1Question and Answer Database Audit and Review Related to the License Renewal Application for James A. Fitzpatrick Nuclear Power plant No.Applicant'sRef. No.Audit QuestionsApplicant's ResponseProject Team's Evaluations150LRA Section B.1.1, "Program Description,"states that the program includes preventive measures to mitigate corrosion. Please discuss the specific preventive measures used at JAFNPP to mitigate corrosion of buried components, including the types of materials used for any coatings, wrappings, or linings.This program is a new program that will beconsistent with GALL AMP XI.M34 including the use of preventive measures such as coatings. The preventive measures used at JAFNPP include bituminous coatings such as coal tar epoxy or enamel that are applied in accordance with industry standards and site specifications.The project team finds the applicant'sresponse acceptable because the applicant's preventive measures to mitigate corrosion are consistent with GALL AMP XI.M34 recommendations. This question is resolved.251With regard to AMP B.1.1 described in LRASection B.1.1, please discuss a) the aggressiveness of the soil at the JAFNPP site as it relates to degradation of each of the material-environment combinations of the buried components identified, b) how soil aggressiveness is determined at JAFNPP, and c) the variation in soil aggressiveness at the different locations containing buried components on the JAFNPP site.Buried components at JAFNPP are coated withmaterials that were selected during original design and construction to provide protection from the potential adverse conditions of the soil (i.e.,
groundwater). The buried piping and tanks inspection program will perform inspections that will confirm that the buried components and their coatings are adequate to ensure that the components are able to perform their intended functions for the period of extended operation.For information concerning the aggressiveness ofground water, see the response to audit question
201.The project team finds the applicant'sresponse acceptable, because the applicant's approach (i.e., use of protective coating materials) is consistent with GALL AMP XI.M34 recommendations. Confirmation of effectiveness is the essence of this AMP.
The applicant has committed to conduct the inspections recommended in GALL AMP XI.M34. This question is resolved.352LRA Section B.1.1, "Program Description,"states that a focused inspection will be performed within the first ten years of the period of extended operation, unless an opportunistic inspection occurs within this ten-year period. Please confirm that an inspection, eitherfocused or opportunistic, will also be performed during the ten-year period immediately prior to entering the period of extended operation, as recommended in NUREG -1801. Also, please revise the FSAR supplement for AMP B.1.1 toAn inspection will be performed during the 10 yearperiod immediately prior to the period of extended operation. This point will be clarified by inserting the following after the third sentence of Section 3.1.B.4.b of JAF-RPT-05-LRD02."If an inspection did not occur, a focused inspectionwill be performed prior to the period of extended operation."The FSAR supplement for AMP 8.1.1 will beclarified to reflect this inspection.The project team finds the applicant'sresponse acceptable because the applicant amended the LRA in a letter dated February 01, 2007, to state that if an opportunistic inspection did not occur, a focused inspection will be performed prior to the period of extended operation in accordance with GALL Report recommendations. This question is resolved.
Question and Answer Database Audit and Review Related to the License Renewal Application for James A. Fitzpatrick Nuclear Power plant No.Applicant'sRef. No.Audit QuestionsApplicant's ResponseProject Team's Evaluations 2reflect this inspection.This requires a LRA amendment.454With regard to AMP B.1.1 described in LRASection B.1.1, please confirm that any coating and wrapping degradations are reported and evaluated according to site corrective actions procedures in accordance with 10 CFR 50, Appendix B.As stated in section B.1.1 of the LRA this program isconsistent with GALL. In addition, section 3.1.B.7.b of JAF-RPT-05-LRD02 states that the site corrective action program is in accordance with 10 CFR 50 Appendix B such that any coating or wrapping degradations would be reported. The project team finds the applicant'sresponse acceptable because coating and wrapping degradations are reported and evaluated in accordance with 10 CFR 50, Appendix B corrective action program .
This question is resolved.555LRA Section B.1.1, Exceptions to NUREG-1801, states that methods that allow assessment of pipe condition without excavation may be substituted for inspections requiring excavation solely for the purpose of inspection. Phased array UT technology is provided as an example of such a method. If phased array UT is used, please discuss the following with regard to this exception: a) how will the method be qualified, b) what training will inspectors be given, c) what criteria will be used to determine if corrective actions are needed, and d) what information will be provided related to the condition of coatings, linings, or wraps used on the buried components.The criteria will be that the inspection methodallows effective assessment of piping condition without the threat of damage to the coating that accompanies excavation. It is anticipated that such methods will allow for assessment of more extensive portions of buried piping than the method of excavating for visual inspections at a sampling of locations. This exception was to allow the use of more effective state-of-the-art inspection techniques, such as phased array UT, in lieu of excavating piping which has the potential for damaging the piping and its coating. Any technique used will be appropriately qualified for use and will require the use of trained inspectors applying appropriate acceptance criteria. The specific acceptance criteria and the extent of information providing an indication of the condition of the coating will depend on the specific inspection method developed. The effectiveness of the method in determining the overall condition of the piping and its protective coating will be the determining factor in the selection of alternate methods, if any.The following applies to the use of the phasedarray UT method of inspection for inspection of buried piping and tanks.The project team finds the applicant'sresponse acceptable, because any technique that is substituted for excavation/visual inspection will require formal demonstration of the adequacy of the technique to detect and characterize degraded conditions, and must be conducted by NDE inspectors qualified to Level II in the specific technique employed.The effectiveness of the method indetermining the overall condition of the piping and its protective coating will be the determining factor in the selection of alternate methods, if any.This question is resolved.
Question and Answer Database Audit and Review Related to the License Renewal Application for James A. Fitzpatrick Nuclear Power plant No.Applicant'sRef. No.Audit QuestionsApplicant's ResponseProject Team's Evaluations 3A. How will the method be qualified? The methodof qualification for a specific UT technique will be through demonstration. This will be completed utilizing the guide lines established in ASME Sec.
V and any additional industry guidance that has been established at the time of qualification.B. What training will inspectors be given? Theminimum training requirements for inspectors performing / interpreting examination results will be that of a Level II. This will be in accordance with Entergy Nuclear Northeast's nondestructive testing written practice.C. What criteria will be used to determine ifcorrective actions are needed? The piping examined will be evaluated utilizing existing Engineering procedures and specifications.
Corrective actions will be through the normal JAFNPP correction action process.D. What information will be provided related to thecondition of coatings, linings, or wraps used on the buried components? The ability to determine the condition of an exterior coating, lining, or wrap will not be known until the technique has been demonstrated. If ascertaining the condition of this material is considered an essential variable of the examination, the use of multiple test methods may be necessary to obtain the required results.657The FSAR supplement for AMP B.1.1 InSection A.2.1 of the LRA does not include a discussion of the commitment to implement this new program prior to the period of extended operation. Please revise the FSAR supplement to include this commitment.Section A.2.1 of the LRA states, "All agingmanagement programs will be implemented prior to entering the period of extended operation." For additional clarification, LRA Appendix A will be revised as follows.The project team finds the applicant'sresponse acceptable because the applicant amended Section A.2.1 of the LRA to include a discussion of the commitment to implement this new program prior to the period of extended Question and Answer Database Audit and Review Related to the License Renewal Application for James A. Fitzpatrick Nuclear Power plant No.Applicant'sRef.

This requires a LRA Amendment.operation. See amendment letter No. 5,dated February 01, 2007. This question is resolved.758The "Program Description" for AMP B.1.9states that the program entails sampling to ensure that adequate diesel fuel quality is maintained to prevent corrosion of fuel systems. Please provide the sampling frequency for each of the diesel fuel tanks in the scope of license renewal.The EDG fuel oil storage tanks are sampled every31 days. The diesel fire pump fuel oil tanks are sampled every 92 days.Reference procedure SP-01.07, "Diesel Fuel oilSampling and Analysis", step 2.3.1:The project team finds the applicant'sresponse acceptable because the fuel oil sampling frequency is consistent with GALL AMP XI.M30, industry standards, and the plant Technical Specifications.
The staff confirmed that the EDG fuel oil storage tanks are sampled every 31 days, and the diesel fire pump fuel oil tanks are sampled every 92 days, in accordance with procedure SP-01.07, "Diesel Fuel Oil Sampling and Analysis," Revision 7. The staff also verified that these sampling frequencies are consistent with current industry standards, and are in accordance with the plant's Technical Specifications.
On this basis, the staff finds these sampling frequencies acceptable861With regard to AMP B.1.9, please confirm thataccumulated water is periodically drained from each of the diesel fuel tanks in the scope of license renewal and provide the frequency at which this activity is performed. If it is not, please provide the technical justification for not draining accumulated water periodically from each tank.As stated in LRA Section B.1.9 under"Enhancements", the Diesel Fuel Monitoring Program will be enhanced to include periodic draining. The diesel fuel oil tanks are sampled monthly for water. If water is detected then it is drained. Site procedure reference is ST-9J.The project team finds the applicant'sresponse acceptable because the Diesel Fuel Monitoring Program will be enhanced to include routine draining, cleaning, visual inspections, and ultrasonic measurement of the bottom surfaces of the diesel fuel tanks. The frequency for draining, cleaning and inspecting the tanks will be based on past experience, which has been demonstrated to provide acceptable performance for the diesel fuel storage tanks. With this enhancement, the Diesel Fuel Monitoring Program will be consistent with GALL AMP XI.M30. This question is Question and Answer Database Audit and Review Related to the License Renewal Application for James A. Fitzpatrick Nuclear Power plant No.Applicant'sRef. No.Audit QuestionsApplicant's ResponseProject Team's Evaluations 5resolved.962With regard to AMP B.1.9, please clarifywhether coatings are used on any of the diesel fuel tanks in the scope of license renewal.
Please include the type of coating, if any, and the results of any recent inspections of the coating.Coatings are not used on the diesel fuel tanks inthe scope of license renewal.The project team finds the applicant'sresponse acceptable because the coating is not used on the diesel tanks and is not credited for aging management. This question is resolved.1063With regard to AMP B.1.9, please confirm thatmulti-level oil sampling and analysis are performed for the diesel fuel oil storage tank in accordance with ASTM Standard D 4057. If it is not, please provide the technical justification for not performing multi-level sampling.JAFNPP performs periodic multilevel sampling toprovide assurance that fuel oil contaminants are within acceptable limits. ASTM D4057, Standard Practice for Manual Sampling of Petroleum and Petroleum Products, is used for guidance on oil sampling. The JAF procedure is SP-01.07.The project team finds the applicant'sresponse acceptable because the applicant's Diesel Fuel Monitoring Program includes sampling and analysis activities that are in accordance with ASTM standard D4057 and is consistent with GALL AMP.XI.M30 recommendations. This question is resolved.1164With regard to AMP B.1.9, please provide thefrequency at which water and biological activity or particulate contamination concentrations are monitored and trended for each of the diesel fuel tanks in the scope of license renewal.The monitoring and trending attribute of NUREG-1801,Section XI.M30, Fuel Oil Chemistry Program states water and biological activity or particulate contamination concentrations are monitored and trended in accordance with the plant's technical specifications or at least quarterly. As indicated in the LRA, no exceptions are taken with respect to the monitoring and trending attribute of the program described in NUREG-1801,Section XI.M30. The EDG fuel oil storage tanks are sampled every31 days. The diesel fire pump fuel oil tanks are sampled every 92 days. These samples include a Tech Spec required composite for particulates on the diesel fuel oil storage tanks. The samples also include a test for water and sediment required by the Technical Requirements Manual.The project team finds the applicant'sresponse acceptable because the fuel oil chemistry requirements are implemented in accordance with plant Technical Requirements Manual(TRM) and technical specification (TS) 5.5.10 and because the audit team determined that the fuel oil testing performed in accordance with the standards specified in TS 5.5.10 and the applicant's TRM would be sufficient to test the oil for water and sediment contents, particulate contents, oil flash point property, and oil kinematic viscosity property. Thus, the testing under TS 5.5.10 and the TRM will accomplish the type of diesel fuel oil testing recommended in GALL AMP XI.M30 for Question and Answer Database Audit and Review Related to the License Renewal Application for James A. Fitzpatrick Nuclear Power plant No.Applicant'sRef. No.Audit QuestionsApplicant's ResponseProject Team's Evaluations 6implementation. This question is resolved.1265The Operating Experience section for AMPB.1.9 states that in 2000, sample results for EDG fuel oil storage tanks exceeded the industry acceptable limit for particulate contamination. Please discuss the extent and cause of this excursion and the corrective actions.The probable cause was listed as possible fuel oildegradation. The extent affected tanks TK-6B and TK-6D. Corrective actions included resampling tank TK-6B and draining and refilling tank TK-6D with fresh fuel oil. Resample results of TK-6B were acceptable. Reference document, CR-JAF-2000-02022 and CR-JAF-2000-05845The project team finds the applicant'sresponse acceptable because the extent and cause of the excursion and the corrective actions taken were found to be fully documented in the applicant's corrective action program. This question is resolved.1366The Operating Experience section for AMPB.1.9 states that in 2002, trending of bottom sample results for EDG fuel oil storage tank 93TK-6C showed a particulate contamination increase. Please discuss the extent and cause of this excursion.The probable cause was listed as fuel oildegradation. Corrective action was to drain 2000 gallons of fuel oil from the bottom of the tank and refill the tank with fresh fuel oil Reference document, CR-JAF-2002-01207.The project team finds the applicant'sresponse acceptable because the cause of the excursion and the corrective actions taken were found to be fully documented in the applicant's corrective action program. This question is resolved.1467The Exception noted for AMP B.1.9 states thatthe guidelines of ASTM D2276 are not used for determination of particulates; instead ASTM D6217 is used. However, NUREG-1801, Rev.
1, includes ASTM D6217 as an acceptable standard for the determination of particulates.
Please clarify why the use of ASTM D6217 was identified as an exception.The NUREG-1801 Section XI.M30 ParametersMonitored/Inspected states, "For determination of particulates, modified ASTM D 2276, Method A, is used.". The guidelines of ASTM D2276 are not used for determination of particulates, so it was necessary to identify this as an exception.The project team finds the applicant'sresponse acceptable because although GALL AMP XI.M30 recommends use of the modified ASTM Standard D 2276 for the measurement of particulates in diesel fuel, Standard D6217 is more appropriate for middle distillate fuels used at JAFNPP.
The project team verified that the use of ASTM standard D 6217 is consistent with the requirements in the plant technical specifications. This question is resolved.1568The Enhancement noted for AMP B.1.9 statesthat the Diesel Fuel Monitoring Program will be enhanced to include periodic draining, cleaning, visual inspections, and ultrasonic measurement of the bottom surfaces of the fire pump diesel fuel oil tanks, EDG day tanks, and EDG fuel oilThe emergency diesel underground fuel oil storagetanks are cleaned and inspected on an eight year frequency. They were UT inspected in 1988. These inspections have not revealed any degradation in the surface of the tank. As described in XI.M34 the most susceptible area for corrosion is the bottom ofThe project team finds the applicant'sresponse acceptable because the frequency for draining, cleaning and inspecting the tanks will be based on past experience, which has been demonstrated to provide acceptable performance for the Question and Answer Database Audit and Review Related to the License Renewal Application for James A. Fitzpatrick Nuclear Power plant No.Applicant'sRef. No.Audit QuestionsApplicant's ResponseProject Team's Evaluations 7storage tanks. Please provide a) the frequencyfor these activities for each diesel fuel tank in the scope of license renewal, b) the basis for each frequency, and c) how the locations for UT measurements will be determined.the tanks where water and sediment canaccumulate. JAFNPP plans to continue to inspect these tanks on this eight year frequency based on past inspection results and if any significant corrosion is detected a UT of the corrosion site and adjacent areas of the tank bottom will be performed using the appropriate grid size based on the size of the tank.The fire pump diesel fuel oil tanks and the EDGday tanks are not currently subjected to internal inspections. An inspection frequency cannot be firmly established until the internal condition of these tanks is baselined. JAFNPP therefore plans to inspect these tanks on an eight year frequency similar to the EDG underground storage tanks. This frequency is based on the past inspection results of the EDG underground fuel oil storage tanks which have not indicated significant degradation while exposed to the same internal fuel oil environment.
If initial inspections find unexpected conditions the frequency will be adjusted via the corrective action process.diesel fuel storage tanks. Ultrasonicmeasurement of the tank bottoms will provide objective evidence that degradation of the tanks is not occurring.
With the enhancement, the Diesel Fuel Monitoring Program will be consistent with GALL AMP XI.M30. This question is resolved.1669Section B.1.9 of the LRA states twoenhancements for AMP B.1.9; however, the FSAR supplement in Section A.2.1.9 of the LRA does not include a discussion of the commitment to enhance this program. Please revise the FSAR supplement to include a discussion of the two enhancements for AMP B.1.9 to be implemented prior to the period of extended operation.Section A.2.1 of the LRA states, "All agingmanagement programs will be implemented prior to entering the period of extended operation." This includes enhancements to individual programs. For additional clarification, LRA Appendix A will be revised as follows.Section A.2.1.9, Diesel Fuel Monitoring Program, add "This program will be enhanced to include periodic draining, cleaning, and ultrasonic measurement of the bottom surfaces of the fire pump diesel fuel oil tanks, EDG day tanks, and EDG fuel oil storageThe project team finds the applicant'sresponse acceptable because the applicant committed to amend LRA Section A.2.1 to clearly state that the program will be enhanced to include periodic draining, cleaning, and ultrasonic measurement of the bottom surfaces of the fire pump diesel fuel oil tanks, EDG day tanks, and EDG fuel oil storage tanks and to specify acceptance criteria for UT measurements of diesel fuel storage tanks included in this program.

This question is resolved.1770With regard to AMP B.1.9, please clarifywhether flashpoint is measured as part of the fuel oil analysis. If it is not measured, please provide the technical justification for not measuring this parameter.Flashpoint is not a required parameter for thisAMP. NUREG-1801 Section XI.M30 does not specify flash point as a test for diesel fuel oil.
However, flash point is measured. Reference procedure SP-01.07, "Diesel Fuel oil Sampling and Analysis", step 3.1.2.A:
Flash Point - °F 125 °F - minFlash points are measured on both new and storeddiesel fuel oil.The project team finds the applicant'sresponse acceptable because although NUREG-1801 Section XI.M30 does not specify flash point as a required test parameter for this AMP , the project team confirmed that it is monitored under the current fuel oil analysis program in accordance with procedure SP-01.07, "Diesel Fuel oil Sampling and Analysis".
This question is resolved.1871Clarify whether or not the inspections and/orsurveillance tests requirements described in this AMP are consistent with Technical Specifications (TS) Sections 3.0.2, 3.0.3, 3.8.3.3 and 5.5.10. If not, provide a technical basis for its acceptability and your commitments for revising the TS.The inspections and/or surveillance testrequirements described in this AMP are consistent with Technical Specifications (TS).Reference procedure SP-01.07, "Diesel Fuel oilSampling and Analysis", step 3.1.1.The project team finds the applicant'sresponse acceptable because the team confirmed that the inspection and surveillance test requirements are consistent with the plant TS and GALL AMP XI.M30 recommendations. This question is resolved.1973In LRA Section B.1.21, the ProgramDescription states that the one-time inspection activity for small bore piping in the reactor coolant system and associated systems that form the reactor coolant pressure boundary will also be comparable to the program described in NUREG-1801,Section XI.M35, One-TimeJAFNPP meets the requirements of ASME SectionXI with respect to the inspection of Class 1 small bore piping and socket welds through implementation of a risk-informed ISI program.
During the period of extended operation, as required by 10 CFR 50.55a, JAFNPP will meet the requirements of ASME Section XI or implement anThe current NRC position in GALL forinservice inspection of small bore piping is to perform volumetric examination of welds at selected critical locations susceptible to cracking, in addition to the ASME Section XI requirements.

Please clarify if JAFNPP meets the requirements of ASME Section XI with respect to the inspection of Class 1 small bore piping and socket welds.approved alternative such as the existing risk-informed ISI Program.The ISI program for small-bore piping at JAF usesnondestructive examination (NDE) techniques to detect and characterize flaws. Three different types of examinations are volumetric, surface, and visual.
Examinations performed on pipe segments within the 3rd interval inspection program have included the examination of associated socket welds. The pipe segments have been examined for FAC and thermal fatigue by ultrasonic's, radiography and surface examination (dependent upon flaw mechanism) that captures the associated socket welds verifying integrity.
Surface examinations, such as magnetic particle or dye penetrant testing, are used to locate surface flaws.Three levels of visual examinations are specified.VT-1 visual examination is conducted to assess the condition of the surface of the part being examined, looking for cracks and symptoms of wear,corrosion, erosion or physical damage. It can be done with either direct visual observation or with remote examination using various optical and video devices. VT-2 visual examination is conducted specifically to locate evidence of leakage from pressure retaining components (periodic pressure tests). While the system is under pressure for a leakage test, visual examinations are conducted to detect direct or indirect indication of leakage. VT-3 visual examination is conducted to determine general mechanical and structural condition of components and supports and to detected discontinuities and imperfections.the ASME Section XI requirements. However, Subsection IWB Code requirements for both small bore welds and socket weld connections include surface examinations and VT-2 examinations for leakage during pressure testing of the RCPB piping.JAFNPP states in its response that duringthe period of extended operation, as required by 10 CFR 50.55a, JAFNPP will meet the requirements of ASME Section XI or implement an approved alternative such as the existing risk-informed ISI Program. In addition, the ISI program for small-bore piping at JAF uses nondestructive examination (NDE) techniques to detect and characterize flaws. In LRA Section B.1.21, the ProgramDescription also states that the one-timeinspection activity for small bore piping inthe reactor coolant system and associatedsystems that form the reactor coolantpressure boundary will also becomparable to the program described inNUREG-1801,Section XI.M35, One-TimeInspection of ASME Code Class I Small-Bore Piping. The project team finds that the applicant'sresponse acceptable because the onetime inspection program for small borepiping will meet the current NRC positionsand therefore, adequately managecracking during the period of extendedoperation. This question is resolved.
Question and Answer Database Audit and Review Related to the License Renewal Application for James A. Fitzpatrick Nuclear Power plant No.Applicant'sRef. No.Audit QuestionsApplicant's ResponseProject Team's Evaluations 10A preliminary review of Class 1 piping wasperformed to derive an estimated number of Class 1 socket welds and/or piping segments in accordance with the Risk-Informed Inservice Inspection Program (RI-ISI). The estimated total of Class 1 socket welds and/or piping segments is eight piping segments that are inspected in each ISI interval out of the total segments identified in the ISI program and includes approximately 15 welds out of the total class I socket weld population. The total number of inspections conducted duringthe 3rd ISI Interval estimated at approximately 5%
of the total segments and 1% of the total welds
.Examination Category B-F welds are scheduled and examined as part of the IGSCC Augmented Inspection Program. Extent and frequency of examinations are in accordance with the Risk-Informed ISI Program.2083The FSAR supplement for AMP B.1.21 inSection A.2.1.23 of the LRA does not discuss the commitment to implement this new program prior to the period of extended operation.
Please revise the FSAR supplement to discuss this commitment.Section A.2.1 of the LRA states, "All agingmanagement programs will be implemented prior to entering the period of extended operation." This includes the One-Time Inspection Program. For additional clarification, LRA Appendix A will be revised as follows.Section A.2.1.23, One-Time Inspection Program,add"This program will be implemented within the 10 years prior to the period of extended operation."
This requires a LRA amendment.The project team finds the applicant'sresponse acceptable because the applicant amended LRA Section A.2.1.23 to include a discussion to implement this new program prior to the period of extended operation. See amendment letter No. 5, dated February 01, 2007. This question is resolved.2186In LRA Section B.1.22, the table in the ProgramDescription states that this AMP will be used to manage loss of material for carbon steel components on cranes, rails, and girders.Reactor building steel crane structural girders usedin load handling are inspected under the Periodic Surveillance and Preventive Maintenance Program (PSPM) identified in Section B.1.22 of theThe project team finds the applicant'sresponse acceptable because the aging management activities for crane rails and girders will involve visual examination Question and Answer Database Audit and Review Related to the License Renewal Application for James A.

