On March 12, 2012, the Nuclear Regulatory Commission (NRC) issued a Request for Information per 10 CFR 50.54(f) (Reference 1) to all power reactor licensees. The required response section of Enclosure 1 of Reference 1 indicated that licensees should provide a Seismic Hazard Evaluation and Screening Report within 1.5 years from the date of the letter for Central and Eastern United States (CEUS) nuclear power plants. By NRC letter dated May 7, 2013 (Reference 2), the date to submit the report was extended to March 31, 2014.

By letter dated May 9, 2014 (Reference 6), the NRC transmitted the results of the screening and prioritization review of the seismic hazards reevaluation report for Byron Station, Units 1 and 2 submitted on March 31, 2014 (Reference 5). In accordance with the screening, prioritization, and implementation details report (SPID) (References 3 and 4), and Augmented Approach guidance (Reference 2), the reevaluated seismic hazard is used to determine if additional seismic risk evaluations are warranted for a plant. Specifically, the reevaluated horizontal ground motion response spectrum (GIVIRS) at the control point elevation is compared to the existing safe shutdown earthquake (SSE) or Individual Plant Examination for External Events (IPEEE) High Confidence of Low Probability of Failure (HCLPF) Spectrum (IHS) to determine if a plant is required to perform a high frequency confirmation evaluation. As noted in the May 9, 2014 letter from the NRC (Reference 6) on page 4 of Enclosure 2, Byron Station, Units 1 and 2 is to conduct a limited scope High Frequency Evaluation (Confirmation).

Within the May 9, 2014 letter (Reference 6), the NRC acknowledged that these limited scope evaluations will require additional development of the assessment process. By Reference 8, the Nuclear Energy Institute (NEI) submitted an Electric Power Research Institute (EPRI) report entitled, High Frequency Program: Application Guidance for Functional Confirmation and Fragility Evaluation (EPRI 3002004396) for NRC review and endorsement. NRC endorsement was provided by Reference 9. Reference 10 provided the NRC final seismic hazard evaluation

U.S. Nuclear Regulatory Commission Seismic Hazard 2.1 High Frequency Supplement November 2, 2016 Page 3 screening determination results and the associated schedules for submittal of the remaining seismic hazard evaluation activities.

The High Frequency Evaluation Confirmation Report for Byron Station, Units 1 and 2, provided in the enclosure to this letter, shows that all high frequency susceptible equipment evaluated within the scoping requirements and using evaluation criteria of Reference 8 for seismic demands and capacities, are acceptable. Therefore, no additional modifications or evaluations are necessary.

This letter closes Commitment No. 1 in Reference 5.

This letter contains no new regulatory commitments.

l5CO345-RPT-OO2, Rev. O Correspondence No.: RS-16-175 Executive Summary The purpose of this report is to provide information asrequested by the Nuclear Regulatory Commission (NRC)ln its March 12 2O12 letter issued to all power reactor licensees and holders of construction permits in active or deferred status [I]. In particular, this report provides information requested to address the High Frequency Confirmation requirements of Item (4), Enclosure 1, Recommendation 2.1: Seiarnlo,of the March 12,2O12 letter [l].

Following the accident atthe FukushlnmaDal-lchl nuclear power plant resulting from the March Il, 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 [15] 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. 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."

EPRl IO25287, "Seismic Evaluation Guidance: Screening, Prioritization and Implementation Details (SPID) for the resolution of Fukushima Near-Term Task Force Recommendation 2.1: Seismic" [6]

provided screening, prioritization, and implementation details tothe U.S. nuclear utility industry for responding to the NRC 50.54(f) 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 ln the evaluation.

Subsequent guidance for performing a High Frequency Confirmation was provided in EPRI 3002004396.1 "High Frequency Program, Application Guidance for Functional Confirmation and Fragility Evaluotlon,"[8] and was endorsed by the NRClne letter dated September I7,2O15[3].

Final screening identifying plants needing to perform a High Frequency Confirmation was provided byNRClno letter dated October 27,2OI5[2].

This report describes the High Frequency Confirmation evaluation performed for Byron Nuclear Power Station, Units 1and 2(BYR). The objective of this report lsto 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 aso result ofthe evaluations.

15C0346-RPT-002, Rev. 0 Correspondence No.: RS-16-175 1 Introduction 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].

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. 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" [6] 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," [8] and was endorsed by the NRC in a letter dated September 17, 2015 [3].

Final screening identifying plants needing to perform a High Frequency Confirmation was provided by NRC in a letter dated October 27, 2015 [2].

