1 Audit and Review Plan for Plant Aging Management Reviews and Programs 1.
INTRODUCTION By letter dated October 4, 2006, Wolf Creek Nuclear Operating Corporation (WCNOC) submitted to the U.S. Nuclear Regulatory Commission (NRC) its application for renewal of Operating License No.NPF-42 for the Wolf Creek Generating Station (WCGS). The applicant requested renewal of the operating license for an additional 20 years beyond the 40-year current license term.
In support of the staff's safety review of the license renewal application (LRA) for WCGS, the Division of License Renewal (DLR), Branch C (RLRC), will lead a project team that will audit and review selected aging management reviews (AMRs) and associated aging management programs (AMPs), and time-limited aging analyses (TLAAs) developed by the applicant to support its LRA for WCGS. The project team will include NRC staff and engineers provided by Advanced Technologies and Laboratories International, Inc. (ATL), RLRCs technical assistance contractor. Appendix A, "Project Team Membership," lists the project team members. This document is the RLRC plan for auditing and reviewing plant aging management reviews and aging management programs for WCGS.
The project team will audit and review its assigned AMPs, AMRs, and TLAAs against the requirements of Title 10 of the Code of Federal Regulations, Part 54 (10 CFR Part 54),
"Requirements for Renewal of Operating Licenses for Nuclear Power Plants;" the guidance provided in NUREG-1800, Revision 1, "Standard Review Plan for Review of License Renewal Application for Nuclear Power Plants" (SRP-LR), dated September 2005; the guidance provided in NUREG-1801, Revision 1, "Generic Aging Lessons Learned (GALL) Report," dated September 2005; and this plan. For the scope of work defined in this audit plan, the project team will verify that the applicant's aging management activities and programs will adequately manage the effects of aging on structures and components, so that their intended functions will be maintained consistent with the WCGS current licensing basis (CLB) for the period of extended operation.
The project team will perform its work at NRC Headquarters, Rockville, Maryland; at ATL's offices in Germantown, Maryland; and at the WCGS site near Burlington, Kansas. The project team will perform its work in accordance with the schedule shown in Appendix B, "Schedule."
This plan includes the following information:
Introduction and Background. Summary of the license renewal requirements, as stated in the Code of Federal Regulations, and a summary of the documents that the project team will use to conduct the audit and review process described in this plan.

BACKGROUND In 10 CFR 54.4, the scope of license renewal is defined as those structures, systems, and components (SSCs) (1) that are safety-related, (2) whose failure could affect safety-related functions, and (3) that are relied on to demonstrate compliance with the NRC's regulations for fire protection, environmental qualification, pressurized thermal shock, anticipated transients without scram, and station blackout.
An applicant for a renewed license must review all SSCs within the scope of license renewal to identify those structures and components (SCs) subject to an AMR. SCs subject to an AMR are those that perform an intended function without moving parts or without a change in configuration or properties (passive), and that are not subject to replacement based on qualified life or specified time period (long-lived). Pursuant to 10 CFR 54.21(a)(3), an applicant for a renewed license must demonstrate that the effects of aging will be managed in such a way that the intended function(s) of those SCs will be maintained, consistent with the CLB, for the period of extended operation. 10 CFR 54.21(d) requires that the applicant submit a supplement to the final safety analysis report (FSAR) that contains a summary description of the programs and activities that it credited to manage the effects of aging during the extended period of operation.
Wolf Creek Generating Station AMP and AMR Audit and Review Plan 3
The SRP-LR provides staff guidance for reviewing applications for license renewal. The GALL Report is a technical basis document. It summarizes staff-approved AMPs for the aging management of a large number of SCs that are subject to an AMR. It also summarizes the aging management evaluations, programs, and activities acceptable to the NRC staff for managing aging of most of the SCs used in commercial nuclear power plants, and serves as a reference for both the applicant and staff reviewers to quickly identify those AMPs and activities that the staff has determined will provide adequate aging management during the extended period of operation. If an applicant commits to implementing these staff-approved AMPs, the time, effort, and resources needed to review an applicant's LRA will be greatly reduced, thereby improving the efficiency and effectiveness of the license renewal review process. The GALL Report identifies (1) systems, structures, and components, (2) component materials, (3) the environments to which the components are exposed, (4) the aging effects associated with the materials & environments, (5) the AMPs that are credited to manage the aging effects, and (6) recommendations for further applicant evaluations of aging effects and their management for certain component types.
The GALL Report is treated in the same manner as an approved topical report that is generically applicable. An applicant may reference the GALL Report in its LRA to demonstrate that its programs correspond to those that the staff reviewed and approved in the GALL Report. If the material presented in the LRA is consistent with the GALL Report and is applicable to the applicant's facility, the staff will accept the applicant's reference to the GALL Report. In making this determination, the staff considers whether the applicant has identified specific programs described and evaluated in the GALL Report but does not conduct a re-review of the substance of the matters described in the GALL Report. Rather, the staff confirms that the applicant verified that the approvals set forth in the GALL Report apply to its programs.
If an applicant takes credit for a GALL AMP, it is incumbent on the applicant to ensure that the plant AMP contains all the program elements of the referenced GALL AMP. In addition, the conditions at the plant must be bounded by the conditions for which the GALL AMP was evaluated. The applicant must certify in its LRA that it completed the verifications and that they are documented onsite in an auditable form.
