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 James A. FitzPatrick. 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 James A. FitzPatrick 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 James A. FitzPatrick Overall Integrated Plan (OIP) in Response to the March 12, 2012, Commission Order EA 049 [3] and is consistent with the third six-month Status Report
[4]. As the ESEP is an interim action to assess available seismic margin against beyond design basis events, equipment selection and the corresponding seismic evaluations are based on FLEX strategies at the time of initial ESEP report submittal to the NRC. Consequently, updates to FLEX strategy after initial ESEP submittal, and changes to supporting plant documentation, are not captured within this report.
Core cooling and inventory control are achieved during the first five (5) hours using the Reactor Core Isolation Cooling (RCIC) system initially aligned to take suction from the Condensate Storage Tank (CST), with the suction swapped to the torus when the operators determine the event is a Beyond Design Basis External Event (BDBEE). Pressure control and heat removal are accomplished by Safety Relief Valves (SRVs) venting to the torus. At approximately five (5) hours, suction will be swapped back to the CST for torus temperature control and a controlled depressurization is commenced using RCIC and cycling the SRVs.
Page 6 James A. FitzPatrick ESEP Report At about ten (10) hours (beginning of Phase 2), the operators will need to connect and run a portable 200 kW FLEX diesel generator to the Class 1E 600 VAC electrical buses to re
-power the battery chargers to maintain DC control power. At 23 hours2.662037e-4 days <br />0.00639 hours <br />3.80291e-5 weeks <br />8.7515e-6 months <br />, the torus will be vented via the hardened containment vent to maintain containment parameters within acceptable limits and within the limits that support continued use of the RCIC system. The torus and CST will enable the RCIC to provide make
-up for at least 35 hours4.050926e-4 days <br />0.00972 hours <br />5.787037e-5 weeks <br />1.33175e-5 months <br /> without replacement. Prior to depletion of the CST, James A. FitzPatrick will establish the flow path from the seismically
-qualified diesel
-driven fire pump 76P
-1 to provide makeup directly to the reactor pressure vessel. For Phase 3, the reactor core cooling strategy is to place one loop of RHR into the shutdown cooling mode. This will be accomplished by powering an RHR pump from either Class 1E emergency bus 10500 or Class 1E emergency bus 10600 utilizing the 4160 VAC FLEX portable diesel generator. A modification will be implemented to provide a cross
-connection between the fire protection system and one train of the RHR service water system. The seismically qualified diesel
-driven fire pump (76P
-1) will be used to provide lake water to RHR service water side of the appropriate RHR heat exchanger.
Necessary electrical components are outlined in the James A. FitzPatrick FLEX OIP submittal, and primarily entail 125 VDC power buses, motor control centers, vital batteries, battery chargers, 600 VAC buses, and 4160 VAC buses.
The FLEX strategy credits the monitoring of plant parameters, either from the control room, using available electric power supplied from the batteries or taken locally. If instrumentation is to be monitored from the control room, it will be powered from 125 VDC either directly or through (future) inverters for 120 VAC to some instruments.
Figures 1 and 2 in the James A. FitzPatrick FLEX OIP submittal [3] provide the FLEX flow paths for James A. FitzPatrick Phases 1, 2 and 3. 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 James A. FitzPatrick 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], [31], [32], [33], [34], [35], [36], [37], and [38]. 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 BDBEE, as outlined in the James A. FitzPatrick OIP in Response to the March 12, 2012, Commission Order EA 049 [3] and is consistent with the third six
-month Status Report [
4]. The OIP provides the James A. FitzPatrick 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 James A. FitzPatrick OIP. 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 Page 7 James A. FitzPatrick ESEP Report 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 James A. FitzPatrick OIP. 2. The scope of components is limited to installed plant equipment, and FLEX connections necessary to implement the James A. FitzPatrick OIP as described in Section
- 2. 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, check valves and rupture disks.
Power-operated valves not required to change state as part of the FLEX mitigation strategies.
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.
3.1.1 ESEL Development The ESEL was developed by reviewing the James A. FitzPatrick OIP [3] 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 o ne-line drawings, system descriptions, design basis documents, as necessary.
Page 8 James A. FitzPatrick ESEP Report Cabinets containing electrical and instrumentation that could be affected by 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 Phase 1, RCIC is the primary path for inventory control and core cooling.
Therefore , the RCIC system was used as the basis for the Phase 1 and 2 ESEL. For Phase 2 and Phase 3, the RHR is used to provide the pathway for reactor pressure vessel injection utilizing the seismic grade fire pump or portable injection pump
- s. 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., RCIC)." To address this concern, the following guidance is applied in the James A. FitzPatrick ESEL for functional failure modes associated with power operated valves: Power operated valves that remain energized during the Extended Loss of AC Power (ELAP) events (such as DC powered valves), were included on the ESEL.
