INTRODUCTION 1.1 Aging Management Program Inspection Plan The EPRI MRP guidelines define a supplemental inspection program for managing aging effects on the reactor vessel internals and were used to develop this inspection plan for IPEC Units 2 and 3. The EPRI MRP Reactor Internals Focus Group developed the MRP-227 Guidelines to support the demonstration of continued functionality, with requirements for inspections to detect the effects of aging along with requirements for the evaluation of detected aging effects, if any.

The development ofMRP-227 combined the results of component functionality assessments with component accessibility, operating experience, existing evaluations and prior examination results to determine the appropriate aging management methods, initial examination timing and the need and timing of subsequent inspections and identified the components and locations for supplemental examination.

In accordance with MRP-227, this inspection plan includes:

Identification of items for inspection,

Specification of the type of examination appropriate for each degradation mechanism,

Specification of the required level of examination qualification,

Schedule of initial inspection and frequency of subsequent inspections,

Criteria for sampling and coverage,

Criteria for expansion of scope if unanticipated indications are found,

Inspection acceptance criteria,

Methods for evaluating examination results not meeting the acceptance criteria,

Updating the program based on industry-wide results, and

Contingency measures to repair, replace or mitigate.

BACKGROUND OF IPEC REACTOR VESSEL INTERNALS DESIGN This section provides a summary of the design characteristics for the IPEC Westinghouse PWR internals.

2.1 Westinghouse Internals Design Characteristics A schematic view of a typical set of Westinghouse-designed PWR internals is Figure 2-1. More detailed views of selected internals components are Figures 2-2 through 2-16 at the end of this section. These figures are typical and are not an exact representation of the IPEC internals.

To help in the categorization ofIPEC internals design characteristics as discussed in MRP-227 Section 3.1.3, the following information is provided. IPEC Units 2 and 3 are Westinghouse four loop plants with a downflow baffle-barrel region flow design, and a top hat design upper support plate. Unit 2 had an original thermal output of 2758 MWth and Unit 3 had an original thermal output of3025 MWth.

NL-ll-I07 Docket Nos. 50-247 and 50-286 Attachment 1 Indian Point Energy Center Reactor Vessel Internals Inspection Plan Westinghouse internals consist of two basic assemblies: an upper internals assembly that is removed during each refueling operation to obtain access to the reactor core and a lower internals assembly that can be removed following a complete core off-load.

The reactor core is positioned and supported by the upper internals and lower internals assemblies. The individual fuel assemblies are positioned by fuel alignment pins in the upper core plate and the lower core plate. These pins control the orientation of the core with respect to the upper and lower internals assemblies. The lower internals are aligned with the upper internals by the upper core plate alignment pins and secondarily by the head/vessel alignment pins. The lower internals are aligned to the vessel by the lower radial support/clevis assemblies and by the head/vessel alignment pins. Thus, the core is aligned with the vessel by a number of interfacing components.

The lower internals assembly is supported in the vessel by clamping to a ledge below the vessel-head mating surface and is closely guided at the bottom by radial support/clevis assemblies. The upper internals assembly is clamped at this same ledge by the reactor vessel head. The bottom of the upper internals assembly is closely guided by the core barrel alignment pins of the lower internals assembly.

Upper Internals Assembly The major sub-assemblies that constitute the upper internals assembly are the: (1) upper core plate (UCP); (2) upper support column assemblies; (3) control rod guide tube assemblies; and (4) upper support plate (USP).

During reactor operation, the upper internals assembly is preloaded against the fuel assembly springs and the internals hold down spring by the reactor vessel head pressing down on the outside edge of the USP. The USP acts as the divider between the upper plenum and the reactor vessel head and as a relatively stiff base for the rest of the upper internals. The upper support columns and the control rod guide tubes are attached to the USP. The UCP, in tum, is attached to the upper support columns. The USP design at IPEC is designated as a top hat design.

The UCP is perforated to permit coolant to pass from the core below into the upper plenum between the USP and the UCP. The coolant then exits through the outlet nozzles in the core barrel. The UCP positions and laterally supports the core by fuel alignment pins extending below the plate. The UCP contacts and preloads the fuel assembly springs and thus maintains contact of the fuel assemblies with the lower core plate (LCP) during reactor operation.

