Description of Revision (list changed pages when all pages of original analysis were not changed): "

This calculation evaluates the Joss of voltage (LOV) relay setpolnt during a sustained degraded voltage event.

The normal (non-accident) time delay associated with Iha second-level undeivoltage relays (degraded voltage relays) could allow the voltage at the 4.16 kV buses to remain at low levels for an extended period of time (332.3 seconds) before transfer of all safety-related loads to the emergency diesel generators. This calculation

  • evaluates the LOV relay setpoint to ensure that the safety-related motors that may be running during normal conditions will continue to operate during a sustained degraded voltage event.

I Analysis No. QDC-6700-E-2173 Revision 000 PAGE 3of18 I 1.0 PURPOSE The purpose of this calculation is to evaluate the loss of voltage (LOV) relay setpoint during a sustained degraded voltage event. The normal (non-accident) time delay associated with the second-level undervoltage relays (degraded voltage relays) could allow the voltage at the 4.16 kV buses to remain at low levels for an extended period of time. This low level of voltage could last as long as 332.3 (324+8.3) seconds (Ref. 4.2.1) before transfer of all safety-related loads to the emergency diesel generators. This calculation evaluates the LOV relay setpoint to ensure that the safety-related motors that may be running during normal conditions will continue to operate during the 332.3 second time delay without stalling or being damaged. This calculation will determine new analytical limits for the LOV relay.

Basis: The existing ETAP model (Input 2.5) shows RHRS Emergency AHU 1A operating at rated horsepower (100% loading). The actual load on the RHRS Emergency AHU 1A motor was measured at 6.21 HP per WO 0478721 (Ref. 4.3.2), which is less than 84% of the motor rated 7.5 HP. Additionally, the remaining RHRS Emergency AHU's (18, 2A, and

28) are modeled in the existing ETAP model at 84% of rated horsepower.

All four RHRS Emergency AHU motors have similar fan loads and therefore the loading for RHRS Emergency AHU 1A can be modeled in ETAP at 84% of rated horsepower.

3.2.2 It is assumed that Core Spray Emergency AHU 1B can be modeled as operating at 88% of rated motor horsepower.

Basis: The existing ETAP model (Input 2.5) shows CS Emergency AHU 18 operating at rated horsepower (100% loading). Current readings were taken on CS Emergency AHU 18 per WO 01388989 (Ref. 4.3.3) and the highest measured phase current was 4.8 A, which is 74% of the 6.5 A motor rated current. Conservatively assuming a maximum 110% motor voltage with the measured value of current results in less than 88%

loading (1.1x0.74=81.4%). Additionally, the remaining CS Emergency AHU's (1A, 2A, and 28) are modeled in the existing ETAP model at 88%

of rated horsepower. All four CS Emergency AHU motors have similar fan loads and therefore the loading for CS Emergency AHU 1B can be modeled in ETAP at 88% of rated horsepower.

3.3 Engineering Judgments 3.3.1 The results of the transient EOG voltage dip analyses from diesel loading calculations 9390-02-19-1, 9390-02-19-2, and 9390-02-19-3 are used in this calculation. The Unit 1, Unit 2, and 1/2 diesel loading calculations are not maintained and have been superseded by ETAP calculation QOC-6700-E-1503; however, the ETAP calculation only calculates the steady state EOG loading and does not carry forward the transient EOG voltage dip analyses. The calculated worst case EOG voltage dips were based on the starting of large motors during both LOOP/LOCA and LOOP without LOCA and based on the running load at the time of the motor starts. The results of the transient voltage dip analyses from the diesel loading calculations are used in this calculation as the loading on the EOGs and the sequence of automatic large motor starts seldom change.

