Appendix B of the IPEC LRA provides descriptions of the programs and activities that manage the effects of aging for the period of extended operation. Section 4 of the LRA documents the evaluations of time-limited aging analyses for the period of extended operation. Appendix B and Section 4 have been used to prepare the program and activity descriptions for both IP2 and IP3 Updated Final Safety Analysis Reports (UFSAR) Supplement information in this appendix.This appendix is divided into three sections. The first section identifies changes to the existing sections of each UFSAR related to license renewal. The next two sections provide new information to be incorporated into the Unit 2 UFSAR and Unit 3 UFSAR. The information presented in each section will be incorporated into the respective UFSAR following issuance of the renewed operating licenses. Upon inclusion of the UFSAR Supplement in each UFSAR, future changes to the descriptions of the programs and activities will be made in accordance with 10 CFR 50.59.

Indian Point Energy CenterLicense Renewal ApplicationTechnical InformationAppendix A Updated Final Safety Analysis Report SupplementPage A-2A.1CHANGES TO EXISTING UFSAR INFORMATIONThis section identifies changes to existing sections of the Indian Point Energy Center Unit 2 UFSAR that reflect a renewed operating license.

Proposed text deletions are indicated by a strike-through and proposed text additions are indicated by underline.A.1.1IP2 UFSAR Chapter 1 ChangesSection 1.1 Introduction(7th paragraph) The reactor is presently licensed to operate until September 28, 2013. The reactor power plus 12.4 MWt of energy from the reactor coolant pumps give a total rated heat input to the NSSS of 3126.6 MW, which corre sponds to a design electric output from the turbine-generator of approximately 1034.1 MW.A.1.2IP2 UFSAR Chapter 4 ChangesSection 4.1.5 - Cyclic Loads(1st paragraph)During unit startup and shutdown, the rates of temperature and pressure changes are limited as indicated in Section 4.4.1. The cycles are estimated for equipment design purposes (40-year life) and are not intended to be an accurate representation of actual transients or actual operating experience. For example, the number of cycles for plant heatup and cooldown at 100°F per hr was selected as a conservative estimate based on an evaluation of the expected requirements. The resulting number, which averages five heatup and cooldown cycles per year, could be increased significantly; however, it is the intent to represent a conservative realistic number rather than the maximum allowed by the design.Section 4.1.6 - Service Life(5th paragraph)To establish the service life of the reactor coolant system components as required by the ASME (Section III) Boiler and Pressure Vessel Code for Class "A" vessels, the unit operating conditions have been established for the 40-year design licensed life. These operating conditions include the cyclic application of pressure loadings and thermal transients.

The corresponding reactor coolant pressure variation is less than 100 psig. It is assumed that an infinite number of such fluctuations will occur.

Notes:1. Estimated for equipment design purposes (40-yr life) and not intended to be an accurate representation of actual transients, or to reflect actual operating experience.2. This transient includes pressurizing to 2235 psig.

Indian Point Energy CenterLicense Renewal ApplicationTechnical InformationAppendix A Updated Final Safety Analysis Report SupplementPage A-4Section 4.2.2.5 - Reactor Coolant Pump Flywheel Integrity(8th paragraph, bullet 3)A fracture mechanics evaluation (WCAP-15666-A) was made on the reactor coolant pump flywheel. This evaluation justifies operation of the RCPs with flywheel inspections at least every 20 years.This evaluation considered the following assumptions

1. Maximum tangential stress at an assumed overspeed of 125-percent compared with a maximum expected overspeed of 109-percent.2. A through crack through the thickness of the flywheel at the bore. 3. 400 cycles of startup operation in 40 years.

Using critical stress intensity factors and crack growth data attained on flywheel material, the critical crack size for failure was greater than 17-in. radially and the crack growth data was 0.030-in. to 0.060-in. per 1000 cycles.

Section 4.2.5 - Materials of Construction(6th paragraph)The reactor vessel was fabricated by Combustion Engineering, Inc. A sketch of the reactor vessel showing all materials in the beltline region is shown in Figure 4.2-11. Information on each of the welds and plates in the beltline region is shown in Tables 4.2-2 through 4.2-5, and Tables 4.2-5 through 4.2-8, respectively. Information relative to weld and plate material included in the material surveillance program is shown in Tables 4.2-2 and 4.2-6 through 4.2-8. Details concerning the reactor vessel radiation surveillance program are provided in WCAP-7323 (Reference 7) and in the Technical Specifications.(13th paragraph)The maximum integrated fast neutron (E > 1 MeV) exposure of the vessel for 32 EFPYs is calculated to be 1.39 x 10 19 n/cm2 based on the measurements from the fourth surveillance Capsule V. Fast neutron fluences corresponding to 32 EFPYs at various reactor vessel thicknesses are given in Table 4.2-10.For the extended period of operation (60 years), the maximum integrated fast neutron (E > 1 MeV) exposure of the vessel for 48 EFPYs is calculated to be 1.906 x 10 19 n/cm 2 based on calculations using Regulatory Guide 1.99 methodology. Fast neutron fluences corresponding to 48 EFPYs at various reactor vessel thicknesses are given in Table 4.2-10

.

Indian Point Energy CenterLicense Renewal ApplicationTechnical InformationAppendix A Updated Final Safety Analysis Report SupplementPage A-5(14th paragraph) The calculated neutron exposure exceeds the value of 0.85 x 10 19 n/cm 2 (E > 1MeV) reported in the First Supplement to the Preliminary Facility Description Safety Analysis Report. The reasons for the increase are:1.Anticipated increase in reactor power from 2758 MWt to 3071.4 MWt in Cycle 10 and subsequently to 3114.4 MWt in Cycle 16. 2.Revision of analysis methodology including upgrading of neutron cross sections and codes.3.Core design considerations involving changes in loading patterns.

