System Description

Containment penetrations is not an independent system but is a grouping of containment penetration components not evaluated with other systems. Mechanical penetrations for systems with a system-level aging management review are evaluated with that system.

The scope of this evaluation is passive mechanical penetration components not included in other system evaluations. This evaluation includes only the containment penetration portion of these systems.

The grouping of containment isolation valves from various plant systems into one consolidated review is appropriate, as stated in NUREG-1800, StandardReview Plan for Review of License Renewal Applications for Nuclear Power Plants,Section 2.1.3.1.

NL-14-146 Page 9 of 21 Dockets 50-247 and 50-286 Attachment 1 Containment penetrations have the following intended function for 10CFR54.4(a)(1).

- Prevent release of radioactivity to outside environment.

System Description

Unit2 Instrument Air The compressed air system includes the instrument air (IA) and station air (SA) subsystems.

The purpose of the IA system is to provide a continuous supply of dry, oil-free air for pneumatic instruments and controls. Instrument air is provided by duplicate compressors with duplicate dryers and filters. In addition, alternate supplies are provided from the Unit 2 station air system and Unit 1 station air system. A connection has been provided in the station air system to allow a backup supply of air from portable compressed air equipment. The instrument air system, although designed to meet air capacity requirements, utilizes the higher capacity Unit 1 station air compressors as a primary source of air supply. Because of the high capacity output capability of the Unit 1 air compressors, Unit 2 is able to utilize the Unit 1 air compressors for all Unit 1 and 2 station and instrument air requirements. Unit 2 station air compressor and both Unit 2 instrument air compressors serve as backups. The system includes the compressors, dryers, filters, receivers, distribution piping and valves, instruments and controls.

NL-14-146 Page 11 of 21 Dockets 50-247 and 50-286 Attachment I Those items essential for safe operation and safe cooldown are provided with air reserves or gas bottles. These supplies enable the equipment to function in a safe manner until the air supply is reestablished. The IA system includes piping, air bottles, valves and controls supporting this air reserve function, but does not include all of the air or gas bottles, which are part of other systems. The system may also be used to provide air to the post-accident venting system to pressurize containment in support of hydrogen control, but this is not a safety-related function.

The IA System provides the capability to isolate air to the speed controller for the charging pump (the 21 pump in the chemical and volume control system) from the central control room (CCR), enabling the pump to run at high speed. Adiustment of the charging pump to maximum speed is necessary to establish the required charging flow rate credited in the IP2 Appendix R basis thermal-hydraulic analysis.

The IA system has the following intended functions for 10 CFR 54.4(a)(3).

  • Provide a backup source of compressed gas for pneumatically operated components for the Appendix R event (10 CFR 50.48).
  • Enable charginq pump 21 to be run at high speed without the need for operator actions outside the CCR in response to a fire for the ADpendix R event (10 CFR 50.48).

Flow control APPENDIX A A.0 INTRODUCTION 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

NL-14-146 Page 14 of 21 Dockets 50-247 and 50-286 Attachment I licenses. Upe.RWith inclusion of the UFSAR Supplement in each-the UFSAR, future changes to the descriptions of the programs and activities will be made in accordance with 10 CFR 50.59.

A.2.0 SunDlement for Renewed Ogeratina License The Indian Point Energy Center license renewal application ( Reference A.2-1 ) and information in subsequent related correspondence provided sufficient basis for the NRC to make the findings required by 10 CFR 54.29 (.Final Safety Evaluation Report) ( Reference A.2-2 ). As required by 10 CFR 54.21(d), this UFSAR supplement contains a summary description of the programs and activities for managing the effects of aging (Section A.2.1) and a description of the evaluation of time-limited aging analyses for the period of extended operation ( Section A.2.2). The period of extended operation is the 20 years after the expiration date of the original operating license.

A.2.1.5 Buried Piping and Tanks Inspection Program IP2 will perform 20 direct visual inspections of buried piping during the 10 year period prior to the PEO. IP2 will perform 14 direct visual inspections during each 10-year period of the PEO. Soil samples will be taken prior to the PEO and at least once every 10 years in the PEO. Soil will be tested at a minimum of two locations at least three feet below the surface near in-scope piping to determine representative soil conditions for each system. If test results indicate the soil is corrosive then the number of piping inspections will be increased to 20 during each 10-year period of the PEO.

A.2.1.11 Fatigue 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 program provides for update of the fatigue usage calculations to maintain a cumulative use factor LCUF) of < 1.0 for the period of

NL-14-146 Page 15 of 21 Dockets 50-247 and 50-286 Attachment 1 extended operation. For the locations identified in Section A.2.2.2.43, updated calculations will account for the effects of the reactor water environment.

(Section A.2.2.2.3 revised to A.2.2.2.4)

A.2.1.16 Heat Exchanger Monitoring Program The Heat Exchanger Monitoring Program is an existing plant-specific program that inspects heat exchangers for loss of material through visual or other non-destructive examination.

The Heat Exchanger Monitoring Program will be enhanced to include the following.

- Revise appropriate procedures to perform visual inspection on heat exchangers where non-destructive examination, such as eddy current inspection, is not possible due to heat exchanger design limitations.