Furthermore, an exact value for the transient voltage dip is not needed as

03.7.696-7.00. (See last page of Attachment A for ETAP Audit Trail Information) 6.0 METHOD OF ANALYSIS This analysis will evaluate the safety-related motors that may be running during normal conditions during a severely degraded voltage condition that lasts for an extended period of time. The maximum normal (non-LOCA) degraded voltage time delay is 324 seconds for the DVR timer following the 8.3 seconds DVR time delay (Ref. 4.2.1 ). Therefore, the 4.16 kV bus voltage may drop below the DVR minimum allowable value but remain above the loss of voltage relay setpoint for as long as 332.3 (8.3+324) seconds. This analysis ensures that the safety-related motors that may be running during an extended degraded voltage event do not stall or trip due to thermal overload relay operation. The motor control circuits are evaluated. Finally the LOV relay settings are evaluated to ensure that

  • the relays due not spuriously operate during expected voltage transients.

6.1 Motor Stall Voltage Calculation The torque developed by a motor is proportional to the square of the voltage (Ref.

4.5.1 ). Based on this relation, Equation 1 is derived and used to determine the minimum motor voltage to preclude motor stalling:

2 Vmotor OC Tmotor (Ref. 4.5.1) 2 Vstall ) T1oad

(

Vrated = Tbreakdown V:rated Vstall = , _Ttoad

...................._ X Tbrealcdown Equation 1 Where:

Vstall = Minimum motor terminal voltage to preclude motor stalling Vrated = Rated motor voltage T1oad = Load torque of the motor (proportional to the motor BHP)

Tbreakdown = Breakdown torque of the motor 6.2 Motor Terminal Voltage Evaluation The safety-related motors that may be running during normal conditions are first evaluated using the existing LOV relay settings, and then using new settings if necessary. The existing LOV relay setpoint was chosen such that it is bounded by the analytical limits plus the total error (Ref. 4.1.1 ). For the purpose of the motor stalling evaluation, this calculation will also consider time-voltage characteristics of the relay. The LOV relay operating time is not defined at the nominal setpoint.

Therefore, for a given setting, the time-voltage curves are used in order to determine a dropout voltage with a defined operating time.

l Analysis No. QDC-6700-E-2173 Revision 000 PAGE 9of18 l The station ETAP model (Input 2.5) is used to determine the downstream motor terminal voltages (for the motors identified in Input 2.3) with the 4.16 kV ESS buses fixed at the LOV relay setpoint (including the total error and time-voltage characteristics). The ETAP model (Input 2.5) is evaluated with the 4.16 kV ESS Buses (13-1, 14-1, 23-1, and 24-1) fixed at the LOV relay setpoint (including the total error and time-voltage characteristics). An infinite bus is connected to each of the four 4.16 kV ESS Buses in order to model a specific operating voltage. For each of the safety-related motors that may be running during normal conditions, a fictitious bus is added between the motor and its equipment cable in ETAP. These fictitious buses are needed to represent the motor terminals so that the motor terminal voltages appear in the ETAP load flow output reports. The fictitious buses are named using the motor load name with "-T" added to the end. The Unit 1 motor terminal voltages are evaluated using Scenario 1M1 SPLITLTCM, and the Unit 2 motor terminal voltages were evaluated using Scenario 2M1 SPLITLTCM from the ETAP calculation (Ref. 4.1.2). These scenarios model the normal Unit 1 and Unit 2 loading during Mode 1, split bus operation. The scenarios are modified by opening breakers to isolate the non-safety related buses such that only the 4.16 kV ESS busses and connected downstream buses are energized. The motor terminal voltages are compared to the minimum voltages required to preclude motor stalling for acceptability.

6.3 Motor Protective Device Evaluation The thermal overload (TOL) relays for the safety-related 480 V MCC motors that may be running during normal conditions are evaluated. The motors are protected by CR124 thermal overload (TOL) relays with non-ambient compensated CR123 TOL heaters. There are no normally running, safety-related 480 V switchgear motors or 4.16 kV switchgear motors. Calculation QDC-7800-E-0612, Rev. 002 (Ref. 4.1.6) selects the thermal overload heaters for the Reactor Building continuous duty motors required for operation during a LOCA. In order to ensure that safety-related loads are available, this calculation further evaluates the existing 460 V motor TOLs to ensure that they will not trip during a sustained low degraded voltage condition, which would prevent the loads from performing their intended safety functions.

