PCN 561 NRC Questions and SCE Responses The minimum voltages above are based on the following Class 1 E 4.16 kV buses and switchyard voltages:
Voltage at Sicyr Bus E 4.16 kV voltage (r)
Reference
_ _ _b u s v l a e ( V Unit 2 Train A bus 214774 Sheets 5 & 8 of E4C-2A04 214.774 090, CCN #117 Unit 2 Train B bus 214.912 Sheets 14 & 18 of 2A06 4106 V E4C-090, CCN #117 Unit 3 Train A bus 215.234 Sheets 41 & 44 of 3A04 E4C-090, CCN #117 Unit 3 Train B bus 214.015 Sheet 50 & 54 of E4C-3A06 090, CCN #117 As shown in the Table above, the analysis using -215 kV in the switchyard shows adequate voltages for continuous operation.
- 2. Starting voltage All motors (4160 V & 460 V) are capable of starting at 75% of the rated voltage. But the motor terminal voltage dip during starting could be lower than 75% of the rated voltage. The acceptability of the motor terminal voltage dipping below 75% is based on NEMA MG1-12-44.2 (1991), which states, " The limiting values of voltage and frequency under which a motor will successfully start and accelerate to running speed depend on the margin between the speed-torque curve of the motor at rated voltage and frequency and the speed-torque curve of the load under starting conditions. Since the torque developed by the motor at any speed is approximately proportional to the square of the voltage and inversely proportional to the square of frequency, it is generally desirable to determine what voltage and frequency variations will actually occur at each installation, taking into account any voltage drop resulting from the starting current drawn by the motor."
Therefore, section 1.2.1 (Acceptance criteria) of calculation E4C-082 (System dynamic voltage during DBA) states "the motor terminal voltage during the starting and accelerating period should be adequate such that the corresponding motor torque is constantly more than the load required, allowing the motor to accelerate to its rated speed."
As shown in calculation E4C-082, ICCN C-51, Study Case l.B-A215 was done to calculate initial voltage, minimum voltage at motor terminals, and post accident voltage at motor terminals for Unit 3 train A at a switchyard voltage of 215.234 kV (sheet 30 of calculation E4C-082, ICCN C-51). The results show that all Class 1 E motors accelerate to their rated speed within the required acceleration time and the results are summarized in Table 2.1.2.2 of calculation E4C-082, ICCN C-51.

PCN 561 NRC Questions and SCE ResDonses NRC Question 2:
Provide a summary of the ongoing evaluation of voltages at the 208V/120V levels and address how these loads will have adequate terminal voltages during all conditions.
SCE Response:
- 1. Class 1 E 120 V AC power distribution panels Voltage ratio of the transformers for Class 1 E 120 V systems are 480 - 208/120 V.
However, the 208 V system is not used at SONGS. Voltages at Class 1 E 120 V AC power distribution panels and load terminals were evaluated to verify adequacy of the voltage for the application when voltages at Class 1 E 4.16 kV buses are 4106 V.
The lower analysis limit voltage of 4106 V was determined in calculation E4C-090, CCN 117 (AttachmentJ to PCN 561).
It was determined that 8 cables (between power distribution panels and loads) should be changed from 12 AWG to 8 AWG or 1/0 AWG to supply adequate voltage to loads. Design change packages for the cable changes have been issued.
- 2. 120 V AC control circuit of Class 1 E 480 V MCCs Voltages at starter coil terminals of Class 1 E 480 V MCCs were evaluated to verify adequacy of the voltage for motor control when voltages at Class 1E 4.16 kV buses are 4106 V. The results of the evaluation show that voltages at some 120 V AC control circuits are not enough for the application due to the long field cable.
Seven starters for Units 2 & 3 require the following modification:
Interposing relay installation in MCC control schemes for 1 starter Control Power Transformer (CPT) replacements with lower impedance and higher power rating (100VA to 300VA). Six CPTs are being replaced.
Thirty starters for Units 2 & 3 require the following tests to determine if any design modification is required:
MCC 480/120V Control Power Transformers (CPT) performance validation tests The nominal voltage ratio of the CPT is 480/120 V, but actual secondary voltage with a primary voltage of 480 V is a range of 122.4 V to 126 V. For conservatism CPT ratio of 480/122.4 = 3.922 was used for the voltage evaluation. Therefore, if the tested CPT ratio is low enough to provide required voltage to the starter terminal, no design modification is required.

