5. During shutdown, simulating a loss-of-offsite power in conjunction with an SIAS actuation test signal, and a) Verifying deenergization of the emergency busses and load shedding from the emergency busses.

b) Verifying the diesel starts on the auto-start signal, energizes the emergency busses and the permanently connected loads within 10 seconds after the auto-start signal, energizes the auto connected emergency loads through the load sequencer and operates for greater than or equal to 5 minutes.