The TOL trip curves are compared to the running motor currents (at tow voltage) to ensure that no TOL relays will trip on overload in less than 332.3 seconds, which is the maximum DVR time delay (Input 2.6). The TOL relay tripping characteristics are shown on GE Drawing 231HA165 (Ref. 4.4.4). On this drawing,

. the trip curves do not extend to less than 150% of the ultimate trip current for the heater, and therefore tripping times for slight overload conditions cannot be determined. by reading the curves directly. Per NES-EIC-10.02, Rev. 000 (Ref.

4.3.5) and NES-EIC-10.03, Rev. 000 (Ref. 4.3.6), a thermal overload relay operates as a constant 12T device. Therefore, the thermal energy developed during a degraded voltage condition, in terms of t2T, is compared to the 12T of the TOL relay. The TOLs are adequately sized if the following condition is met, shown in Equation 2:

For low levels of motor overload current that persist for an extended period of time, as is the case during a sustained degraded voltage condition, some of the heat generated in the TOL heater will have time to dissipate to the environment.

As a result, the actual tripping time of a thermal overload relay, at these low levels of overload current, will be longer than what is determined by using the constant 12T value. This adds further conservatism to the results.

The TOL heater 12T values are determined using the methodology in NES-EIC-10.02, Rev. 000 (Ref. 4.3.5). Data points are read from the minimum trip curves, for each tripping zone, to calculate the 12T value of each TOL. There are slight variations in the values calculated for each data point due to inaccuracies in reading the curve and therefore the lowest calculated 12T value is used for conservatism. The TOL relay tripping curves and tripping zones for each TOL heater are shown on GE Drawing 231 HA165, Sheets 2 and 3 (Ref. 4.4.4) and the ultimate trip currents (UTC) are obtained from Calculation QDC-7800-E-0612, Rev. 002 (Ref. 4.1.6). The 12T value for each data point for each TOL heater is calculated using the following equation.

2 Thoi = (lp.u. x UTC) 2 x Time Equation 3 The motor running currents at degraded voltage are calculated by considering the motors as constant kVA devices. As voltage decreases, the current will increase proportionately. Since the product of the motor power factor and efficiency can be closely approximated as a constant value, the motor current will vary in proportion to the loading. Therefore, the motor current is multiplied by the ratio of brake horsepower to rated horsepower. The motor current at degraded voltage is calculated using the following equation.

6.4 Motor Control Circuit Evaluation The motor control circuits for the safety-related 480 V MCC motors that may be running during normal conditions are evaluated to ensure that reduced voltages would not cause the motors to drop out due to contactors dropping out or due to blown control circuit fuses.

I Analysis No. QDC-6700-E-2173 Revision 000 PAGE 11of18 I 6.5 Transient Voltage Dip Evaluation As described in Section 6.2, new LOV relay settings may be required to ensure that safety-related motors have adequate voltage during a severe degraded voltage condition. The voltage transient during a LOCA block start for Unit 1 and Unit 2 is evaluated to ensure the LOV relays due not spuriously actuate. Since the LOV relays are active when the 4.16 kV ESS buses are aligned to the emergency diesel generators (EOGs), the relays must not drop out for any expected EOG voltage transient. Therefore, the voltage transients due to large motor starts during a Loss of Offsite Power (LOOP) both with and without a Loss of Cooling Accident (LOCA) event are evaluated.

6.6 Coordination with Protective Devices The timing characteristics of the LOV relays (Ref. 4.4.2) are compared to the timing characteristics of the 4.16 kV ESS bus overcurrent protective relays (Refs.

