1.0 BACKGROUND

AND PURPOSE

1.1 Background

Calculation No.: 0098-0189-CALC-001 Revision No.: 1 Page No.: 6 The safety-related 2400V Buses IC and ID at Palisades are equipped with two levels of undervoltage relay protection: the First Level Undervoltage Relay (FLUR) and the Second Level Undervoltage Relay (SLUR) (Reference 8.2.1 ). Upon actuation of either relay, the emergency diesel generators (EDGs) are started, the incoming breakers connecting the buses to offsite power trip, and load shedding occurs. The safety-related buses are then transferred to their respective EOG so the onsite power source can provide adequate equipment voltages. Both relays have time delays to prevent spurious trips, so that voltage must remain below the relay's dropout voltage setpoint for the duration of the delay before actuation occurs. The FLUR dropout voltage setpoint is set to a low voltage and is intended to provide protection during sudden loss of voltage. As such, the FLUR time delay is relatively short. The SLUR dropout voltage setpoint is set to a voltage higher than the FLUR dropout and is designed to actuate on voltage dips below normal motor starting voltage with the intention of protecting safety-related equipment from degraded voltage conditions. Since voltage conditions are not as low as for the FLUR, the SLUR time delay is longer. In an NRC letter to Consumers Power Company dated June 3, 1977 (Reference 8.1.2), the following requirements for Palisades' SLUR time delay were established: The time delay shall not exceed the maximum time delay that is assumed in the FSAR Accident Analyses; The time delay shall minimize the effect of short duration disturbances from reducing the availabi lity of the offsite power source; and The time delay shall not allow the degraded voltage condition to result in fai lure of safety systems or components. There are two time delays associated with the SLUR: an internal time delay and an external time delay. The total SLUR time delay, which is subject to the requirements above, is the sum of the internal and external time delays. The primary design concern with this total SLUR time delay is that when a starting or running motor is subjected to degraded voltage conditions, it is possible that the terminal voltage of that motor will be low enough for the motor to stall, thereby drawing currents near locked rotor values. Under these conditions, the motor will continue to draw this high current for up to the total SLUR time delay, which could cause the upstream protective device for that motor to trip. If the motor protective device trips, then the motor will be unavailable when loads are transferred to the EOG, which could affect redundant components. 1.2 Purpose The purpose of this calculation is to determine the maximum acceptable total time delay for the SLUR that will allow safety-related loads to perform their safety function during sustained undervoltage conditions for the safety related 2400V buses at Palisades Nuclear Plant.

SUMMARY

OF RESULTS AND CONCLUSION Calculation No.: 0098-0189-CALC-001 Revision No.: Page No.: 7 The following sections present the maximum total SLUR time delay that can be sustained by each load type, and by the most limiting individual loads. The total SLUR time delay is a sum of the internal SLUR time delay and the external SLUR time delay. Results presented in Sections 7.1, 7.3, 7.4, and 7.5, and Appendices D, F, G, and Hare in terms of the external SLUR time delay that can be sustained by each load. The external SLUR time delay is calculated by subtracting an internal SLUR time delay of0.8 seconds from the total SLUR time delay. Therefore, for the loads discussed in the Sections and Appendices listed above, the total SLUR time delay results presented in the following sections are equal to the external SLUR time delay results presented in the corresponding appendix, plus the 0.8 second internal SLUR time delay. Results are presented in tenns of the maximum SLUR time delay that can be sustained by each load; however, for motors, this includes a subsequent start on the EOG after the SLUR trips. For example, it states below that Auxiliary Feedwater Pump P8A can support a total SLUR time delay of7.0 seconds. This means that after sustaining a degraded voltage condition for 7.0 seconds, the motor will still be able to start when sequenced onto the EOG and perform its safety related function.

2. 1 2400V Safety-Related Motors All safety-related 2400V motors can perform their safety-function under a sustained degraded grid voltage condition for a total (external plus internal) SLUR time delay of at least 7.5 seconds with the following exceptions:

Containment Spray Pump P54B can support a total SLUR time delay of 5.9 seconds Auxiliary Feedwater Pump P8A can support a total SLUR time delay of 7.0 seconds Containment Spray Pump P54A can support a total SLUR time delay of7.2 seconds Raising the overcurrent relay setting of the Containment Spray Pump P54B motor breaker to match the existing setting of the Containment Spray Pump P54A motor breaker wi ll al low Containment Spray Pump P54B to support a total SLUR time delay of 7.2 seconds. Raising the overcurrent relay setting of this breaker to match P54A can be performed while still maintaining coordination with upstream protective devices and with the motor damage curve (Section 7.7. l). If the total SLUR time delay is greater than 7.0 seconds, then there is the potential the overcurrent relay of the Auxiliary Feedwater Pump P8A motor breaker will trip. Auxiliary Feedwater Pump P8A does not sequence on the Emergency Diesel Generator until 45 seconds into the transient, and the breaker relay reset time is only 9 seconds. This means the overcurrent relay will reset prior to P8A starting on the EOG. In addition, this analysis has demonstrated that this transient wil l not result in any thermal damage to the P8A motor (Section 7.7.2). 2.2 480V Safety-Related Loads All safety-related 480V loads can perform their safety-function under a sustained degraded grid voltage condition for a total (external plus internal) SLUR time delay of at least 7.4 seconds with the following exception:

Calculation No.: 0098-0189-CALC-001 Revision No.: Page No.: 8 Containment Cooler Recirculation Fans VI A and V3A can support a total SLUR time delay of 2. I seconds The overcurrent trip relays for the Containment Cooler Recirculation Fans VI A and V3A have a nominal setting of20 seconds with an allowable tolerance band of7 seconds to 35 seconds. The minimum allowable tolerance of 7 seconds results in a total SLUR time delay of2. l seconds. Raising the minimum allowable tolerance of these overcurrent relays to 15 seconds would result in a total SLUR time delay of 7.6.seconds for the Containment Cooler Recirculation Fans. A review of previous surveillance tests on these relays show a minimum tolerance of 15 seconds provides sufficient margin to previous as-found values, so raising the minimum allowable tolerance to 15 seconds could be performed administratively without changing the actual setting (Section 7.7.3). 2.3 Distribution Breakers and Fuses Class IE distribution breakers wil l allow for a total SLUR time delay up to 9.8 seconds. All Class IE fuses evaluated wil l allow for a total SLUR time delay up to 10 seconds. 3.0 METHODOLOGY The methodology in this calculation is based on the following bounding scenario: An accident occurs at the same moment that a degraded grid voltage condition occurs causing the SLUR to dropout (starting the time delay relay clock). Safety-related loads attempt to start at the degraded voltage and draw elevated current for the duration of the total SLUR time delay, challenging their protective device settings. Once the total SLUR time delay is reached, the associated 2400V bus is disconnected from its offsite power source and transfers to the EOG. The scenario conservatively assumes the EOG is at rated speed and voltage when the SLUR time delay has expired, so the transfer from offsite power to the EOG is immediate. Safety-related loads are transferred to the EOG and must complete a start at rated voltage without the protective device tripping the load offline. For the 2400V motors, the period of time during which the motor is de-energized before being sequenced on the EOG is credited because the overcurrent relay for the 2400V breakers will reset toward an un-tripped state during this time. This methodology is consistent with the NRC guidance provided in Regulatory Issue Summary (RlS) 2011 -12 (Reference 8. 1.1 ). Prior to SLUR actuation, the bus voltage can be at any voltage below the SLUR maximum dropout down to the FLUR minimum dropout. Voltages lower than the FLUR minimum dropout will result in a FLUR relay trip, which occurs over a shorter duration. The protective devices evaluated in this calculation trip on overcurrent. Therefore, the bounding scenario for each load (the scenario most likely to cause a protective device trip) will result in the largest possible current for the duration of the SLUR time delay.

mMPR Calculation No.: 0098-0189-CALC-001 Revision No.: Page No.: 1 9 The evaluations below determine the maximum time delay allowable in a worst-case bounding scenario for each load. The maximum allowable time delay for each load of concern is determined as the shortest time delay that would cause the load's protective device to trip in the bounding scenario. The bounding scenario used for each load type is briefly introduced below, and discussed in more detail in Section 7.0. 3.1 Motors In order to evaluate the bounding scenario, a limiting degraded voltage must be determined for each motor. At Palisades, the FLUR does not protect against motor stall. In other words, motor stall can occur without voltage dipping below the FLUR dropout. Induction motors are modeled as constant impedance devices at locked rotor (stalled) conditions, which is consistent with known behavior. Accordingly, motor locked rotor current increases as voltage increases. This means that for the motors in the SLUR evaluation, the maximum current does not occur at the lowest voltage (equal to the FLUR minimum dropout), but at the maximum voltage at which the motor may be stalled. This voltage is found for each motor based on the motor modeling approach used as discussed below. The majority of motors were analyzed using a simplified static motor start approach where the current draw of each motor is constant during both the SLUR time delay and the subsequent start on the EDG. This approach is easier to implement and contains more conservatism. However, in order to gain design margin for the most limiting 2400V motors, a dynamic motor start approach was implemented for these limiting 2400V motors. This approach models a more realistic, transient locked rotor current draw. These two approaches are discussed in the following sections. Induction motors that run during an event, but that are not auto-started, are evaluated the same as motors that start immediately for simplicity and conservatism. In other words, motors running prior to the event are modeled as starting at the onset of the event. 3.1.1 Static Motor Start Approach The static motor start approach treats current as a constant during both the SLUR time delay and the subsequent start on the EDG. Current is bounded by using locked-rotor Amps (LRA). Since the motors are treated as constant-impedance devices during the scenario, LRA is scaled down to the degraded voltage for the duration of the SLUR time delay, but the LRA associated with 100% of rated voltage is used during the EDG start period. All 480V motors, and nine of the 15 2400V motors are evaluated using a static motor start approach. The 2400V motors evaluated using this approach are Service Water (SW) Pumps P7A, P78, and P7C, Component Cooling (CC) Pumps P52A and P528, High Pressure Safety Injection (HPSI) Pumps P66A and P668, Low Pressure Safety Injection (LPSI) Pump P678, and Auxiliary Feedwater (AF) Pump P8C. The degraded voltage used for the analysis is taken to be the minimum voltage at which the motor is guaranteed to start. Since the motor is assumed stalled and drawing LRA for the duration of the SLUR time delay, this voltage bounds all lower voltages. Since the minimum voltage at which the motor can eventually start may not necessarily allow the motor to start

Calculation No.: 0098-0189-CALC-001 Revision No.: Page No.: 10 before the end of the SLUR time delay, a higher voltage could be more limiting if the acceleration time at the higher voltage was greater than or equal to the SLUR time delay. However, since the minimum motor start voltage for the motors is between 70 and 80 percent rated voltage and the motors allow for a total SLUR time delay greater than 7 seconds (shown in this analysis), most motors at these voltages will not take longer than the SLUR time delay to ful ly accelerate. ff a motor does take longer, it will be by a small margin, and the conservatism introduced by using LRA for the entire duration of the SLUR time delay ensures the results are still conservative. Furthermore, the motors for which a static motor start is used have margin with respect to expected acceptance criteria, so that it is not deemed necessary to perform the more detailed analysis required to determine the exact effect that voltage has on the scenario. 3.1.2 Dynamic Motor Start Approach The dynamic motor start approach uses a dynamic model to simulate two motor start transients: one where the motor attempts to start at some degraded voltage, and one where the motor starts at rated voltage on the EDG. The model uses a motor torque-speed curve and a load torque-speed curve to model the acceleration of the motor, and then uses a motor current-speed curve and the Time Characteristic Curve (TCC) of the overcurrent relay to model the tripping of the relay. This approach removes the unrealistic conservatism of assuming a constant LRA during both portions of the analysis, and allows for a more accurate limiting voltage to be identified. Six of the 15 2400V motors are evaluated using a dynamic motor start approach: Containment Spray (CS) Pumps P54A, P54B, and P54C, AF Pump P8A, LPSI Pump P67 A, and CC Pump P52C. The software tools developed in Reference 8.4.1 and stored in Reference 8.4.2 are used to implement this dynamic motor start approach. These software tools have been verified and accepted for use in accordance with MPR's 10 CFR 50 Appendix B. 3.2 Battery Chargers Battery chargers are treated as constant power devices per Assumption 4.1.7, so that current increases as voltage decreases. This makes lower voltages more limiting for the battery chargers. Using the FLUR inverse time relay, a voltage is determined at which the FLUR will trip before a bounding SLUR time delay. Evaluating the protective devices at this voltage will bound the effect of degraded voltage on the battery chargers. 3.3 Distribution Breakers For distribution circuit breakers, a bounding current for the duration of the SLUR time delay is estimated using data from all loads downstream of the breaker (including non-safety loads). Bounding current for the breaker is determined by summing the current magnitude of individual loads. Diversity factors are then applied for each bus, lowering the current to a more realistic value based on normal loading conditions. A voltage level of 80 percent rated voltage is used for al I loads in the distribution breaker evaluation during the degraded voltage condition. Since all motors are assumed to be in locked rotor conditions, the higher the voltage, the more conservative the evaluation. Since all motors can start at 80 percent voltage (Reference 8.7.2), the use of this voltage magnitude is

mMPR Calculation No.: 0098-0189-CALC-001 Revision No.: Page No.: 11 conservative for motors. Since motors draw much higher currents than static loads in the evaluation, the overall calculated current using this approach is bounding. The bounding current for each individual load is determined by one of the following methods:

