Dear Sir / Madam:

On March 12, 2012, the Nuclear Regulatory Commission (NRC) issued a 50.54(f) letter to all power reactor licensees and holders of construction permits in active or deferred status.

NL-14-152 Docket Nos. 50-247 and 50-286 Page 2 of 2 of Reference 1 requested each addressee located in the Central and Eastern United States (CEUS) to submit a Seismic Hazard Evaluation and Screening Report within 1.5 years from the date of Reference 1.

In Reference 2, the Nuclear Energy Institute (NEI) requested NRC agreement to delay submittal of the final CEUS Seismic Hazard Evaluation and Screening Reports so that an update to the Electric Power Research Institute (EPRI) ground motion attenuation model could be completed and used to develop that information. NEI proposedthat descriptions of subsurface materials and properties and base case velocity profiles be submitted to the NRC by September 12, 2013, with the remaining seismic hazard and screening information submitted by March 31, 2014.

NRC agreed with that proposed path forward in Reference 3.

Reference 1 requested that licensees provide interim evaluations and actions taken or planned to address the higher seismic hazard relative to the design basis, as appropriate, prior to completion of the risk evaluation. In accordance with the NRC endorsed guidance in Reference 3, the attached Expedited Seismic Evaluation Process Report for Indian Point Units 2 and 3 provides the information described in Section 7 of Reference 4 in accordance with the schedule identified in Reference 2.

This letter contains regulatory commitments in the Attachment. If you have any questions regarding this report, please contact Mr. Robert Walpole, Manager, Regulatory Assurance at (914) 254-6710.

I declare under penalty of perjury that the foregoing is true and correct. Executed on December L42HAI)/,4 e /A l4?

or, Indian Point Unit 2 ESEP Report 1.0 PURPOSE AND OBJECTIVE Following the accident at the Fukushima Dai-ichi nuclear power plant resulting from the March 11, 2011, Great Tohoku Earthquake and subsequent tsunami, the Nuclear Regulatory Commission (NRC) established a Near-Term Task Force (NTTF) to conduct a systematic review of NRC processes and regulations and to determine if the agency should make additional improvements to its regulatory system. The NTTF developed a set of recommendations intended to clarify and strengthen the regulatory framework for protection against natural phenomena. Subsequently, the NRC issued a 50.54(f) letter on March 12, 2012 [1], requesting information to assure that these recommendations are addressed by all U.S. nuclear power plants. The 50.54(f) letter requests that licensees and holders of construction permits under 10 CFR Part 50 reevaluate the seismic hazards at their sites against present-day NRC requirements and guidance. Depending on the comparison between the reevaluated seismic hazard and the current design basis, further risk assessment may be required. Assessment approaches acceptable to the staff include a seismic probabilistic risk assessment (SPRA), or a seismic margin assessment (SMA). Based upon the assessment results, the NRC staff will determine whether additional regulatory actions are necessary.

This report describes the Expedited Seismic Evaluation Process (ESEP) undertaken for Indian Point Unit

2. The intent of the ESEP is to perform an interim action in response to the NRC's 50.54(f) letter to demonstrate seismic margin through a review of a subset of the plant equipment that can be relied upon to protect the reactor core following beyond design basis seismic events.

The ESEP is implemented using the methodologies in the NRC endorsed guidance in Electric Power Research Institute (EPRI) 3002000704, Seismic Evaluation Guidance: Augmented Approach for the Resolution of Fukushima Near-Term Task Force Recommendation 2.1: Seismic [2].

The objective of this report is to provide summary information describing the ESEP evaluations and results. The level of detail provided in the report is intended to enable the NRC to understand the inputs used, the evaluations performed, and the decisions made as a result of the interim evaluations.

2.0 BRIEF

SUMMARY

OF THE FLEX SEISMIC IMPLEMENTATION STRATEGIES The Indian Point Unit 2 FLEX strategies for Reactor Core Cooling and Heat Removal, Reactor Inventory Control/Long Term Subcriticality, and Containment Function are summarized below. This summary is derived from the Indian Point Energy Center Overall Integrated Plan (OIP) in Response to the March 12, 2012, Commission Order EA-12-049 [3], and is consistent with the second and third six-month status reports [4][5] and supplemented by supporting FLEX engineering calculations [6].

Core Cooling and Heat Removal The Phase 1 FLEX strategy at Indian Point Unit 2 for this function is to use Atmospheric Dump Valves (ADVs) and Main Steam Safety Valves (MSSVs) to remove heat, with the steam generator being fed by the turbine-driven Auxiliary Feedwater (AFW) pump. Backup nitrogen cylinders are available to support cycling the ADVs. Suction for the AFW pump is from the Condensate Storage Tank (CST), the Primary Water Storage Tank (PWST), and the Fire Water Storage Tank (FWST).

During Phase 2 of the FLEX strategy, portable diesel-driven pumps will be staged to provide makeup to the CST or to the steam generator feedwater pump suction. The diesel-driven steam generator FLEX feed pump will be staged to provide feedwater to steam generators when the turbine-driven AFW pump becomes unavailable. Diesel fuel for FLEX equipment will be provided from existing onsite Emergency Diesel Generator (EDG) Fuel Oil Storage Tanks.

Page 6

ni n5 Indian Point Unit 2 ESEP Report The key parameters to be monitored are: steam generator level, steam generator pressure, CST level, Reactor Coolant System (RCS) pressure, and RCS temperature.

RCS Inventory Control For At Power modes In Phase 1, plant cooldown and depressurization will occur. RCS Inventory control is achieved via the accumulators.

During Phase 2, to avoid adverse effects on the RCS natural circulation flow, the cold-leg accumulator isolation valves are electrically closed during the cooldown to prevent nitrogen injection into the RCS.

A FLEX pump will be used to provide RCS makeup with borated water supplied by the Refueling Water Storage Tank (RWST). To allow borated water injection into the RCS, the reactor head vent can be opened, if necessary, to provide a letdown path.

If an Extended Loss of AC Power (ELAP) event occurs during cold weather months when freezing of the RWST could possibly occur, a FLEX diesel generator can be used to repower the Electric Heat Trace (EHT) system.

For Shutdown modes In Phase 1, if the refueling canal is full then RCS makeup can be supplied by gravity feed from the RWST.

During Phase 2, a FLEX pump will be used to provide RCS makeup from the RWST in the same manner as for the At Power modes.

Additional key parameters to be monitored are pressurizer level, reactor vessel level, and nuclear instrumentation.

Containment Function Containment function is not expected to be challenged during Phase 1 or Phase 2 for an ELAP event occurring when the plant is in Mode 1-4. Therefore, no FLEX strategy beyond monitoring containment pressure and temperature was developed to support containment function.

Supporting Systems Necessary electrical components are outlined in the Indian Point Unit 2 0IP and primarily entail station batteries, Direct Current (DC) buses, distribution panels, inverters, battery chargers, and instrument buses.

3.0 EQUIPMENT SELECTION PROCESS AND ESEL The selection of equipment for the Expedited Seismic Equipment List (ESEL) followed the guidelines of EPRI 3002000704 [2]. The ESEL for Indian Point Unit 2 is presented in Attachment A. Information presented in Attachment A is drawn from the following references [3], [4], [5], [6], [7], [8], [9], [10],

c f " , J Indian Point Unit 2 ESEP Report 3.1 Equipment Selection Process and ESEL The selection of equipment to be included on the ESEL was based on installed plant equipment credited in the FLEX strategies during Phase 1, 2 and 3 mitigation of a Beyond Design Basis External Event (BDBEE), as outlined in the Indian Point Unit 2 0IP in Response to the March 12, 2012, Commission Order EA-12-049 [3], and is consistent with the second and third six-month status reports issued to the NRC [4] [5]. The OIP provides the Indian Point Unit 2 FLEX mitigation strategy and serves as the basis for equipment selected for the ESEP.

