52 4.4 EMERGENCY POWER SYSTEM PERIODIC TESTING Applicability: Applies to testing of the Emergency Power System.

Objective:

To verify that the Emergency Power System will respond promptly and properly when required.

Specification: A. The required offsite circuits shall be determined OPERABLE at least once per 7 days by verifying correct breaker alignments and power availability.

B. The required diesel generators shall be demonstrated OPERABLE:

1. At least once per 31 days on a STAGGERED TEST BASIS by:

a. Verifying the diesel starts from standby conditions,

b. Verifying a fuel transfer pump can be started and transfers fuel from the storage system to the day tank,

c. Verifying the diesel generator is synchronized and running at 4500kW +/-5% for 60 minutes,

d. Verifying the diesel generator is aligned to provide standby power to the associated emergency buses,

e. Verifying the day tank contains a minimum of 290 gallons of fuel, and

f. Verifying the fuel storage tank contains a minimum of 37,500 gallons of fuel.

2. At least once per 3 months by verifying that a sample of diesel fuel from the required fuel storage tanks is within the acceptable limits as specified by the supplier when checked for viscosity, water and sediment.

C. AC Distribution

1. The required buses specified in Technical Specification 3.7, Auxiliary Electrical Supply, shall be determined OPERABLE and energized from AC sources other than the diesel generators with tie breakers open between redundant buses at least once per 7 days by verifying correct breaker alignment and power availability.

Amendment No. 28, 50, 82, $4, 95

53b

2.

Simulating SISLOP, and:

a. Verifying operation of circuitry which locks out non-critical equipment,

b. Verifying the diesel starts from standby condition on the auto-start signal, energizes the emergency buses with permanently connected loads and the auto connected emergency loads**

through the load sequencer (with the exception of the feedwater, safety injection, charging and refueling water pumps whose respective breakers may be racked-out to the test position) and operates for 25 minutes while its generator is loaded with the emergency loads,

c. Verifying that on the safety injection actuation signal, all diesel generator trips, except engine overspeed and generator differential, are automatically bypassed.

3. Verifying the generator capability to reject a load of 2611 kW without tripping.

• SISLOP is the signal generated by coincident loss of offsite power (loss of voltage on Buses 1C and 2C) and demand for safety injection.

The sum of all loads on the engine shall not exceed 4500kW + 5%.