1. If the load is a motor and its locked-rotor current is known, 80 percent locked rotor current (LRA) is used.
2. If the load is a motor and its locked-rotor current is not known, horsepower is used to estimate 80 percent LRA.
3. If the load is not a motor and its apparent power (kV A) is known, the load is evaluated as a motor load and the kV A value is used to estimate 80 percent LRA. The one exception is if the load is clearly labeled as a "lighting" load. In this case, the load is treated as a static load and the kVA value is used to estimate 80 percent full load current (FLA).
4. If the load is not a motor and apparent power is not known, but real power (kW) is known, then the load is evaluated as a static load and the kW value is used to estimate 80 percent FLA.

A block start of all motors at 100 percent voltage (and rise of all static loads to 100 percent full load current) is then considered for a duration of 4 seconds to conservatively bound the effect of a subsequent transfer to the EOG. The duration of 4 seconds may not bound the acceleration time of all motors, but it is deemed suitable for this purpose due to the following conservatisms in this approach: I. Not all motors would actually start on the EOG;

2. Motors would not start at the same time, but would be sequenced onto the EOG, possibly lowering cumulative current to below the pickup current of the overcurrent setting of the breaker;
3. Motors would average less than LRA over the start duration; and
4. Many motors would take less than 4 seconds to start.

After the 4 second start duration, it is assumed that all loads are at full load current, and the breaker current is far below pickup current. The protective device is then evaluated using the current magnitude at degraded voltage and rated voltage to determine the SLUR time delay length which would cause the protective device to trip. Intermittent loads such as elevators, welding outlets, and service platforms are not included in this evaluation because it is unlikely these loads would be running during the accident scenario evaluated.

~MPR 3.4 Fuses Calculation No.: 0098-0189-CALC-001 Revision No.: Page No. : 12 The fuses that protect the starters for starting MCC loads are evaluated against the inrush current of the starters to ensure the fuses do not melt during sustained degraded voltage. Each starter is assumed to be at pickup voltage. 3.5 Comparison of Results to Acceptance Criteria This calculation does not impose an acceptance criterion on the maximum SLUR time delay. Instead, this calculation determines an allowable maximum SLUR time delay to ensure safety-related loads can perform their required safety function during a worst-case sustained degraded grid voltage condition. The total SLUR time delays presented in Section 2.0 are based on the acceptance criterion that protective devices to safety-related loads must not trip during the analyzed scenario. This acceptance criterion was used to simplify the analysis approach, but tripping of a protective device does not necessarily mean the associated load will not be able to perform its required safety function. To demonstrate a load can sti 11 perform its safety function even if its upstream protective device has tripped, two additional acceptance criteria are applied: (1) the protective device must reset before the time in the scenario when the load is required to perform its safety function, and (2) the transient of tripping the protective device and subsequently restoring the load must not cause any damage to the load. Due to the different analyses performed for different components, there are three different types of results, and each must be compared against acceptance criteria in a different way. These methods are discussed in the following sections. 3.5.1 Statically Started Motors, Battery Chargers, and Distribution Breakers For battery chargers, distribution breakers, and motors evaluated using a static motor start, the maximum technical specification value for the internal SLUR time delay (0.8 seconds from Reference 8. 7.1) was subtracted from the total al lowable SLUR time delay value to get the maximum allowable SLUR external time delay. This was done to facilitate comparison of the SLUR external time delay to future proposed changes to this setting. The results presented in Section 2.0 provide the total SLUR time delay by adding the maximum allowable SLUR internal time delay of 0.8 seconds with the calculated SLUR external time delay. 3.5.2 Dynamically Started Motors For motors evaluated using a dynamic motor start, a maximum total allowable SLUR time delay is calculated directly without subtracting the internal SLUR time delay. 3.5.3 Fuses Fuses are shown to meet acceptance criteria by comparing currents rather than times. Some of the fuses are stated by vendor documentation to not melt below a certain current, regardless of the duration of which the current is applied. The other fuses are stated by vendor documentation

Calculation No.: 0098-0189-CALC-001 Revision No.: Page No.: 13 to not melt below a certain current for IO seconds, a value that is expected to always bound the total SLUR time delay. Therefore, fuses are shown to meet acceptance criteria if the expected current running through the fuses is less than the current at which the fuse wi ll melt. 4.0 ASSUMPTIONS The following assumptions are made in this calculation. Some assumptions are explicitly referenced upon use in the calculation, and others are used implicitly. 4.1 Assumptions with a Basis Motors 4.1.1 DELETED.

4.1.2 Assumption

The motors for Engineering Safeguards Room Coolers V27 A and V27D have the same acceleration time as Engineering Safeguards Room Coolers V27B and V27C. Basis: References 8.5.30, 8.5.31, 8.5.46, and 8.5.48 provide the same horsepower, full load current, kV A code, and other parameters for the four motors, providing basis for this assumption.

4.1.3 Assumption

A I second acceleration time is bounding for motor-operated valves (MOY). Basis: EPRl In-Situ testing report MPR-l 512 (Reference 8.1.3) provides motor current traces for many MOVs during the static and dynamic tests. A review of this document reveals that all MOVs tested had acceleration times less than I second (most being in the 0.2 to 0.4 second range). Additionally, Reference 8.1.4 uses a 0.1 second start time in a calculation applicable to all Reliance 3-phase MOY motors. These references are judged to provide suitable basis for this assumption.

4.1.4 Assumption

A I second acceleration time for motor-operated dampers (MOD) is suitable for the purposes of this calculation. Basis: The "acceleration time" of dampers as used in this analysis is equivalent to the "inrush" duration, or period of elevated current. An inrush duration of I second is a typical, bounding value used for analyses of motors connected to valve operators. Actual measured inrush times for valve motors is more commonly on the order of0.1 seconds, and therefore the use of I second is reasonably bounding. Furthermore, the results of the evaluation for the dampers shown in Table 13 show plenty of margin with respect to the limiting values presented in Section 2.2.

4.1.5 Assumption

A 5 second acceleration time is bounding for Diesel Generator Room Vent Fans V24A, V24B, V24C and V24D. Basis: The 3rd Design Input Record to EC66090 (Reference 8.10.3) documents a crude

mMPR Calculation No.: 0098-0189-CALC-001 Revision No.: Page No.: 14 test in which two starts of Diesel Generator Fan Y-24B were measured. The acceleration times were measured as 1.7 seconds and 1.4 seconds. The DIR states that the inaccuracy of the method is small enough to use a 3 second start time for the motor. This provides adequate assurance that 5 seconds is a bounding start time. Per the DIR, the start time for fan Y-24B is also representative of fans Y-24A, Y-24C, and Y-24D.

4.1.6 Assumption

The locked-rotor current for damper D-21 is assumed to be the same as damper D-20. Basis: References 8.6.1 and 8.6.2 give the KY A and full load rating for both motors, locked-rotor current for damper D-20, but no locked-rotor current for damper D-21. The dampers have the same KYA ratings, but damper D-20 has a slightly higher full load current than damper D-21. Therefore, it is reasonable to assume the locked-rotor current for damper D-21 is no greater than the locked-rotor current for damper D-20. Battery Chargers 4.1. 7 Assumption: Battery chargers act as constant power devices as the magnitude of the AC input voltage varies. Basis: A battery charger by design maintains a constant DC output voltage (i.e., the battery float voltage) over a range of input AC voltages. Battery charger output current under these conditions is determined by the DC loading and the float current requirements of the battery. DC loading and battery current are independent of AC voltage magnitude. Accordingly, since output voltage is constant and output current is independent, the battery charger will behave as a constant power load. If the AC voltage dips below the minimum value required by the battery charger to function, then the battery charger may discontinue operating, at which point the batteries will be relied upon to provide power to the DC loads. Given the above, this assumption is conservative and requires no further evaluation. Protective Devices

4.1.8 Assumption

The time required to trip an overcurrent device at a lower current bounds the time required to trip at a higher current. Basis: The time required for overcurrent trip devices to trip either remains constant as current increases, or decreases as current increases. Accordingly, this assumption is conservative and requires no further evaluation.

4.1.9 Assumption

The time required to damage a motor at a lower current bounds the time required to damage at a higher current. Basis: The time required to thermally damage a motor at high currents decreases as current increases, because higher currents mean more heat is generated. Accordingly, this assumption is conservative and requires no further evaluation.

~MPR Calculation No.: 0098-0189-CALC-001 Revision No.: Page No.: 15 4.1.10 Assumption: Each thermal overload heater in the G30T family of heaters follows the same time overcurrent (TOC) curve with current normalized by each heater's ultimate operating current (which increases with larger heaters). Data from different heater sizes are used to generate a best-fit curve (of the form y=Ax") representing the normalized TOC curve for the family of heaters, which may be used to determine trip time for heater sizes at currents for which trip time is unknown. Basis: The close fit to known data points (as evidenced by the high R2 value) of the best-fit curve shown in Figure 3 provides basis for this assumption. 4.1.11 Assumption: Each thermal overload heater in the CR123C family of heaters follows the same time overcurrent (TOC) curve with current normalized by each heater's ultimate operating current (which increases with larger heaters). Data from different heater sizes are used to generate a best-fit curve (of the form y=Ax") representing the normalized TOC curve for the family of heaters, which may be used to determine trip time for heater sizes at currents for which trip time is unknown. Basis: The close fit to known data points (as evidenced by the high R2 value) of the best-fit curve shown in Figure 4 provides basis for this assumption. 4.1.12 Assumption: Minimum full load motor current for ITE thermal overload heater G30T7 protecting Air Filter Unit Fan Modulating Dampers D-20 and D-21 is 0.321 A (from Reference 8. I 1.5), so that the operating current of the heater is 1.25*0.321 A= 0.401 A. Basis: References 8.6.1 and 8.6.2 give the category number of the G30T7 overload heater used for the loads as A20. Both Table 6 and Table 7 of Reference 8. 11.5 are applicable to A20 heaters. The tables also give different full load motor current values for the same heater based on the number of heaters used. This information is not known, so the most conservative (smallest) current is taken. This current is 0.321 A and is taken from Table 6 of Reference 8.11.5 using 3 heaters. Multiplying minimum full load current by 1.25 to obtain heater operating current is consistent with the methodology used in References 8.5.88, 8.5.89, and similar breaker setting calculations. 4.1.13 Assumption: Minimum full load motor current for !TE thermal overload heater G30T49A protecting Air Handling Unit Fans V95 and V96 is 27.2A (from Reference 8.11.5), so that the operate current of the heater is I.25*27.2A = 34A. Basis: References 8.5.91 and 8.5.97 give the category number of the G30T49A overload heater used for the loads as A20, and the NEMA size of the starter as 2. Both Table 6 and Table 7 of Reference 8.11.5 are applicable to A20 heaters. The tables also give different full load motor current values for the same heater and starter size based on the number of heaters used. This information is not known, so the most conservative (smallest) current is taken. This current is 27.2A and is taken from Table 6 of Reference 8.11.5 using 3 heaters. Multiplying minimum full load current by 1.25 to obtain heater operate current is consistent with the methodology used in References 8.5.88, 8.5.89, and similar breaker setting calculations.

