Rajender Auluck, Chief Aging Management of Structures, Electrical, and Systems Branch Division of License Renewal Office of Nuclear Reactor Regulation David L. Pelton, Chief Aging Management of Plant Systems Branch Division of License Renewal Office of Nuclear Reactor Regulation Introduction An onsite audit was conducted by the U.S. Nuclear Regulatory Commission (NRC) project team at the Salem Nuclear Generating Station (SNGS or Salem), Units 1 and 2. On February 19, 2010, the NRC audit team completed the onsite audit of aging management programs (AMPs).
The purpose of this audit was to examine the applicant's AMPs for the Salem plants and to verify the applicant's claim of consistency with the corresponding NUREG-801, "Generic Aging Lessons Learned (GALL) Report" AMPs. Exceptions to the GALL Report AMP elements are evaluated separately as part of the NRC staff's review of the license renewal application (LRA) and documented in the staff's Safety Evaluation Report (SER).
The Standard Review Plan for Review of License Renewal Applications for Nuclear Power
Plants (NUREG-1800, Revision 1) provides the staff guidance for reviewing an LRA. The Standard Review Plan allows an applicant to reference in its LRA the AMPs described in the GALL Report. If an applicant credits an AMP for being consistent with a GALL Report program, it is incumbent on the applicant to ensure that the plant program contains all of the elements of the referenced GALL Report program. The applicant's determination should be documented in an auditable form and maintained onsite.
During this audit, the staff audited program elem ents 1-6 (scope, preventive actions, parameters monitored or inspected, detection of aging effects, monitoring and trending, and acceptance criteria), and program element 10 (operating experience), of the applicant's AMPs claimed to be consistent with the GALL Report against the equivalent elements of the associated AMP described in the GALL Report, unless otherwise indicated in this audit report. Program elements 7-9 (corrective actions, confirmation process, and administrative controls) were audited by another NRC project team during the Scoping and Screening Methodology Audit and are evaluated separately. In addition, the staff verified the conditions at the plant were bounded
by the conditions for which the GALL Report program was evaluated.
The staff also examined the applicant's program bases documents and related references for these AMPs and interviewed SNGS representatives to obtain additional clarification related to the AMPs.
Salem Nuclear Generating Station LRA Section B.2 Aging Management Programs
LRA Section B.2.1 1801 Chapter XI AMPs
LRA AMP B.2.1.1 ASME Section XI Inservice Inspection, Subsections IWB, IWC, and IWD
In the Salem Nuclear Generating Station (SNGS) license renewal application (LRA), the applicant states that AMP B.2.1.1, "ASME Section XI Inservice Inspection, Subsections IWB, IWC, and IWD", is an existing program that is consistent with the program elements in Generic Aging Lessons Learned (GALL) Report aging management program (AMP) XI.M1, "ASME Section XI Inservice Inspection, Subsections IWB, IWC, and IWD." To verify this claim of consistency the staff audited the LRA AMP. This audit report considers program elements 1-6 (scope of program, preventive actions, parameters monitored or inspected, detection of aging effects, monitoring and trending, and acceptance criteria), and program element 10 (operating experience) and the description of the program as contained in the LRA Appendix A.2.1.1, Updated Final Safety Analyses Report (UFSAR) Supplement. Program elements 7-9 (corrective actions, confirmation process, and administrative controls) are audited as part of the scoping and screening methodology audit. Issues identified but not resolved in this report are addressed in the Safety Environmental Report (SER).
During its audit, the staff interviewed the applicant's staff, and reviewed onsite documentation provided by the applicant. The staff also conducted an independent database search of the applicant's operating experience database using the keywords: "Class 1," "weld,"
"examination," "ISI," "inspection," "indication," "crack," "flaw," and "internal."
The table below lists the documents which were reviewed by the staff and were found relevant to the audit. These documents were provided by the applicant or were identified in the staff's search of the applicant's operating experience database.
Relevant Documents Reviewed Document TitleRevision / DateSH-PBD-AMP-XI.M1 Salem and Hope Creek Program Basis Document - ASME Section XI Inservice Inspection, Subsections IWB, IWC, and IWD Revision 1 7/21/2009 N/A Salem Units 1 and 2 Operating Experience Summary for: Notifications 20282812, 20231520, 20043770, 20234047, 20233744, 20008368, 20276340, 20276340, 20276363, 20127259, 20062945; Computer generated reports related to these notifications.
N/A Salem Unit 1 - Inservice Inspection Program Third 10-Year Interval Long Term Plan Revision 1 11/2003 N/A Salem Unit 2 - Inservice Inspection Program Third 10-Year Interval Long Term Plan Revision 1 11/2003 ERA-AA-330 Conduct of Inservice Inspection Activities Revision 7 ERA-AA-330-01 Section XI Pressure Testing Revision 6 ERA-AA-330-02 Inservice Inspection of Section XI Welds and Components Revision 6 ER-SH-330-0009 PSEG Nuclear Repair Program Manual for the Control of R and NR Certificates of Authorization Revision 1 10/1/2008 Based on its review of the listed documents and interview with the applicant, the staff confirmed that the applicant's plant configuration is such that all components specified in applicable ASME Code Section XI, Subsections IWB, IWC, and IWD, examination categories can be inspected and that none have been excluded from inspection based on consideration of the burden upon the licensee that could result if requirements to inspect the component were imposed on the facility. This is consistent with the scope of program described in GALL AMP XI.M1, Element 1.
The staff noted that SNGS' current third 10-year inservice inspection interval is in accordance with 10 CFR 50.55a, but is based on ASME Code Section XI, 1998 edition through 2000 addenda, which is different from the code edition and addenda referenced in the GALL Report.
However, the staff has previously determined that use of code editions and addenda dated 1995 or later and approved in accordance with 10 CFR 50.55a is acceptable and that an applicant's use of such code editions during its current inservice inspection interval should not be classified as exceptions to recommendations in the GALL AMP XI.M1.
During the audit of program elements 1-6, the staff found that:
Elements 1, 2, 3, 5, and 6 (scope of program, preventive actions, parameters monitored/inspected, monitoring and trending, and acceptance criteria) of the LRA AMP are consistent with the corresponding elements of the GALL Report AMP; and Sufficient information was not available to determine whether element 4 (detection of aging effects) of the LRA AMP is consistent with the corresponding element of the GALL Report AMP.
In order to obtain the information necessary to verify whether the LRA program element 4 is consistent with the corresponding element of the GALL Report AMP, the staff indicated that it would consider issuing a request for additional information (RAI) for the following subjects:
In element 4 of the LRA AMP, the program basis document states that for the current risk informed inservice inspection interval (RI-ISI) alternative requirements apply to Categories B-F, B-J, C-F-1 and C-F-2 piping welds; and the description of the AMP in LRA Section B.2.1.1 stated, "The Salem ASME Section XI program also includes a Risk-Informed Inservice Inspection (RI-ISI) program." In the GALL Report AMP, the recommendations in element 4 are based on ASME Code Section XI requirements for examinations as specified for the various component examination categories in IWB-2500, IWC-2500 and IWD-2500. It is not clear to the staff that the statements in the SNGS program basis document and in the LRA are consistent with the recommendations in the GALL Report because it is not clear whether the statements in the LRA AMP and in LRA Section B.2.1.1 refer to only the current ISI interval, which does not carry forward into the period of extended operation, or whether the statements mean that the applicant is proposing in the LRA to continue implementation of alternate methods during the period of extended operation.
During the audit of program element 10 (operating experience), the staff found that:
The operating experience provided by the applicant and identified by the staff's independent database search is bounded by industry operating experience (i.e., no previously unknown aging effects were identified by the applicant or the staff); and The operating experience provided by the applicant and identified by the staff's independent database search is sufficient to allow the staff to verify that the LRA AMP, as implemented by the applicant, is sufficient to detect and manage aging effects during the period of extended operation.
The staff also audited the description of the LRA AMP provided in the UFSAR Supplement. The staff found this description to be consistent with the description provided in the SRP-LR and, therefore, acceptable.
Based on this audit the staff:
Verified that most of the LRA program elements 1-6 are consistent with the corresponding program elements in the GALL R eport while identifying certain aspects of LRA program elements 1-6 for which additional information or additional evaluation is required before consistency can be determined;
Verified that the operating experience is sufficient to indicate that the LRA AMP, as implemented by the applicant, is sufficient to detect and manage aging; and