(Ref.11). This data provides the basis for subsequent calculation of Adjusted Reference Temperature values for determination of allowable pressure/temperature limits for operation to 25 EFPY, as described in Reference 19.For the extended period of operation, the maximum reference temperature R TNDT for the Indian Point Unit 2 vessel core beltline materials at the 1/4 thickness and the 3/4 thickness after 48 effective full power years of operation is projected to be 238.3°F and 17 4.8°F, respectively (at circumferential w eld 9-042), based on calculations performed per Regulatory Guide 1.99, Revision 2.(18th paragraph)The reference nil ductility transition temperatures for pressurized thermal shock evaluation (RTPTS) have been estimated11,12,13 in accordance with 10 CFR 50.61(b)(2). The values at 15 EFPY and also at the end of the license term are well below the screening criteria of 270°F (for plates and axial weld materials) and 300°F (for circumferential weld materials), based on a low-leakage core design. The NRC has accepted this analysis.

Similarly, the maximum integrated fast neutron exposure at the 1/4T location was computed to be 5.5 x 10 18 n/cm 2 at EOL (11). With this exposure the end-of-life RTNDT was originally estimated to be 170.6°F, and RTPTS temperature was not expected to be over 268°F, which is bel ow the NRC screening criteria of 270 oF. The maximum integrated fast neutron exposure of the vessel inner surface was computed to be 1.

560 x 10 19 n/cm 2 for the period of extended operation, or 48 effective full power years, at a power of 3216 MWt.

Similarly, the maximum integrated fast neutron exposure at the 1/4T location was computed to be 9.298 x 10 18 n/cm 2 at EOL. With this exposure, the end-of-life 1/4T RT NDT was estimated to be 25 5.8°F (plate B2803-3), and RTPTS temperature was estimated to be 2 79.9°F (plate B2803-3)

, which exceeds the NRC screening criterion of 270 o F. For all other locations

, the RTPTS temperature is projected to be less than the NRC screening criterion

. As required by 10 CFR 50.61(b)(4), a plant-specific safety analysis for plate B2803-3 will be submitted to the NRC three years prior to reaching the RTPTS screening criterion. Each core redesign is evaluated to assure that leakage is less than assumed in analyses to predict the effect of neutron embrittlement.(13th paragraph)The maximum shift in RTNDT after 20 EFPYs of operation is projected to be 230.1°F at the 1/4T and 188.8°F at the 3/4T vessel wall locations for Plate B2803-3 the controlling plate.

The confirmation process is part of the corrective action program and includes reviews to assure that proposed actions are adequate, tracking and reporting of open corrective actions, and review of corrective action effectiveness. Any follow-up inspection required by the c onfirmation process is documented in accordance with the corrective action program. The corrective action, confirmation process, and administrative controls of the Entergy (10 CFR Part 50, Appendix B) Quality Assurance Program are applicable to all aging management programs and activities required during the period of extended operation.

Indian Point Energy CenterLicense Renewal ApplicationTechnical InformationAppendix A Updated Final Safety Analysis Report SupplementPage A-18A.2.1.1Aboveground Steel Tanks ProgramThe Aboveground Steel Tanks Program is an existing program that manages loss of material from external surfaces of aboveground carbon steel tanks by periodic visual inspection of external surfaces and thickness measurement of locations that are inaccessible for external visual inspection. The Aboveground Steel Tanks Program will be enhanced to include the following.

  • Revise applicable procedures to perform thickness measurements of the bottom surfaces of the condensate storage tank, city water tank, and fire water tank, once during the first 10 years of the period of extended operation.
  • Revise applicable procedures to require trending of thickness measurements when material loss is detected.Enhancements will be implemented prior to the period of extended operation.A.2.1.2Bolting Integrity Program The Bolting Integrity Program is an existing program that relies on recommendations for a comprehensive bolting integrity program, as delineated in NUREG-1339, industry recommendations, and Electric Power Research Institute (EPRI) NP-5769, with the exceptions noted in NUREG-1339 for safety-related bolting. The program relies on industry recommendations for comprehensive bolting maintenance, as delineated in EPRI TR-104213 for pressure retaining bolting and structural bolting. The program applies to bolting and torquing practices of safety- and nonsafety-related bolting for pressure retaining components, NSSS component supports, and structural joints. The program addresses all bolting regardless of size except reactor head closure studs, which are addressed by the Reactor Head Closure Studs Program. The program includes periodic inspection of closure bolting for signs of leakage that may be due to crack initiation, loss of preload, or loss of material due to corrosion. The program also includes preventive measures to preclude or minimize loss of preload and cracking. The Bolting Integrity Program will be enhanced to include the following.
  • Revise applicable procedures to clarify that actual yield strength is used in selecting materials for low susceptibility to SCC and to clarify the prohibition on use of lubricants containing MoS 2 for bolting. Enhancements will be implemented prior to the period of extended operation.