Similar statements are made for the HPCI system and RCIC system piping. Please clarify the intent of these statements. Specifically, are these components in the scope of this AMP or the flow accelerated corrosion AMP?The intent of these statements was to explain thatthe core spray, HPCI and RCIC piping included in this program are administratively controlled in the Flow Accelerated Corrosion program, but are inspected using the Periodic Surveillance and Preventive Maintenance program. Because the aging effect for these components is loss of material due to erosion and not loss of material due to flow accelerated corrosion it would not be appropriate to manage using the Flow Accelerated Corrosion program. Therefore these components are managed by thePeriodic Surveillance and Preventive Maintenance program.Section A.2.1 of the LRA states, "All agingmanagement programs will be implemented prior to entering the period of extended operation." This includes enhancements to individual programs.The project team finds the applicant'sresponse acceptable because the Periodic Surveillance and Preventive Maintenance program is adequate to manage the aging effect for these components due to erosion.
This question is resolved.2490The FSAR supplement for AMP B.1.22 inSection A.2.1.24 of the LRA does not discuss the commitment to implement the enhancement to this program prior to the period of extended operation. Please revise the FSAR supplement to discuss this commitment.For additional clarification, LRA Appendix A will berevised as follows.Section A.2.1.24, Periodic Surveillance andPreventative Maintenance Program, add "This program will be enhanced as necessary to assurethat the effects of aging will be managed such that applicable components will continue to perform their intended functions consistent with the current licensing basis. These enhancements will be implemented prior to the period of extended operation." This requires a LRA amendment.The project team finds the applicant'sresponse acceptable because the applicant amended LRA Section A.2.1.24 to discuss the enhancement to this program prior to the period of extended operation.

This question is resolved. 2894The discussion of Exceptions to NUREG-1801for AMP B.1.2 in the LRA states that liquid penetrant testing (PT) of CRDRL nozzle blend radius, adjacent wall area and bore regions is not performed. Note 3 states that JAFNPP performs EVT-1 visual examinations (1/2 mil resolution) of the CRDRL nozzle blend radius and adjacent wall area every 10 years in lieu of PT examinations. Note 3 further states that the weld overlay installed over a crack in the CRDRL nozzle-to-cap weld covers the nozzle, the nozzle-to-cap weld, and part of the cap.
Since the weld overlay is examined using UT in accordance with GL 88-01 and BWRVIP 75-A, the LRA concludes that examination of the nozzle and original nozzle-to-cap weld is not required. In NUREG-1801, AMP XI.M6 recommends PT inspection of CRDRL nozzle blend radius and bore regions, and the reactor vessel wall area beneath the nozzle. Please provide a discussion, including drawings, to clarify how UT inspection of the weld overlay is consistent with the recommendations in NUREG-1801.

The staff notes that the Electrochemical Corrosion Potential (ECP) quantifies the oxidizing power of a solution in contact with a specific metal surface. The ECP of different reactor internals component materials is very sensitive to the concentration of oxygen, hydrogen, and hydrogen peroxide and therefore is different at different locationsBased on the BWRVIP radiolysis model, ameasured molar ratio in the reactor water of > 2:1 demonstrates the molar ratio is > 2:1 everywhere in the reactor vessel at or below the normal water level which is where all the wetted components were treated with noble metals. JAFNPP adds sufficient feedwater hydrogen to operate with a measured molar ratio > 4:1. In accordance with the model, it demonstrates at least a molar ratio of 3:1 at the upper portion of the shroud OD. Components above this level cannot be mitigated with HWC or NMCA. When molar ratio is > 2:1 the equivalent of ECP according to the model is < -400 mV SHE.

Operating experience shows that this program has been effective in managing aging effects. Therefore, continued implementation of the program provides reasonable assurance that effects of aging will be managed so that components crediting this program can perform their intended function consistent with the current licensing basis during the period of extended operation. In addition, as described in LRA Section B.1.21, prior to the period of extended operation, a one-time inspection activity will verify the effectiveness of the water chemistry control aging management programs by confirming that unacceptable cracking, loss of material, and fouling is not occurring.58126Flow accelerated corrosion (FAC) in carbonand low alloy steel components is affected by dissolved oxygen concentration, among other factors. Section 4.2.1 of BWRVIP-130 states that the rate of FAC increases dramatically if oxygen concentration is less than about 25 ppb. Please describe the procedures used at JAFNPP to maintain appropriate oxygen levels in water in the various plant systems for which this AMP is credited to mitigate loss of material due to FAC (i.e., erosion/corrosion, steam cutting, etc.).The Water Chemistry Control - BWR Program isnot credited to manage loss of material due to FAC. Consistent with NUREG-1801, loss of material due to FAC is managed by the Flow-Accelerated Corrosion Program described in LRA Section B.1.14. As stated in NUREG-1801,Section XI.M17, the FAC program is an analysis, inspection, and verification program; thus, there is no preventive action.

As described in NUREG-1801, Rev. 1,Section XI.M21, CCCW system aging management programs monitor the effects of corrosion and SCC by testing and inspection. Please describe the testing and inspection activities utilized at JAFNPP to monitor the effects of corrosion and SCC on closed cooling water systems components.As noted in LRA section B.1.29.3, the JAFNPPWater Chemistry Control - Closed Cooling Water Program takes exception to the recommended performance and functional testing, with the following justification.While NUREG-1801,Section XI.M21, Closed-CycleCooling Water System endorses EPRI report TR-107396 for performance and functional testing guidance, EPRI report TR-107396 does not recommend that equipment performance and functional testing be part of a water chemistry control program. This is appropriate since monitoring pump performance parameters is of little value in managing effects of aging on long-lived, passive CCW system components. Rather, EPRI report TR-107396 states in section 5.7 (Section 8.4 in EPRI report 1007820) that performance monitoring is typically part of an engineering program, which would not be part of water chemistry. In most cases, functional and performance testing verifies that component active functions can be accomplished and as such would be governed by the maintenance rule (10 CFR 50.65). For example, loss of material cannot be detected by system performance testing. Passive intended functions of pumps, heat exchangers and other components will be adequately managed by the Closed Cooling Water Chemistry and One-Time Inspection programs through monitoring and control of water chemistry parameters and verification of the absence of aging effects.The project team finds the applicant'sresponse acceptable because the applicant clarified that the program is based on EPRI Report TR-1007820 (Revision 1 to EPRI TR-107396). From a review of the EPRI report the project team confirmed that the report does not recommend that performance and functional testing be part of the water chemistry control program. The lack of performance and functional testing, however, is not consistent with GALL.
The applicant has taken an exception to the GALL Report program elements "parameters monitored or inspected," and "detection of aging effects and has provided an adequate technical basis to support this exception. This question is resolved.

This is appropriate since monitoring pump performance parameters is of little value in managing effects of aging on long-lived, passive CCW system components. Rather, EPRI report TR-107396 states in section 5.7 (Section 8.4 in EPRI report 1007820) that performance monitoring is typically part of an engineering program, which would not be part of water chemistry. In most cases, functional and performance testing verifies that component active functions can be accomplished and as such would be governed by the maintenance rule (10 CFR 50.65). For example, loss of material cannot be detected by system performance testing. Passive intended functions of pumps, heat exchangers and other components will be adequately managed by the Closed Cooling Water Chemistry and One-Time Inspection programs through monitoring and control of water chemistry parameters and verification of the absence of aging effects.In addition, LRA section B.1.21, One-TimeInspection, describes inspections planned to verify effectiveness of the water chemistry control programs to ensure that significant degradation is not occurring and component intended function is maintained during the period of extended operation.As described in LRA section B.0.3, JAFNPP qualityassurance (QA) procedures, review and approval processes, and administrative controls are implemented in accordance with the requirements of 10 CFR Part 50, Appendix B.

This requires a LRA Amendment.107179In LRA Section B.1.15, the ProgramDescription states that representative tubes within the sample population of heat exchangers will be eddy current tested at a frequency determined by internal and external operating experience. Please clarify what is meant by internal and external operating experience. Also, please discuss a) the rational to be used in determining the inspection frequency using plant-specific and industry operating experience, and b) the anticipated minimum inspection frequency to be imposed to ensure timely detection of aging effects."Internal and external operating experience" means"JAFNPP site and industry operating experience."
The following is an example of the steps which may be used to develop the inspection plan:
- 1. An initial visual inspection would be performed of the sample population of in scope heat exchangers. This inspection would document the "as-found" conditions. Additional examination methods may be used if "as-found" conditions warrant, (i.e. ultrasonic thickness measurements or radiography). The results of these inspections would be used to establish the frequency of future inspections.
- 2. Where physically accessible, baseline eddy current data would be obtained. The results of these tests would be used to determine the frequency of future inspections and the number of tubes to be sampled.The project team finds the applicant'sresponse acceptable because the inspection plan for heat exchangers will specify the inspection frequency based on baseline testing and plant-specific and industry operating experience. This question is resolved.108180In LRA Section B.1.15, the discussion of"Parameters Monitored" program element states that, where practical, eddy current inspections of shell-and-tube heat exchanger tubes will be performed to determine tube wall thickness. Please discuss the criteria for determining practicality for eddy current inspections. Also, please discuss how aging of tubes for heat exchangers in the scope of this AMP will be managed when it is determined that eddy current inspection is impractical.(a) Practicality is dependant on physical location,physical size, orientation, physical dimensions, accessibility and disassembly of heat exchanger.(b) If eddy current inspection is determined to beimpractical aging of tube is managed based on the results of:1.

Thistask is focused on finding leaks in cracked tubes and in defects at the tube joints. These defects may be caused by improperinstallation, abusive transients, by plugging of tubes, and also by improper cleaning in the case of rolled tube joints.joints. Visual inspections of heatexchanger components with the same material/ environment combination as the tubes will also provide information that can be used to determine if degradation is occurring, and whether further action is needed to manage aging. This question is resolved.109181In LRA Section B.1.15, the discussion of"Parameters Monitored" program element states that visual inspections will be performed on heat exchanger heads, covers, and tubesheets where accessible to monitor surface condition for indications of loss of material.
Since this AMP is credited to manage loss of material-wear on the external surface of heat exchanger tubes, please clarify how the visual inspections described will help to manage the aging effects for which it is credited in the LRA.Visual inspections is focused on detecting theextent of tube erosion, corrosion, fouling and scaling, and on the detection of corrosion at the tube sheet and rolled tube joints. In some cases, heat exchanger heads, partition plates, baffles, covers, or tubesheets are of the same material environment combination as tubes, which provides additional data for determining inspection frequency and the presence of aging effects.The project team finds the applicant'sresponse acceptable because the heat exchangers within the scope of this program s have tubes constructed of copper alloy that are exposed to lube oil or treated water on the external surface. The aging effect of concern for these components is loss of material due to wear. The applicant has clarified that eddy current testing will be performed when practical. For cases where eddy current inspection is determined to be impractical, aging of the heat exchanger tubes will be managed using visual inspection of the external portion of heat exchanger tubes.
Visual inspections are conducted during maintenance activities and are focused on detecting the presence and extent of a loss of material. Based on its review, the project team has determined that the applicant's use of wall thickness via eddy current testing, or indications of loss of material via visual inspection as the parameters to be monitored will provide an effective method of detecting degradation of heat exchanger tubes.

This ensures that potential impacts of different design, material and environment combinations will be addressed.(b) Representative tubes within the heat exchangersample population will be selected based on previous eddy current inspections, WO history such as corrective maintenance, tube plugging history, engineering evaluation, EPRI guidance and service condition of the heat exchanger. The sample tubes are considered on locations in the bundle most prone to discovering mechanistic failures such as pitting, tube erosion, and lagging vibration wear/fret damage.The project team finds the applicant'sresponse acceptable because at least one heat exchanger of each type, material, and environment combination will be included in the sample population. This ensures that potential impacts of different design, material and environment combinations will be addressed.
Representative tubes within the heat exchanger sample population will be selected based on previous eddy current inspections, work order history, such as corrective maintenance, tube plugging history, engineering evaluation, EPRI guidance, and service conditions of the heat exchanger. The applicant's rational for sample selection provides assurance that the leading indicators of degradation will be inspected. This question is resolved.111183In LRA Section B.1.15, the discussion of"Detection of Aging Effects" program element states that representative tubes within the sample population of heat exchangers will be eddy current tested. Please discuss the data collection techniques that will be implemented for this AMP.Eddy Current test inspections are done accordingto the code requirements of ASME Section V, Article 8, 1980 and 1989 editions. Vendor who provides services uses digital data acquisition with offline analysis.The project team finds the applicant'sresponse acceptable because eddy current test inspections are done in accordance with established industry standards (ASME Section V, Article 8, 1980 and 1989 editions).

Judgment of the engineering team (twominimum) is used to evaluate degradation and determine the course of action whether to restore the condition of the structure or to adjust the monitoring frequency. The results of each subsequent monitoring inspection are recorded and evaluated to establish the time for the next inspection. The interval before the next inspection for a structure may decrease, increase, or remain the same based on the condition of the structure relative to the previous inspection. A Condition Report (CR) is issued for any structures that require immediate attention or a Work Order is initiated for minor degradation that requires attention. Inspection Checklist data sheets from the most recent inspections are available for review.
The following reinforced concrete and masonry degradations, including cra cks and gaps, werereported during the 2005 SMP inspections:The SMP inspection of the RWCU Heat Exchanger(Inspection # 05-RB-300-005-03) reinforced concrete pedestal foundation monitors a degraded concrete condition. The steel frame supporting each end of the three stacked RWCU heat exchangers rests on concrete pedestals. One of the concrete pedestals had degraded by the loss of concrete from top and side surfaces located adjacent to the bearing surface of the steel frame.
Past repairs were not effective in restoring the concrete due to the thermal expansion of the heat exchangers. The most recent inspection in 2005 confirmed therewas no change in the concrete condition from the previous inspection in 2003 (i.e., 2-year frequency).
The broken concrete condition exceeds the acceptance criteria of hairline cracks and thereforeresponse. This question is resolved.

As a result, an engineering change package has been designed and issued to restore the support structure and is scheduled for implementation. The monitoring frequency will remain at 2-years for this item.
The SMP inspection of the Emergency Diesel Generator Room (Inspection # 05-ED-272-002-03,
- 05-ED-272-004-03) of masonry block walls identified separations between the reinforced concrete wall and the end of the adjoining masonry walls. The vertical joint between the walls has separated from the joint filler such that a small (cracklike) opening has formed at several locations along the joint. The joint filler serves to fill the gap between the two walls and does not contribute to the structural integrity of the walls Therefore, a work order has been issued to repair the filler material. The repair work has not been scheduled.
The monitoring frequency will remain at 2-years for these items.No corrosion was reported during the 2005inspections for reinforced concrete and masonry items.121200Some BWR units have a history of problemswith containment penetration bellows, and the licensees have a long-term replacement program that will continue into the LR period.
The applicant is requested to address this industry operating experience and submit a specific technical basis why the JAFNPP containment penetration bellows are not subject to the aging effects and aging mechanisms observed at these BWRs.The Dresden/Quad Cities License RenewalApplication (LRA) and Safety Evaluation Report (SER) provide a description of the Dresden/Quad Cities operating experience with stainless steel bellows. The Dresden/Quad Cities review determined a total of 120 bellows were within the scope of license renewal. Of these 120 bellows, 24 bellows were identified as being degraded. The root cause was identified as stress corrosion cracking (SCC). From 1990 to 2003 Dresden/Quad Cities replaced or removed the degraded bellows from service. The SER states that several of theThe project team finds the applicant'sresponse acceptable, because the environment conducive to SCC of the stainless steel, containment penetration bellows does not exist at JAFNPP.

No.Audit QuestionsApplicant's ResponseProject Team's Evaluations 74replaced bellows received metallurgical analysis.Analysis results from a couple of examples determined the presence of corrosive products, such as "magnesium salts", chlorides, fluorides, and sulfides. Also, these corrosive species are not typical of containment operating conditions. As a result, the SER concludes the corrosive species, leading to the site specific degradation of the bellows, were most probably introduced during plant construction. (Reference Dresden/Quad Cities SER pages 3-403 to 3-408)Cracking due to SCC for the JAFNPP containmentbellows is not an aging affect requiring management. There is no JAFNPP site-specific operating experience similar to that of Dresden/Quad Cities. In summary, the presence of corrosive contaminants is necessary for SCC to occur. The normal environment for the JAFNPP drywell is dry and there has been no indication of contamination of the bellows during construction. In addition, containment bellows for JAFNPP are not exposed to a corrosive environment. As such, SCC is not applicable to JAFNPP stainless steel bellows. (Ref. LRA paragraph 3.5.2.2.1.7)There is nothing to indicate that the bellows havebeen or would be subjected to corrosive contaminants since the environment is dry and inerted. They are static devices designed for thermal expansion between the drywell and torus during a DBA, therefore they do not experience inservice stresses that would make them susceptible to SCC. The leak rate testing (ref. ST-39B-X201) performed to date provides reasonable assurance that the structural integrity of these expansion bellows remains intact.

The applicant is requested to submit the dates and complete results (at specific locations/not averages or ranges) of all past groundwater monitoring tests. Discuss why the groundwater is non-aggressive, and/or aggressive, if applicable. Confirm that the JAFNPP SMP credited for LR will continue to perform the groundwater monitoring and inspect all inaccessible areas that may be exposed by excavation for any reason, whether the environment is considered aggressive or not, and will also inspect any inaccessible area where observed conditions in accessible areas, which are exposed to the same environment, show that significant concrete degradation occurred.JAFNPP has determined that groundwater is notaggressive and sampling will be done in the future to verify this evaluation. Groundwater at JAFNPP is expected to be non-aggressive similar to Nine Mile which is non-aggressive as stated in the SER for License Renewal of Nine Mile Point Nuclear Station, Units 1 and 2.Values for pH, chloride and sulfate are notavailable. Structures Monitoring Program (SMP) will be enhanced to ensure an engineering evaluation is made on a periodic basis (at least once every five years) of groundwater samples to assess aggressiveness of groundwater to concrete.
For the SMP, JAFNPP will obtain samples from a well that is most representative of the ground water surrounding below-grade site structures. Samples will be monitored for sulfates, pH and chlorides.
Structures Monitoring Program will also inspect any inaccessible concrete areas that may be exposed by excavation for any reason, or any inaccessible area where observed conditions in accessible areas, which are exposed to the same environment, show that significant concrete degradation is occurring. This is license renewal commitment 16.The project team finds the applicant'sresponse acceptable. The applicant has committed (Commitment No.16) to enhance the Structures Monitoring Program to ensure that an engineering evaluation is made on a periodic basis (at least once every five years) of groundwater samples, to confirm that the groundwater remains non-aggressive to concrete during the period of extended operation.

No.Audit QuestionsApplicant's ResponseProject Team's Evaluations 76maintenance rule baseline (initial) inspections wereperformed in 1997 and future monitoring inspection frequencies were established based on the results of the baseline inspections. In cases where random cracks were identified in either reinforced concreteor masonry, a shorter monitoring interval of 2 years was established to confirm the condition was not a degrading condition (i.e., shrinkage cracks). For themajority of cases, the 2-year frequency has been continued until the present. As a result, the multiple inspections of these structures have confirmed the condition is not progressing and will not affect functional capabilities. No additional inspections are required during the next planned inspection for any items that have cracks identified.As discussed in the Item #199 response, the onlycracks of any significance that were reportedduring the 2005 inspection was associated with the RWCU Heat Exchanger concrete pedestal.
However, there were a number of reinforced concrete and masonry items that were inspected in 2005 that contain hairline cracks that were reportedduring previous inspections and continue to be monitored. Any hairline cracks that are identifiedand being monitored in reinforced concrete are reviewed by experienced structural engineers to confirm they are not associated with a structural loading condition. Likewise, most hairline cracks being monitored in masonry construction are located in joint lines and are attributed to shrinkage. Minor pre-existing masonry wall hairline crack in the block face in the Electric Bay (Inspection # 05-TB-272-002-03) and in the West Diesel Fire Pump Room (Inspection # 05-SW-255-006-03) are being monitored on 2-year frequencies.

What was the most significant operating experience related to this program? What were your corrective and preventive actions? When does your next "periodic interval"start?As indicated in LRA section B.1.8, the ContainmentLeak Rate Program is consistent with the NUREG-1801 Section XI.S4, 10 CFR Part 50, Appendix J, Option B program. As documented in the Integrated Leakage Rate Test (ILRT) 5 year extension request (Accession # ML032170128),
the previous 4 ILRTs, dating back to May 1985, showed consistent low leakage and validate the structural integrity of the primary containment.
Consistent with NUREG-1801,Section XI.S4, 10 CFR 50, Appendix J, the Containment Leak Rate Program is a monitoring program without preventive actions. Corrective actions are performed in accordance with 10 CFR Part 50, Appendix J, NEI 94-01, and 10CFR50 Appendix B.Since the 5 year extension request was approved,the next ILRT is to be performed no later than March 7, 2010.

The existing ASME Section XI inspection requirements, including the alternative requirements of ASME Code Case N-481 for pump casings, are adequate for all pump casings and valve bodies. In this way, the ISI program is used to manage the aging effect of "loss of fracture toughness" through analysis instead of monitoring techniques.applicant provides an acceptable basisthat it is applying the NRC recommendations documented in the letter dated May 19, 2000, to manage thermal aging in the CASS pump casings and valves.

The evaluation results were correlated to conditions accepted by the construction radiographs; the radiographs were dispositioned as slag inclusion which was acceptable per ASME Section XI IWB-3112(b).
Because the flaw was acceptable per ASME Section XI IWB-3112(b), no structural safety assessment or calculation was required. Because no calculation is required, there is no TLAA for JAFNPP.The project team finds the applicant'sresponse acceptable because the applicant clarified that it reconciled the flaw indication to a recordable slag inclusion indication that was acceptable for service in accordance with the Section XI flaw evaluation criteria. Since no structural safety assessment or calculation was required, there is no TLAA required for JAFNPP. This question is resolved.