Although it is not specifically referenced in GALL AMP XI.M3, NUREG-1339, "Resolution of Generic Safety Issue 29: Bolting Degradation or Failure in Nuclear Power Plants," includes recommendations that thread lubricants containing MoS 2 not be used because its use increases the likelihood of cracking due to stress corrosion in high strength bolts. The staff finds the applicant's restrictions with regard to use of MoS 2 to be consistent with GALL AMP XI.M3, Element 2, which states that preventive actions includes use of acceptable surface treatments and stable lubricants. During the audit of program elements 1-6, the staff found that:
Elements 1, 2, 3, 5, and 6 (scope of program, preventive actions, parameters monitored/inspected, monitoring and trending, and acceptance criteria) of the LRA AMP were consistent with the corresponding elements of the GALL Report AMP; and
Sufficient information was not available to determine whether element 4 (detection of aging effects) of the LRA AMP was consistent with the corresponding element of the GALL Report AMP.
In order to obtain the information necessary to verify whether LRA program element 4 is consistent with the corresponding element of the GALL Report AMP, the staff indicated that it would consider issuing an RAI for the following subject:
In its review of element 4 of the LRA AMP, the staff found that the applicant performs volumetric (not volumetric and surface) examination of reactor head closure studs when they are removed from the reactor vessel flange. In the GALL Report AMP element 4 states that Examination Category B-G-1 for pressure-retaining bolting greater than 2 inches diameter in reactor vessel specifies surface and volumetric examination of studs when they are removed from the reactor vessel. It is not clear to the staff that these statements are consistent because the applicant does not routinely perform surface examinations of reactor vessel head closure studs when they are removed from the vessel flange.
During the audit of program element 10 (operating experience), the staff found that:
The operating experience provided by the applicant and identified by the staff's independent database search is bounded by industry operating experience (i.e., no previously unknown aging effects were identified by the applicant or the staff); and
The operating experience provided by the applicant and identified by the staff's independent database search is sufficient to allow the staff to verify that the LRA AMP, as implemented by the applicant, is sufficient to detect and manage aging effects during the period of extended operation.
The staff also audited the description of the LRA AMP provided in the UFSAR Supplement. The staff found this description to be consistent with the description provided in the SRP-LR and, therefore, acceptable.

LRA AMP B.2.1.8 Flow Accelerated Corrosion In the SNGS LRA, the applicant states that AMP B2.1.8, "Flow Accelerated Corrosion," is an existing program that is consistent with an exception to the program elements in GALL Report AMP XI.M17, "Flow-Accelerated Corrosion." To verify this claim of consistency, the staff audited the LRA AMP. This audit report considers program elements 1-6 (scope of program, preventive actions, parameters monitored or inspected, detection of aging effects, monitoring and trending, and acceptance criteria) and program element 10 (operating experience) and the description of the program as contained in the UFSAR Supplement. Program elements 7-9 (corrective actions, confirmation process, and administrative controls) are audited as part of the scoping and screening methodology audit.
One exception affects LRA program element 1 (scope of program) and element 4 (detection of aging effects). In the GALL Report AMP, these program elements recommend using the EPRI guidelines contained in Nuclear Safety Analysis Center-202L-R2, "Recommendations for an Effective Flow Accelerated Corrosion Program" (NSAC-202L-R2), to assure that the structural integrity of all carbon steel lines and valve bodies containing single-phase and two-phase high-energy fluids is maintained. In the LRA, the applicant states that the flow-accelerated corrosion (FAC) AMP is based on the EPRI guidelines found in NSAC-202L-R3. The staff previously reviewed NSAC-202L-R3 (NUREG-1929, Volume 2) and determined that it is equivalent to NSAC-202L-R2 and in addition, allows the use of the Averaged Band Method, which is another method for determining wear of piping components from ultrasonic testing (UT) inspection. The staff notes that EPRI documents are created using industry experience over several years and finds that the Averaged Band Method provides another method to determine the wear of piping components from UT inspections. The staff finds this method to be more accurate, thereby resulting in better prediction of remaining life and less rework. The staff finds the use of EPRI NSAC-202L-R3 acceptable because it will continue to allow the applicant to manage wall thinning due to FAC on the internal surfaces of carbon and low alloy steel piping and components that contain both single-phase and two-phase high-energy fluids. During its audit, the staff reviewed onsite documentation provided by the applicant. The staff also conducted an independent search of the applicant's operating experience database using the keywords: "flow accelerated corrosion," "FAC," and "corrosion."