The scope of "installed plant equipment" includes equipment relied upon for the FLEX strategies to sustain the critical functions of core cooling and containment integrity consistent with the Indian Point Unit 2 0IP. FLEX recovery actions are excluded from the ESEP scope per EPRI 3002000704 [2]. The overall list of planned FLEX modifications and the scope for consideration herein is limited to those required to support core cooling, reactor coolant inventory and subcriticality, and containment integrity functions. Portable and pre-staged FLEX equipment (not permanently installed) are excluded from the ESEL per EPRI 3002000704.

The ESEL component selection followed the EPRI guidance outlined in Section 3.2 of EPRI 3002000704.

1. The scope of components is limited to that required to accomplish the core cooling and containment safety functions identified in Table 3-2 of EPRI 3002000704. The instrumentation monitoring requirements for core cooling/containment safety functions are limited to those outlined in the EPRI 3002000704 guidance, and are a subset of those outlined in the Indian Point Unit 2 0IP.
2. The scope of components is limited to installed plant equipment, and FLEX connections necessary to implement the Indian Point Unit 2 OIP as described in Section 2 of this report.
3. The scope of components assumes the credited FLEX connection modifications are implemented, and are limited to those required to support a single FLEX success path (i.e.,

either "Primary" or "Back-up/Alternate").

4. The "Primary" FLEX success path is to be specified. Selection of the "Back-up/Alternate" FLEX success path must be justified.
5. Phase 3 coping strategies are included in the ESEP scope, whereas recovery strategies are excluded.
6. Structures, systems, and components excluded per the EPRI 3002000704 guidance are:
  • Structures (e.g., containment, reactor building, control building, auxiliary building, etc.).
  • Piping, cabling, conduit, HVAC, and their supports.
  • Nuclear steam supply system components (e.g., RPV and internals, reactor coolant pumps and seals, etc.).
7. For cases in which neither train was specified as a primary or back-up strategy, then only one train component (generally 'A' train) is included in the ESEL.

'ioý- OnIv Indian Point Unit 2 ESEP Report 3.1.1 ESEL Development The ESEL was developed by reviewing the Indian Point OIP [3], second and third six-month status reports [4] [5], and supporting FLEX engineering calculations [6] to determine the major equipment involved in the FLEX strategies. Further reviews of plant drawings (e.g., Piping and Instrumentation Diagrams (P&IDs) and Electrical One Line Diagrams) were performed to identify the boundaries of the flowpaths to be used in the FLEX strategies and to identify specific components in the flowpaths needed to support implementation of the FLEX strategies. Boundaries were established at an electrical or mechanical isolation device (e.g., isolation amplifier, valve, etc.) in branch circuits / branch lines off the defined strategy electrical or fluid flowpath. P&IDs were the primary reference documents used to identify mechanical components and instrumentation. The flow paths used for FLEX strategies were selected and specific components were identified using detailed equipment and instrument drawings, piping isometrics, electrical schematics and one-line drawings, system descriptions, design basis documents, as necessary.

Cabinets and equipment controls containing relays, contactors, switches, potentiometers, circuit breakers and other electrical and instrumentation that could be affected by high-frequency earthquake motions and that impact the operation of equipment in the ESEL are required to be on the ESEL. These cabinets and components were identified in the ESEL.

For each parameter monitored during the FLEX implementation, a single indication was selected for inclusion in the ESEL. For each parameter indication, the components along the flow path from measurement to indication were included, since any failure along the path would lead to failure of that indication. Components such as flow elements were considered as part of the piping and were not included in the ESEL.

3.1.2 Power Operated Valves Page 3-3 of EPRI 3002000704 [2] notes that power operated valves not required to change state as part of the FLEX mitigation strategies are excluded from the ESEL. Page 3-2 also notes that functional failure modes of electrical and mechanical portions of the installed Phase 1 equipment should be considered (e.g. AFW trips). To address this concern, the following guidance is applied in the Indian Point Unit 2 ESEL for functional failure modes associated with power operated valves:

" Power operated valves not required to change state as part of the FLEX mitigation strategies were not included on the ESEL. The seismic event also causes the ELAP event; therefore, the valves are incapable of spurious operation as they would be de-energized.

  • Power operated valves not required to change state as part of the FLEX mitigation strategies during Phase 1, and are re-energized and operated during subsequent Phase 2 and 3 strategies, were not evaluated for spurious valve operation as the seismic event that caused the ELAP has passed before the valves are re-powered.

3.1.3 Pull Boxes Pull boxes were deemed unnecessary to be added to the ESEL as these components provide completely passive locations for pulling or installing cables. No breaks or connections in the cabling were included in pull boxes. Pull boxes were considered part of conduit and cabling, which were excluded in accordance with EPRI 3002000704 [2].

Page 9

Indian Point Unit 2 ESEP Report 3.1.4 Termination Cabinets Termination cabinets, including cabinets necessary for FLEX Phase 2 and Phase 3 connections, provide consolidated locations for permanently connecting multiple cables. The termination cabinets and the internal connections provide a completely passive function; however, the cabinets are included in the ESEL to ensure industry knowledge on panel/anchorage failure vulnerabilities is addressed.

3.1.5 Critical Instrumentation Indicators Critical indicators and recorders are typically physically located on panels/cabinets and are included as separate components; however, seismic evaluation of the instrument indication may be included in the panel/cabinet seismic evaluation (rule-of-the-box).

3.1.6 Phase 2 and 3 Piping Connections Item 2 in Section 3.1 above notes that the scope of equipment in the ESEL includes "... FLEX connections necessary to implement the Indian Point Unit 2 OIP as described in Section 2." Item 3 in Section 3.1 also notes that "The scope of components assumes the credited FLEX connection modifications are implemented, and are limited to those required to support a single FLEX success path (i.e., either "Primary" or "Back-up/Alternate")."

Item 6 in Section 3.1 above goes on to explain that "Piping, cabling, conduit, HVAC, and their supports" are excluded from the ESEL scope in accordance with EPRI 3002000704 [2].

Therefore, piping and pipe supports associated with FLEX Phase 2 and Phase 3 connections are excluded from the scope of the ESEP evaluation. However, any active valves in FLEX Phase 2 and Phase 3 connection flow path are included in the ESEL.

3.2 Justification for Use of Equipment That is Not the Primary Means for FLEX Implementation The Indian Point Unit 2 ESEL is based on the primary means of implementing the FLEX strategy.

Therefore, no additional justification is required.

4.0 GROUND MOTION RESPONSE SPECTRUM (GMRS) 4.1 Plot of GMRS Submitted by the Licensee In accordance with the guidance provided in Section 2.4.2 of the Screening, Prioritization and Implementation Details (SPID) [73] for rock sites, the SSE control point elevation is defined at the top of hard-rock and is applicable at grade in the free field as well as the various foundations elevations [74].

Table 4-2 shows these spectral acceleration values at selected frequencies for the 5% damped horizontal SSE.

