A-1 Page 5 led A Document No.: 51-9257562-000 AREVA Arkansas Nuclear One HFE -High Frequency Confirmation Report 1.0 PURPOSE The purpose of this report is to provide information as requested by the Nuclear Regulatory Commission (NRC) in its March 12, 2012 letter issued to all power reactor licensees and holders of construction permits in active or deferred status (Reference

[ 1 ]). In particular, this report provides information requested to address the High Frequency Confirmation requirements ofltem (4), Enclosure 1, Recommendation 2.1: Seismic, of the March 12, 2012 letter (Reference

[1]). 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 (Reference

[1]), requesting information to assure that these recommendations are addressed by all U.S. nuclear power plants. The 50.54(t) letter requests that licensees and holders of construction permits-under, 10 CPR Part 50 reevaluate the seismic hazards at their sites against present-day NRC requirements and guidance.

Included in the 50.54(t) letter was a request that licensees perform a "confirmation, if necessary, that SSCs, which may be affected by high-frequency ground motion, will maintain their functions important to safety." EPRI 1025287, "Seismic Evaluation Guidance:

Screening, Prioritization and Implementation Details (SPID) for the resolution of Fukushima Near-Term Task Force Recommendation 2.1: Seismic" (Reference

[2]) provided screening, prioritization, and implementation details to the U.S. nuclear utility industry for responding to the NRC 50.54(t) letter. This report was developed with NRC participation and was subsequently endorsed by the NRC. The SPID included guidance for determining which plants should perform a High Frequency Confirmation and identified the types of components that should be evaluated in the evaluation.

Subsequent guidance for performing a High Frequency Confirmation was provided in EPRI 3002004396, "High Frequency Program, Application Guidance for Functional Confirmation and Fragility Evaluation," (Reference

[3]) and was endorsed by the NRC in a letter dated September 17, 2015 (Reference

[ 4]) . Final screening identifying plants to perform a High Frequency Confirmation was provided by NRC in a letter dated October 27, 2015 (Reference

[5]). This report describes the High Frequency Confirmation evaluation undertaken for Arkansas Nuclear One (ANO), Units 1 and 2. The objective of this report is to provide summary information describing the High Frequency Confirmation evaluations and results. The level of detail provided in the report is intended to enable NRC to understand the inputs used, the*evaluations performed, and the decisions made as a result of the evaluations.

EPRI 3002004396 (Reference

[3]) is used for the ANO engineering evaluations described in Appendix A of this report. In accordance with Reference

1.1 PURPOSE

The purpose of this report is to provide information as requested by the NRC in its March 12, 2012 50.54(f) letter issued to all power reactor licensees and holders of construction permits in active or deferred status [1]. In particular, this report provides requested information to address the High Frequency Confirmation requirements of Item (4), Enclosure 1, Recommendation 2.1: Seismic, of the March 12, 2012 letter [1].

1.2 BACKGROUND

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 (NTIF) 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 NTIF 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 S0.54(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.

Included in the 50.54(f) letter was a request that licensees perform a "confirmation, if necessary, that SSCs, which may be affected by high-frequency ground motion, will maintain their functions important to safety." EPRI 1025287, "Seismic Evaluation Guidance:

Screening, Prioritization and Implementation Details (SPID) for the resolution of Fukushima Near-Term Task Force Recommendation 2.1: Seismic" [2] provided screening, prioritization, and implementation details to the U.S. nuclear utility industry for responding to the NRC 50.54(f) letter. This report was developed with NRC participation and is endorsed by the NRC. The SPID included guidance for determining which plants should perform a High Frequency Confirmation and identified the types of components that should be evaluated in the evaluation.

Subsequent guidance for performing a High Frequency Confirmation was provided in EPRI 3002004396, "High Frequency Program, Application Guidance for Functional Confirmation and Fragility Evaluation," [3] and was endorsed by the NRC in a letter dated September 17, 2015 [4]. Final screening identifying plants needing to perform a High Frequency Confirmation was provided by NRC in a letter dated October 27, 2015 [S]. On March 28, 2014, Arkansas Nuclear One (ANO) submitted a reevaluated seismic hazard to the NRC as a part of the Seismic Hazard and Screening Report [6]. By letter dated October 27, 2015 [5], the NRC transmitted the results of the screening and prioritization review of the seismic hazards reevaluation.

