| ==1.0INTRODUCTION==
| |
| The purpose of this report is to provide summary information from the aging management reviews performed for the Vermont Yankee Nuclear Power Station (VYNPS), including comparison of the results with the evaluations documented in NUREG-1801, Generic Aging Lessons Learned (GALL) Report (Reference 2). NUREG-1801, also known as the GALL report, contains the NRC's generic evaluation of existing plant programs and documents the technical basis for determining where existing programs are adequate without modification and where existing programs should be augmented for the extended period of operation. The NRC evaluated the adequacy of programs to manage certain aging effects for particular structures or components. If the programs at the applicant's facility correspond to those reviewed in the GALL report, an applicant may reference NUREG-1801 and no further staff review is required.This report covers Class 1 mechanical, non-Class 1 mechanical, structural, and electrical systems. The subsections in Section 3 of this report are numbered to correspond to the license renewal application (LRA) subsections to facilitate the preparation of Section 3 of the LRA.This report is prepared based on guidance provided in LRPG-10 (Reference 10). For additional information on the license renewal project scope and documentation, refer to the license renewal project plan (Reference 9

| ).

| | |
| ==1.1BACKGROUND==
| |
| | |
| The purpose of Section 3 of the license renewal application is to present the results of the aging management reviews. The NRC reviews this information to determine if the appropriate aging effects are identified and if the credited aging management program is adequate to manage the aging effects for the period of extended operation. To assist in this review, the NRC published NUREG-1801, Volumes 1 and 2, which documents the NRC's evaluat ions of generic programs. The intent was to generically evaluate the adequacy of common programs to manage the aging effects of specific environments on certain components. Utilities could then refer to the NUREG-1801 evaluation of the program and the NRC would not need to review such programs for each utility.Past methods of conducting and documenting the comparisons to NUREG-1801 varied greatly among applications, causing lack of efficiency in the review which lead to unnecessary requests for additional information. To resolve these difficulties, an industry effort coordinated by the Nuclear Energy Institute (NEI) developed a standardized format to present the information in the LRA, including the comparison to NUREG-1801. This standardized format included tables for Section 3 of the LRA and a set of reference notes, indicated by a letter designation, that are standard throughout the industry. The standardized format is Appendix D in Revision 6 of NEI 95-10 (Reference 4
| |
| ).The goal is to deliver the appropriate information, presented in the best way possible, to document the results of the aging management reviews and the comparison of those results to the evaluations in NUREG-1801. To achieve this goal, this report uses the standardized format developed by NEI.

| Vermont Yankee License Renewal ProjectLRPD-06 Revision 0Page 10 of 488Aging Management Review Summary1.2METHODIn each aging management review report (AMRR), tables provide the results summarized by component type (e.g., Attachment 2 tables in mechanical system AMRRs). The AMRR results have been compared to line items in NUREG-1801 Volume 2 and the comparison documented in the tables in Section 3 of this report. The format of the Section 3 tables follows the standardized format.In NUREG-1801, the component level tables for each system in Volume 2 are summarized by tables in Volume 1. This report is similarly organized. The component level tables for each system present the results of the aging management review and the comparable line item (if any) from NUREG-1801. These tables are referred to as "Table 2" in the following description. There is a Table 2 system table for each AMRR. Those components that re ference a NUREG-1801 line item are cross-referenced to summary tables ("Table 1") that correspond to the summary tables in NUREG-1801 Volume 1.For further details of the method used to compile the AMRS report, see LRPG-10 (Reference 10).1.3TABLE USAGETable 1Information in the following columns is taken directly from NUREG-1801, Volume 1.

If the column is blank, no appropria tely corresponding comb ination in NUREG-1801, Volume 2, was identified.If a NUREG-1801, Volume 2, line item is identified, the next column provides a reference to a Table 1 row number. This reference corresponds to the NUREG-1801, Volume 2, "roll-up" to the NUREG-1801, Volume 1, tables.The last column 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 NEI 95-10, Appendix D (Reference 4). Notes that use numeric designators are specific to VYNPS.Many of the NUREG-1801 evaluations refer to plant-specific programs. By NRC request, Note E is used In these cases (consistent but different program credited).

| |
| As discussed in Reference 4, the NRC has encouraged applicants for license renewal to address proposed ISGs in the LRA. The following list is from Reference 5. The NRC staff has identified these issues for which additional staff and industry guidance clarification may be necessary:ISG-1GALL Report Presenting One Acceptable Way to Manage Aging Effects for License RenewalISG-2Scoping of Equipment Relied On to Meet the Requirements of the Station Blackout (SBO) Rule for License RenewalISG-3Aging Management Program of Concrete ISG-4Aging Management of Fire Protection System for License RenewalISG-5Identification and Treatment of Electrical Fuse Holders for License RenewalISG-6Identification and Treatment of Housings for Active Components for License RenewalISG-7Scoping Guidance for Fire Protection Equipment for License RenewalISG-8Updating the Improved License Renewal Guidance Documents - ISG ProcessISG-9Identification and Treatment of Structures, Systems and Components Which Meet 10 CFR 54.4(a)(2)ISG-10Standardized Format for License Renewal Applications ISG-11Aging Management of Environmental Fatigue for Carbon/Low-Alloy SteelISG-12Operating Experience with Cracking of Class 1 Small-Bore PipingISG-13Management of Loss of Preload on Reactor Vessel Internals Bolting Using the Loose Parts Monitoring SystemISG-14Operating Experience with Cracking in BoltingISG-15Revision to Generic Aging Lessons Learned Aging Management Program (AMP) XI.E2ISG-16Time-Limited Aging Analyses Supporting Information for License Renewal ApplicationsISG-17Bus Ducts (Iso-phase and Non-segregated) for Electrical Bus BarISG-18Revision to GALL AMP XI.E3 for Inaccessible Cable (Medium Voltage)

| |
| Vermont Yankee License Renewal ProjectLRPD-06 Revision 0Page 15 of 488Aging Management Review Summary NRC considers ISG-7 withdrawn and closed (Reference 6). The jockey pump casing has been added to the revised license renewal guidance documents. No other guidance is needed.
| |
| NRC considers ISG-8 and ISG-10 completed and closed. These ISGs are process related documents and were not included in NRC license renewal guidance documents. The standardized format for LRAs is included in the revision to NEI 95-10.NRC considers ISG-11 closed. The staff concluded there was insuffic ient technical basis provided to justify the elimination of the fatigue evaluation of carbon and low alloy steel components for the effects of the reactor coolant environment. Aging management of environmental fatigue for carbon/low-alloy steel items is discussed in Section4.3.3.1
| |
| .NRC considers ISG-12 withdrawn and closed. NUREG-1801 Section XI.M35, "One-Time Inspection of ASME Code Class 1 Small-Bore Piping," includes the staff's established position and has been added to the revised license renewal guidance documents.
| |
| NRC considers ISG-19A withdrawn and closed.
| |
| Proposed aging management program XI.M11-A has been incorporated into the revised license renewal guidance documents.ISG-19B is only applicable to PWRs.
| |
| ISG-22 is closed. The staff concluded that NUREG-1801 adequately addresses the issue and no ISG is needed.The remaining ISGs are discussed below.ISG-9Identification and Treatment of Structures, Systems and Components Which Meet 10 CFR 54(a)(2)10 CFR 54.4(a)(2) states that SSCs within the scope of license renewal shall include nonsafety-related SSCs whose failure could prevent the satisfactory accomplishment of any of the functions identified for safety-related SSCs.The process used to identify the in-scope nonsafety-related SSCs under 10CFR 54.4(a)(2), discussed in Section 2.1.1.2, is consistent with the guidance provided in NEI95-10 Appendix F (Reference 4
| |
| ), which has been endor sed by the NRC in RG1.188.ISG-23Replacement Parts Necessary to Meet 10 CFR 50.48 (Fire Protection)A review for replacement parts necessary to meet 10CFR50.48 identified a spare cable in the reactor building that is used to repower the inboard shutdown cooling isolation valve for control room cable vault fires. This cable is an installed spare that is included in the aging management review of insulated cables and connections. 2.2GENERIC SAFETY ISSUESIn accordance with the guidance in NEI 95-10, review of NRC generic safety issues as part of the license renewal process is required to satisfy the finding required by 10CFR54.29. GSIs that involve an issue applicable to VYNPS related to the license renewal aging management review Vermont Yankee License Renewal ProjectLRPD-06 Revision 0Page 16 of 488Aging Management Review Summaryor time-limited aging analysis evaluations are to be addressed in the LRA. Based on NUREG-0933, A Prioritization of Generic Safety Issues (Supplement 28), Entergy Operations has identified the following GSIs to be addressed in the application.GSI-168, Environmental Qualification of Electrical Equipment This issue was resolved with no new requirements for licensees (Reference 7). The staff concluded that the existing equipment qualification process was adequate to ensure that I&C cables would perform their intended function. Environmental qualification evaluations of electrical equipment are identified as time-limited aging analyses for VYNPS and addressed in Section 4.4
| |
| .GSI-190, Fatigue Evaluation of Metal Components for 60-Year Plant LifeThis GSI addresses fatigue life of metal components and was closed by the NRC (Reference 8). In the closure letter, however, the NRC concluded that licensees should address the effects of reactor coolant environment on component fatigue life as aging management programs are formulated in support of license renewal. Accordingly, the issue of environmental effects on component fatigue life is addressed in Section 4.3.3.1
| |
| .Based on the above, the GSI review determined that the issues involving either aging effects for SCs subject to an aging management review or TLAAs are already being evaluated for license renewal.2.3COMPONENTS, INTENDED FUNCTIONS, AND ENVIRONMENTS USED IN AMRS 2.3.1Components and Intended FunctionsThe term "piping" in component lists may include pipe, pipe fittings (such as elbows and 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.Table 2.3-1 gives the expanded definitions of intended functions used in this application for structures and components. The tables in the application may refer to either the intended function name or to the abbreviation. Table 2.3-1 will be Table 2.0-1 in the LRA.

