1.0 INTRODUCTION

1.1 PURPOSE The purpose of this attachment is to provide information requested by the NRC in its March 12, 2012 10 CFR 50.54(f) letter issued to all power reactor licensees and holders of construction permits in active or deferred status (Reference 1). Specifically, this attachment provides the results of the High Frequency Confirmation required by Item (4), Enclosure 1, Recommendation 2.1: Seismic, of the letter.

The High Frequency Confirmation evaluation undertaken for Millstone Power Station Unit 2 (MPS2) used the methodologies in EPRI Report 3002004396, "High Frequency Program, Application Guidance for Functional Confirmation and Fragility Evaluation" (Reference 8) as described herein.

A summary of the High Frequency Confirmation evaluations and results are provided below.

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 (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 10 CFR 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(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 Report 1025287, "Seismic Evaluation Guidance: Screening, Prioritization and Implementation Details (SPID) for the resolution of Fukushima Near-Term Task Force Recommendation 2.1: Seismic" (Reference 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.

Serial No.16-455 Docket Nos. 50-336/423 Attachment 1 MPS2 HF Sensitive Equipment Functional Confirmation Page 2 of 25 Subsequent guidance for performing a High Frequency Confirmation was provided in EPRI Report 3002004396, "High Frequency Program, Application Guidance for Functional Confirmation and Fragility Evaluation," (Reference 8) and was endorsed by the NRC in a letter dated September 17, 2015 (Reference 3). Final screening identifying plants needing to perform a High Frequency Confirmation was provided by NRC in a letter dated October 27, 2015 (Reference 2).

On March 31, 2014, Millstone Power Station submitted a reevaluated seismic hazard to the NRC as a part of the Seismic Hazard and Screening Report (Reference 4). By letter dated October 27, 2015 (Reference 2), the NRC transmitted the results of the screening and prioritization review of the seismic hazards reevaluation.

The reevaluated seismic hazard was developed in order to provide the information requested by the NRC in Reference 1 and does not constitute a new or supplemental seismic design or licensing basis for MPS2. As such, the conclusions of the High Frequency Confirmation review do not result in a challenge to the design basis function of any plant structures, systems, or components important to safety.

1.3 APPROACH EPRI Report 3002004396 (Reference 8) is used for the MPS2 engineering evaluations described in this attachment. 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 attachment:

  • 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 high-frequency evaluations for subject components
  • Summary of Results 1.4 PLANT SCREENING MPS2 submitted the reevaluated seismic hazard information, including the GMRS, to the NRC on March 31, 2014 (Reference 4). In letters dated December 15, 2015 and March 15, 2016 (References 12 and 13, respectively), the NRC staff concluded that the submitted GMRS adequately characterizes the reevaluated seismic hazard for the MPS site.

The NRC final screening determination letter (Reference 2) concluded that the MPS2 GMRS to SSE comparison resulted in a need to perform a High Frequency Confirmation in accordance

Serial No.16-455 Docket Nos. 50-336/423 Attachment 1 MPS2 HF Sensitive Equipment Functional Confirmation Page 3 of 25 with the screening criteria in the SPID (Reference 6).

1.5 INITIAL CONDITIONS For the purposes of this High Frequency Confirmation review, the plant is assumed to be operating normally prior to the occurrence of the severe seismic event with offsite power sources available. The seismic event was presumed to cause a Loss of Offsite Power (LOOP) and a normal reactor trip.

2.0 SELECTION OF COMPONENTS FOR HIGH-FREQUENCY SCREENING The fundamental objective of the high-frequency confirmation review was to determine whether the occurrence of a seismic event could cause critical equipment to fail to perform as necessary.

An optimized evaluation process was applied that focused 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 coolant system 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 and support systems).

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

For each function, a review was performed to identify plant equipment supporting the function.

The control circuit schematic diagrams for this equipment were then reviewed using the guidance from EPRI NP-7148 (Reference 11) and EPRI Report 3002004396 (Reference 8) to determine whether seismic-induced contact chatter could result in seal-in or lockout (SILO) conditions that could have an adverse impact on the equipment capability to support key plant safety functions. From this review, a list of contact control devices for which contact chatter could result in SILO conditions was identified. These devices (termed "relays" for the purposes of this evaluation) were further evaluated for seismic capacity margin, as described in Sections 3 and 4.

Serial No.16-455 Docket Nos. 50-336/423 Attachment 1 MPS2 HF Sensitive Equipment Functional Confirmation Page 4 of 25 2.1 REACTOR TRIP/SCRAM Consistent with the guidance in Reference 8, the design requirements for reactor trip systems preclude the application of seal-in or lockout circuits that prevent reactor trip/SCRAM functions and no high-frequency component chatter review is necessary for this function.

2.2 REACTOR COOLANT SYSTEM INVENTORY CONTROL The reactor coolant system inventory control systems were reviewed to identify components .

that could be susceptible to adverse operation due to contact control devices in SILO circuits that could create loss of coolant-type events, such as inadvertent opening of a pressurizer power-operated relief valve (PORV).