Figure 4-2: GMRS to SSE Comparison for Indian Point Unit 2 The SSE envelops the GMRS for lower frequencies up to nearly 3Hz. The GMRS exceeds the SSE beyond that point. As the GMRS exceeds the SSE in the 1 to 1OHz range, the plant does not screen out of the ESEP according to Section 2.2 of EPRI 3002000704 [2]. The two special screening considerations as described in Section 2.2.1 of EPRI 3002000704, namely a) Low-frequency GMRS exceedances at Low Seismic Hazard Sites and b) Narrow Band Exceedances in the 1 to 10Hz range, provide criteria for accepting specific GMRS exceedances. However, the GMRS exceedances occur in the frequency range of interest and cannot be characterized as narrow-banded exceedances. Therefore, these special screening considerations do not apply for Indian Point Unit 2 and High Confidence of a Low Probability of Failure (HCLPF) evaluations are to be performed.

or In io 0 Indian Point Unit 2 ESEP Report 5.0 REVIEW LEVEL GROUND MOTION (RLGM) 5.1 Description of RLGM Selected The RLGM is selected based on Approach 1 in Section 4 of EPRI 3002000704 [2]. The RLGM is developed based on the SSE. The maximum GMRS/SSE ratio between 1 and 10Hz range occurs at 10Hz where the ratio is 0.648/0.168 = 3.86. As the maximum ratio of the GMRS to the SSE over the i to 10Hz range exceeds a value of 2, the GMRS/SSE ratio is set to the maximum scaling factor value of 2.0 for Indian Point Unit 2 in accordance with Section 4 of EPRI 3002000704. Table 5-1 lists the horizontal ground RLGM acceleration at 5% damping at selected frequencies and the plot is shown in Figure 5-1.

The RLGM is generated by plotting the digitized data on a log/linear graph paper, and connecting the points with straight lines.

Figure 5-1: RLGM for Indian Point Unit 2 5.2 Method to Estimate In-Structure Response Spectra (ISRS)

The RLGM ISRS for Indian Point Unit 2 are generated by scaling the SSE ISRS [76] [77]. The following steps are used to generate the RLGM ISRS.

1. Obtain the horizontal direction SSE ISRS for a particular damping value.
2. Calculate the horizontal RLGM ISRS by scaling the horizontal direction SSE ISRS by a factor of 2.0.
3. Repeat steps 1 and 2 to obtain RLGM ISRS for multiple damping values.

The vertical direction RLGM ISRS is obtained by scaling the vertical amplified ground response spectrum.

6.0 SEISMIC MARGIN EVALUATION APPROACH It is necessary to demonstrate that ESEL items have sufficient seismic capacity to meet or exceed the demand characterized by the RLGM. The seismic capacity is characterized as the PGA for which there is a HCLPF. The PGA is associated with a specific spectral shape, in this case the 5%-damped RLGM spectral shape. The HCLPF capacity must be equal to or greater than the RLGM PGA. The criteria for seismic capacity determination are given in Section 5 of EPRI 3002000704 [2].

There are two basic approaches for developing HCLPF capacities:

1. Deterministic approach using the conservative deterministic failure margin (CDFM) methodology of EPRI NP-6041-SL, A Methodology for Assessment of Nuclear Power Plant Seismic Margin (Revision 1) [78].

Page 16

Indian Point Unit 2 ESEP Report

2. Probabilistic approach using the fragility analysis methodology of EPRI TR-103959, Methodology for Developing Seismic Fragilities [79].

6.1 Summary of Methodologies Used Indian Point Unit 2 was classified as a 0.3g full scope plant in NUREG-1407 [80] and performed a SPRA as part of Individual Plant Examination for External Events (IPEEE) program. The SPRA is documented in [81]. Indian Point Unit 2 IPEEE program followed the NUREG-1407 methodology for seismic evaluation with plant seismic walkdowns using EPRI NP-6041-SL [78] and Generic Implementation Procedure [82]. Walkdown efforts were coordinated for evaluations pertaining to the IPEEE and Unresolved Safety Issue (USI) A-46. Section 3.3 of [75] established that the results of the Indian Point Unit 2 SPRA performed as part of IPEEE will not be used as a basis for Indian Point Unit 2 to screen-out of further risk assessment.

For ESEP, the SMA consisted of screening walkdowns and HCLPF calculations. The screening walkdowns used the screening tables from Chapter 2 of EPRI NP-6041-SL. The walkdowns were conducted by engineers trained in EPRI NP-6041-SL and were documented on Screening Evaluation Work Sheets (SEWS) from EPRI NP-6041-SL. Anchorage capacity calculations used the CDFM criteria from EPRI NP-6041-SL. Seismic demand was based on EPRI 3002000704 [2] using an RLGM of 2xSSE with a PGA of 0.3g as shown on Figure 5-1.

6.2 HCLPF Screening Process For ESEP, the components are screened at RLGM (2xSSE) with a 0.3g PGA. The screening tables in EPRI NP-6041-SL [781 are based on ground peak spectral accelerations of 0.8g and 1.2g. These both exceed the RLGM peak spectral acceleration.

The ESEL components were prescreened based on Table 2-4 of EPRI NP-6041-SL. Additional pre-screening, specifically for anchorage, considered walkdown results and documentation from NTTF 2.3 and SEWS from IPEEE and USI A-46. Equipment anchorage was screened out in cases where previous evaluations showed large available margin against SSE. The remaining components (i.e., components that do not screen out), were identified as requiring HCLPF calculations. ESEL components were walked down and based on the equipment and anchorage conditions, prescreening decisions were confirmed and a final list of required HCLPF calculations was generated. Equipment for which the screening caveats were met and for which the anchorage capacity exceeded the RLGM seismic demand are screened out from ESEP seismic capacity determination because the HCLPF capacity exceeds the RLGM.

The Indian Point Unit 2 ESEL contains 181 items. Of these, 30 are valves. In accordance with Table 2-4 of EPRI NP-6041-SL, both active and passive valves may be assigned a functional capacity of 0.8g peak spectral acceleration withoutany review other than looking for valves with large extended operators on small diameter piping, and anchorage is not a failure mode. Therefore, valves on the ESEL are screened out from ESEP seismic capacity determination, subject to the caveat regarding large extended operators on small diameter piping.

The non-valve components in the ESEL are screened based on the SMA results. If the SMA showed that the component met the EPRI NP-6041-SL screening caveats and the CDFM capacity exceeded the RLGM demand, the components are screened out from the ESEP capacity determination.

These block walls were assessed for potential seismic interaction impact resulting from the RLGM by reviewing the existing plant documents and/or by generating new analyses and found to be acceptable.

[2], which refers to EPRI NP-6041-SL [78] for the Seismic Margin Assessment process. Pages 2-26 through 2-30 of EPRI NP-6041-SL describe the seismic walkdown criteria, including the following key criteria.

"The SRT[Seismic Review Team] should "walk by" 100% of all components which are reasonably accessible and in non-radioactiveor low radioactiveenvironments. Seismic capability assessment of components which are inaccessible, in high-radioactiveenvironments, or possibly within contaminated containment, will have to rely more on alternatemeans such as photographicinspection, more reliance on seismic reanalysis,and possibly, smaller inspection teams and more hurriedinspections. A 100% "walk by" does not mean complete inspection of each component, nor does it mean requiringan electrician or other technician to de-energize and open cabinets or panelsfor detailed inspection of all components. This walkdown is not intended to be a QA or QC review or a review of the adequacy of the component at the SSE level.

If the SRT has a reasonable basisfor assuming that the group of components are similarand are similarly anchored,then it is only necessaryto inspect one component out of this group. The "similarity-basis"should be developed before the walkdown during the seismic capability preparatorywork (Step 3) by reference to drawings, calculationsor specifications. The one component or each type which is selected should be thoroughly inspected which probably does mean de-energizing and opening cabinets or panelsfor this very limited sample. Generally, a spare representativecomponent can be found so as to enable the inspection to be performed while the plant is in operation. At leastfor the one component of each type which is selected, anchorage should be thoroughly inspected.