On March 31, 2014, BYR submitted a reevaluated seismic hazard to the NRC as a part of the Seismic Hazard and Screening Report [4]. By letter dated October 27, 2015 [2], 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 BYR using the methodologies in EPRI 3002004396, "High Frequency Program, Application Guidance for Page 4 of 75

15C0346-RPT-002, Rev. 0 Correspondence No.: RS-16-175 Functional Confirmation and Fragility Evaluation," as endorsed by the NRC in a letter dated September 17, 2015 [3].

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 conclusions made as a result of the evaluations.

1.3 APPROACH EPRI 3002004396 [8] is used for the BYR evaluations described in this report. Section 4.1 of Reference [8] provided general steps to follow for the high frequency confirmation component evaluation. Accordingly, the following topics are addressed in the subsequent sections of this report:

• BYR 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 BYR submitted reevaluated seismic hazard information including GMRS and seismic hazard information to the NRC on March 31, 2014 [4]. In a letter dated February 17, 2016, the NRC staff concluded that the submitted GMRS adequately characterizes the reevaluated seismic hazard for the BYR site for 2.1 Seismic [14].

The NRC final screening determination letter concluded [2] that the BYR GMRS to SSE comparison resulted in a need to perform a High Frequency Confirmation in accordance with the screening criteria in the SPID [6].

1.5 REPORT DOCUMENTATION Section 2 describes the selection of devices. The identified devices are evaluated in Reference

[190] for the seismic demand specified in Section 3 using the evaluation criteria discussed in Section 4. The overall conclusion is discussed in Section 5.

Table B-1 lists the devices identified in Section 2 and provides the results of the evaluations performed in accordance with Section 3 and Section 4.

Page 5 of 75

15C0346-RPT-002, Rev. 0 Correspondence No.: RS-16-175 Selection Screening The fundamental objective of the high frequency confirmation review is to determine whether the occurrence of a seismic event could cause credited FLEX/mitigating strategies 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 [8], 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 (AC/DC power support systems).

Within the applicable functions, the components that would need a high frequency confirmation are contact control devices subject to intermittent states in seal-in or lockout circuits. Accordingly, the objective of the review as stated in Section 4.2.1 of Reference [8] is to determine if seismic induced high frequency relay chatter would prevent the completion of the following key functions.

2.1 REACTOR TRIP/SCRAM The reactor trip/SCRAM function is identified as a key function in Reference [8] to be considered in the High Frequency Confirmation. The same report also states that "the design requirements preclude the application of seal-in or lockout circuits that prevent reactor trip/SCRAM functions" and that "No high-frequency review of the reactor trip/SCRAM systems is necessary."

2.2 REACTOR VESSEL INVENTORY CONTROL The reactor coolant system/reactor vessel inventory control systems were reviewed for contact control devices in seal-in and lockout (SILO) circuits that would create a Loss of Coolant Accident (LOCA). The focus of the review was contact control devices that could lead to a significant leak path. Check valves in series with active valves would prevent significant leaks due to misoperation of the active valve; therefore, SILO circuit reviews were not required for those active valves.

The process/criteria for assessing potential reactor coolant leak path valves is to review all P&ID's attached to the Reactor Coolant System (RCS) and include all active isolation valves and any active second valve upstream or downstream that is assumed to be required to be closed during normal operation or close upon an initiating event (LOCA or Seismic). A table with the valves and associated P&ID is included in Table B-2 of this report.

Manual valves that are normally closed are assumed to remain closed and a second simple check valve is assumed to function and not be a Multiple Spurious Failure.

Active Function: A function that requires mechanical motion or a change of state (e.g., the closing of a valve or relay or the change in state of a transistor)

Simple Check Valve: A valve which closes upon reverse fluid flow only.

15C0346-RPT-002, Rev. 0 Correspondence No.: RS-16-175 The Letdown and Purification System on PWRs is a normally in service system with the flowpath open and in operation. If an event isolated a downstream valve, there are pressure relief valves that would flow water out of the RC System. Letdown has auto isolation and abnormal operating procedure which isolate the flow. There are no auto open valves in this flowpath.

Table B-2 contains a list of valves analyzed and the resultant devices selected which are also identified in the section below. Based on the analysis detailed below, there are no moving contact control devices which could create a LOCA due to chatter-induced sustained valve misalignment, and thus no devices were selected for this category.

Reactor Coolant Loop Valves Drain Line Valves 1RC8037A/B/C/D, 2RC8037A/B/C/D, Reactor Head Vent Valves 1RC014A/B/C/D, 2RC014A/B/C/D Electrical control for the solenoid-operated pilot valves is via a rugged hand control switch.

There are no chatter sensitive contact devices involved in the control of these valves [21, 22, 23, 24].