The following components were identified for control circuit review for SILO conditions:

  • Pressurizer PORVs 2.3 REACTOR COOLANT SYSTEM PRESSURE CONTROL Consistent with the guidance in Reference 8, no specific high-frequency component chatter review is required for this function.

2.4 CORE COOLING The core cooling systems were reviewed to identify components that could be susceptible to adverse operation due to contact control devices in SILO circuits that would prevent accomplishment of the core cooling function. The intent of the review was to ensure at least a single train of non-AC power driven. decay heat removal capability was maintained (e.g.,

auxiliary feedwater flow from at least one pump to at least one steam generator).

The following components were identified for control circuit review for SILO conditions:

  • Atmospheric Steam Dump Valves
  • Turbine-driven AFW Pump Steam Supply Valves
  • Turbine-driven AFW Pump Trip-Throttle Valve
  • Turbine-driven AFW Pump 2.5 AC/DC POWER SUPPORT SYSTEMS The AC and DC power support systems were reviewed to identify components that could be susceptible to adverse operation due to contact control devices in SILO circuits that prevent the availability of DC and/or AC power sources. The following AC and DC power support systems

Serial No.16-455 Docket Nos. 50-336/423 Attachment 1 MPS2 HF Sensitive Equipment Functional Confirmation Page 5 of 25 were reviewed:

  • EOG Support Systems and associated Switchgear, Load Centers, and MCCs,
  • Battery Chargers and Inverters,
  • Vital 125vdc and 120vac Distribution The analysis considered the reactor operating normally at power with no equipment failures prior to the seismic event. The EDGs are not operating, but are available. The seismic event was presumed to cause a Loss of Offsite Power (LOOP) and a normal reactor trip.

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 EOG operation, as well as Class 1E battery chargers and inverters, must function as necessary.

The following components were identified for control circuit review for SILO conditions:

  • 4kV Emergency Bus Feeder and Bus Tie Breakers (Emergency and Offsite sources)
  • 480v Emergency Bus Feeder and Tie Breakers
  • 4kV I 480v Emergency Bus Transformers and 4kV Supply Breakers
  • 4kV Emergency Bus Load Breakers to Service Water, AFW, High Pressure Safety Injection, Low Pressure Safety Injection, Containment Spray and Reactor Building Closed Cooling Water Pumps
  • 480v Emergency Bus Load Breakers to 125vdc Battery Chargers, various MCCs, and Load Centers
  • 125vdc Batteries, DC Susses, Battery Chargers, and Distribution System Components
  • 120vac Vital Inverters and Distribution System Components
  • EOG Air Start System Valves
  • EOG Room Ventilation Fans and Dampers

SUMMARY

OF SELECTED COMPONENTS A list of the contact devices requiring a high-frequency confirmation is provided in Appendix 1.

3.0 SEISMIC DEMAND ESTIMATE The high-frequency functional confirmation process for the relays subject to the potential for seismic-induced contact chatter requires the mounting point seismic demand to be determined, which requires the development of in-structure seismic demand based on the GMRS input and the in-cabinet amplification of the in-structure floor motion at the location of the electrical cabinet housing the relay.

The calculation of in-structure response typically requires the development of a foundation input response spectrum (FIRS) and dynamic analysis of the structure. MPS2 has not developed these inputs from the GMRS for plant structures. Therefore, consistent with the guidance in Reference 8, Section 4.3, the in-structure response for buildings and floor elevations where subject relays are located was estimated as described in subsection 3.1 below.

The mounting point high-frequency seismic demand was determined consistent with the guidance in Reference 8, Sections 4.4 and 4.5, and is described in subsection 3.2 below.

3.1 ESTIMATE OF HIGH FREQUENCY IN-STRUCTURE RESPONSE Per Reference 8, Sect. 4.3, the basis for calculating high-frequency seismic demand in the horizontal direction is the horizontal control point GMRS, which was developed in response to Reference 1 and reported in the MPS Seismic Hazard and Screening Report (Reference 4). As noted in Reference 8, Section 3.3, 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.

MPS is a rock site, and the MPS2 structures of interest for the high-frequency confirmation (Auxiliary Building and Turbine Building) are rock-founded. Therefore, the control point GMRS was the appropriate review level earthquake (RLE) input for the purposes of the high-frequency confirmation.

Serial No.16-455 Docket Nos. 50-336/423 Attachment 1 MPS2 HF Sensitive Equipment Functional Confirmation Page 7 of 25 3.1.1 HORIZONTAL SEISMIC DEMAND The horizontal response structural amplification factor to be applied for estimating the horizontal in-structure seismic demand is provided in Reference 8, Figure 4-3 and is based upon the height of the electrical cabinet (that the relay is mounted within) above the building foundation.