During the audit, the staff found that:
Elements 2 (preventive actions), 3 (parameters monitored or inspected), 5 (monitoring and trending), and 6 (acceptance criteria) of the LRA AMP were consistent with the corresponding elements of the GALL Report AMP; and
Elements 1 (scope of program) and 4 (detection of aging effects) of the LRA AMP were not strictly consistent with the corresponding elements of the GALL Report AMP but sufficient information was available to allow the staff to determine that these elements of the LRA AMP are equivalent to the corresponding elements of the GALL Report AMP.
The basis for the staff's determination that elements 1 (scope of program) and 4 (detection of aging effects) of the LRA AMP are equivalent to the corresponding GALL Report AMP is that NSAC-202L-R3 is essentially equivalent to NSAC-202L-R2 and provides an equivalent function of managing the FAC AMP.
During the audit of program element 10 (operating experience), the staff found that:
The operating experience provided by the applicant and identified by the staff's independent database search is bounded by industry operating experience (i.e., no previously unknown aging effects were identified by the applicant or the staff); and The operating experience provided by the applicant and identified by the staff's independent database search is sufficient to allow the staff to verify that the LRA AMP, as implemented by the applicant, is sufficient to detect and manage aging effects during the period of extended operation.
The staff also audited the description of the LRA AMP provided in the UFSAR Supplement. The staff found this description to be consistent with the description provided in the SRP-LR and, therefore, acceptable.
Based on this audit the staff:

LRA AMP B.2.1.9 Bolting Integrity In the SNGS LRA, the applicant states that AMP B.2.1.9, "Bolting Integrity," is an existing program with an enhancement and an exception that is consistent with the program elements in GALL Report AMP XI.M18, "Bolting Integrity." To verify this claim of consistency the staff audited the LRA AMP. This audit report considers program elements 1-6 (scope of program, preventive actions, parameters monitored or inspected, detection of aging effects, monitoring and trending, and acceptance criteria) and program element 10 (operating experience) and the description of the program as contained in the UFSAR Supplement, LRA Section A.2.1.9. For the Bolting Integrity Program, the audit report also considers specific recommendations in the GALL Report related to program element 7 (corrective actions). More general GALL Report recommendations related to program elements 7-9 (corrective actions, confirmation process, and administrative controls) are audited as part of the scoping and screening methodology audit. This audit report does not consider the sufficiency of exceptions. Issues identified but not resolved in this report are addressed in the SER.
There is one enhancement. The enhancement affects LRA program element 7 (corrective actions). This enhancement expands on the existing program element by modifying the existing program to state that the following bolting materials should not be reused: a) Galvanized bolts and nuts; b) ASTM A490 bolts; and c) Any bolt and nut tightened by the turn of the nut method.
In LRA Section A.5, License Renewal Commitment List, Commitment Number 9, the applicant committed to implement this enhancement prior to the period of extended operation.
There is one exception. The exception affects LRA program element 5 (monitoring and trending). In the GALL Report AMP, this program element recommends that if bolting connection for pressure retaining components (not covered by ASME Section XI) is reported to be leaking, then it may be inspected daily, and that if the leak rate does not increase the inspection frequency may be decreased to biweekly or weekly. Alternatively, this program element in the LRA states that the applicant uses its Corrective Action Program to determine an appropriate inspection frequency for identified leaks in bolting connections.
During its audit, the staff interviewed the applicant's staff, and reviewed onsite documentation provided by the applicant. The staff also conducted an independent search of the applicant's operating experience database using the keywords: "bolt," "nut," "preload," "torque," "leak,"
"thread," and "gasket."

Because these EPRI guidance documents are referenced in GALL AMP XI.M18, Elements 1 and 2, the staff finds the applicant's incorporation of guidance from these documents into its Bolting Integrity Program to be acceptable. The staff conducted its audit of LRA program elements 1-6 based on the contents of the existing program as modified by the proposed enhancements. Aspects of program element 5 (monitoring and trending) of the LRA AMP associated with the exception were not evaluated during this audit. Aspects of these program elements that are not associated with the exception were evaluated and are described below.
During the audit, the staff found that:
Elements 3, 4, 5, and 6 (parameters monitored orinspected, detection of aging effects, monitoring and trending, and acceptance criteria) of the LRA AMP are consistent with the corresponding elements of the GALL Report AMP; and
Sufficient information was not available to determine whether elements 1 and 2 (scope of program, and preventive actions) of the LRA AMP are consistent with the corresponding elements of the GALL Report AMP.
In order to obtain the information necessary to verify whether LRA program elements 1 and 2 are consistent with the corresponding elements of the GALL Report AMP, the staff indicated that it would consider issuing RAIs for the following subjects:
In its description of the LRA AMP, the applicant states that component support and structural bolting are managed as part of the Structures Monitoring Program, crane and hoist bolting is managed as part of the Inspection of Overhead Heavy Load and Light Load (Related to Refueling) Handling Systems Program, aging management of heating and ventilation bolted joints is managed by the External Surfaces Monitoring Program, and bolting in a buried environment is managed by the Buried Piping Inspection Program. In the GALL Report AMP, element 1 states that the program covers bolting within the scope of license renewal, including 1) safety-related bolting, 2) bolting for nuclear steam supply system (NSSS) component supports, 3) bolting for other pressure retaining components, including non-safety related bolting, and 4) structural bolting (actual measured yield strength 150 ksi). Also, in the GALL Report AMP element 2 states that selection of bolting material and use of lubricants and sealants is in accordance with the guidelines of EPRI NP-5769, and the additional recommendations in NUREG-1339, and the bolting replacement activities include proper torquing and application of appropriate preload based on the EPRI documents. It is not clear to the staff that the applicant's statement about the LRA AMP is consistent with the recommendations of the GALL Report AMP because it is not clear to the staff that all recommendations credited with managing the aging effects of bolting in the elements of GALL AMP XI.M18 are included in other programs that the applicant credits with managing aging effects of bolting. Also it is not clear to the staff how procurement, control of lubricants and sealants, application of appropriate preloads, and proper torquing of bolts are incorporated in the other programs credited by the applicant because those programs primarily involve inspection activities.
During the audit of program element 10, (operating experience), the staff found that:
The operating experience provided by the applicant and identified by the staff's independent database search is bounded by industry operating experience (i.e., no previously unknown aging effects were identified by the applicant or the staff); and The operating experience provided by the applicant and identified by the staff's independent database search is sufficient to allow the staff to verify that the LRA AMP, as implemented by the applicant, is sufficient to detect and manage aging effects during the period of extended operation.
The staff also audited the description of the LRA AMP provided in the UFSAR Supplement, LRA Section A.2.1.9. The staff found this description to be consistent with the description provided in the SRP-LR and, therefore, acceptable.
Based on this audit the staff:
Verified that most of the LRA program elements 1-6 are consistent with the corresponding program elements in the GALL R eport while identifying certain aspects of LRA program elements 1-6 for which additional information or additional evaluation is required before consistency can be determined; Verified that the operating experience is sufficient to indicate that the LRA AMP, as implemented by the applicant, is sufficient to detect and manage aging; and Verified that the description provided in the UFSAR Supplement is an adequate description of the program.