Pressurizer Power Operated Relief Valves 1RY455A, 1RY456, 2RY455A, 2RY456, Blocking Valves 1RY8000A/B,2RY8000A/B Electrical control for the solenoid-operated pilot valves is via relays which are energized from process control signals. There are no devices which could seal-in and cause a sustained undesirable opening of the Pressurizer Power Operated Relief Valves [25, 26, 27, 28, 29, 30].

For this reason, these valve controls can be credited in a high frequency event, and analysis of the Blocking Valve controls is unnecessary.

Residual Heat Removal Valves Reactor Coolant Loop to Residual Heat Removal Pump Isolation Valves 1RH8701A-1/1B-2/2A-1/213-2, 2RH8701A-1/113-2/2A-1/213-2 Both the MID and control schematic diagrams indicate 1RH8701B-2, 1RH8702A-1, 2RH870113-2, and 2RH8702A-1 are closed and depowered during normal operation [31, 32, 33, 34, 35, 36].

Lacking electrical power, any SILO devices in the control for these valves would have no effect on valve position. Since these valves can be credited for remaining closed following a seismic event, analysis of the valve controls for 1RH8701A-1, 1RH8702B-2, 2RH8701A-1, and 2RH8702B-2 is unnecessary.

Process Sampling Valves Hot Leg Loop M Sample Line Selector Valves 1PS9351A/B, 2PS9351A/B, Pressurizer Steam Sample Selector Valves 1PS9350A, 2PS9350A, Pressurizer Liquid Sample Selector Valves 1PS9350B, 2PS9350B, Cold Leg Loop 1/2/3/4 Sample Line Selector Valves 1PS9358A/B/C/D, 2PS9351A/B/C/D Electrical control for the solenoid-operated pilot valves is via a rugged hand control switch and permissive relay. The MID indicates these valves are normally closed [37, 38, 39], and in this position the (rugged) hand control switch is normally open and blocks the effect of chatter in the series permissive relay. There are no other chatter sensitive contact devices involved in the control of these valves [40, 41, 42, 43].

Page 7 of 75

15C0346-RPT-002, Rev. 0 Correspondence No.: RS-16-175 Loop Sample Line Isolation Valves 1PS9356A, 2PS9356A, Pressurizer Steam Sample Isolation Valves 1PS9354A, 2PS9354A, Pressurizer Liquid Sample Isolation Valves 1PS9355A, 2PS9355A Electrical control for the solenoid-operated pilot valves is via a rugged hand control switch and permissive relay. These valves are shown normally closed on the MID [37, 38, 39]. The only chatter sensitive device in the control circuit is the containment isolation permissive relay.

When the valve is closed the valve position switch contacts are open and block the effect of chatter in the relay. There are no other chatter sensitive contact devices involved in the control of these valves [44, 45, 46, 47].

2.3 REACTOR VESSEL PRESSURE CONTROL The reactor vessel pressure control function is identified as a key function in Reference [8] to be considered in the High Frequency Confirmation. The same report also states that "required post event pressure control is typically provided by passive devices" and that "no specific high frequency component chatter review is required for this function."

2.4 CORE COOLING The core cooling systems were reviewed for contact control devices in seal-in and lockout circuits that would prevent at least a single train of non-AC power driven decay heat removal from functioning. For BYR, the credited decay heat removal system is the Diesel Driven Auxiliary Feedwater (DDAFW) Pump.

The selection of contact devices for the Diesel Driven Auxiliary Feedwater (DDAF) Pump was based on the premise that DDAF operation is desired, thus any SILO which would lead to DDAF operation is beneficial and thus does not meet the criteria for selection [17, 18]. Only contact devices which could render the DDAF system inoperable were considered.

Any chatter which could de-energize the normally-energized Engine Failure Lockout Relay K12 would prevent engine start [19, 20]. The lockout relay itself does not seal in, however the relays with contacts in K12`s coil circuit do. The Overcrank Relay K7, High Water Temperature Relay K8, Overspeed Relay K9, and Low Lube Oil Pressure Relay K10 are normally energized and sealed-in. Chatter in the seal-in contacts of K7, K8, K9, K10, or in the contacts of the Overcrank Timer Relay K4 (input to K7), High Water Temperature Switch 1TSH-AF147 (input to K8), Speed Switch lSS-AF8002 (input to K9), Low Oil Pressure Time Delay Relay K11 (input to K10), could trip the lockout relay and prevent engine start. The time delay associated with K4 and K11 prevents chatter in their coil circuits from affecting engine start. It is presumed that pump suction pressure is above the reset pressure setting of 1PSL-AF055 and therefore chatter in this pressure switch and the Low Suction Pressure Timer Relay K6 have only a temporary effect on engine start and thus do not meet selection criteria.