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 add ed 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.
Page 9 James A. FitzPatrick ESEP Report
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 th e
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 James A. FitzPatrick OIP [3] 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 RCIC is the primary system for Phases 1 and 2 and is presented as the single success path in the James A. FitzPatrick ESEL. RHR, Train A, is the primary system for Phase 3. Therefore, no additional justification is required.

4.2 Comparison
to SSE The SSE corresponds to a horizontal acceleration of 0.15g. The SSE is defined in Figure 2.6
-2 of the FSAR [39] in terms of a Peak Ground Acceleration (PGA) and a design response spectrum. These spectra have been digitized and tabulated
[40] [41]. Table 4-2 shows the spectral acceleration values at selected frequencies for the 5% damped horizontal SSE.

FitzPatrick The SSE envelops the GMRS for lower frequencies up to nearly 6 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 10 Hz range, provide criteria for accepting specific GMRS exceedances. However, the GMRS exceedances are not limited to the low frequency range and there are no narrow
-banded exceedances.
Therefore, these special screening considerations do not apply for James A. FitzPatrick and hence High Confidence of a Low Probability of Failure (HCLPF) evaluations are to be performed.
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 10 Hz range occurs at 10 Hz where the ratio is 0.233/0.15 = 1.55. The GMRS/SSE ratio is set to the scaling factor value of 1.55 for James A. FitzPatrick 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.

5.2 Method
to Estimate In-Structure Response Spectra (ISRS)
The RLGM ISRS for James A. FitzPatrick are generated by scaling the SSE ISRS [39]. The following steps are used to generate the RLGM ISRS.
- 2. Calculate the horizontal RLGM ISRS by scaling the horizontal direction SSE ISRS by a factor of 1.55. 3. Repeat steps 1 and 2 to obtain RLGM ISRS for multiple damping values.
The vertical direction RLGM ISRS is generated by repeating steps 1
-3 above using vertical direction SSE ISRS as input for multiple damping values and elevations. Page 14 James A. FitzPatrick ESEP Report
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:

[42]. 2. Probabilistic approach using the fragility analysis methodology of EPRI TR
-103959, Methodology for Developing Seismic Fragilities
[43]. 6.1 Summary of Methodologies Used James A. FitzPatrick performed a 0.3g focused
-scope SMA in accordance with the methodology of NUREG-1407[44] in 1996 as part of Individual Plant Examination of External Events (IPEEE) program.
The SMA is documented in [
45] and consisted of screening evaluations, seismic walkdowns, and a review of the plant seismic design basis. The SMA was performed in accordance with EPRI NP
-6041-SL [42]. The evaluation of mechanical and electrical equipment relied heavily on the walkdowns conducted for the USI A
-46 seismic evaluation. Section 3.3 and Appendix B of [
40] established that the results of the James A. FitzPatrick IPEEE are adequate to support screening of the updated seismic hazard for James A. FitzPatrick. Consequently, for ESEP, the results of HCLPF evaluations performed for IPEEE are used to screen out components with capacity that exceeds RLGM.
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 1.55xSSE with a PGA of 0.233 g, Figure 5-1. 6.2 HCLPF Screening Process For ESEP, the components are screened considering the RLGM (1.55xSSE) with a 0.233g PGA. The screening tables in EPRI NP
-6041-SL [42] 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 [42]. 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 th e screening caveats were met and for which the anchorage capacity exceeded the RLGM seismic demand Page 15 James A. FitzPatrick ESEP Report are screened out from ESEP seismic capacity determination because the HCLPF capacity exceeds the RLGM. The James A. FitzPatrick ESEL contains 145 items. Of these, 45 are valves
. In accordance with Table 2
-4 of EPRI NP
-6041-SL [42], active 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.
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 [42] screening caveats and the CDFM capacity exceeded the RLGM demand, the components are screened out from the ESEP capacity determination.
Additionally, items with HCLPF capacities greater than RLGM that were calculated in [
45] were also screened out.
Block walls located in the proximity of ESEL equipment were assessed for potential seismic interaction impact resulting from the RLGM by reviewing the existing plant documents and found to be acceptable.