LRA AMP B.2.1.17 Aboveground Steel Tanks In the SNGS LRA, the applicant states that AMP B.2.1.17, "Aboveground Steel Tanks," is an existing program with enhancements, that is consistent with the program elements in GALL Report AMP XI.M29, "Aboveground Steel Tanks." To verify this claim of consistency the staff audited the LRA AMP. This audit report considers program elements 1-6 (scope of program, preventive actions, parameters monitored or inspected, detection of aging effects, monitoring and trending, and acceptance criteria) and program element 10 (operating experience) and the description of the program as contained in the UFSAR Supplement. Program elements 7-9 (corrective actions, confirmation process, and administrative controls) are audited as part of the scoping and screening methodology audit. Issues identified but not resolved in this report are addressed in the SER.
The first enhancement affects LRA program elements 4, 5, and 6 (detection of aging effects, monitoring and trending, and acceptance criteria). This enhancement expands on the existing program element by adding ultrasonic inspection of the fire water storage tanks. The enhancement is provided to measure corrosion of bottom surfaces on those specific tanks, which are mounted on concrete pads, where visual inspection is not practicable due to inaccessibility.
The second enhancement affects LRA program elements 2, 4, 5, and 6 (preventive actions, detection of aging effects, monitoring and trending, and acceptance criteria). This enhancement expands on the existing program element by adding visual inspection of the grout and steel/concrete interfaces in addition to the visual inspection of the Fire Water Storage Tank surfaces. Note that the fire protection water storage tanks are the only type of aboveground steel tanks at SNGS that are in-scope for this AMP.
In A.2.1.17 of the LRA, the applicant committed to implement these enhancements prior to the period of extended operation.

LRA AMP B.2.1.18 Fuel Oil Chemistry In the SNGS LRA, the applicant states that AMP B.2.1.18, "Fuel Oil Chemistry," is an existing program with enhancements and exceptions that is consistent with the program elements in GALL Report AMP XI.M30, "Fuel Oil Chemistry." To verify this claim of consistency, the staff audited the LRA AMP. This audit report considers program elements 1-6 (scope of program, preventive actions, parameters monitored or inspected, detection of aging effects, monitoring and trending, and acceptance criteria) and program element 10 (operating experience) and the description of the program as contained in the UFSAR Supplement. Program elements 7-9 (corrective actions, confirmation process, and administrative controls) are audited as part of the scoping and screening methodology audit. Issues identified but not resolved in this report are addressed in the SER.
The first enhancement affects LRA program elements 1 (scope of program), 2 (preventive actions), 3 (parameters monitored or inspected), and 4 (detection of aging effects). This enhancement provides equivalent requirements for fuel oil purity and fuel oil testing, as described by the Standard Technical Specifications.
The second enhancement affects LRA program elements 1 (scope of program), 3 (parameters monitored or inspected), 4 (detection of aging effects), 5 (monitoring and trending), and 6 (acceptance criteria). This enhancement provides analysis for particulate contamination in accordance with modified ASTM 2276-00 Method A. The modification consists of using a filter with a pore size of 3.0 microns instead of 0.8 microns.
The third enhancement affects LRA program elem ents 1 (scope of program), 2 (preventive actions), 3 (parameters monitored or inspected), and 7 (corrective actions). This enhancement requires the addition of biocides, stabilizers and corrosion inhibitors as determined by fuel oil sampling or inspection activities.
The fourth enhancement affects LRA program elements 1 (scope of program), 2 (preventive actions), 3 (parameters monitored or inspected), 4 (detection of aging effects), and 5 (monitoring and trending). This enhancement provides quarterly analysis for bacteria in new and stored fuel oil.
The fifth enhancement affects LRA program elements 1 (scope of program), 2 (preventive actions), 3 (parameters monitored or inspected), and 4 (detection of aging effects). This enhancement requires visual inspection of the internal surfaces of the 350-gallon fire pump day
tanks (S1DF-1DFE21 and S1DF-1DFE23) that have been drained for cleaning and sediment removal. Ultrasonic thickness examination of tank bottoms is also included.
The sixth enhancement affects LRA program elem ents 1 (scope of program), 2 (preventive actions), 3 (parameters monitored or inspected), 4 (detection of aging effects), and 5 (monitoring and trending). This enhancement provides API gravity and flash point testing of
new fuel prior to unloading the new fuel.
The seventh enhancement affects LRA program elements 1 (scope of program), 2 (preventive actions), 3 (parameters monitored or inspected), and 4 (detection of aging effects). This enhancement provides visual inspection of the internal surfaces of the diesel fuel oil storage tanks (S1DF-1DFE1, S1DF-1DFE2, S2DF-2DFE1 and S2DF-2DFE2) that have been drained for cleaning and sediment removal. Ultrasonic thickness examination of tank bottoms is also included.
The eighth enhancement affects LRA program elements 1 (scope of program), 3 (parameters monitored or inspected), and 4 (detection of aging effects). This enhancement verifies the absence of any significant aging effects of each of the 550-gallon diesel fuel oil day tanks, by performing a one-time inspection.
In Appendix A, Table A.5 of the LRA, in Commitment No. 18, the applicant committed to implement these enhancements prior to the period of extended operation.
The first exception affects LRA program elements 1 (scope of program), 3 (parameters monitored or inspected), 4 (detection of aging effects), and 6 (acceptance criteria). The GALL Report AMP requires periodic sampling of tan ks in accordance with the manual sampling standards of ASTM D 4057-95 (2000). The applicant stated that the 20,000-barrel fuel oil storage tank (S1DF-1DFE13) samples are single point samples obtained from the tank drain line located off of the bottom of the tank. This sample is not in accordance with the manual sampling standards as described in ASTM D 4057. The applicant further stated that the sample results are more likely to capture contaminants, water, and sediment, thus making this a conservative sample location for fuel oil containments.
The second exception affects LRA program elements 1 (scope of program), 3 (parameters monitored or inspected), 4 (detection of aging effects), and 6 (acceptance criteria). The GALL Report AMP requires periodic sampling of tan ks in accordance with the manual sampling standards of ASTM D 4057-95 (2000). The applicant stated that the 350-gallon fire pump day tanks (T-565) samples are single point samples obtained from the tank sight glass drain line located a few inches above the bottom of the tank. This sample is not in accordance with the manual sampling standards as described in ASTM D 4057. The applicant further stated that for fuel oil storage tanks of less than 159 cubic meters spot sampling recommendations in ASTM D 4057-95 (2000) include a single sample from the middle (a distance of one-half of the depth of liquid below the liquid's surface). The 350-gallon Fire Pump Day Tanks are 1.3 cubic meters so the spot sampling recommendations in ASTM D 4057 are applicable. Although the actual sample location for tanks is lower than prescribed by the ASTM D 4057 standard, the sample results are more likely to capture contaminants, water, and sediment, thus making this a conservative sample location for fuel oil containments.
The third exception affects LRA program elements 1 (scope of program), 3 (parameters monitored or inspected), 4 (detection of aging effects), and 6 (acceptance criteria). The GALL Report AMP requires periodic sampling of tan ks in accordance with the manual sampling standards of ASTM D 4057-95 (2000). The applicant stated that the 30,000-gallon diesel fuel oil storage tanks (S1DF-1DFE1, S1DF-1DFE2, S2DF-1DFE1 and S2F-1DFE2) samples consist of 4 samples drawn from 2 locations on the tank. One is from the level instrumentation block drain, which is located a few inches above the bottom of the tank. The remaining three samples are taken from the sump drain, which is located on the other side of the tank and is from the bottom of the tank. This sample is not in accordance with the manual sampling standards as described in ASTM D 4057. The applicant further stated that for fuel oil storage tanks of less than 159 cubic meters spot sampling recommendations in ASTM D 4057-95 (2000) include a single sample from the middle (a distance of one-half of the depth of liquid below the liquid's surface).
The 30,000-gallon diesel fuel oil storage tanks are 113.6 cubic meters so the spot sampling recommendations in ASTM D 4057 are applicable. Although the actual sample locations for the tanks are lower than prescribed by the ASTM D 4057 standard, the sample results are more likely to capture contaminants, water, and sediment, thus making this a conservative sample location for fuel oil containments.
The fourth exception affects LRA program elements 1 (scope of program), 2 (preventive actions), 3 (parameters monitored or inspected), 4 (detection of aging effects), 5 (monitoring and trending), and 6 (acceptance criteria). The GALL Report AMP requires periodic sampling, draining, cleaning, and internal inspection of tanks, to reduce the potential for loss of material by exposure to fuel oil contaminated with water and microbiological organisms. The applicant stated that multilevel sampling, tank bottom draining, cleaning, and internal inspection of the 550-gallon diesel fuel oil day tanks (S1DF-1DFE3, S1DF-1DFE4, S1DF-1DFE5, S2DF-1DFE3, S2DF-1DFE4 and S2DF-1DFE5) is not periodically performed. Instead, the applicant stated that fuel oil from the 550-gallon day tanks is recirculated back to the 30,000-gallon storage tanks quarterly. To confirm the absence of any significant aging effects, the applicant will perform a one-time inspection of each of the 550-gallon day tanks and the condition will be entered into the corrective action process for resolution.
The fifth exception affects LRA program elements 1 (scope of program), 2 (preventive actions), 3 (parameters monitored or inspected), 5 (monitoring and trending), and 6 (acceptance criteria). The GALL Report AMP requires the additions of biocides, stabilizers, and corrosion inhibitors to prevent degradation of the fuel oil quality. The Salem Fuel Oil Chemistry AMP does not require the addition of biocides, stabilizers, and corrosion inhibitors, but instead requires their use only in response to test results that indicate biocides, stabilizers, and corrosion inhibitors are needed.