For the MPS2 high-frequency confirmation, this height was taken as the difference between the lowest floor elevation and the floor elevation of the cabinet anchorage.

The horizontal seismic demand was calculated in accordance with Reference 8, Equation 4-1 a:

SAcH =SAGMRS

  • AF SH SAcH is the Spectral Acceleration, Clipped Horizontal (i.e., in-structure [floor] horizontal acceleration).

SAGMRS is the peak GMRS between 15-40Hz. The SAGMRs value is 0.422g from Reference 4.

The horizontal GMRS is plotted in Figure 3-1.

AFsH is the Horizontal Response Structural Amplification Factor from Reference 8, Figure 4-3.

3.1.2 VERTICAL SEISMIC DEMAND The vertical response structural amplification factor to be applied for estimating the vertical in-structure seismic demand is provided in Reference 8, Figure 4-4 and is based upon the height of the electrical cabinet (that the relay is mounted within) above the building foundation. For the MPS2 high-frequency confirmation, this height was taken as the difference between the lowest floor elevation and the floor elevation of the cabinet anchorage.

The vertical seismic demand was calculated in accordance with Reference 8, Equation 4-1 b:

SAcv =SAvGMRS

  • AF sv SAcv is the Spectral Acceleration, Clipped Vertical (in-structure [floor] vertical acceleration).

SAvGMRs is the peak estimated Spectral Acceleration, Vertical GMRS in the 15 to 40Hz frequency range. The peak SAvGMRs is the maximum product of the Vertical-to-Horizontal (V/H) function values and the corresponding horizontal GMRS values between 15 and 40Hz. The GMRS values are from Reference 4. The V/H function is derived from Reference 8, Tables 3-1 and 3-2, utilizing the GMRS peak ground acceleration (PGA) [0.190g] and the shear wave travel time from a depth of 30 meters to the ground surface (Vs30) from Reference 4. For MPS2, the V/H function values are between 0.680 @ 15 Hz and 0.860 @ 40Hz, and are based on the GMRS Horizontal PGA = 0.19g and Vs30 > 1,000 mps corresponding to a site class '8-Hard' per Reference 8, Table 3-2. The maximum product of the V/H function values and the

corresponding GMRS is 0.31 g, which occurs at 40Hz (GMRS 0.36g, V/H 0.86). The GMRS, estimated vertical GMRS (VGMRS), and V/H Ratio values are plotted in Figure 3-1, along with the SSE spectrum.

Serial No.16-455 Docket Nos. 50-336/423 Attachment 1 MPS2 HF Sensitive Equipment Functional Confirmation Page 8 of 25 AFsv is the Vertical Response Structural Amplification Factor from Reference 8, Figure 4-4.

3.2 ESTIMATE OF HIGH FREQUENCY MOUNTING POINT SEISMIC DEMAND The mounting point seismic demand was determined by applying in-cabinet amplification factors to the in-structure demand, as described in Reference 8, Sections 4.4 and 4.5.1.

The in-structure demand was determined as described in Section 3.1 above. The in-cabinet amplification factor is applied to account for the amplification of the structure seismic response at the cabinet anchor points. The in-structure demand (horizontal or vertical) was multiplied by the applicable in-cabinet amplification factor to obtain the mounting point demand.

Horizontal cabinet amplification factors used were:

Motor Control Centers AFc =3.6 Switchgear (flexible panels) AFc =7.2 Control Cabinets (e.g., Control Room electrical panels AFc =4.5 and bench boards, etc.)

Cabinet types were determined based on guidance in EPRI NP-7148, "Procedure for Evaluating Nuclear Power Plant Relay Seismic Functionality" (Reference 11).

The vertical cabinet amplification factor used was AFc = 4.7 for all three cabinet types.

For electrical cabinets/enclosures that did not correspond to the listed cabinet types, in-cabinet amplification factors consistent with the cabinet configuration were used and justified on a case-by-case basis.

The mounting point demand, ICRSc, used in the horizontal and vertical directions for evaluation of the relays, is equal to the product of the clipped in-structure demand and the applicable cabinet amplification factor within the 15 to 40 Hz frequency range, as described in Reference 8, Sections 4.4:

ICRScH =AFcH

  • SAcH ICRScv =AFcv
  • SAcv The cabinet type classification and the mounting point seismic demand are tabulated for each evaluated relay in Appendix 1.

Seismic demand was determined as described in Section 3.0. The deterministic high confidence of low probability of failure (HCLPF) capacity of the relay device was determined in accordance with the guidance of Reference 8, Section 4.5.