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 [42] for the Seismic Margin Assessment process. Pages 2-26 through 2-30 of EPRI NP
-6041-SL [42] 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
-radioactive or low radioactive environments. Seismic capability assessment of components which are inaccessible, in high
-radioactive environments, or possibly within contaminated containment, will have to rely more on alternate means such as photographic inspection, 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 requiring an electrician or other technician to de
-energize and open cabinets or panels for 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 basis for assuming that the group of components are similar and are similarly anchored, then it is only necessary to inspect one component out of this group. The "similarity-basis" should be developed before the walkdown during the seismic capability preparatory work (Step 3) by reference to drawings, calculations or 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 representative component can be found so as to enable the inspection to be performed while the plant is in operation. At least for the one component of each type which is selected, anchorage should be thoroughly inspected.
Page 16 James A. FitzPatrick ESEP Report The walkdown procedure should 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/or specifications. If a one
-to-one correspondence is 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 construction pattern is typical. This procedure for inspection should be repeated for 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 construction practices are 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 different from that shown on drawings or prescribed in criteria for 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 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 responsible for the seismic adequacy of all elements which they screen from the margin review. Appendix D gives guidance for sampling selection." 6.3.2 Application of Previous Walkdown Information Several ESEL items were previously walked down during the James A. FitzPatrick seismic IPEEE program, for the 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 previous walkdown s, 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 [42], no significant outliers or anchorage concerns were identified during the James A. FitzPatrick seismic walkdowns. Based on walkdown results, no HCLPF capacity evaluations were required. 6.4 HCLPF Calculation Process ESEL items identified for ESEP at James A. FitzPatrick were evaluated using the criteria in EPRI NP
-6041-SL [42] and Section 5 o f EPRI 3002000704 [2]. Those evaluations included the following steps:
Performing seismic capability walkdowns for equipment not included in previous seismic walkdowns (USI A-46, IPEEE, or NTTF 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 Page 17 James A. FitzPatrick ESEP Report
6.5 Functional
Evaluations of Relays No seal in /lockout type relays were identified on James A. FitzPatrick ESEL. Therefore, no relay evaluations were performed.
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 [42] 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."
ESEL components were determined to have adequate capacity for the design basis loads and HCLPF greater than RLGM. 7.0 INACCESSIBLE ITEMS
7.1 Identification
of ESEL Item Inaccessible for Walkdowns Forty-four (44) components on the ESEL were previously identified as inaccessible and not walked down. All of these components were subsequently waked down, by plant personnel or the SRT, prior to or during the R22 refueling outage in January 2017. The results of the subsequent walkdowns and evaluations have been captured and summarized in Attachment B of this report.
No seismic concerns were identified and no detailed HCLPF evaluations were required as a result of outage walkdowns and evaluations.
7.2 Planned
Walkdown / Evaluation Schedule / Close Out No follow up walkdowns are required. Page 18 James A. FitzPatrick ESEP Report 8.0 ESEP CONCLUSIONS AND RESULTS 8.1 Supporting Information James A. FitzPatrick 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 James A. FitzPatrick response to the NRC's 50.54(f) letter. On March 12, 2014, NEI submitted to the NRC results of a study
[47] 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
[46] concluded that the "fleet wide seismic risk estimates are consistent with the approach and results used in the Gl
-199 safety/risk assessment." The letter also stated that "As a result, the staff has confirmed that the conclusions reached in Gl
-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 James A. FitzPatrick was included in the fleet risk evaluation submitted in the March 12, 2014 NEI letter
[47] therefore, the conclusions in the NRC's May 9 letter also apply to James A. FitzPatrick. 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 Page 19 James A. FitzPatrick ESEP Report 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. Based on the results of the screening evaluation performed in [
40], James A. FitzPatrick screens
-out of a risk evaluation. The NRC Screening and Prioritization Results letter concluded James A. FitzPatrick conditionally screens
-in for the seismic risk evaluation [
46] for the purpose of prioritizing and conducting additional evaluations. Consistent with [40] and detailed in this submittal, the IPEEE HCLPF Spectrum (IH S) bound the GMRS in the 1 Hz to 10 Hz range [48]. Upon further evaluation of information provided by Entergy, The NRC concluded that the IHS could be used for comparison with the GMRS for the screening decision. A seismic risk evaluation is not merited [
49]. Contingent upon NRC staff review and acceptance of Entergy's full scope IPEEE relay chatter review and spent fuel pool evaluation, the seismic hazard evaluation identified in enclosure 1 of the 50.54(f) letter [
1] will be completed.
8.2 Identification
of Planned Modifications Insights from the ESEP identified that there is no plant modification required.
8.3 Modification
Implementation Schedule There is no plant modification required.
8.4 Summary
of Regulatory Commitments No follow up actions or regulatory commitments are required for ESEP.