The upper support columns vertically position the UCP and are designed to take the uplifting hydraulic flow loads and fuel spring loads on the UCP. The control rod guide tubes are bolted to the USP and pinned at the UCP so they can be easily removed if replacement is desired. The control rod guide tubes are designed to guide the control rods in and out of the fuel assemblies to control power generation. Guide tube cards are located within each control rod guide tube Page 4 OAGI0001350 00007

NL-ll-I07 Docket Nos. 50-247 and 50-286 Attachment 1 Indian Point Energy Center Reactor Vessel Internals Inspection Plan to guide the absorber rods. The control rod guide tubes are also slotted in their lower sections to allow coolant exiting the core to flow into the upper plenum.

The upper instrumentation columns are bolted to the USP. These columns support the thermocouple guide tubes that lead the thermocouples from the reactor head through the upper plenum to just above the UCP.

The UCP alignment pins locate the UCP laterally with respect to the lower internals assembly.

The pins must laterally support the UCP so that the plate is free to expand radially and move axially during differential thermal expansion between the upper internals and the core barrel. The UCP alignment pins are the interfacing components between the UCP and the core barrel.

Lower Internals Assembly The fuel assemblies are supported inside the lower internals assembly on top of the LCP. The functions of the LCP are to position and support the core and provide a metered control of reactor coolant flow into each fuel assembly. The LCP is elevated above the lower support casting by support columns and bolted to a ring support attached to the inside diameter of the core barrel. The support columns transmit vertical fuel assembly loads from the LCP to the much thicker lower support casting. The function of the lower support casting is to provide support for the core. The lower support casting is welded to and supported by the core barrel, which transmits vertical loads to the vessel through the core barrel flange.

The primary function of the core barrel is to support the core. A large number of components are attached to the core barrel, including the baffle/former assembly, the core barrel outlet nozzles, the thermal shields, the alignment pins that engage the UCP, the lower support casting, and the LCP. The lower radial support/clevis assemblies restrain large transverse motions of the core barrel but at the same time allow unrestricted radial and axial thermal expansion.

The baffle and former assembly consists of vertical plates called baffles and horizontal support plates called formers. The baffle plates are bolted to the formers by the baffle/former bolts, and the formers are attached to the core barrel inside diameter by the barrel/former bolts. Baffle plates are secured to each other at selected corners by edge bolts. In addition, at IPEC, corner brackets are installed behind and bolted to the baffle plates. The baffle/former assembly forms the interface between the core and the core barrel. The baffles provide a barrier between the core and the former region so that a high concentration of flow in the core region can be maintained.

A secondary benefit is to reduce the neutron flux on the vessel.

The function of the core barrel outlet nozzles is to direct the reactor coolant, after it leaves the core, radially outward through the reactor vessel outlet nozzles. The core barrel outlet nozzles are located in the upper portion of the core barrel directly below the flange and are attached to the core barrel, each in line with a vessel outlet nozzle.

Page 5 OAGI0001350 00008

NL-ll-I07 Docket Nos. 50-247 and 50-286 Attachment 1 Indian Point Energy Center Reactor Vessel Internals Inspection Plan Additional neutron shielding of the reactor vessel is provided in the active core region by thermal shields attached to the outside of the core barrel.

A flux thimble is a long, slender stainless steel tube that passes from an external seal table, through a bottom mounted nozzle penetration, through the lower internals assembly, and finally extends to the top of a fuel assembly. The flux thimble provides a path for a neutron flux detector into the core and is subjected to reactor coolant pressure and temperature on the outside surface and to atmospheric conditions on the inside. The flux thimble path from the seal table to the bottom mounted nozzles is defined by flux thimble guide tubes, which are part of the primary pressure boundary and not part of the internals. The bottom-mounted instrumentation (BMI) columns provide a path for the flux thimbles from the bottom of the vessel into the core. The BMI columns align the flux thimble paths with instrumentation thimbles in the fuel assembly.

In the upper internals assembly, the upper support plate, the upper support columns, and the upper core plate are considered core support structures. In the lower internals assembly, the lower core plate, the lower support casting, the lower support columns, the core barrel including the core barrel flange, the radial support/clevis assemblies, the baffle plates, and the former plates are classified as core support structures.

INSPECTION PLAN

SUMMARY

Management of component aging effects includes actions to prevent or control aging effects, review of operating experience to better understand the potential for aging effects to occur, inspections to detect the onset of aging effects in susceptible components, protocols for evaluation and remediation of the effects of aging, and procedures to ensure component aging effects are managed in a coordinated program.

