4 NOTES FOR TABLES 8.3-2a and 8.3-2b (1) The time indicated in this column is calculated from the instant LOCA and/or LOOP signals given to emergency diesel generators.
Maximum time for standby diesel generators to start and attain rated speed and frequency, including diesel generator air circuit breaker (ACB) closure, is 10 sec.
(2) Nameplate horsepower and brake horsepower are supplied by vendors for their furnished equipment. The required kilowatts for each load are calculated by using brake horsepower and the efficiency data supplied by vendors of the respective equipment.
(3) This load starts and/or stops automatically with satisfactory complete actuation or energization of its associated pump, valves, pressure or temperature switches interlocks, or energization of the required buses from the standby power sources.
(4) Motor operators of the MOVs stop automatically when the valve action is completed. All MOV loads complete their intended operation and are deenergized within 10 min of diesel generator ACB closing. MOV actuation after 10 min is assumed to occur on an individual and random basis, and the resultant loads are assumed to be inconsequential.
8A 8 9 (5) Started and/or stopped manually by operator. The SCT fans will be started one hour into a LOP-LOCA.
8 8A 9 3 3 (6) 1LAC-XLC9 has two sources of power from which it may select. This is not tripped on LOCA and is normally connected to diesel generator 1EGS*EG1B. On diesel generator 1EGS*EG1B failure, 1LAC-XLC9 can be manually connected to diesel generator 1EGS*EG1A after the LPCS pump is turned off.
(7) 1C41*C001A and B may be energized at the discretion of the plant operator.
(8) The attached load profile is a representative loading considering a single failure during LOCA and loss of offsite power. At 2 hr, operators' manual actions are shown to trip and start loads which must not exceed the DG allowable loading limits.
(9) 1HVY*FN1A is supplied from diesel generator 1EGS*EG1A. 1HVY*FN1C and 1SWP*P2C are supplied from 1E22*S001G1C independently.
The operator shall shut off either 1HVY-FN1A or 1HVY*FN1C at his discretion if both fans operate simultaneously.
See notes and Load Profile (Fig. 8.3-14a and b, and 15) for effective loads.
Revision 23 5 of 5 (10) Times and load values shown are for information only. Actual setpoints are shown on the setpoint calculations.
(11) See Table 8.3-3 for loading of Division III ESF buses.
(12) Indicated kW demand is based on actual heat release loads of the equipment.
3 (13) Chiller 1HVK*CHL1B or D and its lube oil pump are given load sequencing permissive at 160 sec, but due to chillers internal program logic, it would start at 211 sec. Operation of chiller 1HVK*CHL1A or C will be in the following manner.
- a.
If 1HVK*P1B or D fails to start at time zero (10 sec), chiller 1HVK*CHL1A or C and its associated lube oil pump shall start automatically after 211 sec.
- b.
If there is low chilled water flow (O153 GPM) thru chiller 1HVK*CHL1B or D at any time during diesel loading, chiller 1HVK*CHL1A or C start will be initiated after 30 sec. If diesel sequence timer has already timed out (150 sec.), chiller 1HVK*CHL1A or C will start after an additional 51 sec. time delay.
- c.
If the normal chilled water flow thru chiller 1HVK*CHL1B or D is established, i.e. 1HVK*CHL1B or D started operating satisfactorily, then 1HVK*CHL1A or C and its associated pumps, fans, and a/c units will not start.
(14) The time indicated in this column includes 30 sec time delay after signal initiation of low chilled water flow thru chiller 1HVK*CHL1B or D.
(15) The time indicated in this column includes 20 sec time for valve opening.
(16) The time indicated in this column includes 160 sec for chiller initiation signal.
(17) With circuit breaker closed, this load starts, stops and/or modulates automatically to maintain the control room temperature at set point.
15 11 (18) ENB-INV01A (01A1) and ENB-INV01B (01B1) are conservatively assumed operating on the 125 Vdc supply rather than the 480 Vac source. Thus these loads are reflected in the ENB-CHRGR1A and CHGR1B loading.
(19) Loading on the chargers ENB-CHGR1A and ENB-CHGR1B assumed to maximum loading of 47.5KVA for the first 10 minutes, after which the loading is assumed to drop to 32.4KVA.