This report describes the High Frequency Confirmation evaluation undertaken for ANO Units 1 and 2 using the methodologies in EPRI 3002004396, "High Frequency Program, Application Page 1of73 Controlled Document Arkansas Nuclear One: 50.54(f) NTIF 2.1 Seismic High Frequency Confirmation Guidance for Functional Confirmation and Fragility Evaluation," as endorsed by the NRC in a letter dated September 17, 2015 (4). The objective of this report is to provide summary information describing the High Frequency Confirmation evaluations and results. The level of detail provided in the report is intended to enable NRC to understand the inputs used, the evaluations performed, and the decisions made as a result of the evaluations.

1.3 APPROACH

EPRI 3002004396 (3) is used for the ANO 1&2 engineering evaluations described in this report. Section 4.1 of Reference

[3] provided general steps to follow for the high frequency confirmation component evaluation.

Section 4.2.2 of Reference

[3] describes an alternate approach that uses the plant's Individual Plant Examination of External Events (IPEEE). This approach also corresponds with "Path 3" from NEI 12-06 Appendix H [9]. Reference

[6] establishes the adequacy of the IPEEE for AN0-1 and AN0-2, and the full-scope relay evaluations contained therein. Therefore, the selection of components for high-frequency (HF) confirmation is based on the relays identified in the IPEEE. Accordingly, the following topics are addressed in the subsequent sections of this report:

• ANO SSE and GMRS Information

• Selection of components and a list of specific components for high-frequency confirmation

• Estimation of seismic demand for subject components

• Estimation of seismic capacity for subject components

• Summary of subject components' high-frequency evaluations

• Summary of Results 1.4 PLANT SCREENING ANO submitted reevaluated seismic hazard information including GMRS and seismic hazard information to the NRC on March 28, 2014, [6]. In a letter dated December 15, 2015 the NRC staff concluded that the submitted GMRS adequately characterizes the reevaluated seismic hazard for ANO [21). The NRC final screening determination letter [5] concluded that the ANO GMRS to SSE comparison resulted in a need to perform a High Frequency Confirmation in accordance with the screening criteria in the SPID [2]. Page 2 of 73 Controlled Document Arkansas Nuclear One: 50.54(f) NTIF 2.1 Seismic High Frequency Confirmation 2 Selection of Components for High-Frequency Screening The fundamental objective of the high frequency confirmation review is to determine whether the occurrence of a seismic event could cause credited equipment to fail to perform as necessary.

An optimized evaluation process is applied that focuses on achieving a safe and stable plant state following a seismic event. As described in Reference

[3], this state is achieved by confirming that key plant safety functions critical to immediate plant safety are preserved (reactor trip, reactor vessel inventory and pressure control, and core cooling) and that the plant operators have the necessary power available to achieve and maintain this state immediately following the seismic event (AD/DC power support systems).

For AN0-1 & 2, the components supporting the key safety functions have been determined by the IPEEE. The description of key safety functions, and the plant systems and success paths that are credited to achieve these functions is described in the IPEEE reports for safe shutdown success path selection

[12] [13]. The specific equipment credited in the IPEEE to achieve these success paths is captured on the safe shutdown equipment list (SSEL) [14] [15]

that was created specifically for the IPEEE/USI A-46 seismic analysis.

The key functions fulfilled by the IPEEE safe shutdown success paths are given in Table 2-1. Table 2-1: IPEEE Key Functions ) Reactivity Control Reactor Pressure Control Reactor Inventory Control Decay Heat Removal The primary success paths for the ANO units are shown in Figure 2-1 and Figure 2-2 derived from [12], Figure 2 and [13], Figure 2. The IPEEE includes alternate success paths not shown in the figures since, generally, they consist of using the redundant trains to achieve the key functions.

