SECTION 3 AGING MANAGEMENT AGING MANAGEMENT REVIEW RESULTS RESULTS This Section of the safety safety evaluation report (SER) evaluates evaluates aging management management programs programs (AMPs) and aging management management reviews (AMRs) (AMRs) for Beaver Beaver Valley Power Station (BVPS) (BVPS)

Units 1 and 2, by the staff of the United States Nuclear Regulatory Commission (NRC or the the staff). In Appendix B B of its license license renewal application (LRA), FirstEnergy application (LRA), FirstEnergy Nuclear Operating Operating Company (FENOC Company (FENOC or the applicant) described described the 42 AMPs AMPs that itit relies on to managemanage or monitor monitor the aging aging of passive, long-lived structures structures and components (SCs). (SCs).

In LRA Section 3, the applicant provided the results of the AMRs for those SCs applicant provided SOs identified in LRA Section 2, as within the scope of license renewal renewal and subject subject to an AMR.

BVPS Units 1 and 2 are constructed of similar materials with similar environments. Therefore, mechanical system and component the mechanical information presented component information presented in the LRA typically typically applies applies to both units, and no unit-specific identifier is listed. However, design differences unit-specific identifier differences exist between Units 1 and 2. Those design differences differences are identified identified by using a designator (Le., (i.e., Unit 1 only or Unit 2 only). Further, BVPS assigned a different designator (i.e., (Le., common) for those cases in where the system, structure, or component component (SSC) is used used and/or shared shared by both units.

3.0 Applicant's Use of the Generic Aging Aging- Lessons Learned Report Learned Report In preparing its LRA, the applicant applicant credited NUREG-1801, NUREG-1 801, Revision 1, "Generic Aging Lessons Lessons Learned (GALL)

(GALL) Report," dated September dated September 2005. The GALL GALL Report contains the staff's generic generic evaluation of the existing plant programs evaluation programs and documents documents the technical basis for determining determining where existing programs are adequate existing programs adequate without modification, modification, and where existing programs programs augmented for the period of extended operation.

should be augmented operation. The evaluation results documented in the GALL Report indicate that many of the existing programs GALL Report programs are adequate to manage manage the the aging effects effects for particular license license renewal SCs. The GALL Report Report also contains contains recommendations on specific areas for which existing programs recommendations programs should be augmentedaugmented for for license license renewal. An applicant may reference reference the GALL Report Report in its LRA to demonstrate demonstrate that its programs correspond programs correspond to those reviewed and approved approved in the report.

The purpose of the GALL Report is to provide a summary of staff-approved staff-approved AMPs to manage manage or monitor the aging aging of SCs SOs subject to an AMR. If If an applicant commits commits to implementing implementing these these staff-approved staff-approved AMPs, the time, effort, and resources for LRA review will be greatly reduced, improving the efficiency efficiency and effectiveness effectiveness of the license renewal review process. The GALL Report also serves serves as a quick reference for applicants reference applicants and staff reviewers reviewers to AMPs and determined will adequately manage activities that the staff has determined manage or monitor aging during the the period of extended extended operation.

To determine whether use of the GALL Report would improve improve the efficiency of LRA review, review, the the conducted a demonstration staff conducted demonstration of of the the GALL Report Report process process in order to to model the format and evaluations based on content of safety evaluations on it.

it. The results results of the demonstration demonstration project confirmed GALL Report process will improve the efficiency that the GALL efficiency and effectiveness effectiveness of LRA review review while while maintaining the staff's focus on public health and safety. NUREG-1800, maintaining NUREG-1800, Revision 1, "Standard"Standard Review Plan for Review of License Renewal Applications for Nuclear Power Plants" Review Plants" (SRP-LR),

dated September 2005, was prepared based on both the GALL Report model and lessons lessons learned from the demonstration learned demonstration project.

staff 's review was in The staff's in accordance accordance with Title 10, Part 54, of the Code of Federal FederalRegulations Regulations (10 CFR Part 54), "Requirements for Renewal of Operating Licenses for Nuclear Power Plants,"

(10 and the guidance guidance of the SRP-LR and the GALL Report.

In addition to its review of the LRA, the staff conducted an onsite audit of associated associated AMPs, during the week of March March 3-7, 2008. The onsite audits and reviews are designed for maximum maximum efficiency staff s LRA review. The applicant can respond to questions, the staff can readily efficiency of the staff's evaluate evaluate the applicant's responses, the need for formal correspondence correspondence between the staff and the applicant is reduced, and the result is an improvement in review efficiency.

3.0.1 Format of the License Renewal Renewal Application The applicant applicant submitted an application that follows the standard LRAformat LRA format agreed to by the the staff and the Nuclear Energy Institute (NEI) (NEI) by letter dated April 7, 2003. This revised LRA format incorporates incorporates lessons learned from the staff's reviews of the previous five LRAs, which used aa format developed developed from information gained staff-NEI demonstration gained during a staff-NEI demonstration project conducted conducted to evaluate the use of the GALL Report in the LRA review LRA review process.

The organization organization of LRA Section 3 parallels parallels that of SRP-LR SRP-LR Chapter Chapter 3. LRA Section Section 3 presents presents AMR results information in the followingfollowing two table types:

(1) Table 1s: ls: Table 3.x.1 -where

-where "3" indicates the LRA Section number, "x" indicates the the subsection subsection number from the GALL Report, and "1" "1" indicates indicates that this table type is thethe first in LRA Section 3.

(2)

(2) Table Table 2s: Table 3.x.2-y - where "3" indicates indicates the LRA Section Section number, "x" indicates indicates the the subsection subsection number from the GALL Report, "2" indicates that this table type is the second in LRA LRA Section 3, and "y" indicates indicates the system table number.

The content content of the previous previous LRAs LRAs and application is essentially and of the BVPS application essentially the same. TheThe intent intent of the revised format of the LRA for BVPS was to modify the tables in LRA Section 3 to provide additional provide additional information that would assist in the staff's review. In its Table Table 1s, 1s, the applicant applicant summarized summarized the portions of the application application that it considered to be consistent with the GALL Report. In In its Table Table 2s, the applicant identified identified the linkage between between the scoping scoping and screening results results in LRA LRA Section 2 and the the AMRs in LRA Section Section 3.

3.0.1.1 3.0.1.1 Overview of Table 1s Is Each Each Table 1 compares compares in summary summary how how the facility aligns aligns with the corresponding corresponding tables tables in the the GALL GALL Report. The tables tables are are essentially essentially thethe same same as Tables Tables 1 through through 66 in the GALL GALL Report, 3-2 3-2

"Discussion" information. The following are examples of information that might be contained within this column:

" evaluation recommended further evaluation recommended - information or reference reference to where that information is located

  • plant-specific program The name of a plant-specific
    • exceptions to GALL Report assumptions exceptions assumptions
  • discussion of how the line is is consistent with the corresponding corresponding line item in the GALL Report when the consistency consistency may not not be obvious obvious
  • discussion of how the item is different different from the corresponding line item in the GALL Report (e.g., when an exception exception is taken to a GALL Report AMP)

The format of each Table 1 allows the staff to align a specific row in the table with the the corresponding corresponding GALL Report table row so that the consistency can be checked checked easily.

Overview of Table 3.0.1.2 Overview Table 2s Each Table 2 provides the detailed results of the AMRs for components identified identified in LRA Section 2 as subject to an AMR. The LRA has a Table 2 for each of the systems or structures structures within a specific system grouping (e.g., (e.g., reactor coolant coolant system system (RCS), engineered engineered safety features (ESF), auxiliary auxiliary systems, etc.). For example, the ESF group group has tables specific to the the containment spray system, containment isolation system, and emergency emergency core cooling system. system.

Each Table 2 consists of nine columns:

Component Type - The first column lists LRA Section 2 component types subject to an Component Type - The first column lists LRA Section 2 component types subject to an AMR in alphabetical order.

    • Intended Function - The second column identifies the license renewal intended functions, including including abbreviations, abbreviations, where applicable, applicable, for the listed component component types.

Definitions and and abbreviations abbreviations of intended functions are in LRA Table 2.0-1. 2.0-1.

Any plant-specific identified by numbers plant-specific notes identified numbers provide additional information information about about the consistency consistency of the line item with the GALL Report.

3.0.2 Staff's 3.0.2 Staffs Review ProcessProcess The staff conducted evaluations of the AMRs and AMPs:

conducted three types of evaluations (1) For items that the applicant has stated were consistent with the GALL Report, the staff staff conducted conducted either an audit or a technical review to determine determine consistency.

(2) For items that the applicant has stated were consistent with the GALL Report with with exceptions, enhancements, or both, the staff conducted exceptions, enhancements, conducted either an audit or aa technical review of the item to determine consistency. In addition, the staff conducted either an audit or a technical review of the applicant's applicant's technical justifications for the exceptions technical justifications exceptions or the adequacy of the enhancements.

enhancements.

The SRP-LR SRP-LR states that an applicant applicant may take one or more more exceptions to specific GALL AMP elements; however, any deviation from or exception exception to the GALL AMP should be be described described and justified. Therefore, the staff considers considers exceptions exceptions as being portions of the the GALL AMP that the applicantapplicant does not intend to implement.

In some cases, an applicant applicant may choose an existing plant program program that does not meet all the program elements defined elements defined in the GALL AMP. However, the applicant applicant may make a commitment commitment to augmentaugment the existing program to satisfy the GALL AMP prior to the the period extended operation.

Enhancements include, but are not limited to, activities enhancements. Enhancements activities needed needed to ensure consistency with the GALL Report recommendations. Enhancements Report recommendations. Enhancements may expand, but not reduce, the scope of an AMP.

(3) For other items, the staff conducted conducted aa technical technical review review to verify conformance conformance with 10 CFR 54.21(a)(3) 54.21(a)(3) requirements.

Staff audits and technical technical reviews of the applicant's applicant's AMPs and AMRs determine determine whether the the aging effects on SCs can be adequately adequately managed managed to maintain maintain their intended function(s) consistent with the plant's CLB for the period of extended consistent extended operation, as required by 10 CFR Part 54.

Staff Evaluation.

Evaluation. In the LRA, the applicant applicant stated stated that the Bolting Integrity Program .is is an existing existing program program that is consistent with GALL GALL AMP XI.M18.XI.M1B.

During its audit, the staff reviewed reviewed the applicant's onsite documentation documentation to support support its conclusion conclusion that the program program elements are consistent with the elements in the GALL Report. The staff staff interviewed interviewed the applicant's applicant's technical technical staff and reviewed onsite documents.

In comparing the 10 program elements in the applicant's program program to GALL AMP XI.M18, XI.M1B, the the staff found that the GALL GALL Report "monitoring and trending" program program element, requiring that the the leak rate be monitored on a defineddefined schedule, properly documented schedule, was not properly documented in the applicant's applicant's program.

bolting integrity program.

In RAI B.2.6-2, dated MarchMarch 26, 2008, 200B, the staff requested that the applicant provide additional applicant provide information information on its leak rate monitoring schedule.