Indian Point Energy CenterLicense Renewal ApplicationTechnical InformationAppendix A Updated Final Safety Analysis Report SupplementPage A-19A.2.1.3Boraflex Monitoring ProgramThe Boraflex Monitoring Program is an existing program that assures degradation of the Boraflex panels in the spent fuel racks does not compromise the criticality analysis in support of the design of the spent fuel storage racks. The program relies on (1) areal density testing, (2) use of a predictive computer code, and (3) determination of boron loss through correlation of silica levels in spent fuel water samples to assure that the required 5% subcriticality margin is maintained. Corrective actions are initiated if the test results find that the 5% subcriticality margin cannot be maintained because of current or projected Boraflex degradation.A.2.1.4Boric Acid Corrosion Prevention Program The Boric Acid Corrosion Prevention Program is an existing program that relies on implementation of recommendations of NRC Generic Letter 88-05 to monitor the condition of components on which borated reactor water may leak. The program detects boric acid leakage by periodic visual inspection of systems containing borated water for deposits of boric acid crystals and the presence of moisture; and by inspection of adjacent structures, components, and supports for evidence of leakage. This program manages loss of material and loss of circuit continuity, as applicable. The program includes provisions for evaluation when leakage is discovered by other activities. Program improvements have been made as suggested in NRC Regulatory Issue Summary 2003-013.A.2.1.5Buried Piping and Tanks Inspection Program The Buried Piping and Tanks Inspection Program is a new program that includes (a) preventive measures to mitigate corrosion and (b) inspections to manage the effects of corrosion on the pressure-retaining capability of buried carbon steel, gray cast iron, and stainless steel components. Preventive measures are in accordance with standard industry practice for maintaining external coatings and wrappings. Buried components are inspected when excavated during maintenance. If trending within the corrective action program identifies susceptible locations, the areas with a history of corrosion problems are evaluated for the need for additional inspection, alternate coating, or replacement.Prior to entering the period of extended operation, plant operating experience will be reviewed to verify that an inspection occurred within the past ten years. If an inspection did not occur, a focused inspection will be performed prior to the period of extended operation. 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. The Buried Piping and Tanks Inspection Program will be implemented prior to the period of extended operation.

Indian Point Energy CenterLicense Renewal ApplicationTechnical InformationAppendix A Updated Final Safety Analysis Report SupplementPage A-20A.2.1.6Containment Leak Rate ProgramThe Containment Leak Rate Program is an existing program. As described in 10 CFR Part 50, Appendix J, containment leak rate tests are required to assure that (a) leakage through reactor containment and systems and components penetrating containment shall not exceed allowable values specified in technical specifications or associated bases and (b) periodic surveillance of reactor containment penetrations and isolation valves is performed so that proper maintenance and repairs are made during the service life of containment, and systems and components penetrating containment.A.2.1.7Containment Inservice Inspection (CII) Program The Containment Inservice Inspection Program is an existing program encompassing ASME Section XI Subsection IWE and IWL requirements as modified by 10 CFR 50.55a. Visual inspections for IWE monitor loss of material of the steel containment liner and integral attachments; containment hatches and airlocks; moisture barriers; and pressure- retaining bolting by inspecting surfaces for evidence of flaking, blistering, peeling, discoloration, and other signs of distress. Visual inspections for IWL monitor structural concrete surfaces for evidence of leaching, erosion, voids, scaling, spalls, corrosion, cracking, exposed reinforcing steel, and detached embedment. A.2.1.8Diesel Fuel Monitoring Program The Diesel Fuel Monitoring Program is an existing program that entails sampling to ensure that adequate diesel fuel quality is maintained to prevent loss of material and fouling in fuel systems. Exposure to fuel oil contaminants such as water and microbiological organisms is minimized by periodically draining and cleaning tanks and by verifying the quality of new oil before its introduction into the storage tanks. Sampling and analysis activities are in accordance with technical specifications on fuel oil purity and the guidelines of ASTM Standards D4057-95 and D975-95 (or later revisions of these standards). Thickness measurements of storage tank bottom surfaces verify that significant degradation is not occurring. The One-Time Inspection Program describes inspections planned to verify the effectiveness of the Diesel Fuel Monitoring Program. The Diesel Fuel Monitoring Program will be enhanced to include the following.

  • Revise applicable procedures to include cleaning and inspection of the GT1 gas turbine fuel oil storage tanks, EDG fuel oil day tanks, and SBO/Appendix R diesel generator fuel oil day tank once every ten years.

As required by 10 CFR 50.49, EQ components are refurbished, replaced, or their qualification is extended prior to reaching the aging limits established in the evaluations. Some aging evaluations for EQ components are considered time-limited aging analyses (TLAAs) for license renewal.A.2.1.10External Surfaces Monitoring Program The External Surfaces Monitoring Program is an existing program that inspects external surfaces of components subject to aging management review. The program is also credited with managing loss of material from internal surfaces, for situations in which internal and external material and environment combinations are the same such that external surface condition is representative of internal surface condition.Surfaces that are inaccessible during plant operations are inspected during refueling outages. Surfaces that are insulated are inspected when the external surface is exposed (i.e., during maintenance). Surfaces are inspected at frequencies to assure the effects of aging are managed such that applicable components will perform their intended function during the period of extended operation. The External Surfaces Monitoring Program will be enhanced to include the following.

Indian Point Energy CenterLicense Renewal ApplicationTechnical InformationAppendix A Updated Final Safety Analysis Report SupplementPage A-22

  • Guidance documents will be revised to require periodic inspections of systems in scope and subject to aging management review for license renewal in accordance with 10 CFR 54.4 (a)(1) and (a)(3). Inspections shall include areas surrounding the subject systems to identify hazards to those systems. Inspections of nearby systems that could impact the subject systems will include SSCs that are in scope and subject to aging management review for license renewal in accordance with 10 CFR 54.4 (a)(2).Enhancements will be implemented prior to the period of extended operation.A.2.1.11Fatigue Monitoring Program The Fatigue Monitoring Program is an existing program that tracks the number of critical thermal and pressure transients for selected reactor coolant system components. The program ensures the validity of analyses that explicitly analyzed a specified number of fatigue transients by assuring that the actual effective number of transients does not exceed the analyzed number of transients. The Fatigue Monitoring Program will be enhanced to include the following.
  • Perform an evaluation to confirm that monitoring steady state cycles is not required or revise appropriate procedures to monitor steady state cycles. Review the number of allowed events and resolve discrepancies between reference documents and monitoring procedures.Enhancements will be implemented prior to the period of extended operation.A.2.1.12Fire Protection Program The Fire Protection Program is an existing program that includes a fire barrier inspection, an RCP oil collection system inspection, and a diesel-driven fire pump inspection. The fire barrier inspection requires periodic visual inspection of fire barrier penetration seals, fire barrier walls, ceilings, and floors, and periodic visual inspection and functional tests of fire rated doors to ensure that their operability is maintained. The diesel-driven fire pump inspection requires that the pump and its driver be periodically tested and inspected to ensure that diesel engine sub-systems including the fuel supply line can perform their intended functions. The program also includes periodic inspection and testing of the Halon fire protection system.The Fire Protection Program will be enhanced to include the following.
  • Revise appropriate procedures to explicitly state that the diesel fire pump engine sub-systems (including the fuel supply line) shall be observed while the pump is running. Acceptance criteria will be revised to verify that the diesel engine does not exhibit signs of degradation while it is running; such as fuel oil, lube oil, coolant, or exhaust gas leakage.