More detail is provided in Section 2.4 of JAF-RPT-05-LRD04.CRD Return Line Nozzle to End Cap WeldIn 2000, JAFNPP discovered a crack on the inside diameter of the weld between the CRD return line nozzle and the end cap. The NRC staff accepted the Fitzpatrick plant Mod JD-00-010 and issued an SER on October 26, 2000. The modification required no calculation involving a time-limited assumption defined by the current operating term.
Weld overlays of this type put the original flaw in compression and qualifying evaluations assume flaw growth to 360 degrees through wall. Future acceptability of the weld is assured through inspections per the guidelines of BWRVIP-75-A.
Therefore, no TLAA was identified.Weld Overlays to Address IGSCC Indications JAFNPP has applied 21 weld overlays to therecirculation system piping and 2 overlays to jet pump instrumentation piping to address flawThe project team finds the applicant'sresponse acceptable. For components repaired with weldoverlays, the applicant provided the project team with the SERs that were issued on these weld overlays. The project team's review of the NRC-issued SERs determined that the NRC did not impose additional fatigue-flaw growth calculations for these weld overlays. For the CRD return line end cap weld overlay, the project team concluded that, since the weld overlay placed the original flaw in compression, flaw growth would be precluded due to the compressive stresses and therefore the analysis did not need to be identified as a TLAA. These weld overlays are inspected as part of the applicant's IGSCC program, which implements the current augmented inspection criteria of BWRVIP-75A program.For flaws detected in the othercomponents addressed in the response, the components were either repaired in accordance with Section XI repair criteria or the flaw growth calculations were used to define the period between inspection Question and Answer Database Audit and Review Related to the License Renewal Application for James A.

The overlays were designed and installed in accordance with Generic Letter 88-01, NUREG-0313, Rev. 2, and ASME Code requirements and approved by the NRC via a SER.
In the qualifying evaluation, the original flaw is assumed to grow to 360 degrees circumferentially and 100% through wall. No credit is taken for the original pipe wall thickness. In addition, the weld metal used is resistant to IGSCC as discussed in BWRVIP-75-A and the specific NRC SER's. Future acceptability of the weld overlay is assured through inspections required by the ISI program and BWRVIP-75-A. There are no TLAA associated with these weld overlays. There are no welds that are monitored for crackgrowth under the ISI Program and / or BWRVIP A. All welds that were determined to contain cracking were repaired by weld overlay.Shroud Cracking JAFNPP performed baseline inspection of theshroud per BWRVIP-76 guidelines during the RO12 and RO13 refueling outages. Calculation JAF-CALC-NBS-04298 determined the inspection intervals to be used for monitoring the noted crack indications. Calculation JAF-CALC-NBS-04298 is not a TLAA since its time-limited assumptions are based on inspection intervals, not the current 40 year operating term. Subsequently, shroud tie-rods were installed to carry the load previously borne by the cracked welds.Steam Dryer Calculations associated with crack indications onthe steam dryer are not TLAA since the associatedintervals and are not defined by thelicensed life of the facility. Therefore these flaw evaluations do not meet the definition of a TLAA in 10 CFR 54.3. This question is resolved.

These crack indications are monitored by the BWR vessel internals program per BWRVIP-18A guidelines.Main Steam Nozzle UT inspection performed as part of the JAFNPP ISIprogram revealed a subsurface indication on main steam nozzle N3C. There has been no discernable change in the size of the indication during subsequent inspections. This indication is believed to be a flaw remaining from vessel construction and will continue to be monitored by ISI. There is no associated calculation with a time-limited assumption and, therefore, no TLAA is associated with this indication.Torus Crack In June of 2005 a small through-wall crack wasidentified in the torus shell in the vicinity of the torus support between bays "A" and "P". Failure analysis indicated that the crack was likely caused by fatigue due to condensation oscillation associated with operation of the HPCI exhaust discharge to the torus. This crack was repaired. In followup inspections, two additional cracks werefound. These two cracks were also repaired.

The cause of this crack was determined to be low stress, high cycle fatigue at the heat affected zone of the weld resulting from increased pipe movement during operation due to inadequate pipe engagement of an adjacent support (PFSK-2084) during original installation. This pipe and the associated support were repaired in accordance with code requirements.. An additional inspection in 2006 discovered two additional cracks which were alsorepaired. No analysis involving a time-limited assumption defined by the current operating term is associated with the repair, and therefore, there is no TLAA associated with this piping crack.No JAFNPP flaw growth analyses were identifiedthat would qualify as TLAA (i.e., no other analyses were performed to qualify acceptability of flaws for the current operating term of the plant).146244Identify all BWRVIP Reports includingcomponents that are within the scope of AMP B.1.7, "BWR Vessel Internals."

Clarify and discuss what types of alternativeinspection method, inspect frequency, and inspection sample size will be used to inspect the core plate rim hold down bolts in lieu of the recommended BWRVIP-25 examinations;c). Clarify, using a technical discussion andjustification, how the examination method, inspection frequency, and inspection sample size for the alternative program will be capable of managing cracking in the core support plate rim hold-down bolts for the PEO.JAFNPP developed technical justifications fordeviation from the guidelines of BWRVIP-25 in accordance with the guidance given in Appendix A to BWRVIP-94. This appendix does not provide technical justification in and of itself, rather it provides administrative guidelines for processing a technical justification; Entergy is deviating from the guidelines of BWRVIP-25 because the method proposed for core plate rim hold down bolts is not feasible. JAFNPP plans to perform the inspections required by ASME Section XI as an alternate method for inspection of the Core plate rim hold down bolts.The examination method, inspection frequency,and inspection sample size for the alternative inspection method will be in accordance with the requirements of ASME Section XI, Table IWB-2500-1, Examination Category B-N-2.LRA Section A.2.1.7 and Section B.1.7 will berevised to include the following enhancement.JAFNPP will perform inspections of the core platerim hold down bolts in accordance with ASME Section Xl Table IWB-2500-1, Examination Category B-N-2 or in accordance with a future NRCapproved revision of BWRVIP-25 that provides a feasible method of inspection.This requires a LRA amendment.
License Renewal Commitment Number 21specifies implementation of enhancements to theIn LRA Amendment No. 9, dated April 6,2007, the applicant provided LRA Commitment No. 23 to address aging management of the core plate rim hold-down bolts and structural integrity of the core plate for the period of extended operation. The basis for using this commitment as the basis for ensuring the structural integrity of the core plate for the period of extended operation is discussed in SER section 3.0.3.2.7. This commitment supersedes the applicant's response to the project team's question.
This question is resolved.

No.Audit QuestionsApplicant's ResponseProject Team's Evaluations 98BWR Reactor Vessel Internals Program describedin LRA Section A.2.1.7 and Section B.1.7.155255Exception 2 states that "A focused inspection ofthe bottom surface of the shroud support H9 weld" will be performed. The footnote for this inspection states that the examination will be done in accordance with BWRVIP guidelines.
Confirm whether or not Entergy is referring to the inspection criteria for shroud support structures in Topical Report BWRVIP-38.Yes, JAFNPP will inspect the H9 weld asrecommended in BWRVIP-38 (flow chart on page
3-17).The project team finds the applicant'sresponse acceptable because the applicant confirmed that it is applying the inspection criteria of Topical Report BWRVIP-38 for inspection of the H9 weld in the core shroud. The NRC endorsed BWRVIP-38 for implementation in a SE dated March 1, 2001. This question is resolved. 156256Exception 3 states, in part, that the inspectionof the top guide hold down assemblies at the 0 and 180 azimuthal locations were deferred from refueling outage 16 (RO16) to refueling outage 17 (RO17) with technical justification. State what the BWRVIP-26 criteria are for inspecting these components and provide the details of the technical basis that was used to defer the examinations of the components to RO17 and a justification why this basis formed an acceptable reason to defer the examinations to
RO17.Deferral of the top guide hold down assemblies atthe 0° and 180° from R16 to R17. At JAF, hold-down assemblies are inspected with a conservative decision making philosophy. In that, JAF has been inspecting the hold down assemblies despite BWRVIP-26-A, Figure A-1 showing that the FitzPatrick plant faulted vertical loads at hold down assemblies are on the demarcation line between "lift off" and "will not lift". Therefore, the hold down assemblies will not lift-off during a postulated seismic event. The deferred inspections from R16 were completed in R17 (2006). No indications were noted.The project team finds the applicant'sresponse acceptable because the applicant has been inspecting the top guide hold down assemblies in accordance with BWRVIP-26A even though the BWRVIP's evaluation of lift forces for BWR top guides indicates that the top guide at FitzPatrick will not lift under a postulated faulted event. Thus, a one-cycle deferral of the examination is justified and the inspections during RO17 did not detect any indications of cracking in the top guide rim hold down assemblies.
This question is resolved. 157257The BWR Internals Program includes thefollowing footnote (Footnote 2) on the "Detection of Aging Effects" program attribute for the AMP, as it pertains to performing the augmented inspections of jet pump assembly components under BWRVIP-41.Welds at TS-1, TS-3 and TS-4 are inaccessiblefor inspection. There is no inspection techniqueDetails of the technical justification (DeviationDisposition) are found in ER# [[::JAF-05-34054|JAF-05-34054]], dated 3/17/06, which was available for review on site.
However, JAFNPP inspected the jet pump beams and the high priority welds that were the subject of the technical justification by UT in R17 (October 2006). BWRVIP-41 requires inspection of the inaccessible jet pump welds only upon development of a feasible inspection method.The project team finds the applicant'sresponse acceptable because the basis for the deviation was documented in a Deviation Disposition, as reported in ERNo. [[::JAF-05-34054|JAF-05-34054]], dated March 17, 2006, and because the applicant inspected the jet pump beams and high priority jet pump welds by UT in October of 2006. The augmented inspection Question and Answer Database Audit and Review Related to the License Renewal Application for James A. Fitzpatrick Nuclear Power plant No.Applicant'sRef. No.Audit QuestionsApplicant's ResponseProject Team's Evaluations 99developed to inspect the thermal sleeve welds.However, the BWRVIP/ EPRI NDE Center has new plans to develop an inspection capability.
The BWRVIP is also pursuing analyses which may reduce or alleviate inspection of the TS-1 through TS-4 welds. Inspection is recommended when techniques or accessibility becomes available. Also, there are other welds mainly along the diffuser lower section where coverage is low due to interference from core shroud gussets, tierods, and others. The BWRVIP is also pursuing an analysis to reduce or alleviate inspection of the adapter welds. A technical justification for inspecting inaccessible jet pump welds, and the deferral of beam UT inspection has been prepared per BWRVIP-94 guidelines. Finally, several high priority ranked welds in JP-1,2,3, 4, 19 and 20 previously scheduled for inspection in RO16, were deferred to RO17 (one cycle deferral) with technical justification.The technical justification in this exception forjustifying deferral of the augmented inspections for the jet pump assembly components covered in Footnote 2 does not credit any inspection-based aging management criteria for these components. Provide your basis for concluding that the deferral of the augmented examinations for those jet pump assembly components addressed in Footnote 2 is valid and that other augmented inspections of other jet pump assembly components performed to date and in the future in accordance with BWRVIP-41 will be sufficient to ensure the integrity of the jet pump assemblies during the period of extended operation for JAFNPP.Therefore, the exception addressed by Footnote 2is no longer applicable. Appendix B of the LRA will be revised to delete the exception for the jet pump assembly.
Because they are based on industry-wide BWR operating experience, the inspection activities of BWRVIP-41 are considered sufficient to ensure the integrity of the jet pump assemblies during the period of extended operation for JAFNPP.This requires an LRA amendment.recommendations in BWRVIP-41 call forinspections of inaccessible welds only if a feasible inspection method is developed.
Therefore, the project team concurs that the exception identified in Footnote (2) of the BWR Vessel Internals Program is no longer applicable or necessary.The staff has endorsed the inspection andflaw evaluation guidelines in BWRVIP-41 for jet pump assembly components in a safety evaluation dated June 5, 2001 (ADAMS Accession No. ML011570460).The Applicant amended the LRA to clarifythe above as stated in amendment letter No. 5, dated February 01, 2007.

The LRA does not mention the water storage tanks. Does JAFNPP have water storage tanks associated with its Fire Water System? If so, what is the justification for not including in AMP B.1.13.2 and how are the aging effects managed?JAF does not utilize a water storage tank for fireprotection water. The fire water source is Lake Ontario. Further details regarding the fire water system are provided in JAF-RPT-05-AMM14, Aging Management Review of Fire Protection - Water System, which was available for review on site.The project team finds the applicant'sresponse acceptable because JAF does not utilize a water storage tank for fire protection water and hence they are not included in the program. This question is resolved.159259The exception for AMP B.1.13.2, "ParametersMonitored/Inspected" program element states that the periodic flow testing of the water system is performed in accordance with Section 11, Chapter 5 of the Fire Protection handbook. NUREG -1801, Revision 1, states that the periodic flow testing of the water system should be performed using the guidelines of NFPA 25. Describe the differences between these documents. Provide the technical basis why flow testing of the water system performed in accordance with Section 11, Chapter 5 of the Fire Protection handbook is acceptable.The method of performing the flow testing is inaccordance with Chapter 5, Section 11 of the Fire Protection Handbook, 14th Edition. This is the same as the flow test required by NFPA 25.The project team finds the applicant'sresponse acceptable because a comparison of Section 11, Chapter 5 of the Fire Protection Handbook and NFPA 25 confirmed that the extent of the testing requirements, the acceptance criteria and the analysis of the test data outlined in Section 11, Chapter 5 of the NFPA Fire Protection Handbook followed the guidance provided in NFPA 25. Overall, staff noted that the NFPA Fire Protection Handbook periodic water flow testing follows the NFPA 25 recommendations and is adequate to assess the ability of the system to perform its intended function. This question is resolved.160260The exception for AMP B.1.13.2, "Detection ofAging Effects" program element states that visual inspection, re-racking and replacement of gaskets in couplings occurs at least once per operating cycle. NUREG -1801, Revision 1, specifies an annual inspection frequency.
Provide a technical basis why the proposed frequency is acceptable.Per NUREG-1800, Table 2.1-3, gaskets areconsumables not subject to aging management review. Therefore, the exception to the Fire Water System program related to annual gasket inspections incorrectly states an exception to the inspection frequency. The exception should state that gaskets are not subject to aging management review since they are periodically inspected, testedThe project team finds the applicant'sresponse acceptable because visual inspection, re-racking and replacement of gaskets is done in accordance with Plant Technical Requirements Manual and is the current licensing basis.

If the foregoing statement is true, what are the fire water systems that are NOT normally maintained at required operating pressures and why?Deluge, dry pipe and preaction sprinkler systemsare not maintained at normal system operating pressure. The systems are normally dry and will only fill with water when a fire is detected. The fire hose standpipe located in the MG set fan room is normally maintained dry due to the potential for freezing. If needed, the standpipe is filled and pressurized by use of a local valve.The project team finds the applicant'sresponse acceptable because deluge, dry pipe and pre-action sprinkler systems are not normally maintained at required operating pressures. These systems are normally dry and will only fill with water when a fire is detected. This question is resolved.162262The fire hoses were excluded from agingmanagement as an exception to NUREG 1801, Rev 1, as a category (c) consumable per the guidelines of NUREG 1800. Why wasn't it excluded as a category (d) consumable instead?LRA Section B.1.13.2 states "the hoses are notsubject to aging management since they are periodically inspected, hydrotested, and replaced."
This matches the category (d) criterion of "typically replaced based on performance or condition monitoring." Inspection, testing, and replacement of fire hoses are conducted per JAFNPP Technical Requirements Manual, Rev. 12, at least once every 18 months (24 months in high radiation areas) andThe project team finds the applicant'sresponse acceptable because inspection, testing, and replacement of fire hoses are conducted per JAFNPP Technical Requirements Manual, Rev. 12.

This question is resolved. 163263The enhancement for wall thickness evaluationof fire protection piping is identified in the Appendix A write-up in the present tense, meaning the inspections are being performed.
However the enhancement is addressed in Appendix B (Detection of aging effects) in the future tense, meaning the inspections will be performed in the future (before the end of the current operating term). The Appendix A should be revised to address this future commitment.Appendix A was written from the perspective ofentry into the period of extended operation. At that time, all aging management programs will be in place. From that perspective, it is appropriate for the UFSAR supplement to be written in present tense. A list of commitments is provided during the license renewal review that clearly shows the commitments for program enhancements.The project team finds the applicant'sresponse acceptable because it is appropriate for the UFSAR supplement to be written in present tense to reflect the condition during the PEO . This question is resolved.164264The enhancement for revising procedures toinclude inspections of hose reels for corrosion is not addressed in Appendix A. Appendix A should be revised to address this future commitment.Section A.2.1 of the LRA states, "All agingmanagement programs will be implemented prior to entering the period of extended operation."

Currently there is no discussion of aging management review performed for the foam system in the LRA.
Please discuss the aging management review for the foam system. The staff requests the applicant to provide a technical justification of why an AMP is not required or provide an AMP that contains the required ten elements.Aging management review of foam systems isprovided in Table 3.3.2-5 (environment - fire protection foam) with discussion in Section 2.3.3.5.
The aging effects from fire protection foam are less than the aging effects of raw water and are managed by the Fire Water System Program.The project team finds the applicant'sresponse acceptable because the AMR of foam systems is provided in Table 3.3.2-5 (environment - fire protection foam) with discussion in Section 2.3.3.5. This question is resolved.166266The basis provided for exceptions to"Parameters Monitored or Inspected" program element is not valid since the Flash Point of an industrial lubricant is an important test to determine if light-end hydrocarbons are getting into the oil through seal leaks or other means. It is an effective way to monitor seal performance in light end hydrocarbon compressors. Low Flash Points pose a safety hazard in the event of component failure that can generate heat above the flash point of the oil, such as bearingThe flash point test is performed at JAF for theemergency diesel engine oils in addition to filter residue or particle count, viscosity, total acid/base (neutralization number), water content, and metals content. The flash point test is one method for the detection of oil that has been contaminated with light-end hydrocarbons such as fuel oil. While it is important from an industrial safety perspective to monitor flash point, it has little significance with respect to the effects of aging. As such it is only utilized in scope components such as dieselThe project team finds the applicant'sresponse acceptable because a flash point reading of the West Diesel Fire Pump engine lubricant is taken annually with an engine oil change of every six years. Since the lubricating oil in the engines of the security backup generator and the emergency diesel generator are changed on a regular basis these components do not require the flash point tests specified in this section of the GALL Question and Answer Database Audit and Review Related to the License Renewal Application for James A.

The West Diesel Fire Pump has a scheduled 6 year oil change frequency, but will be changed more often if the 6 month sample deems necessary. The Security Generator oil is changed annually and therefore, does not require a flash point test. Therefore, the exception listed in the LRA B.1.20 is not required and will be removed.

The applicant committed to amend the LRA to remove this exception. In its response dated February 1, 2007, the applicant revised the LRA Section B.1.20 to delete this exception. This question is resolved.167268LRA Section 2.3.3.6 describes the carbondioxide (CO
- 2) fire suppression system as beingin scope of the license renewal and subject to an AMR. The AMP for CO 2 fire suppressionsystem does not appear in LRA Section B.1.13.1, "Fire Protection Program."The NUREG-1801, GALL Report SectionXI.M26, "Fire Protection," describes the requirements for aging management of the CO 2fire suppression system. It requires that an AMP be established to evaluate the periodic visual inspection and function test is performed at least once every six months to examine the signs of degradation of CO 2 fire suppressionsystem. Material conditions that may affect the performance of the system, such as corrosion, mechanical damage, or damage to dampers, are observed during these tests. The staff requests that the applicant describe AMP and operating experience for the CO 2 firesuppression system in LRA Section B.1.13.1As noted in Table 3.3.2-6 of the application, theaging effects of the fire protection - CO 2 systemcomponents are managed by the Bolting Integrity Program (Section B.1.30) and by the Fire Protection Program (B.1.13.1). The Fire Protection Program is consistent with NUREG-1801 Section XI.M26 which as noted in the question includes activities to manage the effects of aging on the intended functions of the fire protection - CO 2system. A review of station operating experience identified no aging-related degradation adversely affecting the operation of the CO 2 system.CO 2 fire suppression valve position check andoperational tests are performed quarterly (once per 92 days). In addition, CO 2 storage tank level andpressure are checked monthly in accordance with surveillance test ST-76A. Full CO 2 systemfunctional tests are performed once per 24 months in accordance with the station's current licensing basis. An inspection of external surfaces of the
CO 2 fire suppression system is performed at leastonce every six months to check for signs of degradation.The project team finds the applicant'sresponse acceptable because it will include C O2 within the scope of theprogram. Specifically, in its response dated February 1, 2007, the applicant amended the LRA (Amendment No. 5)
"program description" Section B.1.13.1 to state "The program also includes Plant
C O2 fire suppression system valve positionchecks and operational tests, C O2 storagetank level and pressure checks, systemfunctional che cks, and external surfaceinspections," In addition, the applicant added anexception to LRA Section B.1.13.1 to perform the full C O2 system functional test on a 24-month basis rather than the six-month periodicity listed in NUREG-1801 element "detection of aging effects." The current licensing basis (CLB) for JAFNPP is to perform the full C O2 system functionaltest on a 24-month basis in accordance with JAFNPP TRM Section 3.7.J. The Question and Answer Database Audit and Review Related to the License Renewal Application for James A. Fitzpatrick Nuclear Power plant No.Applicant'sRef. No.Audit QuestionsApplicant's ResponseProject Team's Evaluations 105A reference to the plant CO 2 fire suppressionsystems will be added in the program description of LRA Section B.1.13.1 (Fire Protection Program). In addition, an exception to the six-month periodicity listed in NUREG-1801 for the full CO 2 systemfunctional test will be added to LRA Section B.1.13.1 to perform this functional test on a 24-month basis as listed in the current licensing basis for JAF. This frequency is considered sufficient to ensure system availability and operability based on station operating history and to ensure that aging related effects will be properly managed through the period of extended operation. The NRC Staff, as documented in the SER for Oyster Creek, has accepted the position that, in the absence of aging-related events adversely affecting system operation and provided that visual inspections of component external surfaces are performed every six months, the periodicity specified in the current licensing basis for functional testing of the CO 2 system issufficient to ensure system availability and operability. These items each require an LRA amendment.code of record for the C O2 fire suppressionsystem is NFPA 12, 1968 Edition. This edition did not specify any frequency for the C O2 fire suppression system functionaltest. The surveillance frequency for the
C O2 fire suppression system to performfunctional test provided in the GALL Report is based on the current NFPA 12.The 24-month C O2 fire suppressionfunctional test frequency is part of the CLB and the review of JAFNPP operating experience indicated that this frequency is reasonable to manage the aging effects.
The 24-month frequency is considered sufficient to ensure system availability and operability based on the plant operating history, and that there has been no aging-related event that has adversely affected system operation. Because these aging effects occur over a considerable period of time, the project team concluded that the 24-month inspection interval will be sufficient to detect aging of C O2 firesuppression system.

