ELECTRICAL POWER SYSTEMS SURVEILLANCE REQUIREMENTS 4.8.1.1.1 Each of the above required independent circuits between the offsite transmission network and the onsite Class lE distribution system shall be:

a.

Determined OPERABLE at least once per 7 days by verifying correct breaker alignments and indicated power availability, and b.

Demonstrated OPERABLE at least once per 18 months 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 STACCERED TEST BASIS by:

c 1.

Verifying the fuel level in the engine-mounted fuel tank, 2.

Verifying the fuel level in the day fuel tank, 3.

Verifying the fuel transfer pump can be started and transfers

- /

fuel from the day tank to the engine mounted tank, 4.

Verifying the diesel starts and accelerates to at least 514 rpm in less chan or equal to 10 seconds,*

5.

Verifying the generato is synchronized, loaded to greater than or equal to 1750 kw, anc operates for greater than or equal to 15 minutes, and B

6.

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

I b.

At least once per 31 days by verifying the fuel level in the plant fuel storage tank.

M c.

At least once per 92 days by verifying that a sample of diesel fuel i

from the fuel storage tank, obtained in accordance with ASTM-D270-65, is within the acceptable limits specified in Table 1 of ASTM-0975-74 when checked for viscosity, water and sediment, 9

1 The diesel generator start (10 seconds) from ambient conditions shall be performed at least once per 184 days in these surveillance tests. All other engine starts for the purpose of this surveillance testing may be preceded by a manually initiated engine prelube period and/or other warmup procedures recommended by the manufacturer so that mechanical stress and wear on the diesel engine is minimized.

(BSEP-2-96) a SURVEILLANCE REQUIREMENTS (Continued) d.

At least once per 18 months during shutdown 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 equal to one core spray pump without tripping, 3.

Simulating a loss of offsite power in conjunction with an emergency core cooling system test signal, and:

a)

Verifying de-energization of the emergency buses and load shedding from the emergency buses.

b)

Verifying the diesel starts from ambient condition on the auto-start signal, energizes the emergency buses with permanently connected loads, energizes the auto-connected loads through the load sequence relays and operates for greater than or equal to 5 minutes while its generator is

-loaded with the emergency loads.

4.

Verifying that on the emergency core cooling system test signal, all diesel generator trips except engine overspeed, generator differential, low lube oil pressure, reverse power, loss of field and phase overcurrent with voltage restraint, are automatically bypassed.

5.

Verifying the diesel generator operates for greater than or equal to 60 minutes while loaded to greater than or equal to 3500 kw.

6.

Verifying that the auto-connected loads to each diesel generator do not exceed the 2000 hour0.0231 days 0.556 hours 0.00331 weeks 7.61e-4 months rating cf 3850 kw.

7.

Verifying that the automatic load sequence relays are OPERABLE with each load sequence time within 10% of the required value.