mMPR Calculation No.: 0098-0189-CALC-001 Revision No.: Page No.: 16 4.1.14 Assumption: For a GE IAC66K overcurrent relay device with multiple time dial settings (set at a constant pickup current setting), all time overcurrent curves are proportional, so that the following is true: where f is a base time overcurrent curve with trip time as a function of current, X is a simple scalar modifier proportional to the time dial setting of the device, and g is the effective time overcurrent curve at a particular time dial setting. Basis: This assumption is confirmed by examining the curves on pg. 1 l of Reference 8.11.4. Distribution Breaker Evaluation The following assumption applies only to the distribution breaker evaluation and has no effect on the evaluation of the protective devices for each individual safety load. 4.1.15 Assumption: "Mixed loads", or loads for which power values are given in units of kV A, are completely made up of motor loads. Basis: Since the current though a motor load will increase in degraded voltage conditions and the current through a static load will decrease, this is a conservative assumption. Exception: If power for a load is given in units of kV A, but the load is clearly indicated as a "lighting" load, the entire load is considered static. Lighting is a resistive load, which is constant impedance. 4.2 Assumptions without a Basis There are no assumptions without a basis in this calculation. 4.3 Limitations Limitations 4.3.1-4.3.3 apply only to the evaluation of protective devices for individual loads, and are not necessarily true for the evaluation of the distribution circuit breakers. 4.3.1 This evaluation is limited to loads that are credited for mitigating a Design Basis Accident (OBA) and will only consider Class lE loads at the 2400V and 480V voltage classes. 4.3.2 Only loads directly fed from the following Class IE buses and motor control centers (MCCs) are considered in this calculation: 2400V Buses No. IC and ID 480V Buses No. 11, 12 480V MCCs 1, 2, 21, 22, 23, 24, 25 and 26

mMPR Calculation No.: 0098-0189-CALC-001 Revision No.: Page No.: 17 It should be noted that although Bus 11 is considered in this calculation, none of the individual loads satisfy the criteria for inclusion in the evaluation, either due to not being safety related (Limitation 4.3.1 ), or to not being a type of load that merits inclusion (Limitation 4.3.3). 4.3.3 For the individual component protective device checks (i.e. not the distribution breaker checks), only loads that draw more current as voltage decreases are evaluated in this calculation. The evaluated loads consist of the following types: Induction motors (including for motor operated valves and dampers) Station battery chargers 4.3.4 In the evaluation of the distribution breakers, only breakers downstream of the 2400V buses are considered, as the tripping of any breakers further upstream would only serve to disconnect the 2400V buses from offsite power, resulting in a diesel start. In addition to the buses and MCCs listed in Limitation 4.3.2, breakers to and from 480V Buses No. 19 and 20 are included. These buses do not directly carry any loads of concern, but they do supply power to MCCs I, 2, 25 and 26. These limitations result in inclusion of the 12 distribution breakers listed in Table 15. 5.0 DESIGN INPUTS The 2nd Design Input Record (DIR) to Palisades EC66090 (Reference 8. 10.2) states that all documents (Palisades documents, vendor documents, etc.) used to obtain design inputs for Revision O of this document are suitable for the purposes of this calculation, as long as they concur with the marked-up references provided in the attachment to the DIR. The references for the calculation do concur with the marked-up attachment to the DIR (with the exception of a few documents being omitted as they are not used in the calculation). The 4th Design Input Record to Palisades EC66090 (Reference 8.10.4) states that the additional documents used to obtain design inputs for Revision 1 of this document are suitable for the purposes of this calculation. The DIR lists each document covered by the DIR. Documents controlled by MPR are not included in the DIR; MPR has determined these documents are suitable for the purposes of this calculation. 5.1 SLUR Internal Time Delay The Technical Specification maximum Allowable Value for the internal SLUR time delay is 0.8 seconds (Reference 8.7. 1). 5.2 One-Line Drawings The electrical one-line drawings listed in Reference 8.8 are used to determine: I. The loads on each bus and MCC considered in the evaluation (as specified by Limitation 4.3.2).

2. All buses and loads downstream of each distribution breaker considered in the evaluation (included loads and buses not individually considered in the calculation).

5.3 Safety Loads Table 4 in Appendix A, which is provided as an Excel spreadsheet in an attachment to Design Input Record to Palisades EC66090 (Reference 8.10.1 ), shows a list of loads initially considered in the analysis. Only loads indicated as safety-related (SR) are individually evaluated in this calculation, per Limitation 4.3.1. 5.4 Motors that Drive Pumps, Fans and Valves 5.4.1 Starting Motors Table 7.5.2-2 in Reference 8.3.2 provides a list of motors that receive a Safety Injection System (SIS) actuation signal in the event of an accident. These loads are noted in this calculation as being of particular interest (as they may need to complete a full acceleration at any time). However, as noted in Section 3.1, non-starting motors are treated in this calculation as if they receive a start signal immediately, for simplicity and conservatism. 5.4.2 EDG Load Sequencing Tables 5-1 and 5-2 in Reference 8.3.3 provide the times at which motors that receive an actuation signal start after transferring to the EOG. 480V MCC motors start immediately (t=O) upon transferring to the EOG. However, 2400V and 480V bus motors experience a time delay between being disconnected from offsite power and starting on the EOG, during which each motor is de-energized. This time delay is factored into this calculation for the 2400V bus motors, but is not credited for the 480V bus motors. 5.4.3 Starting Voltage The minimum voltage at which each evaluated motor is guaranteed to start is used in this calculation as the maximum voltage at which the motor may be stalled for motors that are statically started as discussed in Section 3.1.1. Specification 5935-E-l O (Reference 8.7.2) Section 2.3 states that motors rated at 200 horsepower and higher shall be capable of starting with 70 percent rated voltage at the motor terminals, and motors rated at 150 horsepower and lower shall be capable of starting with 80 percent rated voltage at the motor terminals, unless stated otherwise. All 2400V motors evaluated in this calculation are rated at a horsepower greater than 200, so 70 percent rated voltage is used as the maximum voltage at which the motors can be stalled. The breaker setting calculation (Reference 8.5) and, as necessary, coordination curve (Reference 8.9) for each 2400V motor confirms this value. All 480V non-MOY motors evaluated in this calculation are rated at a horsepower less than 150, so 80 percent rated voltage is used as the maximum voltage at which the motors can be stalled. No other document used as a design input in this calculation contradicts this value for any of the 480V motors evaluated.

Calculation No.: 0098-0189-CALC-OO 1 mMPR Revision No.: Page No.: 19 For MOVs, Appendix G ofEA-ELEC-VOLT-051 (Reference 8.3.6) lists the voltage required to start each MOY as 70 percent rated voltage, so this is the maximum voltage at which the MOVs can be stalled. Motors that are dynamically started as discussed in Section 3.1.2 do n0t require starting voltage as an input. These motors are evaluated across a range of voltages, so the effect of voltage is fully taken into account for these motors. 5.4.4 Locked Rotor Current The Jocked rotor current in Amps of each motor is used to determine the current draw of the motor at stalled and starting conditions for motors that are evaluated using a static motor start as discussed in Section 3.1.1. LRA is found in the breaker setting calculation (Reference 8.5) of each motor evaluated in this calculation. 5.4.5 Acceleration Time As discussed in Section 3.1 of this calculation, the scenario to be considered includes a motor start for each of the motors evaluated. This requires knowledge of how long it takes each motor to accelerate to running speed from a de-energized or stalled condition for motors that are evaluated using a static motor start as discussed in Section 3.1.1. Dynamically started motors using the approach discussed in Section 3.1.2 do not require acceleration time as an input. The following is a list of sources for the acceleration time of each non-MOY or MOD motor, in order of preference. The specific source for each acceleration time is indicated in the evaluation tables in Appendices D and F.

1. Breaker setting calculation (Reference 8.5) for the motor.
2. Assumed to be equal to the acceleration time of a motor of the same type per Assumption 4.1.2.
3. Appendices D and J of EA-ELEC-VOLT-OJA (Reference 8.3.3) for motors downstream of Bus IC and 1 D, respectively (these tables only include starting motors).
4. Assumed to be 5 seconds per Assumption 4.1.5.

An acceleration time of I second shall be used for all MO Vs in this calculation per Assumption 4.1.3. 5.4.6 Motor Curves and Inertia For motors that are dynamically modeled as discussed in Section 3.1.2, a torque-speed curve and a current-speed curve are required for the motor. Additionally, the total inertia of the rotating assembly (including motor, load, and coupling) is required. EA-ELEC-VOLT-040 (Reference 8.3.4) provides this information.

mMPR 5.4. 7 Load Curves Calculation No.: 0098-0189-CALC-001 Revision No.: Page No.: 20 For motors that are dynamically modeled as discussed in Section 3.1.2, a torque-speed curve is required for the load. The loads attached to all dynamically modeled motors are pumps. Calculation CALC-0098-0186 Rev. I (Reference 8.4.4) provides these curves. The curves provided load the motor to l 00 percent of its nameplate brake horsepower. 5.4.8 Loading Condition For motors that are dynamically modeled as discussed in Section 3. 1.2, the power required to drive the load in the condition analyzed is needed in order to appropriately scale the load torque-speed curve. EA-ELEC-LDT AB-005 Rev. IO (Reference 8.3.8) Tables A. I and C. l provide this information for AF pump P8A, LPSI pump P67 A, and CC pump P52C. EA-CA024154-01 Rev. I (Reference 8.3.7) provides flow information for CS pumps P54A, P54B, and P54C, and Attachments 0, P, and Q of EA-ELEC-LDT AB-005 provide the pump data necessary to calculate brake-horsepower from flow. 5.5 Battery Chargers For the battery chargers, the vendor manual (Reference 8.11.7) provides the information necessary for the evaluation. The FLUR setting calculation (Reference 8.11.6) is also used to determine an appropriate voltage level at which to perform the evaluation. 5.6 Motor Operated Dampers (M0Ds) 5.6.1 Starting Voltage Motor operated dampers have a rated power of less than l SOHP, so the starting voltage used is 80 percent of rated voltage, per Reference 8.7.2. 5.6.2 Locked Rotor Current LRA is found in breaker setting calculations (Reference 8.5) for two of the four motor operated dampers (D-7 and D-14). For the other two dampers (D-20 and D-21 ), LRA is found in Appendix N ofEA-ELEC-EDSA-001 (Reference 8.3.1). 5.6.3 Acceleration Time Since no acceleration times are given in the available input documents, the acceleration time used for motor operated dampers is I second, per Assumption 4.1.4.

5. 7 Trip Time For each current draw of each load in the evaluation, a trip time must be determined for the protective device (or the damage time of the motor, in some cases). For motors, trip time must be determined at rated locked rotor current (LRA) and reduced locked rotor current, or stall current (SA). Trip times at various currents are obtained from one of the sources below, in order of preference. Each source may only apply to one of the above currents, as indicated.

mMPR Calculation No. : 0098-0189-CALC-001 Revision No.: Page No. : 21

1. Coordination curves in breaker setting calculations (LRA, SA).
2. Stand-alone coordination curve drawings (LRA, SA).
3. Statement of trip time at specified current in breaker setting calculations (LRA).
4. Best-fit curve for family of protective devices using known trip time data. These curve fits are shown in Appendix B (LRA, SA).
5. Statement of motor damage time in breaker setting calculations. This method is used only when the protective device is specified to function only as an alarm, if the alarm trip time is too conservative (LRA).
6. Extrapolation of motor damage time data. This method is used to calculate motor damage time at stall current when the protective device is specified to function only as an alann. Extrapolation is done using damage time at higher currents, so that extrapolated times at lower current bound the damage curve. Appendix C presents the details of this method (SA).
7. If trip/damage time at reduced locked rotor current cannot be obtained from the methods above, or if sufficient margin exists, trip/damage time at reduced locked rotor current may be conservatively assumed equal to the trip/damage time at rated locked rotor current via Assumptions 4.1.8 and 4.1.9.