| Vermont Yankee License Renewal ProjectLRPD-06 Revision 0Page 18 of 488Aging Management Review SummaryMechanical System DrawingsLicense renewal drawings were prepared to indicate portions of systems that support system intended functions within the scope of license renewal (with the exception of those systems in scope for 10 CFR 54.4(a)(2) for physical interactions, as discussed below). In addition, the drawings identify components that are subject to aging management review. Boundary flags are used in conjunction with safety-to-nonsafety class breaks to identify the system intended function boundaries. Boundary flags are noted on the drawings as system intended function boundaries. Components within these boundary flags and class breaks support system intended functions within the scope of license renewal. Components subject to aging management review (i.e., passive, long-lived components that support system intended functions) are highlighted using color coding to indicate which system aging management review evaluated the components. Drawings that contain only highlighting (no boundary flags) indicate that all components on the drawing support system intended functions unless excluded by safety-to-nonsafety class breaks.Flexible elastomer hoses/expansion joints that are periodically replaced (not long-lived) and therefore not subject to aging management review are indicated as such on the drawings. Safety-related instrument air solenoid valves that open to relieve pressure and fail to a safe position upon loss of pressure boundary do not require aging management review but do support a system intended function. To improve the legibility of the drawings, these components are not marked individually on the drawing using boundary flags.Components that are subject to aging management review based only on the criterion of 10CFR 54.4(a)(2) for physical interactions are not indicated on license renewal drawings. The determination of whether a component meets this criterion is based on where it is located in a building and its proximity to safety-related equipment or where a structural/seismic boundary exists. This information is not provided on flow diagrams and as a result, highlighting the drawings would not provide useful information in determining if components are required to be included for 10CFR 54.4(a)(2) and subject to aging management review.2.3.2EnvironmentsSection 3.0 of the standard license renewal application (see Appendix D of Reference 4) has tables which describe the service environments used in the aging management reviews. The SRESupport for Criterion (a)(3) equipmentProvide structural or functional support to equipment required to meet the Commission's regulations for the five regulated events in 10 CFR 54.4(a)(3).SSRSupport for Criterion (a)(1) equipmentProvide structural or functional support for safety-related equipment.STRStructural integrityMaintain structural integrity such that loose parts are not introduced into the system.Table 2.3-1Intended Functions: Abbreviations and Definitions (Continued)AbbreviationIntended FunctionDefinition Vermont Yankee License Renewal ProjectLRPD-06 Revision 0Page 19 of 488Aging Management Review Summaryenvironments may be internal and external surfaces.

These water types include treated water, reactor coolant and closed cycle cooling water as defined in NUREG-1801. In the Table 2 results, the type of water can be normally be inferred from the context of the result (e.g., if water chemistry control - closed cooling water is the aging management program, then the treated water is equivalent to closed cycle cooling water as defined by NUREG-1801). Where such an inference is not clear, a plant specific note identifies the water type. For the comparison of the aging management review results with those of NUREG-1801, as presented in the last three Table 2 columns, and for the summary of results discussed in Table 1, the NUREG-1801 definitions of water types were used. In other words, the "treated water" listed in the results was compared to the corresponding water type of NUREG-1801. The discussions in Table 1, and in the text sections referenced in Table 1 for further evaluation, use the water types defined by NUREG-1801. In these discussions, "treated water" refers only to water controlled by the water chemistry control - BWR program.EnvironmentDescriptionProtected from weatherAir with temperature less than 150°F, humidity up to 100% and protected from precipitationExposed to weather (includes above grade and below grade)Exposed to the weather with air temperature less than 115°F, humidity up to 100%Exposed to fluid environmentFluid environment at VYNPS is defined as raw water or treated water.

Items potentially treatable as consumables have been evaluated consistently with the information presented in T able 2.1-3 of NUREG-1800. Consumables have been divided into the following four categories for the purpose of license renewal: (a) packing, gaskets, component seals, and O-rings; (b) structural sealants; (c) oil, grease, and component filters; and (d) system filters, fire extinguishers, fire hoses, and air packs.2.4.1Packing, Gaskets, Component Seals, and O-RingsPacking, gaskets, component mechanical seals, and O-rings are typically used to provide a leak-proof seal when components are mechanically joined together. These items are commonly found in components such as valves, pumps, heat exchangers, ventilation units or ducts, and piping segments.

| Based on ANSI B31.1 and the ASME B&PV Code Section III, the subcomponents of pressure retaining components as shown above are not pressure-retaining parts. Therefore, these subcomponents are not relied on to form a pressure-retaining function and are not subject to aging management review.2.4.2Structural SealantsElastomers and other materials used as structural sealants are subject to aging management review if they are not periodically replaced and they perform an intended function, typically supporting a pressure boundary, flood barrier, or rated fire barrier.Seals and sealants, including pressure boundary sealants, compressible joints and seals, seismic joint filler, and waterproofing membranes are included in the aging management review of bulk commodities [LRA] (Section 2.4.6).Table 2.3-4Service Environments for Electrical Aging Management ReviewsEnvironmentDescriptionHeat and airIndoor air at normal operating temperature.Radiation and airNormal plant operating radiation levels.

| Vermont Yankee License Renewal ProjectLRPD-06 Revision 0Page 23 of 488Aging Management Review Summary2.4.3Oil, Grease, and FiltersOil, grease, and component filters have been treated as consumables because either (1) they are periodically replaced or (2) they are monitored and replaced based on condition.2.4.4System Filters, Fire Extinguishers, Fire Hoses, and Air PacksComponents such as system filters, fire hoses, fire extinguishers, self-contained breathing apparatus (SCBA), and SCBA cylinders are considered to be consumables and are routinely tested, inspected, or replaced. Fire protection at VYNPS complies with the applicable safety standards (NFPA-10 for fire extinguishers; NFPA-1962 for fire hoses; 29 CFR 19.10, 29 CFR 19.26, 42 CFR 84, NUREG/CR-0041, and ANSI-Z88.2 for air packs), which specify performance and condition monitoring programs for these specific components. Fire hoses and fire extinguishers are inspected and hydrostatically tested periodically and must be replaced if they do not pass the test or inspection. SCBA and SCBA cylinders are inspected and periodically tested and must be replaced if they do not pass the test or inspection. Fire protection procedures specify the replacement criterion of these components that are routinely checked by tests or inspections to assure operability. Therefore, while these consumables are in the scope of license renewal, they do not require an AMR.