Indian Point Energy CenterLicense Renewal ApplicationTechnical InformationAppendix A Updated Final Safety Analysis Report SupplementPage A-23

  • Revise appropriate procedures to specify that diesel fire pump engine carbon steel exhaust components are inspected for evidence of corrosion or cr acking at least once each operating cycle. Enhancements will be implemented prior to the period of extended operation.A.2.1.13Fire Water System Program The Fire Water System Program is an existing program that manages water-based fire protection systems that consist of sprinklers, nozzles, fittings, valves, hydrants, hose stations, standpipes, piping, and components that are tested in accordance with applicable National Fire Protection Association (NFPA) codes and standards. Such testing assures functionality of systems. To determine if significant corrosion has occurred in water-based fire protection systems, periodic flushing, system performance testing and inspections are conducted.

One-time inspections may be needed to address concerns for potentially long incubation periods for certain aging effects on structures and components. There are cases where either (a) an aging effect is not expected to occur but there is insufficient data to completely rule it out, or (b) an aging effect is expected to progress very slowly. For these cases, there will be confirmation that either the aging effect is indeed not occurring, or the aging effect is occurring very slowly as not to affect the component or structure intended function. A one-time inspection of the subject component or structure is appropriate for this verification.The elements of the 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 component based on the aging effect; (c) determination of the examination technique, including acceptance criteria that would be effective in managing the aging effect for which the component is examined; and (d) evaluation of the need for follow-up examinations to monitor the progression of any aging degradation.A one-time inspection activity is used to verify the effectiveness of the water chemistry control programs by confirming that unacceptable cracking, loss of material, and fouling is not occurring on components within systems covered by water chemistry control programs [Sections A.2.1.38 , A.2.1.39, and A.2.1.40].A one-time inspection activity is used to verify the effectiveness of the Oil Analysis Program by confirming that unacceptable loss of material and fouling are not occurring on components within systems covered by the Oil Analysis Program [Section A.2.1.25

The 1/4 T fluences were derived using RG 1.99 formula and conservative wall thicknesses.A.2.2.1.2Pressure-Temperature LimitsAppendix G of 10 CFR 50 requires operation of the reactor pressure vessel be accomplished within established pressure-temperature (P-T) limits. These limits are established by calculations that utilize the materials and fluence data obtained through the unit specific reactor surveillance capsule program. Technical Specifications contain pressure/temperature limits valid through 25 EFPY including the effects of power uprate.The site will submit additional P-T curves as 10 CFR 50, Appendix G requires prior to the period of extended operation as part of the Reactor Vessel Surveillance Program. A.2.2.1.3Charpy Upper-Shelf EnergyThe predictions for percent drop in C VUSE at 48 EFPY are based on chemistry data, unirradiated C VUSE data, and 1/4 T fluence values. The projected 48 EFPY peak beltline fluence level was applied to all beltline materials with the exception of axial welds. Based on surveillance data, peak fluence levels at the beltline axial welds is based on the expected fluence at the 30 degree azimuth position.