4.4. 5-4.4. 7). Specifically, the fault clearing times of the protective relays feeding the motors on the 4.16 kV ESS buses and feeding the 480 VESS transformers are evaluated to ensure that a fault will be cleared before the LOV relays dropout on low voltage.

6. 7 Determination of Analytical Limits The existing LOV relay analytical limits are based on the existing nominal setpoint with a plus or minus 5% tolerance. The LOV relay voltage new analytical limits will be based on the nominal setpoint evaluated in this calculation, plus or minus 5%.

7.0 ACCEPTANCE CRITERIA 7 .1 The setpoint for the loss of voltage relays must be high enough to prevent the stalling and tripping (due to thermal overload relay operation) of the safety-related motors that may be running during normal conditions and low enough to prevent spurious operation due to expected voltage transients.

8.0 CALCULATIONS AND RESULTS 8.1 Motor Stall Voltage Calculation The minimum motor terminal voltage to preclude motor stalling is calculated using Equation 1 from Section 6.1 and using the motor data from Input 2.4. Since the motor BHP is proportional to the torque, the BHP (in percent of rated HP) will be used for the load torque (in percent of full load torque).

In order to take into account the timing characteristics of the relay, the vendor time voltage characteristic curves are used for the motor evaluation. The existing GE IAV69 LOV relay nominal setpoint is 90% of the 93V tap (Input. 2.1 ). Based on the IAV69 relay time-voltage curves in the vendor manual (Ref. 4.4.2), the relay operating time is not defined at the nominal setpoint. The time-voltage curves show that the 90% time-voltage curve is defined for voltages between 0% (at 2.1 seconds) of tap value and 86% (at 11 seconds) of tap value (Ref. 4.4.2). The highest defined point on the curve (86% at 11 seconds) is used in order to have a defined operating time associated with the relay operation. The total negative error for the LOV relay is 2.25Vand the PT ratio is 35:1(Input2.1). Therefore, the 4.16 kV ESS bus voltage used in ETAP for the motor evaluation is calculated as follows:

V@ns = ((OViap

  • 86%)- Error] X PT Ratio V@us = [(93V x 86%) - 2.25V] x 35 = 2720V (Note that the value above is conservatively rounded down to the nearest volt.)

The ETAP model (Input 2.5) is evaluated with the 4.16 kV ESS Buses (13-1, 14-1, 23-1, and 24-1) fixed at a voltage of 2720 V. The ETAP Load Flow Output Reports are included in Attachment A. A review of the motor voltages in the load flow reports shows that the motors have either marginal voltage or insufficient voltage to preclude stalling with the 4.16 kV ESS at 2720V. The results are shown in the following table on the next page.

Per the IAV69 relay vendor manual {Ref. 4.4.2} the next available setting, utilizing the same 93V tap, is 95% of 93V (93V*95% = 88.35V setpoint}. The 95% time-voltage curve is defined for voltages between 0% {at 1.1 seconds} of tap value and 90% (at 7 seconds) of tap value. The highest defined point on the curve {90% at 7 seconds) is used for the evaluation. The total negative error for the LOV relay is 2.25V and the PT ratio is 35:1 (Input 2.1 }.

Therefore, the 4.1'6 kV ESS bus voltage used in ETAP for the motor evaluation is calculated as follows:

Per Input 2.6, the maximum normal (non-LOCA) degraded voltage time delay is 8.3 seconds for the DVR time delay plus 324 seconds for the external DVR timer, for a total time of 332.3 seconds. Therefore, the TOL trip curves are compared to the running motor currents {with the 4.16 kV ESS buses operating at 2850V) to ensure that no TOL relays will trip on overload in less than 332.3 seconds, which is the maximum DVR time delay.