The IPEEE has already reviewed these circuits, determined if seismic induced relay chatter would prevent the completion of these key functions, and has identified the essential relays involved.

Therefore, the selection of relays and contact control devices for the HF confirmation is based upon the essential relay list (ERL) developed by the IPEEE, which is contained in the AN0-1 & 2 IPEEE relay evaluation reports [10] [11]. The ERL from the IPEEE was first reviewed for current applicability, and adjustments were made to accommodate changes that have occurred since performance of the IPEEE. This revised essential relay list then comprises the components selected for HF confirmation.

2.1

SUMMARY

OF DESIGN CHANGES SINCE IPEEE Since the IPEEE is several years old, a systematic review of design changes since performance of the IPEEE was undertaken to ensure that there were none that would affect the selection of essential relays. A summary of the applicable design changes is described below. The purpose of this review was to verify that the relays on the IPEEE ERL for AN0-1 and AN0-2 are still applicable, and to identify any design changes that may be relevant for the HF confirmation.

Design changes that affect a circuit with an essential relay were flagged for new circuit analysis.

Design changes affecting the ERL were not extensive, and were generally favorable with respect to relay chatter. One significant design change involved replacement of the 120VAC inverters at both units. The inverters along with their integral control circuits were replaced with new and improved models. Therefore, the inverters were flagged for new circuit analysis and the essential relays from the new control circuits were added to the ERL. Other design changes, as described in the sections below, were benign with respect to relay chatter. Each relay on the ERL was also searched in the plant data base to identify current manufacturer and model. Obsolete relays that are replaced with functionally-equivalent models from a different manufacturer do not require new circuit analysis.

The current model information for all of the essential relays was determined from the plant database for use in the HF confirmation.

2.1.1 Summary

of Design Changes for AN0-1 The inverters Y11, Y13, Y22, Y24 were replaced along with their integral control circuits.

Several relays from the ERL were removed with this design change. The new inverters received circuit analysis to determine if there are any relays from the new control circuits that should be on the ERL. In addition,

• inverter Y28 (the UPS inverter) was eliminated and its loads added to the new Y22 inverter.

Magna blast breakers on bus A-3 were replaced with Siemens vacuum interrupter type breakers.

The breakers are functionally equivalent with respect to the control circuit, so relays on the ERL are not affected except for one, the anti-pump relay 152Y, which is integral to the breaker. The new breaker has a functionally-equivalent relay. The circuits for several components were modified to prevent spurious operation due to fire-induced hot shorts. Affected components include three valves and two sluice gates whose motor starter seal-in contacts are already on the ERL. The changes involve installation of inhibit circuits in the motor-starter circuit. The inhibit circuit adds a new normally-closed contact to the "hot" end of the motor starter Page 6 of 73 led ment Arkansas Nuclear One: 50.54(f) NTTF 2.1 Seismic High Frequency Confirmation relay coil to keep it grounded when not in use. This contact is mechanically linked to the normally open seal-in contact in a "break before make" design. A review of these circuits determined that the new inhibit circuit does not add any new chatter failure modes of concern, nor changes any existing chatter failure modes on the ERL. Therefore, the circuit analysis concluded that the design change of the inhibit circuits was benign with respect to chatter, and did not increase nor decrease the essential relay count. Relays from the ERL are no longer relevant for valve CV-1050 because the valve is unpowered at the MCC breaker during normal operation.

Relays for valves CV-3641 and CV-3645 are removed from the ERL because these valves have been converted to manual valves. Obsolete speed sensors on the EDGs were replaced with functional equivalents.

Various obsolete relays have been replaced since IPEEE with functional equivalents from another manufacturer.

The current relay models have been identified from the plant database.

2.1.2 Summary

of Design Changes for AN0-2 The inverters 2Y11, 2Y13, 2Y22, 2Y24 were replaced along with their' integral control circuits.