In its response to RAI B.2.6.-2, dated April 25, 200B, 2008, the applicant stated that leaks related to to bolting, not covered by ASME ASME Section XI, are monitored monitored and corrected corrected using the FENOCFENOC Corrective Corrective Action Program. The applicant further further stated that itit relies upon this corrective action action program to determine determine the inspection frequency frequency and required response response in order to adequately adequately address the leak. However, the staff noted that the FENOC Corrective Corrective Action Program has no no specific requirements, checks, or limiting processesprocesses which would ensure that the inspection inspection frequency frequency does not decrease decrease to less than the biweekly recommendation in the GALL biweekly recommendation GALL Report.

Therefore, the staff determined that the applicant did not provide sufficient information to to address address the concerns raised in the staff's RAI B.2.6-2, and finds that the program is not consistent consistent with the GALLGALL Report "monitoring and trending" program element. The staff further determined determined that, pursuant to the guidance guidance in SRP-LR Section 3.1.2.1, 3.1.2.1, this inconsistency inconsistency shall documented as a staff-identified be documented staff-identified difference.

As described described above, the staff noted a difference difference in the Bolting Integrity Program that the the applicant identified as an exception to the GALL AMP XI.M1B.

By letter dated October October 10,10, 2008, the applicant applicant provided provided additional justification justification for the staff- .

identified difference identified difference resulting from its previous response to RAI B.2.6-2. The applicant applicant stated that although although itit has no specific written guidance guidance that requires daily monitoring of identified identified leaks leaks in non-ASME non-ASME boltedbolted connections, leaks are managed by one of several several plant programs, each each of which classifies and assesses assesses the significance ofthe of the leakage. The applicant applicant also stated that in addition addition to the FENOC FENOC Corrective Action Program Program which manages manages leaks leaks that are classified as being "conditions adverse adverse to quality" through periodic monitoring and trending, itit also utilizes the the Leak Elimination Elimination Program. The applicant identifies daily rounds and walk-downs walk-downs performed by by operators, operators, maintenance, maintenance, and system engineersengineers as contributing contributing to the identification identification and monitoring of leaks.

Additionally, the applicant stated that leak repair prioritization determined through the Work prioritization is determined Management Process for Units 1 and 2, in accordance Management accordance with Institute for Nuclear Power Nuclear Power Operations (INPO)

(INPO) AP-928, "Work Management Management ProcessProcess Description," which which prioritizes prioritizes leak repairs based on work classification and significance significance (i.e.,

significance).

Furthermore, the applicant applicant stated that the Leak Elimination Elimination Program for Units 1 and 2, performs performs monitoring and trending trending to ensure ensure that leaks which are not considered considered a "condition adverse adverse to quality" do not challenge challenge system or component functions.

supplement to its original response The staff reviewed the applicant's supplement response to RAI B.2.6-2, and determines that proper plant programsprograms are in place that address leakage of non-ASME address leakage non-ASME bolted bolted connections through the implementation implementation of monitoring, monitoring, trending, classification, classification, and prioritization prioritization processes. The clarification clarification helped helped the staff determine that the applicant's leakage leakage monitoring monitoring for non-ASME bolted connections demonstrates proper management connections demonstrates management of leakageleakage through robust programs which plant programs which meet the intent of the GALL Report "monitoring and trending" program program element. Based on its review, the staff finds the applicant's response to RAI B.2.6-2 acceptable B.2.6-2 acceptable and this staff-identified staff-identified difference difference to be acceptable. Therefore, Therefore, the staff's concern described described in RAI RAI B.2.6-2 is resolved.

In the LRA, the applicant applicant stated that loss of preload is not an AERM. AERM. The staff requested that that the applicant applicant justify its position in not managing managing the aging effect effect for loss of preload preload in RAI B.2.6-3, by letter dated May 8, 2008.

By letter dated dated June 9, 2008, the applicant applicant responded responded to RAI B.2.6-3, stating that it manages manages loss of preload through leakage monitoring leakage monitoring and proper installation and maintenance maintenance of the the components, since the loss of preload in a mechanical joint can result in leakage. The applicant applicant references Electric references Electric Power Research Research Institute (EPRI)

(EPRI) Report 10106039 which offers guidance on Report 10106039 loss of preload for bolted closures. The guidance guidance states that loss of preload preload in a mechanical joint does not result in failure of that joint.

The staff finds that the the "scope of program" program element for the applicant's Boric Acid Corrosion "scope of program" program element for the applicant's Program acceptable acceptable because itit conforms conforms to the recommended recommended GALL AMP XLM10 XI.M10 and because because thethe applicant applicant has conservatively included copper alloy componentscomponents within the scope of the program.

The staff also noted that the applicant's Boric Acid Corrosion Corrosion Program was established based on the applicant's applicant's response to Generic Letter (GL) (GL) 88-05, "Boric Acid Corrosion of Carbon Steel Reactor Pressure Boundary Reactor Boundary Components Components in PWR Plants." The staff finds this to be acceptableacceptable because itit is in conformance because conformance with GALL AMP XI.M10. XLM10.

The staff also noted noted that the Boric Acid Corrosion Program Program includes provisions for engineering engineering evaluations and corrective corrective actions, and that if the applicant detects detects any evidence of borated water leakage, either by programmatic programmatic inspections or by other activities, the leakageleakage is evaluated evaluated and resolved using the FENOC Corrective Corrective Action Program. The staff also noted that the boric acid leakage leakage inspections inspections are performed, performed, pursuant pursuant to the AMP, by qualified qualified boric acid acid corrosion control inspectors. As part of their training, these inspectors complete a VT-2 general corrosion training course course and perform the VT-2 visual examinations accordance with either examinations in accordance either direct visual examination methods or by remote visual examination examination examination techniques. The staff further noted noted that the FENOC Corrective Corrective Action Program requires that the applicant applicant document document its results from system walkdowns and VT-2 visual examinations examinations on a Boric Acid Corrosion Corrosion Control Leakage Control Leakage Inspection Report Form, which is retained on file.

The staff determined determined that these aspects aspects of the applicant's applicant's program were consistent with the the recommended recommended criteria provided in the program elements elements of GALL AMP XLM1 XI.M10.o. Based on thisthis review, the staff concludes concludes that, in addition to the "scope of program" program element, the programllprogram the remaining remaining program elements for the Boric Acid Corrosion Program are acceptable acceptable because they are consistent with the staff's corresponding corre~ponding program program element criteria criteria recommended in GALL AMP XLM10.

In its response to RAI B.2. B.2.7-1, 7-1, dated July 24, 2008, the applicant stated that it does not credit this program for management management of cracking in nickel-alloy components, including those in ASME ASME Code Class 1 systems. The applicant stated that, instead, management management of cracking cracking in in nickel-alloy components, including ASME Code Class 1 nickel'-alloy nickel-alloy nickel-alloy components, components, is accomplished through accomplished implementation of one or more through implementation more of the following AMPs:

  • B.2.2 ASME Section XI Xl Inservice Inservice Inspection, Subsections IWB, IWC, and IWD Inspection, Subsections IWD

  • B.2.42 Water Chemistry Components made from nickel-alloy alloy base metals and nickel-alloy welds are not wastage induced by boric acid leakage in the manner that steel components susceptible to wastage components (i.e.,

carbon steels, alloy steels, or cast irons) or aluminum componentscomponents are. Thus, the staff noted that the applicant's comment comment that nickel-alloy nickel-alloy components are not within the scope of the Boric Boric Acid Corrosion Program was valid because because it was consistent consistent with this technical basis and with the scoping assessment assessment in the "scope of program" program element in GALL AMP XI.M10. XI.M1 O. The The staff noted noted however, that leakageleakage from nickel-alloy nickel-alloy components potentially potentially could be sources sources of of borated water borated leakage for steel, copper alloy, or aluminum water leakage aluminum alloy components within the vicinity nickel-alloy components. Thus, the staff was of the opinion that steel, copper of these nickel-alloy copper alloy, and aluminum alloy components within the vicinity vicinity of nickel-alloy nickel-alloy components in systems containing systems containing borated water inventories borated inventories must be included within the scope of the applicant's applicant's Boric Acid Corrosion Control Program.

To address this, the staff reviewed reviewed the applicant's applicant's Type 2 AMR Tables in the LRA for BVPS to determine whether the applicant does credit the Boric Acid Corrosion Program for management determine management of loss of material due boric acid leakage in the surfaces surfaces of steel, aluminum alloy and copper alloy components components that are in vicinity of borated systems containing nickel-alloy component nickel-alloy component locations. The staff verified that the applicant does does credit the Boric Acid Corrosion Program Program to manage loss of material manage material due to boric acid leakage leakage in steel, copper alloy, and aluminum aluminum alloy alloy component surfaces that could be potentially exposed component exposed to leakage leakage from borated systems, including those in the vicinity of nickel-alloy including nickel-alloy component component locations locations or nickel-alloy welds. The staff staff also verified verified that this includes steel, aluminum alloy, and copper alloy componentscomponents in the RV, reactor coolant pressure pressure boundary boundary (RCPB) piping, pressurizer, SG, safety injection, injection, residual (RHR), containment heat removal (RHR), containment spray, chemical and volume control, boron recovery recovery and primary grade water, area area ventilation ventilation - other, and building and yard drain systems. Thus, the the staff found that the applicant applicant has updated its program to address the impacts impacts of borated water leakage that potentially potentially could occur from through-wall through-wall cracking in nickel-alloy nickel-alloy components components in borated systems systems and, therefore, as updated the program address address relevant operating experience experience from nickel-alloy nickel-alloy component locations. Thus, the staff finds that the applicant's applicant's Boric Acid Acid Corrosion Program Program has accounted for applicable applicable operating experience experience associated associated with borated water leakage, including operating operating experience associated with boratedborated water leakage that has has occurred occurred from nickel-alloy nickel-alloy components.

Based on this review, the staff concludes concludes that the applicant has demonstrated demonstrated that its Boric AcidAcid Corrosion Program is capablecapable of identifying, identifying, monitoring, monitoring, and correcting the effects of boric acidacid corrosion corrosion on the intended intended function of steel, copper alloy, and aluminum alloy components that may be exposed to borated borated water leakage, because the staff has verified that the program is consistent consistent with the recommendations recommendations in GALL GALL AMP XI.M1 0 and in SRP-LR SRP-LR Section A.1.2.3.10 A.1.2.3.1 0 and that the program program is updated to account account for relevant operating operating experience. this Based on this determination, determination, the staff concludes concludes that the Boric Acid Corrosion Corrosion Program Program can be expected expected toto ensure that the systems systems and components components within the scope of this program continue to program will continue perform perform their intended intended functions functions consistent with the CLB for the period extended operation.

B.2.30-1, dated In RAI B.2.30-1, dated April 30, 2008, the staff requested requested that the applicant respond to the the following staff concerns: (a) explain explain how the applicant manages the effects of aging beyond applicant manages the beyond the volumetric inspection that is conducted prior to the period of extended volumetric inspection extended operation; (b) describe describe the types of materials used to construct construct the aboveground aboveground tanks located located outside; and (c) discuss discuss the applicant's applicant's operating history with aboveground aboveground tanks.