The SRP-LR also provides staff guidance for reviewing TLAAs. Pursuant to 10 CFR 54.21(c)(1),
a license renewal application is required to provide a list of TLAAs, as defined in 10 CFR 54.3. In addition, the applicant must provide a list of plant-specific exemptions granted under 10 CFR 50.12 that are based on TLAAs. The number and type of TLAAs vary depending on the plant-specific CLB.
All six criteria set forth in 10 CFR 54.3 must be satisfied to conclude that a calculation or analysis is a TLAA. Pursuant to 10 CFR 54.3, TLAAs are those licensee calculations and analyses that:
- 1.
Involve systems, structures, and components within the scope of license renewal, as delineated in 10 CFR 54.4(a).
2.
Consider the effects of aging.
Wolf Creek Generating Station AMP and AMR Audit and Review Plan 4
3.
Involve time-limited assumptions defined by the current operating term, for example, 40 years.
4.
Were determined to be relevant by the licenses in making a safety determination.
5.
Involve conclusions or provide the basis for conclusions related to the capability of the system, structure, or component to perform its intended function(s), as delineated in 10 CFR 54.4(b).
6.
Are contained or incorporated by reference in the CLB.
Finally, the applicant must demonstrate that the TLAAs remain valid for the period of extended operation; the TLAAs have been projected to the end of the period of extended operation; or the effects of aging on the intended function(s) will be adequately managed for the period of extended operation. The staff performs a technical review as well as reviews the area relating to the identification of TLAAs. The staff also confirms that the applicant did not omit any TLAAs, as defined in 10 CFR 54.3.
3.
OBJECTIVES The overall objective of the audit and review described in this plan is to verify compliance with 10 CFR 54.21(a)(3). Therefore, the audit and review process helps ensure that for each structure and component within the scope of the project team's review, the effects of aging will be adequately managed so that the intended function(s) will be maintained consistent with the CLB for the period of extended operation.
The audit and review procedure for WCGS is described in Sections 5 and 6 of this plan. It is intended to accomplish the following objectives:
For WCGS AMPs that the applicant claims are consistent with GALL AMPs, verify that the plant AMPs contain the program elements of the referenced GALL AMP and that the conditions at the plant are bounded by the conditions for which the GALL AMPs were evaluated.
For WCGS AMPs that the applicant claims are consistent with GALL AMPs with exceptions, verify that the plant AMPs contain the program elements of the referenced GALL AMPs and that the conditions at the plant are bounded by the conditions for which the GALL AMPs were evaluated. In addition, verify that the applicant has documented an acceptable technical basis for each exception.
For WCGS AMPs that the applicant claims will be consistent with GALL AMPs after specified enhancements are implemented, verify that the plant AMPs, with the enhancements, will be consistent with the referenced GALL AMPs, or are acceptable on the basis of a technical review. In addition, verify that the applicant identified the enhancements as commitments in the Updated Final Safety Analysis Report (UFSAR) or other docketed correspondence.
Wolf Creek Generating Station AMP and AMR Audit and Review Plan 5
For plant-specific WCGS AMPs, verify the AMPs are acceptable on the basis of a technical review. Use the worksheet provided in Appendix G ro assess the adequacy of the AMPs against 10 program elements described in Branch Technical Position RLSB-1 Aging Management Review - Generic, in Appendix A to the SRP-LR.
For AMR line items that the applicant claims are consistent with the GALL Report, determine that these AMR line items are consistent with the recommendation of the GALL Report.
For AMR line items (Table 1s) that the applicant claims are not applicable with the GALL Report, determine that these AMR line items are acceptable on the basis of a technical review.
For AMR line items that the applicant claims consistent with AMR line items that the staff has previously approved for another plant, determine that these AMR line items are acceptable on the basis of a technical review.
For AMR line items for which the GALL Report recommends further evaluation, determine that the applicant has addressed the further evaluation, and evaluating the AMRs in accordance with the SRP-LR.
For TLAAs, determine that the applicant has properly identified the TLAAs. TLAAs are certain plant-specific safety analyses that are based on explicitly assumed 40-year plant life (for example, aspects of the reactor vessel design). Pursuant to 10 CFR 54.21(c)(1), a license renewal applicant is required to provide a list of TLAAs, as defined in 10 CFR 54.3. The area relating to the identification of TLAAs is reviewed. TLAAs may have developed since issuance of a plants operating license. As indicated in 10 CFR 54.30, the adequacy of the plants CLB, which includes TLAAs, is not an area within the scope of the license renewal review. Any question regarding the inadequacy of the CLB must be addressed under the backfit rule (10 CFR 50.109) and is separate from the license renewal process.
Determine that the applicant has demonstrated that (1) the TLAAs remain valid for the period of extended operation; (2) the TLAAs have been projected to the end of the period of extended operation; or (3) the effects of aging on the intended function(s) will be adequately managed for the period of extended operation.

SUMMARY
OF INFORMATION PROVIDED IN THE LICENSE RENEWAL APPLICATION 4.1 Aging Management Review Results The WCGS LRA closely follows the standard LRA format presented in NEI 95-10, "Industry Guideline for Implementing the Requirements of 10 CFR Part 54 - The License Renewal Rule,"
Revision 6, June 2005. Section 3 of the LRA provides the results of the aging management review for structures and components that the applicant identified as being subject to aging management review.