4.1 HCLPF COMPONENT CAPACITY The HCLPF capacities of the relays were developed based on the guidance in Reference 8, Section 4.5.2. The effective wide band capacity, TRS , is given by Reference 8, Equation 4-5:

SAT is the Spectral Acceleration, Effective Spectral Test Capacity (Relay Seismic Capacity) for relays as obtained from one of the following sources:

Serial No.16-455 Docket Nos. 50-336/423 Attachment 1 MPS2 HF Sensitive Equipment Functional Confirmation Page 10 of 25

  • EPRI High Frequency Test Program (References 7 and 8)
  • Generic Equipment Ruggedness Spectrum (GERS) (Reference 9 and 10)
  • Seismic Qualification Reporting and Testing Standardization (Reference 14)
  • Site-specific seismic qualification test data Certain relay model numbers identified on the relay list are not explicitly covered by the testing referenced in the list above and a comparison of the relay to other similar relay types having seismic qualification test data (e.g., same manufacturer & same family of relay, similar size, shape, features, construction, etc.) was made in those cases in order to provide a SAT value.

FK is the Conservative Deterministic Failure Margin (CFDM) Knockdown Factor and its value depends on the source of the test value chosen to represent test capacity. FK was obtained from Reference 8, Table 4-2.

FMs is the Multi-axis to Single-axis Correction Factor and is equal to either 1.0 or 1.2 depending on the expected seismic response of the relay enclosure cabinet. The value of FMs was chosen consistent with the guidance from Reference 8, Section 4.5.2.

The effective wide band capacity, along with the source for the device capacity, is tabulated for each evaluated relay in Appendix 1.

4.2 SEISMIC MARGIN EVALUATION The seismic margin to the onset of contact chatter was determined by comparing the HCLPF capacity, TRS, to the mounting point seismic demand, ICRSc, to obtain the capacity/demand ratio:

CID= TRS / ICRSc (C/D is determined for horizontal and vertical directions)

The results of the relay chatter evaluation is tabulated for each evaluated relay in Appendix 1.

Two representative sample relay evaluations are included in Appendix 2.

5.0 CONCLUSION

S 5.1

SUMMARY

OF RESULTS The high-frequency confirmation review was performed consistent with the guidance in EPRI Report 3002004396 (Reference 8). The following results were obtained:

  • 132 essential plant components were selected for detailed review
  • 103 components were selected for relay chatter evaluation (the remaining 29 components are non-electrical, and do not require relay chatter evaluation)
  • 363 relays were identified for the 103 components evaluated for relay chatter

Serial No.16-455 Docket Nos. 50-336/423 Attachment 1 MPS2 HF Sensitive Equipment Functional Confirmation Page 11 of 25

  • 104 relays were identified with the potential to cause SILO conditions and required seismic margin evaluation
  • 101 relays were determined to have adequate seismic margin to chatter (C/D ratio>/= 1)

The high-frequency confirmation review determined there are three relays associated with essential components for which, based on available high-frequency seismic capacity information and the conservatively estimated seismic demand, the seismic capacity is exceeded by the GMRS in-cabinet seismic demand. These relays are identified in the table below. The relays are associated with protection and/or metering for 4kV Emergency Diesel Generator output breakers. The relays are located within the 4kV Emergency Switchgear A3 and A4 cubicles.

Appendix1 Component ID Associated Relay ID(s)

Item No. (Breaker ID) (Switchgear Cubicle location) 6 15G-12U-2 (52-A312) 81 (A312) 15 15G-13U-2 (52-A401) 81 (A401) 18 15G-13U-2 (52-A401) 51V-A, B & C (A401)

Chatter of the relays could cause trip and/or prevent closure of the emergency diesel generator (EOG) output breaker at a time when the EOG is required to provide emergency power to the associated 4kV emergency bus (i.e., LOOP).

Further review of the consequences of potential contact chatter associated with these relays determined that operator action guided by existing emergency response procedures would resolve the condition. As part of the immediate actions, response to a reactor trip, as detailed in the Standard Post Trip Actions Emergency Operating Procedure, EOP-2525, the operator in the main control room is directed to check that vital electrical buses are energized. If the 4kV emergency bus(es) is(are) not energized, the procedure provides the immediate action to confirm that the EOG is running and ensure that the output breaker is closed. As part of this action, if the breaker had not closed, or had tripped open, as a result of 81 (frequency) or 51 (time overcurrent) relay device contact chatter, the operator would manually close the output breaker remotely from the panel in the main control room after confirming appropriate permissives are established (also from the main control room) .. This action would resolve the adverse effect that could result from the relay contact chatter. Since this action would take place within the main control room and is guided by an existing procedure, the action to manually close the EOG output breaker to resolve the potential relay contact chatter consequence is not considered to be an excessive operational burden. In addition, the plant would initially reach safe and stable conditions without emergency AC power.

5.2 CONCLUSION

This attachment provides the information required by Enclosure 1, Recommendation 2.1:

Serial No.16-455 Docket Nos. 50-336/423 Attachment 1 MPS2 HF Sensitive Equipment Functional Confirmation Page 12 of 25 Seismic, Item (4) of the NRC's March 12, 2012 request for information letter (Reference 1).

