4.9' AUXILIARY. ELECTRICAL SYSTEM Specification r:

< ' . A .- . Emergency Power Sources

1. Diesel Generator

a. The diesel generator shall be started and loaded once a month

. to demonstrate operational readiness. The test shall continue until the diesel engine and the generator are at equilibrium temperature.at full lead' output. During this' test, the diesel' starting air compressor will be checked for operation.and its ability to recharge air receivers.

-b. .During each refueling outage, the conditions.under which the diesel. generator is' required will be simulated.and a test conducted.to demonstrate that it will start and be ready.to accept load within 13-seconds.

c. During the monthly generator test, the diesel fuel oil transfer pumps shall be operated.

2. ' Gas Turbine Generator

a. The gas turbine generator shall be fast started and the' output

' breaker closed within 48 seconds once a month to demonstrate l operational readiness. The test shall continue until;the gas turbine and generator are at equilibrium temperature at full load output. ;Use of this unit to supply power to the system electrical' network shall constitute an acceptable demonstration of operability.

. b. During each~ refueling outage, the conditions =under which the gas turbine generator'is required will be simulated and a test l conducted to verify that it will start and be able to accept emergency loads within 48 seconds.

LIMITING CONDITION FOR OPERATION 3.9 AUXILIARY ELECTRICAL SYSTEM B. When the mode switch.is in RUN, the availability of power shall be as specified in 3.9 A, except as specified below:

1. From and after the date that power is available from only one 345 kv l line,' reactor operation is permissible only during the succeeding seven days unless an additional 345 kv line is sooner placed in service.

2. From and after the date that incoming power.is not.available from any, 345 kv line, reactor operation shall be permitted provided both emergency power sources are operable. The NRC shall be notified, within 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />, of the precautions to be taken during this situation and the plans for restoration of incoming power.

' Generator experience at other generating stations indicates that the testing frequency is adequate to assure a high relisellity of operation should the system be required. In addition, during the test when the i generator is synchronized to the bus it is also synchronized t,o the off-To site power source and thus not completely independent of, this source.

Both the diesel generator and the gas turbine-generator have air .

compressors and air receiver tanks for starting. It is expected that the air compressors will run only infrequently. During the monthly check of

compressors to recharge the receivers. Pressure indioators are provided on each of the receivers.

Following the tests or peaking operation, of the unit and at least week 1,y, the fuel volume remaining will be checked. At the end of the monthly load test of the diesel generator, the fuel oil transfer pump will be operated Peaking to refill the day tank and to cheok the operation of this pump.

operation shall be controlled so that major maintenance operations on the gas turbine will not be scheduled during an operating cycle.