3.1 Component Inspection and Evaluation Overview This discussion summarizes the guidance of the MRP Inspection & Evaluation (I&E) guidelines necessary to understand implementation but does not duplicate the full discussion of the technical bases. MRP-227 and its supporting documents provide further information on the technical bases of the program.

MRP-227 establishes four groups of reactor internals components with respect to inspections:

Primary, Expansion, Existing Programs and No Additional Measures, as summarized below.

Primary: Those PWR internals that are highly susceptible to the effects of at least one of the eight aging mechanisms were placed in the Primary group. The aging management requirements that are needed to ensure functionality of Primary components are described in the I&E guidelines. The Primary group also includes components which have shown a degree of tolerance to a specific aging degradation effect, but for which no highly susceptible component exists or for which no highly susceptible component is accessible.

Expansion: Those PWR internals that are highly or moderately susceptible to the effects of at least one of the eight aging mechanisms, but for which a functionality assessment has shown a degree of tolerance to those effects, were placed in the Expansion group. The schedule for implementation of aging management requirements for Expansion components will depend on the findings from the examinations of the Primary components.

Existing Programs: Those PWR internals that are susceptible to the effects of at least one of the eight aging mechanisms and for which generic and plant-specific existing AMP elements are capable of managing those effects, were placed in the Existing Programs group.

No Additional Measures: Those PWR internals for which the effects of all eight aging mechanisms are below the screening criteria were placed in the No Additional Measures group. Items categorized as Category A in MRP-191 are those for which aging effects are below the screening criteria, so that aging degradation significance is minimal. Primary, expansion, and Page 19 OAGI0001350 00022

NL-ll-I07 Docket Nos. 50-247 and 50-286 Attachment 1 Indian Point Energy Center Reactor Vessel Internals Inspection Plan existing examinations verify that the chemical control program has been effective at controlling stress corrosion cracking and loss of material due to corrosion for Category A components.

Additional components were placed in the No Additional Measures group as a result of Failure Modes, Effects and Criticality Analysis (FMECA) and the functionality assessment. No further action is required for managing the aging of the No Additional Measures components. However, any core support structures subject to ASME Section XI Examination Category B-N-3 requirements continue to be subj ect to those ASME Code requirements throughout the period of extended operation.

The inspections required for Primary and Expansion components were selected from visual, surface and volumetric examination methods that are applicable and appropriate for the expected degradation effect (e.g. cracking caused by particular mechanisms, loss of material caused by wear). The inspection methods include: Visual examinations (VT-3, VT-I, EVT-I), surface examinations, volumetric examinations (specifically UT) and physical measurements. MRP-227 provides detailed justification for the components selected for inspection and the specific examination methods selected for each. The MRP-228 report, PWR Internals Inspection Standards, provides detailed examination standards and any inspection technical justification or inspection personnel training requirements.

3.2 Inspection and Evaluation Requirements for Primary Components The inspection requirements for Primary Components at IPEC Units 2 and 3 from MRP-227 are provided in Table 5-2.

3.3 Inspection and Evaluation Requirements for Expansion Components The inspection requirements for Expansion Components at IPEC Units 2 and 3 from MRP-227 are provided in Table 5-3.

3.4 Inspections of Existing Program Components The list of Existing Program Components at IPEC Units 2 and 3 from MRP-227 are provided in Table 5-4. This includes components in the Section XI lSI Program for IPEC Units 2 and 3 designated as B-N-2 and B-N-3 locations.

The Reactor Vessel Component Inspection Plan conducted as part of the lSI program for IPEC Units 2 and 3 is provided in Table 5-6. The components are inspected as part of the lSI Program.

The lSI Program inspections are implemented in accordance with ASME Section XI schedule requirements.

NL-ll-I07 Docket Nos. 50-247 and 50-286 Attachment 1 Indian Point Energy Center Reactor Vessel Internals Inspection Plan 3.5 Examination Systems Equipment, techniques, procedures and personnel used to perform examinations required under this program will be consistent with the requirements ofMRP-228. Indications detected during these examinations will be characterized and reported in accordance with the requirements of MRP-228.

3.6 Information Supplied in Response to the NRC Safety Evaluation of MRP-227 As part of the NRC Final Safety Evaluation ofMRP-227, a number of action items and conditions were specified by the staff. Table 5-8 documents the IPEC response to the NRC Final Safety Evaluation ofMRP-227. Wherever possible, these items have been addressed in the appropriate sections of this document. All NRC action items and conditions not addressed elsewhere in this document are discussed in this section.