2.5 AC/DC POWER SUPPORT SYSTEMS The AC and DC power support systems were reviewed for contact control devices in seal-in and lockout circuits that prevent the availability of DC and AC power sources. The following AC and DC power support systems were reviewed:

• Emergency Diesel Generators,

• Battery Chargers and Inverters, Page 8 of 75

15C0346-RPT-002, Rev. 0 Correspondence No.: RS-16-175

• EDG Ancillary Systems, and

• Switchgear, Load Centers, and MCCs.

Electrical power, especially DC, is necessary to support achieving and maintaining a stable plant condition following a seismic event. DC power relies on the availability of AC power to recharge the batteries. The availability of AC power is dependent upon the Emergency Diesel Generators and their ancillary support systems. EPRI 3002004396 [8] requires confirmation that the supply of emergency power is not challenged by a SILO device. The tripping of lockout devices or ,

circuit breakers is expected to require some level of diagnosis to determine if the trip was spurious due to contact chatter or in response to an actual system fault. The actions taken to diagnose the fault condition could substantially delay the restoration of emergency power.

In order to ensure contact chatter cannot compromise the emergency power system, control circuits were analyzed for the Emergency Diesel Generators (EDG), Battery Chargers, Vital AC Inverters, and Switchgear/Load Centers/MCCs as necessary to distribute power from the EDGs to the Battery Chargers and EDG Ancillary Systems. General information on the arrangement of safety-related AC and DC systems, as well as operation of the EDGs, was obtained from the BYR UFSAR [48]. BYR has four (4) EDGs which provide emergency power for their two units. Each unit has two (2) divisions of Class 1E loads with one EDG for each division [48, pp. 8.3-8]. The overall power distribution, both AC and DC, is shown on the Station One-Line Diagram [49].

The analysis considers the reactor is operating at power with no equipment failures or LOCA prior to the seismic event. The Emergency Diesel Generators are not operating but are available. The seismic event is presumed to cause a Loss of Offsite Power (LOOP) and a normal reactor SCRAM.

In response to bus under voltage relaying detecting the LOOP, the Class 1E control systems must automatically shed loads, start the EDGs, and sequentially load the diesel generators as designed. Ancillary systems required for EDG operation as well as Class 1E battery chargers and inverters must function as necessary. The goal of this analysis is to identify any vulnerable contact devices which could chatter during the seismic event, seal-in or lock-out, and prevent these systems from performing their intended safety-related function of supplying electrical power during the LOOP.

The following sections contain a description of the analysis for each element of the AC/DC Support Systems. Contact devices are identified by description in this narrative and apply to all divisions.

Emergency Diesel Generators The analysis of the Emergency Diesel Generators, DG1A, DG113, DG2A, DG213, is divided into two sections, generator protective relaying and diesel engine control. General descriptions of these systems and controls appear in the UFSAR [48, pp. 8.3-8].

Generator Protective Relaying The control circuits for the DG1A circuit breaker [50] include ESF Bus Lockout Relays 486-1412 (Normal Feed), 486-1413 (EDG Feed), and 486-1414X (Reserve Feed). If any of these lockout relays are tripped the EDG breaker will not close automatically during the LOOP. Bus Lockout Relay 486-1412 may be tripped by chatter in Phase Overcurrent Relays PR30A-451 and PR30C-451 and Ground Overcurrent Protective Relay PR31-451N [51]. Bus Lockout Relay 486-1413 is tripped by a solid-state differential relay (non-vulnerable) on the EDG breaker[50]. Bus Lockout Page 9 of 75

15C0346-RPT-002, Rev. 0 Correspondence No.: RS-16-175 Relay 486-1414X may be tripped by chatter in Phase Overcurrent Relays PR27A-451 and PR27C-451 and Ground Overcurrent Protective Relay PR28-451N [52].

The control circuits for the other three EDG circuit breakers are identical in design and sensitive to chatter in their equivalent devices: DG1B: 486-1422, 486-1423, 486-1424X, PR33A-451, PR33C-451, PR34-451N, PR30A-451 PR30C-451 and PR31-451N [53, 54, 55]; DG2A: 486-2412, 486-2413,486-2414, PR9A-451, PR9C-451, PR10-451N, PR13A-451 PR13C-451 and PR14-451N

[56, 57, 58]; DG213: 486-2422, 486-2423, 486-2424, PR7A-451, PR7C-451, PR8-451N, PR3A-451 PR3C-451 and PR4-451N [59, 60, 61].