Section 3.1.2.2 of NUREG-1800 discusses these aging effects th at require further evaluation. The following sections are numbered in accordance with the discussions in NUREG-1800 and explain the VYNPS approach to these areas requiring further evaluation. Programs are described in Appendix B
| |
| .3.1.2.2.1Cumulative Fatigue DamageFatigue is a TLAA as defined in 10 CFR 54.3. TLAAs are evaluated in accordance with 10CFR 54.21(c). The evaluation of fatigue for the reactor vessel and the reactor internals is discussed in Sections 4.3.1.1 and 4.3.1.2, respectively. The evaluation of fatigue as a TLAA for the Class 1 portions of the reactor coolant boundary piping and components, including those for interconnecting systems, is discussed in Section 4.3.1.3.3.1.2.2.2Loss of Material Due to General, Pitting, and Crevice Corrosion1.Loss of material due to general, pitting, and crevice corrosion in steel components of the reactor pressure vessel exposed to reactor coolant is managed at VYNPS by the water chemistry control-BWR program. The effectiveness of the water chemistry control-BWR program will be confirmed by the one-time inspection program through an inspection of a representative sample of components crediting this program including areas of stagnant flow. The inservice inspection program supplements the water chemistry control - BWR program for these components.2.This paragraph in NUREG-1800 pertains to BWR isolation condenser components. VYNPS does not have an isolation condenser, however, loss of material due to general, pitting, and crevice corrosion in other steel components within the reactor coolant pressure boundary exposed to reactor coolant is managed by the water chemistry control-BWR program. The effectiveness of the Vermont Yankee License Renewal ProjectLRPD-06 Revision 0Page 29 of 488Aging Management Review Summarywater chemistry control-BWR program will be confirmed by the one-time inspection program through an inspection of a representative sample of components crediting this program including areas of stagnant flow. For some components, the inservice inspection program supplements the water chemistry control - BWR program.3.Loss of material due to general, pitting, and crevice corrosion in stainless steel, nickel-alloy and steel with stainless steel cladding components of the reactor pressure vessel, and loss of material in stainless steel (including CASS) components of the reactor coolant pressure boundary exposed to reactor coolant is managed at VYNPS by the water chemistry control-BWR program. The effectiveness of the water chemistry control-BWR program will be confirmed by the one-time inspection program through an inspection of a representative sample of components crediting this program including areas of stagnant flow. The one-time inspection program is also used to manage loss of material for the main steam flow restrictors by means of a component specific inspection. For some components, the inservice inspection or BWR vessel internals program supplements the water chemistry control - BWR program.4.This paragraph in NUREG-1800 applies to PWRs only.3.1.2.2.3Loss of Fracture Toughness due to Neutron Irradiation Embrittlement1.Neutron irradiation embrittlement is a TLAA evaluated for the period of extended operation in accordance with 10 CFR 54.21(c). The evaluation of loss of fracture toughness for the reactor vessel beltline shell, and welds is discussed in Section 4.2.2.The reactor vessel surveillance program manages reduction of fracture toughness due to neutron embrittlement of reactor vessel beltline materials. VYNPS is a participant in the Boiling Water Reactor Vessel and Internals Project (BWRVIP) Integrated Surveillance Program (ISP) (see reactor vessel surveillance program in Appendix B). This program monitors changes in the fracture toughness properties of ferritic materials in the reactor pressure vessel (RPV) beltline region.3.1.2.2.4Cracking due to Stress Corrosion Cracking (SCC) and Intergranular Stress Corrosion Cracking (IGSCC)1)The water chemistry control - BWR and one-time inspection programs will manage cracking due to SCC and IGSCC in the stainless steel head seal leak detection lines. The one-time inspection program will include a volumetric examination for the detection of cracking.2)This paragraph in NUREG-1800 pertains to BWR isolation condenser components. VYNPS does not have an isolation condenser.3.1.2.2.5Crack Growth due to Cyclic LoadingThis paragraph in NUREG-1800 applies to PWRs only.

At VYNPS, these lines have no license renewal intended function and thus are not subject to aging management review. The lines inside the vessel do not form part of the RCS pressure boundary and their failure would not affect the performance of any functions in the scope of license renewal. However, the lines outside the vessel are part of the RCS pressure boundary and are subject to aging management review.2.This paragraph in NUREG-1800 pertains to BWR isolation condenser components. VYNPS does not have an isolation condenser.3.1.2.2.9Loss of Preload due to Stress RelaxationThis paragraph in NUREG-1800 applies to PWRs only.3.1.2.2.10Loss of Material due to ErosionThis paragraph in NUREG-1800 applies to PWRs only.3.1.2.2.11Cracking due to Flow-Induced VibrationCracking due to flow-induced vibration in the stainless steel steam dryers is managed by the BWR vessel internals program. The BWR vessel internals program currently incorporates the guidance of GE-SIL-644, Revision 1. VYNPS will evaluate BWRVIP-139 once it is approved by the staff and either include its recommendations in the VYNPS BWR vessel internals program or inform the staff of VYNPS's exceptions to that document.3.1.2.2.12Cracking due to Stress Corrosion Cracking and Irradiation-Assisted Stress Corrosion Cracking (IASCC)This paragraph in NUREG-1800 applies to PWRs only.3.1.2.2.13Cracking due to Primary Water Stress Corrosion Cracking (PWSCC)This paragraph in NUREG-1800 applies to PWRs only.

These topics are addressed in Section 4.3.1.3ConclusionThe reactor vessel, internals and reactor coolant system components that are subject to aging management review have been identified in accordance with the requirements of 10CFR54.21. The aging management programs selected to manage aging effects for the reactor vessel, internals and reactor coolant system components are identified in Section 3.1.2.1 and in the following tables
| |
| . A description of these aging management programs is provided in Appendix B , along with the demonstration that the identified aging effects will be managed for the period of extended operation.Therefore, based on the demonstrations provided in Appendix B, the effects of aging associated with the reactor coolant system components will be managed such that there is reasonable assurance that the intended functions will be maintained consistent with the current licensing basis during the period of extended operation.

VYNPS is a BWR and does not have charging pumps or steel pump casings with stainless steel cladding. This item is not applicable to VYNPS.3.2.2.2.3Loss of Material due to Pitting and Crevice Corrosion1.Loss of material due to pitting and crevice corrosion for internal surfaces of stainless steel piping and components in ESF systems exposed to treated water is managed at VYNPS by the water chemistry control-BWR program. The effectiveness of the water chemistry control-BWR program will be confirmed by the one-time inspection program through an inspection of a representative sample of components including areas of stagnant flow.2.At VYNPS there are no stainless steel ESF components that are in contact with a soil environment. This item is therefore not applicable to VYNPS.3.Loss of material from pitting and crevice corrosion for BWR stainless steel and aluminum piping and piping components exposed to treated water at VYNPS is managed by the water chemistry control-BWR program. The effectiveness of the water chemistry control-BWR program will be confirmed by the one-time inspection program through an inspection of a representative sample of components including areas of stagnant flow.4.Loss of material from pitting and crevice corrosion could occur for copper alloy and stainless steel piping and components in ESF systems at VYNPS that are exposed to lubricating oil. Loss of material is managed by the oil analysis program, which includes periodic sampling and analysis of lubricating oil to maintain contaminants within acceptable limits, thereby preserving an environment that is not conducive to corrosion. Operating experience at VYNPS has confirmed the effectiveness of this program in maintaining contaminants within limits such that corrosion has not and will not affect the intended functions of these components.5.Loss of material from pitting and crevice corrosion could occur for partially encased stainless steel tanks exposed to raw water due to cracking of the perimeter seal from weathering. At VYNPS there are no outdoor stainless steel tanks in the ESF systems. This item is therefore not applicable to VYNPS.6.Loss of material from pitting and crevice corrosion for BWR stainless steel piping and piping components internally exposed to condensation at VYNPS is managed
| |
| | |
| by the periodic surveillance and preventive maintenance program. This program uses visual and other NDE techniques to manage loss of material for these components.

There are no stainless steel or steel heat exchanger tubes exposed to lubricating oil in the ESF systems. This program includes periodic sampling and analysis of lubricating oil to maintain contaminants within acceptable limits, thereby preserving an environment that is not conducive to fouling. Operating experience at VYNPS has confirmed the effectiveness of this program in maintaining contaminants within limits such that fouling has not and will not affect the intended functions of these components.2.Reduction of heat transfer due to fouling for stainless steel heat exchanger tubes exposed to treated water in ESF systems at VYNPS is managed by the water chemistry control-BWR program. The effectiveness of the water chemistry control-BWR program will be confirmed by the one-time inspection program through an inspection of a representative sample of components crediting this program including areas of stagnant flow.3.2.2.2.5Hardening and Loss of Strength due to Elastomer DegradationAt VYNPS there are no elastomeric components in the ESF systems. This item is not applicable to VYNPS.3.2.2.2.6Loss of Material due to ErosionThis discussion refers to stainless steel high pressure safety injection (HPSI) pump miniflow recirculation orifice exposed to treated borated water. VYNPS is a BWR and has no HPSI pump miniflow orifice and as such this item is not applicable.3.2.2.2.7Loss of Material due to General Corrosion and Fouling.This item refers to loss of material due to general corrosion and fouling occurring for steel drywell and suppression chamber spray system nozzle and flow orifice internal surfaces exposed to air-indoor uncontrolled (internal). At VYNPS the spray nozzles are copper alloy and are not subject to loss of material due to general corrosion in an indoor air environment. There are also no orifices in ECCS systems exposed to an indoor air environment (internal).3.2.2.2.8Loss of Material due to General, Pitting, and Crevice Corrosion1.Loss of material due to general, pitting and crevice corrosion for BWR steel piping and components in ESF systems exposed to treated water is managed at VYNPS by the water chemistry control-BWR program. The effectiveness of the water chemistry control-BWR program will be confirmed by the one-time inspection program through an inspection of a representative sample of components crediting this program including areas of stagnant flow.2.The loss of material due to general, pitting and crevice corrosion for internal surfaces of primary containment penetration steel piping and components Vermont Yankee License Renewal ProjectLRPD-06 Revision 0Page 104 of 488Aging Management Review Summaryexposed to treated water is managed at VYNPS by the water chemistry control-BWR program. The effectiveness of the water chemistry control-BWR program will be confirmed by the one-time inspection program through an inspection of a representative sample of components including areas of stagnant flow.3.Loss of material due to general, pitting and crevice corrosion for steel piping and components in ESF systems exposed to lubricating oil is managed by the oil analysis program. This program includes periodic sampling and analysis of lubricating oil to maintain contaminants within acceptable limits, thereby preserving an environment that is not conducive to corrosion. Operating experience at VYNPS has confirmed the effectiveness of this program in maintaining contaminants within limits such that corrosion has not and will not affect the intended functions of these components.3.2.2.2.9Loss of Material due to General, Pitting, Crevice, and Microbiologically-Influenced Corrosion (MIC)Loss of material due to general, pitting, crevice, and MIC for steel (with or without coating or wrapping) piping and piping components buried in soil in ESF systems at VYNPS is managed by the buried piping inspection program. There are no buried tanks in the ESF systems. The buried piping inspection program will include (a) preventive measures to mitigate corrosion and (b) inspections to manage the effects of corrosion on the pressure-retaining capability of buried carbon steel components. Buried components will be inspected when excavated during maintenance. An inspection will be performed within 10 years of entering the period of extended operation, unless an opportunistic inspection occurred within this ten-year period.3.2.2.2.10Quality Assurance for Aging Management of Nonsafety-Related ComponentsSee Appendix B Section B.0.3 for discussion of VYNPS quality assurance procedures and administrative controls for aging management programs.3.2.2.3Time-Limited Aging AnalysesThe only time-limited aging analysis (TLAA) identified for the ESF systems components is metal fatigue. This is evaluated in Section 4.3.