The walkdown procedureshould be performed in an ad hoc manner. For each class of components the SRT should look closely at the first items and compare the field configurations with the construction drawings and/orspecifications. If a one-to-one correspondenceis found, then subsequent items do not have to be inspected in as great a detail. Ultimately the walkdown becomes a "walk by" of the component class as the SRT becomes confident that the constructionpattern is typical. This procedurefor inspection should be repeatedfor each component class; although, during the actual walkdown the SRT may be inspecting several classes of components in parallel. If serious exceptions to the drawings or questionable constructionpracticesarefound then the system or component class must be inspected in closer detail until the systematic deficiency is defined.

The 100% "walk by" is to look for outliers, lack of similarity,anchorage which is different from that shown on drawings or prescribedin criteriafor that component, potentialSI [Seismic Interaction]problems, situations that are at odds with the team members' past experience, and any other areas of serious seismic concern. If any such concerns surface, then the limited Page 18

'ju Indian Point Unit 2 ESEP Report sample size of one component of each type for thorough inspection will have to be increased.

The increase in sample size which should be inspected will depend upon the number of outliers and different anchorages,etc., which are observed. It is up to the SRT to ultimately select the sample size since they are the ones who are responsiblefor the seismic adequacy of all elements which they screen from the margin review. Appendix D gives guidancefor sampling selection."

6.3.2 Application of Previous Walkdown Information Several ESEL items were previously walked down during the Indian Point Unit 2 seismic IPEEE program, which was performed in accordance with USI A-46 evaluation program and NTTF Recommendation 2.3.

Those walkdown results were reviewed and the following steps were taken to confirm that the previous walkdown conclusions remained valid.

" A walk by was performed to confirm that the equipment material condition and configuration is consistent with the walkdown conclusions and that no new significant interactions related to block walls or piping attached to tanks exist.

  • If the ESEL item was screened out based on the previous walkdown, that screening evaluation was reviewed and reconfirmed for the ESEP.

6.3.3 Significant Walkdown Findings Consistent with the guidance from EPRI NP-6041-SL [78], no significant outliers or anchorage concerns were identified during the Indian Point Unit 2 seismic walkdowns. Based on walkdown results, HCLPF capacity evaluations were recommended for the following sixteen (16) components:

- r Indian Point Unit 2 ESEP Report Several block walls were identified in the proximity of ESEL equipment. These block walls were assessed for their structural adequacy to withstand the seismic loads resulting from the RLGM. For any cases where the block wall represented the HCLPF failure mode for an ESEL item, it is noted in the tabulated HCLPF values described in Section 6.6. One (1) HCLPF evaluation was performed addressing the block walls in close proximity to battery rooms 21, 22, and 24 as well as MCC-24A and MCC-29A.

  • Performing seismic capability walkdowns for equipment not included in previous seismic walkdowns (SQUG, IPEEE, or N1TF 2.3) to evaluate the equipment installed plant conditions
  • Performing screening evaluations using the screening tables in EPRI NP-6041-SL as described in

,Section 6.2

  • Performing HCLPF calculations considering various failure modes that include both structural failure modes (e.g. anchorage, load path etc.) and functional failure modes All HCLPF calculations were performed using the CDFM methodology. Eight (8) HCLPF calculations were performed to address the sixteen (16) components as well as the seismic adequacy of block walls.

6.6 Tabulated ESEL HCLPF Values (Including Key Failure Modes)

Tabulated ESEL HCLPF values are provided in Attachment B. The following notes apply to the information in the tables.

  • For items screened out using EPRI NP-6041-SL [78] screening tables, the HCLPF capacity is provided as >RLGM and the failure mode is listed as "Screened", (unless the controlling HCLPF value is governed by anchorage).
  • For items where anchorage controls the HCLPF value, the HCLPF value is listed in the table and the failure mode is noted as "anchorage." For the items where the component function controls the HCLPF value, the HCLPF value is listed in the table and the failure mode is noted as "functional."

After performing the HCLPF calculations, ESEL components were determined to have adequate capacity for the design basis loads and HCLPF greater than RLGM for all components except the following:

  • 0021RWST, 21 Refueling Water Storage Tank

" 300KFPT, Fire Water Storage Tank Modifications are planned for the above component.

8.0 ESEP CONCLUSIONS AND RESULTS 8.1 Supporting Information Indian Point Unit 2 has performed the ESEP as an interim action in response to the NRC's 50.54(f) letter

[1]. It was performed using the methodologies in the NRC endorsed guidance in EPRI 3002000704 [2].

The ESEP provides an important demonstration of seismic margin and expedites plant safety enhancements through evaluations and potential near-term modifications of plant equipment that can be relied upon to protect the reactor core following beyond design basis seismic events.

The ESEP is part of the overall Indian Point Unit 2 response to the NRC's 50.54(f) letter. On March 12, 2014, NEI submitted to the NRC results of a study [84] of seismic core damage risk estimates based on updated seismic hazard information as it applies to operating nuclear reactors in the Central and Eastern United States (CEUS). The study concluded that "site-specific seismic hazards show that there has not been an overall increase in seismic risk for the fleet of U.S. plants" based on the re-evaluated seismic hazards. As such, the "current seismic design of operating reactors continues to provide a safety margin to withstand potential earthquakes exceeding the seismic design basis."

The NRC's May 9, 2014 NTTF 2.1 Screening and Prioritization letter [83] concluded that the "fleet wide seismic risk estimates are consistent with the approach and results used in the GI-199 safety/risk assessment." The letter also stated that "As a result, the staff has confirmed that the conclusions reached in GI-199 safety/risk assessment remain valid and that the plants can continue to operate while additional evaluations are conducted."

Indian Point Unit 2 ESEP Report An assessment of the change in seismic risk for Indian Point Unit 2 was included in the fleet risk evaluation submitted in the March 12, 2014 NEI letter [84]; therefore, the conclusions in the NRC's May 9 letter also apply to Indian Point Unit 2.

In addition, the March 12, 2014 NEI letter provided an attached "Perspectives on the Seismic Capacity of Operating Plants," which (1) assessed a number of qualitative reasons why the design of Structures, Systems and Components (SSCs) inherently contain margin beyond their design level, (2) discussed industrial seismic experience databases of performance of industry facility components similar to nuclear SSCs, and (3) discussed earthquake experience at operating plants.

The fleet of currently operating nuclear power plants was designed using conservative practices, such that the plants have significant margin to withstand large ground motions safely. This has been borne out for those plants that have actually experienced significant earthquakes. The seismic design process has inherent (and intentional) conservatisms, which result in significant seismic margins within SSCs.

These conservatisms are reflected in several key aspects of the seismic design process, including:

" Safety factors applied in design calculations

  • Damping values used in dynamic analysis of SSCs
  • Bounding synthetic time histories for in-structure response spectra calculations
  • Broadening criteria for in-structure response spectra

" Response spectra enveloping criteria typically used in SSC analysis and testing applications

" Response spectra based frequency domain analysis rather than explicit time history based time domain analysis

  • Bounding requirements in codes and standards
  • Use of minimum strength requirements of structural components (concrete and steel)
  • Bounding testing requirements
  • Ductile behavior of the primary materials (that is, not crediting the additional capacity of materials such as steel and reinforced concrete beyond the essentially elastic range, etc.)

These design practices combine to result in margins such that the SSCs will continue to fulfill their functions at ground motions well above the SSE.