Indian Point Energy CenterLicense Renewal ApplicationTechnical InformationAppendix A Updated Final Safety Analysis Report SupplementPage A-40One intermediate shell plate (B2002-3) and one lower shell plate (B2003-1) have projected upper shelf energy levels that fall below 50 ft-lb during the period of extended operation. All remaining plate and weld beltline materials meet the requirement of exceed 50 ft-lb at 48 EFPY.An equivalent margins analysis performed in WCAP-13587, Rev. 1, demonstrated that the minimum acceptable USE for reactor vessel plate material in four-loop plants is 43ft-lbs. In the safety assessment of WCAP-13587, the NRC concluded the report demonstrated margins of safety equivalent to those of the ASME code for beltline plate and forging materials. The USE values are therefore acceptable since the lowest projected USE level for the beltline plate material through the period of extended operation of 47.4 ft-lb for intermediate shell plate B2002-3 is above the 43 ft-lbs minimum acceptable USE for four-loop plants determined in WCAP-13587 Rev. 1. A.2.2.1.4Pressurized Thermal Shock10 CFR 50.61(b)(1) provides rules for protection against pressurized thermal shock events for pressurized water reactors. Licensees are required to perform an assessment of the projected values of reference temperature whenever a significant change occurs in projected values of the adjusted reference temperature for pressurized thermal shock (RTPTS). The screening criteria for RTPTS is 270F for plates, forgings, and axial welds and 300 F for circumferential welds. Adjusted reference temperatures are calculated for both Positions 1 and 2 by following the guidance in Regulatory Guide 1.99, Sections 1.1 and 2.1, respectively, using copper and nickel content of beltline materials and end-of-life (EOL) best estimate fluence projections. All projected RTPTS values are within the established screening criteria at 48 EFPY.A.2.2.2Metal FatigueA.2.2.2.1Class 1 Metal FatigueClass 1 components evaluated for fatigue and flaw growth include the reactor pressure vessel (RPV), reactor vessel internals, pressurizer, steam generators, reactor coolant pumps, control rod drive mechanisms, regenerative letdown heat exchanger, and Class-1 piping and in-line components.The Fatigue Monitoring Program will assure that the analyzed number of transient cycles is not exceeded. The program requires corrective action if the analyzed number of transient cycles is approached. Consequently, the TLAA (fatigue analyses) based on those transients will remain valid for the period of extended operation in accordance with 10 CFR 54.21(c)(1)(i).A.2.2.2.2Non-Class 1 Metal FatigueFor non-Class 1 piping and in-line components identified as subject to cracking due to fatigue, a review of system operating characteristics was conducted to determine the approximate Indian Point Energy CenterLicense Renewal ApplicationTechnical InformationAppendix A Updated Final Safety Analysis Report SupplementPage A-41frequency of any significant thermal cycling. If the number of equivalent full temperature cycles is below the limit used for the original design (usually 7000 cycles), the component is suitable for extended operation. If the number of equivalent full temperature cycles exceeds the limit, the individual stress calculations require evaluation. No systems were identified with projected cycles exceeding 7000. Therefore, the TLAA for non-Class 1 piping and in-line components remain valid for the period of extended operation in accordance with 10 CFR 54.21(c)(i).The only non-Class1, non-piping component identified with a fatigue time-limited aging analysis was the residual heat removal heat exchanger. That heat exchanger is projected to incur less than the analyzed number of cycles and therefore the analysis will remain valid for the period of extended operation.A.2.2.2.3Environmental Effects on FatigueThe effects of reactor water environment on fatigue were evaluated for license renewal. Projected cumulative usage factors (CUFs) were calculated for the limiting locations identified in NUREG/CR-6260. For the locations with CUFs less than 1.0, the TLAA has been projected through the period of extended operation per 10 CFR 54.21(c)(1)(ii). Several locations may exceed a CUF of 1.0 with consideration of environmental effects during the period of extended operation. At least two years prior to entering the period of extended operation, for the locations identified in NUREG/CR-6260 for Westinghouse PWRs of this vintage, the site will implement one or more of the following:(1) Refine the fatigue analyses to determine valid CUFs less than 1 when accounting for the effects of reactor water environment. This includes applying the appropriate F en factors to valid CUFs determined in accordance with one of the following.For locations, including NUREG/CR-6260 locations, with existing fatigue analysis valid for the period of extended operation, use the existing CUF to determine the environmentally adjusted CUF.In addition to the NUREG/CR-6260 locations, more limiting plant-specific locations with a valid CUF may be evaluated. In particular, the pressurizer lower shell will be reviewed to ensure the surge nozzle remains the limiting component.Representative CUF values from other plants, adjusted to or enveloping the plant-specific external loads may be used if demonstrated applicable.

An analysis using an NRC-approved ve rsion of the ASME code or NRC-approved alternative (e.g., NRC-approved code case) ma y be performed to determine a valid CUF.(2) Manage the effects of aging due to fatigue at the affected locations by an inspection program that has been reviewed and approved by the NRC (e.g., periodic non-Indian Point Energy CenterLicense Renewal ApplicationTechnical InformationAppendix A Updated Final Safety Analysis Report SupplementPage A-42destructive examination of the affected locations at inspection intervals to be determined by a method acceptable to the NRC).(3) Repair or replace the affected locations before exceeding a CUF of 1.0.Should the site select the option to manage the aging effects due to environmental-assisted fatigue during the period of extended operation, details of the aging management program such as scope, qualification, method, and frequency will be submitted to the NRC at least two years prior to the period of extended operation.A.2.2.3Environmental Qualification of Electrical Components The EQ Program implements the requirements of 10 CFR 50.49 (as further defined by the Division of Operating Reactors Guidelines, NUREG-0588, and Reg. Guide 1.89). The program requires action before individual components exceed their qualified life. In accordance with 10CFR 54.21(c)(1)(iii), implementation of the EQ Program provides reasonable assurance that the effects of aging on components with EQ TLAAs will be adequately managed such that the intended functions can be maintained for the period of extended operation.A.2.2.4Containment Liner Plate and Penetrations Fatigue Analyses In 1973, a feedwater line cracked circumferentially, resulting in damage to the liner plate causing containment liner plate buckling at the penetration for feedwater line #22. Studies were performed to evaluate the effects of fatigue on the deformed area of the liner due to predicted high strain-limited cycle loading during its projected life. The evaluation was based on the 40-year operating life of the plant and is thus considered a TLAA. The TLAA associated with the buckled liner adjacent to the feedwater line #22 penetration remains valid for the period of extended operation in accordance with 10 CFR 54.21(c)(1)(i).There are no TLAA associated with the containment penetrations.

A.2.2.5Leak before Break Leak before break (LBB) analyses evaluate postulated flaw growth in piping to justify changes to the structural design basis involving protection against the effect of postulated reactor coolant loop pipe ruptures. The LBB evaluations use saturated (fully aged) fracture toughness properties, and these analyses do not have a material property time-limited assumption. The fatigue crack growth for 40 years was calculated using the design transients for the reactor vessel. As these transients will not be exceeded in 60 years, these analyses will remain valid during the period of extended operation in accordance with 10 CFR 54.21(c)(1)(i).A.2.2.6Steam Generator Flow-Induced Vibration and Tube Wear The steam generators were evaluated with respect to flow-induced vibration (tube wear). The replacement steam generators went into service in January 2000 and will have less than 40 Indian Point Energy CenterLicense Renewal ApplicationTechnical InformationAppendix A Updated Final Safety Analysis Report SupplementPage A-43years of service at the end of the period of extended operation (September 2033). Therefore these TLAA will remain valid through the end of the period of extended operation in accordance with 10 CFR 54.21(c)(1)(i).A.2.3References A.2-1[IPEC License Renewal Application-later]