| Vermont Yankee License Renewal ProjectLRPD-06 Revision 0Page 176 of 488Aging Management Review SummaryThe effectiveness of the water chemistry control-BWR program will be confirmed by the one-time inspection program through an inspection of a representative sample of components crediting this program including areas of stagnant flow.3.3.2.2.3Cracking due to Stress Corrosion Cracking (SCC)1.Cracking due to SCC can occur in the st ainless steel piping, piping components, and piping elements of the BWR standby liquid control (SLC) system that are exposed to sodium pentaborate solution greater than 140°F. At VYNPS the sodium pentaborate solution in the SLC system does not exceed 140°F. Therefore cracking due to SCC is not an aging effect requiring management for the SLC system. This item is not applicable to VYNPS.2.Cracking due to SCC in stainless steel heat exchanger components exposed to treated water greater than 140°F is an aging effect requiring management at VYNPS. There are no auxiliary system components at VYNPS with stainless steel cladding. For VYNPS auxiliary systems these stainless steel heat exchanger components are managed by the water chemistry control-BWR program. This program monitors parameters and contaminants to ensure they remain within the limits specified by the EPRI guidelines. The effectiveness of the water chemistry control-BWR program will be confirmed by the one-time inspection program through an inspection of a representative sample of components crediting this program for managing cracking using visual and ultrasonic inspection techniques.3.Cracking due to SCC in stainless steel diesel engine exhaust piping exposed to diesel exhaust is an aging effect requiring management at VYNPS. At VYNPS cracking of stainless steel exhaust piping in the emergency diesel generator system is managed by the periodic surveillance and preventive maintenance program. This program uses visual and other NDE techniques to manage cracking of the piping. These inspections will manage the aging effect of cracking such that the intended function of the component will not be affected.3.3.2.2.4Cracking due to Stress Corrosion Cracking and Cyclic Loading1.Cracking due to SCC and cyclic loadi ng could occur in stainless steel PWR nonregenerative heat exchanger components exposed to treated borated water greater than 140°F in the chemical and volume control system. VYNPS is a BWR and does not have a nonregenerative heat exchanger exposed to treated borated water. This item is not applicable to VYNPS.2.Cracking due to SCC and cyclic loadi ng could occur in stainless steel PWR regenerative heat exchanger components exposed to treated borated water greater than 140°F. VYNPS is a BWR and does not have a regenerative heat exchanger exposed to treated borated water. This item is not applicable to VYNPS.3.Cracking due to SCC and cyclic loading could occur for the stainless steel pump casing for the PWR high-pressure pumps in the chemical and volume control Vermont Yankee License Renewal ProjectLRPD-06 Revision 0Page 177 of 488Aging Management Review Summarysystem. VYNPS is a BWR and does not have a chemical and volume control system. This item is not applicable to VYNPS.3.3.2.2.5Hardening and Loss of Strength due to Elastomer Degradation1.Cracking and change in material properties due to elastomer degradation in elastomer duct flexible connections of the heating, ventilation and air conditioning systems exposed to air-indoor are aging effects requiring management at VYNPS. These aging effects are managed by the periodic surveillance and preventive maintenance program. This program includes visual inspections and physical manipulation of the flexible connections to confirm that the components are not experiencing any aging that would affect accomplishing their intended functions.2.For the auxiliary systems at VYNPS, no credit is taken for any elastomer linings to prevent loss of material from the underlying carbon steel material such that the material is identified as carbon steel for the aging management review. This item is not applicable to VYNPS.3.3.2.2.6Reduction of Neutron-Absorbing Capacity and Loss of Material due to General CorrosionLoss of material and cracking are aging effects requiring management for Boral spent fuel storage racks exposed to a treated water environment. These aging effects are managed by the water chemistry control - BWR Program.Reduction of neutron-absorbing capacity is insignificant and requires no aging management. The potential for aging effects due to sustained irradiation of Boral was previously evaluated by the staff (BNL-NUREG-25582, dated January 1979; NUREG-1787, VC Summer SER, paragraph 3.5.2.4.2, page 3-408) and determined to be insignificant. Plant operating experience with Boral coupons inspected in 1991 and 1996 is consistent with the staff's conclusion and an aging management program is not required.3.3.2.2.7Loss of Material due to General, Pitting, and Crevice Corrosion1.Steel piping and components in auxiliary systems at VYNPS that are exposed to lubricating oil are managed by the oil analysis program, which includes periodic sampling and analysis of lubricating oil to maintain contaminants within acceptable limits, thereby preserving an environment that is not conducive to corrosion. Operating experience at VYNPS has confirmed the effectiveness of this program in maintaining contaminants within limits such that corrosion has not and will not affect the intended functions of these components.VYNPS is a BWR with an inert containment atmosphere and as a result has no reactor coolant pump oil collection system.2.VYNPS does not have a separate shutdown cooling system. Loss of material due to general, pitting, and crevice corrosion in carbon steel piping and components in Vermont Yankee License Renewal ProjectLRPD-06 Revision 0Page 178 of 488Aging Management Review Summaryother auxiliary systems exposed to treated water are managed by the water chemistry control-BWR program. The effectiveness of the water chemistry control-BWR program will be confirmed by the one-time inspection program through an inspection of a representative sample of components crediting this program including areas of stagnant flow.3.Loss of material due to general (steel only) pitting and crevice corrosion for carbon steel and stainless steel diesel exhaust piping and components exposed to diesel exhaust in the emergency diesel generator and John Deere diesel generator systems is managed by the periodic surveillance and preventive maintenance (PSPM) program. This program uses visual and other NDE techniques to manage loss of material for these components. The carbon steel and stainless steel diesel exhaust piping and components in the fire protection system are managed by the fire protection program. The fire protection program uses visual inspections of diesel exhaust piping and components to manage loss of material. These inspections in the PSPM and fire protection programs will manage the aging effect of loss of material such that the intended function of the components will not be affected.3.3.2.2.8Loss of Material due to General, Pitting, Crevice, and Microbiologically-Influenced Corrosion (MIC)Loss of material due to general, pitting, crevice, and MIC for carbon steel (with or without coating or wrapping) piping and components buried in soil in the service water, fuel oil, and fire protection-water systems at VYNPS is managed by the buried piping inspection program. This program will include (a) preventive measures to mitigate corrosion and (b) inspections to manage the effects of corrosion on the pressure-retaining capability of buried carbon steel components. Buried components will be inspected when excavated during maintenance. An inspection will be performed within 10 years of entering the period of extended operation, unless an opportunistic inspection occurred within this ten-year period. This program will manage the aging effect of loss of material such that the intended function of the components will not be affected.3.3.2.2.9Loss of Material due to General, Pitting, Crevice, Microbiologically-Influenced Corrosion and Fouling1.Fouling is not an aging effect requiring management for the fuel oil system at VYNPS. Loss of material due to general, pitting, crevice, and MIC for carbon steel piping and components exposed to fuel oil is an aging effect requiring management at VYNPS and these components are managed by the diesel fuel monitoring program. This program includes sampling and monitoring of fuel oil quality to ensure they remain within the limits specified by the ASTM standards. Maintaining parameters within limits ensures that significant loss of material will not occur. Ultrasonic inspection of storage tank bottoms where water and contaminants accumulate will be performed to confirm the effectiveness of the diesel fuel monitoring program. In addition, operating experience at VYNPS has confirmed the effectiveness of this program in maintaining fuel oil quality within Vermont Yankee License Renewal ProjectLRPD-06 Revision 0Page 179 of 488Aging Management Review Summarylimits such that loss of material will not affect the intended functions of these components.2.Loss of material due to general, pitting, crevice, MIC and fouling for carbon steel heat exchanger components exposed to lubricating oil are aging effects requiring management in the auxiliary systems at VYNPS, and is managed by the oil analysis program. This program includes periodic sampling and analysis of lubricating oil to maintain contaminants within acceptable limits, thereby preserving an environment that is not conducive to corrosion or fouling. Operating experience at VYNPS has confirmed the effectiveness of this program in maintaining contaminants within limits such that corrosion and fouling has not and will not affect the intended functions of these components.3.3.2.2.10Loss of Material due to Pitting and Crevice Corrosion1.Loss of material due to pitting and crevice corrosion could occur in BWR and PWR steel piping with elastomer lining or stainless steel cladding that are exposed to treated water and treated borated water if the cladding or lining is degraded. For the auxiliary systems at VYNPS no credit is taken for any elastomer linings or stainless steel cladding to prevent loss of material from the underlying carbon steel material such that the material is identified as carbon steel for the aging management review. This item is not applicable to VYNPS.2.In the auxiliary systems at VYNPS there are no aluminum components exposed to treated water. Loss of material due to pitting and crevice corrosion for stainless steel piping and components, and for stainless steel heat exchanger components exposed to treated water in the auxiliary systems at VYNPS is managed by the water chemistry control-BWR program. The effectiveness of the program will be confirmed by the one-time inspection program through an inspection of a representative sample of components crediting this program including susceptible locations such as areas of stagnant flow.3.Loss of material due to pitting and crevice corrosion for copper alloy components exposed to condensation (external) in the HVAC and other auxiliary systems is managed by the system walkdown , periodic surveillance and performance monitoring (PSPM), service water integrity and heat exchanger monitoring programs. The system walkdown program includes a periodic visual inspection. The PSPM, service water integrity and heat exchanger monitoring programs include other NDE techniques to manage loss of material of the components. These inspections will manage the aging effect of loss of material such that the intended function of the components will not be affected.4.Loss of material due to pitting and crevice corrosion for copper alloy components exposed to lubricating oil in auxiliary systems at VYNPS is managed by the oil analysis program which includes periodic sampling and analysis of lubricating oil to maintain contaminants within acceptable limits, thereby preserving an environment that is not conducive to corrosion. Operating experience at VYNPS has confirmed the effectiveness of this program in maintaining contaminants Vermont Yankee License Renewal ProjectLRPD-06 Revision 0Page 180 of 488Aging Management Review Summarywithin limits such that corrosion has not and will not affect the intended functions of these components.5.Loss of material due to pitting and crevice corrosion could occur for HVAC aluminum piping, piping components, and piping elements and stainless steel ducting and components exposed to condensation. At VYNPS there are no aluminum components or stainless steel ducting exposed to condensation in the HVAC systems. However, this item can be applied to stainless steel components exposed to condensation, both internal and external, in other systems. The system walkdown and service water integrity programs will manage loss of material in stainless steel components exposed externally to condensation. The periodic surveillance and preventive maintenance program will manage loss of material in stainless steel components exposed internally or externally to condensation. These programs include a periodic visual inspection and the PSPM program includes other NDE techniques to manage loss of material of the components.6.Loss of material due to pitting and crevice corrosion could occur for copper alloy fire protection system piping, piping components, and piping elements exposed to internal condensation. At VYNPS there are no copper alloy components exposed to condensation in the Fire Protection systems. However, this item can be applied to copper alloy components exposed to internal condensation in other systems. The periodic surveillance and preventive maintenance program will manage loss of material in copper alloy components exposed internally to untreated air, which is equivalent to condensation, through the use of visual inspections or other NDE techniques. The instrument air quality program will manage loss of material in copper alloy components exposed internally to treated air. The instrument air quality program maintains humidity and particulates within acceptable limits, thereby preserving the environment of treated air that is not conducive to corrosion. This is equivalent to the management of loss of material in steel and stainless steel components addressed in Item Numbers 3.3.1-53 and 54 respectively.7.Loss of material due to pitting and crevice corrosion could occur for stainless steel piping, piping components, and piping elements exposed to soil. At VYNPS there are no stainless steel piping components exposed to soil in the auxiliary systems. However, loss of material due to pitting and crevice corrosion for stainless steel bolting buried in soil in the fire protection-water systems at VYNPS is managed by the buried piping inspection program. This program will include (a) preventive measures to mitigate corrosion and (b) inspections to manage the effects of corrosion on the buried stainless steel bolting. Buried components will be inspected when excavated during maintenance. An inspection will be performed within 10 years of entering the period of extended operation, unless an opportunistic inspection occurred within this ten-year period.8.Loss of material due to pitting and crevice corrosion for stainless steel piping and components of the standby liquid control system exposed to sodium pentaborate solution is managed at VYNPS by the water chemistry control-BWR program.