PCN 561 NRC Questions and SCE Responses NRC Question 7:
State that there are no random loads that will come on at the 480VAC and 208VW120V levels during load sequencing or if there are some random loads, explain how they are accounted for in the calc.
SCE Response:
A complete review of the unit 3 train A loads (typical of both trains of both units) was conducted. It was concluded from a review that only a few small 480V loads listed below are random. All of the required 480V loads including HVAC loads are designed to start at the assigned sequence steps. Motor Control Center (MCC) loads that might be started or running have been treated as running or started in load group 1 for conservatism. In addition, margin for future load additions, approximately 25kVA for motor load has been treated as starting with load group 1 and approximately 25kVA of non-motor load is treated as running load. All of the Motor Operated Valves (MOVs) that could start during the load sequence are considered in closing or opening mode with inrush current (start mode) during the entire load sequence cycle.
A few small loads, Intake structure fans A370 & 373 (5HP), DG fuel transfer pumps P093 & P096 (1 HP), and Battery room emergency exhaust fan A173(5HP) that are treated as running in the analysis are random and are not expected to start during sequencing. The margin added by considering the additional loading listed above is much more than additional loading imposed if any of the random loads starts during the load sequencing.
SONGS has 208/120V transformers installed in the MCCs. All the loads are 120V.
Conservative loading is used in the calculation that envelops any momentary inrush current of permanently connected and random120V loads.

PCN 561 NRC Questions and SCE Responses NRC Question 8:
Explain the 4.11 second timer setpoint in Technical Specification (TS) 3.3.7 and the basis for the 4.11 seconds in Calculation E4C-082. Also, describe how one timer opens the voltage check window with a SIAS present and another timer closes the voltage check window.
SCE Response:
The time delays for the Degraded Grid Voltage with SIAS Signal (DGVSS) were selected to meet the following design requirements:
- 1. The allowable time delay, including margin, shall not exceed the maximum time delay that is assumed in the FSAR accident analyses;
- 2. The time delay shall minimize the effect of short duration disturbances from reducing the availability of the offsite power source(s); and
- 3. The allowable time duration of a degraded voltage condition at all distribution system levels shall not result in failure of safety systems or components.
The time delay settings of the DGVSS detection timing relays (162S-1, 162S-2, 162S-3, 162S-4, 162T-1, 162T-2, 162T-3, and 162T-4) are selected to comply with the design objectives with due consideration to the tolerances associated with these timers, Emergency Safety Feature (ESF) load sequencing timing relays, and the response time of the degraded voltage relays (127D-1, 127D-2, 127D-3, and 127D-4).
- Timing relays 162S-1, 162S-2,162S-3, 162S-4 These timers are used to "open" the DGVSS window. The DGVSS window opening time has been analyzed to be adequate time for the grid voltage to recover from a short term voltage transient due to system disturbance or SONGS unit trip. ESF load group 2 starts at 5 seconds after initiation of an SIAS. ESF load sequencing uses Agastat relays with a tolerance of +/- 10% (0.5 seconds for the second load group). Therefore, the 162S timing should be less than 4.5 seconds after initiation of an SIAS so that the DGVSS window opens before load group 2 sequencing begins. With a setting of 4.3 sec, the DGVSS window could open any time between 4.11 seconds and 4.49 seconds after initiation of an SIAS.
- Timing relays 162T-1, 162T-2, 162T-3, 162T-4 These timers are used to "close" the DGVSS window. The timers must be set to ensure that 1) load shedding and transfer of the bus to the EDGs occurs 10 of 19
PCN 561 NRC Questions and SCE Responses within the time allowed in the safety analyses, and 2) the voltage dip caused by the starting of the ESF load group 2 does not generate a spurious DGVSS.
Therefore, a time delay setting of 1.25 +/- 0.40 sec. is chosen. With this time delay setting the earliest the DGVSS window could close is 4.96 seconds after initiation of an SIAS (4.3 sec - 0.19 sec + 1.25 sec - 0.40 sec = 4.96 sec). The latest the DGVSS window could close is 6.14 seconds after initiation of an SIAS (4.3 sec + 0.19 sec + 1.25 sec + 0.40 sec = 6.14 sec). The DGVSS window will enable detection of the degraded voltage in the first ESF load group sequence and will not be affected by the subsequent ESF load starting transients.
The DGVSS trips the 4.16 kV Class 1 E source breakers. Because the latest a DGVSS bus trip may be initiated is 6.14 seconds after initiation of an SIAS, all ESF loads were analyzed for operation with a complete loss of voltage condition for up to 6.14 seconds and found acceptable.
Following initiation of a DGVSS, there is an additional time delay of 2.0 +/- 0.20 sec.
provided for load shedding. Following the 2 second time delay, the EDG breaker will close provided the EDG has attained normal voltage and speed. The EDG breaker will close within 10 seconds after initiation of an SIAS, which is the safety analysis time limit for EDG breaker closure.