The intent of the ESEP is to perform an interim action in response to the NRC's 50.54(f) letter to demonstrate seismic margin through a review of a subset of the plant equipment that can be relied upon to protect the reactor core following beyond design basis seismic events. The RLGM used for the ESEP evaluation is a scaled version of the plant's SSE rather than the actual GMRS. To more fully characterize the risk impacts of the seismic ground motion represented by the GMRS on a plant specific basis, a more detailed seismic risk assessment (SPRA or risk-based SMA) is to be performed in accordance with EPRI 1025287 [73]. As identified in the Indian Point Unit 2 Seismic Hazard and GMRS submittal [75], Indian Point Unit 2 screens in for a risk evaluation. The complete risk evaluation will more completely characterize the probabilistic seismic ground motion input into the plant, the plant response to that probabilistic seismic ground motion input, and the resulting plant risk characterization. Indian Point Unit 2 will complete that evaluation in accordance with the schedule identified in NEI's letter dated April 9, 2013 [85] and endorsed by the NRC in their May 7, 2013 letter

[86].

Indian Point Unit 3 ESEP Report 1.0 PURPOSE AND OBJECTIVE Following the accident at the Fukushima Dai-ichi nuclear power plant resulting from the March 11, 2011, Great Tohoku Earthquake and subsequent tsunami, the Nuclear Regulatory Commission (NRC) established a Near-Term Task Force (NTTF) to conduct a systematic review of NRC processes and regulations and to determine if the agency should make additional improvements to its regulatory system. The NTTF developed a set of recommendations intended to clarify and strengthen the regulatory framework for protection against natural phenomena. Subsequently, the NRC issued a 50.54(f) letter on March 12, 2012 [1], requesting information to assure that these recommendations are addressed by all U.S. nuclear power plants. The 50.54(f) letter requests that licensees and holders of construction permits under 10 CFR Part 50 reevaluate the seismic hazards at their sites against present-day NRC requirements and guidance. Depending on the comparison between the reevaluated seismic hazard and the current design basis, further risk assessment may be required. Assessment approaches acceptable to the staff include a seismic probabilistic risk assessment (SPRA), or a seismic margin assessment (SMA). Based upon the assessment results, the NRC staff will determine whether additional regulatory actions are necessary.

This report describes the Expedited Seismic Evaluation Process (ESEP) undertaken for Indian Point Unit

3. The intent of the ESEP is to perform an interim action in response to the NRC's 50.54(f) letter to demonstrate seismic margin through a review of a subset of the plant equipment that can be relied upon to protect the reactor core following beyond design basis seismic events.

The ESEP is implemented using the methodologies in the NRC endorsed guidance in Electric Power Research Institute (EPRI) 3002000704, Seismic Evaluation Guidance: Augmented Approach for the Resolution of Fukushima Near-Term Task Force Recommendation 2.1: Seismic [2].

The objective of this report is to provide summary information describing the ESEP evaluations and results. The level of detail provided in the report is intended to enable the NRC to understand the inputs used, the evaluations performed, and the decisions made as a result of the interim evaluations.

2.0 BRIEF

SUMMARY

OF THE FLEX SEISMIC IMPLEMENTATION STRATEGIES The Indian Point Unit 3 FLEX strategies for Reactor Core Cooling and Heat Removal, Reactor Inventory Control/Long Term Subcriticality, and Containment Function are summarized below. This summary is derived from the Indian Point Energy Center Overall Integrated Plan (OIP) in Response to the March 12, 2012, Commission Order EA-12-049 [3], and is consistent with the second and third six-month status reports [4][5] and supplemented by supporting FLEX engineering calculations [6].

Core Cooling and Heat Removal The Phase 1 FLEX strategy at Indian Point Unit 3 for this function is to use Atmospheric Dump Valves (ADVs) and Main Steam Safety Valves (MSSVs) to remove heat, with the steam generator being fed by the turbine-driven Auxiliary Feedwater (AFW) pump. Suction for the AFW pump is from the Condensate Storage Tank (CST). Backup nitrogen cylinders are available to support cycling the ADVs.

During Phase 2 of the FLEX strategy, portable diesel-driven pumps will be staged to provide makeup to the CST or to the steam generator feedwater pump suction. The diesel-driven steam generator FLEX feed pump will be staged to provide feedwater to steam generators in the event that the turbine-driven AFW pump becomes unavailable. The Primary Water Storage Tank (PWST) or Fire Water Storage Tanks (FWSTs) will be used as makeup sources to the CST. Diesel fuel for FLEX equipment can be provided from existing onsite Emergency Diesel Generator (EDG) Fuel Oil Storage Tanks.

Page 6

I nl Indian Point Unit 3 ESEP Report The key parameters to be monitored are: steam generator level, steam generator pressure, CST level, Reactor Coolant System (RCS) pressure, and RCS temperature.

RCS Inventory Control ForAt Power modes In Phase 1, plant cooldown and depressurization will occur. Inventory control is achieved via the accumulators.

During Phase 2, to avoid adverse effects on the RCS natural circulation flow, the cold-leg accumulator isolation valves are electrically closed during the cooldown to prevent nitrogen injection into the RCS.

A FLEX pump will be used to provide RCS makeup with borated water supplied by the Refueling Water Storage Tank (RWST). To allow borated water injection into the RCS, the reactor head vent can be opened, if necessary, to provide a letdown path.

If the Extended Loss of AC Power (ELAP) event occurs during cold weather months when freezing of the RWST could possibly occur, a FLEX diesel generator can be used to repower the Electric Heat Trace (EHT) system.

ForShutdown modes In Phase 1, if the refueling canal is full, RCS makeup will be supplied by gravity feed from the RWST.

During Phase 2, a FLEX pump will be used to provide RCS makeup from the RWST in the same manner as for the At Power modes.

Additional key parameters to be monitored are pressurizer level and reactor vessel level and nuclear instrumentation.

Containment Function Containment function is not expected to be challenged during Phase 1 or Phase 2 for an ELAP event occurring when the plant is in Mode 1-4. Therefore, no FLEX strategy beyond monitoring containment pressure and temperature was developed to support containment function.

For Modes 5 and 6, containment pressure could be challenged unless a vent path is established.

Methods to establish a vent path will be used and include: opening penetration UU, which is used during outages as an additional air supply, deflating the sealing ring of the equipment hatch (if installed), or another vent path identified and evaluated.

Supporting Systems Necessary electrical components are outlined in the Indian Point Unit 3 QIP and primarily entail station batteries, Direct Current (DC) buses, distribution panels, inverters, battery chargers, and instrument buses.

3.0 EQUIPMENT SELECTION PROCESS AND ESEL The selection of equipment for the Expedited Seismic Equipment List (ESEL) followed the guidelines of EPRI 3002000704 [2]. The ESEL for Indian Point Unit 3 is presented in Attachment A. Information presented in Attachment A is drawn from the following references [3], [4], [5], [6], [7], [8], [9], [10],

[11], [12], [13], [14], [15], [16], [17], [18], [19], [20], [21], [22], [23], [24], [25], [26], [27], [28], [29], [30],

Indian Point Unit 3 ESEP Report 3.1 Equipment Selection Process and ESEL The selection of equipment to be included on the ESEL was based on installed plant equipment credited in the FLEX strategies during Phase 1, 2 and 3 mitigation of a Beyond Design Basis External Event (BDBEE), as outlined in the Indian Point Unit 3 OIP in Response to the March 12, 2012, Commission Order EA-12-049 [3] and is consistent with the second and third six-month status report issued to the NRC [4][5]. The OIP provides the Indian Point Unit 3 FLEX mitigation strategy and serves as the basis for equipment selected for the ESEP.