This question is resolved.171278Generic Question on AMRs - Sections 3.1 to3.4 (1)1. The staff noted that certain Table 1 AMRline-items correctly credit the OTI program to verify the effectiveness of the Water Chemistry-BWR AMP, when necessary. However, the Table 2 AMR line-items corresponding to these Table 1 line-items do not credit the OTIThe One-Time Inspection Program is credited inthe Table 2 AMR entries when it is used to verify the effectiveness of other AMPs in the LRA. A plant-specific note is included for the each Table 2 line item crediting a water chemistry control program. This note indicates that the One-Time Inspection Program will verify the water chemistry control program's effectiveness. Since the One-Time Inspection Program is a sampling program,The project team finds the applicant'sresponse acceptable because the effectiveness of the water chemistry control program associated with each AMR line item is confirmed by the One-Time Inspection Program, irrespective of whether the One-Time Inspection Program is one of the AMPs, a note indicating its inclusion as one of the AMPs, or water Question and Answer Database Audit and Review Related to the License Renewal Application for James A. Fitzpatrick Nuclear Power plant No.Applicant'sRef. No.Audit QuestionsApplicant's ResponseProject Team's Evaluations 107program. Instead, a plant-specific note isincluded for the Table 2 line-items indicating that the OTI program will verify the effectiveness of the Water Chemistry-BWR program. This is inconsistent with the guidance provided in NUREG-1801, Revision 1 and NEI 95-10, Revision 6.The staff has three concerns with the approachused in the JAFNPP LRA for crediting the OTI program as a verification program.i. The plant-specific note used for the Table 2AMR line-items does not provide a clear commitment as to how the OTI program will be implemented to verify the effectiveness of the AMP credited for that AMR. The staff finds this plant-specific note is vague and, therefore, unacceptable.ii. Crediting the OTI via a plant-specific noteminimizes the importance placed on this verification inspection. When OTI is credited to verify the effectiveness of an AMP, the staff considers this a critical element for accepting the AMR. Including the OTI in a note does not reflect the importance level placed on this verification by the staff.iii. The staff is concerned that the OTI could beoverlooked if it is not included directly in each of the Table 2 AMR line-items for which it is credited. Please explain why the OTI program is not credited in the Table 2 AMR entries when it is used to verify the effectiveness of other AMPs in the LRA. In the response, please address each of the aforementioned staff concerns with this approach. This applies to Sections 3.1 through 3.4 of the LRA.every individual component is not subject to aninspection. Consequently, the One-Time Inspection Program is more appropriately associated with the applicable water chemistry program. The plant-specific note is intended to simplify the tables in Sections 3.1 through 3.4 of the LRA. Since the plant specific note is applied to every line item crediting a water chemistry control program, it should be understood by the reader that effectiveness of the water chemistry program associated with each line item is confirmed by the One- Time Inspection Program.This is not inconsistent with NUREG-1801,Revision 1, which does not prescribe how the tables in Sections 3.1 through 3.4 of the LRA should look, but merely states that water chemistry control AMPS are "to be augmented by verifying the effectiveness of water chemistry control. See Chapter XI.M32, "One-Time Inspection," for an acceptable verification program." The LRA clearly indicates that this is the case as described above.It is also not inconsistent with NEI 95-10, Revision6 which also does not prescribe how the tables in Sections 3.1 through 3.4 of the LRA should look, but merely states that Sections 3.1 through 3.4 of the LRA "contain tables that summarize the aging management reviews for the systems. This subsection also contains a summary of the materials, environments, aging effects requiring management and aging management programs for each subsystem." NEI 95-10, Revision 6 also does not indicate how plant-specific notes should be used, but states only that, "Any notes the plant requires that are in addition to the standard notes will be identified by a number and deemed plant-specific."chemistry control program alone. It shouldbe understood that including the One-Time Inspection Program in a note rather than in the Aging Management Program column of the tables does not minimize its importance. To implement this AMP, the entire list of components crediting water chemistry control programs for aging management will have to be considered to determine the representative sample for inspection. Therefore, the One-Time Inspection Program cannot be overlooked even though it is not listed in the Aging Management Program column of the Table 2 AMR line-items. This question is resolved.
Question and Answer Database Audit and Review Related to the License Renewal Application for James A. Fitzpatrick Nuclear Power plant No.Applicant'sRef. No.Audit QuestionsApplicant's ResponseProject Team's Evaluations 108Each of the staff's concerns with this approach isaddressed below.I. That is correct, the plant-specific note used forthe Table 2 AMR line-items does not provide a clear commitment as to how the One-Time Inspection program will be implemented to verify effectiveness of the water chemistry control programs. However, listing the One-Time Inspection Program in the Aging Management Program column of the table for each line item crediting a water chemistry control program also does not provide a clear commitment as to how the One-Time Inspection Program will be implemented.
The commitment to implement the One-Time Inspection Program is contained in LRA Section B.1.21 and in LRA Appendix A.II. As stated above, the plant-specific note is notintended to obfuscate use of the One-Time Inspection Program. It is intended to simplify the tables in Sections 3.1 through 3.4 of the LRA.
Since the plant specific note is applied to every line item crediting a water chemistry control program, it should be understood by the reader that effectiveness of the water chemistry control program associated with each line item is confirmed by the One-Time Inspection Program.
Including the One-Time Inspection Program in a note rather than in the Aging Management Program column of the tables does not minimize its importance. See response to iii, below.III. The commitment to implement the One-TimeInspection Program is contained in LRA Section B.1.21 and in Appendix A. In accordance with NUREG-1801, XI.M32, with which the One-Time Inspection Program is consistent, the inspection includes a representative sample of the population, Question and Answer Database Audit and Review Related to the License Renewal Application for James A. Fitzpatrick Nuclear Power plant No.Applicant'sRef. No.Audit QuestionsApplicant's ResponseProject Team's Evaluations 109and, where practical, focuses on the bounding orlead components most susceptible to aging due to time in service, severity of operating conditions, and lowest design margin. Engineering report JAF-RPT-05-LRD-02, Aging Management Program Evaluation Report, (AMPER) is available for onsite review. The description of this one-time inspection activity in Attachment 2 of the AMPER states that, "A representative sample of components crediting water chemistry control programs for aging management will be inspected. However, due to a history of low oxygen and high iron (magnetite) content in the Reactor Building Closed Loop Cooling System, a specific sample of components in this system will be inspected." To implement this activity, the entire list of components crediting water chemistry control programs for aging management will have to be considered to determine the representative sample. Therefore, the One-Time Inspection Program cannot be overlooked even though it is not listed in the Aging Management Program column of the Table 2 AMR line-items.1722792. In reviewing the AMR line-items presented inSections 3.2, 3.3, and 3.4 of the JAFNPP LRA, the staff noted that the Diesel Fuel Monitoring Program (AMP B.1.9) and the Oil Analysis Program (AMP B.1.20) are correctly credited to manage loss of material for components exposed to fuel oil and lubricating oil, respectively. NUREG-1801, Revision 1, recommends that the effectiveness of these programs be verified, and a one-time inspection (OTI) of selected components at susceptible locations is noted to be an acceptable method of verification. The further evaluations in the LRA state that during the past five years, many visual inspections of components have beenOil Analysis One-time Inspection Activities toconfirm the effectiveness of the Oil Analysis Program will be added to the One-Time Inspection Program and applicable sections of the LRA revised. This requires an amendment to the LRA.Diesel Fuel Monitoring One-time Inspection The inspections that are being credited in lieu of aone-time inspection include visual inspections of components at the most susceptible locations for components containing fuel oil such as the bottom of tanks. The aging effects of loss of material and cracking can only occur in the presence of water. If significant water accumulation is not allowed toFor in-scope components that are subjectto AMR and are exposed to diesel fuel oil, the applicant's periodic visual testing in accordance with its Diesel Fuel Oil Monitoring Program. This is consistent with the [Detection of Aging Effects]
program element in GALL AMP XI.M30, "Fuel Oil Chemistry," and is acceptable.
Thus, a one-time time inspection of the diesel fuel oil tanks is not necessary because the visual examinations of the diesel fuel oil tank is performed on a periodic basis when the tank is drained for cleaning. As has been indicated in the applicant's response, the applicant also Question and Answer Database Audit and Review Related to the License Renewal Application for James A. Fitzpatrick Nuclear Power plant No.Applicant'sRef. No.Audit QuestionsApplicant's ResponseProject Team's Evaluations 110performed during corrective and preventivemaintenance activities. These past inspections at JAFNPP serve in lieu of a one-time inspection to provide confirmation of the effectiveness of the Diesel Fuel Monitoring Program and the Oil Analysis Program. The staff has the following concerns with crediting past inspections performed as part of corrective and preventive maintenance activities to serve in lieu of a one-time inspection.I. A one-time inspection includes severalelements regarding the sample size, inspection locations, examination techniques, and follow-up inspections that may not be met by inspections performed during corrective and preventive maintenance. The staff considers each of these elements to be important in verifying the effectiveness of an AMP. Unless all elements are addressed, the staff would consider the approach unacceptable.ii. Both AMPs ( B.1.9 and 1.20) described in theLRA include enhancements that will be implemented prior to the period of extended operation. As such, inspections performed during the past five years may not be representative of the AMP's effectiveness for the period of extended operation, which will include implementation of the enhancements.Please provide the technical justification forcrediting inspections performed during the past five years as part of corrective and preventive maintenance to serve in lieu of a one-time inspection for the purpose of verifying the effectiveness of AMPs B.1.9 and B.1.20. In your response, please address each of the staff's concerns with this approach. Thisoccur, then these aging effects cannot occur. Theuse of visual inspections is an effective and appropriate method for detecting loss of material, fouling and cracking which would be indicative of an ineffective aging management program.The sample population includes the mostsusceptible locations for water accumulation, which are the low points in systems such as the bottom of tanks or drain lines where aging effects such as loss of material or cracking would most likely occur.
If aging effects are not detected at these locations then it is highly unlikely that they would be occurring in other portions of the systems. This provides objective evidence of the effectiveness of the aging management programs. Unacceptable inspections will be evaluated under the site corrective action program and the inspection population will be expanded.The Diesel Fuel Monitoring Program applies to allthe systems that contain fuel oil including the emergency diesel generators (EDG), and the fire protection diesel. The aging effect managed by the Diesel Fuel Monitoring Program is loss of material.
Three of the four EDG fuel oil storage tanks have been inspected since 2001 with the most recent in 2004. These inspections occur every 10 years and revealed no abnormal conditions such as corrosion. In addition, components on the EDG's that contain fuel oil are routinely inspected during engine overhauls. These inspections have also not revealed any instances of significant loss of material. These inspections are periodic activities that occur on an ongoing basis rather than just one time. The performance of these inspections within the past five years is sufficient since the operating license for JAFNPP expires in 2014 and the inspections being credited have been performedperforms additional inspection of dieselgenerator components that go beyond the recommendations of GALL. This is acceptable.

This provides almost 30 years ofoperation and exposure to the environments such that latent aging effects would be apparent. In addition, this is consistent with GALL XI.M34 which credits inspections performed during the 10 years prior to the period of extended operation. The enhancements for the Diesel Fuel Monitoring Program will improve the programs such that aging effects are more effectively managed. Past inspection results have found that the existing programs are effective in managing aging effects.
The enhancements to the program will only improve the effectiveness of the program and have no adverse impact on the program such.Current periodic inspections are credited in lieu ofone-time inspection associated with the Diesel Fuel Monitoring Program and are consistent with the One-Time Inspection Program as described in GALL Section XI.M32.1732803. LRA Tables 3.3.2.14- 1, 2, 3,4,7, 8, 10, 14,16, 17, 19, 20, 21, 22, 42, and 44 address nonsafety- related components affecting safety-related systems. However, these Tables address all such systems in section 3.3, Auxiliary Systems, even though some of these systems belong to Section 3.2, ESF systems and Section 3.4, Steam Power Conversion Systems. This LRA format is inconsistent with NUREG 1800, Revision 1 and NEI 95-10, Revision 6. The staff's SER is written based on systems as defined in SRP and GALL Report Sections 3.2, 3.3, and 3.4. As written in the LRA, it will make the SER documentation difficult and confusing because the SER Sections 3.2 and 3.4 will include Tables from Section 3.3.
Please justify why the non-safety systemsSection 14 includes all the systems that haveintended functions that meet 10 CFR 54.4(a)(2) for physical interaction. To indicate individual systems included in the aging management review for (a)(2), Table 3.3.2-14 is subdivided by system. For example, Table 3.3.2-14-22 is for the circulating water system, a system which only has components included for (a)(2). For the core spray system, Table 3.3.2-14-8 shows the components included for (a)(2) but since the system is also in scope for other reasons, Table 3.2.2-2 shows the components included for 54.4(a)(1) and (a)(3).
The aging management review of the systems thathave functions that met 10 CFR 54.4(a)(2) for physical interaction was done separately from the review of systems with intended functions that metThe project team reviewed the applicant'sresponse and determined that this approach to presenting the AMRs for systems that have intended functions that meet 10 CFR 54.4(a)(2) for physical interaction impedes the review process rather than facilitating it since the SER preparation is based on systems as defined in SRP-LR, which includes six specific sections. Each reviewer focuses on a specific section, and all of the systems included in that section.
Therefore, the approach used in this LRA makes the review more cumbersome since the reviewers must also review Section 3 on auxiliary systems to ensure that all systems in their scope are addressed. However, the project team Question and Answer Database Audit and Review Related to the License Renewal Application for James A. Fitzpatrick Nuclear Power plant No.Applicant'sRef. No.Audit QuestionsApplicant's ResponseProject Team's Evaluations 112associated with ESF and Steam PowerConversion Systems were included in the Auxiliary System.10 CFR 54.4 (a)(1) or (a)(3). The results of thisreview were presented separately so that they could be reviewed separately on the basis of physical proximity rather than system function. This allows a reviewer to clearly distinguish which component types in a system were included for 10 CFR 54.4(a)(2) for physical interaction. Since most of these systems are auxiliary systems they were added as part of the auxiliary systems section.determined that this approach isadministrative in nature, and does not impact the technical accuracy of these AMRs. Therefore, the project team finds it acceptable for this LRA. This question is resolved. 174281The aging management program column of theAMR line item states that the inservice inspection program and water chemistry program will be credited with aging management of SCC, IGSCC, and IASCC in the access hole covers. In contrast the discussion column of the AMR line item states that the BWR Internal Program and the Water Chemistry Program will be used for aging management of SCC, IGSCC, and IASCC.
Resolve the difference between the column entries and clarify which inspection-based AMP, along with the Water Chemistry Program, will be used to manage these cracking mechanisms in the access hole covers.The aging management program column entries inTable 3.1.1 (in fact entries for all but the discussion column) are quoted from GALL. In line 3.1.1-49, GALL recommends the ISI program and water chemistry while the Discussion column entry indicates JAFNPP has chosen to credit the BWR internals program along with water chemistry.
This difference of programs is reflected in the use of note E in the next to last entry on page 3.1-55 of the application. The comparison of the manway covers (access covers) portion of this line is to GALL item IV.B1-5 using the BWR Vessel Internals and water chemistry programs, consistent with other parts of the shroud support that are compared to IV.B1-2.The project team finds the applicant'sresponse acceptable because the applicant is using the BWR Vessel Internals Program and the augmented inspection criteria of BWRVIP-38 for the inspections of shroud support components, including the shroud manway covers (i.e, access hole covers).
BWRVIP-38 was endorsed by the NRC for use in a safety evaluation dated March 1, 2001. The BWRVIP-38, as endorsed by the staff provides a basis for the inspections of the manway covers. Refer to Item 135 for additional bases for acceptance. This question is resolved. 175282The discussion section in GALL AMR line itemIV.B1-5 (R-94) states that "because cracking initiated in crevice regions is not amenable to visual inspection, for BWRs with a crevice in the access hole covers, an augmented inspection is to include ultrasonic testing (UT) or other demonstrated acceptable inspection of the access hole cover welds." In the discussion of AMR-line item 3.1.1- 49, Entergy states that "JAFNPP has welded access hole covers withJAFNPP does not have a piping andinstrumentation diagram that shows the core support plate access hole covers. They are shown (by sketch) in BWRVIP-15, Section 10. Excerpts from Section 10 are attached below. Note in the blow-up portion of Figure 2.10.2.4 that the access hole cover is welded to the shroud support ledge with a full penetration weld that leaves no crevice behind the weld. The JAFNPP plant specific configuration is shown on drawing 5.02-16.The project team finds the applicant'sresponse acceptable because the plant-specific configuration in JAFNPP drawing 5.02-16 provides sufficient evidence that the weld configuration for the manway cover (access hole cover) does not create a creviced region. Based on this evidence, the project team concludes that the augmented UT examination recommended in GALL AMR IV.B1-5 (R-Question and Answer Database Audit and Review Related to the License Renewal Application for James A. Fitzpatrick Nuclear Power plant No.Applicant'sRef. No.Audit QuestionsApplicant's ResponseProject Team's Evaluations 113no crevice behind the weld." It is not clear howthe access hole cover could be welded to the support plate without creating a creviced region in the access hole cover design. Demonstrate, using an appropriate piping and instrumentation diagram (P&ID), how and why the welded access hole cover configuration does not create a creviced region in the core support plate design. If upon further review it is determined that the welded configuration does create a creviced region in the support plate design, the staff requests that the inspection-based program for the access hole covers (i.e.
presumably the BWR internals program) be augmented to include a UT examination of the access hole cover weld, as is recommended by the NRC position established in GALL AMR line item IV.B1-5.94) does not need to be performed for theperiod of extended operation, and the augmented inspections recommended in BWRVIP-38 are adequate to use as the basis for inspecting the manway cover.
This question is resolved. 176283LRA Section 3.5.2.2.1.4 ( Loss of material dueto General, Pitting and Crevice Corrosion) -
Please explain the last statement in this section "Therefore, significant corrosion of the drywell shell is not expected." What does this mean?
Does this mean that JAFNPP has identified some corrosion, but not significant? Define what is "significant corrosion." Provide a discussion of the inspections performed and actions taken to prevent corrosion.As stated in Section 3.5.2.2.1.4, JAFNPPinspections of the drywell shell below floor level identified no evidence of corrosion of the drywell shell. The drywell shell steel has a coated surface and no degradation of this coating was identified.
The statement in question is not addressing the current condition but rather the conditions expected in the future. It is difficult to say there will be absolutely no corrosion in the future, but there is reasonable assurance that corrosion, if any, will not be significant or meaningful with respect to degradation.

proposed action (4).For JAFNPP, the sand cushion area at the base ofthe drywell is drained to protect the exterior surface of the drywell shell at the sand cushion interface from water that might enter the air gap. To ensure the drywell shell exterior remains dry during refueling evolutions, the drywell to reactor building bellows assembly separates the refueling cavity filled with water from the exterior surface of the drywell shell. Any leakage through the bellows assembly is directed to a drain system which is equipped with an alarm for notification of operators.
Functional checks are performed on the alarmsystem and the air gap drains are monitored twice every refuel outage, once after flood-up and again prior to flood-down at the end of the outage.
JAFNPP inspects the liner drains for the water reservoirs on the refuel floor (e.g., spent fuel pool, dryer/separator pool, and reactor cavity) for leakage. Leakage into the liner drains could be a precursor for water leaks which could wet the drywell shell exterior surface. These drains are examined for leakage after filling the refueling cavity.This item is closed to RAI 3.5.2-1.

Please provide the following information:b.) Describe the scope and aging managementreview performed for Class MC Pressure Retaining Bolting. How is loss of preload managed?JAFNPP has not identified Class MC pressureretaining bolts having a yield stress >150 ksi within the boundaries for structural applications. As a result loss of preload is not an aging effect requiring management.
In general, JAF manages loss of material for bolting with visual inspections. For structural bolting, the visual inspections are part of the Structures Monitoring Program. Loss of preload due to stress relaxation (creep) would only be a concern in very high temperature applications (>
700°F) as stated in the ASME Code,Section II, Part D, Table 4. No JAFNPP structural bolting operates at >700°F. Therefore, loss of preload due to stress relaxation (creep) is not an applicable aging effect for structural bolting. Other causes of loss of preload include inadequate bolted joint design and ineffective maintenance practices. Loss of preload due to these causes is prevented by incorporation of industry guidance for good bolting practices into JAF procedures for design and maintenance of bolted joints.The project team finds the applicant'sresponse acceptable, because the applicant has adequately described how loss of preload is managed. The service temperature for the structural bolting is below the 700°F threshold temperature for initiation of creep-induced stress relaxation, as identified in ASME Code,Section II, Part D, Table 4. Thus, the project team concludes that loss of preload resulting from creep-induced stress relaxation is not an aging effect requiring management for these structural bolts (i.e., Class MC pressure retaining bolts). The applicant manages loss of preloaddue to other causes by incorporation of industry guidance for good bolting practices into JAF procedures for design and maintenance of bolted joints. The project team finds this acceptable.183290Item 3.5.1 In Table 3.5.2-1 on Page 3.5-58of the LRA, for component Bellows, the AMPs shown is CII-IWE, which is a plant-specific AMP.

Concrete within the drywell consist of the reactor pedestal, sacrificial shield wall and the drywell floor. Assurance that bulk concrete temperatures within the drywell remain below 150 degrees F is obtained through maintaining average bulk containment temperature within the limits allowed by JAFNPP Technical Specification Section B3.6.1.5. Although upper elevations of the drywell may exceed 150°F, the concrete of the drywell is at lower elevations. The drywell cooling system provides cooling to ensure temperature limits are not exceeded. The highest concrete in the drywell is the sacrificial shield wall.

