-Supplement No. '17 1

1 An additional m3asura of auxiliary power reliability for the plant will be 3

- achieved by providing for quick replacement of Start-Up Transformer No.1 by the Unit Auxiliary Transfomer in the event of failure of Start-Up Transformer No. 1. The changeover will be by means of reconnection of over-head swing leads and isophase bus links without a physical relocation of the

- transformers.

8.2.2.2 6900-Volt Auxiliary System Two 6900-volt buses will be provided for the operation of the four reactor coolant pumps. This wi].1 provide the necessary flexibility and reliability during normal plant operation,' start-up and shutdown. During normal operation, each bus.will be fed from the 6.9 kV winding of the Unit Auxiliary Transfomer.

During start-up and shutdown, the buses will be fed from the 6 9 kV secondary winding of the Start-Up Trancformer No.1 or of the Start-Up Transformer No. 2. l3 Normal transfer of the 6900-volt auxiliary system between the three sources will be initiated by the operator from the control room, while emergency trans-fer from the Auxiliary Transfomer to one of the Start-Up Transformers will be initiated automatically by protective relay action. Uomal bus transfers used on start-up or shutdown of a unit will be " live bus" transfers, i.e. the incoming source feeder circuit-breaker will be closed onto the energized bus section and its interlocks will trip the outgoing source feeder circuit breaker which will result in transfers without power interruption. After closing of 6 the circuit breaker of the incoming transformer, the supply breaker of the other transformer that was connected to the bus before the manual transfer was initiated will be automatically tripped when the operator releases the control switch handle of the incoming breaker. Paralleling sources which are out of phase will be prevented by the use of synchronism check relays.

Emergency bus transfers which will be used on the loss of normal unit sources

. will be rapid bus transfers, i.e., the normal source feeder circuit breaker

! will be tripped-and simultaneous 3y the emergency standby circuit breaker will close the incoming power source which will result in a transfer within a maximum of four cycles. The selection of one of the two start-up transformers 3 for emergency standby duty will be by means of a duty selector switch in the control room. The duty selector switch detemines which start-up transformer 6 transfers first on loss of normal unit source. When one of the start-up transfomers is in service, the other start-up transformer will autcmatically be .available for rapid bus transfer emergency standby duty.

All bus feeder circuit breaker control switches, bus synchronizing switches, 6 and emergency standby duty selector switches for 6900-volt, 4160-volt, and 480-volt buses will be located in the control room.

- 8.2.2 3 4160-Volt Auxiliary System Four 4160-volt buses will be'provided. Two of the brMn t rovide power to 3 non safeguards k kV auxiliary motors, feeders to 4 6 dt con safeguards

- double-ended load ' centers and feeders to 4160-v9 M 'neered Safeguards Buses..

.Nomally these buses will be fed from a 4160-vett waiias of the Unit Auxiliary Transfomer. During start-up and shut-down, tha buses will be fed from 4160-volt winding of the Start-Up Transformer No.l'or Start-Up Transformer No.2. Normal .l3 h and emergency bus transfers.of the'4160-volt auxiliary system between the three sources will be 'similar to the 6900-volt system bus transfers described in

- 8.2.2.2'above.

Upon loss of normal and- standby power sources the two 4160-volt Engineered Safeguards;Euses will be energized from their respective diesel generator.

Eus load shedding,5 bus transfer to the' diesel generator, and pickup of critical loads will be automatic.

, 6.2.2.4 480-Volt Auxiliary System The.480-volt system is divided into three load centers with two bus sections each. Power for each bus section will be supplied from a separate load

-center transformer. The transformers will be fed from the 4160-volt system and arranged so that each transformer of a double-ended load center unit is fed from a different 4160-volt bus. The capacities of the load center trans-formers and the 480-volt bus tie breakers are sufficient to permit plant operation with one transformer out of service. A spare lead center trans- 3 fomer, interchangeable with any of the six load center transformers in service, will be provided. The system will be arranged so that multiple -

pieces of equipment.with a co==on function are fed from opposite buses; thus, the loss of any 480-volt bus or the failure of any single component of the 4160-volt or 480-volt systems would not deprive the plant of all equipment _ associated with that particular function. -

A 480-volt preferred emergency a bus, capable of being supplied from either' '

bus section of the 460-volt engineered safe 5uards load center by automatic changeover- of the supply breakers, will be arran5ed to supply such leads as emergency' lighting, standby battery charger and emergency bearing all pump.

, Various 4EO-volt motor control centers will be located throughcat the station to supply power to the equipment within the related area.

8.2.2.6 120/208 Volt Instrument Ac System A120/208 V ac switchboard with two bus sections will be'frovided for normal station service and ncn-essential reactor auxiliary control instrumentation and instrument cooling fan power supply.

These buses have alternate supplies from two engineered safeguard motor control centers via one of two 480-120/208 V step-down transformers each rated to carry the full load of both bus sections. Upon the loss of one source or. transformer, autmatic transfer will maintain the supply front alternate source via the second transformer. Both engineered safeguard motor-control centers supplying the 480-120/208 V transformers are capable of being supplied from either df the two diesel generators in the case of plant emergency.

~8.2.2.7 120 Volt Vital Ac System A 120 volt uninterruptable ac power system will be provided to supply the reactor protection and engineered safeguards control channels. This power 13 supply system will consist of four inverters' (480 volt ac and 125 volt de input (17 with 120 volt ac output) and four distribution panels which will provide on inde-pendent power source to each protective channel.