- 2. Degraded voltage relay setting a) Maximum pickup (PU) setting of degraded voltage protection relay In order to ensure that 4.16 kV bus remains connected to the normal preferred offsite power source when the switchyard voltage is 218 kV and above, the following conditions should be met:
- The maximum reset voltage of the degraded voltage protection relay should be less than the voltage corresponding to the minimum switchyard voltage of 218 kV.
The voltage at the 4.16 kV level corresponding to the minimum switchyard voltage of 218 kV is the upper analysis limit voltage for the maximum reset voltage of the degraded voltage protection relay.
Calculation E4C-090, ICCN C-134 (Attachment K to PCN 561), determines the upper analysis limit voltage (4161 V).
- The 4.16 kV bus voltage at 4.11 seconds during load sequencing (refer to question 8 for an explanation of the 4.11 second time delay) should be greater than the maximum reset voltage of the degraded voltage protection relay when the switchyard voltage is 218 kV.
Calculation E4C-082, ICCN C-51 (Attachment I to PCN 561), verifies that 4.16 kV bus voltage at 4.11 seconds during load sequencing is greater than the upper analysis limit voltage (4161 V) for conservatism.

PCN 561 NRC Questions and SCE ResDonses b) Minimum dropout (DO) setting of degraded voltage protection relay Operation of the Class 1 E system with the voltage corresponding to the minimum dropout voltage of the degraded voltage protection relay must be adequate to ensure operability of plant equipment. Therefore, the minimum dropout voltage of the proposed degraded voltage protection relay must be greater than the lower analysis limit voltage.
Calculation E4C-090, CCN 117 (Attachment J to PCN 561), determines the lower analysis limit voltage (4106 V) and verifies that the lower analysis limit voltage is adequate for continuous operation of 4.16 kV & 480 V electrical equipment.
120 V power distribution systems and 120 V control circuit of Class 1 E 480 V MCCs were evaluated to determine that 4106 V at the Class I E 4.16 kV buses is adequate for Class 1 E 120 V circuits. It was concluded that the Class 1 E 4.16 kV buses with 4106 V does not provide adequate voltage to some 120 V power circuits and 120 V control circuit of 480 V MCC. As indicated in PCN 561, design modifications and testing are being done to improve voltages at 120V power distribution systems and Class 1 E 120 V control circuit of Class 1 E 480 V MCCs.
Calculation E4C-082, ICCN C-51 (Attachment I to PCN 561), verifies that with a switchyard voltage of 215.234 kV (for Unit 3 Train A) corresponding to the lower analysis limit voltage of 4106 V, all Class 1 E motors accelerate to their rated speed within the required acceleration.
c) Nominal PU & DO setting and Allowable Value of the degraded voltage protection relay The nominal PU and dropout DO of the degraded voltage protection relays were determined based on the upper analysis limit voltage and low analysis limit voltage, Total Loop Uncertainty (TLU), and design margin. See calculation E4C-130, ICCN C-6 (Attachment G to PCN 561) for detailed TLU and the nominal PU
& DO calculation.
The minimum allowable DO setting and maximum allowable PU setting were determined based on the nominal PU & DO settings and allowable value tolerance (AVT). See calculation E4C-1 30, ICCN C-6 (Attachment G to PCN 561) for detailed AVT calculation.