A high-frequency confirmation review has been performed for MPS2 to determine whether the occurrence of a severe seismic event could cause selected essential equipment to fail to perform as necessary. As a result of this review, it is concluded that accomplishment of the key plant safety functions defined in Reference 8 will not be adversely affected due to relay chatter during a severe seismic event equivalent to the level of the reevaluated seismic hazard for Millstone Power Station Unit 2.

1.0 INTRODUCTION

1.1 PURPOSE The purpose of this attachment is to provide information requested by the NRC in its March 12, 2012 10 CFR 50.54(f) letter issued to all power reactor licensees and holders of construction permits in active or deferred status (Reference 1). Specifically, this attachment provides the results of the High Frequency Confirmation required by Item (4), Enclosure 1, Recommendation 2.1: Seismic, of the letter.

The High Frequency Confirmation evaluation undertaken for MPS Unit 3 (MPS3) used the methodologies in EPRI Report 3002004396, "High Frequency Program, Application Guidance for Functional Confirmation and Fragility Evaluation" (Reference 8) as described herein.

A summary of the High Frequency Confirmation evaluations and results are provided below.

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 (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 NTIF developed a set of recommendations intended to clarify and strengthen the regulatory framework for protection against natural phenomena. Subsequently, the NRC issued a 10 CFR 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 10 CFR 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 Report 1025287, "Seismic Evaluation Guidan~e: Screening, Prioritization and Implementation Details (SPID) for the resolution of Fukushima Near-Term Task Force Recommendation 2.1: Seismic" (Reference 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 guiaance for determining which plants should perform a High Frequency Confirmation and identified the types of components that should be evaluated in the evaluation.

Serial No.16-455 Docket Nos. 50-336/423 Attachment 2 MPS3 HF Sensitive Equipment Functional Confirmation Page 2 of 54 Subsequent guidance for performing a High Frequency Confirmation was provided in EPRI Report 3002004396, "High Frequency Program, Application Guidance for Functional Confirmation and Fragility Evaluation," (Reference 8) and was endorsed by the NRC in a letter dated September 17, 2015 (Reference 3). Final screening identifying plants needing to perform a High Frequency Confirmation was provided by NRC in a letter dated October 27, 2015 (Reference 2).

On March 31, 2014, Millstone Power Station submitted a reevaluated seismic hazard to the NRC as a part of the Seismic Hazard and Screening Report (Reference 4). By letter dated October 27, 2015 (Reference 2), the NRC transmitted the results of. the screening and prioritization review of the seismic hazards reevaluation.

The reevaluated seismic hazard was developed in order to provide the information requested by the NRC in Reference 1 and does not constitute a new or supplemental seismic design or licensing basis for MPS3. As such, the conclusions of the High Frequency Confirmation review do not result in a challenge to the design basis function of any plant structures, systems, or components important to safety.

1.3 APPROACH EPRI Report 3002004396 (Reference 8) was used for the MPS3 engineering evaluations described in this attachment. 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 attachment:

  • 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 high-frequency evaluations for subject components
  • Summary of Results 1.4 PLANT SCREENING MPS3 submitted the reevaluated seismic hazard information, including the GMRS, to the NRC on March 31, 2014 (Reference 4). In letters dated December 15, 2015 and March 15, 2016 (References 12 and 13, respectively), the NRC staff concluded that the submitted GMRS adequately characterizes the reevaluated seismic hazard for the MPS site.

Serial No.16-455 Docket Nos. 50-336/423 Attachment 2 MPS3 HF Sensitive Equipment Functional Confirmation Page 3 of 54 The NRC final screening determination letter (Reference 2) concluded that the MPS3 GMRS to SSE comparison resulted in a need to perform a High Frequency Confirmation in accordance with the screening criteria in the SPID (Reference 6).

1.5 INITIAL CONDITIONS For the purposes of this High Frequency Confirmation review, the plant is assumed to be operating normally prior to the occurrence of the severe seismic event with offsite power sources available. The seismic event was presumed to cause a Loss of Offsite Power (LOOP) and a normal reactor trip.

2.0 SELECTION OF COMPONENTS FOR HIGH-FREQUENCY SCREENING The fundamental objective of the high-frequency confirmation review was to determine whether the occurrence of a seismic event could cause critical equipment to fail to perform as necessary.

An optimized evaluation process was applied that focused 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 coolant system 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 and support systems).

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

For each function, a review was performed to identify plant equipment supporting the function.

The control circuit schematic diagrams for this equipment were then reviewed using the guidance from EPRI NP-7148 (Reference 11) and EPRI Report 3002004396 (Reference 8) to determine whether seismic-induced contact chatter could result in seal-in or loc~out (SILO) conditions that could have an adverse impact on the equipment capability to support key plant safety functions. From this review, a list of contact control devices for which contact chatter could result in SILO conditions was identified. These devices (termed "relays" for the purposes of this evaluation) were further evaluated for seismic capacity margin, as described in Sections 3 and 4.

