Enclosure AUDIT TRIP REPORT ENTERGY NUCLEAR OPERATIONS, INC., LICENSE RENEWAL APPLICATION FOR THE PILGRIM NUCLEAR POWER STATION, DATED JANUARY 25, 2006 I. Introduction During the week of June 6-9, 2006, Bill Rogers, Greg Galletti, and Steve Tingen of the Quality and Vendor Branches A & B, audited the Entergy Nuclear Operations, Inc. (the applicant) license renewal scoping and screening methodology developed to support the Pilgrim Nuclear Power Station (PNPS) license renewal application (LRA). The audit was performed at the applicants facility outside of Plymouth, Massachusetts. The focus of the staffs audit was on the applicants administrative controls governing implementation of the LRA scoping and screening methodology and review of the technical basis for selected scoping and screening results for various plant systems, structures, and components. The audit team also reviewed quality attributes for aging management programs, training for personnel that developed the LRA, and quality practices used by the applicant to develop the LRA.

II. Background Title 10 of the Code of Federal Regulations, Part 54 (10 CFR Part 54), "Requirements for Renewal of Operating Licenses for Nuclear Power Plants, Section 54.21, Contents of Application Technical Information, requires that each application for license renewal contain an integrated plant assessment (IPA). Furthermore, the IPA must list and identify those structures and components (SCs) that are subject to an aging management review (AMR) from the systems, structures, and components (SSCs) that are within the scope of license renewal.

10 CFR 54.4(a) identifies the plant SSCs within the scope of license renewal. SCs within the scope of license renewal are screened to determine if they are long-lived, passive equipment that is subject to an aging management review in accordance with 10 CFR 54.21(a)(1).

III. Scoping Methodology The scoping evaluations for the PNPS LRA were performed by the applicants license renewal project personnel and contractor personnel. The audit team conducted detailed discussions with the applicants license renewal project management personnel and reviewed documentation pertinent to the scoping process. The audit team assessed if the scoping methodology outlined in the LRA and implementation procedures was appropriately implemented and if the scoping results were consistent with current licensing basis requirements. The audit team also reviewed a sample of system scoping results for the following systems and structures: Reactor Core Isolation Cooling and Yard Structures (structural review).

In general, the team determined that the applicants overall approach to license renewal SSC scoping appeared to be adequate. However, the audit team identified several issues where additional information will be required to complete the LRA review. These issues are documented in a request for additional information and are briefly described below.

During the scoping and screening methodology audit, the NRC audit team questioned how non-accident design basis events, particularly design basis events that may not be described in the Updated Final Safety Analysis Report (UFSAR), were considered during scoping. The NRC audit team noted that limiting the review of design bases events to those described in the UFSAR accident analysis could result in omission of safety-related functions described in the current licensing basis. The audit team, therefore, requested the applicant to provide a list of the design basis events evaluated as part of the license renewal scoping process, and describe the methodology used to ensure that all design bases events (including conditions of normal operation, anticipated operational occurrences, design basis accidents, external events, and natural phenomena) were addressed during license renewal scoping.

Based on a review of the LRA, the applicants scoping and screening implementation procedures, and discussions with the applicant, the audit team determined that additional information is required with respect to certain aspects of the applicants evaluation of the 10 CFR 54.4(a)(2) criteria. The audit team requested that the applicant provide supplemental information regarding how the structural boundary, which includes the portion of the non-safety piping system outside the safety-related pressure boundary and relied upon to provide structural support for the pressure boundary, was developed. Additionally, the team requested the applicant to define equivalent anchors and indicate whether equivalent anchors were used to determine any plant system structural boundary.

IV.

Screening Methodology The audit team reviewed the methodology used by the applicant to determine if mechanical, structural, and electrical components within the scope of license renewal would be subject to further aging management review. The applicant provided the audit team with a detailed discussion of the processes used for each discipline and provided administrative documentation that described the screening methodology. The audit team also reviewed the screening results reports for the Reactor Core Isolation Cooling system and Yard Structures. The team noted that the applicants screening process was performed in accordance with its written requirements and was consistent with the guidance provided in NUREG-1800, Standard Review Plan for Review of License Renewal Applications for Nuclear Power Plants, Revision 1, (LR-SRP), and the Nuclear Energy Institute (NEI) 95-10, Industry Guidelines for Implementing the Requirements of 10 CFR Part 54 - The License Renewal Rule, Revision 6, (NEI 95-10). The audit team determined that the screening methodology was consistent with the requirements of the Rule for the identification of SSCs that meet the screening criteria of 10 CFR 54.21(a)(1).