The program relies on industry recommendations for comprehensive bolting maintenance, as delineated in EPRI TR-104213 for pressure retaining bolting and structural bolting. The program applies to bolting and torquing practices of safety- and nonsafety-related bolting for pressure retaining components, NSSS component supports, and structural joints. The program addresses all bolting regardless of size except reactor head closure studs, which are addressed by the Reactor Head Closure Studs Program. The program includes periodic inspection of closure bolting for signs of leakage that may be due to crack initiation, loss of preload, or loss of material due to corrosion. The program also includes preventive measures to preclude or minimize loss of preload and cracking.The Bolting Integrity Program will be enhanced to include the following.

Indian Point Energy CenterLicense Renewal ApplicationTechnical InformationAppendix A Updated Final Safety Analysis Report SupplementPage A-46A.3.1.3Boral Surveillance Program The Boral Surveillance Program is an existing program that provides assurance the Boral neutron absorbers in the spent fuel racks maintain the validity of the criticality analysis in support of the rack design. The program relies on representative coupon samples mounted in surveillance assemblies located in the spent fuel pool to monitor performance of the absorber material without disrupting the integrity of the storage system.Surveillance assemblies are removed from the spent fuel pool on a prescribed schedule and physical and chemical properties are measured. From this data, the stability and integrity of the Boral in the storage cells are assessed.A.3.1.4Boric Acid Corrosion Prevention Program The Boric Acid Corrosion Prevention Program is an existing program that relies on implementation of recommendations of NRC Generic Letter 88-05 to monitor the condition of components on which borated reactor water may leak. The program detects boric acid leakage by periodic visual inspection of systems containing borated water for deposits of boric acid crystals and the presence of moisture; and by inspection of adjacent structures, components, and supports for evidence of leakage. This program manages loss of material and loss of circuit continuity, as applicable. The program includes provisions for evaluation when leakage is discovered by other activities. Program improvements have been made as suggested in NRC Regulatory Issue Summary 2003-013.A.3.1.5Buried Piping and Tanks Inspection Program The Buried Piping and Tanks Inspection Program is a new program that includes (a) preventive measures to mitigate corrosion and (b) inspections to manage the effects of corrosion on the pressure-retaining capability of buried carbon steel, gray cast iron, and stainless steel components. Preventive measures are in accordance with standard industry practice for maintaining external coatings and wrappings. Buried components are inspected when excavated during maintenance. If trending within the corrective action program identifies susceptible locations, the areas with a history of corrosion problems are evaluated for the need for additional inspection, alternate coating, or replacement.Prior to entering the period of extended operation, plant operating experience will be reviewed to verify that an inspection occurred within the past ten years. If an inspection did not occur, a focused inspection will be performed prior to the period of extended operation. 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.The Buried Piping and Tanks Inspection Program will be implemented prior to the period of extended operation.

Indian Point Energy CenterLicense Renewal ApplicationTechnical InformationAppendix A Updated Final Safety Analysis Report SupplementPage A-47A.3.1.6Containment Leak Rate ProgramThe Containment Leak Rate Program is an existing program. As described in 10 CFR Part 50, Appendix J, containment leak rate tests are required to assure that (a) leakage through reactor containment and systems and components penetrating containment shall not exceed allowable values specified in technical specifications or associated bases and (b) periodic surveillance of reactor containment penetrations and isolation valves is performed so that proper maintenance and repairs are made during the service life of containment, and systems and components penetrating containment.A.3.1.7Containment Inservice Inspection (CII) Program The Containment Inservice Inspection (CII) Program is an existing program encompassing ASME Section XI Subsection IWE and IWL requirements as modified by 10 CFR 50.55a. Visual inspections for IWE monitor loss of material of the steel containment liner and integral attachments; containment hatches and airlocks; moisture barriers; and pressure-retaining bolting by inspecting surfaces for evidence of flaking, blistering, peeling, discoloration, and other signs of distress.

As required by 10 CFR 50.49, EQ components exceeding their qualification are refurbished, replaced, or their qualification extended prior to reaching the aging limits established in the evaluations. Some aging evaluations for EQ components are considered time-limited aging analyses (TLAAs) for license renewal.A.3.1.10External Surfaces Monitoring Program The External Surfaces Monitoring Program is an existing program that inspects external surfaces of components subject to aging management review. The program is also credited with managing loss of material from internal surfaces, for situations in which internal and external material and environment combinations are the same such that external surface condition is representative of internal surface condition.Surfaces that are inaccessible during plant operations are inspected during refueling outages. Surfaces that are insulated are inspected when the external surface is exposed (i.e., during maintenance). Surfaces are inspected at frequencies to assure the effects of aging are managed such that applicable components will perform their intended function during the period of extended operation. The External Surfaces Monitoring Program will be enhanced to include the following.
  • Guidance documents will be revised to require periodic inspections of systems in scope and subject to aging management review for license renewal in accordance with 10 CFR 54.4 (a)(1) and (a)(3).

Such testing assures functionality of systems. To determine if significant corrosion has occurred in water-based fire protection systems, periodic flushing, system performance testing and inspections are conducted. Also, many of these systems are normally maintained at required operating pressure and monitored such that leakage resulting in loss of system pressure is immediately detected and corrective actions initiated.In addition, wall thickness evaluations of fire protection piping are periodically performed on system components using non-intrusive techniques (e.g., volumetric testing) to identify loss of material due to corrosion. A sample of sprinkler heads required for 10 CFR 50.48 will be inspected using the guidance of NFPA 25 (2002 Edition) Section 5.3.1.1.1, which states, "Where sprinklers have been in place for 50 years, they shall be replaced or representative samples from one or more sample areas shall be submitted to a recognized testing laboratory for field service testing." This sampling will be repeated every ten years after initial field service testing. The Fire Water System Program will be enhanced to include the following.