In its response to RAI B.2.30-1, B.2.30-1, dated May 5,2008, 5, 2008, the applicant stated:

The inspection of the tank bottom prior to entering the period of extended operation operation is the only part of the AMP assigned to manage the potential for aging aging of the external external bottom surfaces surfaces of tanks mounted on concrete concrete foundations at BVPS.

BVPS has five aboveground tanks within the scope of license renewal renewal that are located outside and mounted located outside mounted on on concrete concrete foundations. These tanks are summarized summarized in the following table:

3-25

Tank name Material Material of Construction Refueling Water Refueling Water Storage Storage Tank Tank steel Stainless steel Refueling Water Refueling Water Storage Storage Tank Stainless steel steel Demineralized Water Turbine Plant Demineralized Aluminum Storage Tank Demineralized Water Storage Demineralized Storage Tank Stainless steel Stainless Demineralized Water Storage Tank Stainless steel Stainless includes one or more of the following design or construction Each of these tanks includes construction bitumastic coating, sloped foundations, caulking, features: an oil-sand bed, bitumastic and/or sealing fillets. These features are expected to preclude preclude water from the the bottom surfaces of the tanks that could result result in aging effects. In In the BVPS BVPS License Renewal Renewal Application, FENOC credits either the External Surfaces Surfaces Monitoring Program or the Structures Monitoring; Program Program for managing the the observable construction aging of the externally observable construction features (sloped foundations, caulking, and sealing fillets). However, since verification verification of the absence of water on the bottom surfaces surfaces of the tanks is impractical, these tanks are evaluated using the environment environment of "soil" for the external external bottom surfaces. "Soil" was was determined to approximate approximate the worst conditions that could exist if if water were not not excluded. Loss of material was identified as a potential potential aging effect for the the bottom surfaces of these tanks if if the design and construction construction features failed to exclude water. The One-Time Inspection Program was assigned to verify that the the aging effect is not occurring; should the aging effect be verified to be present, the the program additional actions that assure the intended function of the tanks program triggers additional will be maintained maintained during the period of extendedextended operation. No additional program program was assigned to manage the external bottom surfaces of the tanks, as as the aging effect is expected expected to be precluded precluded by design design and construction construction features, and the purpose purpose of the One-Time Inspection Inspection Program is to verify the absence of such effects.

The same aging management management approach approach was used to address aging of the the surfaces of the enclosure-protected external bottom surfaces enclosure-protected Primary Plant Demineralized Demineralized Water (Storage) Tanks at both units. The Unit 1 tank is fabricated fabricated of steel, and the Unit 2 tank is fabricated fabricated of stainless steel. Both tanks are mounted on on concrete foundations concrete foundations with design and construction construction features to preclude preclude the the presence presence of water water from the tank bottom bottom surfaces. Additionally, these tanks tanks are located located within reinforced reinforced concrete concrete structures structures that provide additional additional protection protection from the outside environment.

The staff confirms that stainless steel and aluminum tanks do not require coating of the the external surfaces, which is, as the applicant applicant points out, a major part of the Aboveground Aboveground Tanks Aboveground Tanks Program Program. Both the Aboveground Program and the One-Time Inspection Program require One-Time Inspection inspection of the tank bottoms, and because one-time inspection a one-time external coatings are not an issue because the external issue for these tanks, the staff finds that One-Time Inspection Program for checking tank bottoms is One-Time Inspection is acceptable. Therefore, the staff's concerns concerns described described in in RAI B.2.30-1 B.2.30-1 are resolved.

The staff confirmed confirmed that the operating experience program element satisfies the criterion operating experience criterion defined in defined in the GALL GALL Report Report and inin SRP-LR Section A. 1.2.3.10.

Underlying Underlying Assumptions:

Assumptions: EO EQ component component aging evaluations contain sufficient sufficient conservatism conservatism to account for most environmental changes environmental changes occurring due to plant modifications and events. When unexpected modifications unexpected adverseadverse conditions are identified identified during operational or maintenance maintenance activities that affect affect the normal operating environment of a qualified environment qualified component, component, the affected EO EQ component is evaluated and appropriate corrective actions are taken, which may include changes to the appropriate corrective the qualification bases qualification bases and conclusions. Excess conservatism Excess conservatism in thermal life analysis analysis may be reduced reduced by reevaluating material material activation activation energy, to justify a higherhigher value that value that would would support extended extended life at elevated temperature. Similar methods methods of reducing excess conservatism in the component component service conditions and material properties material properties used in prior aging evaluations evaluations may be used for radiation and cyclical aging. Any changes to material activation activation energy will be justified.

Acceptance Acceptance Criteria Criteria and Corrective Corrective Actions: If If qualification qualification cannot be extended by reanalysis, the component is refurbished or replaced prior to exceeding the the period for which the current qualification qualification remains valid.

Based on its review, the staff finds the applicant's applicant's response to RAI B.2.14-1 acceptable acceptable because because the applicant has amended amended the LRA such that the Environmental Environmental Qualification Qualification (EQ)

(EQ) of Electric Electric Components ProgramProgram now contains the reanalysis attributes. These attributes are consistent consistent with those described in GALL GALL AMP X.EI. X.E1. Therefore, Therefore, the staffs concern described in concern described RAI B.2.14-1 is resolved.

The applicant stated in its basis documents documents that the Detection Detection of Aging Affects and Monitoring Monitoring and Trending program program sub-element sub-element is consistent consistent with that of GALL AMP X.E1 and was was addressed in basis document document references.

references. However, the staff reviewed these references references and found that they did not specifically specifically address address monitoring or inspection inspection of certain environments environments to to ensure that a component component is within the boundsbounds of its qualification basis, or as aa means to modify qualified life.

the qualified In RAI B.2.14-2, dated May 15, 2008, the staff requested requested that the applicant address address how it performs or inspects certain environments to ensure certain environments ensure that a component component is within the bounds bounds of its qualification basis or aa means to modify the qualified qualified life during the extended extended period of operation. The staff also requested requested the applicant applicant revise the plant procedure procedure to address this this element.

In its response to RAI B.2.14-2, dated June 17, 2008, the applicant applicant stated that 10 CFR 50.49, "Environmental Qualification of Electric Equipment "Environmental Equipment Important to Safety for Nuclear Power Plants," and GALL AMP X.E1, X.E1, do not require detection, monitoring or trending detection, monitoring trending of aging effects effects of in-service in-service components. GALL AMP X.E1, X.E1, elements 4 and 5 state:

4. Detection of Aging Effects: 10 CFR 50.49 does not require the detection Detection detection of aging effects for in-service Monitoring or inspection of certain in-service components. Monitoring environmental conditions or component parameters environmental parameters may be used to ensure ensure that the component component is within the bounds of its qualification qualification basis, or as a means to modify the qualified life.
5. Monitoring Monitoring and Trending:

Trending: 10 CFR 50.49 does not require monitoring and trending of component component condition or performance performance parameters parameters of in-service in-service components to manage components manage the effects of aging. EQ program actions that could be viewed viewed as monitoring monitoring include monitoring how long qualified components components have been installed. Monitoring installed. Monitoring or inspection inspection of certain environmental, environmental, condition, or component parameters parameters may be used to ensure that a component is within the bounds of its qualification qualification basis, or as a means means to modify the qualification.

applicant also stated that while The applicant while the the BVPS BVPS Environmental Qualification (EQ) of Electrical Electrical Components Program Components Program doesdoes not require monitoring monitoring and trending of component condition condition or performance parameters of in-service components to manage the effects of aging, the program procedure does provide for inspections and monitoring activities, which are acceptable bases to ensure that the component is within the bounds of its its qualification qualification basis or to modify the qualified life through reanalysis. Specifically the EQ Program Program procedure requires that: that:

  • " Engineer determine The EQ Engineer determine the established qualified life values by by developing and verifying an aging analysis for establishingestablishing the replacement cycle for electrical equipment replacement equipment and/or associated associated parts.
    • Based on the results of the aging analysis,analysis, the EQ Engineer Engineer designate designate the equipment and part service life values that shall be utilized in in determining the replacement replacement period.
    • Engineer prepare aa Maintenance The EQ Engineer Maintenance Assessment Package Package identifying specific maintenance identifying maintenance requirements requirements to preserve qualification, replacement intervals based on verified qualified replacement qualified life values, and any interface requirements, and maintenance surveillances (such as interface as temperature temperature or radiation monitoring) necessary monitoring) necessary to monitor certain equipment parts that are likely to experience age-related age-related degradation.
  • " FENOC implement the maintenance maintenance surveillances necessarynecessary to monitor certain equipment equipment parts that are likely to experience experience age-related age-related degradation.

The applicant further stated that the BVPS EQ procedure procedure is compliant with the requirements requirements of 10 CFR 50.49. GALL AMP X.E1 X.E1 program program sub-elements sub-elements do not require monitoring monitoring or inspecting inspecting certain environments environments ensure to ensure that a component component is within the bounds of its qualification qualification basis, or as aa means to modify modify the qualified qualified life. Therefore, Therefore, no changes required for the BVPS EQ changes are required EQ program.

Because GALL AMP X.E1 program Because program elements elements do not require monitoring and trending require monitoring trending of component condition component condition or performance parameters of in-service performance parameters in-service components components to manage manage the the effects of effects aging,aging, the staff determines determines that the BVPS Environmental Qualification Environmental Qualification (EQ) of(EQ) of Electrical Components Program, Electrical Program, which which is consistent with GALL X.E1, are not GALL X.E1, not required to be be changed.

Based on its review, the staff finds the applicant response to RAI B.2.21-2 B.2.21-2 acceptable acceptable because because confirmed the use of technical applicant has confirmed the applicant guidance of the staff and technical information and guidance industry guidance documents industry guidance documents to develop Inaccessible Medium-Voltage develop the Inaccessible Medium-Voltage Cables Not Subject 10 CFR 50.49 Environmental to 10 Environmental Qualification Qualification Requirements Program. The staff notes that the Requirements Program. the applicant applicant has listed these documents documents in its program evaluation program evaluation document. Therefore, the staff's staff's concern described in RAI B.2.21-2 concern described B.2.21-2 is resolved.

Operating Experience. The staff reviewed the operating Operating operating experience experience reports, including including a sample sample of condition reports, and interviewed interviewed the applicant's applicant's technical staff to confirm that the plant-experience did not reveal any degradation specific operating experience degradation not bounded by industry experience. LRA Section B.2.21 states that the inaccessible inaccessible medium-voltage medium-voltage cables is a new program for which there is not plant-specific plant-specific operating experience experience for program effectiveness.

Industry and plant-specific Industry plant-specific operating operating experience experience will be evaluated in the development development and implementation implementation of this program. GALL AMP XI.E3 states states that operating experience experience has shown that cross linked linked polyethylene polyethylene or high molecular molecular weight polyethylene polyethylene insulation materials are insulation materials most susceptible susceptible to waterwater tree formation. The formationformation and growth growth of water trees varies directly directly with operating voltage. Also, minimizingminimizing exposure exposure to moisture moisture minimizes the potential for the the development of water development water treeing.