The LRA states that guidelines from EPRI TR-112657, "Revised Risk-Informed Inservice Inspection Evaluation Procedure, Rev. B-A," were used for identifying susceptible piping instead of EPRI Report 1000701. The staff noted that it is not clear if the welds with the highest likelihood of degradation will be inspected, (e.g., welds with the highest stress but not necessarily in the high to medium risk categories). The staff also noted that it is unclear if socket welds are included in the high to medium risk categories and if they will be subject to inspection.
GALL AMP XI.M35, element 3 (parameters monitored/inspected), states that inspections will detect cracking in ASME Code Class 1 small-bore piping. The LRA states that socket welds that fall within the weld examination sample will be examined using a visual examination (VT-2). The staff notes that a visual inspection of the outside diameter will not detect cracking initiated from the inside of the socket weld before leakage occurs (e.g., stress corrosion cracking).
During the audit of program element 10 (operating experience), the staff found that:
The operating experience identified by the staff's independent database search and supplemented by the applicant is bounded by industry operating experience (i.e., no previously unknown aging effects were identified by the applicant or the staff); and The operating experience provided by the applicant and identified by the staff's independent database search is sufficient to allow the staff to verify that the LRA AMP, as implemented by the applicant, is sufficient to detect and manage aging effects during the period of extended operation.
The staff also audited the description of the LRA AMP provided in the UFSAR Supplement.
The staff found that sufficient information was not available to determine whether the description provided in the UFSAR Supplement was an adequate description of the LRA AMP.
In order to obtain the information necessary to verify the sufficiency of the UFSAR Supplement program description, the staff will consider issuing RAIs for the following subjects:
Appendix A of the LRA states that this program is a part of the SNGS Risk-Informed Inservice Inspection program. The staff noted that it is not clear if the welds with the highest likelihood of degradation will be inspected, (e.g., welds with the highest stress but not necessarily in the high to medium risk categories). The staff also noted that it is unclear if socket welds are included in the high to medium risk categories and if they will be subject to inspection.
Appendix A of the LRA states that in lieu of performing one-time volumetric inspections of socket welds for pipe size less than 4" NPS and greater than or equal to NPS 1, the examination method and frequency will be VT-2. The staff notes that a visual inspection of the outside diameter will not detect cracking initiated from the inside of the socket weld before leakage occurs (e.g., stress corrosion cracking).
Based on this audit the staff:
Verified that most of the LRA program elements 1-6 are consistent with the corresponding program elements in the GALL R eport while identifying certain aspects of LRA program elements 1-6 for which additional information or additional evaluation is required before consistency can be determined; Verified that the operating experience is sufficient to indicate that the LRA AMP, as implemented by the applicant, is sufficient to detect and manage aging; and Identified a need for additional information regarding the adequacy of the program description in the UFSAR Supplement.
LRA AMP B.2.1.24 External Surfaces Monitoring In the SNGS LRA, the applicant states that AMP B.2.1.24, "External Surfaces Monitoring," is a new program that is consistent with the program elements in GALL Report AMP XI.M36, "External Surfaces Monitoring." The applicant committed to implementing this program prior to the period of extended operation in LRA Section A.2.1.23. To verify this claim of consistency the staff audited the LRA AMP. This audit report considers program elements 1-6 (scope of program, preventive actions, parameters monitored or inspected, detection of aging effects, monitoring and trending, and acceptance criteria) and program element 10 (operating experience) and the description of the program as contained in the UFSAR Supplement.
Program elements 7-9 (corrective actions, confirmation process, and administrative controls) are audited as part of the scoping and screening methodology audit. Issues identified but not resolved in this report are addressed in the SER.