Diesel Engine Control Chatter analysis for the diesel engine control was performed on the start and shutdown circuits of each EDG [62, 63, 64, 65, 66, 67] (DG1A), [68, 69, 70, 71, 72, 73] (DG1B), [74, 75, 76, 77, 78, 79] (DG2A), [80, 81, 82, 83, 84, 85] (DG2B) using the description of operation [86, 87, 88, 89],

legends [90, 91, 92, 93], and switch development documents [94, 95, 96, 97] as necessary. Two conditions were considered for EDG Start, Emergency Start in response to a true LOOP, and Manual Start as a defense-in-depth response to situations where a bus undervoltage trip has not occurred but offsite power may be considered unreliable after a seismic event (e.g. brownout).

SILO devices that only affect Manual Start availability are being considered based on the discussion below.

It is conservatively assumed that manual start of the EDGs may be desired in the absence of a LOOP-induced emergency start. SILO devices which may block manual start have been identified herein.

The SILO devices which may block EDG Emergency Start in response to a LOOP are the Generator Differential Shutdown Repeater Relays 87G1X and 87G2X, and Engine Overspeed Relays 12X1 and 12X2. 87G1X and 87G2X are both controlled by 486-1413 (already covered).

12X1 and 12X2 are controlled by 1PS-DG251A, 1PS-DG252A, and 1PS-DG108A. Chatter in any of these devices could prevent EDG Emergency Start.

In addition to the devices which could prevent Emergency Start, Manual Start may be blocked by the normally-energized Unit Shutdown Relay 86521. Chatter of the seal-in contact of 8652, or of the contacts of relays within the coil circuits of this relay, may prevent EDG manual start.

Chatter in any other device in the start control circuit would only have a transient effect, delaying start by, at most, the period of strong shaking.

The Unit Shutdown Relay is normally energized and sealed-in. This relay is controlled by the Engine Shutdown Relay 86E, Generator Shutdown Relay 86G, Generator Differential Shutdown Repeater Relays 87G1X and 87G2X, Engine Overspeed Shutdown Relays 12X1 and 12X2, and Incomplete Starting Sequence Relay 48. Chatter in the contacts of these auxiliary relays may cause tripping of the engine shutdown relay. Once tripped this relay would need to be manually reset.

The Engine Shutdown Relay 86E is controlled by the Engine Lube Oil Low Pressure Shutdown Repeater Relay 63QELX, Turbo Low Lube Oil Pressure Shutdown Repeater Relay 63QTLX, Main and Connecting Rod High Bearing Temperature Shutdown Repeater Relay 26MBHTX, Turbo Thrust Bearing Failure Shutdown Repeater Relay 38TBFX, Jacket Water High Temperature Shutdown Repeater Relay 26JWSX, and Crankcase High Pressure Repeater Relay 63CX. Engine 1 Note that the repeater (slave) relay 8651 does not seal-in on its own; it merely mimics the state of 86S2.

I5CO346-RPT-OO2, Rev. O Correspondence No.:RS-IG-175 trips (other than ) are blocked when the diesel engine is not running bv powering the associated auxiliary relay coil circuits via steering diodes. This design feature acts on the coils of these auxiliary relays, however the contacts of these relays are active in the engine fault circuits; and thus chatter ln these auxiliary relays could prevent EOG manual start.

Generator Shutdown Relay 86G is controlled by Generator Overcurrent Relay 51X, Generator Neutral Ground Voltage Auxiliary Relay59GX, Loss of Field Auxiliary Relay 40X, Reverse Power Auxiliary Relay 32X, and Under Frequency Auxiliary Relay 81UX. Generator faults are blocked when the EDG circuit breaker is open (the normal condition at the time of the seismic event) by depovverlng the coil circuits of these auxiliary relays. For this reason, chatter of the protection relays ln these coil circuits would have no effect.

The Incomplete Starting Sequence Relay 4Mia normally energized and sealed-ln. Chatter lnthe Cranking Limit Time Delay Relay 62CL could break the seal-in and prevent EDG manual start.

Other devices in the coil circuit of relay 48 are closed and arranged in parallel. This arrangement blocks the effect of chatter ln any one of these other devices.

Note the device identifiers mentioned here are identical on all EDGs with the exception of the EOG Bus Lockout Relay: 408-14l3 for OGI/;488-1423 for DG18;4B6-2413 for OG2A; and 488-242S for DG2B; and ovenspeed switches: IP3-OG25lA,1PS-OG252A^ and 1PS-OGlO8A for DG1/<<

IPS-DG25IB,IPS-DG2528, and 1PS-DG1O8B for DG18;2PS-DG251A^2PS-OG252A^ and 2PS-OG1O8A for DG2A; and 2PS-OG25lQ,2PS-OG252B, and 29S-OGIO8B for DG2B.