SER Section 4.2.1, Applicant/Licensee Action Item 1 IPEC has assessed its plant design and operating history and has determined that MRP-227 is applicable to the facility. The assumptions regarding plant design and operating history made in MRP-191 are appropriate for IPEC and there are no differences in component inspection categories at IPEC. IPEC Unit 2 (IP2) had the first 8 years of operation with a high leakage core loading pattern. IPEC Unit 3 (IP3) had the first 10 years of operation with a high leakage core loading pattern. The FMECA and functionality analyses were based on the assumption of30 years of operation with high leakage core loading patterns; therefore, IPEC is bounded by the assumptions in MRP-191. IPEC has always operated as a base-load plant which operates at fixed power levels and does not vary power on a calendar or load demand schedule.

SER Section 4.2.2, Applicant/Licensee Action Item 2 IPEC reviewed the information in Table 4-4 ofMRP-191 and determined that this table contains all of the RVI components that are within the scope oflicense renewal. This is shown in Table 5-7.

SER Section 4.2.3, Applicant/Licensee Action Item 3 At IP2, the original X750 guide tube support pins (split pins) were replaced in 1995 with an improved X750 Revision B material made from more selective material with more continuous carbide coverage grain boundaries and tighter quality controls, to provide greater resistance to stress corrosion cracking. At IP3 the original X750 guide tube support pins (split pins) were replaced in 2009 (after 33 years in service) with cold-worked 316 stainless steel. The cold-worked 316 stainless steel is a significant improvement over the X750. At IPEC the effects of Page 21 OAGI0001350 00024

NL-ll-I07 Docket Nos. 50-247 and 50-286 Attachment 1 Indian Point Energy Center Reactor Vessel Internals Inspection Plan aging on these components will be managed in the period of extended operation based on industry experience and plant specific evaluations.

SER Section 4.2.4, Applicant/Licensee Action Item 4 This action item does not apply to Westinghouse designed units.

SER Section 4.2.5, Applicant/Licensee Action Item 5 The IPEC plant specific acceptance criteria for hold down springs and an explanation of how the proposed acceptance criteria are consistent with the IPEC licensing basis and the need to maintain the functionality of the hold down springs under all licensing basis conditions will be developed prior to the first required physical measurement. In accordance with SER Section 4.2.5, IPEC will submit this information to the NRC as part of the submittal to apply the approved version ofMRP-227.

SER Section 4.2.6, Applicant/Licensee Action Item 6 This action item does not apply to Westinghouse designed units.

SER Section 4.2.7, Applicant/Licensee Action Item 7 The IPEC plant specific analyses to demonstrate the lower support column bodies will maintain their functionality during the period of extended operation will consider the possible loss of fracture toughness in these components due to thermal and irradiation embrittlement. The analyses will be consistent with the IPEC licensing basis and the need to maintain the functionality of the lower support column bodies under all licensing basis conditions of operation. In accordance with SER Section 4.2.7, IPEC will submit this information to the NRC as part of the submittal to apply the approved version ofMRP-227.

SER Section 4.2.8, Applicant/Licensee Action Item 8 This document includes an inspection plan which addresses the identified plant-specific action items contained in the NRC Final Safety Evaluation for MRP-227. IPEC is not requesting any deviations from the guidance provided in MRP-227, as approved by the NRC.

EXAMINATION ACCEPTANCE AND EXPANSION CRITERIA 4.1 Examination Acceptance Criteria 4.1.1 Visual (VT-3) Examination Visual (VT -3) examination is an appropriate NDE method for the detection of general degradation conditions in many of the susceptible components. The ASME Code Section XI, Examination Category B-N-3, provides a set of relevant conditions for the visual (VT-3) examination of removable core support structures in Section IWB. These are:

1. structural distortion or displacement of parts to the extent that component function may be impaired;

2. loose, missing, cracked, or fractured parts, bolting, or fasteners;

3. corrosion or erosion that reduces the nominal section thickness by more than 5%;

4. wear of mating surfaces that may lead to loss of function; and

5. structural degradation of interior attachments such that the original cross-sectional area is reduced more than 5%.

For components in the Existing Programs group, these general relevant conditions are sufficient.

However, for components where visual (VT-3) is specified in the Primary or the Expansion group, more specific descriptions of the relevant conditions are provided in Table 5-5 for the benefit of the examiners. One or more of these specific relevant condition descriptions may be applicable to the Primary and Expansion components listed in Tables 5-2 and 5-3.