Trip times for the battery chargers and distribution breakers are obtained from coordination curves in breaker setting calculations (Reference 8.5), or stand-alone drawings (Reference 8.9). The specific trip time sources for each load are indicated in the evaluation tables in Appendices D through H. 5.8 Distribution Breaker Evaluation 5.8.1 Loads Although non-safety motor loads and static/heating loads are not considered individually in this calculation, they must be considered along with the individually evaluated loads in the cumulative evaluation of the distribution circuit breakers. It should also be noted that the inclusion of non-safety loads requires that the previously unconsidered MCCs 7 and 8 be evaluated. Below are the design inputs used for the loads in this evaluation:

1. [f the load is individually evaluated, the LRA or degraded voltage current value used in the individual evaluation is used in the distribution breaker evaluation.
2. If the load is a motor, and a breaker setting calculation (Reference 8.5) containing LRA is available, this LRA is used.
3. Appendix N of EA-ELEC-EDSA-001 (Reference 8.3.1) is used to obtain either LRA or power for the remaining loads.

The loads used in the distribution breaker evaluation are listed in Table 16 in Appendix H.

mMPR 5.8.2 Diversity Factors Calculation No.: 0098-0189-CALC-001 Revision No.: Page No.: 22 The loading on each bus is scaled down by a diversity factor. The diversity factors used are found in Appendix R of EA-ELEC-EDSA-001 (Reference 8.3.1 ), and are listed in Table I. Notes: Table 1. Diversity Factors for 480V Buses and MCCs Bus/MCC Diversity Factor (Note 1, 2) Bus 11 0.38 (Note 3) Bus 12 0.41 (Note 3) MCC 1 0.25 MCC 2 0.20 MCC 7 0.40 MCC 8 0.45 MCC 21 0.40 MCC22 0.45 MCC23 0.40 MCC 24 0.45 MCC25 0.25 MCC 26 0.20 I. All diversity factors are obtained from Appendix R of EA-ELEC-EDSA-001. I. All diversity factors are rounded up conservatively.

2.

These diversity factors apply only to loads fed directly from the bus. They do not apply to downstream MCCs. The downstream MCCs have their own individual diversity factors. 5.9 Starters and Fuses For the fuse evaluation, starter and fuse model information is taken from Appendix A of EA-ELEC-VOL T-050 (Reference 8.3.5). Starter data are taken from Appendix Hof EA-ELEC-VOL T-050. Fuse information is taken from Bussmann fuse catalogs (References 8.11.8 and 8.11.9). A cross reference guide (Reference 8.11.10) states that Reliance ECN and ECN-R fuses are equivalent to Bussmann FRN-R fuses, and they are evaluated as such using Reference 8.11.8. 6.0 COMPUTER CODES The analysis in Section 7.2 is performed with software tools documented and verified in Reference 8.4.1 and stored in Reference 8.4.2. The software tools include a dynamic block-

Calculation No.: 0098-0189-CALC-001 Revision No.: Page No.: 23 diagram model in the software Simulink that models a motor start, and a MATLAB function that interfaces with the Simulink model to execute the analyses. The analyses were performed on MPR computer number 3729 running Windows 7, 64-bit operating system. Table 2 identifies the interpreted fi les used in this analysis as required by the MPR Nuclear Quality Assurance Manual (Reference 8.4.5). No installation verification is required for the software tools, as the verification calculation was performed on the same computer used for this analysis. Seven cases were run as part of this calculation: one case for each dynamically modeled motor discussed in Section 3. 1.2, and one extra case for CS pump P548 with a modified relay setting. The files used in this analysis are stored in Reference 8.4.3 and listed in Table 3. Table 2.

This includes SW Pumps P7 A, P7B, and P7C, CC

mMPR Calculation No.: 0098-0189-CALC-001 Revision No.: Page No.: 24 Pumps P52A and P52B, High Pressure Safety Injection (HPSl) Pumps P66A and P66B, Low Pressure Safety Injection (LPSl) Pump P67B, and Auxiliary Feedwater (AF) Pump P8C. Loads powered directly by the 2400V buses are discussed separately from 480V loads because the former experience a time delay before being energized by the EOG after the actuation of the SLUR This time delay impacts the evaluation, as discussed in the following sections. All 2400V loads are induction motors that are protected by GE IAC66K time overcurrent relays. The GE IAC66K relay uses an induction disk (Reference 8.11.4) to provide its time overcurrent function. 7.1.1 Scenario The bounding scenario used to evaluate the acceptability of the SLUR time delay for induction motors on the 2400V buses is shown in Figure I, and consists of the following steps:

a. Prior to degraded voltage conditions, the motor runs at rated voltage (below the pickup current of the protective device) or is de-energized for a long time, and all buses are connected to offsite power.
b. A sudden reduction in bus voltage causes the motor to stall (and triggers the beginning of the SLUR time delay). For conservatism, the bus voltage is taken to be the maximum voltage at which the motor may be stalled, or the minimum voltage at which the motor is guaranteed to start (typically between 70 and 80 percent of rated voltage). The current draw in this stalled condition is the locked rotor current at the stalled voltage, which is equal to rated locked rotor current scaled down by the same factor as voltage. The bus voltage stays at this level the entire duration of the internal and external SLUR time delays.
c. After this duration, the SLUR is actuated and the safety buses are transferred to the EOG. Motors are loaded onto the EOG in a sequence, so that each motor will be de-energized (and draw zero current) for some period of time following the actuation. This EOG time delay is different for each motor.
d. Upon being sequenced onto the EOG (which maintains bus voltages at rated conditions), the motor begins to start. During the motor acceleration time (the time it takes the motor to accelerate to rated speed from rest), the motor draws rated locked rotor current.
e.

Upon reaching operating speed, the motor draws normal running current indefinitely.

Current Profile Used to Evaluate SLUR Time Delay for 2400V Induction Motors 7.1.2 Calculations Time The following calculations are performed for each individual motor to determine the maximum SLUR external time delay that can be tolerated without tripping the protective device at any point in the scenario described above. Stall Current The current drawn while the motor is stalled is calculated from the following equation: where l srall is the stalled current in Amps, V% is the minimum guaranteed start voltage (and therefore maximum possible stall voltage) as a percentage of rated voltage, and Im is locked rotor current at rated voltage in Amps. Protective Device Trip Times The times at which the protective device trips at lsrall and hR are determined to be t1rip_s1a11and t1rip_s1ar1 respectively, using the sources discussed in Section 5.7. The 2400V loads are all induction motors, and each motor is protected by a GE IAC66K time overcurrent relay. The GE IAC66K protective device curves provided in the breaker setting calculations only indicate the nominal trip times. While this is adequate to demonstrate proper protective device coordination (given the large coordination margin), this is inadequate for the purpose of this calculation. Accordingly, this calculation supplements the nominal times

Calculation No.: 0098-0189-CALC-OO 1 Revision No.: Page No.: 26 obtained from the breaker setting calculations with the lower calibration limit specified in the breaker setting calculations. Specifically, first the nominal trip time is obtained from the GE IAC66K time overcurrent curve provided in the breaker setting calculation. Next the ratio of the minimum allowable calibration trip time to the nominal calibration trip time is used to scale this nominal value to obtain the minimum possible trip time. This modification is as follows:

  • teal min ttrip_min = t
  • ttrip_nom cal_nom where t1,ip_mi11 is the minimum trip time allowed by calibration at a current of interest (used as t1,ip_su,11or t1,ip_s1,ir1 in the rest of the evaluation), t1,ip_11om is the nominal trip time at a current of interest (taken from the curve), tcat_111i11 is the minimum acceptance criteria used to calibrate the device at some test current, and tcat_nom is the nominal value used to calibrate the device at the test current. The use of the ratio of minimum to nominal calibration times as a modifier stems from Assumption 4.1.14, which states that trip curves from the same class of overcurrent relay at the same pickup setting are all proportional.

Relay Reset Time While each load sits on a dead bus waiting to transfer to the diesel, its overcurrent relay starts to reset, meaning the induction disk inside the relay rotates back toward its starting position at the beginning of the transient (away from tripping). In order to quantify how far the disk resets during the EOG time delay, the total reset time at zero current (i.e. the time it takes the disk to rotate from the completely tripped position back to the completely reset position) for each relay (and setting) used is estimated as discussed in this section. Page 6 of Reference 8.11.4 states "the time required for [the GE IAC66K overcurrent relay] to reset from contact closure to the Number IO time dial position is approximately 60 seconds." Each time dial position represents some angular displacement the disk must travel in order to trip, or reset, so at a constant speed, the time the device takes to reset at the Number I time dial position is a tenth of the time the device takes to reset at the Number IO times dial position. Accordingly, reset time is calculated as 6 seconds times the nominal time dial position of the device. Critical EOG Time Delay In the evaluation scenario, the most limiting point in time can be either of the following: The end of the SLUR time delay when the motor is de-energized upon being disconnected from off-site power; or The end of the acceleration time when motor current reduces to running current. The limiting point must be known for each motor before a maximum tolerable SLUR time delay may be calculated. This is determined by considering the following scenario: the motor is stalled for just long enough to trip the overcurrent relay (the relay does not trip, but is on the very edge of tripping), is de-energized for some amount of time (which will be referenced as the "critical

mMPR Calculation No. : 0098-0189-CALC-001 Revision No.: Page No.: 27 EOG time delay", or lEDG_c,it), then performs a start, which brings the relay to the edge of tripping again. After being stalled, the induction disk of the overcurrent relay has rotated the entire angle necessary to cause a trip, so that in order to just succeed in starting the motor, the angle displaced by the disk (in the reset direction) during de-energization must be equal to the angle displaced by the disk (in the trip direction) during the motor start. Because exact angles are not known, angular displacement is expressed as a percentage of the entire trip (or reset) displacement. At a constant speed, the ratio of angular displacement may be expressed as a ratio of times as shown below: (}partial etotal W

  • tpartial tpartial

= W

  • ttotal ttotal where O is an angular displacement, w is a constant angular velocity, and t is a time during which the disk travels at the constant angular velocity. It should be noted that w is dependent on the direction the disk is travelling and the current running through the relay, so that the ratio is only valid if lpa,tial and l101a1 represent the same circumstances.

As stated above, the reset and trip displacements are equal in this scenario, so that as shown above, the time ratios are equal as well. For the reset direction, the ratio is equal to the critical EOG time delay (lEDG_c,it) divided by the total reset time (treset). For the trip direction, the ratio is equal to the motor acceleration time (lace) divided by the time is takes the device to completely trip during starting conditions (t1,ip_s1a,1). This yields the following equation: tEDG_crit tacc treset ttrip_start The critical EOG time delay that satisfies this scenario is calculated below: tacc tEDG crit =

  • treset ttrip_start For any EOG time delay (lEDG) greater than lEDc_c,it, the induction disk resets enough during de-energization to allow for a motor start even in the worst case stalling scenario, meaning that if the relay does not trip by the end of the SLUR time delay, it will not trip on the motor start, and the motor stall is the limiting point of the evaluation.