As discussed during the November 30, 2006 meeting and during the JAF AMR audit, that bolted connections are the main concern.
The stressors thermal cycling, ohmic heating, and electrical transients are potential stressors only for high load connections.Thermal cycling, ohmic heating, and electricaltransients are not potential stressors for low load connections. Low-load connections located in a controlled environment can be screened out, because vibration, chemical contamination, corrosion and oxidation are not a concern. Low-load in-scope field instrumentation connections such as pressure transmitters, RTDs, and flow transmitters are not subject to AMR, because the in-scope instrumentation located in a harsh environment, are typically EQ, and the non-EQ sensitive instrument circuit (high radiation and neutron monitoring) connections which are included in the XI.E2 program. All connections associated with circuits that do not have an intended function, such as general lighting, are not subject to AMR.Methods To Identify Cable ConnectionsThe methods used to identify cable connections to include in the AMP were based on discussions in the November 30, 2006 NEI meeting with the NRC.
The types of circuits considered for identifying cable connections were electrical and I&C penetrations, DC load centers, inverters, battery chargers, motors, MCCs, switchgear, circuit breakers, transformers, metal-enclosed bus, and field components. All of the electrical and I&C penetrations are EQ; therefore, all of the Question and Answer Database Audit and Review Related to the License Renewal Application for James A.

potential transformers (CTs/PTs), and power supplies. The assumption made for the non-EQ high load connections was that all of these connections are bolted.The basis discusses the stressors that are beingaddressed. Plant information (single line drawings, switchyard drawings) was searched to determine the potential population of bolted connections. The criterion used for determining the high load connections was identifying power circuits for all voltage levels. The types of cable connections that were determined to meet the definition of a high load connection are subject to AMR. In addition to the one-time inspection program, many of the JAFNPP cable connections are inspected or tested by PMs. The maintenance procedures (PMs) for the following components were searched to determine if the PM evaluated the field cable connections associated with the active components.* 480 VAC MCCs and Switchgear (MP-056.01 ACMotor Control Center Maintenance)* 600 VAC MCCs and Switchgear (MP-056.01 AC Motor Control Center Maintenance)* 4160 VAC Switchgear (MP-054.02 4.16kV Bus and Metal-Clad Switchgear)* AC Motors (MP-059.83 Motor Power Monitoring (MPM) Testing and Analysis) DC Motors (MP-059.83 Motor Power Monitoring (MPM)

Include test data and plant specific acceptance criteria for transmission conductor strength in your response.The most prevalent mechanism contributing to lossof conductor strength of an ACSR (aluminum conductor steel reinforced) transmission conductor is corrosion, which includes corrosion of the steel core and aluminum strand pitting. For ACSR conductors, degradation begins as a loss of zinc from the galvanized steel core wires. Corrosion rates depend largely on air quality, which includes suspended particles chemistry, SO2 concentration in air, precipitation, fog chemistry and meteorological conditions. Tests performed by Ontario Hydroelectric showed a 30% loss of composite conductor strength of an 80 year old ACSR conductor due to corrosion.RSST 71T-3 is connected to the 115 kV switchyardwith overhead transmission lines. The overhead transmission conductors are 336.4 MCM ACSR 18/1 conductors with a 7 AWG alumoweld static wire. This specific conductor type was not included in the Ontario Hydroelectric test, but this type isThe project team finds the applicant'sresponse acceptable because test data from Ontario Hydroelectric, which is bounded by the types of conductors at JAFNPP, illustrates that transmission conductors will have ample strength through the period of extended operation.
Based on this information, the staff concludes that loss of conductor strength is not a significant aging effect requiring management at JAFNPP This question is resolved.

No.Audit QuestionsApplicant's ResponseProject Team's Evaluations 125bounded by the types that are included. There is aset percentage of composite conductor strength established at which a transmission conductor is replaced. As illustrated below, there is ample strength margin to maintain the transmission conductor intended function through the period of extended operation.The National Electrical Safety Code (NESC)requires that tension on installed conductors be a maximum of 60% of the ultimate conductor strength. The NESC also sets the maximum tension a conductor must be designed to withstand under heavy load requirements, which includes consideration of ice, wind and temperature. These requirements are reviewed concerning the specific conductors included in the AMR. The conductors with the smallest ultimate strength margin (4/0 ACSR) will be used as an illustration.The ultimate strength and the NESC heavy loadtension requirements of 4/0 (212 MCM) ACSR are 8350 lbs. and 2761 lbs. respectively. The margin between the NESC Heavy Load and the ultimate strength is 5589 lb.; i.e., there is a 67% of ultimate strength margin. The Ontario Hydroelectric study showed a 30% loss of composite conductor strength in an 80 year old conductor. In the case of the 4/0 ACSR transmission conductors, a 30% loss of ultimate strength would mean that there would still be a 37% ultimate strength margin between what is required by the NESC and the actual conductor strength. The 4/0 ACSR conductors have the lowest initial design margin of transmission conductors included in the AMR. This illustrates with reasonable assurance thattransmission conductors will have ample strength through the period of extended operation.

The OE report did not identify any failures of switchyard connections due to aging. The typical design of switchyard bolted connections includes Bellville washers and is no-ox coated. The type of bolting plate and the use of Bellville washers is the industry standard to preclude torque relaxation.
This combined with the proper sizing of the conductors virtually eliminates the need to consider this aging mechanism, therefore, there will be noThe project team finds the applicant'sresponse acceptable because the design of transmission connections using Bellville washer will eliminate the potential torque relaxation of bolted connections. The use of anti-oxidant compound will prevent the formation of oxides on the metal surface and to prevent moisture entering the connections thus reducing the chances of corrosion. This question is resolved.

No.Audit QuestionsApplicant's ResponseProject Team's Evaluations 127significant aging. The in-scope transmission conductors at JAFNPP are limited to the connections from the 115 kV switchyard to the station service transformer for the SBO recovery path. JAFNPP performs infrared inspection of the 115 kV switchyard connections as part of a PM task that is performed at least once each year.. This PM and the absence of plant OE confirms that no significant aging is occurring for JAFNPP. Based on this information, torque relaxation of transmission connections does not require aging management for JAFNPP.Loss of material due to corrosion of connectionsdue to surface oxidation is an applicable aging mechanism, but is not significant enough to cause a loss of intended function. The components in the switchyard are exposed to precipitation, but these components do not experience any appreciable aging effects in this environment, except for minor oxidation, which does not impact the ability of the connections to perform their intended function. At JAFNPS, switchyard connection surfaces are coated with an anti-oxidant compound (i.e., a grease-type sealant) prior to tightening the connection to prevent the formation of oxides on the metal surface and to prevent moisture from entering the connections thus reducing the chances of corrosion. Based on operating experience, the method of installation has been shown to provide a corrosion resistant low electrical resistance connection. In addition, the infrared inspection of the 115KV switchyard verifies that this aging effect is not significant for JAFNPP.
Therefore, it is concluded that general corrosion resulting from oxidation of switchyard connection surface metals does not require management at JAFNPP.

Explain why transmission conductor vibration or sway would not cause a loss of intended function if left unmanaged for the extended period of operation.Transmission conductor vibration, or sway, wouldbe caused by wind loading. Wind loading that can cause a transmission line and insulators to vibrate is considered in the design and installation.

This appears to conflict with information in LRA Table 4.3-1 which identifies that the "Core Shroud Support" is the limiting Class 1 component (and therefore limiting RV internal) for CUF (with a 40-year CUF value of 0.90). Clarify which Class 1 component analyzed in accordance with ASME Section III CUF methodology is the limiting CUF component for fatigue and state what the 40-year, non-environmentally impacted CUF value for this component (i.e.,

Confirm that the 40-year CUF value provided for the jet pump diffuser adapter in LRA Section 4.3.1.2 appropriately supplements the 40-year CUFs for the commodity groups that are provided in LRA Table 4.3-1.The jet pump assembly diffuser adapter is not aClass 1pressure boundary component. Therefore, its CUF is not listed among the maximum CUFs for Class1 components in Table 4.3-1. The core shroud support is welded into the reactor vessel by the vessel manufacturer, and is analyzed for CUF as part of the reactor vessel stress report. Since the vessel is a Class 1 component, the attached core shroud support CUF is included in the Class 1 component CUFs in Table 4.3-1.The highest (most limiting) CUF for the reactorvessel, based on the analyzed number of design transients, prior to any environmentally assisted fatigue adjustment, is 0.90 for the shroud support.

In accordance with the guidelines of NUREG-1801, the commodity groups in Table 3.1.2-3 are grouped based on material and environment, not on design code. Therefore these entries may represent multiple design codes. To answer this question, the components must be reviewed on a component by component basis, not a commodity group basis.The RCSPB components in question are:* Fatigue is not an aging effect requiringmanagement for the stainless steel control rod drive mechanisms (pressure boundary) because they are maintained below the 270 degree F threshold for fatigue of stainless steel.*The control rod drive accumulators are not subjectto fatigue as they never exceed 140 °F.*The control rod drive scram discharge header hascomponent IDs of 03TK-1A and 03TK-1B; however, these "tanks" actually consist of sections of large diameter piping inserted into the scram discharge piping. All the scram discharge piping, including the scram discharge headers are built to ANSI B31.1. It will not exceed 7000 cycles and therefore remains acceptable for the period of extended operation.*The reactor recirculation pump (driver mount, casing, cover, and thermal barrier) are not built to ASME Section III and no fatigue analyses for these parts were found. The driver mount is not exposed to hot water and therefore is not susceptible to fatigue. Cracking of the casing and cover (including thermal barrier) is managed by a combination of Water Chemistry Control, Inservice Inspection, and BWR Stress Corrosionfatigue-induced damage is an applicableaging effect for the components.

Cracking, due to both SCC and fatigue, of these components is managed by the One-Time Inspection Program.200315Section 4.3.2 of the JAFNP LRA providesEntergy's TLAA on Metal Fatigue of Non-Class 1 components. In this section Entergy provides the metal fatigue analysis for the Non-Class 1 components that were designed in accordance with B31.1. For each non-piping components/commodity group in AMR Tables 3.2.2-X, 3.3.2-X and 3.4.2-X that is within the scope of a fatigue-based AMR line item, identify which design code applies to the particular commodity group and clarify whether the design code required a metal fatigue analysis.

If a metal fatigue analysis was not performed and "cracking -fatigue" needs to be manage for the EPO, propose an acceptable AMP for the management of the aging effect in accordance with the criterion in 10 CFR 54.21(c)(1)(iii).The piping and in-line components in Tables 3.2.2-X, 3.3.2-X and 3.4.2-X, including cyclone separators, drain pots, expansion joints, flow elements, mufflers, orifices, piping, rupture disks, steam traps, strainers, strainer housings, thermowells, T-quenchers, tubing and valve bodies are identified with a TLAA for fatigue, and are discussed in Section 4.3.2 of the LRA. These components were designed to the applicable ASME Section III, Section VIII or ANSI B31.1 code.
Since the TLAA remains valid per 10CFR54.21(c)(1)(I), no aging management program is required to manage cracking due to fatigue. For those components In Tables 3.2.2-X, 3.3.2-X,and 3.4.2-X, that were not designed to any ASME or ANSI code, cracking-fatigue, as an aging effect, will be managed by the applicable aging management program; One-Time Inspection, Fire Protection, or Periodic Surveillance and Preventive Maintenance (PSPM). These components are on air or exhaust systems and since no design code applies, review for a TLAA is not applicable.The project team finds the applicant'sresponse acceptable because the applicant has identified: (1) those Non-Class 1 components that were built to ASME Section III or VIIII or ANSI B31.1, or to Codes other than ASME Sections III or VIII or ANSI B31.1, (2) whether fatigue-induced damage is an applicable aging effect for these components, and (3) what type of TLAAs or AMPs will be used to manage fatigue-induced damage in these components, if fatigue-induced damage is an applicable aging effect for the components.

On pages 4.3-7 and 4.3-8, Entergy provides its corrective action plan to address this issue. The corrective action program for the environmentally impacted CUF factor components (i.e., the Class 1 components at JAFNP that correspond to those analyzed for fatigue in NUREG/CR-6260) needs to be included as a commitment on the JAFNP LRA.LRA Table 4.3-2 is for projected cycles, Table 4.3-3is for environmentally adjusted CUFs. Note that Table 4.3-3 does not indicate that 40 year CUFs will exceed 1.0 with the EAF adjustment because the EAF adjustment is not applied until the period of extended operation. However, some of the CUFs will exceed 1.0 at the beginning of the period of extended operation when environmentally assisted fatigue is added to the CUF calculation.

This includes applying the appropriate Fen factors to valid CUFs determined in accordance with one of the following.1. For locations, including NUREG/CR-6260locations, with existing fatigue analysis valid for the period of extended operation, use the existing CUF to determine the environmentally adjusted CUF.

The fatigue analysis of the SRV piping along with all the other torus attached piping. (TAP) is bounded by Mark 1 Upgrades generic report MPR-751, prepared by GE. MPR-751 concluded that for all plants and piping systems considered, in all cases the fatigue usage factors for an assumed 40-year plant life was less than 0.5. In a worst-case scenario, extending plant life for an additional 20 years would produce usage factors below 0.75. Since this is less than 1.0, the fatigue criteria are satisfied. The MPR-751 generic fatigue analysis is thus protected for the period of extended operation in accordance with 10 CFR 54.21(c)(1)(ii)A JAF plant specific analysis addresses the SRVdischarge piping and its supports, as well as the main vent penetration through which the SRV discharge enters the torus. This analysis states that the SRV penetrations are qualified for 7500 cycles of maximum load while the SRVs are expected to see less than 50 cycles at maximum load and less than 4500 cycles at partial load. The TR-5321-2 report concludes "Since the 7500 cycles of maximum load bounds both of these by such a large margin and since no other significant loads are imposed on the line, the penetration was assumed acceptable for fatigue without further evaluation." Increasing the 40 year cycles by 1.5 for the period of extended operation would still be only 75 maximum load cycles and 6750 low load cycles for a total of 6850 mixed load cycles, less than the 7500 maximum load cycles permitted.

The results of the generic GE Mark 1 containment program (based on 40 years of operation) were that 92% of the TAP would have cumulative usage factors of less than 0.3, and that 100% would have usage factors less than 0.5. Conservatively multiplying the CUFs by 1.5 shows that for 60 years of operation, 92% of the TAP would have CUFs below 0.45, and 100% would have CUFs below 0.75.

In the ANSI B31.1 code, fatigue is addressed by using stress range reduction factors to reduce the stress allowable (SA). The LRA states that since the RCPB components will not exceed 7000 full temperature cycles in 60 years of operation, the existing stress analyses remain valid for the period of extended operation, in accordance with 10 CFR 54.21(c)(1)(I). However, LRA Section 3.1.2.2.1 states exceptions for the steam line flow restrictors and reactor water circulating pumps, which also require no fatigue analysis. The One-Time Inspection Program is credited to manage cracking due to fatigue for the main steam line flow restrictors, and the ISI Program is credited for the reactor water circulating pumps. In LRA Table 3.1.1, items 3.1.1-55 and 3.1.1-57, the same AMPs are also credited to manage loss of fracture toughness due to thermal aging embrittlement for these two RCPB components. Please provide the following information:a) Clarify why exceptions are taken for thesteam line flow restrictors and the reactor water circulating pumps.There was no Code exception taken for the mainsteam flow restrictors or for the reactor water recirculation pumps. The exception for the main steam flow restrictors and the reactor water recirculation pumps indicates that the JAFNPP design codes (code of record) for these components did not require a fatigue analysis.
Consequently, cracking due to fatigue has no TLAA for JAFNPP. There is only one line entry for cracking for these components; a line entry that includes cracking due to any applicable mechanism. Cracking due to fatigue will be managed by the same programs that manage cracking due to other mechanisms.Cracking and loss of fracture toughness of themain steam flow restrictors will be managed by the One-time Inspection Program.The flow restrictors are not pressure boundaryparts and as such are not covered by the ISI Program.
One-time inspection is considered adequate for the main steam flow restrictors as they are not pressure boundary parts. Cracking and loss of fracture toughness of therecirculation water pump casings are managed by the Inservice Inspection Program.The pump casing welds are examined per IWB-2500-1 Category B-L-1 while the pump casing itself is examined per IWB-2500-1 Category B-L-2.The project team finds the applicant'sresponse to be acceptable based on the following justifications/bases:(1) The flow restrictors are not ASMESection III or ANSI B31.1 pressure boundary components; it is acceptable to use a one-time examination to inspect for any cracking that may be induced by fatigue, as fatigue-induced cracking is not expected to occur in these components.(2) The Class 1 piping at JAFNPP wasdesigned to ANSI B31.1 not to ASME Section III. The recirculation pumps would be designed in accordance with some other Code other than ANSI B31.1 or ASME Section III and the Code of Construction may not have required a fatigue analysis for the pump casings.
Therefore, it is acceptable to use the ASME Section XI, Table IWB-2500-1 Category B-L-1 and B-L-2 requirements as a basis for managing any cracking in the pump casings that may be induced by fatigue. This question is resolved.

This question is resolved.211327The further evaluation in LRA Section 3.1.2.2.2,item 2, and the discussion column in Table 3.1.1, item 3.1.1-13, states that, although JAFNPP does not have an isolation condenser, loss of material due to general, pitting, and crevice corrosion for other steel components exposed to reactor coolant will be managed by the Water Chemistry Control - BWR Program and the One-Time Inspection Program. SRP Section 3.1.2.2.2, item 2, recommends the water chemistry program and an augmented inspection program for the management of loss of material due to general, pitting, and crevice corrosion for both steel and stainless steel isolation condenser components. Please provide the following information:b) Discuss the evaluation performed toconclude that the activities in the one-time inspection AMP are consistent with theSRP Section 3.1.2.2.2, Item 2 states, "A one-timeinspection of select components at susceptible locations is an acceptable method to determine whether an aging effect is not occurring or an aging effect is progressing very slowly such that the component's intended function will be maintained during the period of extended operation. Activities of the One-Time Inspection Program include combinations of nondestructive examinations (including visual, ultrasonic, and surface techniques) that will be performed by qualified personnel following procedures that are consistent with Section XI of ASME B&PV Code and 10CFR50, Appendix B. As described in LRA Appendix B, the elements of the One-Time Inspection Program include (a) determination of the sample size based on an assessment of materials of fabrication, environment, plausible aging effects, and operating experience; (b) identification of the inspection locations in the system or componentLoss of material due to pitting and crevicecorrosion could occur in stainless steel BWR isolation condenser components exposed to reactor coolant. Loss of material due to general, pitting, and crevice corrosion could occur in steel BWR isolation condenser components.
The existing program relies on control of reactor water chemistry to mitigate corrosion. However, control of water chemistry does not preclude loss of material due to pitting and crevice corrosion at locations of stagnant flow conditions. Therefore, the effectiveness of the chemistry control program are verified to ensure that corrosion is not occurring.
The GALL Report recommends further evaluation of programs to verify the effectiveness of the chemistry control program.

The AMR credits the Water Chemistry Control - BWR program and either the BWR Penetrations, BWR Vessel Internals or Inservice Inspection Program. NUREG-1801 recommends the BWR Penetration and Water Chemistry programs. Please discuss the evaluation performed to conclude that the activities in the BWR Vessel Internals and Inservice Inspection AMP are consistent with the activities in the BWR Penetration AMP recommended by NUREG-1801 for the components addressed by this AMR, including the activities performed to manage aging, the sample population inspected, and the inspection locations.The only variances from NUREG-1801 in LRAtables 3.1.2-1, 3.1.2-2 and 3.1.2-3 items referencing 3.1.1-40 are for the CRD stub tubes and the incore housings.Although NUREG-1801 Section IV calls for theBWR Penetrations Program to manage cracking of the CRD stub tubes and the incore housings, the BWR Penetration Program described in NUREG-1801, XI.M8 does not address either of these components. Therefore, JAFNPP did not credit the BWR Penetrations Program for managing this cracking.Cracking of the CRD stub tubes is managed by theBWR Vessel Internals Program, which incorporates the guidelines of NRC approved BWRVIP-47A for the CRD stub tubes. The BWR Vessel Internals Program has been reviewed for consistency with GALL and the applicable BWRVIPs and there are no exceptions to BWRVIP-47A.Cracking for the incore housings is managed by theInservice Inspection Program. We will modify the LRA to show this cracking is also managed by the BWR Vessel Internals Program. Similar to the CRD stub tubes, the BWR Vessel Internals Program includes the BWRVIP-47A recommendations for the incore housings without exception.ISI performs volumetric or surface examination of10% of the peripheral CRD housing welds. InThe project team finds the applicant'sresponse to be acceptable. The CRD stub tubes are not treated as vessel attachments which contain portions internals to the reactor vessel. BWRVIP-47A provides the BWRVIP's inspection and flaw evaluation guidelines for the reactor vessel internal lower plenum components. The CRD stub tubes and incore housings are reactor vessel internal low plenum components. Thus, the BWR Vessel Internals and BWRVIP-47A are appropriate programs to credit for managing cracking due to IGSCC, SCC or cyclical loading in the CRD stub tubes and incore housings. The applicant also credits its ISI program to manage these aging effects in the incore housings. The ISI program calls for a volumetric or surface examination of 10% of the incore housing welds. This is acceptable. The applicant made the applicable amendment of the LRA in LRA Amendment No. 5, dated February 1, 2007. This question is resolved.

For some components of the reactor vessel and reactor coolant pressure boundary, the LRA credits the BWR Stress Corrosion Cracking and Water Chemistry Control - BWR AMPs to manage cracking, further supplemented by the Inservice Inspection Program, which is Consistent with NUREG-1801. For other components, to which the BWR Stress Corrosion Cracking Program is not applicable, cracking is managed by the Water Chemistry Control - BWR Program, and either the Inservice Inspection, One-Time Inspection, BWR Feedwater Nozzle or BWR Vessel Internals Program. Please identify the components to which the BWR Stress Corrosion Cracking Program is not applicable and discuss the evaluation performed to conclude that the activities in the Inservice Inspection, One-Time Inspection, BWR Feedwater Nozzle or BWR Vessel Internals AMPs are consistent with the activities in the BWR Stress Corrosion Cracking AMP recommended by NUREG-1801 for the components addressed by this AMR, including the activities performed to manage aging, the sample population inspected, and the inspection locations.The BWR Stress Corrosion Cracking Program isapplicable to stainless steel reactor vessel nozzle safe ends greater than 4" NPS (core spray, jet pump instrument, and recirc inlet/outlet nozzles);
RWR flow elements, pump casings and covers; and piping, fittings and valve bodies of the RCPB that are greater than 4" NPS. The BWR Stress Corrosion Cracking Program is not applicable to any other components. The feedwater, core spray, and RWR nozzle thermal sleeves are not part of the BWRSCC program because they are not part of the Code-required pressure boundary. The thermal sleeves employ press-fit or threaded connections.The ISI Program was evaluated as a plant-specificprogram; the One-Time Inspection Program was evaluated for consistency with the NUREG-1801 One-Time Inspection and Small-bore Piping AMPs; the BWR Feedwater Nozzle Program was evaluated for consistency with the NUREG-1801 BWR Feedwater Nozzle AMP; and the BWR Vessel Internals Program was evaluated for consistency with the NUREG-1801 BWR Vessel Internals AMP. Each of these programs was determined effective at managing the aging effects noted for the associated material and environment combinations. Note E was used in Tables 3.1.2-1 and 3.1.2-3 in all of these cases because a different program than the one identified in item 3.1.1-41 is credited for aging management.The project team finds the applicant'sresponse to be acceptable. The BWR Stress Corrosion Cracking Program is based on recommendations of NUREG-0313, Revision 2, and GL 88-01, as modified through staff approval of guidelines in BWRVIP-75A, and is only applicable to piping, piping elements, and pipe fittings made from stainless steel.
The response clearly clarifies that the thermal sleeves for the feedwater inlet, core spray, and recirculation inlet (RWR) piping penetrations are not welded components and thus are not within the scope of Class piping welds covered under the NUREG-0313 recommendations. Table 3.1.2-1 of the LRA is clear the applicant credits the BWR Feedwater Program for the application is clear for the feedwater inlet thermal sleeve and the BWR Vessel Internals Program for the core spray and recirculation inlet nozzles.