Several relays from the ERL were removed with this design change. The new inverters received circuit analysis to determine if there are any relays from the new control circuits that should be on the ERL. Magna blast breakers on 4160 volt bus 2A-3 were replaced with Siemens vacuum interrupter type breakers.

The breakers are functionally equivalent with respect to the control circuit, so relays on the ERL are not affected.

At AN0-2, there were also some NFPA 805 modifications to prevent fire-induced spurious actuations, but they were limited to cable rerouting, and did not involve the functional aspects of relay circuits.

Relays from the ERL are no longer relevant for valves 2CV5084-1 and 2CV5086-2 because the valves are unpowered at the MCC breaker during normal operation.

Various obsolete relays have been replaced since IPEEE with functional equivalents from another manufacturer.

The current relay models have been identified from the plant database.

2.2 SSEL ENHANCEMENT The IPEEE is based on a safe shutdown equipment list (SSEL) that was created specifically for the seismic analysis [14] [15]. These references identify the equipment that is required to bring the plant to a safe shutdown condition following an earthquake and to maintain it there for a minimum of seventy-two hours. There is another SSEL in the plant data management system (PDMS) that is more recent than the IPEEE. This SSEL contains equipment selected to demonstrate the plant's ability to achieve post-fire safe shutdown in accordance with 10 CFR 50, Appendix R.1 . Since this other SSEL was created specifically for Appendix R fire scenarios, it has different scope and boundary conditions, which may not be applicable to Seismic. Major differences are that Appendix R does not assume a simultaneous LOCA while the 1 Note that as of this writing, AN0-2 is an NFPA 805 plant, and AN0-1 has plans to be an NFPA 805 plant. Page 7 of 73 Controlled Document Arkansas Nuclear One: 50.54(f) NITF 2.1 Seismic High Frequency Confirmation IPEEE does, and Appendix R mitigation is allowed to credit non-seismically qualified components.

For the purpose of conservatism and completeness, the SSEL from the PDMS was reviewed to determine if there are any components on it, not on the original IPEEE SSEL, that should be considered for inclusion in the seismic analysis [16]. After screening out components that are uniquely applicable to Appendix R scenarios (e.g., non-safety-related equipment that cannot be credited for Seismic) or not applicable to HF chatter evaluation (e.g., no automatic control function), a small number of additional components were added to the HF confirmation scope. Functionally speaking, the additional components add success paths and functions that are not necessary to meet the minimum IPEEE requirements, but may in any event provide an enhanced level of redundancy.

For example, this enhanced SSEL includes an additional steam supply path to the turbine-driven EFW pump, additional isolation valves, battery chargers, swing-train inverters, and potential flow diversion pathways.

Circuit analysis was performed on these components to determine if there are any corresponding essential relays that could interfere with the desired function of the components.

As a conservative measure, the resulting relays are included on the ERL along with the relays resulting from the IPEEE by itself. 2.3 EXAMPLES OF CIRCUIT ANALYSIS TO IDENTIFY ESSENTIAL RELAYS Circuit analysis was performed for the components that have changed or are new since the IPEEE. The "essential relays" determined from the circuit analysis are the contact control devices in seal-in or lockout circuits whose change of state may be detrimental to a key safe shutdown function.

The various EPRI guidance documents [3] [7] [8] [17] [18] [19]

[20] provide the basis for the circuit analysis assumptions:

• Only the relays that are in seal-in and lock-out circuits need to be considered.

This includes relays in the upstream circuit that may trigger the lock-out or seal-in function ([3] and [20]).

• Mechanically-actuated switches are considered "inherently robust." This category includes:

manually-operated control switches, power transfer switches, limit and torque switches and position switches ([3] and [19]).

• Molded case circuit breakers (MCCB) are not vulnerable to HF chatter ([3]).

• Lock-out relays are not vulnerable to HF chatter; however up-stream contacts in the control circuit that can trip the lock-out relay are of potential concern ([3]).

• Solid state relays (no mechanically moving parts) are considered inherently rugged ([3] and [19]).