For any EOG time delay less than or equal to lEDG_crit, the induction disk does not reset enough during de-energization to allow for a motor start in the worst case stalling scenario, meaning that the limiting point of the evaluation is the motor start. Allowable SLUR Time Delay for Stall-Limited Motors For stall-limited motors, the protective device simply must be able to tolerate the stall current for the internal and external SLUR time delays before tripping, as it is known the device will not trip afterwards. The maximum allowable SLUR external time delay for the motor (tm,L~_ex1) is calculated as follows:

Allowable SLUR Time Delay for Start-Limited Motors For start-limited motors, the entire evaluation scenario must be considered. The following equation is used to calculate tmax_ew for the motor: tmax_ext = tstall_max - tint where lstall_11uff is the maximum time the motor can stay at the stall current without the motor tripping during its start. ts1all_111ax is calculated as below: tstall_max = (1 - Xnet)

In other words, X 11e1 is the trip margin that must be left in the relay at the end of the SLUR time delay. X11e1 is defined as follows: Xnet = Xstart - Xreset where Xstart is the ratio of the displacement of the induction disk (in the trip direction) during the motor start to the overall trip displacement, and Xreset is the ratio of the displacement of the induction disk (in the reset direction) during the EOG time delay to the overall reset displacement (which is the same as the trip displacement).

This includes Containment Spray (CS) Pumps P54A, P54B, and P54C, AF Pump P8A, LPSI Pump P67A, and CC Pump P52C.

7.2.1 Scenario Calculation No.: 0098-0189-CALC-001 Revision No.: Page No.: 1 29 The scenario evaluated for dynamic motor starts is similar to that evaluated for static motor starts. However, dynamic motor starts model realistic motor behavior, whereas static motor starts represent a simplified motor behavior. The following refined scenario is evaluated for dynamic motor starts:

1. A degraded voltage occurs on the grid at the same moment in time the motor receives a signal to start in response to an accident. The motor accelerates and attempts to reach rated speed, drawing elevated current. If voltage is high enough, the motor reaches rated speed and the elevated current drops to rated running current. If voltage is too low, the motor is either accelerating for the entire duration of the SLUR time delay, or the motor stalls at some speed significantly below rated, where it will continue to draw elevated current. The elevated current draw will cause the protective overcurrent relay for the motor to rotate toward a tripped position.
2. After the SLUR time delay, the SLUR actuates and trips the motor oftline. The motor is de-energized for some period of time before starting on the EOG. The protective relay for the motor resets some percentage during this time. This is calculated as the ratio of the time during which the motor is de-energized to the time it takes the relay to completely reset when the motor is drawing no current (see Section 7.1.2).
3. The motor switches to the EOG and starts at 100 percent rated voltage. The motor accelerates, drawing elevated current, until it reaches rated speed and current drops to rated running current. The elevated current draw will cause the protective overcurrent relay for the motor to rotate toward a tripped position.

7.2.2 Calculations Pump Loading In order for the software discussed in the following section to properly calculate results, the pump load exerted on the motor must be correctly represented. This is done with a load torque-speed curve. Torque-speed curves for each pump load are provided in Reference 8.4.4; however, these curves correspond to a pump brake horsepower that is I 00 percent of the motor rated horsepower. The curve must be scaled in order to represent the specific loading for the scenario, which may not be equal to I 00 percent of the motor's rated horsepower. Power is equal to torque multiplied by rotational velocity, so that at each speed on the JOO percent brake horsepower load torque curve, torque may be scaled up or down by power. This is illustrated in the following equations: P1 T1

  • w T1 P2 = T2
  • w = T2 Px%

Tx% = T100% * -p-- 100%

Table 8 in Appendix E shows the results of these calculations. CS Pumps P54A, P548 and P54C In order to determine brake horsepower, the flow through the pump must first be known. Palisades calculation EA-CA024 I 54-0 I (Reference 8.3. 7) calculates flow rates in the containment spray system during injection mode for a variety of cases. The calculation presents both minimum flow and nominal flow cases. Nominal flow cases are more conservative for this analysis, as higher flow leads to higher brake horsepower for the pump. The calculation presents both Nominal Fill-Up (NFU) cases, in which the containment spray header is initially filled with air, and Nominal Full-Flow (NFF) cases, in which the containment spray header is already filled with water. The NFU cases are more conservative because the voided header results in less resistance than the filled header, resulting in more flow. Several NFU cases are run, with different combinations of active CS pumps. Case NFU 01 assumes that P548 and P54C are both inoperable due to a common cause failure (as they belong to the same train of equipment), leaving P54A as the only active CS pump. This results in more flow through P54A than if the other pumps were operable. The case uses a containment pressure of 45psig, which is appropriate for the first few seconds of an accident scenario. Case NFU O 1 is used to obtain the flow for P54A. Case NFU 06 assumes that P54A is inoperable due to a failure, leaving P548 and P54C as the only active CS pumps. This results in more flow though P548 and P54C than if P54A were also active. P548 and P54C are on a different equipment train than P54A, so there is no single failure that could cause P54B or P54C to be operating alone. The case uses a containment pressure of 45 psig, which is appropriate for the first few seconds of an accident scenario. Case NFU 06 is used to obtain the flows for P548 and P54C. Flows are given as mass flow rates; however, volumetric flow rates are needed in order to determine pump head and pump efficiency. Reference 8.3.7 states in Assumption 4.2.8 that water is at 87°F for nominal flow cases. Input 3.35 of Reference 8.3.7 states the model uses a density of 62.14 7 lbm/ft3 at this temperature. This density is used to convert from mass flow rate to volumetric flow rate. Once flows are known for each of the three pumps, pump information in Attachments 0, P, and Q of EA-ELEC-LDT AB-005 Rev. 10 (Reference 8.3.8) may be used to determine the brake horsepower of P54A, P54B, and P54C, respectively. Each attachment contains a table that gives pump head and pump efficiency at various flows in GPM. Linear interpolation is used to find the head and pump efficiency corresponding to the determined flow. Brake horsepower is defined qualitatively as: Mass Flow* Head BHP =------ Pump Efficiency

Calculation No.: 0098-0189-CALC-001 ~MPR Revision No.: Page No.: 31 With flow in given in lbm/hr (Q), head in feet (Jl), and pump efficiency as a ratio (Ejj), brake horsepower is calculated as shown below: lbm 1 hr 1 hp Q hr

  • 1,980,000 It should be noted that the pump data presented in Reference 8.3.8 includes a column for brake horsepower; however, it is more accurate to calculate the value than to interpolate.

Reference 8.3.8 applies a margin for error to the calculated brake horsepower values. This calculation does not apply such conservatism. The following conservatisms and bounding assumptions already present in this analysis provide assurance that the analysis will yield conservative results without introducing more conservatism: The minimum calibration tolerance is used for the Time Characteristic Curve of the motor breaker overcurrent relay. The flow calculation (Reference 8.3.7) has multiple conservatisms applied. The SLUR time delay is evaluated against the Technical Specification maximum Allowable Value (which have margins to the actual SLUR time delay settings). The most bounding motor terminal voltage is applied during the motor start, which assumes the grid voltage has decreased to a worst case voltage (specific to the motor being analyzed) and is staying at that voltage for the duration of the SLUR time delay. It should be noted that the method above is used in favor of simply using the steady-state brake horsepower values from Reference 8.3.8 Tables A. I and C.1 in order to obtain a more accurate loading for the containment spray pumps during the initial transient. AFP8A Attachment AJ to Reference 8.3.8 establishes 430 gpm as the maximum flow though P8A. Attachment A to Reference 8.3.8 gives a value of 433 brake horsepower at 430 gpm. This data is also given in Table A.1 of Reference 8.3.8. LPSI P67 A and CC P52C In Reference 8.3.8, Table A. I gives a brake horsepower of 259 for CC P52C, and Table C. I gives a brake horsepower of 394 for LPSI P67 A for the beginning of an accident. These values are deemed reasonable given the margin applied to brake horsepower by the calculation (Attachments J and T respectively for P52C and P67 A) and the fact that this calculation predicts ample margin for these motors with respect to expected SLUR time delay acceptance criteria. Software Execution The scenario above is executed for each motor listed above for a wide range of voltages using the software discussed in Section 6.0. The total SLUR time delay is varied in the model until the maximum time delay is found for which the entire range of voltages results in no protective

mMPR Calculation No.: 0098-0189-CALC-001 Revision No.: Page No.: 1 32 device trip for the scenario above. This is the maximum total SLUR time delay which the motor can tolerate for any degraded voltage. The Simulink model motorStart.slx documented and verified in Reference 8.4.1 and stored in Reference 8.4.2 uses various curves to simulate both the acceleration of the motor from rest, and the resulting effect on the protective relay for the motor. The model solves for variables iteratively at discrete time steps. The model performs the following calculations:

1.

The motor torque-speed curve used in the model corresponds to a voltage of V_mt. The voltage of the motor during the scenario is V_motor. To account for the simulated voltage, the motor torque values are scaled by a factor of: ( V_motor) 2 V_mt

2.

Motor speed and torque values form a look-up table. The initial speed of the motor for the time step is input to the look-up table, and an output motor torque is found by interpolating between the nearest two points in the look-up table.

3.

The load torque values are scaled up or down to account for the expected loading of the pump during the scenario.

4.

Load speed and torque values form a look-up table. The initial speed of the motor for the time step (same as input to motor torque table) is input to the look-up table, and an output load torque is found.

5.

Load torque (power consumed) is subtracted from motor torque (power generated) to give the driving torque for the time step, or the torque that is available to accelerate the motor.

6.

Driving torque in lbf-ft is divided by the total inertia of the rotating assembly to give the acceleration of the motor in __!!!L___ This is multiplied by 32.17 ft/ s 2 to give the lbm*ft lbf /lbm acceleration of the motor in rad/s2.

7.

The acceleration is integrated at each time step to give the speed of the motor at the end of the time step in rad/s. The initial speed of the motor for the simulation is O rad/s. The speed is then converted to RPM and supplied as an input to the motor torque curve, the load torque curve, and the motor current curve for the next time step.

8.

The motor current-speed curve used in the model corresponds to a voltage of V_mc. The voltage of the motor during the scenario is V_motor. To account for the simulated voltage, the motor current values are scaled by a factor of: V_motor V_mc

9.

Motor speed and current values form a look-up table. The speed of the motor for the time step ( output of step 7 above from the previous time step) is input to the look-up table, and an output motor current is found.

10.

Current and trip time values form a look-up table. However, the values were taken from a log-log plot, so that interpolation is most accurate iflogl O is taken of each value prior

Calculation No.: 0098-0189-CALC-OO 1 mMPR Revision No.: Page No.: 33 to being plugged into the table. This means the table is interpolating between values as they were taken from the original curve, with no distortion. The output trip time is also in log I 0, so that IO must be raised to the power of the result to get the trip time for the time step in seconds.

11.

The trip time for the time step is the time at which the relay would trip if the instantaneous current for the time step were constant. To obtain the ratio of the distance the relay traveled during the time step to the overall distance the relay must travel to trip, the trip time is inverted and integrated. This means that at each time step, the duration of the time step (0.0 l seconds) is divided by the trip time of the relay at the instantaneous current to represent the distance the relay rotated during the time step, which is added to a running total.

12.

At the end of the simulation, the final value for trip ratio indicates how far the relay rotated during the transient. The MATLAB code simMotorStart.m documented and verified in Reference 8.4.1 and stored in Reference 8.4.2 uses the Si mulink model described above to simulate the desired scenario with various degraded voltages. For each voltage ran, the Simulink model is run twice: once for the degraded voltage condition, and once for the start on the EOG. The MATLAB code uses the method presented in Section 7.1.2 to calculate the amount the relay resets during the EOG time delay. The MATLAB code has inputs from three different sources: the call line of the function in MATLAB (these are input directly to the function within MATLAB), an Excel spreadsheet containing inputs for all motors, and another Excel spreadsheet containing curves for a type of motor. Appendix E documents all inputs for each of the seven cases ran. 7.2.3 Results Appendix E presents the results of the above simulations. CS Pump P54B and AF pump P8A are particularly limiting and are discussed in more detail in Sections 7.7.1 and 7.7.2, respectively. 7.3 480V Induction Motors that Drive Pumps, Fans, Valves and Dampers 7.3.1 Scenario The bounding scenario used to evaluate the acceptability of the SLUR time delay for induction motors on the 480V buses and MCCs is shown in Figure 2. The scenario is the same as the scenario depicted in Figure 1, except there is no EOG time delay, because the motors start immediately upon transferring to the EOG after the SLUR time delay. It should be noted that the containment cooler recirculation fans on Bus 12 and the air handling unit fans V95 and V96 on MCCs 25 and 26 do experience time delays before being energized by the EOG; however, the time delay is not credited by this calculation for these motors, so they are evaluated in the same manner as the 480V loads that start instantaneously on the EOG.