The examination acceptance criteria for components requiring visual (VT -3) examination is thus the absence of any of the relevant condition(s) specified in Table 5-5.

The disposition can include a supplementary examination to further characterize the relevant condition, an engineering evaluation to show that the component is capable of continued operation with a known relevant condition, or repair/replacement to remediate the relevant condition.

Page 23 OAGI0001350 00026

NL-11-107 Docket Nos. 50-247 and 50-286 Attachment 1 Indian Point Energy Center Reactor Vessel Internals Inspection Plan 4.1.2 Visual (VT-1) Examination Visual (VT -1) examination is defined in the ASME Code Section XI as an examination "conducted to detect discontinuities and imperfections on the surface of components, including such conditions as cracks, wear, corrosion, or erosion." The acceptance criterion for any visual (VT -1) examinations is the absence of any relevant conditions defined by the ASME Code, as supplemented by more specific plant inservice inspection requirements.

4.1.3 Enhanced Visual (EVT-1) Examination Enhanced visual (EVT -1) examination has the same requirements as the ASME Code Section XI visual (VT -1) examination, with additional requirements given in the Inspection Standard, MRP-228. These enhancements are intended to improve the detection and characterization of discontinuities taking into account the remote visual aspect of reactor internals examinations. As a result, EVT -1 examinations are capable of detecting small surface-breaking cracks and sizing surface crack length when used in conjunction with sizing aids (e.g. landmarks, ruler, and tape measure). EVT -1 examination is the appropriate NDE method for detection of cracking in plates or their welded joints. Thus the relevant condition applied for EVT -1 examination is the same as for cracking in Section XI which is crack-like surface-breaking indications.

Therefore, until such time as engineering studies provide a basis by which a quantitative amount of degradation can be shown acceptable for the specific component, any observed relevant condition must be dispositioned. In the interim, the examination acceptance criterion is the absence of any detectable surface-breaking indication.

4.1.4 Surface Examination Surface ET (eddy current testing) examination is specified as an alternative or as a supplement to visual examinations. No specific acceptance criteria for surface (ET) examination ofPWR internals locations are provided in the ASME Code Section XI. Since surface ET is employed as a signal-based examination, a technical justification per the Inspection Standard, MRP-228 provides the basis for detection and length sizing of surface-breaking or near-surface cracks. The signal-based relevant indication for surface (ET) is thus the same as the relevant condition for enhanced visual (EVT -1) examination. The acceptance criteria for enhanced visual (EVT -1) examinations in 4.1.3 (and accompanying entries in Table 5-5) are therefore applied when this method is used as an alternative or supplement to visual examination.

4.1.5 Volumetric Examination The intent of volumetric examinations specified for bolts and pins is to detect planar defects. No flaw sizing measurements are recorded or assumed in the acceptance or rejection of individual Page 24 OAGI0001350 00027

NL-11-107 Docket Nos. 50-247 and 50-286 Attachment 1 Indian Point Energy Center Reactor Vessel Internals Inspection Plan bolts or pins. Individual bolts or pins are accepted based on the absence of relevant indications established as part of the examination technical justification. When a relevant indication is detected in the cross-sectional area of the bolt or pin, it is assumed to be non-functional and the indication is recorded. A bolt or pin that passes the criterion of the examination is considered functional.

Because of this pass/fail acceptance of individual bolts or pins, the examination acceptance criterion for volumetric (UT) examination of bolts and pins is based on a reliable detection of indications as established by the individual technical justification for the proposed examination.

This is in keeping with current industry practice. For example, planar flaws on the order of30%

of the cross-sectional area have been determined reliably detectable in previous bolt NDE technical justifications for baffle-former bolting.

Bolted and pinned assemblies are evaluated for acceptance based on a plant specific evaluation.

4.2 Physical Measurements Examination Acceptance Criteria Continued functionality can be confirmed by physical measurements where, for example, loss of material caused by wear, loss of pre-load of clamping force caused by various degradation mechanisms, or distortion/deflection caused by void swelling may occur. For Westinghouse designs, tolerances are available on a design or plant-specific basis. Specific acceptance criteria will be developed as required, and thus are not provided generically in this plan.

4.3 Expansion Criteria The criterion for expanding the scope of examination from the Primary components to their linked Expansion components is contained in Table 5-5 for IPEe.