Serial No.16-455 Docket Nos. 50-336/423 Attachment 2 MPS3 HF Sensitive Equipment Functional Confirmation Page 4 of 54 2.1 REACTOR TRIP/SCRAM Consistent with the guidance in Reference 8, the design requirements for reactor trip systems preclude the application of seal-in or lockout circuits that prevent reactor trip/SCRAM functions and no high-frequency component chatter review is necessary for this function.

2.2 REACTOR COOLANT SYSTEM INVENTORY CONTROL The reactor coolant system inventory control systems were reviewed to identify components that could be susceptible to adverse operation due to contact control devices in SILO circuits that could create loss of coolant-type events, such as inadvertent opening of a pressurizer power-operated relief valve (PORV).

The following components were identified for control circuit review for SILO conditions:

  • Pressurizer PORVs 2.3 REACTOR COOLANT SYSTEM PRESSURE CONTROL Consistent with the guidance in Reference 8, no specific high-frequency component chatter review is required for this function.

2.4 CORE COOLING The core cooling systems were reviewed to identify components that could be susceptible to adverse operation due to contact control devices in SILO circuits that would prevent accomplishment of the core cooling function. The intent of the review was to ensure at least a single train of non-AC power driven decay heat removal capability was maintained (e.g.,

auxiliary feedwater flow from at least one pump to at least one steam generator).

The following components were identified for control circuit review for SILO conditions:

  • Atmospheric Steam Dump Valves
  • Turbine-driven AFW Pump Steam Supply Valves
  • Turbine-driven AFW Pump Trip-Throttle Valve
  • Turbine-driven AFW Pump 2.5 AC/DC POWER SUPPORT SYSTEMS The AC and DC power support systems were reviewed to identify components that could be

Serial No.16-455 Docket Nos. 50-336/423 Attachment 2 MPS3 HF Sensitive Equipment Functional Confirmation Page 5 of 54 susceptible to adverse operation due to contact control devices in SILO circuits that prevent the availability of DC and/or AC power sources. The following AC and DC power support systems were reviewed:

  • EOG Support Systems and associated Switchgear, Load Centers, and MCCs,
  • Battery Chargers and Inverters,
  • Vital 125vdc and 120vac Distribution The analysis considered the reactor operating normally at power with no equipment failures prior to the seismic event. The EDGs are not operating, but are available. The seismic event was presumed to cause a Loss of Offsite Power (LOOP) and a normal reactor trip.

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 EOG operation, as well as Class 1E battery chargers and inverters, must function as necessary.

The following components were identified for control circuit review for SILO conditions:

  • 4kV Emergency Bus Feeder Breakers (Emergency and Offsite sources)
  • 480v Emergency Bus Feeder Breakers

SUMMARY

OF SELECTED COMPONENTS A list of the contact devices requiring a high-frequency confirmation is provided in Appendix 1.

Serial No.16-455 Docket Nos. 50-336/423 Attachment 2 MPS3 HF Sensitive Equipment Functional Confirmation Page 6 of 54 3.0 SEISMIC DEMAND ESTIMATE The high-frequency functional confirmation process for the relays subject to the potential for seismic-induced contact chatter requires the mounting point seismic demand, which requires the development of in-structure seismic demand based on the GMRS input and the in-cabinet amplification of the in-structure floor motion at the location of the electrical cabinet housing the relay.

The calculation of in-structure response typically requires the development of a foundation input response spectrum (FIRS) and dynamic analysis of the structure. MPS3 has not developed these inputs from the GMRS for plant structures. Therefore, consistent with the guidance in Reference 8, Section 4.3, the in-structure response. for buildings and floor elevations where subject relays are located was estimated as described in subsection 3.1 below.

The mounting point high-frequency seismic demand was determined consistent with the guidance in Reference 8, Sections 4.4 and 4.5, and is described in subsection 3.2 below.

3.1 ESTIMATE OF HIGH FREQUENCY IN-STRUCTURE RESPONSE Per Reference 8, Sect. 4.3, the basis for calculating high-frequency seismic demand in the horizontal direction is the horizontal control point GMRS, which was developed in response to Reference 1 and reported in the MPS Seismic Hazard and Screening Report (Reference 4). As noted in Reference 8, Section 3.3, 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.

The structures of interest for the high-frequency confirmation are the Control Building, the Emergency Generator Enclosure Building, the Auxiliary Building and the Engineered Safety Features (ESF) Building. MPS is a rock site, and the Auxiliary Building and ESF Building are founded on bedrock. The Control Building and. the Emergency Generator Enclosure Building are founded on shallow soil overburden over bedrock.

The Control Building is founded on basal till, of thickness varying between 1 foot on the east side and 15 feet on the west, overlying bedrock. Isolated zones of softened till were excavated and replaced with fill concrete or compacted structural backfill. The Emergency Generator Enclosure Building wall footings are founded on basal till varying in thickness from less than 1O feet to 30 feet overlying bedrock. Based on velocity measurements obtained during site subsurface explorations conducted for initial plant construction, a representative shear wave velocity 0fs) for the dense basal till overburden material is 2200 fps.