Current Profile used to Evaluate SLUR Time Delay for 480V Induction Motors 7.3.2 Calculations The following calculations are performed for each individual load to determine the maximum SLUR external time delay that can be tolerated without tripping the protective device at any point in the scenario described above. Stall Current The current drawn while the motor is stalled is calculated from the following equation: where l srall is the stalled current in Amps, V% is the minimum guaranteed start voltage (and therefore maximum possible stall voltage) as a percentage of rated voltage, and hn is locked rotor current at rated voltage in Amps. Protective Device Trip Times The times at which the protective device trips at ls1a11 and hn are determined to be 11,ip_stall and lr,ip_sra,r, respectively, using the sources discussed in Section 5.7. Refer to Appendix B for details on the thermal overload curve fitting. Refer to Appendix C for details on the damage time extrapolation. All protective device trip times are taken at the most conservative value provided by the reference.

Calculation No.: 0098-0189-CALC-001 Revision No.: Page No.: Allowable SLUR Time Delay 1 35 The protective device must be able to complete the evaluation scenario (meaning the motor must be able to start) without tripping. The following equation is used to calculate the maximum allowable SLUR external time delay (lnuu at) for the motor: tmax_ext = tstall_max - tint where lstall_mm: is the maximum time the motor can stay at the stall current without the motor tripping during its start, and t;,,, is the SLUR internal time delay. lstall_nuu: is calculated as below: tstall_max = (l - Xstart)

tint tnp_start Table 11, Table 12, and Table 13 in Appendix F present the results of the above calculations. Containment Cooler Recirculation Fans VIA, V2A, and V3A are particularly limiting and are discussed in more detail in Section 7.7.3. 7.4 Battery Chargers 7.4.1 Scenario Unlike motors, battery chargers do not have a significant duration of elevated "inrush" current upon voltage recovery from degraded conditions. Reference 8.5.35 states the battery chargers are estimated to have an inrush current of 10 times full load current for 1 cycle ( l/601h of a second), reinforcing this claim. Thus, the battery chargers are evaluated against a simple scenario of degraded voltage for the duration of the SLUR time delay, neglecting any subsequent inrush.

mMPR 7.4.2 Calculations Bounding Voltage Calculation No.: 0098-0189-CALC-001 Revision No.: Page No.: 1 36 As discussed in Section 3.2, in order to evaluate the battery chargers, a limiting voltage must be determined at which the FLUR is guaranteed to trip before the SLUR. The batter chargers are connected to 480V buses. Equipment on 480V buses is commonly rated for 460V. Fifty percent of 460V (230V) is used to bound the effect of degraded voltage on the battery chargers. The transformers (XFRM No. 19 and XFRM No. 20) that separate 480V buses LC-19 and LC-20 (which ultimately supply power to the battery chargers) from 2400V buses 1 C and ID have a turns ratio of 2400/480, and the transformers that separate 2400V buses IC and ID from the FLU Rs (relays 127-1 and 127-2) have a turns ratio of 2400/120 (Reference 8.11.6), so that 57.SY at the FLUR corresponds to 230V at the 480V bus. The FLUR set point is 93V (Reference 8.11.6), so that 57.SV is 62 percent of the FLUR set point. Figure 2 in Reference 8.11.6 shows that at 62 percent of the FLUR set point, the FLUR trips in 4.4 seconds. This is much faster than the SLUR time delay, and establishes 230V as an adequate bounding voltage for use in the battery charger evaluation. The calculation above non-conservatively neglects the voltage loss that would occur due to the transformers and cables between the FLUR and the battery chargers. However, there is large margin between FLUR trip time of 4.4 seconds and the SLUR time delay (on the order of7 seconds), the analysis approach is conservative per Assumption 4.1.7, and the results presented Appendix G show the battery chargers are not close to being limiting loads in this analysis. These factors greatly outweigh non-conservatism introduced by neglected voltage losses in the analysis of the battery chargers. Current at Degraded Voltage Per Assumption 4.1.7, battery chargers act as constant power devices (decreases in voltage cause increases in current, and vice versa). Reference 8.11.7 states the AC voltage input range as 408 V AC-528 V AC, and the AC input current range as 52A-67 A. By multiplying the maximum voltage by the minimum current, the power is calculated to be 27456 VA. As discussed in Section 3.2, 50% rated bus voltage is used to calculate a bounding current for the duration of the SLUR time delay. The battery chargers are connected to a 480V bus, so 460V is used as rated voltage for conservatism. The voltage in this degraded condition is 230V. Dividing power by this value yields 119.4A. This value is rounded up to 120A for conservatism, and is referenced as Inc below. Protective Device Trip Times The time at which the protective device trips at Inc is determined to be conservatively bounded by 100 seconds using the sources discussed in Section 5.7. This value is referenced as 11,ip_Bc in the calculation below.

Allowable SLUR Time Delay Calculation No.: 0098-0189-CALC-001 Revision No.: Page No.: 37 The following equation is used to calculate the maximum allowable SLUR external time delay (t11UL-.:_e-.:1) for the battery chargers: tmax_ext = ltrip_BC - tint where t;t11 is the SLUR internal time delay. 7.4.3 Results Table 14 in Appendix G presents the results of the above calculations. 7.5 Distribution Breakers 7.5.1 Scenario The distribution breakers must be proven to not trip during the SLUR time delay while many downstream loads are drawing higher current than normal. The impact of subsequent motor starts must also be considered. Thus, the distribution breakers are evaluated against a scenario similar to that shown in Figure 2, where all loads are drawing current appropriate to degraded voltage conditions for the SLUR time delay, followed by a period of time in which motor loads are starting, and static loads are drawing rated fu ll load current. As discussed in Section 3.3, 80% voltage is used during the degraded voltage condition for the distribution breaker evaluation. 7.5.2 Calculations Load Current The total current running through each distribution breaker is calculated by summing the current draws of each load downstream of the breaker, conservatively neglecting variances in power factor from load to load. Section 5.8.1 discusses the various load types and how information is gathered for each load. It is discussed below how current during the degraded voltage condition is calculated for each of the three types of individual loads: ~ Motor Loads If locked rotor current is available for a motor load, current is simply 80% of LRA. If locked rotor current is not available for a motor load, then the rated horsepower of the motor is used to estimate a full load current. Full load current is estimated from the following equation:

Calculation No.: 0098-0189-CALC-001 mMPR Revision No.: Page No.: 38 where hp is the rated horsepower of the motor, PF is the power factor of the motor (0.8 is used for all motors), EF is the efficiency of the motor (0.8 is used for all motors), V is the rated voltage of the motor ( 460V is used for all motors), and N is the number of phases (3 for all motors). The values used for power factor, efficiency and voltage are deemed appropriate after a review of Appendices Mand N of Reference 8.3.1. Full load current is then multiplied by 7 to determined locked-rotor current (7 is deemed an appropriate ratio after a review of Appendices Mand N of Reference 8.3.1 ). After scaling LRA down to 80% voltage, the following equation is used to calculate the current of the motor at degraded voltage conditions (lDv): 10 v = 0.8

~ Mixed Loads The battery chargers evaluated individually will be assigned the same current previously used (120A). Loads that have power given in units of kV A (referred to as "mixed loads") are conservatively modeled to be fully comprised of motors. If locked rotor current is available for a mixed load, current is simply 80% of LRA. If locked rotor current is not available for a mixed load, then the rated power in kV A is used to estimate a full load current. Full load current is estimated from the following equation: p * ( 10000:) I FL - V

  • ffe where Pis the rated apparent power of the load in kV A, Vis the rated voltage of the load ( 460V is used for all loads and is consistent with the approach for motor loads),

and N is the number of phases ( 1 for some transformer feeders and 3 for the remaining loads per Reference 8.3.1 ). Full load current is then multiplied by 7 to determined locked-rotor current (consistent with the approach for motor loads, and deemed appropriate given the conservatism of the approach for mixed loads). After scaling LRA down to 80% voltage, the following equation is used to calculate the current of the motor at degraded voltage conditions (/Dv): P * ( 1000~) p 10 v = 0.8

mMPR ~ Static Loads Calculation No.: 0098-0189-CALC-001 Revision No.: Page No.: 39 Loads that have power given in units of kW (referred to as "static loads") are assumed to be constant impedance devices, with current decreasing with voltage. Any load clearly labeled as "lighting" is also considered a static load, regardless of the units of given power. The rated power of the load in kW is used to estimate a full load current, which is scaled down to 80% in response to an equivalent drop in voltage level. Full load current is estimated from the following equation: where Pis the rated real power of the load in kW, PF is the power factor of the load (0.8 is used for all loads, as it bounds power factors for static loads given in Reference 8.3. I), Vis rated voltage of the load ( 460V is used for all loads and is consistent with the approach for motor loads), and N is the number of phases (3 for all loads). After scaling down the full load current to 80% voltage, the following equation is used to calculate the current of the load at degraded voltage conditions (lvv): P * ( 1000~) fvv = 0.8

  • r::; = 1.26
  • P 0.8
  • 460
  • v3 Breaker Current Instead of using raw total current to evaluate the distribution breakers, diversity factors are applied for each bus to scale down the current to a level more similar to levels measured by the plant. The current draw of the loads of each ofthe three types discussed above are summed for each bus (conservatively ignoring any variation in power factor from load to load) and multiplied by the diversity factor for that bus, as shown below:

fsus_DV = Fviv * (hoad_l + lload_2 + ** * + hoad_N) The adjusted currents for each bus downstream of a particular distribution breaker are then summed to obtain the total current for the breaker, as shown below: lvB_DV = fsus_l + fsus_2 + *** + fsus_N For the second part of the evaluation scenario, motor and static loads are scaled up to I 00% locked rotor current and full load current, respectively. This may be accomplished simply by dividing the degraded voltage current by 80% as follows: fvs DV /DB_RV = -----0:S-

Motor Start Time For simplicity, all motors are conservatively assumed to take 4 seconds to fully accelerate, as discussed in Section 3.3. Protective Device Trip Times The times at which the distribution breaker trips at Ivn_vv and Ivn_Rv are determined to be ltrip_Dv and 11,ip_Rv using the sources discussed in Section 5.7. Allowable SLUR Time Delay The following equation (similar to that used in Section 7.3.2 for MCC motors) is used to calculate the maximum allowable SLUR external time delay (tma~_ew) for the distribution breakers: tmax_ext = [(1 - t~cc )

  • ttrip_Dv]- tint ttnp_RV where t;111 is the SLUR internal time delay, and t"cc is 4 seconds as discussed above.

7.5.3 Results Table 15 from Appendix H presents the results of the above calculations. 7.6 Fuses For starting MCC safety loads, the fuses that protect the starters must not melt during sustained degraded voltage. 7.6.1 Scenario Fuses are evaluated against a simple scenario of degraded voltage for the duration of the SLUR time delay. 7.6.2 Calculation The starter is taken to be at its pickup voltage because if voltage is higher, the contact will close and the starter wi ll no longer draw inrush current. Inrush current at rated voltage is scaled down to the pickup voltage. It is then determined whether the fuse will melt at this current, and if so, how long it wil l take. This information is compared to the results of the rest of the analysis to determine if the fuses wi ll limit the maximum allowable external SLUR time delay. 7.6.3 Results Table 17 from Appendix I presents the results of the above calculations.