A.2.1.17 Inservice Inspection - Inservice Inspection (ISI) Program The ISI Program is an existing program based on ASME Section Xl Inspection Program B (Section Xl, IWA-2432), which has 10-year inspection intervals. Every 10 years the program is updated to the latest ASME Section Xl code edition and addendum approved in 10 CFR 50.55a.

The program consists of periodic volumetric, surface, and visual examination of components and their supports for assessment of signs of degradation, flaw evaluation, and corrective actions.

A.2.1.19 Metal-Enclosed Bus Inspection Program The Metal-Enclosed Bus Inspection Program is an existing program that performs inspections on the following non-segregated phase buses.

NL-14-146 Page 16 of 21 Dockets 50-247 and 50-286 Attachment I A.2.1.23 Non-EQ Instrumentation Circuits Test Review Program The Non-EQ Instrumentation Circuits Test Review Program is a new program that assures the intended functions of sensitive, high-voltage, low-signal cables exposed to adverse localized equipment environments caused by heat, radiation and moisture- (i.e.,

neutron flux monitoring instrumentation and high range radiation monitors)y can be maintained consistent with the current licensing basis through the period of extended operation. Most sensitive instrumentation circuit cables and connections are included in the instrumentation loop calibration at the normal calibration frequency, which provides sufficient indication of the need for corrective actions based on acceptance criteria related to instrumentation loop performance. The review of calibration results will be performed once every ten years, with the first review occurring before the period of extended operation.

(Delete semicolon after moisture)

A.2.1.26 One-Time Inspection Program The One-Time Inspection Program is a new program that includes measures to verify effectiveness of an aging management program (AMP) and confirm the absence of an aging effect. 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 so 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 inspections will be nondestructive examinations (including visual, ultrasonic, and surface techniques).One-time inspection activities on the following confirm that loss of material is not occurring or is so insignificant that an aging management program is not warranted.

One-time inspection activities on the following confirm that loss of material is not occurring or is so insignificant that an aging management program is not warranted.

A.2.1.41 Reactor Vessel Internals Aging Management Activities The IPEC RVI Program will be implemented and maintained in accordance with the guidance in NEI 03-08 [Addenda], Addendum A, "RCS Materials Degradation Management Program Guidelines." Any deviations from mandatory, needed, or good practice implementation requirements established in MRP-227-A or MRP-228-7 will be resolved in accordance with the NEI 03-08 implementation protocol. The RVI Program will be implemented prior to the period of extended operation.

NL-14-146 Page 18 of 21 Dockets 50-247 and 50-286 Attachment I A.2.2.1.3 Charoy Upoer-Shelf Enerav One 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 or exceed the requirement of exGeed 50 ft-lb at 48 EFPY.

An equivalent margins analysis performed in WCAP-1 3587, Rev. 1, demonstrated that the minimum acceptable USE for reactor vessel plate material in four-loop plants is 43 ft-4bsft-lb. 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 48.3 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.2.2.2.1 Class 1 Metal Fatiaue Class 1 components evaluated for fatigue and flaw growth include the reactor pressure vessel (RPV), pressurizer, steam generators, reactor coolant pumps, control rod drive mechanisms, regenerative letdown heat exchanger, and Class 1 piping and in-line components.

A.2.2.6 Steam 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 years 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).

The review of calibration results will be performed once every ten years, with the first review occurring before the period of extended operation.

(Deleted semicolons) 4.2.3 Pressure-Temierature Limits Appendix G of 10 CFR 50 requires operation of the reactor pressure vessel 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

NL-14-146 Page 20 of 21 Dockets 50-247 and 50-286 Attachment I surveillance capsule program. Normally, the pressure-temperature limits are calculated for several years into the future and remain valid for an established period of time.

Technical Specifications contain pressure/temperature limits and LTOP requirements valid through 26 48EFPY including the effects of the stretch power uprate.

A.2.2.1.2 Pressure-Temperature Limits Appendix 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 and LTOP requirements valid through 2.48 EFPY including the effects of power uprate.

NL-14-146 Page 21 of 21 Dockets 50-247 and 50-286 Attachment I 2.3.3.19 Miscellaneous Systems in Scope for (a)(2)

As discussed in Sections 2.1.1.2 and 2.1.2.1.2, systems within the scope of license renewal based on the criterion of 10 CFR 54.4(a)(2) interact with safety-related systems in one of two ways: functional or physical. A functional failure is one where the failure of a nonsafety-related SSC to perform its function, impacts a safety function. A physical failure is one where a safety function is impacted by the loss of structural or mechanical integrity of an SSC in physical proximity to equipment that supports the safety function.

iL2 The following Unit 2 systems are within the scope of license renewal based on the criterion of 10 CFR 54.4(a)(2) and are not described elsewhere in the application.

Miscellaneous The miscellaneous (MSCL) system code includes a variety of structural, electrical and mechanical components with no collective purpose. Mechanical components within the system code include a water heater and filter/pump for the asbestos decon facility, and a small number of valves, primarily from sump aRd-sewage flowpaths.