The scope of "installed plant equipment" includes equipment relied upon for the FLEX strategies to sustain the critical functions of core cooling and containment integrity consistent with the Indian Point Unit 3 0IP. FLEX recovery actions are excluded from the ESEP scope per EPRI 3002000704 [2]. The overall list of planned FLEX modifications and the scope for consideration herein is limited to those required to support core cooling, reactor coolant inventory and subcriticality, and containment integrity functions. Portable and pre-staged FLEX equipment (not permanently installed) are excluded from the ESEL per EPRI 3002000704.

The ESEL component selection followed the EPRI guidance outlined in Section 3.2 of EPRI 3002000704.

1. The scope of components is limited to that required to accomplish the core cooling and containment safety functions identified in Table 3-2 of EPRI 3002000704. The instrumentation monitoring requirements for core cooling/containment safety functions are limited to those outlined in the EPRI 3002000704 guidance, and are a subset of those outlined in the Indian Point Unit 3 0IP.
2. The scope of components is limited to installed plant equipment, and FLEX connections necessary to implement the Indian Point Unit 3 OIP as described in Section 2 of this report.
3. The scope of components assumes the credited FLEX connection modifications are implemented, and are limited to those required to support a single FLEX success path (i.e.,

either "Primary" or "Back-up/Alternate").

4. The "Primary" FLEX success path is to be specified. Selection of the "Back-up/Alternate" FLEX success path must be justified.
5. Phase 3 coping strategies are included in the ESEP scope, whereas recovery strategies are excluded.
6. Structures, systems, and components excluded per the EPRI 3002000704 [2] guidance are:
  • Structures (e.g. containment, reactor building, control building, auxiliary building, etc.).
  • Piping, cabling, conduit, HVAC, and their supports.
  • Manual valves and rupture disks.
  • Nuclear steam supply system components (e.g. RPV and internals, reactor coolant pumps and seals, etc.).
7. For cases in which neither train was specified as a primary or back-up strategy, then only one train component (generally 'A' train) is included in the ESEL.

Indian Point Unit 3 ESEP Report 3.1.1 ESEL Development The ESEL was developed by reviewing the Indian Point OIP [3], second and third six-month status reports [4][5] to determine the major equipment involved in the FLEX strategies. Further reviews of plant drawings (e.g., Piping and Instrumentation Diagrams (P&IDs) and Electrical One Line Diagrams) were performed to identify the boundaries of the flow paths to be used in the FLEX strategies and to identify specific components in the flow paths needed to support implementation of the FLEX strategies. Boundaries were established at an electrical or mechanical isolation device (e.g., isolation amplifier, valve, etc.) in branch circuits / branch lines off the defined strategy electrical or fluid flow path. P&IDs were the primary reference documents used to identify mechanical components and instrumentation. The flow paths used for FLEX strategies were selected and specific components were identified using detailed equipment and instrument drawings, piping isometrics, electrical schematics and one-line drawings, system descriptions, design basis documents, as necessary.

Cabinets and equipment controls containing relays, contactors, switches, potentiometers, circuit breakers and other electrical and instrumentation that could be affected by high-frequency earthquake motions and that impact the operation of equipment in the ESEL are required to be on the ESEL. These cabinets and components were identified in the ESEL.

For each parameter monitored during the FLEX implementation, a single indication was selected for inclusion in the ESEL. For each parameter indication, the components along the flow path from measurement to indication were included, since any failure along the path would lead to failure of that indication. Components such as flow elements were considered as part of the piping and were not included in the ESEL.

3.1.2 Power Operated Valves Page 3-3 of EPRI 3002000704 [2] notes that power operated valves not required to change state as part of the FLEX mitigation strategies are excluded from the ESEL. Page 3-2 also notes that "functional failure modes of electrical and mechanical portions of the installed Phase 1 equipment should be considered (e.g. AFW trips)." To address this concern, the following guidance is applied in the Indian Point Unit 3 ESEL for functional failure modes associated with power operated valves:

" Power operated valves not required to change state as part of the FLEX mitigation strategies were not included on the ESEL. The seismic event also causes the ELAP event; therefore, the valves are incapable of spurious operation as they would be de-energized.

" Power operated valves not required to change state as part of the FLEX mitigation strategies during Phase 1, and are re-energized and operated during subsequent Phase 2 and 3 strategies, were not evaluated for spurious valve operation as the seismic event that caused the ELAP has passed before the valves are re-powered.

Page 9

Indian Point Unit 3 ESEP Report 3.1.3 Pull Boxes Pull boxes were deemed unnecessary to be added to the ESEL as these components provide completely passive locations for pulling or installing cables. No breaks or connections in the cabling were included in pull boxes. Pull boxes were considered part of conduit and cabling, which were excluded in accordance with EPRI 3002000704 [2].

3.1.4 Termination Cabinets Termination cabinets, including cabinets necessary for FLEX Phase 2 and Phase 3 connections, provide consolidated locations for permanently connecting multiple cables. The termination cabinets and the internal connections provide a completely passive function; however, the cabinets are included in the ESEL to ensure industry knowledge on panel/anchorage failure vulnerabilities is addressed.

3.1.5 Critical Instrumentation Indicators Critical indicators and recorders are typically physically located on panels/cabinets and are included as separate components; however, seismic evaluation of the instrument indication may be included in the panel/cabinet seismic evaluation (rule-of-the-box).

3.1.6 Phase 2 and 3 Piping Connections Item 2 in Section 3.1 above notes that the scope of equipment in the ESEL includes "... FLEX connections necessary to implement the Indian Point Unit 3 0IP as described in Section 2." Item 3 in Section 3.1 also notes that "The scope of components assumes the credited FLEX connection modifications are implemented, and are limited to those required to support a single FLEX success path (i.e., either "Primary" or "Back-up/Alternate")."

Item 6 in Section 3.1 above goes on to explain that "Piping, cabling, conduit, HVAC, and their supports" are excluded from the ESEL scope in accordance with EPRI 3002000704 [2].

Therefore, piping and pipe supports associated with FLEX Phase 2 and Phase 3 connections are excluded from the scope of the ESEP evaluation. However, any active valves in FLEX Phase 2 and Phase 3 connection flow path are included in the ESEL.

3.2 Justification for Use of Equipment That is Not the Primary Means for FLEX Implementation No equipment that was not part of the primary success path was selected for the Indian Point Unit 3 ESEL.

Figure 4-2: GMRS to SSE Comparison for Indian Point Unit 3 The SSE envelops the GMRS for lower frequencies up to nearly 3 Hz. The GMRS exceeds the SSE beyond that point. As the GMRS exceeds the SSE in the 1 to 10 Hz range, the plant does not screen out of the ESEP according to Section 2.2 of EPRI 3002000704 [2]. The two special screening considerations as described in Section 2.2.1 of EPRI 3002000704, namely a) Low-frequency GMRS exceedances at Low Seismic Hazard Sites and b) Narrow Band Exceedances in the 1 to 1OHz range, provide criteria for accepting specific GMRS exceedances. However, the GMRS exceedances occur in the frequency range of interest and cannot be characterized as narrow-band exceedances. Therefore, these special screening considerations do not apply for Indian Point Unit 3 and High Confidence of a Low Probability of Failure (HCLPF) evaluations are to be performed.

