3. Verifying that samples of diesel fuel from the day tanks and the fuel storage tanks are within the acceptable limits specified in Table 1 of ASTM D975-78 when checked for viscosity, water and sediment,

4. Verifying the fuel transfer pump can be started and transfers fuel f rom the storage system to the day tank,

5. Verifying the diesels start from ambient condition,

6. Verifying the generator is synchronized, loaded to 21690 kw, and operates for 2 60 minutes with both diesel engines operating, and

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

b. At least once per 18 months during shutdown by:

1. Subjecting the diesels to an inspection in accordance with procedures prepared in conjunction with its manufacturer's reconsnendations for this class of standby service,

2. Verifying the generator capability to reject a load of 2 828 kw without tripping,

3. Simulating a loss of offsite power with and without the presence of a safety injection signal, and:

a) Verifying de-energization of the emergency busses and load shedding from the emergency busses.

b) Verifying the diesels start from ambient condition on the auto-start signal, energize the emergency busses with permanently connected loads, energize the auto-connected emergency loads through the applicable load sequencer and operate for 2 5 minutes while the generator is loaded with the emergency loads, c) verifying that all diesel generator trips, except engine overspeed, fail-to-start, generator phase l overcurrent, generator neutral overcurrent or generator loss of field, are automatically bypassed upon loss of voltage on the emergency bus and/or safety injection actuation signal.
