SURVEILLANCE REQUIREMENTS (Continued)
- 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 6 E FOEuNrr .ToTERVAL
- b. Demonstrated OPERABLE at least once per -18 ;rsrthe during shutdown i 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 3TAGGERED 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 accelerates to at least 900 rpm with generator voltage and and 60 1 1.2 Hz, respectively., frequency at 41601420 volts
- 5. Verifying the generator is synchronized, loaded to 31250 kW, and operates for E 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.
- 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.
All engine starts for the purpose of this Surveillance Requirement i
may be preceded by an engine prelube period and/or other warmup procedures recommended by the manufacturer so that mechanical wear and stress on the diesel engine is minimized.