The effectiveness of the program will be confirmed by the one-time inspection program through an inspection of a representative sample of components crediting this program including susceptible locations such as areas of stagnant flow.3.3.2.2.12Loss of Material due to Pitting, Crevice, and Microbiologically-Influenced Corrosion1.Loss of material due to pitting, crevice, and MIC in stainless steel, aluminum and copper alloy piping, and components exposed to fuel oil is an aging effect requiring management at VYNPS and these components are managed by the diesel fuel monitoring program. This program includes sampling and monitoring of fuel oil quality to ensure they remain within the limits specified by the ASTM standards. Maintaining parameters within limits ensures that significant loss of material will not occur. Operating experience at VYNPS has confirmed the effectiveness of this program in maintaining fuel oil quality within limits such that loss of material will not affect the intended functions of these components.2.Loss of material due to pitting, crevice, and MIC in stainless steel piping and components exposed to lubricating oil is managed by the oil analysis program which includes periodic sampling and analysis of lubricating oil to maintain contaminants within acceptable limits, thereby preserving an environment that is not conducive to corrosion. Operating experience at VYNPS has confirmed the effectiveness of this program in maintaining contaminants within limits such that corrosion has not and will not affect the intended functions of these components.3.3.2.2.13Loss of Material due to WearLoss of material due to wear could occur in the elastomer seals and components exposed to air indoor uncontrolled (internal or external). Wear is the removal of surface layers due to relative motion between two surfaces. At VYNPS, in the auxiliary systems, this specific aging effect for elastomers is not applicable based on operating experience. Where the aging effects of change in material properties and cracking are identified for elastomer components, they are managed by the periodic surveillance and preventive maintenance program. This item is not applicable to VYNPS auxiliary systems.

VYNPS is a BWR and has no charging pumps. This item is not applicable to VYNPS.3.3.2.2.15Quality Assurance for Aging Management of Nonsafety-Related ComponentsSee Appendix B Section B.0.3 for discussion of VYNPS quality assurance procedures and administrative controls for aging management programs.3.3.2.3Time-Limited Aging AnalysisThe only TLAA identified for auxiliary system components is metal fatigue. This is evaluated in Section 4.3.3.3.3ConclusionThe auxiliary system components that are subject to aging management review have been identified in accordance with the requirements of 10CFR54.21. The aging management programs selected to manage the effects of aging on auxiliary system components are identified in Section 3.3.2.1 and in the following tables. A description of these aging management programs is provided in Appendix B, along with the demonstration that the identified aging effects will be managed for the period of extended operation.Therefore, based on the demonstrations provided in Appendix B, the effects of aging associated with the auxiliary system components will be managed such that there is reasonable assurance that the intended functions will be maintained consistent with the current licensing basis during the period of extended operation.

| VYNPS License Renewal Project Aging Management Review Summary LRPD-06 Revision 0 Page 214 of 488 305. This treated water or steam environment is from the house heat ing boiler system. The system water is similar to closed cooling water, but monitored by the water chemistry control - aux iliary systems program. 306. This treated water environment does not directly match any NUREG-1801 defined environment. However, for the purposes of evaluating selective leaching, comparison to NUREG-1801 treat ed water or closed cycle cooling water is acceptable since selective leaching is applicable to all water types.

| Vermont Yankee License Renewal ProjectLRPD-06 Revision 0Page 371 of 488Aging Management Review Summary3.4STEAM AND POWER CONVERSION SYSTEMS3.4.1IntroductionThis section provides the results of the aging management review for components in the steam and power conversion systems that are subject to aging management review. These systems are within the scope of license renewal primarily due to their support of the MSIV leakage pathway and components supporting this intended function are grouped in one aging management review. Components in the MSIV leakage pathway are credited with dose reduction under accident conditions for offsite dose and control room habitability considerations. The MSIV leakage pathway starts at the main steam piping at the outlets of the MSIVs and includes the piping and components up to and including the main condenser. The boundary includes the turbine stop valves, turbine bypass valves, and drain lines for the main steam lines. The components included in this aging management review are from various system codes that interface with the main condenser and MSIV leakage pathway: AOG, AS, C, MS, NB, SPL, and 101. The AOG and SPL systems are described in Section 2.3.3.13, Miscellaneous Systems in Scope for (a)(2). The NB system is described in Section 2.3.1, Reactor Coolant System. NB components in main steam line drains are in the MSIV leakage pathway. The remaining systems are described as referenced below.