This program includes (a) an evaluation to determine critical locations, (b) initial operational inspections to determine the extent of thinning at these locations, and (c) follow-up inspections to confirm predictions. The program specifies repair or replacement of components as necessary.A.3.1.15Flux Thimble Tube Inspection Program The Flux Thimble Tube Inspection Program is an existing program that monitors for thinning of the flux thimble tube wall, which provides a path for the incore neutron flux monitoring system detectors and forms part of the RCS pressure boundary. Flux thimble tubes are subject to loss of material at certain locations in the reactor vessel where flow-induced fretting causes wear at discontinuities in the path from the reactor vessel instrument nozzle to the fuel assembly instrument guide tube. An NDE methodology, such as eddy current testing (ECT), or other similar inspection method is used to monitor for wear of the flux thimble tubes. This program implements the recommendations of NRC Bulletin 88-09, "Thimble Tube Thinning in Westinghouse Reactors".

For structures and components that rely on an AMP, this program will verify effectiveness of the AMP by confirming that unacceptable degradation is not occurring and the intended function of a component will be maintained during the period of extended operation. One-time inspections may be needed to address concerns for potentially long incubation periods for certain aging effects on structures and components. There are cases where either (a) an aging effect is not expected to occur but there is insufficient data to completely rule it out, or (b) an aging effect is expected to progress very slowly. For these cases, there will be confirmation that either the aging effect is indeed not occurring, or the aging effect is occurring very slowly as not to affect the component or structure intended function. A one-time inspection of the subject component or structure is appropriate for this verification.The elements of the 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 component based on the aging effect; (c) determination of the examination technique, including acceptance criteria that would be effective in managing the aging effect for which the component is examined; and (d) evaluation of the need for follow-up examinations to monitor the progression of any aging degradation.A one-time inspection activity is used to verify the effectiveness of the water chemistry control programs by confirming that unacceptable cracking, loss of material, and fouling is not occurring on components within systems covered by water chemistry control programs (Sections A.3.1.38 , A.3.1.39, and A.3.1.40).A one-time inspection activity is used to verify the effectiveness of the Oil Analysis Program by confirming that unacceptable loss of material and fouling are not occurring on components within systems covered by the Oil Analysis Program (Section A.3.1.25

Indian Point Energy CenterLicense Renewal ApplicationTechnical InformationAppendix A Updated Final Safety Analysis Report SupplementPage A-66A.3.2Evaluation of Time-Limited Aging Analyses - Unit 3In accordance with 10 CFR 54.21(c), an application for a renewed license requires an evaluation of time-limited aging analyses (TLAA) for the period of extended operation. The following TLAA have been identified and evaluated to meet this requirement.A.3.2.1Reactor Vessel Neutron Embrittlement The current licensing basis analyses evaluating reduction of fracture toughness of the reactor vessel for 40 years are TLAA. The reactor vessel neutron embrittlement TLAA is summarized below. Forty-eight effective full-power years (EFPY) are projected for the end of the period of extended operation (60 years) based on actual capacity factors from the start of commercial operation until 2005 and an average capacity factor of 95% from 2005 to the end of the period of extended operation.A.3.2.1.1Reactor Vessel FluenceAs part of the stretch power uprate analysis, the neutron exposure levels for the reactor pressure vessel were projected for an operating period extending to 48 EFPY.

These fluence values included peak vessel ID fluences. The 1/4 T fluence was derived using RG 1.99 formula and conservative wall thicknesses.A.3.2.1.2Pressure-Temperature LimitsAppendix G of 10 CFR 50 requires operation of the reactor pressure vessel be accomplished within established pressure-temperature (P-T) limits. These limits are established by calculations that utilize the materials and fluence data obtained through the unit specific reactor surveillance capsule program.Technical Specifications contain pressure/temperature limits valid through 34 EFPY including the effects of power uprate. The site will submit additional P-T curves as 10 CFR 50, Appendix G requires prior to the period of extended operation as part of the Reactor Vessel Surveillance Program. A.3.2.1.3Charpy Upper-Shelf EnergyThe predictions for percent drop in C VUSE at 48 EFPY are based on chemistry data, unirradiated C VUSE data, and 1/4 T fluence values. The projected 48 EFPY peak beltline fluence level was conservatively applied to all beltline materials. All plate and weld beltline materials meet the requirement of exceeding a C VUSE value of 50 ft-lb at 48 EFPY.