Battery Charaers Chatter analysis on the battery chargers was performed using information from the UFSAR [48]

as well es plant schematic diagrams [9@,99,1OO,2Ol,lO2,1O3]. Each battery charger has ahigh voltage shutdown circuit [48, pp. 8.3-46] which is intended to protect the batteries and DC loads from output overuoltage due to charger failure. The high voltage shutdown circuit has an output relay IDCO3E-DSH-K1orIDCO4E'OSH-K1(2DCO3E'DDH-Nlor2DCD4E'DSH-K1),which shunt-trips the AC input circuit breaker, shutting the charger down. Chatter ln the contacts of these output relays may disable the battery chargers, and for this reason meet the selection criteria.

The battery chargers for the Diesel Driven Auxiliary Feedvvater Pump also have an ovcrvo/tage relay, IAF0IEA-1-D3H-KI or 1AFOlE8-I-D5H-KI (2AF01EA-1-OSH-K1 or 2AFOlEB-1-D5H-KI), that may shutdown these chargers [17, 29, 104, 18, 20, 105].

Static Inverters Bus Reference 111 106 112 107,108.109,110 113 111 114 112,113,114,115 211 116 212 117 213 118 214 119 EDG Ancillary Systems In order to start and operate the Emergency Diesel Generators require a number of components and systems. For the purpose of identifying electrical contact devices, only systems and components which are electrically controlled are analyzed. Information in the UFSAR [48] was used as appropriate for this analysis.

Starting Air Based on Diesel Generator availability as an initial condition the passive air reservoirs are presumed pressurized and the only active components in this system required to operate are the air start solenoids [48, pp. 9.5-21], which are covered under the EDG engine control analysis above.

Combustion Air Intake and Exhaust The combustion air intake and exhaust for the Diesel Generators are passive systems [48, pp.

9.5-29, 120, 121, 122, 123] which do not rely on electrical control.

Lube Oil The Diesel Generators utilize engine-driven mechanical lubrication oil pumps [48, pp. 9.5-231 which do not rely on electrical control.

Fuel Oil The Diesel Generators utilize engine-driven mechanical pumps to supply fuel oil to the engines from the day tanks [48, pp. 9.5-6]. The day tanks are re-supplied using AC-powered Diesel Oil Transfer Pumps [124, 125, 120, 121, 122, 123]. Chatter analysis of the control circuits for the electrically-powered transfer pumps [126,127, 128, 129] concluded they do not include SILO devices. The mechanical pumps do not rely on electrical control.

Correspondence No.: RS-16-175 Cooling Wate The Diesel Generator Cooling Water System is described ln the UFSAR[48, pp. 9.5-l5]. This system consists of two cooling loops, jacket water and Essential Service Water (E8VV). Engine driven pumps are credited for jacket water when the engine lsoperating. These mechanical pumps do not nsly on electrical control. The electric jacket water pump is only used during shutdown periods and ls thus not included ln this analysis.

Four ESW pumps, 1A, 113, 2A, and 213, provide cooling water to the heat exchangers associated with the four EDGs[I3[,l31,232,188,134,l35]. ln automatic mode these pumps are started via a sequencing signal following EDG start. Chatter analysis of the EDG start signal lsincluded ln the Emergency Diesel Generator section above. A chatter analysis of the E3W pump circuit breaker control circuits [136,l37,I38,139] indicates the Low Suction Pressure Relays S%2AXor SX1B%; the Phase Overcurnant Relays PR3A-45[/451,PR3C-45O/45I,PA4/-45O/451,orPR4C-4SO/4S1(U2:PA3GA-450/451,PRS6C-450/45I,PRl8A-45O/451,orPRl3C-45O/45]); and the Ground Fault Relays PR4-45ONorPR5-45ON/U2:PR37-45DNorPR14-45ON\ all could prevent automatic (sequendal) breaker closure following the seismic event.

ESW valves necessary for EDG cooling are either locked out, depowered, or, in the case of valves 1S%IG9A and lSXI8BB(3S%I69A and 2S%1698),do not contain SILO devices [14O,141].

Ventilation The Diesel Generator Enclosure Ventilation System is described in Section 9.4.5.2 of the UF3AR

[48, pp. 9.4-25]. Ventilation for each Diesel Generator Enclosure is provided via intake and exhaust fans [242,l48]. ln automatic mode the intake fans are started via the EDG Start Signal or high room temperature. Chatter analysis ofthe EOG start signal la included lnthe Emergency Diesel Generator section above. Apart from SILO devices identified for the EDG start signal, chatter analysis of the control circuits for the intake fans [I44,145,l46,I47,I48,149,15O,151]

concluded they do not include SILO devices. Contact chatter on pressure switch 2PO5-VOO44 (2PDS-VD044) may set the latching relay VD01CAX and interrupt fan operation, however a timing circuit would eutornotloal{y reset this relay after 58seconds. Since this effect is transient only, lt does not meet the selection criteria.