PCN 561 NRC Questions and SCE Responses NRC Question 12:
Because it takes approximately 6.6 seconds (i.e., 4.44 seconds delay plus the 2.17 seconds relay time) for the degraded grid relays to disconnect from the offsite power source when the SIAS signal is present, discuss what happens to those loads that are already sequenced on the safety buses assuming concurrent SIAS and degraded grid conditions. In addition, discuss the operation of the loads if SIAS occurs first in the above scenario and if there may be any problem in re-starting those loads on the DG.
SCE Response:
The response to Question 8 and the DGVSS/SDVS Logic Diagram (Attachment 1) explain that the time delay 162S for DGVSS window opening time delay is started by SIAS and independent of time delay of the degraded grid relay. The Window opens if 162S relay & associated 127D have operated. The window is closed when time delay 1 62T operates. Thus the DGVSS window opens between 4.11 and 4.49 seconds (4.3
+/- 0.19 sec) and closes between 4.96 and 6.14 sec from initiation of SIAS. All motor loads that were running or started in load group 1 will be tripped if the DGVSS is initiated. Following initiation of a DGVSS, there is an additional time delay of 2.0 i 0.20 sec. provided for breaker tripping and decaying of voltage at the loads prior to re-energizing. Following the 2 second time delay, the EDG breaker will close provided the bus voltage has decayed to 25% (detected by 127R relays) and the EDG has attained normal voltage and speed. Then the loads of load group 1 will restart and all other loads will start in proper sequence.
The motors are designed for two starts in succession with the motor at ambient temperature or one restart from running temperature condition per parts 12 and 20 of NEMA MG-1. There will be no degradation such that would prevent the restarting of these pumps. Therefore, there is no problem to restart these motors on the EDG.

PCN 561 NRC Questions and SCE Responses NRC Question 13:
It was stated in the meeting that on a sustained degraded grid condition, the SDVS will separate safety buses from the offsite power system if the degraded grid conditions are not improved within 130 seconds. Discuss if the plant is tripped under these conditions and indicate, if the plant is tripped, what signal trips the reactor in this scenario. If not, what actions are taken to prevent sequencing of safe shutdown loads on the safety bus when supplied by DG.
SCE Response:
Under a sustained degraded grid condition, the SDVS will separate the safety buses from the switchyard. There is no signal to automatically trip the plant under this condition. After separation of the safety buses following either a degraded grid condition or a loss of offsite power condition, the 4160 Volt buses are stripped of all motor loads and then connected to the diesel generators. If there is no accident, there is no automatic sequencing of loads onto the 4160 Volt or 480V buses. The safe shutdown loads are permanently connected to the 4160 Volt and 480 volt buses with the exception of the Component Cooling, Salt Water Cooling, and Shutdown Cooling (if required) pumps which the operators will manually reconnect onto the buses. In addition, Auxiliary Feed Water Pumps will auto connect if EFAS is present.
In the event of a degraded grid condition, the effects on specific plant loads may cause the operator to manually trip the plant. The last paragraph of SONGS UFSAR section 8.3.1.1.4.6 states 'Following diesel start and connection to the Class 1E bus, the required safety-related loads are connected to the bus at programmed time interval as shown in table 8.3-1".
The UFSAR will be revised to clarify that this sentence applies only if an auto actuation signal is present.

JR 1.2 ACCEPTANCE CRITERIA (for reference only) 1.2.1. All ESF motors that are required-to mitigate the consequences of a DBA should accelerate to their rated operating speeds within the required response time when supplied from tMe preferred power supplies under credible worst case (emergency) loading conditions. These motors loads include all ESF motors that are started via automatic sequence and some manually connected loads which are credited in the safety analysis.-
Tbe motor terminal voltage duiring the starting and accelerating period should be adequate such that the corresponding motor torque is constantly more than the load requires, allowing the mnotor to accelerate to its rated speed. Note that the torque developed by the motor at any speed is directly proportional to the square of the voltage and inversely proportional to the frequency. -

2.2 CONCLUSION
S:
The results of tbe this analysis show that all ESF motors accelerated to their rated speeds and meet the required acceleatioi time (Table 2.1.23.]). Successful acceleration to their rated speeds indicate that the calculated motor terminal voltages are adequate to maintain the corresponding mnotors to accelerate to their rated speeds. The motor starting times at the 3A04 bus voltage of 4106 V are longer than th& motor starting time. at rated voltage.
3.0 ASSUMPTIONS
See the base calculation for overall assumptions. No additional assumptions are introduced in this ICCN.

