3/4.8 ELECTRICAL POWER SYSTEMS SURVEILLANCE REQUIREMENTS 4.8.1.1.1 Each required independent circuit between the offsite transmission network and the onsite Class 1E Dittribution System shall be:

a.

Demonstrated OPERA 8LE, as follows:

1.

For each 500 kV offsite circuit, at least once per 7 days by verifying correct breaker alignments and indicated power availability.

2.

For the 69 kV SMECO offsite power circuit, within one hour of substitution for a 500 kV offsite power circuit, and at least once per 8 hours9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br /> thereafter during use by verifying correct breaker alignments and indicated power availability; and b.

Demonstrated OPERABLE at least once per REFUELING INTERVAL during shutdown by manually transferring unit power supply from the normal circuit to the alternate circuit.

4.8.1.1.2 Each diesel generator shall be demonstrated OPERABLE:

a.

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

1.

Verifying the fuel level in the day fuel tank.

2.

Verifying the fuel level in the fuel storage tank.

3.

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

4.

Verifying the diesel starts and achieves a generator voltage and frequency,0f 4160 1 420 volts and 6011.2 Hz, respectively.

5.

Verifying the generator is synchronized, loaded to E 4000 kW for No. lA Emergency Diesel Generator or 2 2700 kW for No. IB l

Emergency Diesel Generator, and operates for > 60 minutes.

6.

Verifying the diesel generator is aligned to provide standby power to the associated emergency busses.

7.

Verifying that the automatic load sequencer timer is OPERABLE with the interval between each load block within i 10% of its design interval.

All engine starts for the purpose of this Surveillance Requirement may be preceded by an engine prelube period and/or other warmup procedures recomended by the manufacturer so that mechanical wear and stress on the diesel engine is minimized.

CALVERT CLIFFS - UNIT 1 3/4 8-4 Amendment No. 224

3/4.8 ELECTRICAL POWER SYSTEMS SURVEILLANCE REQUIREMENTS (Continued) b.

At least_once per 92 days by verifying that a sample of diesel fuel from the fuel storage tank is within the acceptable limits specified in Table 1 of ASTM D975-81 when checked for viscosity, water and sediment.

c.

At least once per 184 days by verifying the diesel starts from ambient condition and accelerates to at least 60 Hz in 5 10 seconds.*

d.

At least once per REFUELING INTERVAL by:

1.

Subjecting the diesel to an inspection in accordance with procedures prepared in conjunction with its manufacturer's recommendations for this class of standby service.

2.

Verifying the generator capability to reject a load of 1 500 hp without tripping.

3.

Simulating a loss of offsite power in conjunction with a safety injection actuation test signal, and:

a) Verifying de-energization of the emergency busses and load shedding from the emergency busses, b) Verifying the diesel starts from ambient condition on the auto-start signal, energizes the emergency busses with permanently connected loads, energizes the auto-connected emergency loads through the load sequencer and operates for 15 minutes while its generator is loaded with the emergency loads.*

c) Verifying that automatically bypassed diesel trips are automatically bypassed on a Safety Injection Actuation Signal.

4.

Verifying the diesel generator operates for 160 minutes while loaded to 3 4000 kW for No. IA Emergency Diesel Generator or t 3000 kW for No. IB Emergency Diesel Generator.