In LRA Section B.2.21, the applicant Section B.2.21, applicant also states that currently it has a manhole inspection program which identifies program which identifies and evaluates water collection in the manholes.

manholes. The applicant further stated that this prevention prevention program program has been effective in monitoring monitoring and evaluating evaluating thethe exposure exposure of water to cable and cable supports located located in manholes. The staff noted during the the audit that in Corrective Report Report 04-03545, 04-03545, the applicant discovered discovered that the Manhole EMH-1 9A Manhole 1EMH-19A Duct 944 had 34 inches of water in itit during performance performance of its manhole manhole inspection inspection for water induced damage in 2004. The water was removed, and the lower induced damage lower cable tray was severely deteriorated deteriorated to the point where one of the ladder runs of the tray had fallen out and the tray tray support support brackets were also badly rusted. The applicant's manhole inspection was last applicant's manhole performed in September September 2006. The findings included included missing seals, cracked walls, corroded supports, and water intrusion, intrusion, but no cable damage was found. In reviewing cable damage corrective reviewing the corrective report, the staff noted noted that certain certain manholes had chronic flooding problems. These manholes, numbered 1EMH-8A, numbered EMH-BA, BB, 8B, and 15, are located located below grade near the intake intake structure and and repeatedly had water levels of 10 10 to 15 feet. Manholes Manholes 1EMH - BA&BB 8A&8B contain safety-related safety-related cables cables from both Units 1 and 2. Based on the above, the staff was concerned concerned that the the applicant's corrective applicant's corrective actions and periodic inspection for water collection in the manholes manholes were not adequate.

The applicant further stated that historical operating experienceexperience information information from 2001, 2001, included in the documentation documentation for Corrective Action 04-03545-104-03545-1, , was presented presented to the NRC Resident Resident Inspector on October Inspector October 26, 2001. historical information identified 2001. The historical identified certain manholes with with problems. These manholes, numbered chronic flooding problems. numbered 1EMH-8A, 8B, 8B, and 15, are located below grade structure and were repeatedly found to have water levels of 10 to grade near the intake structure 15 feet. The plant operating experience was used as input to the existing 15 existing BVPS manhole manhole inspection program. The applicant also stated that the program, inspection program, as described in LRA Section B.2.21, B.2.21, requires that the applicant take periodic actions, at least least once every two years, to prevent cables from being exposed to significantsignificant moisture. These include inspecting for water include water collection in cable manholes and conduit, and draining draining water, as needed.

The applicant further stated that as indicated indicated by the the corrective action to Corrective Report 04-03545, indication of water and cable submergence corrective submergence are visually evaluated evaluated by engineering Corrective Action Program, and further engineering using the BVPS Corrective actions are taken based on the evaluation.

During the regional onsite inspection performed during the week week of June 23, 2008, the staff staff found water in the manholes that contain safety-related safety-related cables. The staff staff determined determined that these these incidents demonstrate that the corrective actions actions described by the applicant have applicant have not been properly implemented, or were not adequate. In light of this operating operating experience, experience, the staff is concerned that inaccessible inaccessible medium-voltage medium-voltage cables that have have been submerged submerged for a period period of time may be degraded degraded and may not perform their intended intended function during the period of extended operation. The staff finds that the applicant applicant has not used the operating experience for operating experience program improvement improvement and enhancement, including including adjustment of the manhole manhole inspection inspection frequency frequency and/or using using automatic means, if frequent frequent inspection inspection fails to keep the cables dry.

In a letter dated September September 8, 2008, the applicant stated that LRA Section B.2.21 requires requires replacement replacement of the entire section, because because the program program is being being changed from a new new program that is consistent with the GALL Report, to a new plant-specific plant-specific program.

The staff noted that FENOC concluded inaccessible medium-voltage concluded that that all inaccessible medium-voltage cables within within the scope of the new plant-specific plant-specific program are suitable for operation in submerged water in a submerged water environment.

The BVPS practice practice of regular regular lube lube oil system analysis analysis is consistent consistent with industry experience in which operating experience which significant and potentially disabling failures could potentially disabling have been prevented by following this same policy. A specific example example is Information Notice, 2001-06 in which aa 40-fold increase described in NRC Information increase inin particle particle count for the lube lube oil in a. a high-head high-head SI pump thrust bearing bearing was not recognized recognized as a potential indicator indicator of bearing damage.

Other practices such as assessing the storage and distribution of Other good practices lubricating oil from the site warehouse lubricating warehouse helps helps to ensure that high quality contaminant-free oil is added to the lubricating systems for in-scope pumps and contaminant-free motors.

The BVPS Lubricating Lubricating Oil Analysis Program incorporates operating experience incorporates operating experience from the sampling sampling and testing of lubricating lubricating oil for the various in-scope pump and bearing packages. Operating experience motor bearing experience has shown that a precursor precursor event to bearing failures is elevated lubricating lubricating oil particulate concentration. The The program is designed to detect this elevated particulate concentration elevated particulate concentration which which preemptive actions allows preemptive actions such as oil replacement to be performed performed prior to loss loss of intended intended function. Current operating operating experience experience (Corrective (Corrective Action Program documents, Information documents, Information Notices, etc.) validates the effectiveness etc.) validates effectiveness of the BVPSBVPS Lubricating Oil Analysis Program. The BVPS Lubricating Lubricating Lubricating Oil Analysis Program Program has been effective effective at managing managing aging aging effects effects by periodically periodically sampling sampling and analyzing lubricating lubricating oil from these in-scope components.

The staff reviewed the operating experience experience provided in the LRA LRA and interviewed the applicant's applicant's personnel to confirm that the plant-specific operating technical personnel operating experience experience did not reveal any aging effects effects not bounded bounded by the GALL Report. The staff also confirmed confirmed that applicable aging effects and industry and plant-specific plant-specific operating operating experience have been evaluated and incorporated incorporated into the BVPS Lubricating Oil Analysis Analysis Program.

In LRA LRA Section B.2.27, the applicant applicant described described the existing Metal Fatigue of Reactor Coolant Boundary Program as Coolant Pressure Boundary as consistent with GALL GALL AMP X.M1, X.M1, "Metal Fatigue of Reactor Reactor Coolant Pressure Pressure Boundary."

The applicant stated stated that the Metal Fatigue of Reactor Reactor Coolant Pressure Pressure Boundary Program is a TLAA that uses preventive measures to mitigate fatigue cracking caused by anticipated cyclic cyclic strains in metal components of the RCPB. The preventive measures monitor and track critical thermal and pressure transients for RCS components to prevent prevent them from exceeding fatiguefatigue design limits. Critical transients are the subset of the design transients transients likely to approach approach or or exceed the number number of design cycles cycles during the Sixty-year sixty-year operating operating life of the units. These These critical transients include include plant heatup, plant cooldown, reactor trip from full power power (Unit 1),

inadvertent auxiliary spray, safety inadvertent safety injection injection activation (Unit 1), and RCS cold over-pressurization. The program pressurization. The program also monitors supplemental supplemental transients transients like the pressurizer pressurizer insurge insurge transient, selected chemical and and volume control system (CVCS)

(CVCS) transients, auxiliary feedwater auxiliary feedwater (AFW) injections, and RHR actuation (Unit 2). Before these transients exceed exceed the fatigue design design limit, the program program triggers preventive or corrective actions or both.

X.M1. The The staff performed performed its review of the "corrective actions," "confirmatory actions," and "administrative "administrative controls" program program elements as part of the staff's review of the applicant's Quality Assurance Assurance Program.

The staffs staff's evaluation evaluation of the Quality Assurance Assurance Program is provided in SER Section Section 3.0.4.

The staff reviewed reviewed the technical information information in LRA LRA Section B.2.27 and the applicant's applicant's onsite onsite documentation documentation supporting the applicant's applicant's conclusion conclusion that the program program elements elements are consistent consistent with the elements elements in the GALL Report. The staff also interviewed the applicant's technical staff staff to verify the description description of the LRA and its supplementing supplementing documents.

The staff determined determined that the applicant's MetalMetal Fatigue Fatigue of Reactor Reactor Coolant Pressure Pressure Boundary Program is based, in part, on a cycle counting process that is performed performed for the design basis basis transients transients that have been defined for the Units 1 and 2 facilities in LRA Table 4.3-2. The staff staff noted that the cycle counting counting is required required for these transients in accordance accordance with the applicant's applicant's Technical Specification (TS) 5.5.3, which reads as follows:

Technical Specification 5.5.3 Component Cyclic or Transient Limit Limit This program provides provides controls to track the UFSAR UFSAR Table 4.1-10 (Unit 1) and UFSAR UFSAR Table 3.9N-1 3.9N-1 (Unit (Unit 2), cyclic and transient occurrences occurrences to ensure that components are maintained components maintained within the design limits.

The staff noted that this TS requirement provided the applicant's applicant's basis for the cycle counting counting that is part of the "monitoring and trending" program element aspect of the applicant's applicant's program.

The applicant transients, which include include pressurizer insurge transient, selected CVCS transients, AFW injections and RHR RHR actuation that will be be monitored by Metal Fatigue of Reactor Reactor Coolant Pressure Boundary Program and stated that critical and supplemental these critical supplemental transients will be monitored and tracked in order to ensure that the fatigue design limit is is not exceeded. The staff noted that as part of the response, the applicant provided a table of the critical and supplemental transients that are required for monitoring for Units monitoring Units 1 andand 2, along with the basis of selection and the selection criteria of these transients. The staff further noted that the applicant selected selected these critical and supplemental transients because the projected cycles for these transients are expected expected to approach approach the design cycles during the period of extended operation.

Based on its review, the staff finds the applicant's response to RAI B.2.27-1 acceptable because because provided the complete list of critical and supplemental transients that will be the applicant has provided be monitored by the Metal Fatigue of Reactor Coolant Pressure Boundary Program Program and has has included an appropriate appropriate basis for selecting these transients to be monitored by the program during the period of extended operation. Therefore, Therefore, the staff's concern concern described in B.2.27-1 is resolved.

The staff noted that in LRA B.2.27, the applicant indicated indicated that supplemental transients transients are identified by the Metal Fatigue of Reactor identified Reactor Coolant Pressure Boundary Boundary Program Program for monitoring.

The staff required additional information information in order order to complete its review of this program.

In RAI B.2.27-7, dated May 28, 2008, the staff requested 28,2008, requested that the applicant provide provide additional information information related to the supplemental supplemental transients identified by the program for monitoring.

Specifically, Specifically, the applicant was asked to (a) identify the major components affected by the the transients and confirm that a related fatigue analysis has been updated; updated; (b) justify consistency between between supplemental supplemental transients and design transients, (c) explain the method used to monitor monitor these transients, and indicate indicate whether the number of number design design cycles for the supplemental transients will remain valid for the period of extended operation.

In its response to RAI B.2.27-7, dated July 11, 11, 2007, the applicant clarified that all supplemental transients listed in the LRA are applicable applicable to both Units 1 and 2. The applicant applicant continued in its response response by listing those components components that are affected by each of the transients transients (pressurizer (pressurizer insurge/outsurge, insurge!outsurge, selected CVCS, AFW injection and RHR activation). The staff noted that the the applicable analyses applicable analyses for the components specified components specified by the applicant applicant have have incorporated incorporated the the corresponding corresponding transients transients affecting affecting these components components and do not require require a revision, with the the exception exception of the ASME Class 1 portion of the Unit 2 charging piping. piping. The applicable applicable analyses analyses for the ASME Class 1 portion of the Unit 2 charging piping is part of the applicant's applicant's commitment commitment (Commitment (Commitment No. No.1)1) to perform perform a re-analysis and to incorporate incorporate the revised revised design cycles of the the selected selected CVCS transients.