LRA Table 3.0-1, Table 3.0-2, and Table 3.0-3 provide descriptions of the mechanical, structural, and electrical and instrument and controls service environments, respectively, used in the AMRs to determine the aging effects requiring management. Results of the AMRs are presented in two different types of tables. The applicant refers to the two types of tables as Table 1 and Table 2.
The first table type is a series of six tables labeled Table 3.X.1, where "X" is the system/
component group number (see table below), and "1" indicates it is a Table 1 type. For example, in the reactor coolant system subsection of the LRA Section 3, this is Table 3.1.1, and in the engineered safety features subsection of LRA Section 3, this is Table 3.2.1. For ease of discussion, these table types will hereafter be referred to as "Table 1." These tables are derived from the corresponding tables in NUREG-1801, Volume 1, and present summary information from the AMRs.
Definition 1
Reactor Vessel, Internals, and Reactor Coolant System 2
Engineered Safety Features Systems 3
Auxiliary Systems 4
Steam and Power Conversion Systems 5
Containments, Structures, and Component Supports 6
Electrical and Instrumentation and Controls The second table type is a series of tables labeled Table 3.X.2-Y, where "X" is the system/
component group number, "2" indicates it is a Table 2 type, and "Y" indicates the subgroup number within group "X. For example, within the reactor coolant system subsection, the AMR results for the reactor vessel and internals are presented in Table 3.1.2-1, and the results for the steam generators are in Table 3.1.2-3. In the engineered safety features subsection, the nuclear sampling system results are presented in Table 3.2.2-1, and the containment spray system is in Table 3.2.2-2. For ease of discussion, these table types will hereafter be referred to as "Table 2." These tables present the results of the AMRs.
Wolf Creek Generating Station AMP and AMR Audit and Review Plan 7
4.1.1 WCGS AMR Comparison with the GALL Report The applicant compared the WCGS AMR results with information set forth in the tables of the GALL Report and provided the results of its comparisons in two table types that correlate with the two table types described above.
To take full advantage of the GALL Report, WCGS AMR results have been compared w/
information set forth in the tables of NUREG-1801. Results of that comparison are provided in the following two table types, Table 1 and Table 2.
4.1.1.1 Purpose of Table 1 The purpose of Table 1 is to provide a summary comparison of how the WCGS AMR results align with the corresponding table of NUREG-1801, Volume 1. These tables are essentially the same as Tables 1 through 6 provided in NUREG-1801, Volume 1, with the following exceptions:
The ID column is labeled "Item Number" and the spacing has been expanded to include the table number.
The "Type" column has been deleted. Items applicable to BWRs only are noted as such.
The "Related Generic Item" and Unique Item columns have been replaced by a "Discussion" column.
The "Item Number" column provides a means to cross-reference to Table 1 from the Table 2s.
Further information is provided in the "Discussion" column. The following are examples of information that might be contained within this column:
Any "Further Evaluation Recommended" information or reference to the location of that information.
The name of a plant-specific program being used.
Exceptions to the NUREG-1801 assumptions.
A discussion of how the line item is consistent with the corresponding line item in NUREG-1801, Volume 1, when it may not be intuitively obvious.
A discussion of how the line item is different than the corresponding line item in NUREG-1801, Volume 1, when it may appear to be consistent.
Wolf Creek Generating Station AMP and AMR Audit and Review Plan 8
4.1.1.2 Purpose of Table 2 Table 2 provides results of the aging management reviews for those structures and components identified in Section 2 as being subject to aging management review. There is a Table 2 for each aging management review within a NUREG-1801 system group. For example, the engineered safety features system group contains tables specific to nuclear sampling, containment spray, containment integrated leak rate test, decontamination, liquid radwaste, reactor makeup water, containment purge HVAC, breathing air, hydrogen control, high pressure coolant injection, and residual heat removal.
Table 2 consists of the following nine columns:
Component Type Column 1 identifies the component types from Section 2 of this application that are subject to aging management review. Similar to Section 2, component types are listed in alphabetical order. In the Class 1 tables in Section 3.1 and the structural tables in Section 3.5, component types are alphabetical by sub-groups.
The term "piping" in component lists may include pipe, pipe fittings (such as elbows & reducers),
flow elements, orifices, and thermowells. If such components have unique tag numbers or the specific component has a function other than pressure boundary, then flow elements, orifices and thermowells are identified as a separate component type.
The term "heat exchanger (shell)" may include the bonnet/channel head and tubesheet. In cases where the bonnet/channel head and tubesheet provide a unique material and environment combination, they will be uniquely identified as a separate component type.
The general component type of "tank" includes components identified as tanks or accumulators on LRA drawings.
Intended Function Column 2 identifies the license renewal intended functions (using abbreviations where necessary) for the listed component types. Definitions and abbreviations of intended functions are listed in Table 2.0-1 in Section 2.
Material Column 3 lists the specific materials of construction for the component type being evaluated.
Environment Column 4 lists the environment to which the component types are exposed. Internal/external service environments are indicated. A description of these environments is provided in Tables
Wolf Creek Generating Station AMP and AMR Audit and Review Plan 9
3.0-1, 3.0-2, and 3.0-3 for mechanical, structural, and electrical and instrument and controls components, respectively.