4.0 DESIGN DATAE
.4.14 PercalculationsE4C-130, degraded bus voltage relays 127D-1, 127D-2, 127D-3, and 127D-4 analysis limit is 4106 V.

MEMfODOLOGY:
5.12 e.1 CASE IS-A-OR -This case considers a Unit 3 ESF bus alignment for Train A with ESF bus connected to the X-winding of its dedicated Reserve Auxiliaiy Transformer. A lumped load of 20 MVA is considered in the Y-winding per Section 3.1 of the base calculation. A Design Basis Accident is postulated for Unit 3. This case is established to perform dynamic simulation daring the out-of-sequence starting of ESF loads due to a possible overlapping operation of the Agastat relay timer.The most limiting overlap cases were chosen on the basis of maximum loading at the buses. The maximum loading at the buses due to the possible overlapping operation of tie Agastat relay timer would occur when operating timr tolerance of the Agastat relay is +/- 2.5 seconds.

This case was established to verify voltages at buses & motors, and the capability of motors of Unit 3 to start, based on a predetermined sequence. All ESF loads are operating that art required to mitigate the consequences of a Design Basis Accident (DBA) when connected to the nonnal preferred power source. Loading sequence is based on Table 1 0.1, Case I.B-A-OR The switchyard voltage used in this analysis is 215.234 kV, which corresponds to the design limit voltage of 4106 V atbus 3A04 (referenceE4C-090, R3 CCN-117).

3.0 ASSUMPTIONS 3.1 In Mode I (Cases I and 11). the total load in on each Reserve Auxiliary Transformer (RAT) secondary Y-wiring, which supplies the Non-ESF buses 2A03, 2A07, 2A08, 2A09, 3A03, 3A07, 3A08, and 3A09 are assumed equal to the full MVA (OA) rating of the winding of RAT secondary Y-winding at power factor of 85%, i.e., 20MVA at 0.85 power factor (17+J1 0.536)MVA. This is acceptable since 20DMVA Is a conservative estimate of the actual loading and any change in the loading of the Y-winding does not significantly affect the voltage of the X-winding in a three winding transformer. Accordingly, any change in the loading of non-ESF buses connected to the Y-rwinding of these RAT has negligible effect on the voltage of ESF busses connected to the X-winding of these transformers.
3:2 Assumptions and methods used In the development of equipment parameters for the Unit 2 & 3 data calculation E4C-086 (Ref. 6.3) are applicable to this calculation.
3.3 Any ESF load which could start coincident with the initiation of an accident signal and is not prevented from being started by an automatic control, operating Instructions, or administrative limitations, is assumed to start. Likewise, any ESF load which could be running prior to the initiation of an accident signal and which Is not automatically tripped by the signal is assumed to continue running.
3.4 For Case 111
& 1U2EDG, maintained voltage at the diesel generator Is assumed to be at (4.38 KV). Per reference 6.61, the motor operated potentiometer (MOP) Indicates a voltage setpolnt for the EDG regulator of 4460a80 volts, or a minimum of 4380 volts. With the majority of EDG loads being Induction motors (constant KVA devices), assuming a regulated voltage of 4380 volts for this analysis is conservative since system losses (based on current flow) will be higher.
See sectIon 4.10 of calculation E4C-090 (Ref. 6.2).
3.5 The analysis consider a design basis accident that would result in the Initiation of a SIAS or SIAS with concurrent EFAS and LOVS. One of the HPSI Is on test and remain connected to the 4-kV bus upon initiation of theses accident signals. Accordingly, two HPSI Pumps are started during the initial load group sequencing operation.
3.6 The analysis considers a Safety Injection Actuation Signal (SIAS) concurrent with an Emergency Feedwater Actuation Signal (EFAS). In Cases Ill-A and IlIl-B a loss of Voltage Signal Voltage is also considered. The Auxiliary Feedwater Pumps are trip at t = 0 seconds on SIAS. After all the required ESF loads are sequenced (except the Auxiliary Building Emergency Chillers), the Auxiliary Feedwater Pumps re-start at t=30 seconds and the Auxiliary Building Emergency Chillers start at t = 35 seconds. This results In the worst case sequencing configuration for a dynamic voltage analysis.
.3.7 5KVA Lumped Static Load and 5 HP Lumped Motor Load are added to each ESF MCC to allow for future load growth.