The essential equipment such as nuclear instruments, nuclear auxiliary instruments, integrated control devices, and control rod drive position indicating lights will be distributed and will be connected.to these four panels. The computer data-logger which is non-essential for the reactor protection system will be connected to a* separate inverter unit. l17 Inverter trouble and bus low yolta6e will be annunciated in the control room.

8.2.2.5 Evaluation of the Physical Layout of Electrical Distribution System Equipment The physical locations of electrical distribution system equipnent will be such as to minimize vulnerability of vital circuits to physical damage as a result of accidents. The proposed locations are as follows:

(a) Unit Auxiliary Transformer and Start-Up Transformers will be located i out of doors with sufficient physical separation from each other or l2  !

separated by the fire walls. Lightning arresters will be used where  !

applicable for lightning protection. All transformers will be covered '

by automatic water spray systems to extinguish oil fires quickly and

~

prevent the spread of fire.

(b) The engineered safeguard 4160-volt switchgear and 480-volt load l17 centers will be located within Class 1 structure area so as to l3 minimize exposure to mechanin g, fire and water damage. This )

equipment will be properly coordinated electrically to permit I safe operation of the equipment under normal and short circuit conditions.

8.2 3 M ERGENCY POWER ~

Ene emergency power sources are designed to provide a' dependable supply of power for critical services in the unlikely event of simultaneous loss of normal and standby'p'ower.

. 8.2 3 1- Emergency Diesel Generators

/

The two Engineered Safe 6uards Buses, each supplying equipment essential to ,

the shutdown of the plant, are capable of being supplied from the Unit ~~

Auxiliary Transformer, or Start-Up Transformer No. 1 or Start-Up Transformer 3 Wo. '2, or frem either of the two emergency diese1 generators.

Two full capacity size diesel generator units will provide station emergency power and satisfy engineered safeguard loads for essential. auxiliaries. Each generatoi will be supplied with a high speed voltage regulator designed to -

return generator voltage to rated value within a minimum delay after staiting of the largest motor. The rating of each of the_ diesel generaters and the tie breakers of the Engineered Safeguards. buses is sufficient to carry the 3

. vital simultaneous load of both bus sectiens. If a' fault ' occurs on o'ne bus,

that bus will be isolated. Either bus can feed the power to the equipment ,

-necessary to' shut down the unit in a. safe condition.

Both diesel generators will be started automatically by under-voltage relays on Engineered' Safeguards buses #A3 or A4 or by a safety injection signal. , j 3_

In addition to starting the diesel generators the undervoltage relay on the m bus will isolate the bus frcm its normal supply source and trip all outgoing feeder breakers.

A voltage relay connected to the potential transformers at the diesel gener-ator terminals will detect generator rated voltage condition and provide a permissive interlock for the closing of the respective generator circuit breaker. Thus, if both diesel generators start, Engineered Safeguards buses 3

1. A3 and #A4 will be supplied separately from each of the two generators with the bus tie breakers open. No automatic closing of the tie breakers between the 4160-volt engineered safeguards buses will be provided. Manual closing

~

of these circuit breakers will also be prevented by an interlock when both emergency diesel generators are in service.

Manual closing of the breakers will be possible, only:

(a) if the 4160 volt engineered safeguard buses are being fed from the outside source and both emergency diesel generators are not in service. ,

(b) If on loss of offsite power only one emergency diesel generator starts or subsequent to both starting one fails in service.

As an additional measure of safety for preventing the two diesel generators from being tied together the control switches for the two bus tie breakers will have key locked handles.

The essential loads will be automat'ically energized in a predetermined sequence with time intervals sufficient to allow the starting inrush current to decay before proceeding with the starting of next motor. After each motor is given the signal to start the closing of the motor circuit breaker will be checked. If the circuit breaker should have failed to close an alarm window for the respective motor will be annunciated in the control room.

The diesel generator loads and the sequence of starting on emergency shut- 3 down condition are as shown in Table 8-1.

The loads required for operation in the MHA condition will be clearly below the capacity of one diesel generator, rated 2750 kw.

Spare capacity will be available for supplying vital loads not included for NHA operation, such as jockey fire pump, turbine emergency oil pump, turbine turning gear and additional motor operated valves.

One each of the primary make-up pump and service water pump motors can be l 17 fed from either Engineered Safeguards Bus. The circuit breakers for the double . fed motors are provided with a selector switch in order to assure proper bus selecting, and the closing circuits are interlocked to prevent both closing at the same time. Two reactor building cooler fan motors 17 are connected to each Engineered Safeguard Bus.

.Each generator will be equipped with means for starting periodically 3& #

to test for readiness and means for synchronizing the unit onto the bus p~

vithout interrupting the service. .

8.2 3 2 Station Battery ,

.The station batteries' will be sized to provide po,wer requirements for

-- vital auxiliaries, instrumentation, control equipment and minimum amount of emergency lighting for safe plant shutdown and to provide the controls to re-energize the plant auxiliary systems from the start-up source.

The batteries will'have sufficient capacity to carry emergency load for 6 +

a minimum period of two (2) hours without the battery chargers.

~

The ungrounded de system will have detectors to indicate when there is a ground existing on either system side. A ground on one side of the de .

system will not cause any equipment to malfunction.

Grounds will' be located by a logical isolation of individual circuits connected to the faulted system, while taking the necessary precautions ,

to maintain the integrity of the vital bus supplies.

8.3 TESTS AND INSEECTIONS

'A program of regular inspections and functional checks of equipment and protective devices comon to normal central station practice will iensure the operability of auxiliary. distribution system componerits. .

Emergency transfers to the various emergency power sources will be tested on a routine basis to prove the operational ability of these systems.

Periodic operating tests vill be perfomed on the diesel generators, the battery chargers, and the emergency lighting.