Aging Effect Requiring Management Column 5 lists the aging effects requiring management for material and environment combinations for each component type.
Aging Management Programs (AMP)
Column 6 lists the programs used to manage the aging effects requiring management.
NUREG-1801, Vol. 2, Item Column 7 documents identified consistencies by noting the appropriate NUREG-1801, Volume 2, item number. If there is no corresponding item number in NUREG-1801, Volume 2, for a particular combination of factors, column 7 indicates None for this item.
Each combination of the following factors listed in Table 2 is compared to NUREG-1801, Volume 2, to identify consistencies:
Component type.
Material.
Environment.
Aging effect requiring management.
Aging management program.
Table 1 Item Column 8 lists the corresponding line item from Table 1. If there is no corresponding item in NUREG-1801, Volume 1, column 8 is left blank.
Each combination of the following that has an identified NUREG-1801, Volume 2 item number also has a Table 1 line item reference number:
Component type.
Material.
Environment.
Aging effect requiring management.
Aging management program.
Notes Column 9 contains notes that are used to describe the degree of consistency with the line items in NUREG-1801, Volume 2. Notes that use letter designations are standard notes based on a letter from A. Nelson, NEI, to P. T. Kuo, NRC, U.S. Nuclear Industrys Proposed Standard
Wolf Creek Generating Station AMP and AMR Audit and Review Plan 10 License Renewal Application Format Package, Request NRC Concurrence, dated January 24, 2003 (ML030290201). The staff concurred with the NEI standardized format for license renewal applications by letter dated April 7, 2003, from P. T. Kuo, NRC, to A. Nelson, NEI (ML030990052). Notes that use numeric designators are specific to WCGS.
WCGS LRA Table 2 contains the aging management review results and indicates whether the results correspond to line items in Volume 2 of the GALL Report. Correlations between the combination WCGS LRA Table 2 and a combination for a line item in Volume 2 of the GALL Report are identified by the GALL Report item number in Column 7. If None is indicated in column 7, the applicant did not identify a corresponding combination in the GALL Report. If the applicant identified a GALL Report line item, the next column provides a reference to a Table 1 row number. This reference corresponds to the GALL Report, Volume 2, roll-up to the GALL Report, Volume 1, tables.
4.1.2 Plant-Specific Programs Many of the GALL Report evaluations refer to plant-specific programs. In these cases, the applicant considers the WCGS evaluation to be consistent with the GALL Report if the other elements are consistent. Note E is used to indicate that the AMR line-item is consistent with the GALL Report for material, environment, and aging effect, but a different AMP is credited. The project team will evaluate these line-items to determine that the AMP credited by the applicant is applicable.
4.2 Time-Limited Aging Analyses The WCGS LRA closely follows the standard LRA format presented in Revision 6 of NEI 95-10, Industry Guidelines for Implementing the Requirements of 10 CFR Part 54 - The License Renewal Rule. Section 4 of the WCGS LRA addresses TLAAs. In Section 4.1.1, the WCGS LRA states that the calculations and evaluations that could potentially meet the six criteria of 10 CFR 54.3 were identified by searching CLB documents including the following:
A.
The Updated Safety Analysis Report (USAR)
B.
Technical Specifications C.
The NRC Safety Evaluation Report (SER) for the original operating license D.
All subsequent NRC Safety Evaluations (SEs)
E.
WCNOC and NRC docketed licensing correspondence.
Also, in Section 4.1.1, the WCGS LRA states that as required by 10 CFR 54.21(c)(1), an evaluation of WCGS-specific TLAAs must be performed to demonstrate that:
(i)
The analyses remain valid for the period of extended operation; (ii)
The analyses have been projected to the end of the period of extended operation; or
Wolf Creek Generating Station AMP and AMR Audit and Review Plan 11 (iii)
The effects of aging on the intended function(s) will be adequately managed for the period of extended operation.
In the WCGS LRA, the applicant summarized the results of the above evaluations in Table 4.1-1. These evaluations are discussed in subsequent sections of WCGS LRA Section 4.
Section 4.1.3 of the WCGS LRA identifies plant-specific exemptions. Section 10 CFR 54.21(c) also requires that the application for a renewed license includes a list of plant-specific exemptions granted pursuant to 10 CFR 50.12 and in effect that are based on TLAAs as defined in 10 CFR 54.3. The WCGS performed this by reviewing WCGS docketed correspondence which identified WCGS exemptions. The results of this review determined that 12 WCGS exemptions depend on TLAAs.
The WCGS LRA next includes a separate section for each of the identified TLAAs within the outline of the corresponding NUREG-1800 TLAA category. The TLAA categories are outlined in the next table.

OVERVIEW OF AUDIT, REVIEW, AND DOCUMENTATION PROCEDURE The project team will follow the procedure specified in Section 6 of this plan to perform its audits and reviews and to document the results of its work. The process covered by the procedure is summarized below.
5.1 Aging Management Programs For the WCGS AMPs for which the applicant claimed consistency with the AMPs included in the GALL Report, the project team will review the WCGS AMP descriptions and compare program elements for the WCGS AMPs to the corresponding program elements for the GALL AMPs. The project team will verify that the WCGS AMPs contain the program elements of the referenced GALL program and that the conditions at the plant are bounded by the conditions for which the GALL program was evaluated. Table 1 of this audit and review plan summarizes the program elements that comprise an aging management program. The License Renewal Branch B (RLRB) will review and determine the adequacy of the applicants 10 CFR 50, Appendix B Program.