Indian Point Unit 3 ESEP Report 5.0 REVIEW LEVEL GROUND MOTION (RLGM) 5.1 Description of RLGIvM Selected The RLGM is selected based on Approach 1 in Section 4 of EPRI 3002000704 [2]. The RLGM is developed based on the SSE. The maximum GMRS/SSE ratio between I and 10 Hz range occurs at 10 Hz where the ratio is 0.648/0.168 = 3.86. As the maximum ratio of the GMRS to the SSE over the 1 to 10 Hz range exceeds a value of 2, the GMRS/SSE ratio is set to the maximum scaling factor value of 2.0 for IP3 in accordance with Section 4 of EPRI 3002000704. Table 5-1 lists the horizontal ground RLGM acceleration at 5% damping at selected frequencies and the plot is shown in Figure 5-1. The RLGM is generated by plotting the digitized data on a log/linear graph paper, and connecting the points with straight lines.

Figure 5-1: RLGM for Indian Point Unit 3 5.2 Method to Estimate In-Structure Response Spectra (ISRS)

The RLGM ISRS for Indian Point Unit 3 are generated by scaling the SSE ISRS [70]. The following steps are used to generate the RLGM ISRS.

1. Obtain the horizontal direction SSE ISRS for a particular damping value.
2. Calculate the horizontal RLGM ISRS by scaling the horizontal direction SSE ISRS by a factor of 2.0.
3. Repeat steps 1 and 2 to obtain RLGM ISRS for multiple damping values.

The vertical direction RLGM ISRS is obtained by scaling the vertical amplified ground response spectrum.

6.0 SEISMIC MARGIN EVALUATION APPROACH It is necessary to demonstrate that ESEL items have sufficient seismic capacity to meet or exceed the demand characterized by the RLGM. The seismic capacity is characterized as the PGA for which there is a HCLPF. The PGA is associated with a specific spectral shape, in this case the 5%-damped RLGM spectral shape. The HCLPF capacity must be equal to or greater than the RLGM PGA. The criteria for seismic capacity determination are given in Section 5 of EPRI 3002000704 [2].

There are two basic approaches for developing HCLPF capacities:

1. Deterministic approach using the conservative deterministic failure margin (CDFM) methodology of EPRI NP-6041-SL, A Methodology for Assessment of Nuclear Power Plant Seismic Margin (Revision 1) [71].

Indian Point Unit 3 ESEP Report

2. Probabilistic approach using the fragility analysis methodology of EPRI TR-103959, Methodology for Developing Seismic Fragilities [72].

6.1 Summary of Methodologies Used Indian Point Unit 3 was classified as a 0.3g full scope plant in NUREG-1407 [73] and performed a SPRA as part of Individual Plant Examination for External Events (IPEEE) program. The SPRA is documented in [48]. Indian Point Unit 3 IPEEE program followed the NUREG-1407 methodology for seismic evaluation with plant seismic walkdowns using the EPRI NP-6041-SL [71] and Generic Implementation Procedure [74]. Walkdown efforts were coordinated for evaluations pertaining to the IPEEE and Unresolved Safety Issue (USI) A-46. Section 3.3 and Appendix B of [69] established that in accordance with the criteria established in SPID [68] Section 3.3, the IPEEE and reassessment of IHS are adequate to support screening of the updated seismic hazard for Indian Point Unit 3. Hence, the risk insights obtained from the IPEEE are used to assess risk for ESEP where applicable.

For ESEP, the evaluation consisted of screening walkdowns and HCLPF calculations. The screening walkdowns used the screening tables from Chapter 2 of EPRI NP-6041-SL. The walkdowns were conducted by engineers trained in EPRI NP-6041-SL and were documented on Screening Evaluation Work Sheets (SEWS) from EPRI NP-6041-SL. Anchorage capacity calculations used the CDFM criteria from EPRI NP-6041-SL. Seismic demand was based on EPRI 3002000704 [2] using an RLGM of 2xSSE with a PGA of 0.3g PGA as shown on Figure 5-1.

6.2 HCLPF Screening Process For ESEP, the components are screened considering RLGM (2xSSE) with a 0.3g PGA. The screening tables in EPRI NP-6041-SL [71] are based on ground peak spectral accelerations of 0.8g and 1.2g. These both exceed the RLGM peak spectral acceleration.

The ESEL components were prescreened based on Table 2-4 of EPRI NP-6041-SL. Additional pre-screening, specifically for anchorage, considered walkdown results and documentation from NTTF 2.3 and SEWS from IPEEE and USI A-46. Equipment anchorage was screened out in cases where previous evaluations showed large available margin against SSE. The remaining components (i.e., components that do not screen out), were identified as requiring HCLPF calculations. ESEL components were walked down and based on the equipment and anchorage conditions, prescreening decisions were confirmed and a final list of required HCLPF calculations was generated. Equipment for which the screening caveats were met and for which the anchorage capacity exceeded the RLGM seismic demand are screened out from ESEP seismic capacity determination because the HCLPF capacity exceeds the RLGM.

The Indian Point Unit 3 ESEL contains 194 items. Of these, 30 are valves. In accordance with Table 2-4 of EPRI NP-6041-SL, valves may be assigned a functional capacity of 0.8g peak spectral acceleration without any review other than looking for valves with large extended operators on small diameter piping, and anchorage is not a failure mode. Therefore, valves on the ESEL are screened out from ESEP seismic capacity determination, subject to the caveat regarding large extended operators on small diameter piping.

Page 17

Indian Point Unit 3 ESEP Report 6.3 Seismic Walkdown Approach 6.3.1 Walkdown Approach Walkdowns were performed in accordance with the criteria provided in Section 5 of EPRI 3002000704

[2], which refers to EPRI NP-6041-SL [71] for the Seismic Margin Assessment process. Pages 2-26 through 2-30 of EPRI NP-6041-SL describe the seismic walkdown criteria, including the following key criteria.

"The SRT [Seismic Review Team] should "walk by" 100% of all components which are reasonably accessible and in non-radioactiveor low radioactiveenvironments. Seismic capability assessment of components which are inaccessible, in high-radioactiveenvironments, or possibly within contaminatedcontainment,will have to rely more on alternatemeans such as photographicinspection, more reliance on seismic reanalysis, and possibly, smaller inspection teams and more hurried inspections. A 100% "walk by" does not mean complete inspection of each component, nor does it mean requiringan electrician or other technician to de-energize and open cabinets or panelsfor detailed inspection of all components. This walkdown is not intended to be a QA or QC review or a review of the adequacy of the component at the SSE level.

If the SRT has a reasonable basisfor assuming that the group of components are similar and are similarly anchored, then it is only necessaryto inspect one component out of this group. The "similarity-basis"should be developed before the walkdown during the seismic capability preparatorywork (Step 3) by reference to drawings, calculationsor specifications. The one component or each type which is selected should be thoroughly inspected which probably does mean de-energizing and opening cabinets or panels for this very limited sample. Generally,a spare representativecomponent can be found so as to enable the inspection to be performed while the plant is in operation. At leastfor the one component of each type which is selected, anchorageshould be thoroughly inspected.

The walkdown procedureshould be performed in an ad hoc manner. For each class of components the SRT should look closely at the first items and compare the field configurations with the constructiondrawings and/or specifications. If a one-to-one correspondenceis found, then subsequent items do not have to be inspected in as great a detail. Ultimately the walkdown becomes a "walk by" of the component class as the SRT becomes confident that the constructionpattern is typical. This procedurefor inspection should be repeatedfor each component class; although, during the actual walkdown the SRT may be inspecting several classes of components in parallel. If serious exceptions to the drawings or questionable constructionpracticesare found then the system or component class must be inspected in closer detail until the systematic deficiency is defined.

The 100% "walk by" is to look for outliers, lack of similarity,anchorage which is differentfrom that shown on drawings or prescribedin criteriafor that component, potential SI [Seismic Interaction]problems, situations that are at odds with the team members' past experience, and any other areas of serious seismic concern. If any such concerns surface, then the limited sample size of one component of each type for thorough inspection will have to be increased.