During a loss of voltage event that does cause the LOV relays to dropout, the running motors may briefly stall before the degraded voltage source is disconnected from the buses. The time delay associated with the LOV relay is dependent on the level of undervoltage. It was shown above that no motors will stall and that the TOLs will not trip when the 4. 16kV ESS buses were at voltages above 2850V. The time-voltage curve of the LOV relay was evaluated in Section 8.2 and a voltage of 2850 V was derived in order to evaluate a voltage that had a defined relay operating time associated with it. The value of 2850V corresponded to relay operating time of approximately 7 seconds. In order to provide margin for any timing tolerances, which are not published by the vendor, a time of 1O seconds is assumed where the motors may stall before the LOV relays dropout.

The motors would be available to restart once the buses were repowered by the EDGs as long as no TOL relays tripped on overcurrent. Therefore, the TOL trip curves are compared to the motor locked-rotor current to ensure that no TOL relays will trip in less than 10 seconds. This is conservative because the motor current during a stall at reduced voltages will be lower than locked-rotor current at rated voltage. Based on GE Drawing 231 HA165, Sheet 2 (Ref. 4.4.4), the minimum trip current for Zone B TOL heaters, at 1O seconds, is 635% of the ultimate trip current. The minimum trip current for Zone C TOL heaters, at 10 seconds, is 785% of the ultimate trip current. The TOL heaters are evaluated in

As shown in the table on the next page, the minimum trip current for all TOL heaters is greater than 1000% of motor full load current.

8.4 Motor Control Circuit Evaluation The motor control circuits, for the safety-related 480 V MCC motors that may be running during normal conditions, are powered from control power transformers (CPTs) off the MCCs. Therefore, the degraded voltage at each MCC will result in a corresponding reduction in control power voltage. For the GE 100 line starters (Size 1) used in the MCCs for the motors being evaluated, the pick-up voltage is 85% and drop out is 63% of the 11 SV coil rated voltage (Refs. 4.1. 7-4.1.9). The turns-ratio of the control power transformer in each circuit is approximately 3.8.

The affected motors are fed from MCCs 18-1A, 19-1, 28-1A and 29-1. As seen from the ETAP analysis (see Attachment A), the lowest voltage at MCCs 18-1A, 19-1, 28-1A and 29-1 is 280 V. Neglecting the voltage drop through the CPT and control cables, the minimum required MCC voltage to prevent contactor dropout would be approximately 276 V (63% x 115V x 3.8 = 276V). This leaves approximate Iy 1V ( V1t1cc-Vmin . = 280V-276V = 1.0SV) of margin . fo r voltage drop CPT Turns Ratio 3.8 within the control circuit. Since the power requirement of the contactor during holding is small compared to the power requirement during energization, it is expected that the control circuit voltage drop will be small, but this would need to be further evaluated due to the available voltage margin. However, without further evaluating the control circuit, if decreased voltage at the MCCs did cause the contactors to dropout, all motors would be automatically available for restart once voltage was restored. Therefore, no further evaluation is performed.

The contactor coils would not be damaged due to decreased voltage. The control circuit for each motor includes a contactor in series with a temperature switch, and in some cases, an interposing auxiliary relay, which provides alarm functionality only {Refs. 4.6.1-4.6.2). The MCC voltages are below the pick-up voltage for the contactor coils, which may prevent a motor from starting, but the contactor coil would not be damaged during a low degraded voltage condition. Since the contactor would not pick-up, the associated load would not energize and not see a starting transient. None of the control circuits contain fuses, and therefore there is no risk of motors being unavailable due to blown fuses.

  • 8.5 Transient Voltage Dip Evaluation Section 8.2 determined a new LOV relay setpoint required to ensure that safety-related motors do not stall. This new setpoint is further evaluated to ensure that

I Analysis No. QDC-6700-E-2173 Revision 000 PAGE 17of18 I the LOV relays will not spuriously dropout for any expected voltage transient.