| Vermont Yankee License Renewal ProjectLRPD-06 Revision 0Page 373 of 488Aging Management Review Summary3.4.2.2.1Cumulative Fatigue DamageWhere identified as an aging effect requiring management, the analysis of fatigue is a TLAA as defined in 10 CFR 54.3. TLAAs are evaluated in accordance with 10 CFR 54.21(c). Evaluation of this TLAA is addressed in Section 4.3.3.4.2.2.2Loss of Material Due to General, Pitting, and Crevice Corrosion1.Loss of material due to general, pitting and crevice corrosion for carbon steel piping and components exposed to treated water or steam is an aging effect requiring management in the steam and power conversion systems at VYNPS, and is managed by the water chemistry control-BWR program. The effectiveness of the water chemistry control-BWR program will be confirmed by the one-time inspection program through an inspection of a representative sample of components crediting this program including susceptible locations such as areas of stagnant flow.At VYNPS there are no tanks or steel heat exchanger components included in the steam and power conversion systems. The condenser is included as part of the main condenser and MSIV leakage pathway but has no aging effects requiring management since their intended function is for holdup and plateout of radioactive materials.2.Loss of material due to general, pitting and crevice corrosion could occur for steel piping and components in steam and power conversion systems exposed to lubricating oil. The steam and power conversion systems at VYNPS have no carbon steel components with intended functions that are exposed to lubricating oil. This item is not applicable to VYNPS.3.4.2.2.3Loss of Material due to General, Pitting, Crevice, and Microbiologically-Influenced Corrosion (MIC), and FoulingLoss of material due to general, pitting, crevice, and MIC, and fouling could occur in steel piping, piping components, and piping elements exposed to raw water. The steam and power conversion systems at VYNPS have no carbon steel components with intended functions that are exposed to raw water. This item is not applicable to VYNPS.3.4.2.2.4Reduction of Heat Transfer due to Fouling1.Reduction of heat transfer due to fouling could occur for stainless steel and copper alloy heat exchanger tubes exposed to treated water. The steam and power conversion systems at VYNPS have no heat exchanger tubes with an intended function of heat transfer and associated aging effect of fouling. However, reduction of heat transfer is managed by the water chemistry control-BWR program for copper alloy heat exchanger tubes in the high pressure coolant injection and reactor core isolation cooling systems. The effectiveness of the water chemistry control-BWR program will be confirmed by the one-time inspection program through an inspection of a representative sample of Vermont Yankee License Renewal ProjectLRPD-06 Revision 0Page 374 of 488Aging Management Review Summarycomponents crediting this program including susceptible locations such as areas of stagnant flow.2.Reduction of heat transfer due to fouling could occur for steel, stainless steel, and copper alloy heat exchanger tubes exposed to lubricating oil.

| Plant-specific notes 401. Aging management of the main condenser is not based on analys is of materials, environments and aging effects. Condenser integrity required to perform the post-accident intended function (holdup and plateout of MSIV leakage) is continuously
| |
| | |
| confirmed by normal plant operation. This intended function does not require the condenser to be leak-tight, and the post-
| |
| | |
| accident conditions in the condenser will be essentially atmospheric. Since normal plant operation assures adequate
| |
| | |
| condenser pressure boundary integrity, the post-accident intended function to provide holdup volume and plateout surface is
| |
| | |
| assured. Based on past precedence (NUREG-1796, Dresden and Quad Cities SER, Section 3.4.2.4.4, and NUREG-1769, Peach Bottom SER, Section 3.4.2.3), the staff concluded that main condenser integrity is continually verified during normal
| |
| | |
| plant operation and no aging management program is required to assure the post-accident intended function.

Section 3.5.2.2 of NUREG-1800 discusses these aging effects th at require further evaluation. The following sections, numbered in accordance with the corresponding discussions in NUREG-1800, explain the VYNPS approach to these areas requiring further evaluation. Programs are described in Appendix B.3.5.2.2.1PWR and BWR Containments3.5.2.2.1.1Aging of Inaccessible Concrete AreasVYNPS has a Mark I free standing steel containment located within the reactor building. Inaccessible and accessible concrete areas are designed in accordance with American Concrete Institute (ACI) specification ACI 318-63, Building Code Requirements for Reinforced Concrete, which results in low permeability and resistance to aggressive chemical solutions by requiring the following.
| |
| *high cement content
| |
| *low water-to-cement ratio
| |
| *proper curing
| |
| *adequate air entrainmentVYNPS concrete also meets requirements of later ACI guide ACI 201.2R-77, Guide to Durable Concrete, since both documents use the same American Society for Testing and Material (ASTM) standards for selection, application and testing of concrete.The below-grade environment is not aggressive (pH > 5.5, chlorides < 500 ppm, and sulfates < 1,500 ppm). Concrete was provided with air content between 3% and 5% and a water/cement ratio between 0.44 and 0.60. Therefore, increase in porosity and Vermont Yankee License Renewal ProjectLRPD-06 Revision 0Page 405 of 488Aging Management Review Summarypermeability, cracking, loss of material (spalling, scaling) due to aggressive chemical attack, and cracking, loss of bond, and loss of material (spalling, scaling) due to corrosion of embedded steel are not applicable for concrete in inaccessible areas. The absence of concrete aging effects is confirmed under the structures monitoring program.3.5.2.2.1.2Crack and Distortion due to Increased Stress Levels from Settlement; Reduction of Foundation Strength, Cracking and Differential Settlement due to Erosion of Porous Concrete Subfoundations, if Not Covered by Structures Monitoring ProgramVYNPS has a Mark I free standing steel containment located within the reactor building and supported by the reactor building foundation. VYNPS does not rely on a dewatering system for control of settlement. Category 1 structures are founded on sound bedrock which prevents significant settlement. Additionally, concrete within five feet of the highest known ground water level is protected by membrane waterproofing. This membrane protects the reactor building concrete against exposure to groundwater. VYNPS was not identified in IN 97-11 as a plant susceptible to erosion of porous concrete subfoundations. Groundwater was not aggressive during plant construction and there is no indication that groundwater chemistry has significantly changed. No changes in groundwater conditions have been observed at VYNPS.As a result cracking and distortion due to increased stress levels from settlement; reduction of foundation strength, cracking and differential settlement due to erosion of porous concrete subfoundations are not applicable to VYNPS concrete structures.3.5.2.2.1.3Reduction of Strength and Modulus of Concrete Structures due to Elevated TemperatureASME Code, Section III, Division 2, Subsection CC indicates that aging due to elevated temperature exposure is not significant as long as concrete general area temperatures do not exceed 150°F and local area temperatures do not exceed 200°F. During normal operation, areas within primary containment are within these temperature limits. Therefore, reduction of strength and modulus of concrete structures due to elevated temperature is not an aging effect requiring management for VYNPS containment concrete.3.5.2.2.1.4Loss of Material due to General, Pitting and Crevice CorrosionVYNPS containment is a Mark I steel containment located within the reactor building. VYNPS reactor building concrete in contact with the drywell shell is designed in accordance with specification ACI 318-63, Building Code Requirements for Reinforced Concrete. The concrete meets requirements of later ACI guide ACI 201.2R-77 since both documents use the same ASTM standards for selection, application and testing of concrete. Concrete is monitored for cracks under the structures monitoring program. The drywell steel shell and the moisture barrier where the drywell shell becomes embedded in the drywell concrete floor are inspected in Vermont Yankee License Renewal ProjectLRPD-06 Revision 0Page 406 of 488Aging Management Review Summaryaccordance with the inservice inspection (IWE) program and structures monitoring program.To prevent corrosion of the lower part of the drywell shell, the interior and exterior surfaces are protected from any contact with the atmosphere by complete concrete encasement. It is not credible for ground water to reach the drywell shell, assuming a crack in the concrete, since the concrete at this location is greater than 8 feet thick and poured in multiple separate horizontal planes. The exterior surface of the drywell shell at the sand cushion interface is effectively drained and protected from consendation or water that might enter the air gap from above. Therefore, significant corrosion of the drywell shell is not expected.3.5.2.2.1.5Loss of Prestress due to Relaxation, Shrinkage, Creep, and Elevated TemperatureVYNPS is a Mark I containment structure and does not incorporate prestress concrete in its design. Therefore, loss of prestress due to relaxation, shrinkage, creep, and elevated temperature is not an applicable aging effect.3.5.2.2.1.6Cumulative Fatigue DamageTLAA are evaluated in accordance with 10CFR 54.21(c) as documented in Section 4 of the application. Fatigue TLAAs for the steel drywell, torus, and associated penetrations are evaluated and documented in Section 4.6.3.5.2.2.1.7Cracking due to Stress Corrosion Cracking (SCC)
| |
| NUREG-1801 recommends further evaluation of inspection methods to detect cracking due to SCC since visual VT-3 examinations may be unable to detect this aging effect. Potentially susceptible components at VYNPS are penetration sleeves and bellows.Stress corrosion cracking becomes significant for stainless steel if tensile stresses and a corrosive environment exist. The stresses may be applied (external) or residual (internal). The normal environment inside the drywell is dry. The penetration components are not exposed to corrosive environments. Therefore, stress corrosion cracking is not an aging effect requiring management for the penetration sleeves and bellows, since the conditions necessary for SCC do not exist.3.5.2.2.1.8Cracking due to Cyclic Loading Cyclic loading can lead to cracking of penetration sleeves, penetration bellows, and torus pool steel. If a CLB analysis does not exist, further evaluation is recommended of inspection methods to detect cracking due to cyclic loading since visual VT-3 examinations may be unable to detect this aging effect. The analysis of cracking due to cyclic loading of the drywell, torus, and associated penetrations is a TLAA which is evaluated as documented in Section 4.6