V.

Aging Management Program Quality Assurance Attributes The NRC staff reviewed the applicants Aging Management Programs (AMPs) described in Appendix A, Updated Safety Analysis Report Supplement, and Appendix B, Aging Management Programs and Activities, of the LRA, and License Renewal Project Document (LRPD)-02, Aging Management Program Evaluation Report, Revision 1.

The purpose of this review was to ensure that the quality assurance attributes (corrective action, confirmation process, and administrative controls) were consistent with the staffs guidance described in NUREG-1800, Section A.2, Quality Assurance for Aging Management Programs (Branch Technical Position IQMB-1).

Based on the NRC staffs evaluation, the descriptions of the AMPs and their associated quality attributes provided in Appendix A, Section A.2.1, and Appendix B, Section B.0.3, of the LRA are consistent with the staffs position regarding quality assurance for aging management. However, the description of the corrective action attribute in Section 2.0 of LRPD-02 did not credit the 10 CFR Part 50, Appendix B, quality assurance program.

Therefore, the NRC staff requested that the applicant clarify that the same corrective action program will be applied to all AMPs and that this program meets the requirements of 10 CFR Part 50, Appendix B.

VI. Quality Assurance Controls Applied to LRA Development The NRC audit team reviewed the quality controls used by the applicant to ensure that scoping and screening methodologies utilized in the LRA were adequately implemented.

Although the applicant did not develop the LRA under a 10 CFR 50, Appendix B, QA program, the applicant utilized the following quality assurance (QA) processes during the LRA development:

Implementation of the scoping and screening methodology was governed by written procedures.

The applicant reviewed previous LRA NRC requests for additional information to ensure that applicable issues were addressed in the LRA.

The LRA was reviewed by the Off-Site and On-Site Safety Review Committees prior to submittal to the NRC.

The applicant performed an industry peer review of the LRA.

The applicants QA organization performed an independent review of the LRA. The purpose of this review was to ensure that the technical information used to develop the LRA was updated and approved in accordance with the stations QA program, and that industry peer and Off-Site and On-Site Safety Review Committee issues were resolved and associated corrective actions implemented.

The audit team concluded that these quality assurance activities, which exceeded current regulatory requirements, provided additional assurance that LRA development activities were performed consistently with the LRA descriptions.

VII.

Training for License Renewal Project Personnel The audit team reviewed the applicants training process to ensure the guidelines and methodology for the scoping and screening activities would be performed in a consistent and appropriate manner. The NRC audit team reviewed the applicants training process to ensure the guidelines and methodology for the scoping and screening activities were performed in a consistent and appropriate manner.

The License Renewal Project Guidelines (LRPGs) provided the guidance and requirements for the training of the license renewal (LR) project and site personnel. The training consisted of a combination of reading and attending training sessions. The attachment specified the level of training which was required for the various groups participating in the development of the LRA and began with initial training, documented on a qualification card. The training was required for both the LR project personnel who prepared the application and for the site personnel who reviewed the application. In addition, LR refresher training was provided for the LR project and site personnel participating in the review. Refresher training included information on the LR process and information specific to the site. LR project and site personnel were required to review applicable LR regulations, NEI 95-10 and associated procedures. The applicant developed periodic production meetings in which the LR project personnel shared their knowledge and experience of a given subject with each other.

The NRC audit team reviewed completed qualification and training records of several of the applicant's LR project personnel and also reviewed completed check lists. The audit team found these records adequately documented the required training for the LR project personnel. Additionally, based on discussions with the applicant's LR project personnel during the audit, the audit team verified that the applicant's LR project personnel were knowledgeable on the LR process requirements and the specific technical issues within their areas of responsibility.

On the basis of discussions with the applicants license renewal project personnel responsible for the scoping and screening process, and a review of selected design documentation in support of the process, the audit team concluded that the applicants LR project personnel understood the requirements of and adequately implemented the scoping and screening methodology established in the applicants renewal application.

The audit team did not identify any concerns regarding the training of the applicants LR project or site personnel.

VIII.

Exit Meeting A public exit meeting was held with the applicant on July 26, 2006, to discuss the results of the scoping and screening methodology audit. The audit team identified preliminary areas where additional information would be required to support completion of the staffs LRA review. Requests for additional information related to the applicants scoping and screening methodology were forwarded to the applicant on July 25, 2006 (ADAMS Accession No.ML062070240).