Other aspects of these program elements will be reviewed by the project team.
For WCGS AMPs that have one or more exception and/or enhancement, the project team will review each exception and/or enhancement to determine whether the exception and/or enhancement is acceptable, and whether the AMP, as modified by the exception and/or the enhancement, would adequately manage the aging effects for which it is credited. In some cases, the project team will identify differences that the applicant did not identify between the WCGS AMPs credited by the applicant and the GALL Report AMPs. In these cases, the project team will review the difference to determine whether the WCGS AMP, as modified by the difference, would adequately manage the aging effects for which it is credited.
For those WCGS AMPs that are not included in the GALL Report (i.e., plant-specific AMPs), the project team will review the AMP against the ten program elements defined in Appendix A of the SRP-LR. The RLRB will review and determine the adequacy of the applicants 10 CFR 50,
Wolf Creek Generating Station AMP and AMR Audit and Review Plan 15 Appendix B Program. Other aspects of these program elements will be reviewed by the project team. On the basis of its reviews, the project team will determine whether these AMPs will manage the aging effects for which they are credited.
5.2 Aging Management Reviews The AMRs in the WCGS LRA fall into three broad categories: (1) AMR results that are consistent with the GALL Report (i.e., those that the GALL Report concludes are adequate to manage aging of the components referenced in the GALL Report), (2) those for which the GALL Report concludes that aging management is adequate, but further evaluation is recommended for certain aspects of the aging management process, and (3) AMR results that are not consistent with or not addressed in the GALL Report. For the first category AMR reviews, the project team will determine (1) whether the AMRs reported by the applicant to be consistent with the GALL Report are indeed consistent with the GALL Report, and (2) whether the AMRs reported by the applicant to be managed using plant-specific AMPs are technically acceptable.
For the second category AMR review, for which the applicant claimed consistency with the GALL Report, and for which the GALL Report recommends further evaluation, the project team will review the applicant's evaluation to determine if it adequately addressed the issues for which the GALL Report recommended further evaluation. For the third category AMR review, the project team will review the results of the AMRs for material, environment, AERM, and AMP combinations to determine the technical adequacy.
5.3 Time-Limited Aging Analyses Generally, the TLAAs in the WCGS LRA fall into the broad category of those that are consistent with the NUREG-1800 TLAA categories. However, there are 12 plant-specific exemptions identified in the WCGS LRA that depend on TLAAs.
For its TLAA reviews, the project team will determine if the applicant had provided adequate information to meet the requirements of 10 CFR 54.21(c)(1) and 10 CFR 54.21(c)(2).
Further, the project team will conduct both regulatory evaluations and technical evaluations to determine, as defined in 10 CFR 54.3, that each TLAA meets the following six criteria:
1.
Involve systems, structures, and components that are within the scope of license renewal, as delineated in 10 CFR 54.4(e).
2.
Consider the effects of aging.
3.
Involve time-limited assumptions defined by the current operating term (40 years).
4.
Determined to be relevant by the applicant in making a safety determination.
5.
Involve conclusions, or provide the basis for conclusions, related to the capability of the system, structure, and component to perform its intended fucntions, as delineated in 10 CFR 54.4(b).
Wolf Creek Generating Station AMP and AMR Audit and Review Plan 16 6.
Contained or incorporated by reference in the CLB.
In addition, the project team will also review the TLAAs to determine if there are emerging issues that should be further evaluated by technical specialists in the NRC Divisions of Component Integrity (DCI) or the Division of Engineering (DE). This is not expected to be an issue for TLAAs for which the applicant claims consistency with 10 CFR 54.21(c)(i) the analyses remain valid for the period of extended operation or 10 CFR 54.21(c)(iii) the effects of aging on the intended function(s) will be adequately managed for the period of extended operation.
For TLAAs for which the applicant claims consistency with 10 CFR 54.21(c)(ii) - the analyses have been projected to the end of the period of extended operation, the audit team leader will be consulted to determine which TLAAs the audit team will be capable of reviewing.
Consideration should be given to project team expertise, past precedent, and complexity of the provided analysis. Candidates for further review by technical specialists could be such as the following:
A.
Reactor Vessel Neutron Embrittlement B.
Plant-Specific TLAAs 5.4 UFSAR Supplement Review Consistent with the SRP-LR, for the AMRs and associated AMPs that it will review, the project team will review the UFSAR supplement that summarizes the applicant's programs and activities for managing the effects of aging for the extended period of operation. The project team will also review any commitments associated with its programs and activities made by the applicant and verify that they are acceptable for the stated purpose.
5.5 Documents Reviewed by the Project Team In performing its work, the project team will rely heavily on the LRA, the audit and review plan, the SRP-LR, and the GALL Report. The project team will also examine the applicant's precedent review documents, its AMP, AMR, and TLAA basis documents (catalogs of the documentation used by the applicant to develop or justify its AMPs, AMRs, and TLAAs), and other applicant documents, including selected implementing procedures, to verify that the applicant's activities and programs will adequately manage the effects of aging on structures and components.
5.6 Status Meeting At the conclusion of its audits and reviews, the project team will debrief the applicant's license renewal staff and management regarding the status of the audits and reviews of the LRA AMPs, AMRs and TLAAs assigned to the project team.