| Vermont Yankee License Renewal ProjectLRPD-06 Revision 0Page 407 of 488Aging Management Review Summary3.5.2.2.1.9Loss of Material (Scaling, Cracking, and Spalling) due to Freeze-ThawVYNPS has a Mark I free standing steel containment located within the reactor building. Loss of material (scaling, cracking, and spalling) due to freeze-thaw is applicable only to concrete containments. Therefore, loss of material and cracking due to freeze-thaw do not apply.3.5.2.2.1.10Cracking due to Expansion and Reaction with Aggregate, and Increase in Porosity and Permeability due to Leaching of Calcium HydroxideVYNPS has a Mark I free standing steel containment located within the reactor building. In accordance with NUREG-1801, aging management is not required because VYNPS containment concrete (basemat) is designed in accordance with specification ACI 318-63, Building Code Requirements for Reinforced Concrete and concrete specivication requires that the potential reactivity of aggregates be acceptable based on testing in accordance with ASTM C-289 and C-295.3.5.2.2.2Safety Related and Other Structures and Component Supports3.5.2.2.2.1Aging of Structures Not Covered by Structures Monitoring ProgramVYNPS concrete structures subject to aging management review are included in the structures monitoring program. This is true for concrete items even if the aging management review did not identify aging effects requiring management. Aging effects discussed below for structural steel items are also addressed by the structures monitoring program. Additional discussion of specific aging effects follows.1.Cracking, Loss of Bond, and Loss of Material (Spalling, Scaling) Due to Corrosion of Embedded Steel for Groups 1-5, 7, 9 StructuresThe aging mechanisms associated with cracking, loss of bond, and loss of material (spalling, scaling) due to corrosion of embedded steel are applicable only to below-grade concrete/grout structures owing to the slightly acidic pH of groundwater. The below-grade environment for VYNPS is not aggressive and concrete is designed in accordance with specification ACI 318-63, Building Code Requirements for Reinforced Concrete, which results in low permeability and resistance to aggressive chemical solutions by providing a high cement, low water/cement ratio (between 0.44 and 0.60), proper curing and adequate air content between 3 percent and 5 percent. Therefore, cracking, loss of bond, and loss of material (spalling, scaling) due to corrosion of embedded steel are not aging effects requiring management for VYNPS Groups 1-5, 7, 9 structures.2.Increase in Porosity and Permeability, Cracking, Loss of Material (Spalling, Scaling) Due to Aggressive Chemical Attack for Groups 1-5, 7, 9 StructuresAggressive chemical attack becomes significant to concrete exposed to an aggressive environment. Resistance to mild acid attack is enhanced by using a dense concrete with low permeability and a low water-to-cement ratio of less than 0.50. These groups of structures at VYNPS use a dense, low permeable concrete Vermont Yankee License Renewal ProjectLRPD-06 Revision 0Page 408 of 488Aging Management Review Summarywith an average water-to-cement ratio of 0.48, which provides an acceptable degree of protection against aggressive chemical attack. Water chemical analysis results confirm that the site groundwater is considered to be non-aggressive. VYNPS concrete is constructed in accordance with the recommendations in ACI201.2R-77 for durability.VYNPS below-grade environment is not aggressive. Therefore, increase in porosity and permeability, cracking, loss of material (spalling, scaling) due to aggressive chemical attack are not aging effects requiring management for VYNPS Groups 1-5, 7, 9 concrete structures.3.Loss of Material Due to Corrosion for Groups 1-5, 7, 8 StructuresVYNPS structures monitoring program will be used to manage aging effect requiring management for VYNPS Groups 1-5, 7, 8 structures.4.Loss of Material (Spalling, Scaling) and Cracking Due to Freeze-Thaw for Groups 1 3, 5, 7-9 StructuresAggregates were in accordance with specifications and materials conforming to ACI and ASTM standards. VYNPS structures are constructed of a dense, durable mixture of sound coarse aggregate, fine aggregate, cement, water, and admixture. Water/cement ratios are within the limits provided in ACI 318, and air entrainment percentages were within the range prescribed in NUREG-1801. Therefore, loss of material (spalling, scaling) and cracking due to freeze thaw are not aging effects requiring management for VYNPS Groups 1 3, 5, 7-9 structures.5.Cracking Due to Expansion and Reaction with Aggregates for Groups 1-5, 7 9 StructuresAggregates were selected locally and were in accordance with specifications and materials conforming to ACI and ASTM standards at the time of construction, which are in accordance with the recommendations in ACI 201.2R-77 for concrete durability. VYNPS structures are constructed of a dense, durable mixture of sound coarse aggregate, fine aggregate, cement, water, and admixture. Water/cement ratios are within the limits provided in ACI 318, and air entrainment percentages were within the range prescribed in NUREG-1801. Therefore, cracking due to expansion and reaction with aggregates for Groups 1 3, 5, 7-9 structures is not an aging effect requiring management for VYNPS concrete.6.Cracks and Distortion Due to Increased Stress Levels from Settlement for Groups 1-3, 5-9 StructuresVYNPS Class 1 structures are founded on sound bedrock or supported by steel pilings which prevent significant settlement. Therefore, cracks and distortion due to increased stress levels from settlement are not aging effects requiring management for VYNPS Groups 1-3, 5-9 Structures.

| Vermont Yankee License Renewal ProjectLRPD-06 Revision 0Page 409 of 488Aging Management Review Summary7.Reduction in Foundation Strength, Cracking, Differential Settlement Due to Erosion of Porous Concrete Subfoundation for Groups 1-3, 5-9 StructuresVYNPS structures are not constructed of porous concrete. Concrete was provided in accordance with ACI 318 requirements resulting in dense, well-cured, high-strength concrete with low-permeability. Therefore, reduction in foundation strength, cracking, differential settlement due to erosion of porous concrete subfoundation are not aging effects requiring management for VYNPS Groups 1 3, 5 9 structures.8.Lock Up Due to Wear for Lubrite Radial Beam Seats in BWR Drywell and Other Sliding Support SurfacesOwing to the wear-resistant material used, the low frequency (number of times) of movement, and the slow movement between sliding surfaces, lock-up due to wear is not considered to be an aging effect requiring management at VYNPS.
| |
| However, Lubrite plates are included within the structures monitoring program and ISI (IWF) programs to confirm the absence of aging effects requiring management for this component.3.5.2.2.2.2Aging Management of Inaccessible AreasVYNPS concrete for Group 1-3, 5 and 7-9 inaccessible concrete areas was provided in accordance with specification ACI 318-63, Building Code Requirements for Reinforced Concrete, which requires the following, resulting in low permeability and resistance to aggressive chemical solution.
| |
| *high cement content
| |
| *low water permeability
| |
| *proper curing
| |
| *adequate air entrainmentVYNPS concrete also meets requirements of later ACI guide ACI 201.2R-77, Guide to Durable Concrete, since both documents use the same ASTM standards for selection, application and testing of concrete.Inspections of accessible concrete have not revealed degradation related to corrosion of embedded steel. VYNPS below-grade environment is not aggressive (pH > 5.5, chlorides < 500 ppm, and sulfates < 1,500 ppm). Therefore, corrosion of embedded steel is not an aging effect requiring management for VYNPS concrete.3.5.2.2.2.3Reduction of Strength and Modulus of Concrete Structures due to Elevated Temperature Group 1-5 concrete elements do not exceed the temperature limits associated with aging degradation due to elevated temperature. Therefore, reduction of strength and modulus of concrete due to elevated temperatures is not an aging effect requiring management for VYNPS.

Therefore, increase in porosity and permeability, cracking, loss of material (spalling, scaling)/ aggressive chemical attack; and cracking, loss of bond, and loss of material (spalling, scaling)/ corrosion of embedded steel are not an aging effect requiring management for below-grade inaccessible concrete areas of VYNPS Group 6 structures.2.Loss of Material (Spalling, Scaling) and Cracking Due to Freeze-thaw in Below-Grade Inaccessible Concrete Areas of Group 6 StructuresAggregates were selected locally and were in accordance with specifications and materials conforming to ACI and ASTM standards at the time of construction. VYNPS structures are constructed of a dense, durable mixture of sound coarse aggregate, fine aggregate, cement, water, and admixture. Water/cement ratios are within the limits provided in ACI 318, and air entrainment percentages were within the range prescribed in NUREG-1801. Therefore, loss of material (spalling, scaling) and cracking due to freeze thaw are not aging effects requiring management for VYNPS Groups 6 structures below-grade.3.Cracking Due to Stress Corrosion Cracking (SCC), Reaction with Aggregates, Increase in Porosity and Permeability, and Loss of Strength Due to Leaching of Calcium Hydroxide in Below-Grade Inaccessible Concrete Areas of Group 6 Structures Aggregates were selected locally and were in accordance with specifications and materials conforming to ACI and ASTM standards at the time of construction, which are in accordance with the recommendations in ACI 201.2R-77 for concrete durability. VYNPS structures are constructed of a dense, durable mixture of sound coarse aggregate, fine aggregate, cement, water, and admixture. Water/cement ratios are within the limits provided in ACI 318-63, and air entrainment percentages were within the range prescribed in NUREG-1801. VYNPS below-grade environment is not aggressive (pH > 5.5, chlorides < 500 ppm, and sulfates

| < 1,500 ppm).Therefore, cracking due to expansion and reaction with aggregates, increase in pororosity and permeability due to leaching of calcium hydroxide in below grade Vermont Yankee License Renewal ProjectLRPD-06 Revision 0Page 411 of 488Aging Management Review Summaryinaccessible concrete areas of Group 6 structures is not an aging mechanism for VYNPS concrete.3.5.2.2.2.5Cracking due to Stress Corrosion Cracking and Loss of Material due to Pitting and Crevice CorrosionNo tanks with stainless steel liners are included in the structural aging management reviews. Tanks subject to aging management review are evaluated with their respective mechanical systems.3.5.2.2.2.6Aging of Supports Not Covered by Structures Monitoring Program NUREG-1801 does recommends further evaluation of certain component support/aging effect combinations if they are not covered by the applicant's structure monitoring program. Components supports at VYNPS are included in the structures monitoring program for Groups B2 through B5 and inservice inspection (IWF) program for Group B1.(1)Reduction in concrete anchor capacity due to degradation of the surrounding concrete for Groups B1 through B5 supportsVYNPS concrete anchors and surrounding concrete are included in the structures monitoring program (Groups B2 through B5) and inservice inspection (IWF) program (Group B1).