The applicant stated that the AFW injection transient was incorporated incorporated into the original analysis analysis for the Unit Unit 2 reactor coolant pumps (RCPs), pressurizer and loop stop valves. However, Westinghouse Westinghouse did not identify this transient in the NSSS transients transients and; therefore, itit was not a part of the original design basis. The applicantapplicant specifically added this transient for the SGs as as part of the design design basis for the extended extended power uprate. The staff noted that the RHR Activation Activation for Unit 2 was part of the original design design basis, and was considered considered a supplemental supplemental transient

.because because the applicant expected expected that the cycles would exceed exceed the design cycles. HoweverHowever based based on its response response to RAI B.2.27-4, the applicant no longer expects these cycles to exceed the design cycles.

The staff noted that in its response to RAI B.2.27-7, the applicant is capable of monitoring monitoring thethe pressurizer insurge/outsurge, selected pressurizer insurge!outsurge, selected CVCS and AFW injection transient with the use of the the Plant Computer data archiving system.

acceptable. Therefore, the staff's concern concern described in RAI B.2.27-7 is resolved.

During the audit, the staff reviewed reviewed the onsite basis documents documents supporting supporting the LRA and and discussed its review with the applicant. The staff found that LR basis document document (FMP(FMP Program Program Document LRBV-PED-X.M1)

LRBV-PED-X.M1) Table Table 6.0-1, 6.0-1, element 10 stated that "The design transient transient assumed by original designdesign analysis will be sufficient for 60 years operation." The staff noted this sentence sentence is also stated in the operating experience experience Section of LRA Section Section B.2.27.

However, the annotation (a) of LRA Table 4.3-1 states that the projected 60-year cycles RHR cycles of RHR system piping are expected to exceed the design cycles cycles by 50 percent.

In RAI B.2.27-4, B.2.27 -4, dated May 28, 2008, the staff requestedrequested that the applicant applicant justify the the discrepancy discrepancy between between the text in the LRA and onsite basis documents documents and the annotation (a) of 4.3-1.

The The staff verified in the applicant's applicant's UFSAR and TSs that RHR is placed placed into service when the plant plant cools down from 350 35000 F to less than 200 20000 F. The applicant applicant noted that this method of counting is very dependent dependent on an accurate account accurate account of the plant modes and the transition between between ModeMode 3 and Mode Mode 4.

The staff noted that the applicant applicant had performed performed an evaluation, to obtain an accurateaccurate count from the plant mode history from Power Ascension Testing until October 15, 2003. The applicant's applicant's result from this recount was 31 events compared to Westinghouse's Westinghouse's count of 85 events. The The staff compared compared the results of the applicant's recount with LRA Table 4.3-2 and noted noted that Unit 2 has had 30 plant cooldown cooldown cycles.

Based on its review, the staff finds the applicant's response response to RAI B.2.27-4 RAI B.2.27 acceptable because

Operatingq Experience. In LRA AMP B.2.32, the applicant Operating applicant provided the following following operating operating experience evaluation for BVPS:

experience Microbiologically influenced Microbiologically influenced corrosion (MIC)(MIC) and macro-fouling macro-fouling have occurred occurred on occasion at BVPS within the River and Service Service Water Water systems and other heat exchangers which reject heat directly exchangers directly to the river. Those Those systems using water water from the Ohio River as a heat sink are collectively collectively referred to as the Open Cycle Cycle Cooling Water (OCCW) system.

MIC can result in pipe and component wall thinning, which if left unchecked, unchecked, can cause failure of the affected affected component. Macro-fouling Macro-fouling and MIC also produceproduce silting, which can lead to a decrease decrease in system flow and a subsequent reduction in heat removal. The OCCW program is designed designed for timely identification identification of the the macro-fouling which will allow corrective actions, such as symptoms of MIC and macro-fouling as component replacement, to be taken.

The auditaudit showed that a sufficient number of parameters are measured to detect measured detect abnormal conditions which could be indicative of MIC, MIC, macro-fouling, or silting. Biocide concentrations were maintained macro-fouling, maintained within specified bands, and associated systems were found to be treated and controlled to acceptable levels consistent with industry and NRC NRC guidelines. Adherence Adherence to specifications and regular monitoring recommended chemistry specifications monitoring of key system system flow parameters parameters provide reasonable reasonable assurance that the OCCW program will manage loss of material and reduction of heat transfer for in-scope effectively manage in-scope OCCW components.

The OCCW system program at BVPS satisfies GL 89-13 commitments commitments for managing managing aging effects due to biofouling, biofouling, corrosion, protective protective coating failures, and silting within system components. In October, 2004, an NRC audit was was conducted on the implementation implementation of Generic Letter, GL 89-13. The audit did not reveal any findings, however, suggested improvements were identified to further suggested improvements strengthen the OCCW system program. program. For example, a recommendation recommendation was made made to increase inspection and cleaning frequencies increase the inspection frequencies of OCCW system components components which would allow the program program to sooner identify a component in in the early early stages of material loss. The recommended recommended improvement, improvement, to modify the the monitoring program administrative monitoring program administrative procedure, was documenteddocumented within the the Corrective Corrective Action Program and incorporated incorporated into the program.

In its response to RAI B.2.33-1, B.2.33-1, dated July 21, 21, 2008, the applicant applicant stated that the intent of LRA Section Section B.2.33 B.2.33 was not to define an AMP with 10 elements. The applicant confirmed confirmed that the the intent of LRA Section B.2.33 B.2.33 was to identify a commitment, as specified in the GALL Report Report and stated that the commitment wording commitment wording was included in LRA Appendix B as a a pointer and for ease of review. The applicant clarified clarified the issue and revised LRA Sections A.1.33 and B.2.33 B.2.33 to delete the misleading misleading text, further stating that other sections of the LRA are also revised to delete references references to the AMP, and to include include references references to the commitments commitments (Commitment (Commitment No. 18 18 and Commitment Commitment No. 20) provided in LRA Tables Tables A.4-1 (Unit (Unit 1) A.5-1 (Unit (Unit 2),

respectively. The staff reviewed the applicant's applicant's response and verified that the applicant applicant has has amended amended the LRA as noted above. The staff noted that the amendments amendments are consistent consistent with with Westinghouse-designed Westinghouse-designed RV internals internals components found in the GALL Report, Table IV.B2.

Based on its review, the staff finds the applicant's applicant's response to RAI B.2.33-1 acceptable because because amended the AMRs on management the applicant has amended management of cracking, loss of fracture fracture toughness, changes changes in dimension, and loss of preload of the RV internals components components for Units 1 and 2 to be consistent with their corresponding AMRs in the GALL Report, Table IV.B2. The staff further finds that the applicant (Commitments No. 18 and No. 20) to develop applicant has committed (Commitments develop a plant-specific plant-specific PWR Vessel Internals Monitoring AMP that will implement activities from industry investigations (including operating experience), as applicable investigations (including managing aging applicable to BVPS, for managing effects on reactor internals, prior to the period of extended extended operation. Therefore, the staff's staff's concern concern described in RAI B.2.33-1 is resolved.

The staff also noted that in the GALL Report, Table IV.B2, the staff recommends that the type of commitment commitment discussed discussed in the Staff Evaluation Evaluation be credited for aging management management of the RV internals in Westinghouse-designed Westinghouse-designed PWRs. The staff reviewed the technical technical and regulatory information in the applicant's applicant's PWR Vessel InternalsInternals Program. The staff noted that although the the applicant applicant had provided provided the appropriate appropriate commitment (Commitments (Commitments No. 18 in LRA Table A.4-1 for Unit 1 and No. 20 in LRA Table A.5-1 for Unit 2) 2) for its RV internals components, components, the the applicant applicant did not identify identify which RV internals internals components commodity at Units 1 and 2 were were within the scope of the PWR Vessel Internals Program Program and the regulatory regulatory commitments.

program Operating Experience. The staff also reviewed reviewed the operating operating experience, including including samples of condition reports, and interviewed interviewed the applicant's applicant's technical staff to confirm that the plant-specific plant-specific experience did not reveal any degradation operating experience degradation not bounded by industry experience. experience.

However, during its review review audit, the staff noted that a temporarytemporary construction construction opening was was created in 2006 for the Unit 1 SG and reactor head replacements. Inspections during RFO 17 replacements. Inspections revealed degradation (2006) revealed degradation from the inaccessible inaccessible side of the steel liner, for which the applicant applicant could not identify aa root-cause root-cause from observations observations in field or from lab analysis.

analYSis. To ensure the the essential essential leak-tight condition of the containment, the staff identified three issues where where additional clarifications and justifications additional clarifications justifications were needed to complete complete the review.

In RAI 8.2.3-1, In B.2.3-1, dated May 8, 2008, that staff requested requested that the applicant provide provide information information related related to the minimum required thickness of the liner; discuss discuss the possibility possibility and severity of similar corrosion corrosion at other locations, including Unit 2 containment; containment; and justify whether the the corrosion is active. Furthermore, Furthermore, the staff requested the applicant applicant discuss the use of the GALL 3-105

Report which recommends further evaluation of plant-specific plant-specific programs to manage this aging effect for inaccessible inaccessible areas, if corrosion is significant.

In its response to RAI B.2.3-1, B.2.3-1, dated June June 16, 2008, the applicant stated:

Analyses and evaluations of the Unit 1 containmentcontainment liner corrosion corrosion in 2006 were performed for FENOC FENOC by several several vendors that specialize in these types of analyses analyses and by the FirstEnergy FirstEnergy Beta Laboratory.

The Shaw Group, Inc., evaluatedevaluated the condition condition of the Unit 1 containment containment liner regarding the extent of the degradation degradation and effects on intended intended function following following the discovery of the containment containment liner corrosion in 2006. The evaluation included evaluation included consideration of the impactimpact of an additional additional 20 years of operation as a result of license renewal renewal on the recurring Integrated Leak Rate Test loading. loading.

In the Shaw Shaw Group's report, design basis calculations calculations originally developed developed for the the BVPS Unit 1 containment containment liner were used to demonstrate demonstrate that the degraded conditions found on the liner did not adversely adversely affect its mechanical/structural mechanical/structural function as a leak-tight leak-tight membrane. The thickness of the remaining sound metal was determined determined to be adequate adequate to maintain maintain the design safety function of the the liner. In addition, the capacity capacity of the concrete concrete containment structure to withstand Design Basis Accident loadings was not adversely affected.