M88472 and M88473) 4/15/1994 The staff noted that the applicant's Flux Thimble Tube Inspection is classified as a "new" program because in 1993 the applicant discontinued the eddy current testing (ECT) of flux thimble tubes recommended in NRC Bulletin 88-09, "Thimble Tube Thinning in Westinghouse Reactors." The staff reviewed the history of the applicant's earlier Flux Thimble Tube Inspection program, noting that in the early 1980's the applicant experienced a number of failures in its original flux thimble tubes, and in 1988 the applicant implemented flux thimble tube ECT in accordance with its original response to NRC Bulletin 88-09. The staff noted that in 1990 the applicant replaced all of its flux thimble tubes in Unit 1 and in Unit 2 with a new, wear-resistant thimble tube design consisting of an outer pressure boundary tube and a concentric dry guide path inner tube. The staff noted that in a letter dated December 20, 1993, the applicant submitted a supplemental response to NRC Bulletin 88-09 providing the staff with an evaluation of the new thimble tube design and justification for discontinuing its Flux Thimble Tube Inspection program. In a letter dated April 15, 1994, (Accession No: 9404220015) the staff issued a safety evaluation of the applicant's supplemental response to NRC Bulletin 88-09 accepting the applicant's proposal to discontinue the Flux Thimble Tube Inspection program.
During the audit the staff asked the applicant to clarify whether there had been any ECT of flux thimble tubes performed since issuance of the staff's safety evaluation dated April 15, 1994; whether there had been any replacement of flux thimble tubes since that date; and to explain how failure of a flux thimble tube's reactor coolant pressure boundary would be detected, if it should occur. In response to these questions, the applicant stated 1) that there had been no ECT of flux thimble tubes performed since issuance of the safety evaluation; 2) that some flux thimble tubes had been replaced, but not because of reactor coolant pressure boundary failure or failure caused by wear; and 3) that a leak detection system monitors any leakage from flux thimble tubes, and no such leakage had been observed since replacement of the original flux thimble tubes with the improved design.
During the audit of program elements 1-6, the staff found that:
Elements 1, 2, 3, 4, and 6 (scope of progr am, preventive actions, parameters monitored or inspected, detection of aging effects, and acceptance criteria) of the LRA AMP are consistent with the corresponding elements of the GALL Report AMP; and
Sufficient information was not available to determine whether element 5 (monitoring and trending) of the LRA AMP is consistent with the corresponding element of the GALL Report AMP.
In order to obtain the information necessary to verify whether LRA program element 5 is consistent with the corresponding element of the GALL Report AMP, the staff indicated that it would consider issuing an RAI for the following subject:
In element 5 of the LRA AMP the applicant's program basis document states that because there has been no examinations in several refueling outages due to
implementation of the improved flux thimble tube design, an examination will be conducted during the refueling outage prior to entering the period of extended operation to baseline the wall thickness and provide data for wear predictions. In the GALL Report AMP, element 5 states that wall thickness measurements will be trended and wear rates calculated, with examination frequency based on plant-specific wear projections, and that re-baselining of the examination frequency should be justified using plant-specific
wear-rate data unless prior plant-specific NRC acceptance for the re-baselining was received. It is not clear to the staff that these statements are consistent because the applicant has no current plant-specific wear rate data, and it is not clear to the staff how the applicant will re-baseline its current condition of flux thimble tube wear.
During the audit of program element 10 (operating experience), the staff found that:
The operating experience identified by the staff's independent database search and supplemented by the applicant is bounded by industry operating experience (i.e., no previously unknown aging effects were identified by the applicant or the staff); and
The operating experience identified by the staff's independent database search and supplemented by the applicant is sufficient to allow the staff to verify that the LRA AMP, as implemented by the applicant, is sufficient to detect and manage aging effects during the period of extended operation.
The staff also audited the description of the LRA AMP provided in the UFSAR Supplement, LRA Section A.2.1.25. The staff found this description to be consistent with the description provided in the SRP-LR and, therefore, acceptable.

LRA AMP B.2.1.28 ASME Section XI IWE
In the SNGS LRA, the applicant states that AMP XI.S1, "ASME Section XI, Subsection IWE" is an existing program with enhancements that is consistent with the program elements in GALL Report AMP XI.S1, "ASME Section XI, Subsection IWE." To verify this claim of consistency the staff audited the LRA AMP. This audit report considers program elements 1-6 (scope of
program, preventive actions, parameters monitored or inspected, detection of aging effects, monitoring and trending, and acceptance criteria) and program element 10 (operating experience) and the description of the program as contained in the UFSAR Supplement.
Program elements 7-9 (corrective actions, confirmation process, and administrative controls) are audited as part of the scoping and screening methodology audit. Issues identified but not resolved in this report are addressed in the SER.
The enhancements affect LRA program element 1 (scope of program). In Appendix A of the LRA, the applicant committed to implement these enhancements prior to the period of extended operation.
The first enhancement affects LRA program element 1 (scope of program). This enhancement expands on the existing program element by adding a requirement for inspection of a sample of the inaccessible liner covered by insulation and lagging prior to the period of extended operation and every ten years thereafter. Should unacceptable degradation be found, additional insulation will be removed as necessary to determine the extent of the condition in accordance with the corrective action process.
The second enhancement affects LRA program element 1 (scope of program). This enhancement expands on the existing program element by adding a requirement for visual inspection of 100% of the moisture barrier at the junction between the containment concrete floor and the containment liner. These inspections will be performed in accordance with ASME Section XI, Subsection IWE program requirements to the extent practical within the limitation of design, geometry and materials of construction of the components. The bottom edge of the stainless steel insulation lagging will be trimmed, if necessary, to perform the moisture barrier inspections. This inspection will be performed prior to the period of extended operation and on a frequency consistent with IWE inspection requirements thereafter. Should unacceptable degradation be found, corrective actions, including extent of condition, will be addressed in accordance with the corrective action process.
During its audit, the staff conducted walkdowns, interviewed the applicant's staff, and reviewed onsite documentation provided by the applicant. The staff also conducted an independent database search of the applicant's operating experience database using the keywords:

- 1. A review of the operating experience of the SNGS Unit 1 (PIRS # 950706252-78) in 1995, (Notification # 20344017) in 2007, and Unit 2 (Notification #20235636) in 2005, indicate that borated water has been flowing behind the liner plate which resulted in indications of corrosion of the containment liner plate and seepage of water into moisture barrier. Therefore, the staff plans to issue RAI requesting the applicant to provide detailed future plans for determining corrective actions, including commitments and completion schedules, for addressing steel liner plate corrosion and moisture barrier deterioration.
- 2. Program element 10 for the SNGS ASME Section XI, Subsection IWE AMP discusses sampling inspections of normally inaccessible areas of steel liner plate located behind the insulation panels around the lower 30 feet of the Unit 1 containment completed in 2009. Similar inspections are scheduled for Unit 2. However, details of the sampling methodology used for the inspection is not described in the LRA and program basis document. Therefore, the staff plans to issue an RAI to applicant to describe the sampling methodology used in 2009, and sampling methodology to be used in future inspections to select the locations for inspecting containment liner plate and moisture
barrier behind the insulating panels.
The staff also audited the description of the LRA AMP provided in the UFSAR Supplement. The staff found this description to be consistent with the description provided in the SRP-LR and, therefore, acceptable.