Indian Point Energy CenterLicense Renewal ApplicationTechnical InformationAppendix A Updated Final Safety Analysis Report SupplementPage A-67A.3.2.1.4Pressurized Thermal Shock10 CFR 50.61(b)(1) provides rules for protection against pressurized thermal shock events for pressurized water reactors. Licensees are required to perform an assessment of the projected values of reference temperature whenever a significant change occurs in projected values of the adjusted reference temperature for pressurized thermal shock (RTPTS). The screening criteria for RTPTS is 270F for plates, forgings, and axial welds and 300 F for circumferential welds. Adjusted reference temperatures are calculated for both Positions 1 and 2 by following the guidance in Regulatory Guide 1.99, Sections 1.1 and 2.1, respectively, using copper and nickel content of beltline materials and end-of-life (EOL) best estimate fluence projections.All projected RTPTS values are within the established screening criteria for 48 EFPY with the exception of plate B2803-3, which exceeds the screening criterion by 9.9 F.As required by 10 CFR 50.61(b)(4), a plant-specific safety analysis for plate B2803-3 will be submitted to the NRC three years prior to reaching the RTPTS screening criterion. Alternatively, the site may choose to implement the revised PTS (10 CFR 50.61) rule when approved, which would permit use of Regulatory Guide 1.99, Revision 3. Application of Regulatory Guide 1.99, Revision 3, to plate B2803-3 is expected to result in an acceptably low probability of a through-wall crack at 48 EFPY.A.3.2.2Metal Fatigue A.3.2.2.1Class 1 Metal FatigueClass 1 components evaluated for fatigue and flaw growth include the reactor pressure vessel (RPV), reactor vessel internals, pressurizer, steam generators, reactor coolant pumps, control rod drive mechanisms, regenerative letdown heat exchanger, and Class-1 piping and in-line components.The Fatigue Monitoring Program will assure that the analyzed number of transient cycles is not exceeded. The program requires corrective action if the analyzed number of transient cycles is approached. Consequently, the TLAA (fatigue analyses) based on those transients will remain valid for the period of extended operation in accordance with 10 CFR 54.21(c)(1)(i).A.3.2.2.2Non-Class 1 Metal FatigueFor non-Class 1 piping and in-line components identified as subject to cracking due to fatigue, a review of system operating characteristics was conducted to determine the approximate frequency of any significant thermal cycling. If the number of equivalent full temperature cycles is below the limit used for the original design (usually 7000 cycles), the component is suitable for extended operation. If the number of equivalent full temperature cycles exceeds the limit, the individual stress calculations require evaluation. No systems were identified with projected Indian Point Energy CenterLicense Renewal ApplicationTechnical InformationAppendix A Updated Final Safety Analysis Report SupplementPage A-68cycles exceeding 7000. Therefore, the TLAA for non-Class 1 piping and in-line components remain valid for the period of extended operation in accordance with 10 CFR 54.21(c)(i).The only non-Class1, non-piping component, identified with a fatigue time-limited aging analysis was the residual heat removal heat exchanger. That heat exchanger is projected to incur less than the analyzed number of cycles and therefore the analysis will remain valid for the period of extended operation.A.3.2.2.3Environmental Effects on FatigueThe effects of reactor water environment on fatigue were evaluated for license renewal. Projected cumulative usage factors (CUFs) were calculated for the limiting locations identified in NUREG/CR-6260. For the locations with CUFs less than 1.0, the TLAA has been projected through the period of extended operation per 10 CFR 54.21(c)(1)(ii). Several locations may exceed a CUF of 1.0 with consideration of environmental effects during the period of extended operation. At least two years prior to entering the period of extended operation, for the locations identified in NUREG/CR-6260 for Westinghouse PWRs of this vintage, the site will implement one or more of the following:(1) Refine the fatigue analyses to determine valid CUFs less than 1 when accounting for the effects of reactor water environment. This includes applying the appropriate F en factors to valid CUFs determined in accordance with one of the following.For locations, including NUREG/CR-6260 locations, with existing fatigue analysis valid for the period of extended operation, use the existing CUF to determine the environmentally adjusted CUF.In addition to the NUREG/CR-6260 locations, more limiting plant-specific locations with a valid CUF may evaluated. In particular, the pressurizer lower shell will be reviewed to ensure the surge nozzle remains the limiting component.Representative CUF values from other plants, adjusted to or enveloping the plant-specific external loads may be used if demonstrated applicable.

An analysis using an NRC-approved ve rsion of the ASME code or NRC-approved alternative (e.g., NRC-approved code case) ma y be performed to determine a valid CUF.(2) Manage the effects of aging due to fatigue at the affected locations by an inspection program that has been reviewed and approved by the NRC (e.g., periodic non-destructive examination of the affected locations at inspection intervals to be determined by a method acceptable to the NRC).(3) Repair or replace the affected locations before exceeding a CUF of 1.0.

Indian Point Energy CenterLicense Renewal ApplicationTechnical InformationAppendix A Updated Final Safety Analysis Report SupplementPage A-69Should the site select the option to manage the aging effects due to environmental-assisted fatigue during the period of extended operation, details of the aging management program such as scope, qualification, method, and frequency will be submitted to the NRC at least two years prior to the period of extended operation.A.3.2.3Environmental Qualification of Electrical Components The EQ Program implements the requirements of 10 CFR 50.49 (as further defined by the Division of Operating Reactors Guidelines, NUREG-0588, and Reg. Guide 1.89). The program requires action before individual components exceed their qualified life. In accordance with 10CFR 54.21(c)(1)(iii), implementation of the EQ Program provides reasonable assurance that the effects of aging on components associated with EQ TLAAs will be adequately managed such that the intended functions can be maintained for the period of extended operation.A.3.2.4Containment Liner Plate and Penetrations Fatigue Analyses There are no TLAA associated with the containment liner plate or the containment penetrations.A.3.2.5Leak before BreakLeak before break (LBB) analyses evaluate postulated flaw growth in piping to justify changes to the structural design basis involving protection against the effect of postulated reactor coolant loop pipe ruptures. The LBB evaluations use saturated (fully aged) fracture toughness properties, these analyses do not have a material property time-limited assumption. The fatigue crack growth for 40 years was calculated using the design transients for the reactor vessel. As these transients will not be exceeded in 60 years, these analyses will remain valid during the period of extended operation in accordance with 10 CFR 54.21(c)(1)(i).A.3.2.6Steam Generator Flow-Induced Vibration and Tube Wear The steam generators were evaluated with respect to flow-induced vibration. The projected tube wear is 2.8 mils (~5.7% through-wall wear) by the end of the period of extended operation. Therefore, the TLAA associated with tube wear has been projected to the end of the period of extended operation in accordance with 10 CFR 54(21)(c)(1)(ii).A.3.3References A.3-1[IPEC License Renewal Application-later]