Contact chatter on pressure switches 1PDS-VD103 or 1PDS-VD105 (2PDS-VD103 or 2PDS-VD105) may set latching relays VD03CAX or VD03CBX, respectively, which would lock out the exhaust fans and require a manual reset [152,153].

Switchaear, Load Centers, and MM Power distribution from the EDGs to the necessary electrical loads (Battery Chargers, Inverters, Fuel Oll Pumps, and EOG Ventilation Fans) was traced to identify any SILO devices which could lead to a circuit breaker trip and interruption in power. This effort excluded control circuits for the EDG circuit breakers, which are covered in the Emergency Diesel Generator section above, and the ESW Pump breakers which are covered in the EDG Ancillary Systems section above, as well as component-specific contactors and their control devices, which are covered in the analysis of each component above. Those medium- and low-voltage circuit breakers ln4I6OV ESF Busses and 48OVAC Load Centers [154,155,15G,157] supplying power to loads identified ln this section (battery chargers, EDG ancillary systems, etc.) have been identified for evaluation:

Per the UFSAR [48, pp. 8.3-44], DC Distribution [170, 171, 172, 173, 174, 175, 176, 177] uses Molded-Case Circuit Breakers (MCCBs) which are seismically rugged [4, pp. 2-11]. MCCBs in the low voltage Motor Control Center Buckets [158, 159, 160, 161, 162, 163] (U1), [164, 165, 166, 167, 168, 169] (U2), as well as the 120VAC Vital Instrument Buses [178, 179, 180, 181, 182, 183, 184, 185] were considered rugged as well. The only circuit breakers affected by external contact devices not already mentioned were those that distribute power from the 4160V ESF Busses to the 4160/480V step-down transformers. A chatter analysis of the control circuits for these circuit breakers [186, 187, 188, 189] indicates the transformer primary phase overcurrent relays PR37A-450/451, PR37B-450/451, PR37C-450/451, PR28A-450/451, PR28B-450/451, or PR28C-450/451(U2: PR3A-450/451, PR3B-450/451, PR3C-450/451, PR11A-450/451, PR1113-450/451, or PR11C-450/451); primary and secondary ground fault relays PR38-450N, PR29-450N, or PR1-351N (U2: PR4-450N, PR12-450N, or PR1-351N); and lockout relays 486-1415X or 486-1425X (U2: 486-2415X or 486-2425X) all could trip the transformer primary circuit breaker following the seismic event.

SUMMARY

OF SELECTED COMPONENTS The investigation of high-frequency contact devices as described above was performed in Ref.

[191]. A list of the contact devices requiring a high frequency confirmation is provided in Appendix B, Table B-1. The identified devices are evaluated in Ref. [190] per the methodology/description of Section 3 and 4. Results are presented in Section 5 and Table B-1.

15C0346-RPT-002, Rev. 0 Correspondence No.: RS-16-175 3 Seismic Evaluation 3.1 HORIZONTAL SEISMIC DEMAND Per Reference [8], Sect. 4.3, the basis for calculating high-frequency seismic demand on the subject components in the horizontal direction is the BYR horizontal ground motion response spectrum (GMRS), which was generated as part of the BYR Seismic Hazard and Screening Report

[4] submitted to the NRC on March 31, 2014, and accepted by the NRC on February 17, 2016

[14].

It is noted in Reference [8] 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 Ref. [8], "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."

The applicable buildings at BYR are founded on rock; therefore, the Control Point GMRS is representative of the input at the building foundation.

The horizontal GMRS values are provided in Table 3-2.

3.2 VERTICAL SEISMIC DEMAND As described in Section 3.2 of Reference. [8], the horizontal GMRS and site soil conditions are used to calculate the vertical GMRS (VGMRS), 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. [4], Table 2.3.2-1 and reproduced below in Table 3-1.

• The time for a shear wave to travel through each soil layer is calculated by dividing the layer depth (di) 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 (F[d,/Vsi]).

• 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 = (30m)/F[d,/Vsi].

• Note: The shear wave velocity is calculated based on time it takes for the shear wave to travel 30.78m (101.0ft) instead of 30m (98.43ft). This small change in travel distance will have no impact on identifying soil class type.

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 [8],

Table 3-1. Based on the PGA of 0.270g and the shear wave velocity of 3145ft/s, the site soil class is C-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

[8], 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 [8],

Table 3-2 values are constant between 0.11-lz and 20Hz.

The V/H ratios and VGMRS 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 BYR.