Wolf Creek Generating Station AMP and AMR Audit and Review Plan 17 5.7 Documentation Prepared by the Project Team The project team will prepare an audit and review plan, worksheets, work packages, requests for additional information (RAIs), an audit and review summary, and a safety evaluation report (SER) input. The project team will also prepare questions during site visits and will track the applicant's responses to the questions.
5.7.1 Audit and Review Plan The project team leader will prepare a plant-specific audit and review plan as described herein.
5.7.2 Worksheets Each project team member will informally document the results of his or her work on a variety of worksheets. The worksheets are shown in Appendix F, "Consistent with GALL Report AMP Audit/Review Worksheet"; Appendix G, "Plant-Specific AMP Audit/Review Worksheet"; and Appendix H, "AMR Comparison Worksheets." The use of the worksheets is described in Section 6 of this plan.
5.7.3 Questions As specified in Section 6 of this plan, the project team members will ask the applicant questions during the on-site audits, as appropriate, to facilitate its audit and review activities. The team will also track the applicant's answers to the questions.
5.7.4 Work Packages After each site visit, the project team leader, in conjunction with the project manager, will assemble work packages for any work that the team will refer to the Office of Nuclear Reactor Regulation (NRR) Division of Engineering (DE) or the Division of Component Integrity (DCI) for review. Each work package will include a work request and any applicable background information on the review item that was gathered by the project team.
5.7.5 Requests for Additional Information The review process described in this plan is structured to resolve as many questions as possible during the site visits. As examples, the site visits are used to obtain clarifications about the LRA and explanations as to where certain information may be found in the LRA or its associated documents. Nevertheless, there may be occasions where an RAI is appropriate to obtain information to support a SER finding. The need for RAIs will be determined by the project team leader during the in-office project staff review or during site visits through discussions with the individual project team members. When the project team leader determines that an RAI is needed, the project team member who is responsible for the area of review will prepare the RAI.
RAIs will include the technical and regulatory basis for requesting the information.
Wolf Creek Generating Station AMP and AMR Audit and Review Plan 18 After the NRC receives a response to an RAI from the applicant, the team leader will provide the response to the team member who prepared the RAI. The team member will review the response and determine if it resolves the issue that was the reason for the RAI. The team member will document the disposition of the RAI in the SER input.
5.7.6 Audit and Review Summary At the conclusion of the audits and reviews, the project team will prepare a summary of the audits and reviews highlighting the status of its review and any potential RAIs.
5.7.7 Safety Evaluation Report Input The project team will prepare SER input, based on its audit and review, as described in Section 6.5.2 of this plan.
6.

Wolf Creek Generating Station AMP and AMR Audit and Review Plan 20 6.2 Aging Management Program (AMP) Audits and Reviews 6.2.1 Types of AMPs There are two types of AMPs: those that the applicant claims are consistent with AMPs contained in the GALL Report, and those that are plant-specific. The process for auditing and reviewing both types of AMPs is presented in the following sections of this plan.
6.2.2 Scope of AMP Elements to be Audited and Reviewed Table 1 of this plan shows the 10 program elements that are used to evaluate the adequacy of each aging management program. These program elements are presented in Branch Technical Position (BTP) RLSB-1, "Aging Management Review - Generic," in Appendix A of the SRP-LR, and are summarized in the GALL Report.
The program elements audited or reviewed is the same for both AMPs that are consistent with the GALL Report and for plant-specific AMPs. The RLRB will reveiw and determine the adequacy of the applicants 10 CFR 50, Appendix B Program. Other aspects of these program elements will be reviewed by the project team.
6.2.3 Plant AMPs that Are Consistent with the GALL Report Figure 1, "Audit of AMPs that Are Consistent with the GALL Report," is the process flowchart that shows the activities and decisions used by the project team to review and audit each plant AMP that the applicant claims is consistent with the GALL Report.
Preparation A.
For the plant AMP being reviewed, identify the corresponding GALL AMP.
B.
Review the associated GALL AMP and identify those elements that will be audited.
C.
Identify the documents needed to perform the audit. These may include, but are not limited to, the following:
1.
GALL Report 2.
SRP-LR 3.
ISGs 4.
RAIs and SERs for similar plants 5.
LRA 6.
Basis documents 7.
Implementation procedures 8.
Operating experience reports (plant-specific and industry) 9.
Wolf Creek Generating Station AMP and AMR Audit and Review Plan 21 Audit/Review A.
Confirm that WCGS AMP program elements are consistent with the corresponding elements of the GALL Report AMP by answering the following questions and then following the process shown in Figure 1.
1.
Did the applicant identify any exceptions to the GALL Report AMP?
2.
Did the applicant identity any enhancements to the GALL Report AMP?
3.
Are the elements consistent with the GALL Report AMP?
B.
If either of the above questions results in the identification of an exception/enhancement or a difference to the GALL AMP, determine whether it is acceptable on the basis of an "adequate technical justification."
C.
If an acceptable basis exists for an exception/enhancement or difference, document the basis in the worksheet and later the SER input.
D.
Review the industry and plant-specific operating experience associated with the AMP. The review is to identify aging effects requiring management that are not identified by the industry guidance documents (such as EPRI tools) and to confirm the effectiveness of aging management programs. The project team members should consider the industry guidance when assessing operating experience and formulating questions for the applicant. The industry guidance (from NEI 95-10, Revision 6) is as follows:
1.