11 3 12 (20) A margin is added to each step to allow for minor variations in fan BHP due to pitch settings to minimize USAR updates.
12 (21) ENB-INV01A (01A1) and ENB-INV01B (01B1) are divisionally redundant Vital Bus inverters. Only one of the two inverters will be in service for a division at one time.
15 (22) These loads have divisionally redundant loads supplied by EGS-EG1B.

Revision 10 6 of 7 April 1998 (1) Selected non-Class 1E loads, as shown on the above list, may be connected to the Class 1E ac system to ensure a supply of power to them during a loss of offsite power. These loads are kept operating during a loss of offsite power to preclude potential equipment damage and to provide additional operational flexibility, but are tripped on LOCA or LOOP and must be manually restarted.
(2) Non-Class 1E heaters mounted in Cat I motor-operated valves and temporarily connected to Class 1E panelboards during the construction phase are de-terminated at the panelboards after equipment release and prior to exceeding 5-percent power.
(3) The Class 1E voltage regulating transformer is connected to the nonsafety-related RPS bus panel-board via two series-connected independent Class 1E electrical protection assemblies (EPAs), and a circuit breaker and normally open contact in the RPS bus panelboard.
The RPS bus is normally energized from a non-Class 1E RPS motor generator set.
Upon loss of power from the MG set, the RPS bus can be manually transferred, via a switch in the main control room, to the alternate source upon closure of the normally open contact.
The two series-connected Class 1E EPAs, each acting independently, will open circuit during overvoltage, undervoltage, or underfrequency.
Hence, any adverse circuit condition on the nonsafety-related RPS bus will cause the Class 1E EPAs to open, thus protecting the voltage regulating transformer and its own upstream Class 1E source of power.
In addition, protection provided by the Class 1E voltage regulating transformer's internal circuit breaker and by the Class 1E MCC's feeder breaker ensure that an adverse condition on the load side of the transformer will not degrade the performance of the Class 1E source of power.
Fault current levels reflected back to the Class 1E MCCs have been evaluated to be only slightly higher than the load's full load current value.
(4) The lighting transformer, although not procured Class 1E, is identical in design and construction to RBS Class 1E small dry-type transformers.
It is connected to its Class 1E source of power via a series-connected circuit breaker and fuse in the motor control center.
Failure of one of these equivalently sized protection devices does not render the other inoperable, thus satisfying the single failure criterion.
- 10 (5) Power for the Polar Crane and the containment welding receptacle are connected to a Class 1E source which trip on a LOP/LOCA signal.
10*
(6) The only sources of power in the standby cooling tower are Class 1E. These loads are tripped on LOCA.
(7) Evaluation has demonstrated that open, short, or ground circuits in the slide wire transducer will have no adverse affect on the Class 1E portion of the circuit.
(8) Evaluation has demonstrated that open, short, or ground circuits of the limit switch will have no adverse affect on the Class 1E portion of the circuit. Limit switches are for indicating lights only.
(9) Motor heaters for 1SWP*P2A, 1SWP*P2B, 1SWP*P2C, and 1SWP*P2D are non-Class 1E components connected to a Class 1E source of power via Class 1E cables and Category I raceways.
Protection is provided by redundant Class 1E protection devices, such that in the event of a short circuit at the heater and a single failure of a protection device, the redundant device will clear the fault and protect the other Class 1E devices connected to the same Class 1E source of power.
- 6 (10)Coils for SOV's so marked are non-Class 1E components connected to a Class 1E of power via Class 1E cables and CAT I raceways.
Protection is provided by redundant Class 1E protection devices such that in the event of a short circuit at the SOV coil and a single failure of a protection device, the redundant device will clear the fault and protect other Class 1E devices connected to the same Class 1E power source.

(12)C11-TRR018-1 and -2 have been analyzed and/or tested to meet the separation requirements of Regulatory Guide 1.75/IEEE 384 per calculation G13.18.3.6*006.
(13)Containment personnel airlocks 1JRB*DRA1 and 1JRB*DRA2 are non-class 1E components which will be connected to a safety related power source should non-class 1E power fail. The class 1E double fusing circuit provided in the secondary of the control transformer is capable of clearing the fault and protecting the class 1E power source and other loads connected to it.