• Induction disk (rotary) relays have high seismic capacity and are considered inherently rugged ([17] and [18]). Chatter vulnerability is determined only by the seal-in contacts that may actuate the relay.

• Process switches (i.e., mechanical sensor switches) such as pressure and thermal switches (thermostats) that have contacts in these control circuits may chatter and are included in the evaluation.

• The relays of potential concern are used primarily for the direct control of power equipment such as breakers, switchgear, and valve operators.

However, the breakers and power equipment are not included in the evaluation because they have not shown vulnerability to chatter ([19]). If there is chatter of breaker contacts, the short interruption of electrical current is not of sufficient duration to adversely affect the powered component (e.g., a motor). It is the Page 8 of 73 Controlled Docurn Arkansas Nuclear One: 50.54(f) NTIF 2.1 Seismic High Frequency Confirmation upstream control circuit relays that seal-in to operate the breaker that are the primary target of this evaluation.

• Motor starters with seal-in contacts have been included in the evaluation.

These are contactors that are used to start motors such as for MOVs and pumps. A contactor is considered to be a heavy-duty relay, and is distinguished from a breaker in that its contacts are moved by a solenoid type mechanism rather than charged by springs.

• For the purposes of this evaluation, the shaking from the earthquake is assumed to last 30 seconds. 2.3.1 Circuit Analysis Example 1: Unit 1 MOV with Only Handswitch Actuation Figure 2-3 depicts the opening circuit of an MOV. The valve is normally closed and opening is an undesired action. The valve is controlled remotely by handswitch in the control room and locally by pushbutton.

Chatter could shut contacts 42F/a, seal-in the opening motor contactor, and drive the valve completely open. As such, this motor contactor (42F) would be included in the ERL. T2 T3 I Figure 2-3: Seal-in of MOV Opening Circuit .il31 I'[ ___ _

-, 2.3.2 Circuit Analysis Example 2: Unit 2 SOV with Automatic Actuation Figure 2-4 shows powe.r scheme for an SOV which controls the position of AOV 2CV-4941-2.

The solenoid must be powered to be open as indicated by the FC (fail closed) designation for 2SV-4941-2.

The solenoid must be open to keep 2CV-4941-2 open. The power to this solenoid can be interrupted by several avenues. This arrangement interlocks the open position of CV-4941 to the position of CV-4926 though relay 63X-4926 and interposing relay 94/4941-2 and the position of CV-4928 through 2HS-4928.

The normal opening and closing of the solenoid is controlled through contacts of 63X-4857A which is in turn controlled by a VCT level switch. The solenoid can also be closed by the ESFAS with a SIAS signal opening its associated contact. Normally all of the aforementioned contacts would be closed to keep 2SV-4941-2 energized and CV-4941 open. The 63X contact opens and shuts from time to time to automatically control VCT level. If the 63X contact is closed, chatter could open the contacts for 63X, SIAS, or 94/4941-2 causing the solenoid to shut. However, closed is the desired safe shutdown position for this particular valve. If the 63X contact is open, chatter could cause it to close opening the solenoid.

However, the 63X contact has no seal-in capability and would re-open in short In summary although there are several contact devices that participate in the control of this valve, chatter is acceptable because the safe shutdown position for this valve is closed.

2.4 CONTRIBUTIONS

FOR HF EVALUATION

2.4.1 Changes

to the Essential Relay Lists There are several relays from the original IPEEE ERLs that are no longer applicable, due to the design changes, and do not need HF confirmation analysis.

New relays were also added to the ERL from the design changes described in Section 2.1. Specifically, the new inverters added several essential relays for each unit, to replace the ones that were retired with the old inverters.

The deletions and additions produce a revised ERL. There are some relays on the revised ERL that are not a concern for high-frequency evaluation because of a mitigating factor, such as the resolution credited in the IPEEE applies also to HF vibration.

For example, the resolution took credit for an operator action in the emergency operating procedures (EOP), or the relay failure was determined to have no consequence.

Since these resolutions do not exclude high-frequency vibration, they are still applicable.