Of the three areas of corrosion identified, two were replaced replaced with new plate plate material. The third area showed minimal wall loss at the deepest deepest pit, and was left in place for further monitoring.

monitoring. In In addition to initial "baseline" "baseline" ultrasonic ultrasonic thickness thickness measurements in accordance measurements accordance with Table IWE-2500-1, examination category E-C, IWE-2500-1, examination itit was recommended recommended that the third area area of degradation degradation be mapped mapped on the inside inside of the containment containment liner for future UT examinations.

examinations. ItIt was recommended recommended that that this area be examined examined for the next three inspection inspection periods. IfIf no change in liner liner thickness thickness was detected detected after three inspection inspection periods, it was determined determined that the the area would require no additional inspections. Further engineering evaluation was was recommended if the thickness changed. FENOC has scheduled recommended scheduled additional UT UT examinations as recommended by The Shaw Group, Inc., for the three inspection inspection periods following the 2006 RFO when the degradation degradation was discovered.

discovered.

A material material analysis was performed performed by the FirstEnergy FirstEnergy Beta Laboratory Laboratory on the the corroded steel liner areas and sample pieces of concrete to aid in determining determining a cause of the corrosion. The following conclusionsconclusions were drawn concerning concerning thethe corrosion activities:

  • The corrosion was general general pitting corrosion corrosion (wastage) with no evidence evidence of stress corrosion microbiological attack. The metallographic corrosion or microbiological metallographic work performed by Beta Labs found the pitting to be rounded in nature nature with no no crack crack like projections. The examination examination of the corrosion product product trapped in the deep pits identified identified no unusual unusual levels of elements elements that were not expected expected to be present. No preferential preferential corrosion attack was observed observed on the sample piece with the weld or on the welds around around the Nelson studsstuds 3-106

welded to the liner plate. Some crevice corrosion corrosion was observed in the the cross section of the studs where the flash weld could trap contaminates.contaminates.

    • The corrosion occurred occurred after welding and construction of the liner plate plate since the corrosion pitting was even across the weld, the heat affected affected (HAZ) and both edges of the weld where weld prep would have zone (HAZ) have preferential corrosion occurred occurred. No preferential occurred at the weld or HAZ.
  • " necessary elements for corrosion (oxygen and water) were present The necessary present throughout the construction phase of Unit 1, from the fabrication and throughout erection erection of the liner plate through through the completion of concrete concrete pours for the the containment structure. During this timeframe, water, in the form top of the containment of the wetting methodology used during the concrete concrete pour sequences sequences and weather weather (rain and snow), could accumulate accumulate in areas areas between the liner plate and the concrete structure. Corrosion Corrosion activities activities are likely to have have initiated during this construction construction period.
    • Access to these necessary necessary elements for corrosion corrosion activity became became significantly limited once the concrete structure structure was completed. Exposure Exposure to water sources sources all but ceased, and the concrete/steel concrete/steel interface interface was no no longer exposed to the atmosphere re-oxygenation.

atmosphere for re-oxygenation.

    • The corrosion process process consumes oxygen, and, once it is depleted, corrosion can not be sustained at a high rate due to the limited supply of oxygen between between the concrete concrete and the liner plate following fabrication.
    • No corrosive agents or corrosion catalysts, such as chlorides, could be be identified identified on or in the steel liner liner plate. Additionally, no corrosion agents were found in the pitted areas of the liner plate or in the concrete concrete materials tested in concentrations materials concentrations that would be of concern. However, it must be considered considered that such materials materials may have existed in local areas local areas and were removed removed during the water hydrolyzing process that was used to hydrolyzing process remove remove the exterior containment containment concrete.

"* Approximately Approximately 1% 1% of the observable observable liner plate (portion removed for the the construction construction opening) opening) contained corroded areas and a much smaller contained corroded smaller percentage percentage of the rebar surface area had evidence evidence of corrosion. So, it is reasonable reasonable to assume that the concreteconcrete did not contain corrosive corrosive agents, and that corrosion elements elements (water and oxygen) oxygen) were not present inin abundant abundant amounts. This finding would support the general general conclusion that no general corrosion corrosion is active active in the area between between the liner plate and the the concrete.

    • The corrosion is localized for reasons reasons that can not be determined determined with certainty. However, small breaks breaks in the mill scale surface surface or other surface surface imperfections imperfections can provide the initiation sites for pitting (oxygen cell corrosion) during the time of construction corrosion) construction when oxygen and water were known known to be present.

3-107 3-107

    • The concrete concrete did contain contain small void areas at the concrete/steel concrete/steel interface.

These voids would most likely have filled with water during the the construction construction phase. During the post-construction post-construction life of the liner, these locations locations could also serve as an accumulation accumulation point for any moisture that enters the concrete concrete structure. However, the area of the containment containment liner liner where the concrete concrete was found to have small voids at the steel/concrete steel/concrete interface interface had no corrosion corrosion activity.

"

  • Foreign material has been identified by other power plants that removed removed the liner plate from the inside of containment containment leaving the concrete in in place. The foreign debris was identifiable in these instances instances since thethe corrosion product was available for analysis. At BVPS, little or no corrosion product no corrosion product remained following the water hydrolyzing, corrosion product hydrolyzing, so no no conclusions conclusions could be drawn regarding the source of the corrosion.

A vendor materials specialist specialist was commissioned commissioned to perform aa corrosion assessment assessment of the corroded corroded steel liner, and stated stated that the primary primary source of passivation of the steel used in fabrication of the containment containment liner, studs and and rebar is the concrete itself. The passivity of the steel depends depends upon the quality quality of concrete in contact with the steel and the intimate contact the concrete contact of the steel to the the concrete. The vendor concluded that, where the containment containment steel liner, studs studs and rebar rebar are in contact with the concrete concrete cover, the containment containment steel liner at BVPS Unit 1 would passivated state and not !?ubject would be in a passivated subject to oxygen concentration concentration cell corrosion. The visual inspection inspection of the removed cutout and rebar identified identified that the majority majority (over 99%)

99%) of the surfaces in contact contact with the the concrete concrete were passive to an oxygen concentration concentration cell corrosion mechanism.

In LRA Section Section B.2.16, the applicant stated that its Fire Protection Program is consistent with the GALL AMP Xl. M26, however, the applicant XI. M26, applicant claimed an exception exception to the "parameters monitored/inspected" element regarding monitoredlinspected" regarding frequency of functional functional testing for Halon and carbon dioxide dioxide systems. The applicant applicant took this exception because itit conducts exception because conducts the functional tests onceonce every 18 months, which is less frequent than the GALL AMP XI.M26 guideline of at least one every one test for the detection of aging degradation degradation every 6 months. The applicant also performs the the Halon and carbon dioxide system inspections 18-month intervals. However, to ensure the inspections at 18-month the optimum optimum integrity integrity of the in-scope Halon and carbon dioxide dioxide systems, the applicant will inspect each each system at least once every 6 months during during the period of extended extended operation.

The staff reviewed UFSAR Sections Sections 9.10.4 9.10.4 (Unit 1) and 9.5.1.7.4 (Unit (Unit 2) for CO C022 and Halon Halon systems systems to determine determine if if the CLB specified specified any frequency of inspections. The staff found that the the UFSAR only states that in-servicein-service inspection inspection and testing will be periodically periodically performed. Since the CLB does does not specify any frequency for inspections, the staff determined determined that additional information was required to complete the review.

In RAI B.2.16-3, dated May 22, 2008, the staff requested May 22,2008, requested that the applicant applicant provide the bases bases different inspection for using a different inspection frequency frequency than the recommended recommended GALL AMP XI.M26 XI.M26 frequency of once every six months.

Staff Evaluation.

Evaluation. The staff reviewed reviewed those portions of the applicant's Fire Water System Program that the applicant applicant claimed consistency with GALL AMP XI.M27 XI.M27 and found they are are consistent consistent with this GALL AMP. The staff also confirmed confirmed that the plant program contains all of the elements of the referenced referenced GALL programprogram and the conditions conditions at the plant are bounded by the conditions conditions for which the GALL Report is evaluated. The staff conducted conducted onsite interviews interviews with the applicant's technical staff to confirm these results.

The staff finds the applicant's Fire Water System Program Program acceptable acceptable because because it conforms to to the recommended recommended GALL AMP XI.M27, with the enhancements enhancements as discussed discussed below.

In comparing the elements in the applicant's applicant's AMP to GALL AMP XI.M27, the staff found that the the applicant applicant has taken enhancements taken enhancements as follows:

"

  • Added Added a program program requirement in the "Parameters monitored/inspected" to perform flow test or inspection inspection of all accessible fire water headers headers
  • " Added program program requirements in the "detection of aging effects" element to identify locations ifif visual inspections are to be performed; visual inspections performed; allow test or inspection inspection results from accessible Section accessible Section of pipe to be extrapolated extrapolated for inaccessible pipe; all accessible headers headers and piping to be flow tested; and require testing or replacement replacement of sprinkler heads in service service for 50 years.

The staff reviewed the enhancements enhancements and compared the changes with the GALL AMP XI,M27 XI.M27 recommendations recommendations for the enhanced enhanced elements. The staff determined determined that implementation implementation of these enhancements enhancements will make make the applicant's applicant's Fire Water System Program consistent consistent with the the GALL GALL AMP XI.M27.

The applicant also included an enhancement enhancement in the "detection of aging effects" element that states enhancement described states that the program enhancement described under the "scope of program" element is necessary. However, there is no enhancement enhancement identified identified in the "scope of program" element.

In RAI 8.2.17-1, B.2.17-1, dated May 22, 2008, the staff requested requested that the applicant applicant clarify this this discrepancy.

In its response to RAI 8.2.17-1, B.2.17-1, dated July 24, 2008, the applicant stated that the reference to "scope program" element was an error and that there is no-enhancement "scope ofof program" element was an error and that there is no enhancement in the "scope of program" element.

The subject sentence sentence should have referenced referenced the "parameters monitored/inspected" monitored/inspected" element.

th The staff noted noted that the applicant has revised LRA Section B.2.17, 5 th paragraph, under 8.2.17, 5 under subheading subheading "Detection of Aging Effects" as follows:

Also, the program program enhancement enhancement described described under under the Parameters Parameters Monito~ed/lnspected Monitored/Inspected program element necessary for consistency element is necessary consistency with this this program element.

Based on its review, the staff finds the applicant's 8ased applicant's response to RAI 8.2.17-1 B.2.17-1 acceptable because because the applicant has revised LRA Section 8.2.17 B.2.17 to make the enhancement enhancement wording consistent with this program element. Therefore, the staffs concern concern described in RAI B.2.17-1 8.2.17-1 is resolved.

During the review of the Fire Water System Program basis document, the staff noted noted that the the applicant applicant states that the Unit 1 fire hydrant gasket inspection is performed gasket inspection performed every 18 months, compared to the GALL GALL AMP recommendation recommendation of 12 months. However, the staff determined determined that the applicant applicant did not include include this as an exception exception in the LRA because gaskets gaskets were considered consumables and will be replaced as necessary.

In RAI 8.2.17-2, B.2.1 7-2, dated dated May 22, 2008, the staff requested requested that the applicant applicant justify the basis for this excluding the 18 month Unit 1 fire hydrant gasket inspection as an exception gasket inspection exception to the 12 recommendation of the GALL month recommendation GALL AMP.

