 47 receiving a detailed revie These efforts were documented in ISEG Assessment Report No. IAR 92-09, dated September 25, 1992, which was reviewed by the inspectoe Station Administration Manual Procedure STA-509, " Commitment Tracking System,"

Revision 6 dated June 1,1992, established the guidelines and general format for the commitment tracking system (CTS), which was utilized to ensure that all commitments, whether regulatory or internal, are satisfied and maintaine The use of the CTS for 10ERs, such as NRC information notices and certain categories of INP0 reports, was part of a major enhancement to the process when Revision 1 to Procedure NQA 2.30 was issue .2 Proaram Implementation Procedure NQA 2.30 referenced Section 1.C.5 in NRC Document HUREG-0737,

" Clarification of THI Action Plan Requirements."Section I.C.5, " Procedures for feedback Of Operating Experience To Plant Staff." required each licensee to establish procedures pertaining to specific elements of an operating experience feedback program. One element required that periodic internal audits be performed to assure that the operating experience feedback program functions effectively at all levels. The inspectors requested information to support the licensee's accomplishment of internal audits in this are Operations Quality Assurance Audit Report QAA-91-104, "Nonconformance and Corrective Action Program," which was performed during January 28 through February 7, 1991, was provided to the inspectors. The inspectors review of the report revealed that it was an assessment of the corrective action process in terms of plant incident evaluations, root cause analysis, industry operating experience reviews, and in-house operating and trending data. The inspectors considered the audit to be an in-depth assessment of the progra The audit's conclusion determined that the program was satisfactory and was being implemented as required. Three observations were identified in the areas of tracking, assuring timely completion of recommended actions, and utilization of lessons learned. The inspectors noted that procedure revisions have addressed these concern Review of audit schedules and frequencies showed that the industry operating experience review program is on a biennial audit frequency and is currently scheduled for the first quarter of 199 The inspectors reviewed the "10ER Log Sheet" in order to determine the status-of 10ERs and to make a selection of both open and closed reports to evaluate program implementation (see Attachment 2). A total of eight closed reports, including five NRC information notices, two INP0 significant event

reports (SERs), and ono )otential 10 CFR Part 21 report, were selected and reviewed in terms of tecinical assessments, responses from cognizant individuals and grou)s, and establishment of internal commitments and their incorporation into tie CTS. The inspectors also verified that the committed actions had been implemented by review of documentation associated with those actions (e.g., preventive maintenance tasks, procedural revisions, training

. The inspectors also selected lesson plans, that seven reports andwere training shownattendance to be open, sheets)luding inc one NRC information notice, one INP0 operating plant experience report, one INP0 SER, and four INP0 SOERs. The purpose for selecting open reports was to verify that they were being actively tracked and that actions / evaluations were in-process. The inspectors also noted that the four SOERs had been previously closed, but recently reopened with respect to Unit 2. Several review efforts had been undertaken, including ISEG's assessment (IAR 92-09) and plant analysis'

September / October 1992 10ER Review, to assess 10ER completion status and potential impact on Unit These reviews determined that certain recommendations contained in eight SOERs had been closed based on actions taken with respect to Unit 1, but consideration had not been given towards Unit I and 2 differences. Therefore, those specific recommendations were reopened and are awaiting actions such as development of preventive maintenance procedures, test procedures, completion of baseline data, and training activitie These items, considered highly visible by management, were 5eing tracked by plant analysis as part of their normal functio Procedure HQA 2.30 required the issuance of a monthly report, "Open 10ER Recommendations," to senior station management in which the status of all open 10ER recommendations were to be presented. The inspectors reviewed the monthly reports for July, August, and September 1992, and found them to be consistent and accurat The inspectors also reviewed the background and technical qualifications of the plant analysis personnel responsible for performing assessms_ts and <

evaluations of incoming 10ERs and determined that all of the personnel were well qualifie The inspectors noted a proactive posture with respect to the 10ER progra One example had to do with a review, by plant analysis, of 10ERs applicable'to refueling outages and the compilation of " lessons learned" into a document which became part of the refueling manual being used for the current Unit I refueling outage (IRF02).

2.3 Conclusions With the exception of the minor procedural weakness noted in paragraph 2.1, the inspectors considered the 10ER program to be well defined and to be effectively implemented. As previously noted, the program recently underwent a major revision, which included a number of program enhancements -

The corrective actions included the re-examination of the weld during the second Unit I refueling outage and the review of all examination data sheets performed during Unit I refueling outage by a TV Electric Level 111 inspector to ensure all incomplete  :

examinations are documented on limitation sheets. The inspectors witnessed the satisfactory ultrasonic examination of the weld on November 4,1992, in addition, the inspectors reviewed the corrective actions taken to preclude recurrence, which included an audit of the inservice ins)ection and testing programs and two surveillance activities documented by tie independent safety engineering group. The audit and surveillance activities were documented in TV Electric Operations QA Audit Report QAA-92-123 and Independent Safety Engineering Group Field Note Sheets ISEG-FN-267 and 270. The corrective actions were satisfactorily completed by the date specified in the response to the violatio FOLLOWUP (92701)

This revision established the responsibilities and requirements for tracking internal commitments resulting from operating experience information in the commitment tracking syste The inspectors selected 15 10ERs - 8 closed and 7 open - (see Attachment 2)

and verified that the internal commitments initiated as a result of the 10ERs had been entered into the commitment tracking system and had been, or were being, tracked. The inspectors also verified that-the actions required by closed internal commitments had been implemented. Based on'the-results of the inspectors' review, it appears that the licensee had implemented the requirements established by Revision 1 to Procedure NQA 2.3 _- - __