Only the relays pertinent to high frequency evaluation are considered further. 2.4.2 Enhanced SSEL Contribution from Appendix R A few essential relays were found from the Enhanced SSEL. These include relays associated with a redundant steam supply path to the Turbine-driven EFW pump from a steam generator (both units), spurious actuation of containment spray (potential flow diversion, both units), spurious operation of core flood tank vent valves (unit 1), spurious operation of MSIV bypass valves (unit 2), premature operation of volume control tank isolation (unit 2) and EDG overspeed switches (unit 2). Similar to Section 2.4.1, some of these essential relays are not a concern for high frequency evaluations because of a mitigating factor, for example crediting a justifiable operator action. Only the relays pertinent to high frequency evaluation are considered further. 2.4.3 Merging the Contributions For all of the relays contributed from the revised ERL and the Enhanced SSEL, the current information from the plant data base for the model, manufacturer, and location of each relay has been documented (see Section 2.5). This is input to the civil analysis team for high-frequency confirmation (see Section 3 and 4). Some of the essential relays from the IPEEE have changed manufacturer and model from the original analysis.

This is primarily due to replacement of obsolete relays with newer models. In these cases the new relay is the functional equivalent of the original relay and so does not change its status as an essential relay. The HF confirmation analysis uses the current model information.

SUMMARY

OF SELECTED COMPONENTS A list of the contact devices requiring a high frequency confirmation is provided in Attachment B. Page 12 of 73 Controlled Docun1ent Arkansas Nuclear One: 50.54(f) NTIF 2.1 Seismic High Frequency Confirmation 3 Seismic Evaluation

3.1 HORIZONTAL

SEISMIC DEMAND Per Reference

[3], Sect. 4.3, the basis for calculating high-frequency seismic demand on the subject components in the horizontal direction is the ANO horizontal ground motion response spectrum (GMRS), which was generated as part of the ANO Seismic Hazard and Screening Report [6] submitted to the NRC on March 28, 2014 and accepted by the NRC on December 15, 2015 [21]. It is noted in Reference

[3] that a Foundation Input Response Spectrum (FIRS) may be necessary to evaluate buildings whose foundations are supported at elevations different than the Control Point elevation.

However, for sites founded on rock, per Reference

[3], "The Control Point GMRS developed for these rock sites are typically appropriate for all rock-founded structures and additional FIRS estimates are not deemed necessary for the high frequency confirmation effort." Section 3.3 of Reference

[6] notes that safety-related structures at ANO are founded on rock. Combining this condition with the justification provided in section 3.3 of Reference

[3] on when a FIRS would normally be defined, the GMRS is judged appropriate for use as the site review level ground motion for high frequency evaluations.

The horizontal GMRS values are provided in Table 3-2. 3.2 VERTICAL SEISMIC DEMAND As described in Section 3.2 of Reference

[3], the horizontal GMRS and site soil conditions are used to calculate the vertical GMRS (VG MRS), which is the basis for calculating high-frequency seismic demand on the subject components in the vertical direction.

The site's soil mean shear wave velocity vs. depth profile is provided in Reference

[6], Table 2.3.2-1 (Profile 1) and partially reproduced below in Table 3-1. Page 13 of73

[3], Section 3.5.

• The time for a shear wave to travel through each soil layer is calculated by dividing the layer depth (d;) by the shear wave velocity of the layer (Vs;).

• The total time for a wave to travel from a depth of 30m to the surface is calculated by adding the travel time through each layer from depths of Om to 30m

• The velocity of a shear wave traveling from a depth of 30m to the surface is therefore the total distance (30m) divided by the total time; i.e., Vs30 =

The site's soil class is determined by using the site's shear wave velocity (Vs30) and the peak ground acceleration (PGA) of the GMRS and comparing them to the values within Reference

[3], Table 3-1. Based on the PGA of 0.24g and the shear wave velocity of 5,324ft/s, the site soil class is Class B-Hard. Once a site soil class is determined, the mean vertical vs. horizontal GMRS ratios (V/H) at each frequency are determined by using the site soil class and its associated V/H values in Reference

[3], Table 3-2. The vertical GMRS is then calculated by multiplying the mean V/H ratio at each frequency by the horizontal GMRS acceleration at the corresponding frequency.