This audit report considers program elements 1-6 (scope of program, preventive actions, parameters monitored or inspected, detection of aging effects, monitoring and trending, and acceptance criteria) and program element 10 (operating experience) and the description of the program as contained in the UFSAR Supplement. Program elements 7-9 (corrective actions, confirmation process, and administrative controls) are audited as part of the scoping and screening methodology audit. Issues identified but not resolved in this report are addressed in the SER.
During its audit, the staff conducted walkdowns, interviewed the applicant's staff, and reviewed onsite documentation provided by the applicant. The staff also conducted an independent database search of the applicant's operating experience database using the keywords:
"IN 2009-04," "constant support," and "component support."
The table below lists the documents which were reviewed by the staff and were found relevant to the audit. These documents were provided by the applicant or were identified in the staff's search of the applicant's operating experience database.

Elements 1 through 6 (scope of program, preventive actions, parameters monitored or inspected, detection of aging effects, monitoring and trending, and acceptance criteria) of the LRA AMP were consistent with the corresponding elements of the GALL Report AMP.
During the audit of program element 10 (operating experience), the staff found that:
The operating experience provided by the applicant and identified by the staff's independent database search is bounded by industry operating experience (i.e., no previously unknown aging effects were identified by the applicant or the staff); and The operating experience provided by the applicant and identified by the staff's independent database search is sufficient to allow the staff to verify that the LRA AMP, as implemented by the applicant, is sufficient to detect and manage aging effects during the period of extended operation.
In order to obtain the information necessary to verify whether the applicant's operating experience supports the sufficiency of the LRA AMP, the staff indicated that it would consider issuing anRAI for the following subject:
GALL Program XI.M18, Bolting Integrity, states that GALL Program XI.S3, "ASME Section XI Subsection IWF," manages inspection of safety related bolting. SNGS station document SH-PBD-AMP-XI.M18 states that the Bolting Integrity AMP follows information as delineated in NUREG-1339, published EPRI NP-5769 guidelines, and industry recommendations. EPRI NP-5769, EPRI TR-104213, and NUREG-1339 recommend inspections for stress corrosion cracking (SCC) to prevent or mitigate degradation and failure of structural bolts with actual yield strength of 150,000 pounds per square inch. However, SNGS LRA Section 3.5.2 states that ASTM A490 bolts, with actual yield strength of 150,000 pounds per square inch, have high resistance to SCC due to their ductility and industry and plant specific operating experience have not identified SCC of ASTM A490 bolts as a concern. The staff will request the applicant to explain the basis for the conclusion that ASTM A490 bolts have resistance to SCC due to their ductility.
The staff also audited the description of the LRA AMP provided in the UFSAR Supplement. The staff found this description to be consistent with the description provided in the SRP-LR and, therefore, acceptable.
Based on this audit the staff:
Verified that LRA program elements 1-6 are consistent with corresponding program elements in the GALL Report AMP; Identified that additional information regarding operating experience is required before an indication regarding the sufficiency of the LRA AMP, as implemented by the applicant, to detect and manage aging can be reached; and Verified that the description provided in the UFSAR Supplement is an adequate description of the program.
In the SNGS LRA, the applicant states that AMP B2.1.31, "10 CFR Part 50, Appendix J," is an existing program that is consistent with the program elements in GALL Report AMP XI.S4, "10 CFR Part 50, Appendix J." To verify this claim of consistency the staff audited the LRA AMP.
This audit report considers program elements 1-6 (scope, preventive actions, parameters monitored or inspected, detection of aging effects, monitoring and trending, and acceptance criteria) and program element 10 (operating experience) and the description of the program as contained in the UFSAR Supplement.

During the audit, the staff found that: Elements 1-6 (scope of program, preventive ac tions, parameters monitored or inspected, detection of aging effects, monitoring and trending, and acceptance criteria) of the LRA AMP were consistent with the corresponding elements of the GALL Report AMP.
During the audit of program element 10 (operating experience), the staff found that:
The operating experience provided by the applicant and identified by the staff's independent database search is bounded by industry operating experience (i.e., no previously unknown aging effects were identified by the applicant or the staff); and
The operating experience provided by the applicant and identified by the staff's independent database search is sufficient to allow the staff to verify that the LRA AMP, as implemented by the applicant, is sufficient to detect and manage aging effects during the period of extended operation.
The LRA states that masonry walls have been systematically identified in accordance with the scoping and screening methodology and include those identified in response to IEB 80-11, USI A-46, and those that perform 10 CFR 54.4 intended functions. Actions taken include modifications of some walls, program enhancements, follow-up inspections to substantiate masonry wall analyses and classifications, and the development of procedures for tracking and recording changes to the walls. These actions addressed concerns raised by IEB 80-11 and IN 87-67, namely unanalyzed conditions, improper assumptions, improper classification, and lack of procedural controls. Operating experience is used to enhance plant programs, prevent repeat events, and prevent events that have occurred at other plants from occurring at SNGS. Operating experience from external and internal sources is utilized. SNGS Masonry Wall Program confirms that masonry walls are in good condition and show insignificant aging or degradation. Most recent structural monitoring inspections conducted in August 2008 for SNGS Unit 1 masonry walls indicated that no walls exhibited signs of significant degradation such as efflorescence or cracking. In 2006 corrective action reports were issued to document, evaluate, and repair: degraded masonry wall tie rod (missing nut) on the controlled facilities building wall; and degraded masonry blocks on a seismic radiation shielding masonry wall in the mechanical penetration room.
The staff also audited the description of the LRA AMP provided in the UFSAR Supplement. The staff found this description to be consistent with the description provided in the SRP-LR and, therefore, is acceptable.
Based on this audit the staff:
Verified that LRA program elements 1-6 are consistent with corresponding program elements in the GALL Report AMP; Verified that the operating experience is sufficient to indicate that the LRA AMP, as implemented by the applicant, is sufficient to detect and manage aging; and Verified that the description provided in the UFSAR Supplement is an adequate description of the program.
LRA AMP B.2.1.33 Structures Monitoring In the SNGS LRA, the applicant stated that AMP B2.1.33, "Structures Monitoring Program," is an existing program with enhancements that is consistent with the program elements in GALL AMP XI.S6, "Structures Monitoring Program." To verify this claim of consistency the staff audited the LRA AMP. This audit report considers program elements 1-6 (scope of program, preventative actions, parameters monitored or inspected, detection of aging effects, monitoring and trending, and acceptance criteria) and program element 10 (operating experience), and the description as contained in the UFSAR supplement. Program elements 7-9 (corrective actions, confirmation process, and administrative controls) are audited as part of the scoping and screening methodology audit. Issues identified but not resolved in this report are addressed in the SER.
The enhancements affect LRA program element 1 (scope of program), program element 3 (parameters monitored/measured), program element 4 (detection of aging effects), and program element 6 (acceptance criteria). In Appendix A of the LRA, the applicant committed to implement these enhancements prior to the period of extended operation.