Plant-Specific Operating Experience with Aging Effects Requiring Management. A plant-specific operating experience review should assess the operating and maintenance history. A review of the prior 5 to 10 years of operating and maintenance history should be sufficient. The results of the review should confirm consistency with documented industry operating experience. Differences with previously documented industry experience such as new aging effects or lack of aging effects allow consideration of plant-specific aging management requirements.
2.
Plant-Specific Operating Experience with existing Aging Management Programs. The operating experience of AMPs, including corrective actions resulting in program enhancements or additional programs, should be considered. The review should provide objective evidence to support the conclusion that the effects of aging will be managed so that the intended function(s) will be maintained during the extended period of operation.
Guidance for reviewing industry operating experience is presented in BTP RLSB-1 in Appendix A.1 of the Branch Technical Positions in NUREG-1800.
3.
Industry Operating Experience. Industry operating experience and its applicability should be assessed to determine whether it changes
Wolf Creek Generating Station AMP and AMR Audit and Review Plan 22 plant-specific determinations. NUREG-1801 is based upon industry operating experience prior to its date of issue. Operating experience after the issue date of NUREG-1801 should be evaluated and documented as part of the aging management review. In particular, generic communications such as a bulletin, a generic letter, or an information notice should be evaluated for impact upon the AMP. The evaluation should check for new aging effects or a new component or location experiencing an already identified aging effect.
E.
If it is necessary to ask the applicant a question to clarify the basis for accepting a program element, or an exception or a difference to the GALL Report AMP, follow the logic process shown in Figure 1.
F.
If it is necessary for the applicant to submit additional information to support the basis for accepting the justification, an exception, or a difference to a program element, the applicant may agree to voluntarily submit the required information as a supplement (docketed letter submitted under oath and affirmation) to the LRA.
If not, the NRC may issue an RAI to obtain the information.

Audit/review the WCGS AMP program elements and determine that they are in accordance with the acceptance criteria for the corresponding program elements of Section A.1.2.3 of the SRP-LR.
B.
Review the industry and plant-specific operating experience associated with the AMP. This is an area of review emphasis. The review is to identify aging effects requiring management that are not identified by the industry guidance documents (such as EPRI tools) and to confirm the effectiveness of aging management programs. The project team members should consider the industry guidance when assessing operating experience and formulating questions for the applicant.
The industry guidance (from NEI 95-10, Revision 6) is as follows:
1.
Plant-Specific Operating Experience with Aging Effects Requiring Management. The review should assess the operating and maintenance history. A review of the prior 5 to 10 years of operating and maintenance history should be sufficient. The results of the review should confirm consistency with documented industry operating experience. Differences with previously documented industry experience such as new aging effects or lack of aging effects allow consideration of plant-specific aging management requirements.
2.
Plant-Specific Operating Experience with Aging Management Programs.
The operating experience of aging management programs, including past corrective actions resulting in program enhancements or additional programs, should be considered. The review should provide objective evidence to support the conclusion that the effects of aging will be managed so that the intended function(s) will be maintained during the extended period of operation. Guidance for reviewing industry operating experience is presented in BTP RLSB-1 in Appendix A.1 of the Branch Technical Positions in NUREG-1800.
3.
Industry Operating Experience. Industry operating experience and its applicability should be assessed to determine whether it changes plant-specific determinations. NUREG-1801 is based upon industry operating experience prior to its date of issue. Operating experience after the issue date of NUREG-1801 should be evaluated and documented as part of the aging management review. In particular, generic communications such as a bulletin, a generic letter, or an information notice should be evaluated for impact upon the AMP. The evaluation should check for new aging effects or a new component or location experiencing an already identified aging effect.

The AMR line item letter notes are based on a letter from A. Nelson, NEI, to P. T. Kuo, NRC, "U.S. Nuclear Industry's Proposed Standard License Renewal Application Format Package, Request NRC Concurrence," dated January 24, 2003 (ML030290201). The staff concurred in the format of the standardized format for LRAs by letter dated April 7, 2003, from P.T. Kuo, NRC, to A. Nelson, NEI (ML030990052).
2 Some GALL AMRs reference the use of a plant-specific AMP. In such cases the AMR audit requires the project team member to confirm that the plant-specific AMP is appropriate to manage the aging effects during the period of extended operation.
25 9.
UFSAR 10.
Lessons Learned Developed by RLRC Audit/Review A.
Each AMR line item is coded with a letter which represents a standard note designation.1 The letter notes are described in Table 2 of this plan. Notes that use numeric designators are plant-specific. The note codes A though E are classified as "consistent with the GALL Report," and will be reviewed in accordance with the guidance contained in this plan.
B.
The AMR review involves verification that the applicant has satisfied the requirements of 10 CFR 54.21(a)(3). This requirement states: For each structure and component... [within the scope of this part... and... subject to an aging management review] (the applicant) demonstrate(s) that the effects of aging will be adequately managed so that the intended function(s) will be maintained consistent with the CLB for the period of extended operation.
C.
Determine compliance by following the process shown in Figure 3. The process is summarized below:
1.
For each AMR line item, perform the review associated with the letter note (A through E) assigned to the AMR line item. Specifically, determine if the AMR is consistent with the GALL Report for the elements associated with its note.