7. 7 Limiting Loads Calculation No.: 0098-0189-CALC-001 Revision No.:

Page No.: 41 The following sections discuss the Containment Spray Pump P54B, Auxiliary Feedwater Pump P8A, and Containment Cooler Recirculation Fans VIA, V2A, and V3A, which are limiting loads in this evaluation. Proposed breaker overcurrent relay setting changes are analyzed for Containment Spray Pump P54B and the Containment Cooler Recirculation Fans. An alternative analysis is presented for Auxiliary Feedwater Pump P8A to provide assurance that the pump will be available in an accident scenario. 7.7.1 Containment Spray Pump P54B CS pumps P54A and P54B must start on the diesel within 2 seconds of the start of EOG load sequencing, making both pumps more limiting than CS pump P54C, because the induction disk relay for P54C has longer to reset. However, P54B has a lower overcurrent relay setting than P54A, making P54B the most limiting of the CS pumps. The three CS motors are the same, so the overcurrent relay for P54B could be changed to match the setting of P54A. This would increase the SLUR time delay that the motor could withstand. One case is run for P54B with its current relay setting, and one is run for P54B with the same relay setting as P54A to evaluate the effect of a proposed breaker overcurrent relay setting change. As shown in Table 10, P54B can withstand a total SLUR time delay of 5.9 seconds with its current relay setting, and can withstand a total SLUR time delay of7.2 seconds with the modified setting. 7.7.2 Auxiliary Feedwater Pump P8A Table 10 shows that AF pump P8A can withstand a total SLUR time delay of7.0 seconds. However, because the pump is not required to start on the EOG until 45 seconds after the SLUR has tripped, and the reset time for the relay is 9 seconds, the relay will be able to completely reset while de-energized, possibly allowing the pump to start on the EOG even if the protective overcurrent relay trips during the SLUR time delay. While this would provide assurance the pump will be available to start on the EOG, motor damage due to two sequential starts must still be considered. The following sections show that the breaker for the AF pump is allowed to close after an overcurrent trip during the SLUR time delay, allowing the motor to start, and that the two sequential starts will not thermally damage the motor. Relay Logic Breaker 152-104 controls power to Auxiliary Feed water Pump P8A. Reference 8.8.11 shows that if Connection Point 2 on the drawing is energized and the breaker is currently closed, the breaker wi II trip open. If Connection Point 1 on the drawing is energized and the breaker is currently open, the beaker will close. This drawing also shows that there is no permanent lockout or lockout requiring operator action that is preventing the closure of the breaker. The breaker has three overcurrent relays that can cause the breaker to open and trip power to the pump: the Time-Overcurrent relay (TOC), the High-Dropout relay (HOO), and the fnstantaneous Overcurrent relay (f OC) (Reference 8.5.2). The operating logic for the relays is obtained from the wiring diagram for the breaker shown on page 15 of Reference 8.5.2 and the schematic diagram in Reference 8.8.12. The IOC relay operates in parallel with the other two relays, and is

mMPR Calculation No.: 0098-0189-CALC-001 Revision No.: Page No.: 42 not considered in this analysis as currents in the evaluated scenario will be much less than the IOC setpoint. The HOO and TOC contacts are in series, so that both must actuate and close in order for the trip coil to become energized. The relay has a seal-in that is energized once both the TOC and HOO are closed, so that the trip coil will remain energized ifTOC drops out, as long as HOO is picked up. However, if HOO drops out, the breaker no longer receives a trip signal, regardless of whether TOC is picked up. Reference 8.8.13 shows that the spring release coil is energized when the 62-1 /P8A relay is energized and the 62-2/P8A relay is de-energized. Reference 8.8.14 shows that these two relays are automatic start relays and wi II allow the pump to start if a start signal is present. Given the above logic, the scenario under consideration is given below: I. Breaker 152-104 is closed and the Auxiliary Feed water Pump P8A is drawing elevated current due to a degraded voltage event.

2. The current is above both the HOO and TOC pickup setpoints. The HOO relay closes immediately as it does not have a time delay (Reference 8.5.2). The induction disk relay implementing the time-characteristic of the TOC begins to rotate toward a tripped state.
3. The TOC contact closes as the induction disk completes its rotation, energizing the trip coil of Breaker 152-104, and deenergizing the Auxiliary Feedwater Pump P8A.
4. As current goes to zero, the HOO drops out, removing the trip signal from Breaker 152-104.
5. With zero current, the induction disk of the TOC rotates back to a completely reset state.
6. With no trip signal, Breaker 152-104 is free to close once the spring release coil is energized by the closure of the 62-l/P8A relay upon a pump start signal. With a reset induction disk, the pump will be able to fully accelerate on the EOG.

Thermal Damage To determine if the motor is damaged during the scenario, a conservative I2t value at which the motor is damaged is determined from the thermal damage curve for the motor. This value is then compared to the I2t value accumulated by the motor during the scenario. Reference 8.11.1 provides a thermal damage curve for the motor. The "Locked-Rotor" damage curve is used as opposed to the "Overload" damage curve, because the motor is in a locked-rotor condition. Discrete time-current data points are taken from this curve, and an I2t value is calculated for each point. The lowest (most limiting) is taken and rounded down to the nearest thousand, resulting in an I2t value of2,436,000 that conservatively bounds damage to the motor. It should also be noted that the damage curve provided in Reference 8.11.1 is for a motor that is starting at 120°C, whereas in the scenario evaluated, the motor would be starting from ambient temperature. This provides additional conservatism. The I2t value of the motor is determined from the scenario used for static motor starts. This scenario is discussed further in Section 7.1.1. The motor is considered stalled at 70 percent motor rated voltage for the length of the total SLUR time delay, at which it will draw 70 percent

mMPR Calculation No.: 0098-0189-CALC-001 Revision No.: Page No.: 43 ofLRA (437.5A per Reference 8.5.2). 8 seconds is used for the total SLUR time delay to bound the value. The l2t accumulated by the motor during this portion of the scenario is 1,531,250. Motor cooling is conservatively neglected during the period when the motor is de-energized The motor then starts on the EOG at I 00 percent motor rated voltage, at which it will draw LRA (625A per Reference 8.5.2). The acceleration time of the motor at 100 percent motor rated voltage is 1.28 seconds (Reference 8.5.2). The I2t accumulated by the motor during this portion of the scenario is 500,000. The total 12t accumulated by the motor during the scenario is 2,031,250, which is less than the motor damage value by a margin of 16.6 percent. Therefore, the AF pump P8A motor will not be damaged due to the bounding degraded voltage scenario evaluated. 7.7.3 Containment Cooler Recirculation Fans (480V Bus 12) Containment cooler recirculation fans VI A and V3A are limiting because of the calibration procedure for the setting of the device. The calibration is performed by running 300A through the relay and measuring the time it takes the device to trip. The nominal setting of the device corresponds to a calibration trip time of 20 seconds, while any time between 7 seconds and 35 seconds is deemed acceptable (Reference 8.5.24). Because it is al lowed by the calibration procedure, the most limiting trip curve corresponding to a calibration trip time of7 seconds must be used, resulting in allowable SLUR external time delays of less than 2 seconds (Table 11, Appendix F). Because the nominal calibration time is 20 seconds, these results are not likely representative of the devices as they stand in-service. If the lower limit to the calibration trip time were increased in the calibration procedure, the allowable SLUR external time delay could be raised. The following calculation determines the necessary lower limit to calibration time. The protective devices for the two motors are identical per References 8.5.24 and 8.5.26. Table 11 in Appendix F shows the two motors have the same parameters with the exception of start time, which is higher for V3A. As such, the new lower limit to the calibration trip time is calculated for V3A as the most limiting motor, and applied to both motors. Below is a modified version of the equation used to calculate the allowable SLUR external time delay for 480V induction motors (Section 7.3): tmax_ext = [(1 -. tacc x) * ( ttrip_stall_7

  • x)]- tint ttnp_start_7
  • where l1,ip_s1a,t_7 and l1,ip_s1al/_7 are the trip times of the device as set by a calibration time of 7 seconds, and Xis the amplification factor applied to the trip times as a result of an increase in the calibration trip time. Xis equal to the ratio of the new calibration trip time to the old 7 second calibration trip time per Assumption 4.1.14. Solving for X yields:

tmax ext + tint tacc 6.5 + 0.8 2.28 X = + = +-- = 2.1 ttrip_stall_7 ttrip_start_7 4.8 4.1 where 6.5 seconds is used as the desired SLUR external time delay, and trip time and acceleration time values are taken from Table 11. A value of2.1 for X yields a new lower calibration trip time of 14.7 seconds. This value is rounded up to the nearest second, so that the

Calculation No.: 0098-0189-CALC-001 mMPR Revision No.: Page No.: 44 new lower calibration trip time is 15 seconds. The new allowable SLUR external time delay for the V3A motor is calculated below: tmax_ext = [(1 - 2 2~) * ( 4.8

  • 1;)]- 0.8 = 6.8 seconds 4.1
  • 7 This change would allow Containment Cooler Recirculation Fans VI A and V3A to withstand a SLUR external time delay of 6.8 seconds.

mMPR Calculation No.: 0098-0189-CALC-001 Revision No.: Page No.: B-1 8 THERMAL O VERLOAD HEATER BEST-FIT CURVES Table 5 contains the overload heater trip time data used to generate the best-fit curve for the G30T family of heaters (manufactured by ITE) shown in Figure 3. Table 6 contains the overload heater trip time data used to generate the best-fit curve for the CR123C family of heaters (manufactured by GE) shown in Figure 4. Both best-fit curves are of the form: where y is trip time in seconds, xis per unit current (current normalized by the ultimate operating point of the heater), and A and n are constants. For the G30T heaters, the curve fit results in A as 53.7 and n as -1.136. For the CR l 23C heaters, the curve fit results in A as 73.1 and n as -1.148. Both curve fits have R-squared values greater than 0.99. However, extra conservatism is applied to trip or damage times calculated using this method.

The breaker setting calculations referenced provide the information in this table while going through the process of selecting an appropriate heater. The calculations select a heater and compare trip times at various currents to motor damage points. If a heater fails to protect the motor at any of the evaluated currents, the calculation moves on to a smaller heater. As such, some calculations provide data on multiple heater sizes.

mMPR C MOV DAMAGE TIME EXTRAPOLATION Calculation No.: 0098-0189-CALC-001 Revision No.: Page No.: C-1 There are 10 MO Vs (with alarming thermal overloads) for which Assumption 4.1.9 does not provide enough margin for the evaluation. These MO Vs are separated into two identical motor types (as confirmed by a review of each MO V's breaker setting calculation): Type A: Consists of motors corresponding to breaker numbers 52-2113, 52-2139, 52-2239, 52-2339, 52-2413 and 52-2439. Type B: Consists of motors corresponding to breaker numbers 52-2129, 52-2229, 52-2329 and 52-2429. A review of the motor damage data provided in References 8.5.61 and 8.5.64 (as representative references for Type A and Type B motors, respectively) show that motor damage times for both motor types are inverse exponential with respect to current. This means that as current decreases, damage time increases exponentially. Each damage curve may be bounded below by a line that goes through two points on the damage curve. The two points from which the line is generated must be at higher currents than those for which the line will estimate damage time to ensure the damage curve is properly bounded. For Type A motors, Reference 8.5.61 gives one damage point at 25.3A and 8.2 seconds, and another at 27.2A and 6. 77 seconds. The following calculations detennine a bounding trip time at 70% LRA for Type A MOVs (percent voltage per Section 5.4.3): 6.77s-8.2s s Slope = 27.2A - 25.3A = -0.75 A Y - intercept= [C-25.3A) * (-o.75~)] + 8.2s = 27.2 seconds ttrip_stau = [(0.7

  • 25.3A) * (-0.75~)] + 27.2s = 13.9 seconds For Type B motors, Reference 8.5.64 gives one damage point at 59.7 A and 8.75 seconds, and another at 62.3A and 7.23 seconds. The following calculations determine a bounding trip time at 70% LRA for Type B MOVs (percent voltage per Section 5.4.3):

7.23s - 8.75s s Slope = 62.3A - 59.7 A = -0.5S A Y-intercept= [C-59.7A) * (-0.58 ~)] + 8.75s = 43.4 seconds ttrip_stall = [(o.7

Notes for Table 7: Calculation No. : 0098-0189-CALC-001 Revision No.: Page No.: 0-2 I. The time each motor sits on a dead bus before being energized by the diesel after an accident is found in Tables 5-1 and 5-2 of Reference 8.3.3 (see Section 5.4.2).