The LOV relays must not dropout for any expected EOG voltage transients. Diesel generator loading calculations 9390-02-19-1, 9390-02-19-2, and 9390-02-19-3 (Refs. 4.1.3-4.1.5) determined the largest expected voltage transients due to large motor starts on the EDGs. The calculations analyzed both LOOP/LOCA and LOOP without LOCA scenarios. The calculation results, for each EOG during the LOOP/LOCA scenario, show that the voltage recovers to more than 84% of 4.16 kV within one second following the start of any large 4 kV motor (Refs. 4.1.3-4.1.5). For LOOP without LOCA, the results of each calculation show that voltage recovers to more than 84% of 4.16 kV within one second following the start of the RHR service water pump motor (Refs. 4.1.3-4.1.5). Therefore, the 4.16 kV ESS bus voltage will recover above 3494 V (84% of 4.16 kV) within one second following the largest expected EOG voltage transient. This EOG recovery voltage value is greater than the maximum dropout voltage of the recommended LOV relay setpoint as shown below.

'Vrecovery = 3494V Vmax.dropout = [(OVtap

  • 95%) + 2.25V] X 35 = 3171 V The initial EOG transient voltage dip due to large motor starts, before one second has elapsed, will be less than 3494V. This dip is acceptable since it will be of a short duration (less than one second) and below the time-voltage characteristic curve of the LOV relay (Ref. 4.4.2) with the relay set at 95% of 93V.

The Unit 1, Unit 2, and 1/2 diesel loading calculations have been superseded by ETAP calculation QDC-6700-E-1503 (Ref. 4.1.2); however, the ETAP calculation does not maintain the transient voltage dip analysis. Per Engineering Judgment 3.3.1, the transient voltage dip analysis from the diesel loading calculations can be used for this evaluation. Furthermore, there is margin between the expected EOG voltage transient and the dropout voltage of the LOV relay.

Calculation QDC-6700-E-1503, Rev. 008 (Ref. 4.1.2) evaluates the voltage drop on the 4.16 kV ESS buses during LOCA block starts to ensure that the voltage at those buses recovers before the degraded voltage relays separate the buses from the degraded grid condition. The ETAP output reports from Calculation QDC-6700-E-1503, for the block start analyses, were reviewed. These reports include the ~OCA block start analyses for Unit 1 and Unit 2 with the reserve auxiliary transformer load tap changers in both automatic and manual mode. The voltage drop on the 4.16 kV ESS buses during the evaluated LOCA block starts remained above the maximum dropout voltage of the LOV relays.

8.6 Coordination with Protective Devices The phase protective relays feeding the motors on the 4.16 kV ESS buses and feeding the 480 V ESS transformers are GE IAC-51 and GE IAC-66 relays (Refs.

4.6.3-4.6.6). Based on the instantaneous time-current curves for these relays, the operating time is less than 0.02 seconds for any pickup setting (Refs. 4.4.5-4.4.6).

I Analysis No. QDC*6700*E*2173 Revision 000 PAGE 18of18 I The ground protective relays feeding the motors on the 4.16 kV ESS buses and feeding the 480 VESS transformers are GE PJC-11 relays (Refs. 4.6.3-4.6.6).

Based on the instantaneous time-current curve for this relay, the operating time is less than 0.05 seconds for any pickup setting (Refs. 4.4. 7). The LOV relay dropout time is greater than 1 second for all operating voltages. Therefore, the instantaneous units for the protective relays feeding the motors on the 4.16 kV ESS buses and feeding the 480 V ESS transformers will clear faults faster than the LOV relays will dropout on low voltage.

8.7 Analytical Limits Consistent with the existing LOV relay settings, the upper and lower analytical limits for the LOV relay are selected as +/-5% of the recommended LOV relay nominal setpoint as shown below:

13-1, 14-1, 23-1, and 24-1) fixed at a voltage of 2850 V. The worst case expected EOG transient voltage dip was shown to recover above 3494 V in one second in Section 8.5. These voltage values are bounded by the selected lower and upper analytical limits for the LOV relay.