CCW Subject AUXILARY SYSTEM VOLTAGE REGULATION Sheet 27 of REV ORGNATOR DATE IRE DATE REV ORIGINATOR DATE IRE DATE 3.o ASSUMPTIONS The assumptions described in this section are considered conservative for the purposes of this calculation. Some are an Integral part of the methodology used, while others are based on engineering judgment. A basis or a thought process for the assumption is provided where appropriate, or a reference to a source of further Information is Indicated.
3,1 Fpr the purpose of obtaining cable resistance values, cable conductors are assumed lo be at an operating temperature of 750 C for all study cases. Operating temperatures higher than 750 C may be experlonced for short cable runs associated with loads or tray sections located In high ambient temperature locations. However, when evaluating the entire cable run, a temperature of 750 C Is considered a conservative value.
- 32.
Intermittent loads such as cranes, hoists, utility power, and MOVs are not considered In the analysis. For example, large cranes and hoists wfll be operated for short periods and are most likely to occur during conditions of reduced system loading, such as during plant outages. MOVs are typtcally small loads, which operate for a relatively short duration.
Hence, these types of loads do not represent steady-state conditions for the auxiliary electrical system.
3.3 Voltage criteria specified In Section 1 are based on rated frequency. For the purposes of this calculation, It is assumed that steady-state system frequency Is 60Hz for all study cases.
Frequencies other than 50Hz are not addressed in this calculation, as these are transient conditions. For additlonal Information on frequency considerations at SONGS, see Reference 6.301, Sections 3.11.62 and 8.22.1.2.
3.4 Subsequent lo a Safety Injection Actuation Signal (SIAS), all non-Class 1 E loads that are supplied from a Class 1 E bus are automatically disconnected (References 6.301 and 6.302).
However, these loads are capable of being reconnected during the post-accident period (see Reference 6.304, Attachment 12). For the purposes of this calculation and Its applicable cases, these loads are assumed to be steady-state loads during the post-accident period.
This assumption ensures that the bus loading In the included analysis Is bounding for all possible post-acoident loading conditions. See also Section 5.3.1.
3.5 For the purposes of this calculation, non-Class 1 E MCCs are modeled as lumped motor and lumpeO static loads as described In Reference 6.102. The individual MCC motor feeders are assumed a voltage drop allowance of 3% (see Section 5.12). This Is In agreement with the methodology described in calculation E4C-120 (Reference 6.105) that Inludes voltage drop analyses fQr non-Class I E MCC loads.

iDATE1 3.6 In general, MOO bus loading is assumed as follows:
Minimum Voltaae Cases Non-Class 1 E MOOs are assumed loaded at 75% of connected toad untess otherwise noted The MCCs are represented as lumped loads based on the load tables In Section 8 of calculation E40-086 (Reference 6.102).
Class 1 E MCCs are assumed loaded at 75% of connected load for non-abdidant scenarios%
and 100% 6f connected emergency load for accident scenarios unlss otherwise noted. See also Section 5.3.1.
All MCC loading, unless otherwise noted, hIcludes motor (5 HP) and static (5 kVA) margin
- loads, Maxlmum Voltage Cases Non-Class I E MCCs are assumed loaded at 25% of connected load unless otherwise noted.
Class 1E MCCs are assumed (oaded at 25% of conndcted load unless otherwise noted.
Load margin values are not Included.
These general loading oonditions are judged conservative for this analysis, Se also Section 3.2.
37 Assumptions described In calculation E40-086 (Reference 6.102) are applicable to this calculation unless othenvise noted.
3.8 For motor starting cases (A8, A9, A10, AlOa, Al1t, BA8, 3A9, 3AIO, SA10a and 3A11), the starting motor is assurned to be a constant Impedance (static) load. This load derives Its running current and running power factor from the respective motor's starljng current and starting power factor. See Section 5.10.