During the onsite audit, the staff found that:
Elements 1, 2, 3, 5, and 6 (scope of progr am, preventive actions, parameters monitored or inspected, monitoring and trending, and acceptance criteria) of the LRA AMP were consistent with the corresponding elements of the GALL Report AMP; and
Sufficient information was not available to determine whether element 4 (detection of aging effects) of the LRA AMP was consistent with the corresponding element of the GALL Report AMP.
In order to obtain the information necessary to verify whether LRA program element 4 is consistent with the corresponding element of the GALL Report AMP, the staff indicated that it would consider issuing an RAI for the following subject:
Underground reinforced concrete structures and structures in contact with raw water at SNGS are subject to an aggressive environment with chloride levels up to 15,000 ppm that exceeds the GALL Report threshold limit for chlorides (< 500 ppm). The applicant stated during the onsite audit that inspection of below-grade structures will be performed only when exposed during plant excavations for construction or maintenance activities. In addition, service water intake structure will be monitored to provide a bounding condition and indicator of the likelihood of concrete degradation for inaccessible portions of concrete structures. It is not clear to the staff how the detection of aging effects will be adequately managed by the measures proposed by the applicant. Therefore, the staff plans to request the applicant to provide more details on how aging effects are detected in the inaccessible areas since groundwater intrusion has been observed through seismic expansion joints, concrete construction joints, and expansion and shrinkage cracks in the concrete.
During the onsite audit of program element 10 (operating experience), the staff found that:
The operating experience provided by the applicant and identified by the staff's independent database search is bounded by industry operating experience (i.e., no previously unknown aging effects were identified by the applicant or the staff); and The operating experience provided by the applicant and identified by the staff's independent database search is not sufficient to allow the staff to verify that the LRA AMP, as implemented by the applicant, is sufficient to detect and manage aging effects during the period of extended operation.
In order to obtain the information necessary to verify that the LRA AMP, as implemented by the applicant, is sufficient to detect and mange aging effects during the period of extended operation, the staff will consider issuing RAIs for the following subjects:
In the LRA it was noted that the spent fuel pools at SNGS have experienced leakage of borated water that has migrated through small cracks in the concrete to reach the seismic gap between the containment structure and fuel handling building, and in the Unit 1 Auxiliary Building mechanical penetration room. This leakage is still continuing even after the blockage in the leak chase channels was removed. The current rate of leakage thru leak chase channels is about 100 gallons per day. The staff plans to request additional information from the applicant about the effects of borated water leakage to the concrete or embedded steel reinforcement that is inaccessible for visual inspection.
The LRA states that leakage of borated water has occurred in SNGS Units 1 and 2 reactor cavities during refueling outages, but the leaks have been contained within the containment building. Therefore, the staff plans to request additional from the applicant to describe the plans for remedial actions or repairs to address leakage, and demonstrate that concrete and
embedded steel reinforcement potentially exposed to the borated water have not been degraded.
During the field walk down of SNGS, there were instances of efflorescence and evidence of groundwater penetration. At SNGS Unit 1 Auxiliary Building Elevation 64 (below ground water level), there was evidence of water in-leakage through the wall and the area was roped off as an exclusion zone. The applicant was asked about this and informed the staff that the source of the contamination was from in-leakage of groundwater and that the groundwater had picked up the contamination external to the wall. The staff plans to issue an RAI for the applicant to provide a plan to address the leakage of contaminated water through the reinforced concrete
wall.
The staff also audited the description of the LRA AMP provided in the UFSAR Supplement. The staff found this description to be consistent with the description provided in the SRP-LR and, therefore, is acceptable.
Based on this audit the staff:
Verified that with the enhancements most of the LRA program elements 1-6 are consistent with the corresponding program elements in the GALL Report; while identifying certain aspects of LRA program element 4 for which additional information or additional evaluation is required before consistency can be determined; Verified that the operating experience is not sufficient to indicate that the LRA AMP, as implemented by the applicant, is sufficient to detect and manage aging; and Verified that the description provided in the UFSAR Supplement is an adequate description of the program. LRA AMP B.2.1.34 Regulatory Guide 1.127 In the SNGS LRA, the applicant states that AMP B2.1.33, "Regulatory Guide 1.127, Inspection of Water-Control Structures Associated with Nuclear Power Plants," is an existing program with enhancement that is consistent with the program elements in GALL Report AMP XI.S7, "Regulatory Guide 1.127, Inspection of Water-Control Structures Associated with Nuclear Power Plants." To verify this claim of consistency the staff audited the LRA AMP. This audit report considers program elements 1-6 (scope of program, preventive actions, parameters monitored or inspected, detection of aging effects, monitoring and trending, and acceptance criteria) and program element 10 (operating experience) and the description of the program as contained in the UFSAR Supplement. Program elements 7-9 (corrective actions, confirmation process, and administrative controls) are audited as part of the scoping and screening methodology audit.
Issues identified but not resolved in this report are addressed in the SER.
Two enhancements affect LRA program element 3 (parameters monitored or inspected). The first enhancement expands on the existing program element by adding monitoring wooden components to include change in material properties and loss of material due to insect damage and moisture damage. The second enhancement expands the scope of elastomers inspection to include inspection for hardening, shrinkage and loss of strength due to weathering and degradation.
The next three enhancements affect LRA program element 4 (detection of aging effects). These enhancements expand on the existing program element by adding (1) requiring that inspection for submerged concrete structural components be performed by dewatering a pump bay or by a diver if the pump bay is not dewatered; (2) specifying an inspection frequency of not greater than five years for in-scope structures including submerged portions of the service water intake structure; and (3) requiring supplemental inspections of the in scope structures within 30 days following extreme environmental or natural phenomena (large floods, significant earthquakes, hurricanes, and tornadoes).
In Appendix A.5 of the LRA, the applicant committed to implement these enhancements prior to the period of extended operation.
During its audit, the staff conducted a walkdown of the SNGS service water intake structure, interviewed the applicant's staff, and reviewed onsite documentation provided by the applicant.
The visual inspection of the exterior portions of the water intake structure was very limited due to weather conditions and significant snow coverage.