9.0 CONCLUSION

S 9.1 This calculation evaluated the LOV relay setpoint to ensure that the safety-related motors that may be running during normal conditions will continue to operate during the maximum 332.3 second degraded voltage time delay without stalling or tripping due to thermal overload relay operation. A setpoint of 88.35 V (93V OV tap, 95% UV setting) with +/-5% tolerance for the LOV relays was found to be high enough to prevent the stalling and tripping of safety-related motors that may be running during normal conditions and low enough to prevent spurious operation due to expected voltage transients. This satisfies the acceptance criteria. New upper and lower analytical limits for the LOV relay were calculated as 3246 V and 2938 V, respectively.

Also, the worst voltage recovery after one second following the start of large 4kv motor (Core Spray Pump motor during LOOP / LOCA) is above 85% of DG terminal rated voltage for LOOP I LOCA and more than 84% of Bus rated voltage when the Service Water Pump Motor is started during LOOP without LOCA. This voltage recovery Is above the minimum voltage recovery of 80% per the DG specification K-2183 requirement.

Also, the analysis in Table 2 and e shows, and the detailed explanation under the Calculation and Results section shows that while some of the control circuits may dropout during the lowest portion of the voltage dip, no adverse effects are Identified and no protective devices are expected to oper~te. The calculation also shows that momentary voltage dip will not cause the travel time of any MOV to Increase any longer than allowable. *

XI. CONCLUSION

  • ~

1 The results of the calculation show that the maximum continuous running load under the maximum ~

~ loading scenario is below the nameplate rating of the DG. Also, the worst voltage recovery after ~

  • one second following the start of large 4kv motor (Core Spray Pump motor during LOOP I LOCA) is ~

above 85% of DG terminal rated voltage for LOOP I LOCA and more than 84% of Bus rated voltage l when the Service Water Pump Motor is started during LOOP without LOCA. This voltage recovery i is above the minimum voltage recovery of 80% per the DG specification K-2183 requirement. i

,~

Also, the analysis in Table 2 and 6 shows, and the detailed explanation under the Calculation and  !

Results section show that while some of the control circuits may dropout during the lowest portion o~ '

the voltage dip, no adverse effects are identified and no protective devices are expected to operate. ~

The calculation also shows that momentary voltage dip will not cause the travel time of any MOV to ~

increase any longer than allowable. ~

~

The calculation also show that the starting time of automatically started 4-kv RHR Pump motors 2C ~

& 20 are less than 4 Seconds and the starting time for Core Spray Pump motor is under 5 seconds. ~

Starting time of all these pump motors are within the time setting requrements, even with a +/-10% to) erance (Ref. 68) in the time setting interval.  !

CONCLUSION The results of the calculation show that the maximum continuous running load under the maximum loading scenario is above the nameplate rating of the DG, but is less than the 2000 hour0.0231 days <br />0.556 hours <br />0.00331 weeks <br />7.61e-4 months <br /> per year rating of the Diesel Generator. Also, the worst voltage recovery after one second following the start of large 4kv motor (Core Spray Pump motor during LOOP I LOCA) is above 88% (for Unit 1 Division 1) and 84% (for Unit 2 Division 1) of DG terminal rated voltage for LOOP I LOCA and more than 84% of Bus rated voltage when the Service Water Pump Motor is started during LOOP without LOCA. This voltage recovery is above the minimum voltage recovery of 80% per the DG specification K-2183 requirement.

Also, the analysis in Table 2 and 6 shows, and the detailed explanation under the Calculation and Results section show that while some of the control circuits may dropout during the lowest portion of the voltage dip, no adverse effects are identified and no protective devices are expected to operate. The calculation also shows that momentary

- voltage dip will not cause the travel time of any MOV to increase any longer than allowable.

The calculation also shows that the starting time of automatically started 4-kv motors (i.e.

RHRs and Core Spray) are under 4 seconds which are within the time setting requrements. This includes allowing for tolerance of +/-10% (+/-0.5 seconds) in the timer setting interval.