The increasein sample size which should be inspected will depend upon the number of outliers and different anchorages,etc., which are observed. It is up to the SRT to ultimately select the sample size since they are the ones who are responsiblefor the seismic adequacyof all elements which they screen from the margin review. Appendix D gives guidancefor sampling selection."

I Indian Point Unit 3 ESEP Report 6.3.2 Application of Previous Walkdown Information Several ESEL items were previously walked down during the Indian Point Unit 3 seismic IPEEE program, for seismic IPEEE outlier resolutions in accordance with USI A-46 evaluation program and NTTF Recommendation 2.3. Those walkdown results were reviewed and the following steps were taken to confirm that the previous walkdown conclusions remained valid.

" A walk by was performed to confirm that the equipment material condition and configuration is consistent with the walkdown conclusions and that no new significant interactions related to block walls or piping attached to tanks exist.

  • If the ESEL item was screened out based on the previous walkdown, that screening evaluation was reviewed and reconfirmed for the ESEP.

6.3.3 Significant Walkdown Findings Consistent with the guidance from EPRI NP-6041-SL [71], no significant outliers or anchorage concerns were identified during the Indian Point Unit 3 seismic walkdowns. Based on walkdown results, HCLPF capacity evaluations were recommended for the following thirteen (13) components:

  • Performing HCLPF calculations considering various failure modes that include both structural failure modes (e.g. anchorage, load path etc.) and functional failure modes All HCLPF calculations were performed using the CDFM methodology. A total of six (6) HCLPF calculations were performed to address the thirteen (13) components.
  • Calculation "Battery Chargers 31, 32, & 34" addressing three (3) components BATT CHGR 31, BATT CHGR 32 and BATT CHGR 34

6.6 Tabulated ESEL HCLPF Values (Including Key Failure Modes)

Tabulated ESEL HCLPF values are provided in Attachment B. The following notes apply to the information in the tables.

  • For items screened out using EPRI NP-6041-SL [71] screening tables, the HCLPF capacity is provided as >RLGM and the failure mode is listed as "Screened", (unless the controlling HCLPF value is governed by anchorage).
  • For items where anchorage controls the HCLPF value, the HCLPF value is listed in the table and the failure mode is noted as "anchorage." For the items where the component function controls the HCLPF value, the HCLPF value is listed in the table and the failure mode is noted as "functional."

After performing the HCLPF calculations, the evaluated ESEL components were determined to have adequate capacity for the design basis loads and HCLPF greater than RLGM.

8.0 ESEP CONCLUSIONS AND RESULTS 8.1 Supporting Information Indian Point Unit 3 has performed the ESEP as an interim action in response to the NRC's 50.54(f) letter

[1]. It was performed using the methodologies in the NRC endorsed guidance in EPRI 3002000704 [2].

The ESEP provides an important demonstration of seismic margin and expedites plant safety enhancements through evaluations and potential near-term modifications of plant equipment that can be relied upon to protect the reactor core following beyond design basis seismic events.

The ESEP is part of the overall Indian Point Unit 3 response to the NRC's 50.54(f) letter. On March 12, 2014, NEI submitted to the NRC results of a study [76] of seismic core damage risk estimates based on updated seismic hazard information as it applies to operating nuclear reactors in the Central and Eastern United States (CEUS). The study concluded that "site-specific seismic hazards show that there has not been an overall increase in seismic risk for the fleet of U.S. plants" based on the re-evaluated seismic hazards [69]. As such, the "current seismic design of operating reactors continues to provide a safety margin to withstand potential earthquakes exceeding the seismic design basis."

The NRC's May 9, 2014 NTTF 2.1 Screening and Prioritization letter [75] concluded that the "fleet wide seismic risk estimates are consistent with the approach and results used in the GI-199 safety/risk assessment." The letter also stated that "As a result, the staff has confirmed that the conclusions Page 22

Indian Point Unit 3 ESEP Report reached in GI-199 safety/risk assessment remain valid and that the plants can continue to operate while additional evaluations are conducted."

An assessment of the change in seismic risk for Indian Point Unit 3 was included in the fleet risk evaluation submitted in the March 12, 2014 NEI letter [76]; therefore, the conclusions in the NRC's May 9 letter also apply to Indian Point Unit 3.

In addition, the March 12, 2014 NEI letter provided an attached "Perspectives on the Seismic Capacity of Operating Plants," which (1) assessed a number of qualitative reasons why the design of Structures, Systems and Components (SSCs) inherently contain margin beyond their design level, (2) discussed industrial seismic experience databases of performance of industry facility components similar to nuclear SSCs, and (3) discussed earthquake experience at operating plants.

The fleet of currently operating nuclear power plants was designed using conservative practices, such that the plants have significant margin to withstand large ground motions safely. This has been borne out for those plants that have actually experienced significant earthquakes. The seismic design process has inherent (and intentional) conservatisms which result in significant seismic margins within SSCs.

These conservatisms are reflected in several key aspects of the seismic design process, including:

  • Safety factors applied in design calculations
  • Damping values used in dynamic analysis of SSCs
  • Bounding synthetic time histories for in-structure response spectra calculations
  • Broadening criteria for in-structure response spectra

" Response spectra enveloping criteria typically used in SSC analysis and testing applications

  • Response spectra based frequency domain analysis rather than explicit time history based time domain analysis
  • Bounding requirements in codes and standards
  • Use of minimum strength requirements of structural components (concrete and steel)
  • Bounding testing requirements
  • Ductile behavior of the primary materials (that is, not crediting the additional capacity of materials such as steel and reinforced concrete beyond the essentially elastic range, etc.)

These design practices combine to result in margins such that the SSCs will continue to fulfill their functions at ground motions well above the SSE.

The intent of the ESEP is to perform an interim action in response to the NRC's 50.54(f) letter to demonstrate seismic margin through a review of a subset of the plant equipment that can be relied upon to protect the reactor core following beyond design basis seismic events. The RLGM used for the ESEP evaluation is a scaled version of the plant's SSE rather than the actual GMRS. To more fully characterize the risk impacts of the seismic ground motion represented by the GMRS on a plant specific basis, a more detailed seismic risk assessment (SPRA or risk-based SMA) is to be performed in accordance with EPRI 1025287 [68]. As identified in the Indian Point Unit 3 Seismic Hazard and GMRS submittal [69], Indian Point Unit 3 screens in for a risk evaluation. The complete risk evaluation will more completely characterize the probabilistic seismic ground motion input into the plant, the plant response to that probabilistic seismic ground motion input, and the resulting plant risk Page 23

Indian Point Unit 3 ESEP Report characterization. Indian Point Unit 3 will complete that evaluation in accordance with the schedule identified in NEI's letter dated April 9, 2013 [77] and endorsed by the NRC in their May 7, 2013 letter

[78].

8.2 Identification of Planned Modifications Insights from the ESEP identified the following items where the HCLPF is below the RLGM and plant modifications will be made in accordance with EPRI 3002000704 [2] to enhance the seismic capacity of the plant. Subject modifications are planned to provide additional seismic margin such that the HCLPF will exceed the RLGM.

  • FP-T-2, 32 Fire Water Storage Tank 8.3 Modification Implementation Schedule Plant modifications described in Section 8.2 will be performed in accordance with the schedule identified in NEI letter dated April 9, 2013 [77], which states that plant modifications not requiring a planned refueling outage will be completed by December 2016 and modifications requiring a refueling outage will be completed within two planned refueling outages after December 31, 2014.