The LRA states that the One-Time Inspection Program will verify the effectiveness of the Water Chemistry Control Program to manage loss of material. The LRA also states that the Inservice Inspection Program is not applicable to most reactor vessel internal components since they are not part of the pressure boundary. Please identify the reactor vessel internals that are part of the pressure boundary and, therefore, are subject to Inservice Inspection. For those components, please clarify why Inservice Inpsection is not credited for this AMR.

As described in LRA Section 2.3.1 (pages 2.3.1&2), the incore flux monitor guide tubes extend from the top of the incore flux monitor housings, in the lower plenum, to the top guide.
The power range detectors for the power range monitoring units and the dry tubes for the source range monitoring and intermediate range monitoring (SRM/IRM) detectors are inserted through the guide tubes. These components inside the reactor vessel are, via the housings in the lower plenum, connected to penetrations in the reactor vessel and, therefore, are a part of the reactor coolant pressure boundary. Even though JAFNPP is performing all the inservice inspections required by Section XI of the ASME code, JAFNPP is not crediting the Inservice Inspection Program for the management of aging for these components due to their location inside the reactor vessel. The One-Time Inspection Program, which is credited for these components inside the vessel, has not been evaluated for consistency with the NUREG-1801 Inservice Inspection (ISI) AMP, but instead was evaluated for consistency with the NUREG-1801 One-Time Inspection and Small-bore Piping AMPs.
A Note E was used in Table 3.1.2-2 because a different program than the one identified in item 3.1.1-47 is credited for aging management.JAFNPP performs all the inspections required bythe ASME Section XI Inservice Inspection Program, but this program is not credited for managing loss of material because it does not specifically inspect many of the reactor vessel internal components.
JAFNPP credits the BWR Vessel Internals Program which incorporates the requirements of ASME Section XI, the approved BWRVIP3.1.1-47, as given in LRA Amendment No.5, dated February 1, 2007. In this LRA amendment, the applicant amended LRA Item 3.1.1-47 to credit the BWRVIP Vessel Iternals Program, in addition to the Water Chemistry Program and the One-time Inspection Program, as the basis for managing loss of material due to crevice or pitting corrosion in nickel alloy and stainless steel BWR RV internal components. The BWR Vessel Internals Program prescribes augmented inspections proposed by the BWRVIP and approved by the staff for the vessel internal components. The BWRVIP inspections for RV and RV internal components include and go beyond the inservice inspections for RV and RV internal components that are required in accordance the ASME Code Section XI.

The JAFNPP BWR Vessel Internals program includes the visual examinations required by ASME Section XI as well as any other requirements found in approved BWRVIP documents, and other industry documents.
JAFNPP has credited the BWR vessel internals program rather than ISI because BWR vessel internals is the governing program for management of the vessel internals.The project team finds the applicant'sresponse to be acceptable because the response clarifies that the BWR Vessel Internals Program is the program that is credited to manage cracking in the core shroud and core plate welded access hole cover in lieu of the ISI Program. The BWRVIP Vessel Internals Program prescribes augmented inspections for the vessel internals that include and go beyond the requirements of Section XI.
During the project team's AMR audit performed in December 2006, the applicant provided the audit team with a plant diagram of the welded access hole cover. The diagram provided sufficient evidence of the weld configuration for the access hole cover did not create a creviced region behind the weld. Thus, the project team concludes that no augmented UT is necessary for the access hole cover weld, as would otherwise be recommended by GALL AMR Line Item IV.B1-5 (i.e. Item R-94) if the weld configuration were to create creviced region behind the weld.

Please confirm that JAFNPP does not have any steel or low alloy carbon steel RCPB bolting.first sentence of the discussion for LRA Table3.1.1, item 3.1.1-52, is specific to stainless steel bolting. The remaining discussion addresses both stainless steel and low alloy steel (or similar material).Also, due to more applicable aging mechanisms forloss of material (e.g., general, crevice and pitting corrosion) and SCC not being applicable to alloy steel bolting that is not high-strength, the low alloy steel, carbon steel RCPB bolting was compared to a NUREG-1801 item (V.E-4), which corresponds to NUREG-1800 item 3.2.1-23, and a Note C is used in Table 3.1.2-3.steel and steel (i.e., low alloy steel orcarbon steel) bolting.

The LRA credits the Bolting Integrity AMP to manage these aging effects, which is consistent with NUREG-1801 recommendations. Please provide the following information:b) The LRA states that industry operatingexperience indicates that loss of material due to wear is not a significant aging effect for bolting. Please provide the technical justification and the operating experience data to support this conclusion.Loss of material due to wear is not a significantaging effect for RCPB bolting because wear is the result of relative motion between two surfaces and any relative displacements or movements during normal plant operations are small and the resulting loss of material minimal. The relative motion between bolting and the connected surface that can occur during periodic assembly/disassembly for inspection maintenance are not related to normal aging. As described in LRA Table 3.1.1, item 3.1.1-52, occasional thread failures, such as galling (or improper fitup/assembly), are event driven conditions that are resolved as required.
Therefore, loss of material due to wear of RCPB bolting, both stainless steel and low alloy steel, carbon steel, is not a significant aging effect.Industry operating experience documented invarious sources, such as the Non-Class 1 Mechanical Implementation Guideline and Mechanical Tools, Revision 3, EPRI, Palo Alto, CA:
2001. 1003056 (Mechanical Tools), supports that the most common failures of pressure retaining bolting in safety-related applications were attributedThe project team finds the applicant'sresponse to be acceptable. GALL TableIV.C1 includes AMR items IV.C1-12 and -13 that specify that loss of material due to wear may be an applicable aging effect for bolting in Class 1 pumps or valves. While the response indicates that the applicant does not consider loss of material to be an issue for its Class 1 bolting, it is clear from the AMR Item on bolting in LRA Table 3.1.2-3 that the applicant is crediting the Bolting Integrity Program to manage mechanisms that can lead to loss of material in the steel bolting for its Class 1 pumps and valves. This would cover any loss of material by wear and is consistent with the GALL. The ASME Section XI requirements discussed in the [Detection of Aging Effect] program element of GALL AMP XI.M18, "Bolting Integrity," are considered to be sufficient to manage loss of material in this bolting.

No instances of bolting wear have been identified in site or industry documentation that were attributable to normal aging, whereas event driven bolting failures are known to occur, and are corrected in the short-term. Furthermore, the operating experience discussion for the Bolting Integrity Program in NUREG-1801, Revision 1,Section XI.M18 does not address bolting wear as an aging mechanism for bolting.221337LRA Table 3.1.1, item 3.1.1-52, addressescracking due to SCC, loss of material due to wear, loss of preload due to thermal effects, gasket creep and self-loosening for RCPB bolting in high-pressure and high temperature systems. The LRA credits the Bolting Integrity AMP to manage these aging effects, which is consistent with NUREG-1801 recommendations. Please provide the following information:c) The LRA states that loss of preload is adesign driven effect and not an aging effect requiring management. Please provide the technical justification for concluding that thermal cycles, gasket creep and self-loosening are not aging mechanisms that could lead to this aging effect.As described in LRA Table 3.1.1, item 3.1.1-52,loss of preload would only be a concern in very high temperature applications (> 700ºF), per ASME Code Section II, Part D, Table 4. No JAFNPP systems operate at > 700ºF so no JAFNPP bolting is exposed to the high temperatures that could result in a loss of preload. At elevated temperatures (thermal effects), a fastener will produce less and less clamping force with time, referred to as relaxation. A bolted joint at 1200ºF can lose as much as 50% of preload.Furthermore, elevated temperature behavior, e.g.,where relaxation might occur, begins at 700ºF for low alloy steels, and higher for austenitic stainless steels (Ref. Volume 11 of the Metals Handbook, 9th Edition, "Failure Analysis and Prevention).
Gasket creep and self-loosening, that are not a product of thermal effects, typically occur shortly after initial loading and early in the service life with actions taken to prevent recurrence.The project team finds the applicant'sresponse to be acceptable as the JAFNPP operates at approximately 550F and1000 psig pressure and the applicant has used an applicable materials source document to screen whether its Class 1 low alloy steel bolting for loss of preload due to stress relaxation.

The applicant's implementation of the Bolting Integrity for the Class 1 steel bolting at JAFNPP should be sufficient to detect any loss of preload that may occur in this bolting. This question is resolved.223339LRA Table 3.1.1, item 3.1.1-55, addresses lossof fracture toughness due to thermal aging embrittlement in CASS Class 1 pump casing and valve bodies and bonnets exposed to reactor coolant.The LRA credits the ISI for pumps and One-Time Inspection for valves to manage this aging effect. Please clarify whether JAFNPP will use ASME Code Case N-481 as an alternative for pump casing. Also, please clarify why One-Time Inspection is credited for valves.ASME Code Case N-481 is not applicable to theJAF ISI Program for reactor recirculation Pump Casings.JAF has no welds in the recirculation pump casing.The ISI program is applicable for Valve bodies > 4" for visual examination of internal surfaces, pressure testing and leak testing. This is credited for managing aging effects.Valves 4" have no required NDE inspectionsunder the ASME Section XI Code or the ISI program, but are required to be visually inspected (VT-2) in accordance with the pressure testing program conducted every refuel outage. This visual inspection requirement also applies to Pump Casings because they are included in the pressure testing program.The project team finds the applicantsresponse to be acceptable with the exception that states the ASME Section XI does not include any NDE requirements for Class 1 valves less than 4 inches NPS.

Subsequent to the audit, the applicant stated that it will amend the LRA Table 3.1.2 .3 for line item 3.1-55 to add the ISI program along with one -time inspection program to manage the reduction of fracture toughness for valve bodies <4" NPS, with CASS material.

The project team's review is discussed in SER Section 3.1.2.1.6. This question is resolved. 224340LRA Table 3.1.1, item 3.1.1-57, addresses lossof fracture toughness due to thermal aging embrittlement in CASS Class 1 piping component, and piping elements and CRD pressure housings exposed to reactor coolant.
The LRA credits the One-Time Inspection AMP to manage this aging effect for the main steam flow restrictors, which are the only CASS component in the scope of this AMR. NUREG-1801 recommends the Thermal Aging Embrittlement of CASS program. Please discuss the evaluation performed to conclude that the activities in the One-Time Inspection AMP are consistent with the activities in the Thermal Aging Embrittlement of CASS AMP recommended by NUREG-1801 for the components addressed by this AMR, including the activities performed to manage aging, the sample population inspected, and the inspection locations.The One-Time Inspection Program has not beenevaluated for consistency with the NUREG-1801 Thermal Aging Embrittlement of CASS AMP, but was instead evaluated for consistency with the NUREG-1801 One-Time Inspection and Small-bore Piping AMPs. A Note E was used in Table 3.1.2-3 because a different program than the one identified in item 3.1.1-57 is credited for aging management.
The One-Time Inspection Program will detect cracking that is symptomatic of reduction of fracture toughness using established visual nondestructive examination (NDE) techniques.
Reduction of fracture toughness does not cause cracking, but the reduced toughness allows existing cracks to propagate at higher rates. Thesample population includes all of the main steam flow restrictors. NUREG-1801 XI.M12 program is applicable to primary pressure boundary and reactor vessel internal components.The project team finds the applicant'sresponse to be acceptable as the main steam flow restrictors are not Class 1 reactor coolant pressure boundary components. The project team concludes that a one-time examination of the main steam flow restrictors is sufficient to determine whether cracking has occurred in the components. Consistent with the basis in GALL for Class 1 pump casings and valve bodies made from CASS as given in the NRC letter (i.e., Chris Grimes letter) to NEI dated, May 19, 2000, the staff's position is that loss of fracture toughness due to thermal aging needs to be addressed in the main steam flow restrictors if the one-time examination indicates the cracking has occurred in the components. This question is resolved.225341LRA Table 3.1.2-1 includes a line item onreactor vessel external attachments that addresses the loss of material of structural low alloy and carbon steel exposed to an air-indoor (external) environment. The LRA credits the ISI AMP for managing this aging effect. Generic note H is cited, indicating that this aging effect is not addressed in NUREG-1801. Please discuss the specific ISI AMP activities that will be performed to manage this aging effect.The ISI Program manages loss of material forreactor vessel external attachments by surface examination using NDE techniques specified in ASME Section XI, Subsection IWB; specifically IWB-2500 category B-K. The current inspection frequency is once an interval (10yrs) on the recommended sample size of 100% of the total population.The project team finds the applicant'sresponse to be acceptable because the applicant has clarified which ASME Section ISI Category and examination method is used to monitor for loss of material in the reactor vessel external attachments. The surface examinations mandated by the ASME Code Section XI, Examination Category B-K requirements are sufficient to monitor for and detect any indications of surface-induced loss of Question and Answer Database Audit and Review Related to the License Renewal Application for James A.

This question is resolved.226342LRA Table 3.1.2-1 includes a line item onreactor vessel closure flanges that addresses the loss of material of high-strength low-alloy steel exposed to an air-indoor (external) environment. The LRA credits the Reactor Head Closure Studs AMP for managing aging of this component. Generic note H is cited, indicating that this aging effect is not addressed in NUREG-1801. Please discuss the specific activities in the Reactor Head Closure Studs AMP that will be performed to manage this aging effect.As stated in LRA Section B.1.23, the Reactor HeadClosure Studs Program is consistent with the program described in NUREG-1801,Section XI.M3, Reactor Head Closure Studs. (There is one exception but it is not related to wear detection.) As stated in NUREG-1801,Section XI.M3, under Detection of Aging Effects, inspection can reveal cracking, loss of material due to corrosion or wear, and leakage of coolant. Specifically, visual inspections specified in ASME Section XI, Table IWB-2500-1 detect loss of material.The project team finds the applicant'sresponse to be acceptable based on the determination that the program attributes for the applicant's Reactor Head Closure Studs, as defined in the bases document for AMP B.1.23, were consistent with those recommended in GALL AMP XI.M3 and provided a sufficient summary of the activities that will be performed to manage both loss of material and cracking in the reactor vessel closure studs and their assembly components. This question is resolved.227343LRA Table 3.1.2-1 includes two line items toaddress the reactor vessel closure flange leakoff nozzle; one line item addresses stainless steel and the other carbon steel.
Please clarify with sketches how the reactor flange leakoff nozzle at JAFNPP has components made out of these two different materials.The reactor vessel flange leak detection systemconsists of lines attached to two separate drilled penetrations in the vessel flange, one between the reactor vessel O-rings and one outside of the outer O-ring. Therefore, materials for the reactor vessel closure flange leakoff nozzles were based on the connecting piping material specifications. The connecting piping for nozzle N13 was identified as stainless steel (A376 Type 304), and for nozzle N14, carbon steel (A106 Grade B).The project team finds the applicant'sresponse to be acceptable because the applicant has clarified which materials and specifications were used to fabricate the two flange leak-off lines; sketches are not necessary for the project team's determination, since the material specifications are sufficient to designate the material types for these lines. This question is resolved.228344LRA Table 3.1.2-3 includes line items toaddress cracking for various components (including condensing chambers, CRD, CRD filter housing, instrumentation orifices, etc.)

However, all line items refer to Table 1 item 3.1.1-48, which credits the Water Chemistry Control - BWR, Inservice Inspection and One-Time Inspection AMPs for managing cracking in stainless steel RCPB components. Please clarify these discrepancies where only two out of three AMPs are credited for RCPB components.items (Condensing chambers, CRD filter housings,and Orifices) that do not currently have this program. This will make 8 of the 9 entries list all 3 programs and be consistent with GALL entry IV.C1-1. Note that these entries will retain a note E because the JAFNPP ISI program is considered a plant specific program.
There was no GALL line that made a good comparison for the Control Rod Drives. JAFNPP decided that IV.C1-1 was the closest GALL line item and therefore used it for comparison.
However, because the drives are not small bore piping, the One-Time Inspection for ASME Code Class 1 Small Bore Piping does not apply to the drives. The CRDs are inspected by ISI in accordance with ASME Section XI, and therefore the ISI program is credited. The note for this entry is E, both because the OTI Small Bore program is not listed and because the ISI program is plant specific.Note 107: The program credited in NUREG-1801,IV.C1-1 is the One-Time Inspection of ASME Code Class 1 Small Bore Piping, not the One-Time Inspection to verify the effectiveness of Water Chemistry Control. GALL item IV.C1-1 does not call out the One-time inspection to verify water chemistry control, consequently JAFNPP did not add Note 107 as the nine entries calling out IV.C1-1 are consistent with that GALL item without OTI for WCC verification.Program. Also, cracking of the control roddrive unit pressure boundary components are managed by the Water Chemistry Control-BWR Program and the Inservice Inspection Program.During the audit and review, the applicantcommitted to amend the LRA to add the Inservice Inspection Program to the AMRs for components condensing chambers, CRD filter housings and orifices. In February 01, 2007, the applicant amended LRA Table 3.1.2-3, for AMRs that reference line Item 3.1.1-48, to add the Inservice Inspection Program to the AMRs for condensing chambers, CRD filter housings and orifices. The team finds this LRA amendment acceptable since it will make these AMRs consistent with the recommendations in the GALL Report.For the AMR line items addressing theCRD units, the applicant stated that since these components are not small bore piping, the One-Time Inspection Program does not apply. Therefore, the Inservice Inspection Program along with the Water Chemistry Control-BWR Program are adequate to manage cracking. The project team reviewed the applicant's Inservice Inspection Program and found that this AMP includes periodic inspections that will be effective for detecting cracking in the CRD units. The team finds that the applicant's Inservice Inspection Program along with the Water Chemistry Control-BWR Program, will provide adequate assurance that cracking due to SCC, IGSCC, and IASCC will be managed Question and Answer Database Audit and Review Related to the License Renewal Application for James A.

On this basis, the team finds the AMR results for this line item acceptable.This question is resolved.229345LRA Table 3.1.2-2 includes a line item toaddress cracking of the reactor top guide assembly. The LRA credits the Water Chemistry Control-BWR, BWR Vessel Internals, and One-Time Inspection AMPs to manage this aging effect. The description of the BWR Vessel Internals program in Section B.1.7 of the LRA includes an exception stating that the inspection of the hold-down assemblies of the top guide at 0degree and 180degree are deferred from RO16 to RO17. NUREG-1801 recommends augmented inspections for top guides with neutron fluence exceeding the IASCC threshold (5E20. E>1MEV) before or after entering the period of extended operation.

In that, JAF has been inspecting the hold down assemblies despite BWRVIP-26-A (A version approved by the NRC),
Figure A-1 showing that the FitzPatrick plant faulted vertical loads at hold-down assemblies are on the demarcation line between "lift off" and "will not lift". Therefore, the hold down assemblies will not lift-off during a postulated seismic event.Accessible areas of top guide hold-downassemblies at 0° and 180° were inspected in R17 (Fall 2006) by VT-1 visual method with no recordable indications noted. R17 inspections also included top guide grid beam and beam-to-beam crevice slot at three locations by VT-3/VT-1 with no recordable indications noted.The project team finds the applicant'sresponse acceptable because the applicant has been inspecting the top guide hold down assemblies in accordance with BWRVIP-26A even though the BWRVIP's evaluation of lift forces for BWR top guides indicates that the top guide at FitzPatrick will not lift under a postulated faulted event. Thus, a one-cycle deferral of the examination is justified and the inspections during RO17 did not detect any indications of cracking in the top guide rim hold down assemblies.

The LRA credits the Water Chemistry Control-BWR program alone to manage this aging effect.
Please provide the technical justification for concluding that the water chemistry control-BWR AMP alone is adequate to manage cracking of these components with no associated inspection.The feedwater thermal sleeves are entered both inTable 3.1.2-1 (the reactor vessel) and in Table 3.1.2-3 (the reactor coolant system pressure boundary). The thermal sleeves are handled more completely in Table 3.1.2-1 and will be deleted from Table 3.1.2-3. The feedwater thermal sleeve entry in table 3.1.2-1 credits the BWR Feedwater Nozzle Program in addition to Water Chemistry Control for managing cracking.

In this license amendment, the applicant deleted the AMR line items for feedwater (FW) thermal sleeves from Table 3.1.2-3 of the LRA. This leaves the AMR line items for the FW thermal sleeves in LRA Table 3.1.2-1 as the applicable AMR line items.

The further evaluation states that the Periodic Surveillance and Preventive Maintenance Program supplements the Water Chemistry Control-BWR program for components at the waterline in the suppression chamber and for components subject to erosion. Please clarify whether the PSPM program is in addition to the one-time inspection program, or whether it replaces the one-time inspection program for the components addressed by this AMR.The PSPM program replaces the One-timeInspection Program for this line item. The PSPM program is described in Section 3.2.2.2.8 for management of components at the waterline in the suppression chamber that are not completely wetted. A periodic inspection is specified since the Water Chemistry Control-BWR Program alone is not adequate to manage the effects of aging on steel piping and components at the water line in the suppression chamber.The applicant stated that the PeriodicSurveillance and Preventive Maintenance Program replaces the one-time inspection for management of components at the waterline in the suppression chamber that are not continuously wetted. The Periodic Surveillance and Preventive Maintenance Program is credited for these components since a periodic inspection is needed to monitor aging of these components. The project team determined that it includes periodic inspections that are consistent with a one-time inspection and will be effective to verify the effectiveness of the water chemistry program for components at the waterline in the suppression chamber. The project team finds the applicant's response acceptable because a periodic inspection is appropriate for these components since they are intermittently wetted, which could make them more susceptible to degradation.