Consistent with the methods described in NEI 95-10, the electrical and I&C aging management reviews focus on commodity groups rather than systems. The following electrical commodity groups requiring aging management review are addressed in this section.
| |
| *insulated cables and connections
| |
| *phase bus*switchyard bus
| |
| *high voltage insulatorsTable3.6.1, Summary of Aging Management Programs for Electrical Components Evaluated in Chapter VI of NUREG-1801, provides the summary of the programs evaluated in NUREG-1801 for the electrical and I&C components. This table uses the format described in the introduction to Section 3. Hyperlinks are provided to the program evaluations in Appendix B.3.6.2ResultsTable3.6.2-1, Electrical and I&C Components - Summary of Aging Management Evaluation, summarizes the results of aging management reviews and the NUREG-1801 comparison for electrical and I&C components.3.6.2.1Materials, Environment, Aging Effects Requiring Management, and Aging Management ProgramsThe following sections list the materials, environments, aging effects requiring management, and aging management programs for electrical and I&C components subject to aging management review. Programs are described in Appendix B. Further details are provided in the system tables.Materials Electrical and I&C components subject to aging management review are constructed of the following materials.

| |
| *reduced insulation resistance (IR)Loss of circuit continuity is listed in NUREG-1801 as an aging effect resulting from corrosion of connector contact surfaces.Aging Management ProgramsThe following programs will manage the effects of aging on electrical and I&C components:
| |
| *non-EQ insulated cables and connections
| |
| *non-EQ instrumentation circuit cables
| |
| *non-EQ inaccessible medium-voltage cables3.6.2.2Further Evaluation of Agi ng Management as Recommended by NUREG-1801NUREG-1801 indicates that further evaluation is necessary for certain aging effects and other issues. Section 3.6.2.2 of NUREG-1800 discusses these aging effects th at require further evaluation. The following sections, numbered corresponding to the discussions in NUREG-1800, explain the VYNPS approach to these areas requiring further evaluation. Programs are described in Appendix B of this application.3.6.2.2.1Electrical Equipment Subject to Environmental QualificationEnvironmental qualification is a TLAA as defined in 10CFR54.3. TLAAs are evaluated in accordance with 10CFR54.21(c). The evaluation of this TLAA is addressed in Section 4.4.3.6.2.2.2Degradation of Insulator Quality due to Presence of Any Salt Deposits and Surface Contamination, and Loss of Material due to Mechanical WearThe discussion in NUREG-1800 concerns effects of these aging mechanisms on high voltage insulators.A high voltage insulator consists of insulating material to support a high voltage conductor and separate the conductor from other conductors and objects. Ceramic and glass porcelain insulators with galvanized hardware are the most common. The insulators evaluated for VYNPS license renewal are those used to support uninsulated, high-voltage electrical components such as transmission conductors and switchyard buses.Various airborne materials such as dust, salt and industrial effluents can contaminate insulator surfaces. The buildup of surface contamination is gradual and in most areas Vermont Yankee License Renewal ProjectLRPD-06 Revision 0Page 479 of 488Aging Management Review Summarywashed away by rain while, the glazed insulator surface aids this contamination removal. A large buildup of contamination enables the conductor voltage to track along the surface more easily and can lead to insulator flashover. Surface contamination can be a problem in areas where there are greater concentrations of airborne particles, such as near facilities that discharge soot or near the seacoast where salt spray is prevalent. VYNPS is not located near the seacoast where salt spray is considered. At VYNPS contamination build-up on insulators is not a concern.
| |
| Therefore, surface contamination is not an applicable aging mechanism for high-voltage insulators at VYNPS.Porcelain is essentially a hardened, opaque glass. As with any glass, if subjected to enough force it will crack or break. The most common cause for cracking or breaking of an insulator is being struck by an object (e.g., a rock or bullet), but cracking and breaking caused by physical damage is not an aging effect and is not subject to AMR. Cracks have occurred with insulators when the cement that binds the parts together expands enough to crack the porcelain. An improper manufacturing process, which makes the cement more susceptible to moisture penetration, causes cement growth. Porcelain cracking caused by cement growth has occurred only in isolated batches of insulators used in strain applications. Utilities replace high voltage insulators in a timely manner, and by tracking dates of manufacturing and manufacturer brands, problem insulators are replaced prior to failure.Cement growth is only an applicable aging mechanism for specific insulators used in strain applications. No such insulators are included in the AMR. Therefore, cracking due to cement growth is not an applicable aging effect for the insulators.Mechanical wear is an aging effect for strain and suspension insulators in that they are subject to movement. Wear has not been apparent during routine inspections. Flashovers from lightning strikes can burn off galvanizing allowing rust to form. If left unmanaged for the period of extended operation surface rust would not cause a loss of intended function and thus is not a significant concern. Loss of material due to wear will not cause a loss of intended function of the insulators. Therefore, loss of material is not an applicable aging effect for insulators.There are no aging effects requiring management for VYNPS high-voltage insulators.3.6.2.2.3Loss of Material due to Wind Induced Abrasion and Fatigue, Loss of Conductor Strength due to Corrosion, and Increased Resistance of Connection due to Oxidation or Loss of Pre-loadTransmission conductors are uninsulated, stranded electrical cables used outside buildings in high voltage applications. The transmission conductor commodity group includes the associated fastening hardware, but excludes the high-voltage insulators.
| |
| Major active equipment assemblies include their associated transmission conductor terminations. Transmission conductors are subject to aging management review if they are necessary for recovery of offsite power following an SBO. At VYNPS, transmission conductors located between switchyard breakers K-1/K-186 and startup transformers Vermont Yankee License Renewal ProjectLRPD-06 Revision 0Page 480 of 488Aging Management Review SummaryT-3-1A/T-3-1B support recovery from an SBO event. Other transmission conductors are not subject to aging management review since they do not perform a license renewal intended function.Switchyard bus is uninsulated, un-enclosed, rigid electrical conductors used in medium and high voltage applications. Switchyard bus includes the hardware used to secure the bus to high-voltage insulators. VYNPS switchyard bus establishes electrical connections to disconnect switches, switchyard breakers, and transformers. Switchyard bus located at the disconnect switches at the Vernon Hydroelectric Station switchyard are necessary for connecting the alternate AC power source from the Vernon dam to essential station switchgear are subject to aging management review. Also, switchyard bus located at the switchyard breakers K-1/K-186 and at startup transformers T-3-1A/T-3-1B that support recovery from an SBO event are subject to aging management review. Other switchyard bus does not require aging management review since they do not perform a license renewal intended function.Connection surface oxidation for aluminum switchyard bus is not applicable since switchyard bus connections requiring AMR are welded connections. For ambient environmental conditions at VYNPS, no aging effects have been identified that could cause a loss of intended function for the period of extended operation. Vibration is not applicable since flexible connectors connect switchyard bus. Therefore, there are no aging effects requiring management for aluminum switchyard bus.3.6.2.2.4Quality Assurance for Aging Management of Nonsafety-Related ComponentsSee Appendix B Section B.0.3 for discussion of VYNPS quality assurance procedures and administrative controls for aging management programs.3.6.2.3Time-Limited Aging AnalysisThe only TLAAs identified for the electrical and I&C commodity components are evaluations for environmental qualification (EQ). The EQ TLAA is evaluated in Section 4.4 of this application.3.6.3ConclusionThe electrical and I&C components that are subject to aging management review have been identified in accordance with the requirements of 10CFR54.21(a)(1). The aging management programs selected to manage aging effects for the electrical and I&C components are identified in Section 3.6.2.1 and in the following tables. A description of aging management programs is provided in Appendix B, along with the demonstration that the identified aging effects will be managed for the period of extended operation.Based on the demonstrations provided in Appendix B, the effects of aging associated with electrical and I&C components will be managed such that there is reasonable assurance the intended functions will be maintained consistent with the current licensing basis during the period of extended operation.
