3. Within 2 weeks after obtaining the sample, verify that the other

h. At least once per 18 months #,1% during shutdown, by:

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

2. Verifying the diesel generator capability to reject a load of 3 greater than or equal to that of the RHR pump motor (1003 kW) for each diesel generator while maintaining voltage at 4160 i 420 volts and frequency at 60 i 1.2 Hz.

3. Verifying the diesel generator capability to reject a load of 4430 kW without trippi,ng. The generator voltage shall not exceed 4580- volts during and following the load rejection.

4785'

4. Simulating a loss of offsite power by itself, and:

. a) Verifying loss of power is detected and deenergization of l the emergency busses and load shedding from the emergency i busses.

b) VSrifying the diest' generttor starts

• on the auto-start signal, energizes the emergency busses with permanently connected loads within 10 seconds after receipt of the start signal, energizes the autoconnected shutdown loads through the load sequencer and operates for greater than or equal to 5 minutes while its generator is loaded with the shutdown loads. After energization, the steady state voltage and frequency of the emergency busses shall be maintained at 4160 420 volts and 60 1.2 Hz during this test.

• This diesel generator start (10 sec) and subsequent loading (130 sec) from ambient conditions may be preceded by an engine prelube period and/or other warmup procedures recommended by the manufacturer so that mechanical stress and wear on the diesel engine is minimized.

1. For any start of a diesel generator, the diesel must be loaded in accordance with the manufacturer's recommendations.