In its response to RAI 8.2.17-2, B.2.17-2, dated July 24, 2008, the applicant applicant stated that based on ANSI B31.1 831.1 and the ASME Code Boiler 80iler and Pressure Vessel Code, Section III, the subcomponents subcomponents of pressure retaining components pressure retaining components are not pressure pressure retaining parts. Therefore, these subcomponents are not relied on to form a pressure-retaining SUbcomponents pressure-retaining function and are not subject to an AMR. The applicant further stated that althoughalthough these gaskets perform perform no license renewal intended function, their condition is monitored intended monitored by the Fire Water System Program Program and they are replaced as necessary.

replaced The staff reviewed reviewed the response and noted that the condition of the fire hydrant gaskets gaskets is monitored monitored by the Fire Water System Program and the gaskets are replaced replaced as necessary.

However, the GALL AMP recommended recommended frequency for these gaskets gaskets is once a year whereas whereas the applicant performs these inspections inspections once every 18 18 months. The staff determines the determines that the applicant's response response does not address why this is not an exception. Therefore, the staff issued exception. Therefore, issued September 3, 2008, requesting a follow-up RAI by letter dated September requesting that the applicant applicant justify the basis basis for this excluding excluding the 18 month Unit 1 fire hydrant gasketgasket inspection exception to the 12 inspection as an exception month recommendation recommendation of the GALL AMP.

Therefore, the staff finds the response acceptable and considers the issue closed.

During the review of the Fire Water System Program basis document, the staff noted that the the applicant stated that fire hydrant hose hydraulic tests are performed performed at frequencies different different recommended frequency of once every 12 months. However, the applicant than the GALL AMP recommended did not include this as an exception in the LRA because because hoses were considered considered consumables consumables and would be replaced as necessary.

In RAI B.2.17-3, dated May 22,2008, 22, 2008, the staff requested that the applicant applicant justify why this this frequency difference difference is not an exception.

In its response to RAI B.2.17-3, B.2.17-3, dated July 24, 2008, the applicant stated that fire hoses hoses are consumables, and are routinelyroutinely tested, inspected, and replaced replaced when necessary. Criteria for inspection and replacement are based based on accepted accepted industry standards (e.g., NFPA-1962). The industry standards The applicant applicant further stated that while these consumables consumables are within the scope of license renewal, they do not require an AMR.

The staff reviewed reviewed the applicant's response and acknowledgesacknowledges that the the condition of the fire fire hydrant hoses is monitored monitored by the Fire Water System Program Program and the hoses are replaced replaced as as necessary. However, the GALL GALL AMP recommended recommended frequency for hydraulic hydraulic testing of hoses is once once aa year, whereas the applicant applicant performs performs these tests at various frequencies frequencies and its response response to the RAI RAI does does not address address why this test frequency frequency is not an an exception.

In its response response to RAI B.2.17-4, dated July July 24, 2008, the applicant stated stated that the 2005 condition condition report indicates that further chemical treatment at that time would not have eliminated the MIC MIC in the piping welds. Because Because of the large number of potentially susceptible susceptible welds in the piping, piping, the applicant applicant replaced the entire length of affected affected pipe. The applicant also stated that continuing continuing chemical treatments, testing, and inspection inspection of the new pipe provide reasonable reasonable assurance assurance that MIC will be adequately adequately managed managed prior to loss of intended function.

The applicant also stated that testing of the fire water system is performed performed in accordance accordance with applicable applicable NFPANFPA codes and standards, including requirements associated including testing requirements associated with the fire fire suppression suppression water system, spray and sprinkler sprinkler system, and fire hose stations. The fire water systems are normally normally maintained at required operating pressure pressure and monitored monitored such that loss of system pressure is immediately immediately detected and corrective corrective actions actions initiated. The applicant explained that ultrasonic explained ultrasonic tests are capable of effectively evaluating evaluating pipe wall thickness inner thickness and inner diameter. The applicant further stated that continuingcontinuing chemical treatments, testing, continuouscontinuous pressure pressure monitoring, inspections (including UT), incorporation inspections (including incorporation of site-specific site-specific operating operating experience, and evaluation evaluation of degradation degradation using the Corrective Corrective Action Program, provide provide reasonable reasonable assurance that the fire water system's intended intended functions will be maintained for the the extended operation.

LRA AMP B.2.20 provides the following experience (OE) evaluation for BVPS:

following operating experience The Fuel Oil Chemistry Program is an existing program program that utilizes sampling sampling and and analysis to ensure that adequate adequate diesel fuel quality is maintained maintained to prevent loss loss of material and fouling in the various in-scopein-scope fuel oil systems. Exposure Exposure of fuel oil to contaminants such as water and particulates is also minimized by periodic periodic draining draining of accumulated accumulated water, tank interior interior cleaning, and by verifying verifying the quality of new oil before its introduction introduction into the storage tanks.

Water Water has occasionally occasionally been discovered discovered in various BVPS diesel fuel oil storage storage tanks during during sampling activities. In accordance accordance with sampling and analysis analysis procedures, any detected detected water is removed from the affected tank as part of the the sampling process.

There have been instances during the past five years, been multiple, but infrequent, instances where where fuel oil particulate concentrations concentrations were near or aboveabove the Technical Specification limit for Emergency Specification Emergency Diesel Generator fuel oil storagestorage tanks. Four Corrective Action Program items were identified since 2002, which documented Corrective documented elevated elevated fuel oil particulate particulate levels in Emergency Emergency Diesel Generator fuel oil storage Generator storage and day tanks. In all cases, corrective actions were taken such as recirculatingrecirculating the tank contents through through a particulate particulate filter. Other than these events, fuel oil sample results from 2001 through 2005 reveal that fuel oil quality is being being maintained maintained in compliance compliance with industry standards. Regular analysis analysis and confirmation of diesel fuel quality provide reasonable assurance confirmation assurance that the program program is effectively effectively managing fuel oil chemistry.

A sampling schedule schedule for diesel generator generator fuel oil tanks has been established, established, to allow timely identification identification of excessive concentrations of water and/or excessive concentrations particulates, which will minimize tank loss of material. SamplingSampling frequency frequency is adequate adequate as evidenced evidenced by the relatively relatively few instances of particulate levels particulate levels exceeding exceeding the Technical Specification limit. A recent CR identified Technical Specification identified elevated particulate particulate levels which which had yet to exceed the limit, but were monitored monitored with with sufficient frequency to identify sufficient frequency identify a rising trend.

important element An important element of fuel oil (or any other) analysis is operation operation of the testing laboratory. Fuel oil samples from BVPS are sent to Beta Laboratory Laboratory (a First Energy subsidiary) after an initial set of factors are measured measured at the BVPS site.

The laboratory completes the oil analysis by measuring measuring parameters parameters such as as viscosity, flash point, and percent sulfur.

A fleet oversight Quality Assurance audit was conducted to assess the operation practices practices and regulatory regulatory compliance compliance of the Beta Laboratory facility. The principal tool for this assessment assessment was the FENOC Quality Assurance Assurance Program Manual.

The results of the audit reveal that Beta Lab is effective in performing performing analyses analyses of the fuel oil samples from BVPS, however however multiple areas improvement were areas for improvement identified identified and Corrective Corrective Action Program items items were generated generated to document document and track the recommended recommended improvements. The Quality Assurance audit process audit process provides an additional level of assurance provides assurance that the fuel oil chemistry program will continue continue to effectively effectively monitor and manage manage fuel oil chemistry.

Comply with applicable NRC Orders Orders and provide a commitment commitment in the FSAR supplement supplement to submit a plant-specific AMP to implement applicable (1) Bulletins Bulletins and Generic Generic Letters and (2) staff-accepted staff-accepted industry industry guidelines.

This approach approach to aging management management conforms conforms to the staffs recommended aging staff's recommended management aging management guidelines guidelines provided provided in the following sections sections of the SRP-LR:

  • " Section 3.1.2.2.16 - Cracking Cracking due due to Primary Water Water Stress Corrosion Cracking Cracking (PWSCC) (applicable (applicable to steel steam generator generator upper and lower lower heads, tubesheets, and tube-to-tube tube-to-tube sheet welds made or clad with nickel-alloy nickel-alloy and nickel-alloy nickel-alloy pressurizer pressurizer spray heads)

This recommended recommended aging management management approach approach does not apply to the nickel-alloy nickel-alloy materials materials used in the fabrication of upper penetration nozzles upper RV closure head penetration nozzles and welds, SG tubes, SG sleeves, SG plugs, or SG divider plates. For these nickel-alloy nickel-alloy components, the GALL Report management recommendations has different aging management recommendations which may be found in the applicable AMRs AMRs in GALL Report Report Tables IV.A2 for RV components or IV.D1 for recirculating recirculating SG designs.

Staff Evaluation. The staff reviewed information in LRA Section B.2.28, the applicant's reviewed the information applicant's license renewal basis document for this AMP, and other supporting information and documents documents that pertain pertain to the procedural p~ocedural and implementation implementation controls for this AMP, against the regulatory criteria summarized summarized in the above Staff Evaluation section.

The staff noted noted that, in LRA Tables 3.1.2-1 3.1.2-3, the applicant credited its Nickel-AlloyNickel-Alloy Nozzles and Penetrations Nozzles Penetrations Program, as the basis for managing cracking cracking due due to PWSCC in the the nickel-alloy component majority of the nickel-alloy component commodity groups groups used in the fabrication of the RVs, pressurizers, Class 1 piping systems, and SGs for Units 1 and 2. The staff also noted that the pressurizers, the applicant's applicant's Nickel-Alloy Nozzles and Penetration Program does not have a specific specific corresponding program in the GALL Report, Volume 2, Chapter XI. The staff determined corresponding determined that that ifif the applicant was tying its basis for aging management Nickel-Alloy Nozzles and management to the Nickel-Alloy Penetrations Program, Penetrations Program, then the AMP must be defined as plant-specific plant-specific in the LRA.

In RAI B.2.28-1, B.2.28-1, dated June requested that the applicant June 5, 2008, the staff requested applicant justify why the the Nickel-Alloy Nozzles Nickel-Alloy Nozzles and Penetration Penetration Program Program had not been identified as a plant-specific plant-specific AMP and the programprogram elements elements for this AMP provided in the LRA. (Note: The staff evaluates evaluates the applicant's applicant's response to RAI B.2.28-1 B.2.28-1 later in this evaluation in conjunction with the staff's staff's evaluation evaluation of the applicant's applicant's response to RAI B.2.28-2).

ThisThis clarification clarification removed removed the perceived linkage to the applicant's Nickel-Alloy Nozzles applicant's stated Nickel-Alloy Nozzles and Penetrations Penetrations Program, which was only included included as a review guide and therefore no program elements are described. Therefore, Therefore, the staffs concern concern described described in RAI B.2.2B-1 B.2.28-1 is resolved.

The staff noted noted that in the specific AMR items for PWR nickel-alloy components in GALL Report nickel-alloy components Tables IV.A2, IV.C2, and IV.D1,IV.D1, the staff recommends recommends that the type of commitment mentioned mentioned in the staff evaluation evaluation be credited, in part, as the basis for managing managing the effects of agingaging for the the a vast majority of the nickel-alloy nickel-alloy components within the scope of the LRA. The staff reviewed reviewed the technical and regulatory information information in the Nickel-Alloy Nickel-Alloy Nozzles and Penetrations Penetrations Program and verified that the applicant applicant had provided the following commitments commitments for its nickel-alloy nickel-alloy components in LRA Table A.4-1 for Unit 1 (Commitment (Commitment No. 15) 15) and in LRA Table Table A.5-1 for for Unit 2 (Commitment (Commitment No. 17): 17):

The staff verifiedverified that the the applicant has made the applicable applicable amendments amendments of the LRA.