3.9 In general, conservative assumptions are applied to the bus loading alignments described In Section 5.3. Under normal plant conditions, some loads are cycled, while others may be chosen to run at the discretion of the plant operators. Loading scenarios In this calculation were selected In an effort to envelope a wide range of operating needs, but cannot Include all possible plant alignments. Section 5.3 describes specific loading conditions that are assumed for the plant operating In Modes 1 -4 and In Modes 5 & 6.
The following are also assumed for the Class I E buses:
a)
For long term bus loading (cases AlSa, Ai3b, SAI 3a, SA1 3b only), no HPSI, LPSI or AFW Pump Is assumed operating in Modes 1 -4 (See Section 5.f and Reference 6.502).
b)
For short term bus loading, one AFW pump on each train Is assumed operating In Modes 1 -4. This loading envelopes a postulated HPSI, LPSI, or AFW pump operating on the bus.
c)
Salt Water Cooling Pumps are assumed operating one per train in all modes.
d)
Two COIW pumps are assumed operating on a single Class 1 E bus In Modes 1 -4 forcases AS, Ag, 3A8, and 3A9. For othercases, one CCW pump is essunfed operating on each train.
e)
For accident scenarios, all three HiPSI pumps are assumed to be operating.
3.10 For the Class I E battery chargers 2(3)BOO1 through 2(3)B004, It is assumed that the chargers are not operating at full load (at current limit level. Par battery testing maintenance orders (Reference 6.60B), the charger will typically deliver over 200 amperes of current for 3 hours3.472222e-5 days <br />8.333333e-4 hours <br />4.960317e-6 weeks <br />1.1415e-6 months <br /> or less on a post-service test recharge cycle. Hance, a fully loaded charger Is not considered as a long term steady-state load In this calculation. However, a conservative load of 200 amperes DC is assumed based on emergency loading. It Is further assumed that the battery charger has an efficiency valued of 0.85. SOD also SecUon 5.6.
3.11 Specific study cases are analyzed for Unit 2 only. For these cases, Unit 3 Is assumed similar due to its similar design features. See Tables 5-1 through 5-5 for details.
3.12 To obtain Initial acceptance criteria for 480V MCC maximum voltage study cases (Table 1-7),
it Is assumed that the maximum allowable bus voltage is equivalent to the maximum motor terminal voltage. This Is a conservative assumption, and neglects any voltage drop from the 480V bus to the motor. See Section 5.12.
3.13 For rnotor starting cases Al Oa, Al1, 3A1 Oa and 3A1 1, It is assumed that Reactor Coolant Pump 2(3)PO92 Is started. This replacement motor has a higher inrush current than the original motors. It Is chosen because it represents the limiting condition for starting any one.

3.14 For minimum voltage study cases where the main generator Is connected and its voltage is adjusted to 95% rated, the switchyard voltage is assumed to be 226kV (Section 4.1). For maximurn voltage study cases where the swltchyard voltage Is acdusted to 232kV with the main generator connected, the generator Is assumed to operate at its nominal reactive power output of 250MVAR (Reference 6.6O0).
3.15 For cases related to the DGVS setpoint, once a switchyard voltage Is established which causes any one of the Class i E buses being analyzed to be at the specified DGVS setpolnt (Section 4.3), that switchyard voltage Is considered valid for all Class lE 4.16kV buses that are Included in that analysis. Analyses are not included for the redundant train with its bus at the respective setpoint This is acceptable since there is only a small voltage difference between any of the Class I E 4.16kVbuses for a given swHchyard voltage. See also Section 5A.
3.16 For all non-motor loads, acceptable voltage variation is ass uned 1o be +/- 10% of rated voltage. This Is judged to be conservative for non-motor loads, and Is consistent with the allowedvariaton for motor loads based on published standards. Ratedvoltage forall non-motor loads Is assumed to be 480V. See also Sections 1.3.1.5 and 5.1 12.
3.17 For certain cases, a Unit postulated to be in safe shutdown mode Is assigned to be operatng Its accident mitigating loads caused by a spurious accident signal. This conservative approach will be boundiig for all loading requirements for safe shutdown as required In the UFSAR. Sao Sectlon 4.6.
3.18 For the Class IE loadcentertransfonner long term loading study (cases AMa Al3b, 3AIa and SAJ 3b), It Is assumed that the plant rFe will terrnbate concurrent with its license In the year 2022. See Section 5.5.
