SURVEILLANCE REQUIREMENTS 4.8.1.1.1.

Each required independent circuit between the offsite transmission network and the onsite Class lE distribution system shall be:

a.

Demonstrated OPERABLE, as fo.11ows:

1.

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

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 0.00222 hours 1.322751e-5 weeks 3.044e-6 months thereafter during use by verifying correct breaker alignments and indicated power availability; and b.

Demonstrated OPERABLE at least once per 18 months during shutdown by manually transferring ur.!t power supply from the nomal circuit to the alternate circuit.

4. 8.1.1. 2 Each diesel generator shall be demonstrated OPERABLE:

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

a.

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 accelerates to at least 900 rpm with generator voltage and frequency at 4160 + 420 volts and 60 + 1.2 Hz, respectively.*

5.

Verifying the generator is synchronized, loaded to > 1250 kW, and operates for > 60 minutes.

6.

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

t

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