SURVEILLANCE RE0VIREMENTS (Continued) 5)
Verifying that on an ESF actuation test signal, without loss-of-offsite power, the diesel generator starts on the auto-start signal and operates on standby for greater than or equal to 5 minutes. The generator voltage and frequency shall be at least 4160 volts and 57 Hz within 11 seconds after the auto-start signal; the steady-state generator voltage and frequency shall be maintained within 4160 i 420 volts and 60 i 1.2 Hz durino this test; 6)
Simulating a loss-of-offsite power in conjunction with an ESF actuation test signal, and a)
Verifying, during shutdown, deenergization of the emergency l
busses and load shedding from the emergency busses; b)
Verifying, during shutdown, the diesel starts on the auto-l start signal, energizes the emergency busses with permanently connected loads within 11 seconds, energizes the auto-connected emergency (accident) loads through the load sequencer and operates for greater than or equal to 5 minutes while its generator is loaded with the emergency 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; and c)
Verifying, during shutdown,* that all automatic diesel l
generator trips, except engine overspeed, lube oil pressure, and generator differential are automatically bypassed upon loss of voltage on the emergency bus concur-rent with a Safety Ip'^ction Actuation signal.

Verifying, during shutdown, the diesel generator operates for at l
least 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />. During the first 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> of this test, the diesel generator shall be loaded between 4200 kW and 4400 kW**
l and during the remaining 22 hours2.546296e-4 days <br />0.00611 hours <br />3.637566e-5 weeks <br />8.371e-6 months <br /> of this test, the diesel generator shall be loaded between 3800 kW and 4000 kW.**
The j
generator voltage and frequency shall be at least 4160 volts and 57 Hz within 11 seconds after the start signal. The steady-state generator voltage and frequency shall be maintained within 4160 1 420 volts and 60 i 1.2 Hz during this test. Within 5 minutes of shutting down the diesel generator, restart the diesel generator and verify that the generator voltage and frequency reaches at least 4160 volts and 57 Hz within 11 seconds.***