2.
If Note A applies, and the applicant uses a plant-specific AMP2 determine if the component is within the scope of the cited plant AMP. If the component is within the scope of the plant AMP, the AMR line item is acceptable. If not acceptable, go to Step (7) below.
3.
If Note B applies, review the LRA exceptions and document the basis for acceptance in the worksheet, and later in the SER input. If not acceptable, go to Step (7) below.
Wolf Creek Generating Station AMP and AMR Audit and Review Plan 26 4.
If Note C or D applies, determine if the component type is acceptable for the material, environment, and aging effect. If Note D applies, also review the LRA exceptions and document the basis for acceptance in the worksheet, and later in the SER input. If not acceptable, go to Step (7) below.
5.
If Note E applies, review the AMP audit report findings to determine if the scope of the alternate AMP envelopes the AMR line item being reviewed and satisfies 10 CFR 54.21(a)(3). If it does not, go to Step (7) below.
6.
Review the corresponding LRA Table 3.X.1 entry that is referenced in LRA Table 3.X.2.Y. If applicable, determine whether the applicant's "Further Evaluation Recommended" response in LRA Section 3.X.2.2.Z is enveloped by Section 3.X.2.2.Z of the SRP-LR. If not, go to Step (7) below. If the LRA section does not meet the acceptance criteria of Appendix A of the SRP-LR, go to Step (7) below.
7.
If during the review a difference is identified, prepare a question to the applicant, in order to obtain clarification.
a.
Review the applicant's response to the question. If it appears acceptable, document the basis for acceptance and re-start the audit/review for the AMR line item from Step (1) above.
b.
If the applicant's response does not resolve the question or issue, prepare an additional question to obtain the information needed to achieve resolution. Review the applicant's response to the second question. If it appears acceptable, document the basis for acceptance and re-start the audit/review for the AMR line item from Step (1) above.
c.
If it is necessary for the applicant to submit additional information to resolve a question or an issue or to support a basis or conclusion, the applicant may submit the information as a supplement to the LRA or the NRC may issue an RAI to obtain the information. The team leader should be consulted if docketed information may be needed.
8.
Review LRA Table 3.X.1. for AMR line items (Table 1s) that the applicant claims are not applicable with the GALL Report, determine that the AMR line items are acceptable on the basis of a technical review.
AMR Audit/Review Worksheets Document the audits/reviews of plant AMRs using the worksheet provided in Appendix H, "AMR Comparison Worksheets," or on spreadsheets containing similar information.
Wolf Creek Generating Station AMP and AMR Audit and Review Plan 27 6.3.2 Plant AMRs that Are Not Consistent with the GALL Report Review LRA Tables 3.X.2.1 - X (Table 2s) for LRA Sections 3.1 thru 3.6, where the applicant indicated, via Notes F through J, that the combination of component type, material, environment, and AERM does not correspond to a line item in the GALL Report. Specifically, Note F indicates that the material for the AMR line item component is not evaluated in the GALL Report. Note G indicates that the environment for the AMR line item component and material is not evaluated in the GALL Report. Note H indicates that the aging effect for the AMR line item component, material, and environment combination is not evaluated in the GALL Report. Note I indicates that the aging effect identified in the GALL Report for the line item component, material, and environment combination is not applicable. Note J indicates that neither the component nor the material and environment combination for the line item is evaluated in the GALL Report. For component groups not evaluated in the GALL Report (notes F-J), the project team reviews the applicant's evaluation in accordance with Branch Technical Position RLSB-1 (Appendix A.1 of the SRP-LR) to determine the technical adequacy. If during the review a difference is identified, prepare a question to the applicant, in order to obtain clarification. Review the applicant's response to the question and confirm that it is acceptance in accordance with Appendix A.1 of the SRP-LR.
The AMR review involves verification that the applicant has satisfied the requirements of 10 CFR 54.21(a)(3). This requirement states: For each structure and component... [within the scope of this part... and... subject to an aging management review] (the applicant) demonstrate(s) that the effects of aging will be adequately managed so that the intended function(s) will be maintained consistent with the CLB for the period of extended operation.
6.4 Time-Limited Aging Analyses (TLAA) Audits and Reviews Audit and review of TLAAs are discussed below. The project team will also review the TLAAs to determine if there are emerging issues that should be further evaluated by technical specialists in the NRC Divisions of Component Integrity (DCI) or the Division of Engineering (DE). In general, the project team will review TLAAs that are for which the applicant claims consistency with 10 CFR 54.21(c)(i) the analyses remain valid for the period of extended operation. or 10 CFR 54.21(c)(iii) the effects of aging on the intended function(s) will be adequately managed for the period of extended operation. For TLAAs for which the applicant claims consistency with 10 CFR 54.21(c)(ii) - the analyses have been projected to the end of the period of extended operation, the audit team leader will be consulted to determine which TLAAs the audit team will be capable of reviewing. Consideration should be given to team expertise, past precedent, and complexity of the provided analysis.
6.4.1 Identify Generic TLAA Issues Figure 4, Evaluation of TLAAs and Exemptions, taken from NEI 95-10, Revision 6, shows the process of evaluating and reviewing TLAAs and also identifying the exemptions in effect. This process flowchart shows the activities and decisions used to audit/review each TLAA that the applicant identifies.