Based on its review, the staff finds that the applicant's applicant's responses to RAls RAIs B.2.28-1 B.2.28-1 and B.2.28-2 are acceptable acceptable because the applicant has amended amended the LRA to delete the Nickel-Alloy Nozzles Nickel-Alloy Nozzles Penetrations Program and the UFSAR and Penetrations UFSAR supplement for this AMP from the scope of license license renewal and has amended renewal amended the AMR items for the nickel-alloynickel-alloy Class 1 components components to directly refer to the applicant's aging management management commitments commitments for ASME ASME Code Class 1 nickel-alloy nickel-alloy components components and pressure pressure retaining retaining welds. Therefore, the staff's concerns described described in RAIs RAls B.2.28-1 and RAI 2.28-2 2.28-2 are resolved.

With respect to the acceptability of these commitments, the staff finds the provisions of LRA Commitments No. 15 for Unit 1 and No. 17 for Unit 2 acceptable Commitments because they conform to the acceptable because the commitment commitment criteria recommendations discussed in the Staff Evaluation Section of this recommendations discussed this evaluation.

Thus, for these non-fire protection non-fire protection protection system components, the staff found this to be acceptableacceptable in meeting the staff's recommendation recommendation SRP-LR Section A.1.2.3.4 because, although the one-time in SRP-LR inspection program that does not one-time inspection not sufficient to confirm that loss of re-inspection frequency, the inspection will be sufficient have a periodic re-inspection material due to selective selective leaching is not occurring occurring in the components components or else to prompt prompt the the applicant to take appropriate appropriate corrective actions under under the program's program's "corrective actions" programprogram element ifif it is confirmed that selective leaching is occurring in these components. Thus, the the staff finds that the one-time non-fire protection system one-time inspection for the non-fire components meets the system components the program does not rely on waiting for a A.1.2.3.4 because the program staff's criterion in SRP-LR Section A.1.2.3.4 component component failure to occur as an aging managementmanagement basis for the AMP.

The staff noted that the program's selective leaching includes both visual examination leaching technique includes examination methods and qualitative hardness hardness tests of the material. The staff finds this to be appropriate appropriate because any porosity that is induced by selective leaching is a large-scale because large-scale effect that can be be noticed noticed by visual examinations examinations and because drop in the component because a drop component hardness hardness properties, as as hardness tests, may indirectly monitored for by the hardness monitored indirectly be indicative of a dropdrop in the fracture toughness in the component materials.

Scope of the Program.

Program. LRA Section B.2.43 states that, "The scope of the program program consists of the Boral Boral neutron neutron absorbing absorbing material material in the High Density Spent Fuel Storage Storage Racks at BVPS BVPS program applies only to BVPS Unit 1, because the BVPS Unit 2 Spent Fuel Storage Unit 1. The program Storage Racks do not use BoralBoral as a neutron absorber."

The staff confirms that the "scope of the program" program program element element satisfies satisfies the guidance guidance in in SRP-LR Section A.1.2.3.1, A.1.2.3.1, since the staff confirmed Boral was only used in BVPS Unit 1 confirmed that Boral spent fuel pool and BVPS Unit 2 uses Boraflex. Therefore, Therefore, the staff finds this program program element element acceptable.

Preventive Preventive Actions. LRA Section B.2.43 states that, "The program is a condition monitoring monitoring program program that does not contain preventive preventive actions."

The staff confirms that the "preventive actions" program program element satisfies satisfies the guidance guidance in in SRP-LR SRP-LR Section Section A.1.2.3.2 since BVPS Unit 1 has a condition monitoring monitoring program.

applicable 3.1.2.1.2 Aging Management Management of Loss of Fracture Toughness Toughness due to Thermal Aging in CASS CASS Reactor Reactor Vessel Internal (RVI) (RVI) Components Components In the applicant's applicant's letter of July 21, 2008, the applicant amended July 21, amended its AMRs in LRA Table 3.1.2-2 3.1.2-2 that pertain to the management management of loss of fracture toughness due to thermal aging embrittlement embrittlement and neutron irradiation embrittlement neutron irradiation embrittlement of its cast austenitic stainless steel (CASS) reactor reactor vessel internal (RVI)

(RVI) components. In this amendment amendment of the LRA, the applicant applicant changed is basis for for managing loss of fracture managing fracture toughness due to thermal embrittlement in the CASS RVI thermal aging embrittlement components from AMP B.2.40, "Thermal Aging and Neutron Irradiation Irradiation Embrittlement Embrittlement of Cast Austenitic Austenitic Stainless Stainless Steel (CASS) Program," to the applicant's managing the applicant's commitments for managing the aging aging effects attributed attributed to RVI components, components, as provided in Commitment No. 18 of UFSAR UFSAR Supplement Table A.4-1 for Unit 1 and Commitment No. 20 of UFSAR Supplement UFSAR Supplement Table A.5-1 for Unit 2.

The corresponding corresponding AMRs in the GALL Report that relate to these AMR items are AMR item 80 80 in Table Table 1 of the GALL Report, RevisionRevision 1, Volume 1 (GALL(GALL1)1) and AMR items IV.B2-21 and IV. B2-37 in Table IV.B2-37 Table IV.B2 of the GALLGALL Report, Revision Revision 1, Volume 2 (GALL2),

(GALL2), as applicable applicable to management of loss of fracture toughness due to thermal aging embrittlement the management embrittlement in CASS CASS Westinghouse-designed RVI upper Westinghouse-designed upper support support columns columns and lower support castings and lower lower support plate columns. These GALL1 GALL 1 and GALL2 AMR items identify that the environment that environment can induce induce loss of fracture fracture toughness toughness of these CASS components components as a result of thermal aging embrittlement and neutron irradiation embrittlement irradiation embrittlement embrittlement is the borated reactor coolantcoolant at an elevated elevated temperature in excess of 250°C (i.e.,

temperature (i.e., >482°F), and as exposed exposed to an integrated integrated neutron fluxflux (i.e., neutron (i.e., neutron fluence).

In these AMRs, the staff recommends that a program program corresponding corresponding to GALL AMP XI.M13, XI.M13, "Thermal Aging and Neutron Irradiation Embrittlement Irradiation Embrittlement of Cast Austenitic StainlessStainless Steel (CASS)" be credited for aging management management of loss of fracture toughness toughness in these CASS CASS components.

The staff noted noted that the applicant's applicant's amendment amendment of these stated AMRs in LRA Table 3.1.2-2 changed the aging management management basis in the AMRs AMRs from being consistent consistent with GALL GALL AMR items items IV.B2-21 IV.B2-21 and IV.B2-37 IV.B2-37 to being consistent consistent with the recommendations recommendations in these GALL AMR GALL AMR itemsitems except for the fact that the commitments commitments in Commitment No. 18 of UFSAR Supplement Supplement Commitment No. 20 of UFSAR Supplement Table A.4-1 for Unit 1 and Commitment Supplement Table A.5-1 for Unit 2 are now beingbeing credited credited as the basis basis for aging management management in lieu of an AMP corresponding corresponding to 3-215 3-215

GALL GALL AMP XI.M1 XI.M13, 3, "Thermal Aging and Neutron Irradiation Irradiation Embrittlement Embrittlement of Cast Austenitic Austenitic Stainless Stainless Steel (CASS)."

In the 2005 update of the SRP-LRSRP-LR and the GALL GALL Report, the NRC NRC took a recommended recommended position that aging management management of PWR PWR vessel internals needs to be done done on a consistent basis among among licensed licensed PWRs in the U.S. to account account for the fact that not all of the PWR RVI components are ASME Code Class and to account for the fact that additional additional aging management measures management necessary for some of the non-ASME measures may be necessary non-ASME Code Class PWR PWR RVI RVI components. Hence, Hence, the staff updated updated its aging management management basis in the AMRs for PWR PWR RVI components in the GALL components GALL Report through the following recommendedrecommended commitment commitment that was was recommended to be adopted recommended UFSAR Supplements adopted in the UFSAR Supplements for PWR LRAs:

"(1)

"( 1) participate in the industry programs for investigating investigating and managing managing agingaging effects effects on reactor internals; internals; (2) evaluate and implement implement the results of the industry programs as applicable to the reactor internals; internals; and (3) upon completion of these programs, but not less than 24 months before entering the period of extended extended operation, operation, submit an inspection inspection plan for reactor internals internals to the NRC for review and approval."

Thus, for current Westinghouse-designed Westinghouse-designed PWR LRAs pending staff approval approval (including that for for BVPS Units 1 and 2), the staffs staffs AMR basis for managing managing the aging effects attributed to Westinghouse-designed Westinghouse-designed (as well as to Babcock Babcock and Wilcox-designed Wilcox-designed and Combustion Engineering-designed)

Engineering-designed) PWR RVI components components were amended to state:

"The AMP column column was changed to delete referencereference to XI.M16 (AMP M16 was was also deleted deleted from the GALLGALL report) and instead require a commitmentcommitment in the the FSAR Supplement to apply industry industry programs programs to be developed developed in the future for proper management management of reactor internals. Also, added to the further evaluation evaluation column the requirement requirement for the licensee licensee commitment to be confirmed."

The staff noted that the commitment that is recommendedrecommended by the staff includes a provision for PWR applicants applicants to submit an inspection inspection plan for their RVI components that is based on the the augmented inspection industry's augmented recommendations for PWR RVI components to the inspection program recommendations the NRC for review and approvalapproval at least two years prior to entering the period of extended operation. The staff verified that the applicant operation. applicant includes the applicable applicable commitment commitment for the RVI components components in Commitment Commitment No. 18 of LRA UFSAR Supplement Supplement Table A.4-1 A.4-1 for BVPS Unit 1 and in Commitment Commitment No. 20 of LRA UFSAR Supplement Supplement Table A.5-1 for BVPS Unit 2.

The staff also noted that the applicant's amended amended basis to credit the commitments commitments for managingmanaging the aging effects for the BVPS RVI components components (including the management management loss of fracture fracture toughness toughness in the CASS RVI componentscomponents as a result of thermal aging embrittlement embrittlement and neutron irradiation embrittlement) conformance with the staffs recommended embrittlement) is in conformance recommended commitment for RVI components as given components given in the applicable applicable AMRs of GALL2 Table Table IV.B2. As aa result of this review and the bases stated above, the staff finds that the applicant's amended and alternate basis for applicant's amended managing loss of fracture toughness managing toughness in the CASS RVI components as a result of thermal aging aging embrittlement, and neutron neutron irradiation embrittlement is embrittlement acceptableacceptable because it is in conformance conformance with staffs recommendation in GALL2 that a commitment commitment be placed on the LRA to manage manage thethe aging effects that are applicable applicable to the BVPS RVI components.