2. The reset time for each motor is determined by multiplying 6 seconds by the time dial setting of the GE IAC66K relay (discussed in Section 7.1.2).
3.

The limiting condition of the motor refers to whether the critical point (point in time of the scenario discussed in Section 7.1.1 when the protective device is closest to, or furthest past, tripping) is at the end of the SLUR time delay ("Motor Stall"), or the end of the motor accelerating ("Motor Start"). If the EOG time delay is greater than the critical EOG time delay, which is calculated as (tacclt1,;p_star1)*treset, the motor is stall-limited. If the opposite is true, the motor is start-limited.

4.

The maximum allowable SLUR external time delay for each motor is calculated depending on the limiting condition as discussed in Section 7.1.2. Values are rounded down to the nearest tenth of a second.

5.

All 2400V motors have a minimum guaranteed start voltage of 70% rated voltage (see Section 5.4.3).

6. Parameters obtained from each source are in parenthesis next to the source. Parameters include locked rotor current (LRA), motor acceleration time (AT), and protective device trip times at stalled conditions (TT1) and start conditions (TT2).

The reference gives flow in lbm/hr for the containment spray pumps. The reference uses a density of 62.147 lbm/ft3 (see Section 7.2.2 Pump Loading). This density is used to convert mass flow to volumetric flow.

2. These values are obtained by using linear interpolation between the nearest two data points in the tables provided by the reference.

Flow cbm)*Head

3. Brake horsepower is calculated for the containment spray pumps using the formula hr

, as Eff*l,980,000 discussed in Section 7.2.2 Pump Loading.

4.

Brake horsepower is simply taken from the reference for these pumps, so head and pump efficiency are not required.

mMPR Notes for Table 9: Calculation No.: 0098-0189-CALC-001 Revision No.: Page No.: E-1 3

1. There are three types of inputs to simMotorStart.m: those inputs directly into the function call line, those provided in the inputs spreadsheet, and those provided in the curves spreadsheet.
2. Descriptions for each input are provided in Reference 8.4.1.
3.

For input curves, the filename and tab name are given where the curve can be found within Reference 8.4.3.

4. The torque and current curves used for P8A are for a motor that is no longer in service. However, as indicated in Reference 8.5.2, the motors are very similar. Furthermore, the full load current for the new motor is lower than the old, so using the curves from the old motor is conservative.
5. The only torque-speed and current-speed curves found for LPSI P67 A were 100 percent voltage curves. These curves are scaled for the degraded voltage transient, and used for the EOG start transient.

Outputs The spreadsheet containing the results of all seven runs is stored in Reference 8.4.3. The results of each case are plotted in the following figures. For each case, the trip percentage reaches a peak very close to I 00 percent, but does not cross the 100 percent I ine shown. This shows that the time at which the simulation was run is the maximum acceptable total SLUR time delay for the motor, as a longer time delay would cause the relay to trip. 105 100 QJ bO +-' 95 C QJ ~ QJ Cl.. 90

mMPR Notes for Table 11: Calculation No. : 0098-0189-CALC-001 Revision No.: Page No.: F-4 I. All 480V motors have a minimum guaranteed start voltage of 80% rated voltage (see Section 5.4.3). However, the testing documented in Reference 8.11.11 shows the motor for Containment Cooler Recirculation Fan V2A can start at 70% rated voltage, so this reduced voltage is used for the V2A motor only.

2.

For loads that use Assumption 4.1.10 or 4.1.11 to estimate trip times, the operate current of the thermal overload (which is used to convert current from per unit to Amps) is given in the breaker setting calculation for the load unless otherwise stated.

3.

The maximum allowable SLUR external time delay for each motor is calculated as discussed in Section 7.3.2.

4.

The ultimate operating current for the heaters of these loads is determined to be 34A by using 125% of the minimum full load motor current listed in Table 6 on pg. 2-57 of Reference 8.11.5 (a method that is concurrent with Reference 8.5.90 and other breaker setting calculations). A maximum starter size of 2 is used, and 3 relays are used. The heater number is G30T49A. This information is also documented in Assumption 4.1.13.

5.

Parameters obtained from each source are in parenthesis next to the source. Parameters include locked rotor current (LRA), motor acceleration time (AT), and protective device trip times at stalled conditions (TT1) and start conditions (TT2).

6.

Containment Cooler Recirculation Fans V1A and V3A do not allow for a reasonable SLUR time delay. A path to resolve these motors is presented in Section 7.7.3.

7.

The time characteristic curve for the overcurrent relay for Containment Cooler Recirculation Fan V2A shown in Reference 8.5.25 includes a tolerance band that is meant to repr~sent the acceptance criteria used when calibrating the relay. A test is run where the relay is subjected to 330A, and the relay must trip in 15 to 34 seconds in order to be placed in service. However, the lower limit of the curve corresponds to a calibration time of 7 seconds (the previous minimum allowable value) rather than 15 seconds. To correct for this, trip time values are taken from the lower limit of the curve and multiplied by 15/7 to obtain the trip time corresponding to a calibration time of 15 seconds.

5.

Motor damage times are used in place of protective device trip times for t,,;p_start and t1,;p_s1a11 for loads on these MCCs, because the thermal overloads only alarm and trip times are overly conservative.

The ultimate operating current for the heaters of these loads is determined to be 0.401 A by using 125% of the minimum full load motor current listed in Table 6 on pg. 2-57 of Reference 8.11.5 (a method that is concurrent with Reference 8.5.90 and other breaker setting calculations).

5.

The locked-rotor Amps of 2.18 provided in the breaker setting sheet referenced contradicts the value of 3.15 Amps provided in the EDSA model calculation (Reference 8.3.1 ). The value from the EDSA model is an assumed value, and appears to be highly conservative. Therefore, 2.18 Amps is used in this evaluation. However, 3. 15 Amps is used in the distribution breakers analysis shown in Table 16.

Notes for Table 16: Calculation No.: 0098-0189-CALC-001 Revision No.: Page No.: H-12 I. Possible load types are: "hp" for motor loads, "kVA" for mixed loads, "kW" for static loads, and "MCC" for loads comprised of one or more entire MCCs.

2. Either a power value or a locked rotor current value (but not both) is used to calculate degraded voltage current for each load. Section 5.8.1 discusses how these values are chosen.
3.

Power is in units of horsepower, kVA, or kW depending on the load type.

4.

The method for calculating the degraded voltage current of each load depends on the load type and whether LRA or power is used, as discussed in Section 7.5.2.

5.

These loads represent MCCs that are broken into individual loads elsewhere in the table. The current is simply a sum of the individual loads in the MCC(s) as shown in this table.

6.

These loads are 1 phase transformers and current is calculated accordingly. All other loads are 3 phase.

7.

The current draw of the battery chargers is discussed in Section 7.4.

8. These loads are intermittent and are neglected for the purposes of this evaluation.
9.

Power values for these loads are given in kVA in the reference. However, this evaluation treats lighting loads as static (kW load). For these loads, power factor is removed from the equation used to calculate the current of a kW load (discussed in Section 7.5.2) because power is already in kVA. I 0. Parameters obtained from each source are in parenthesis next to the source. Parameters include locked rotor current (LRA) and power (PWR).

Loads included in this list are starting safety loads on MCCs. The list is compiled from the intersection of the MCC loads specified to start in Table 7.5.2-3 of Reference 8.3.2, and MCC loads specified as safety related in Reference 8.10.1.

2. Starter manufacturer, size, and model are taken from Appendix A of EA-ELEC-VOL T-050 (Reference 8.3.5). Starter pickup voltage (as a percentage of rated voltage) and rated inrush current are used to calculate current draw and are taken from Appendix Hof EA-ELEC-VOL T-050 (Reference 8.3.5).
3.

The current draw of the starter is the rated inrush current scaled down to pickup voltage, or inrush current multiplied by the fractional pickup voltage. This value must be less than the melt current for both the associated fuse and backup fuse.

4.

Fuse manufacturer, model, and rating are taken from Appendix A of EA-ELEC-VOL T-050 (Reference 8.3.5).

5.

Reference 8.11.9 gives vendor information on the Bussman model NON fuses. These fuses are "One-Time" fuses and will not melt if current is below the fuse rating. Reference 8.11.8 gives vendor information on the Bussman model FRN-R fuses. These fuses are specified to "hold an overload which is five times greater than the ampere rating of the fuse for a minimum of ten seconds," so that if current is below five times the rating of the fuse, the fuse is guaranteed not to melt for ten seconds. Reference 8.11.10 relates Reliance ECN and ECNR fuses to Bussman FRN-R fuses, so that they may be treated in the same manner.

Design Objective: (Attach additional sheets as reguired} With a stopwatch, measurements of the motor start time for V-24B was made through the noise the turning fan made. Two starts were measured. One start was measured at 1. 7 seconds. The second start was measured at 1.4 seconds. This was a crude method of measuring the motor start times but the inaccuracy of the method is small enough to say that the start times are less than 3.0 seconds. This value of the start time for V24B would be applicable to the start time for the other Diesel Generator fans; V24A, V24C, and V24D.

RE: Safety Classification of Components

Jonathan, Would 10:00 tomorrow work for you for a phone call? If so, you can call Kirk's phone, 269-764-2521.

Also, I talked with the system engineer on the motors to P-SSA and P-558 and he agreed the motors are not Safety Related. He was aware of the need to change the classification on the motors and will do so when time allows. The loads identified as "QP" are not within scope. You are correct that these items have Augmented Quality requirements but are not Safety Related.

RE: Safety Classification of Components EXTERNAL SENDER. DO NOT click links if sender is unknown. DO NOT provide your user ID or password.

Dave, Please let me know what time works for a phone discussion today or tomorrow (my schedule is open both days).

Also, looking briefly at the list you provided I noticed that Charging Pump P-SSC was NSR but Charging Pumps P-SSA and P-558 were SR. I was under the impression from previous work that all charging pumps were NSR, so I wanted to confirm what you sent was correct. Also, I want to confirm that loads identified as "QP" are not within our scope (I assume this means they have Augmented Quality requirements but are not SR).

Thanks,

Safety Classification of Components

Jonathan, Attached is a Design Input Record (DIR} and attached Excel spreadsheet that shows the safety classification of components that are part of the Degraded Voltage analysis. As discussed earlier, the focus of the analysis can be on those components that are Safety Related (SR).

- 40 15 288 20 - 80 25 288 CHARACTERISTICS INDUCTION UN IT The induction unit consists of a conducting disk that passes through the poles of a permanent magnet and an electromagnet. The disk is free to rotate with a vertically suspended shaft, but is restrained in one direction by a spring. When energized with an alternating current of proper magnitude (set by the tap position'. the electromagnet produces out of phase fluxes at its pole faces. These fluxes interact with induced currents in the disk to produce a torque on the disk. When this torque exceeds the restraining force of the spring, the disk begins to rotate at a speed determined by the magnetic dragging action of the permanent magnet. A post attached to the rotating shaft travels a specific distance (set by the time dial). and makes electrical contact with a fixed member. Figure 1 gives the time for the induction unit to close its contacts for various multiples of pickup current and time dial sett i ngs. The time required for this unit to reset from contact closure to the Number 10 time dial position is approximately 60 seconds. Burden data for induction unit coils is listed in Table V. The impedance values are for the minimum tap. The impedance for other taps at pickup current (tap rating) varies (approximately) inversely to the square of the current rating. The following equation illustrates this: Impedance of Any Tap at Tap Amps ( _M_i n_1_* m_u_m_T a_.p_Am__._p_s ) 2 X Tap Amps 6 ( Impeda nee at) Minimum Tap

  • Provides motor overload, ground fault and short-circuit protection.
  • Helps protect motors against burnout from overloads.
  • Helps protect motors against burnout from single phasing on three phase systems.
  • Simplifies and improves blackout prevention (selective coordination).
  • Dual-element fuses can be applied in circuits subject to temporary motor overloads and surge currents to provide both high performance short-circuit and overload protection.
  • The overload element provides protection against low level overcurrent of overloads and will hold an overload which is five times greater than the ampere rating of the fuse for a minimum of ten seconds.