Serial No.16-455 Docket Nos. 50-336/423 Attachment 2 MPS3 HF Sensitive Equipment Functional Confirmation Page 7 of 54 Section 3.3 of Reference 8 describes that, for buildings on shallow soil layers at rock sites, the soil layers typically shift the frequency range of seismic input towards the lower frequency range of the response spectrum. Given the guidance from Reference 8, for purposes of high-frequency sensitive equipment evaluations in this attachment, the GMRS is likely to be richer in high-frequency content than a FIRS for a shallow layer soil-founded structure at a rock site such as the Control Building and the Emergency Generator Enclosure Building. Therefore, the control point GMRS is an appropriate review level earthquake (RLE) input for the purposes of the high-frequency confirmation .

.3.1.1 HORIZONTAL SEISMIC DEMAND The horizontal response structural amplification factor to be applied for estimating the horizontal in-structure seismic demand is provided in Reference 8, Figure 4-3 and is based upon the height of the electrical cabinet (that the relay is mounted within) above the building foundation.

For the MPS3 high-frequency confirmation, this height was taken as the difference between the lowest floor elevation and the floor elevation of the cabinet anchorage.

The horizontal seismic demand was calculated in accordance with Reference 8, Equation 4-1 a:

SAcH =SAGMRS

  • AF SH SAcH is the Spectral Acceleration, Clipped Horizontal (i.e., in-structure [floor] horizontal acceleration).

SAGMRS is the peak GMRS between 15-40Hz. The SAGMRs value is 0.422g from Reference 4.

The horizontal GMRS is plotted in Figure 3-1.

AFsH is the Horizontal Response Structural Amplification Factor from Reference 8, Figure 4-3.

3.1.2 VERTICAL SEISMIC DEMAND The vertical response structural amplification factor to be applied for estimating the vertical in-structure seismic demand is provided in Reference 8, Figure 4-4 and is based upon the height of the electrical cabinet (that the relay is mounted within) above the building foundation. For the MPS3 high-frequency confirmation, this height was taken as the difference between the lowest floor elevation and the floor elevation of the cabinet anchorage.

The vertical seismic demand was calculated in accordance with Reference 8, Equation 4-1 b:

SAcv = SAvGMRS

  • AF sv SAcv is the Spectral Acceleration, Clipped Vertical (in-structure [floor] vertical acceleration).

Serial No.16-455 Docket Nos. 50-336/423 Attachment 2 MPS3 HF Sensitive Equipment Functional Confirmation Page 8 of 54 SAvGMRs is the peak estimated Spectral Acceleration, Vertical GMRS in the 15 to 40Hz range ..

The peak SAvGMRs is the maximum product of the Vertical-to-Horizontal (V/H) function values and the corresponding horizontal GMRS values between 15 and 40Hz. The GMRS values are from Reference 4. The V/H function is derived from Reference 8, Tables 3-1 and 3-2, utilizing the GMRS peak ground acceleration (PGA) (0.190g] and the shear wave travel time from a depth of 30 meters to the ground surface (Vs30) from Reference 4. For MPS3, the V/H function values are between 0.680 @ 15 Hz and 0.860 @ 40Hz, and are based on the GMRS Horizontal PGA = 0.19g and Vs30 > 1, 000 mps corresponding to a site class 'B-Hard' per Reference 8, Table 3-2. The maximum product of the V/H function values and the corresponding GMRS is 0.31g, which occurs at 40Hz (GMRS = 0.36g, V/H = 0.86). The GMRS, estimated vertical GMRS (VGMRS), and the V/H Ratio values are plotted in Figure 3-1, along with the SSE spectrum.

AFsv is the Vertical Response Structural Amplification Factor from Reference 8, Figure 4-4.

3.2 ESTIMATE OF HIGH FREQUENCY MOUNTING POINT SEISMIC DEMAND The mounting point seismic demand was determined by applying in-cabinet amplification factors to the in-structure demand, as described in Reference 8, Sections 4.4 and 4.5.1.

The in-structure demand was determined as described in Section 3.1 above. The in-cabinet amplification factor is applied to account for the amplification of the structure seismic response at the cabinet anchor points. The in-structure demand (horizontal or vertical) was multiplied by the applicable in-cabinet amplification factor to obtain the mounting point demand.

Horizontal cabinet amplification factors used were:

Motor Control Centers AFc =3.6 Switchgear (flexible panels) AFc =7.2 Control Cabinets (e.g., Control Room electrical panels AFc =4.5 and bench boards, etc.)

Cabinet types were determined based on guidance in EPRI NP-7148, "Procedure for Evaluating Nuclear Power Plant Relay Seismic Functionality" (Reference 11).

The vertical cabinet amplification factor used was AFc =4.7 for all three cabinet types.