This is acceptable because it isconsistent with the recommendations in GALL AMP XI.M34, "Buried Piping and Tanks Inspection." See amendment letter No. 5, dated February 01, 2007. This question is resolved.248364AMR line-item 3.2.1-19 addresses wall thinningdue to flow-accelerated corrosion for steel piping, piping components, and piping elements exposed to steam or treated water. The AMR states that the Periodic Surveillance and Preventive Maintenance program provides augmented inspections for flow wall thinning.
Please discuss the augmented inspections performed and why they are not included in the Flow-Accelerated Corrosion AMP.The core spray, HPCI and RCIC piping included inthis line item are administratively controlled in the Flow Accelerated Corrosion program, but are inspected using NDE techniques such as UT in the Periodic Surveillance and Preventive Maintenance program. This is being done because the aging effect for these components is loss of material due to erosion and not loss of material due to flow accelerated corrosion. It would therefore not be appropriate to manage using the Flow Accelerated Corrosion program. Therefore these components are managed by the Periodic Surveillance and Preventive Maintenance program.The applicant stated that augmentedinspections are performed at JAFNPP on selected piping components that are not part of the inspections required by applicant's Generic Letter 89-08 program, which are performed under the GALL AMP XI.M17 Program. These inspections are the same as those performed under the FAC Program, but are included in the Periodic Surveillance and Preventive Maintenance Program for administrative reasons since the aging effect is not FAC. The project team reviewed the applicant'sPeriodic Surveillance and Preventive Maintenance Program and determined that this aging management program includes measurement of wall thickness for the RCIC piping to detect loss of material due to erosion. This is the same activity that would be performed under the FAC program, and acceptance criteria are established in accordance with the FAC Program. Since these inspections are the same as those performed under the FAC Program, the activities are consistent with the recommendations in GALL AMP XI.M17 to manage wall thinning due to flow-accelerated corrosion for steel components exposed to steam or treated water. On this basis, the project team Question and Answer Database Audit and Review Related to the License Renewal Application for James A. Fitzpatrick Nuclear Power plant No.Applicant'sRef. No.Audit QuestionsApplicant's ResponseProject Team's Evaluations 169finds the AMR results for this line itemacceptable.
This question is resolved.249365AMR line-item 3.2.1-24 addresses loss ofpreload due to thermal effects, gasket creep, and self-loosening. The AMR states that this is not applicable since loss of preload is a design-driven effect and not an aging effect requiring management. A discussion of thermal effects is provided. Please provide the following information with regard to this AMR, a) discuss why gasket creep and selfloosening are not aging mechanisms that could lead to loss of preload for steel closure bolting in the ESF systems at JAFNPP, and b) discuss JAFNPP's operating experience with steel closure bolting in the ESF systems.a) Gasket creep and self-loosening aremechanisms that could lead to loss of preload for steel closure bolting, but are not considered aging mechanisms. Operating experience indicates that these mechanisms occur in relatively short order in applications with improper bolted joint design or installation. This is consistent with the EPRI Mechanical Tools (EPRI 1010639) that do not consider loss of preload an aging effect for bolted closures. Gasket creep will normally occur shortly after initial loading, which allows for addressing this effect by installation practices and subsequent maintenance of the joint and is therefore not related to aging. Self-loosening is also not an aging effect but is an event-driven effect that occurs due to improper joint design or installation that doesn't properly consider the potential for this effect. This would also be detected early in component service life and actions would be taken to prevent recurrence.
b) A review of JAFNPP site operating experience over five years was performed. Search results were screened to determine whether the identified condition was related to pressure boundary bolting that may have experienced cracking or loss of preload. The majority of the search results involved event-driven conditions that required no further review. The review found instances of loss of material due to corrosion, loose bolting due to improper maintenance practices, and cracking of Class 1 bolting, but no evidence of cracking or loss of preload for non-Class 1 pressure boundary bolting.AMR line item 3.2.1-24 state "not applicable" in thediscussion section that describes loss of preloadThe applicant stated that this position isconsistent with the EPRI Mechanical Tools report (EPRI 1010639); however, the bolting integrity program is currently used at JAFNPP to monitor these components. The applicant committed to amend the LRA to delete "Not Applicable" from this AMR line item. In its letter dated February 1, 2007, theapplicant amended the LRA to delete "Not Applicable" from this AMR line item. The project team reviewed the applicant's bolting integrity program and determined that it is consistent with the recommendations in GALL AMP XI.M18, and includes activities that will manage loss of preload for these components. On this basis, the staff finds this AMR acceptable. This question is resolved.

The AMR credits the Periodic Surveillance and Preventive Maintenance Program instead of the Open-Cycle Cooling Water System AMP, which is recommended by NUREG-1801. Please discuss the evaluation performed to conclude that the activities in the Periodic Surveillance and Preventive Maintenance AMP are consistent with the activities in the Open-Cycle Cooling Water AMP recommended by NUREG-1801 for the components addressed by this AMR, including the activities performed to manage aging, the sample population inspected, and the inspection locations.AMR line-item 3.2.1-35 addresses componentsincluded in containment isolation penetrations for drains from the drywell floor and equipment sumps.
The internal raw water environment for these components is drainage from containment, which is not the raw lakewater in the Open-Cycle Cooling Water System AMP XI.M20. Therefore, the actions from Generic Letter 89-13 that are described in NUREG-1801 XI.M20 are not appropriate for these items (See Table 3.0-1, page 3.0-9 of the LRA).
For this environment the Periodic Surveillance and Preventive Maintenance Program manages the aging effects in these components. Visual or NDE techniques will be used to detect aging effects on internal surfaces at a specified interval of 5 years.
These techniques will be applied on a representative sample basis to detect degradation prior to loss of intended function. This inspection will be done in the internal piping and valve bodies of containment penetration X-18 and X-19.The project team finds the applicant'sresponse acceptable because the environment for these components is not raw water from the ultimate heat sink and thus, the components are not within the scope of the Open-cycle Cooling Water Program. The project team considers the Periodic Surveillance and Preventive Maintenance Program to be capable of managing these aging effects of the components addressed in AMR line item 3.2.1-35 because the program calls for both periodic visual and non-visual NDE techniques of these containment isolation penetration drain components every 5 years.

This question is resolved.255371Table 3.2.2-1 in the LRA includes a line-item forHeat Exchanger (tubes) in the Residual Heat Removal Systems constructed of stainless steel and exposed to treated water >140F. The aging effect identified is loss of material-wear and the AMP credited is Service Water Integrity (AMP B.1.26). Please clarify why AMP B.1.26, which addresses components exposed to service water, is credited for this AMR instead of a water chemistry AMP.Wear is a mechanism caused by relative motionbetween adjacent components. Water chemistry cannot prevent the conditions that cause wear.
These heat exchangers are included in the Service Water Integrity Program since they are cooled by the service water system. Although loss of material due to wear occurs on the external surface of the tubing (which is exposed to treated water) this aging effect will be managed by eddy current testing of the tubes in the Service Water Integrity Program.The project team finds the applicant'sresponse acceptable because wear is not a mechanism that deteriorates metallic materials as a result of a chemical effect.
Instead, wear is a mechanism that results in loss of material as a result of metal abrasion (i.e., metal to metal surface contact). Thus, a chemical monitoring program will not include the type of inspection-based techniques that are capable of detecting aging as a result of wear. Since the heat exchangers are Question and Answer Database Audit and Review Related to the License Renewal Application for James A. Fitzpatrick Nuclear Power plant No.Applicant'sRef. No.Audit QuestionsApplicant's ResponseProject Team's Evaluations 173cooled by the service water system, theService Water Integrity Program is adequate to manage the aging effect because the program will use a volumetric inspection technique (i.e, eddy current testing) to monitor whether loss of material due to wear is occuring in these tubes. This question is resolved.256372The further evaluation presented in Section3.2.2.2.7 of the LRA addresses loss of material due to general corrosion and fouling for steel drywell and suppression chamber spray system nozzle and flow orifice internal surfaces exposed to air-indoor uncontrolled (internal).
The further evaluation states that at JAFNPP the spray nozzles are copper alloy and are not subject to loss of material due to general corrosion in an indoor air environment. Industry operating experience has shown that corrosion products from piping upstream of these nozzles can detach and cause blockage of the nozzles.
Please provide the following information related to this further evaluation: a) discuss the testing performed to ensure the drywell and suppression chamber spray nozzles are unobstructed, including the nature and frequency of this testing; b) discuss the results of previous tests performed, including whether any blockage of nozzles was observed, the cause of the blockage, and the corrective actions taken; and c) discuss how nozzle blockage due to corrosion products from upstream piping will be managed at JAFNPP.Surveillance testing to ensure the drywell andsuppression chamber spray nozzles are unobstructed is completed at JAFNPP by aligning service air to each of the spray headers in the drywell and suppression chamber spray system and verifying air flow from each spray nozzle. This surveillance test is performed once every 10 years in accordance with the JAFNPP Inservice Inspection Program. The testing detected some cases of nozzle blockage. The amount of blockage was below the acceptance criteria for the surveillance. The blockage was removed after testing. Continued surveillance testing will ensure that the active function of flow control is assured.The project team finds the applicant'sresponse acceptable because the surveillance testing is an adequate performance monitoring program that is capable of verifying whether or not adequate spray system nozzle flow capability is being maintained during the period of extended operation or whether implementation of corrective actions is necessary should blockage of the system be verified as a result fo the surveillance test. This is consistent with NRC Branch Technical Position RLSB in (NUREG-1800, Revision 1, on how performance monitoring programs may be used to ensure aging management during the period of extended operation .

The AMR states that there are no aging mechanisms or effects for these material/environment combinations, which is consistent with NUREG-1801. The LRA also states that the only components to which this NUREG-1801 line-item applies are in the auxiliary systems. Please discuss the JAFNPP plant-specific operating experience with components in the auxiliary systems containing these material/environment combinations.the auxiliary systems containing this material andenvironment combination is consistent with the industry experience of no aging effects reflected in NUREG-1801 and the Mechanical Tools [Non-Class 1 Mechanical Implementation Guideline and Mechanical Tools, Revision 4, EPRI, Palo Alto, CA:

This question is resolved.258374The further evaluation presented in Section3.3.2.2.3, Item 3, of the LRA addresses cracking due to SCC in stainless steel diesel engine exhaust piping exposed to diesel exhaust. The further evaluation states that at JAFNPP, the stainless steel exhaust components are oriented vertically, which precludes pooling of water. Therefore, cracking due to SCC is not an aging effect requiring management for the stainless steel diesel engine exhaust piping. Please discuss the JAFNPP plant-specific operating experience with stainless steel diesel engine exhaust piping, and the results of the most recent inspection performed on these components. As part of the response, please address the reason for not performing a one-time inspection of these components to confirm that cracking is not occurring.Inspection of the exhaust system components isincluded in the Periodic Surveillance and Preventive Maintenance program as discussed in JAF-RPT-05-LRD-02 Attachment 3.
Conservatively, these components will be inspected for loss of material once every five years during the period of extended operation. Because there is no potential for the accumulation of water, there is no moisture available for the concentration of contaminants such as chlorides which would provide an environment conducive for the initiation of cracking. This evaluation is in accordance with the EPRI Mechanical Tools for the determination of aging effects. Further evaluation section 3.3.2.2.3 will be revised to state that the PSPM program will verify the absence of cracking in the stainless steel exhaust components.This requires an amendment to the LRA.The project team finds the applicant'sresponse acceptable because the applicant amended the LRA to state that the PSPM program will verify the absence of cracking in the stainless steel exhaust components. See amendment letter No. 5, dated February 01, 2007. This question is resolved.259375The further evaluation presented in Section3.3.2.2.6 of the LRA addresses reduction of neutron-absorbing capacity for Boral spent fuel storage racks.

Please provide additional details on the JAFNPP plant-specific operating experience with Boral coupons, and the results of the coupon tests performed in 2005 that support the conclusion that an aging management program is not required.* the pitting was attributed to residual carbon steelchips left on the surface of the Boral during assembly of the capsules.
- the blisters were attributed to hydrogen formed by reaction between the pool water and internal surfaces of the aluminum.These conditions of appearance did not affect theintended function of the boral material. The areal densities determined by neutron attenuation measurements and verified by wet chemical analysis were, in every case, in excess of the minimum as-fabricated values which confirms that reduction in neutron absorption capacity is not an aging effect requiring management. Loss of material and cracking are managed by the Water Chemistry Control program. This testing is documented in CR-JAF-2005-00631, which was available for review on site.use of non-destructive testing is consistentwith the guidance presented in Section A.1.2.1 of NUREG 1800, which specifies that the determination of applicable aging effects should be based on degradations that could cause structure and component degradation. The Water Chemistry Control - BWR Program includes activities that are consistent with recommendations in NUREG-1801, and is adequate to manage loss of material and cracking for Boral spent fuel storage racks exposed toa treated water environment. The staff concurs with the applicants conclusion that reduction of neutron-absorbing capacity is insignificant and requires no aging management. This question is resolved.260376The further evaluation presented in Section3.3.2.2.8 of the LRA addresses loss of material due to general, pitting, crevice and MIC for carbon steel (with or without coating or wrapping) piping and components buried in soil in the auxiliary systems at JAFNPP. The further evaluation states that an inspection of buried components will be performed within ten years of entering the period of extended operation.
Please confirm that an inspection will also be performed during the ten-year period immediately prior to entering the period of extended operation.See response to AMP Audit Question No.52The project team finds the applicant'sresponse acceptable because the applicant amended the LRA in a letter dated February 01, 2007, to state that if an opportunistic inspection did not occur, a focused inspection will be performed prior to the period of extended operation in accordance with GALL Report recommendations. This question is resolved since the applicant is consistent with the guidance in GALL AMP B.1.1.261377AMR line-item 3.3.1-45 addresses loss ofpreload due to thermal effects, gasket creep, and self-loosening. The AMR states that this is not applicable since loss of preload is a design-driven effect and not an aging effect requiring management. A discussion of thermal effects is provided. Please provide the following information with regard to this AMR, a) please provide a discussion of why gasket creep and self-loosening are not aging mechanisms thata) This is consistent with the EPRI MechanicalTools (EPRI 1010639) that do not consider loss of preload to be an aging effect for bolted closures.
Gasket creep will normally occur in 10 to 20 minutes after initial loading, which allows this effect to be addressed by installation practices and subsequent maintenance of the joint and is therefore not related to aging but is event driven.
Self-loosening is also not an aging effect but is an event driven effect that occurs due to improper jointThe project team finds the applicant'sresponse acceptable because the applicant amended the LRA to credit Bolting Integrity Program to manage the aging effect of loss of preload in these bolted connections. See amendment letter No. 5, dated February 01, 2007. This question is resolved.

This would also be detected early in component service life and actions would be taken to prevent recurrence.
b) A review of JAFNPP site operating experience over five years was performed. Search results were screened to determine whether the identified condition was related to pressure boundary bolting that may have experienced cracking or loss of preload. The majority of the search results involved event-driven conditions that required no further review. The review found instances of loss of material due to corrosion, loose bolting due to improper maintenance practices, and cracking of Class 1 bolting, but no evidence of cracking or loss of preload for non-Class 1 pressure boundary bolting.AMR line item 3.3.1-45 states "not applicable" inthe discussion section that describes loss of preload due to thermal effects, gasket creep, and self-loosening. The term "not applicable" will be removed from the discussion section of these line items, since these components are inspected under the Bolting Integrity Program.
This requires an amendment to the LRA.262378AMR line-item 3.3.1-62 addresses loss ofmaterial due to pitting and crevice corrosion for aluminum piping, piping components, and piping elements exposed to raw water. The LRA credits the one-time inspection program to manage this aging effect; however, NUREG-1801 recommends the Fire Protection program.
Please discuss the justification for using the one-time inspection program instead of the Fire Protection program to manage this aging effect.As identified in line item 3.3.1-62, the onlycomponents to which this NUREG-1801 line item applies are included in scope under criterion 10 CFR 54.4(a)(2) and are listed in the series 3.3.2-14-xx tables. As indicated in the tables, the aluminum component addressed by line item 3.3.1-62 is in the radwaste system. As such, the fire protection program is not appropriate to manage the effects of aging. Aluminum is a corrosion resistant material that is not expected to experience significant loss of material in this environment. As described in LRA Appendix B, the One Time Inspection Program will confirm that loss of material is not occurring or is so insignificant that an aging management program is not warranted.
Therefore the one-time inspection program is appropriate for managing this aging effect.The project team finds the applicant'sresponse acceptable because the applicant clarified that the aluminum component addressed by line item 3.3.1-62 is in the radwaste system. Therefore, the fire protection program is not appropriate to manage the effects of aging on this component. In addition, based on industry research and operating experience, the project team recognizes that aluminum is a corrosion resistant material that is not expected to experience significant loss of material in this environment. Therefore, One-Time Inspection Program is appropriate for managing this aging effect. This question is resolved.

The LRA states that the Periodic Surveillance and Preventive Maintenance and One-Time Inspection programs are used to manage this aging effect.
NUREG-1801 recommends the Inspection of Internal Surfaces in Miscellaneous Piping and Ducting Components program. While this Table 1 line-item indicates that both AMPs are used together to manage this aging effect, a review of the Table 2 AMR line-items shows that only the OTI program or the PSPM program is credited; not both. Please clarify this apparent discrepancy between Table 1 line item 3.3.1-71 and the corresponding Table 2 line items in terms of which AMPs are credited. Also, if the OTI or PSPM program will be used alone to manage this aging effect, please discuss the evaluation that was performed to determine that the activities in each of these programs are consistent with the Inspection of Internal Surfaces in Miscellaneous Piping and Ducting Components program recommended in NUREG-1801.As described in LRA Section 3.0, the "Discussion"column in Table 1 provides a discussion of how the line item compares to the corresponding line item in NUREG-1801, Volume 1. In the case of line item 3.3.1-71, either of two programs which are different than the one listed in the corresponding GALL line item may be used to manage the specified aging effects wherever this material environment combination appears in the Table 2 entries. The use of "and" is not meant to imply that both programs are required to manage the aging effects.
Selection of either the One-Time Inspection or Periodic Surveillance and Preventive Maintenance (PSPM) program is based on the environment, and the type and configuration of components described in the Table 2 entries.The One-Time Inspection program is used insituations where the goal is to confirm that loss of material is not occurring or is so insignificant that an aging management program is not warranted.
The PSPM program is used in situations where the aging effect is likely and therefore requires aging management. The line items that compare to GALL line item 3.3.1-71 in Table 3.3.2-14-41 and credit the One-Time Inspection program are in error.
These line items should have credited the Periodic Surveillance and Preventive Maintenance program.
This change requires an amendment to the LRA.NUREG-1801 states that XI.M38 "Inspection ofInternal Surfaces in Miscellaneous Piping and Ducting Components" is used for components that are not covered by other aging management programs. This GALL program uses visual inspections to manage aging effects. The Periodic Surveillance and Preventive Maintenance (PSPM)
Program described in Appendix B also uses visual inspections to manage loss of material and is consistent with the attributes described for the program in NUREG-1801 XI.M38.The project team finds the applicant'sresponse acceptable because the applicant amended the LRA to credit PSPM program to manage the aging effect. See amendment letter No. 5, dated February 01, 2007. The program attributes and the visualinspection criteria in the PSPM to manage loss of material in these components are consistent with the program attributes in GALL AMP XI.M38, "Inspection of Internal Surfaces in Miscellaneous Piping and Ducting Components" and are acceptable

The LRA states that these components are evaluated as structural components in Section 3.5, and that the Periodic Surveillance and Preventive Maintenance and Structures Monitoring programs are credited to manage these aging effects. However, NUREG-1801 recommends the Inspection of Overhead Heavy Load and Light Load (Related toRefueling) Handling Systems program.

The AMR identified appropriate AMPs to manage aging effects. In this case, reactor building steel crane structural girders used in load handling are inspected under the Periodic Surveillance and Preventive Maintenance Program (PSPM) identified in Section B.1.22 of the application.
Turbine building complex and yard structures crane rails and girders are inspected under the StructuresMonitoring Program as identified in Section B.1.27.
The Structures Monitoring Program will be enhanced, as identified in Section B.1.27, to address crane rails and girders.These programs when enhanced will include visualinspections of the crane rails and girders which is consistent with XI.M23 for managing loss of material.The project team finds the applicant'sresponse acceptable because the applicant identified appropriate programs to manage the aging effect of crane components in Section 3.5 of the LRA.
This question is resolved.265381AMR line item 3.3.1-76 addresses loss ofmaterial for steel piping, piping components, and piping elements exposed to raw water. The LRA states that for some of these components, the Periodic Surveillance and Preventive Maintenance program is credited to manage this aging effect. However, NUREG-1801 recommends the Open Cycle Cooling Water System program. Please discuss the evaluation that was performed to determine that the activities in the PSPM are consistent with the Open Cycle Cooling Water System program.Line Item 3.3.1-76 specifies the PeriodicSurveillance and Preventive Maintenance (PSPM)
Program instead of XI.M20, Open-Cycle Cooling Water System Program, in line items where the environment of raw water is used to identify untreated water that is not part of the service water system. The affected components are not part of the open cycle cooling water system, therefore, the actions from the Open Cycle Cooling Water System Program described in NUREG-1801 XI.M20 are not appropriate for these items.The five year PSPM frequency is acceptablebecause (1) Aging effects for carbon steel, even in raw water, are not fast acting; (2) PSPM inspection activities are preformed on (a)(2) systems that have been in service for the life of the plant without required inspections per the JAFNPP corrective action program; and (3)The consequences of failure due to loss of material are low. SRPThe project team finds the applicant'sresponse acceptable because the environment for these components is not raw water from the ultimate heat sink and thus, the components are not within the scope of the Open-cycle Cooling Water Program. The project team considers the Periodic Surveillance and Preventive Maintenance Program to be capable of managing these aging effects of the components addressed in AMR line item 3.2.1-76 because the program calls for both periodic visual and non-visual NDE techniques of these auxiliary system drain line components every 5 years. This should be an adequate inspection frequency given that these are drain line components. This question is resolved.

Probabilistic arguments may be used to assist in developing an approach for aging management adequacy.
However, use of probabilistic arguments alone is not an acceptable basis for concluding that, for those structures and components subject to an AMR, the effects of aging will be adequately managed in the period of extended operation.
Thus, risk significance may be considered in developing the details of an aging management program for the structure or component for license renewal, but may not be used to conclude that no aging management program is necessary for license renewal." Therefore, periodic inspections of non-safety related systems conducted on a five year frequency or less is acceptable.266382AMR line item 3.3.1-77 addresses loss ofmaterial for steel heat exchanger components exposed to raw water.