It is noted that Reference

[3], Table 3-2 values are constant between 0.1Hz and 20Hz for Class B-Hard soil sites. The V /H ratios and VG MRS values are provided in Table 3-2 of this report. Figure 3-1 below provides a plot of the horizontal GMRS, V/H ratios, and vertical GMRS for ANO.

[3], the peak horizontal acceleration is amplified us i ng the follow i ng two factors to determine the horizontal in-cabinet response spectrum:

• Horizontal in-structure amplification factor AFsH to account for seismic amplification at floor elevations above the host building's foundation

• Horizontal in-cabinet amplification factor AF cH to account for seismic amplification within the host equ i pment (cabinet, switchgear, motor control center, etc.) The in-st r ucture amplification factor AF sH is derived from Figure 4-3 in Reference

[3]. The incabinet amplification factor , AF cH is associated with a given type of cabinet construction.

The three general cab i net types are identified in Reference

[3] and Appendix I of EPRI NP-7148 [19] assuming 5% in-cabinet response spectrum damping. EPRI NP-7148 [19] classified the cabinet types as high amplification structures such as switchgear panels and other similar large flexible panels, medium amplification structures such as control panels and control room bench board panels and low amplification structures such as motor control centers. All of the electrical cabinets containing the components subject to high frequency confirmation (see Table B-1 in Attachment B) can be categorized into one of the in-cab i net amplification categories in Reference

[3] as follows: Page 16 of 73 Document Arkansas Nuclear One: 50.54(f) NTIF 2.1 Seismic High Frequency Confirmation

• Motor Control Centers are identified on the screening evaluation work sheets (SEWS) for equipment class 1 during the USI A-46 effort. These cabinets qualify as low amplification cabinets and receive an in-cabinet amplification factor of 3.6.

• Switchgear cabinets are identified on the SEWS for equipment classes 2 and 3 during the USI A-46 effort. These cabinets qualify as high amplification cabinets and receive an cabinet amplification factor of 7.2. The switchgear amplification factor is used when uncertainty exists in the applicability of lower amplification cabinet categories.

• Control cabinets consist of cabinets with height-to-depth ratios of about 3 (with a maximum height of 8ft) which results in moderate frame stresses and damping. The* response levels are mid-range between MCCs and switchgear and therefore these cabinets can be considered in the medium amplification category and receive an cabinet amplification factor of 4.5. The amplification factors for the in-cabinet responses are based on the worst location within a generic cabinet. Therefore, if the relays are mounted away from this worst case location, a reduction to the amplification factor can be taken. If the relay were mounted on the floor, this amplification factor would by definition be equal to 1.0. Assuming a linear relationship from the floor to the top of the cabinet, a different amplification factor can be determined for the bottom third and middle third of the cabinet. While this reduction does not directly consider the local panel vibration modes, the use of a linear relationship (instead of a non-linear mode shape similar to a cantilever deflection) and grouping the cabinet into thirds is considered to still be conservative.

3.4 COMPONENT

VERTICAL SEISMIC DEMAND The component vertical demand is determined using the. peak acceleration of the VG MRS between 15 Hz and 40 Hz and amplifying it using the following two factors:

• Vertical in-structure amplification factor AFsv to account for seismic amplification at floor elevations above the host building's foundation

• Vertical in-cabinet amplification factor AFcv to account for seismic amplification within . the host equipment (cabinet, switchgear, motor control center, etc.) The in-structure amplification factor AFsv is derived from Figure 4-4 in Reference

[3]. The cabinet amplification factor, AFcv is derived in Reference

[3) and is 4.7 for all cabinet types. Page 17 of73 Arkansas Nuclear One: 50.54(f) NTTF 2.1 Seismic High Frequency Confirmation 4 Contact Device Evaluations Per Reference