15C0346-RPT-002, Rev. 0 Correspondence No.: RS-16-175 3.3 COMPONENT HORIZONTAL SEISMIC DEMAND Per Reference [8] the peak horizontal acceleration is amplified using the following 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 AFB to account for seismic amplification within the host equipment (cabinet, switchgear, motor control center, etc.)

The in-structure amplification factor AFsH is derived from Figure 4-3 in Reference [8]. The in-cabinet horizontal amplification factor, AFB is associated with a given type of cabinet construction. The three general cabinet types are identified in Reference [8] and Appendix I of EPRI NP-7148 [13] assuming 5% in-cabinet response spectrum damping. EPRI NP-7148 [13]

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 benchboard 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 Appendix B) can be categorized into one of the in-cabinet amplification categories in Reference [8] as follows:

• BYR Motor Control Centers are typical motor control center cabinets consisting of a lineup of several interconnected sections. Each section is a relatively narrow cabinet structure with height-to-depth ratios of about 4.5 that allow the cabinet framing to be efficiently used in flexure for the dynamic response loading, primarily in the front-to-back direction. This results in higher frame stresses and hence more damping which lowers the cabinet response. In addition, the subject components are not located on large unstiffened panels that could exhibit high local amplifications. These cabinets qualify as low amplification cabinets.

• BYR Switchgear cabinets are large cabinets consisting of a lineup of several interconnected sections typical of the high amplification cabinet category. Each section is a wide box-type structure with height-to-depth ratios of about 1.5 and may include wide stiffened panels. This results in lower stresses and hence less damping which increases the enclosure response. Components can be mounted on the wide panels, which results in the higher in-cabinet amplification factors.

• BYR Control cabinets are in a lineup of several interconnected sections with moderate width. Each section consists of structures with height-to-depth ratios of about 3 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.

15C0346-RPT-002, Rev. 0 Correspondence No.: RS-16-175 3.4 COMPONENT VERTICAL SEISMIC DEMAND The component vertical demand is determined using the peak acceleration of the VGMRS 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 AFB 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 [8]. The in-cabinet vertical amplification factor, AFB is derived in Reference [8] and is 4.7 for all cabinet types.

. Ito0" Per Reference [8], 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:

(I)Ka contact device was tested as part of the EP0High Frequency Testing program [7],

then the component seismic capacity from this program is used.

(2) Ifa contact device was not tested os part of[7], then one or more of the following means to determine the component capacity were used:

(a) Device-specific seismic test reports (either from the station or from the SQURTS testing program.

(b) Generic Equipment Ruggedness Spectra (GERS) capacities per [9], [10], [11], and kj Assembly (e.g. electrical cabinet) tests where the component functional performance was monitored.

Work the PGA and shear wave velocity with Ref. 1.1, Table 3-1 to determine the soil class of the site. Based on the PGA of 0.2708 and shear wave velocity of 3145ft/sec at BYR, the site soil class is conservatively taken as C-Hard.

Work the site soil class with Ref. 1.1, Table 3-2 to determine the mean vertical vs. horizontal GMRS ratios (V/H) at each spectral frequency. Multiplythe V/H ratio at each frequency between 15Hz and 40Hz by the corresponding horizontal GMRS acceleration at each frequency between 15Hz and 40Hz to calculate the vertical GMRS.

Check: MD 10/5/2016 8 ANALYSIS (cont'd) 8.3 High-Frequency Seismic Capacity for Ref. 1.1 Relays A sample calculation for the high-frequency seismic capacity of 1AF01J-K4 and 1AF011-K10 relay components are presented here. A table that calculates the high-frequency seismic capacities for all of the Ref. 1.1 subject relays listed in Section 1, Table 1.1 of this ca Icu lation is provided in Attachment A of this calculation.

8.3.1 Seismic Test Capacity The high frequency seismic capacity of a relay can be determined from the Ref. 1.2 high-frequency testing program or other broad banded low frequency capacity data such as the Generic Equipment Ruggedness Spectra (GERS). Per Ref. 1.1, Sect. 4.5.2, a conservative estimate of the high-frequency (i.e., 20Hz to 40Hz) capacity can be made by extending the low frequency GERS capacity into the high frequency range to a roll off frequency of about 40Hz. Therefore, if the high frequency capacity was not available for a component, a SAT value equal to the GERS spectral acceleration from 4 to 16 Hz could be used.

For the relay component 1AF01J-K4 (Model #: E70120EL) and 1AF01J-K10 (Model #: KHS17D11), the GERS spectral acceleration from Ref. 1.3 is used as the seismic test capacity.

Therefore for the relay components 1AF01J-K4 and 1AF01J-K10 there is no spectral acceleration increase.