The LRA states that for some components, the Periodic Surveillance and Preventive Maintenance and One-Time Inspection programs are used to manage this aging effect. NUREG-1801 recommends the Open-Cycle Cooling Water System program. While these Table 1 line items indicate that both AMPs are used together to manage this aging effect, a review of the Table 2 AMR line items shows that only the OTI program or the PSPM program is credited; not both. Please clarify this apparent discrepancy between Table 1 line items 3.3.1-79 and 3.3.1-81 and their corresponding Table 2 line items in terms of which AMPs are credited. Also, if the OTI or PSPM program will be used alone to manage this aging effect, please explain why the PSPM or OTI programs are credited.The Periodic Surveillance and PreventiveMaintenance (PSPM) Program and the One-Time Inspection (OTI) Program are not intended to be combined for the management of aging effects.
The use of the word "and" was intended to identify that these two programs are credited individually in specific line items to manage aging effects. The PSPM or OTI programs are specified in line items where the environment of raw water is used to identify untreated water further defined as drain water, radwaste water, ventilation system drain water, potable water, and chemical treatment water. Since Service Water Integrity is not applicable for these raw water environments, PSPM or OTI appropriately manage aging effects for these environments. The PSPM program is specified where the component is primarily wetted and the material-environment combination is more susceptible to aging effects. The OTI program is specified for stainless steel or copper alloy components that are not susceptible to significant aging effects. The project team reviewed the LRA andbases documents and determined that the components addressed by the AMR line items that credit the Periodic Surveillance and Preventive Maintenance Program are in the radwaste and plant drains system, and the service water system. The project team also reviewed the applicant's Periodic Surveillance and Preventive Maintenance Program and determined that this program includes inspections of components in the radwaste and drains system, and the service water system, using visual and other proven NDE techniques that are appropriate for managing loss of material. The inspections are performed every 10 years for stainless steel drain tanks, and every five years for stainless steel components used in chemical treatment in the service water system. Any significant loss of material detected will be evaluated to determine if corrective actions are required. The project team finds these activities adequate to manage loss of material for these components. On this basis, the project team finds that the AMR results addressed by this line item that credit the Periodic Surveillance and Preventive Maintenance Program are acceptable.The project team also reviewed the LRAand bases documents and determined that the components addressed by this AMR line items that credit the One-Time Inspection Program are in the raw water treatment system, the plumbing, sanitary and lab system, and the city water system.

Any significant loss of material detected will be evaluated to determine if corrective actions, including expansion of the inspection sample size, are required. The project team finds these activities acceptable to manage loss of material for these components since, based on industry research and operating experience, this material/environment combination is not susceptible to corrosion. In addition, the components exposed to drains are not continuously wetted, which further reduces their susceptibility to corrosion. On this basis, the project team finds that AMR results addressed by this line item that credit the One-Time Inspection Program are acceptable.This question is resolved. 268384AMR line item 3.3.1-83 addresses reduction ofheat transfer due to fouling for copper alloy heat exchanger tubes exposed to raw water.

The AMR states that there are no aging mechanisms or effects for these material/environment combinations, which is consistent with NUREG-1801. Please discuss the JAFNPP plant-specific operating experience with components in the auxiliary systems containing these material/environment combinations.A review of five years of JAFNPP operatingexperience did not identify aging effects for components in the auxiliary systems with these material and environment combinations. The operating experience review is documented in JAF-RPT-05-LRD05, JAFNPP License Renewal Operating Experience Review Report, which was available for onsite review.JAFNPP operating experience with these materialand environment combinations is consistent with the industry experience of no aging effects reflected in NUREG-1801 and the Mechanical Tools [Non-Class 1 Mechanical Implementation Guideline and Mechanical Tools, Revision 4, EPRI, Palo Alto, CA: 1010639].The project team finds the applicant'sresponse acceptable because this material/ environment combination has no aging effect and it is consistent with GALL Report. This question is resolved.274390The further evaluation presented in Section3.3.2.2.5, Item 1, of the LRA addresses cracking and change in material properties due to elastomer degradation in elastomer flexible connections of auxiliary systems and othersystems exposed to air-indoor. The further evaluation states that these aging effects are managed by the Periodic Surveillance and Preventive Maintenance Program.
Please provide the technical justification for concluding that the PSPM program will provide reasonable assurance that the effects of aging will not compromise any intended function during the period of extended operation for these components. The response should address a) how an appropriate sample size will be assured, b) how the selection of inspection locations that include the most susceptible components will be assured, c) the criteria that will be used to determine if corrective actions are required based on inspection results, andThe PSPM program as described in LRA SectionB.1.22 is a program that requires periodic inspection of a sample of elastomers in each system crediting this program. Because the program requires periodic inspections, the detection of aging effects will be ensured. The inspection frequencies and acceptance criteria for these components are described in Attachment 3 to JAF-RPT-05-LRD02. Because these components are elastomer materials exposed to the same environment of indoor air there are no locations that provide an environment that would be significantly more susceptible to aging effects.
These inspections are new such that the details on the sample size are not available. However, the sample size will be selected from all elastomer components that credit this program, it will consider operating experience in the selection of the sample size and it will be a statistically appropriate sample size.

The AMR states that there are no aging mechanisms or effects for these material/environment combinations. NUREG-1801 Volume 2 item VII.F1-7 is cited, which recommends a plant-specific aging management program. A plant specific note (309) in the LRA states that changes of material properties and cracking in elastomers are results of exposure to ultra-violet light or elevated temperatures (>95oF). The note further states that the interior surfaces of these components are not exposed to ultra-violet light and are part of the air intake that is not exposed to elevated temperatures. However, the staff notes that there are other elastomer duct flexible connections exposed to similar environments in other systems that have been identified as being susceptible to aging and requiring aging management, for example in the HVAC systems (Table 3.3.2-7). Please clarify why the elastomer duct flexible connections addressed in this AMR are not susceptible to aging while other elastomer duct flexible connections in other systems are identified as requiring aging management.This particular line item is in reference to a specificcomponent (the diesel intake air flexible connection) and is only applicable to the interior surface of the component. The reason why there are no aging effects for the interior surface is explained by note 309. In accordance with the EPRI Structural Tools for the evaluation of aging effects for elastomer materials, if an elastomer is not exposed to temperatures above 95°F or ultraviolet light the material will not experience aging effects. The exterior surface of this same component (duct flexible connection exposed to indoor air (ext)) is identified in Table 3.3.2.3 and includes the aging effects of cracking and change in material properties since it is exposed to ultraviolet light. It will be managed by the PSPM program visual inspections. This line item is only meant to identify that there will be no aging on the inside of the expansion joint. However, the outside is susceptible to aging and will be inspected.The project team finds the applicant'sresponse acceptable because the applicant clarified that the line item is in reference to a specific component (the diesel intake air flexible connection) and is only applicable to the interior surface of the component. In addition, the applicant clarified that the elastomer material will not experience aging effects since it is not exposed to temperatures above 95°F or ultraviolet light.

These heat exchangers are included in the Service Water Integrity Program since they are cooled by the service water system and are part of GL 89-13 commitments. Although loss of material due to wear occurs on the external surface of the tubing (which is exposed to treated water) this aging effect will be managed by eddy current testing of the tubes in the Service Water Integrity Program.The project team finds the applicant'sresponse acceptable because the Service Water Integrity Program which includes GL 89-13 commitments and eddy current testing is adequate to detect loss of material due to wear on the copper alloy tubes. This question is resolved.292408Table 3.3.2-12 includes AMR line items toaddress fiberglass piping and tanks exposed to air-indoor, raw water, and soil in the Radwaste and Plant Drains systems.

The power is supplied to plant 4.16kV emergency buses by back feeding from the 345kV system via main transformer, isolated phase bus duct, and the normal station transformer. Back feeding is identified as a qualified alternate source of AC power to 4.16kV safety buses and therefore, should be included in the scope of license renewal. Provide a technical justification why the alternate AC source to 4.16kV safety buses from the 345kV system does not need an AMP/The three sources of normal AC power for JAF arethe normal, reserve, and emergency sources. The normal source is the Normal Service Station Transformer (NSST) 71T-4. The reserve source is the Reserve Service Station Transformers (RSST) 71T-2 and 71T-3. The emergency source is the Emergency Diesel Generators.In Section 8.3 of the JAF UFSAR, the 115KVsystem has the safety objective to provide a supply of offsite power for the engineered safeguard loads.
The 115KV system has the power generation objective to provide two sources of offsite AC power to the Plant Service AC Power DistributionThe project team finds the applicant'sresponse acceptable because back feeding from 345kV is not credited for SBO offsite recovery. The two 115kV buses which are energized from independent 115kV transmission lines provide power to the 4.16kV safety buses during startup, shutdown, and SBO recovery. This design is consistent with 10 CFR 50, Appendix A, General Design Criteriion 17.

The 115KV bus at JAF is energized from two 115KV transmission lines as shown in SAR Figure 8.3-2. This provides the GDC- 17 criteria for the Reserve Service Station Transformers. Section 8.11 of the JAF UFSAR, addresses Station Blackout (SBO). Station Blackout (SBO) is defined in 10 CFR 50.2 as a complete loss of alternating current (AC) electric power to essential and non-essential switchgear buses. Offsite power is assumed to be lost concurrently with a main turbine trip and unavailability of the on-site emergency AC power system. Station Blackout does not include loss of AC power to buses fed by the station batteries through inverters and does not assume a concurrent single failure or design basis accident.Section 8.2.1 of the JAF UFSAR, states that "Analternate source of AC power, from the 345KV system, is available to provide power to plant auxiliaries during plant shutdown. The power is supplied to plant 4.16KV buses by back feeding from the 345KV system via main transformers, isolated phase bus duct, and the normal station service transformer. The main generator is isolated by removing the isolated phase bus duct disconnect links". This alternate source is only used during outages for maintenance on the Reserve Service Station Transformer. This source of offsite AC power is not credited for recovery from Station Blackout.
The two sources of offsite AC power is the two independent 115KV lines that feed the RSST transformers. There is a cross feed circuit that can be closed to provide power to both of the 4.16KV safety buses in the plant in the case of loss of one 115KV line. This cross-tie can be closed in less than ten minutes when needed.

This question is resolved.322463Provide a listing of the Medium Voltage cablesinstalled and how they were screened for GALL XI.E3.The list of Medium Voltage cables installed for JAFwere provided to NRC.A summary of cable screening is listed below.
The 4KV cables for RHR Service Water are locatedwithin a building and run in conduit that is surrounded by concrete. This conduit run is not underground and not susceptible to moisture.The Core Spray Cables and RHR Cables are EQand managed by the EQ Program.There are some installed spare 4KV cables that arenot connected and not energized.The EDG cables are in conduit in a building andare not in duct bank underground. The EDG cables are not energized >25% of the time.The 4KV Neutral Grounding Resistor Cabling isinstalled on the RSST transformers and is tied to plant ground. These cables are low voltage and not susceptible to moisture and water treeing.Therefore, JAF does not have any 4KV cables thatwould require a GALL XI.E3 program. The 4KV cables that are in scope of license renewal are managed by the GALL XI.E1 program.The project team finds the applicant'sresponse acceptable because JAFNPP does not have any non-EQ inaccessible medium-voltage cables in scope of GALL XI.E3. To be included in GALL Program XI.E3, cables within scope of license renewal have to be non-EQ, medium-voltage (2kV to 35kV), and are subjected to significant moisture (installed in duct banks, cable trend underground) and significant voltage (energized more than 25% of the time).

CR-JAF-1993-00502 was written to evaluate a leak in the H2 supply buried piping between the storage facility and the turbine building. The root cause for this CR recommended replacement of this section of piping, because of poor application of protective coatings. Therefore, this pipe leak was the result of a manufacturing issue not aging.During a period from the mid-1990s to present,several fire protection system buried valves were excavated through the work order process. None of the excavated valves showed evidence of corrosion; therefore, no CRs were written.The project team finds the applicant'sresponse acceptable because the operating experience demonstrates that JAFNPP is not experiencing any aging mechanisms that are not bounded by industry operating experience. This question is resolved. 332473For AMP B.1.21, One-Time Inspection, pleaseexplain the inspection sample size for each inspection and state how it will be expanded if degradation is detected.The sample size is based on Chapter 4 of EPRIdocument 107514, Age Related Degradation Inspection Method and Demonstration, which outlines a method to determine the number of inspections required for 90% confidence that 90%
of the population does not experience degradation (90/90). Components with the same material-environment combinations at other facilities may be included in the sample.The program provides for increasing inspectionsample size and locations in the event that aging effects are detected. Unacceptable inspection findings are evaluated in accordance with the JAFNPP corrective action process to determine the need for subsequent (including periodic) inspections and for monitoring and trending the results.The sample size is based onEPRI 107514,"Age-Related Degradation Inspection Method and Demonstration,"
Chapter 4. For verification of the effectiveness of the water chemistry programs, the scope will include a representative sample of the components crediting the Water Chemistry Program.
Since operating experience identified a history of low oxygen and high iron content in the reactor building closed loop cooling (RBCLC) system, the sample population will specifically include components in this system.

This question is resolved. 333474For AMP B.1.21, One-Time Inspection, pleaseexplain how the specific inspection technique and location will be determined.Inspection techniques will be selected fromestablished NDE techniques, including visual, ultrasonic, and surface techniques that are performed by qualified personnel following procedures consistent with the ASME Code and 10 CFR Part 50, Appendix B.The inspection and test techniques will have ademonstrated history of effectiveness in detecting the aging effect of concern. Determination of inspection locations will be based on identification of low flow/stagnant areas, drains, and low points for system components managed by the program.
These components are considered the most susceptible to aging effects.The parameters monitored include wallthickness, fouling, and the extent of cracking. Reduction of fracture toughness is also a parameter to be monitored by inspection of specific CASS components for the extent of cracking. Inspection techniques include visual examination, surface techniques, UT testing, and radiography.The project team determined that theparameters to be monitored are consistent with the aging effects which the LRA credits this program. The inspection techniques are proven methods for detecting loss of wall thickness, fouling, and the extent of cracking, common in the industry, and, therefore, acceptable for the purposes of this AMP.Determination of inspection locations willbe based on identification of low flow/stagnant areas, drains, and low points for system components managed by the program.

This question is resolved. 339482AMR line-item 3.2.1-18 addresses cracking dueto SCC and IGSCC for stainless steel piping, piping components, and piping elements exposed to treated water >60C (>140F). The AMR credits the Water Chemistry-BWR and One-Time Inspection programs instead of the Water Chemistry and BWR Stress Corrosion Cracking programs, which arommended by NUREG-1801. Please explain a single inspection under the one-time inspection program is adequate to replace the periodic inspections included in the BWR SCC program for the AMRs associated with this line item since these are Class 1 pressure boundary components.BWR SCC program is applicable to all BWR pipingand piping welds made of austenitic SS and nickel alloy that is 4 in. or larger in nominal diameter and contains reactor coolant at a temperature above 93°C (200°F) during power operation, regardless of code classification. The piping components included in section 3.2 with temperatures above 200 °F for this line item are less than 4" NPS and are outside the reactor coolant system (RCS) pressure boundary. They are, therefore, outside the scope of the BWR SCC program. As a result the Water Chemistry Control - BWR program is used.
As stated in LRA Section B.1.29.2, the Water Chemistry Control - BWR Program is consistent with the program described in NUREG-1801,Section XI.M2, "Water Chemistry." The One-Time Inspection Program, described in LRA Section B.1.21 includes inspections to verify the effectiveness of the water chemistry control aging management programs (Water Chemistry Control

No JAFNPP calculation or analysis related to cumulative fatigue damage for steel cranes met the definition of TLAA in 10 CFR 54.3. Steel cranes are evaluated as structural components in Section 3.5 of the JAFNPP LRA.The license renewal rule, in 10 CFR 54.3, defines aTLAA as a licensee calculation or analysis that, among other things, involves time-limited assumptions defined by the current operating term.The estimated JAFNPP crane cycles in 40 yearsare 5000 cycles (Section 2.7.1 of LRPD03). TheThe project team finds the applicant'sresponse to be acceptable because: (1) the applicant has clarified that there is no fatigue evaluation for the reactor building cranes, and (2) the applicant has clarified that, while the scope of documents for the cranes do not include applicable TLAAs, the number of lift cycles for the cranes through 60-years of operations is projected to be less the number of lift cycles allowed for in CMAA-70. This question is resolved.

If the 5000 cycles is multiplied by 1.5 to project the number of cycles to 60 years, the resulting 7500 cycles is still well below the CMAA-70 Class A cycle limit.342485Section 4.3.3 of LRA provides the TLAA onenvironmentally-impacted metal fatigue of ASME Class 1 components. The TLAA discussion and evaluation in LRA does not include any environmentally impacted CUF value results for the RHR Class 1 piping or the FW line Class 1 piping at JAFNPP. These are among the locations identified, as a minimum, in NUREG/CR-6260 for environmental CUF evaluations. Discuss the activities and/or usage factor calculations that Entergy will conduct, if any, to ensure that environmentally impacted fatigue of the RHR Class 1 piping and FW line Class 1 piping will be managed in accordance with the acceptance criterion in 10 CFR 54.21(c)(1)(iii) or analyzed and projected for the PEO in accordance with 10 CFR 54.21(c)(1)(ii).
In addition, the staff requests that Commitment No.20 on the JAFNPP LRA be amended to be consistent the wording proposed by Entergy Nuclear Operations, Inc. for Commitment No.31 of the LRA for the Pilgrim Nuclear Power Station.To satisfy LRA Commitment 20, JAFNPP willperform a fatigue analysis, i.e., calculate a CUF, for the RHR and FW piping and then adjust the CUF for environmentally assisted fatigue.Commitment 20 is revised to match the wordingproposed for Commitment 31 for PNPS license renewal. The revised wording for Commitment 20 is included in the response to Question 317.The project team finds the applicant'sresponse to be acceptable because the applicant amended the LRA in amendment letter No. 9, dated April 06, 2007, and placed Commitment No. 20 on the LRA to address environmentally-assisted fatigue of the reactor coolant pressure boundary components.
Commitment No. 20 includes a provision to perform new enviromentally-assisted CUF calculations for the Class 1 portions of the residual heat removal and feedwater piping. This question is resolved.343487At the time Entergy performed its revisedenvironmentally-assisted fatigue analysis, Entergy used hydrogen water chemistry (HWC) implementation to establish the oxygen concentrations (in ppm) used in its Fen adjustment factor calculations. Clarify whether Entergy factored in the oxygen concentrations derived from implementation of normal water chemistry (NWC) in the Fen calculations for those operational periods when NWC was being implemented instead of HWC.JAFNPP instituted hydrogen water chemistry(HWC) in August of 1988. Entergy will re-calculate the Fen values accounting for normal water chemistry (NWC) oxygen concentrations (150 -
200 ppb) and apply the revised Fen to the appropriate CUF values in LRA Table 4.3-3. The results of the revised calculation will be submitted as a change to LRA Table 4.3-3. This requires an LRA amendment. The project team finds the applicant'sresponse to be acceptable because the applicant amended the LRA in amendment letter No. 9, dated April 06, 2007, and placed Commitment No. 20 on the LRA to address environmentally-assisted fatigue of the reactor coolant pressure boundary components.
Commitment No. 20 includes the need to use the oxygen concentrations associated with normal water chemistry and concentrations associated with hydrogen water chemistry in the calculations of Fen.

Question and Answer Database Audit and Review Related to the License Renewal Application for James A. Fitzpatrick Nuclear Power plant No.Applicant'sRef. No.Audit QuestionsApplicant's ResponseProject Team's Evaluations 217344488In Table 8 of JAFNPP Document No. EAS-149-1286, dated January 1987, the fatigue evaluation for the reactor pressure vessel (RPV) closure region bolts calculated the Salt value according to the following equation:
Salt = Sp/2 The value of Sn was not provided. When Sp =
488 ksi, Sn is quite significant and Ke in normally higher than 1.0. Please provide the Sn value for the first load set and describe how it was calculated. Justify that Ke = 1.0.. This question is also applicable to the first load set combination in Table 3-1 of JAFNPP Report SIR-02-045, Revision 1.The Ke factor is not applicable based on thefollowing explanation.The design of the vessel bolts are based on 1965ASME code section III paragraph N-416.A. Paragraph N-416-1 (attached) requires that: 1)The maximum value of service stress, averaged across the bolt cross section and neglecting stress concentrations, shall not exceed two times the stress values of Table N-422; 2) The maximum value of service stress at the periphery of the bolt cross section (resulting from direct tension plus bending) and neglecting stress concentrations shall not exceed three times the stress values of Table N-422. Original design calculation page A-114 (attached) shows that both of these limits are met.B. Paragraph N-416.2 b(1) requires that the peakstresses be calculated using a stress intensification factor of 4.0 (specified in paragraph N-416.4).
Original design calculation page A-107 shows that a stress concentration factor of 4.0 was used to calculate peak stresses.C. Paragraph N-416.2 b(2) states that Salt is equalto one-half of the stress range (max peak stress minus min peak stress). Original design calculation page A-115 shows that Salt were calculated using this method required by the code.
ASME code in section N-416 does not require an additional correction factor to Salt (the Ke factor stated above). The peak alternating stresses already contain a factor of 4.0 due to stress concentration. Since the stresses in calculation EAS-149-1286 (DRF B13-01391) [Ref 3] were obtained from the original vessel calculations [Ref 1], then the methodology used in the original calculations apply to this calculation also.

Fitzpatrick Nuclear Power Plant, January, 1987.345489Table 2 of Minor Change Calculation No. DRN-03-00749 to CalculationNo. SIR-02-045, Revision 1, provides a value of0.852 for the original 40-year CUF and a value of 0.0114 for the 60-year CUF value for the CRD nozzle housing/stub tube junction. This is a factor of 112 difference between the CUF values. Provide your technical basis for the difference in the CUF values.The difference in the CUF values is attributed to:1. The original calculations [1] were performed by very conservative hand computations. These calculations computed the CUF to be 0.780.
Subsequently, this CUF value was revised to account for the Power Uprate conditions [2]. The original CUF of 0.780 was multiplied by a factor to obtain a CUF of 0.852 for power uprate conditions.
The latest calculations [3, 4] performed utilized a detailed finite element model to determine the CUFs for 60-year plant operation. The stresses in the CRD nozzle region were obtained by the use of ANSYS computer program and this finite elementmodel. The stresses developed reflect the actual geometry and the loading conditions around the CRD nozzle region. These stresses obtained from the finite element analysis are lower compared to the original calculations [1].
- 2. The original calculations [1, 2] assumed that all transients result in the maximum calculated peak stresses. Therefore, all transient cycles were added together and this total was divided by the allowable number of cycles based on the maximum alternating stress. This is very conservative.
The latest calculations [3, 4] take into account all different transients and determine stresses and allowable cycles based on each transient. This yields in a lower CUF than the conservative methodology used in the original calculations [1, 2].

- b. Post trip computer edits if available
- c. Recirculation temperature and flow rate strip charts.

- e. Reactor Pressure strip charts.
- f. Balance of plant logs
- g. Closure region tensioning data.B. Provide justification on page 19 of the 6transients that exceeded the original design basis.
These events are considered to be less severe than the original design basis events based on the following reasoning:1) The T's occur over a finite period of time, i.e.they are not instantaneous.
- 2) Whenever data was available from balance of plant logs, it suggested that the temperature changes occurred relatively slowly, i.e. less than
100 o F/hour. Since it is a Technical Specificationsrequirement to shut down or startup the reactor less than or equal to 100 o F/hour this assumptionwas used when data was not available. This is conservative.
- 3) The original analysis (CE analysis) thermal stresses are inherently conservative because they are based on shell interaction equations and use conservative assumptions.Thus, it is considered conservative to use theoriginal design basis thermal stresses for the Question and Answer Database Audit and Review Related to the License Renewal Application for James A.

However, transient conditions stated on page 4 does not include seismic loading. This is due to the fact that the low vertical seismic is compensated by dead weight, resulting in zero tensile stress in the reactor vessel studs.