[3], seismic capacities (the highest seismic test level reached by the contact device without chatter or other malfunction) for each subject contact device are determined by the following procedures:

(1) If a contact device was tested as part of the EPRI High Frequency Testing program [8], then the component seismic capacity from this program is used. (2) If a contact device was not tested as part of [8], then one or more of the following means to determine the component capacity were used: (a) Device-specific seismic test reports (either from ANO or from the Seismic Qualification Reporting

& Testing Standardization (SQURTS) testing program. (b) Generic Equipment Ruggedness Spectra (GERS) capacities per [17], [18], [22], and [23]. (c) Assembly (e.g. electrical cabinet) tests where the component functional performance was monitored.

The high-frequency capacity of each device was evaluated with the component mounting point demand from Section 3 using the criteria in Section 4.5 of Reference

[3]. A summary of the high-frequency evaluation conclusions is provided in Table B-1 in Attachment B. Page 18 of 73 Controlled Docun1ent Arkansas Nuclear One: 50.54(f) NTIF 2.1 Seismic High Frequency Confirmation 5 Conclusions

5.1 GENERAL

CONCLUSIONS ANO has performed a High Frequency Confirmation evaluation in response to the NRC's 50.54(f) letter [1] using the methods in EPRI report 3002004396

[3]. The evaluation identified a total of 394 components that required evaluation.

As summarized in Table B-1 in Attachment B, devices with evaluation result of 'confirmed' have adequate seismic capacity.

Components requiring further resolution following the criteria in Section 4.6 of Reference

[3] are identified in Table B-1 in Attachment Band listed separately in Table C-1 of Attachment C. Furthermore, Table C-1 includes a description of the outlier resolution.

5.2 IDENTIFICATION

At AN0-2, there are a total of four (4) operator actions required at a total of four (4) locations.

For AN0-1, the comprehensive scope of operator actions required for outlier relays is listed below: Depress two pushbuttons (one on both 'A' red and 'B' green trains)

Reset two lockout relays (one on both red and green trains) Close ten (10) breakers located on the A3 Bus (red train) Close nine (9) breakers located on the A4 Bus (green train) For AN0-2, the comprehensive scope of operator actions required for outlier relays is listed below: Reset two lockout relays (one on both red and green trains) Close one (1) breaker located on the 2A3 Bus ('A' red train) Close one (1) breaker located on the 2A4 Bus ('B' green train) Procedural guidance for the operator actions defined above is provided in existing ANO procedures as detailed in Reference

[17], the model tested was a CR120A02202AA, which is an exact match for the relay at AN0-1. For the CR120A02202AA relay, a high frequency capacity of 9g is used along with an FK = 1.5 (the capacity knockdown factor, FK, is determined based on the test source as provided in Table 4-2 of Reference

[3]). The table below contains the complete list of GE CRl 20A02202AA relays along with their respective capacity to demand ratios. The minimum capacity to demand ratio is 1.70 for the horizontal and 2.38 for the vertical checks. A.3 GE 12GGP53B1A Relay Evaluation The Generic Equipment Ruggedness Spectrum (GERS) for the GE GGP53B series relays are presented starting on page B-87 of Reference

[17]. Per Reference

[17], the important model number characters that affect ruggedness have been identified.

For the 12GGP53B1A relays, a high frequency capacity of 5g is used along with an FK = 1.5 (the knockdown factor, FK, is determined based on the test source as provided in Table 4-2 of Reference

[3]). The table below contains the complete list of GE GGP Series relays along with their respective capacity to demand ratios. The minimum capacity to demand ratio is 0.45 for the horizontal and 1.27 for the vertical checks. Both the 12GGP53B lA are outliers as they have capacity to demand ratios less than one. Note that these relays are located in switchgear A-3 and A-4, which consist of a long line of side by side cabinets and may be able to take advantage of using the multi-axis to single axis correction factor (i.e. FMs = 1.2). However, this factor alone would not change the outlier status of the relays.