For electrical cabinets/enclosures that did not correspond to the listed cabinet types, in-cabinet amplification factors consistent with the cabinet configuration were used and justified on a case-by-case basis.

Serial No.16-455 Docket Nos. 50-336/423 Attachment 2 MPS3 HF Sensitive Equipment Functional Confirmation Page 9 of 54 The mounting point demand , ICRSc, used in the horizontal and vertical directions for evaluation of the relays was the product of the clipped in-structure demand and the applicable cabinet amplification factor within the 15 to 40 Hz frequency range, as described in Reference 8, Sections 4.4:

ICRScH =AFcH

Seismic demand was determined as described in Section 3.0. The deterministic high confidence of low probability of failure (HCLPF) capacity of the relay device was determined in accordance with the guidance of Reference 8, Section 4.5.

4.1 HCLPF Component Capacity The HCLPF capacities of the relays were developed based on the guidance in Reference 8, Section 4.5.2. The effective wide band capacity, TRS, is given by Reference 8, Equation 4-5:

SAT is the Spectral Acceleration, Effective Spectral Test Capacity (Relay Seismic Capacity) for relays as obtained from one of the following sources:

  • EPRI High Frequency Test Program (References 7 and 8)
  • Generic Equipment Ruggedness Spectrum (GERS) (Reference 9 and 10)
  • Seismic Qualification Reporting and Testing Standardization (SQURTS) (Reference 14)
  • Site-specific seismic qualification test data Certain relay model numbers identified on the relay list are not explicitly covered by the testing referenced in the list above and a comparison of the relay to other similar relay types having seismic qualification test data (e.g., same manufacturer & same family of relay, similar size, shape, features, construction, etc.) was made in those cases in order to provide a SAT value.

As an alternative to relay-specific seismic margin evaluations, the adequacy of relay seismic capacity (with respect to the GMRS) for selected relays not covered by EPRI High Frequency Test Program testing, GERS, or SQURTS has been evaluated through an assessment of the original site specific seismic qualification basis for electrical components. The MPS3 seismic licensing basis is IEEE-323 1974 (Reference 15) and IEEE-344 1975 (Reference 16), and safety related relays contained within plant control panels, motor control centers, switchgear, etc., were qualified to the MPS3 SSE per the requirements of IEEE-344 1975 (Reference 16).

Seismic qualification was performed to design specifications which established, based on the SSE, the applicable mounting point seismic demand for each component (panels, motor control centers, switchgear, etc.) based on applicable structure and floor acceleration response spectra.

Subsequent changes to the plant have maintained the original seismic qualification of electrical components through the MPS3 Design Control Program.

Comparing the peak spectral acceleration from the MPS3 SSE (0.459g between 2 and 6 Hz from Reference 4) to the peak spectral acceleration from the GMRS (0.422g at 15 Hz from

Serial No.16-455 Docket Nos. 50-336/423 Attachment 2 MPS3 HF Sensitive Equipment Functional Confirmation Page 11of54 Reference 4), the SSE peak exceeds the GMRS peak by approximately 9%. This exceedance would be expected to translate to a higher in-structure response and mounting point seismic demand with respect to the demand estimated for the GMRS (refer to Section 3.0), although the peak would occur at lower spectral frequencies. From the EPRI High Frequency Test Program (References 7 and 8), the capacity of relays (with respect to contact chatter) in the high-frequency range was shown to be equal to or greater than the capacity of the relay in the lower frequency range . It follows, then, that relays qualified to the MPS3 design basis SSE (to higher accelerations at lower frequencies) would be expected to function acceptably at the (lower acceleration, higher frequency) GMRS-level mounting point demand. Based on the relay-specific seismic margin evaluation performed for the majority (approximately 75%) of MPS3 relays (see Appendix 1) that concludes that there is considerable margin to contact chatter, this alternative approach to show margin to contact chatter for a portion of the relays (approximately 25%) is reasonable for MPS3.

FK is the Conservative Deterministic Failure Margin (CFDM) Knockdown Factor and its value depends on the source of the test value chosen to represent test capacity. FK was obtained from Reference 8, Table 4-2.

FMs is the Multi-axis to Single-axis Correction Factor and is equal to either 1.0 or 1.2 depending on the expected seismic response of the relay enclosure cabinet. The value of FMs was chosen consistent with the guidance from Reference 8, Section 4.5.2.

The effective wide band capacity, along with the source for the device capacity, is tabulated for each evaluated relay in Appendix 1.

4.2 SEISMIC MARGIN EVALUATION The seismic margin to the onset of contact chatter was determined by comparing the HCLPF capacity, TRS, to the mounting point seismic demand, ICRSc, to obtain the capacity/demand ratio:

CID= TRS I ICRSc (C/D is determined for horizontal and vertical directions) .

The results of the relay chatter evaluation is tabulated for each evaluated relay in Appendix 1.

Two representative sample relay evaluations are included in Appendix 2.
