8) Verifying that the auto-connected loads to each diesel generator do not  !

exceed 6201 kW:

9) Verifying the diesel generator's capability to: f i

a) Synchronize the offsite power source while the generator is loaded i with its emergency loads upon a simulated restoration of offsite power, l b) Transfer its loads to the offsite power source, and c) Be restored to its standby status. ,

10) Verifying that with the diesel generator operating in a test mode, connected to its bus, a simulated Safety injection signal overrides the test l mode by: (1) returning the diesel generator to standby operation, and (2) I automatically energizing the emergency loads with offsite power:

11) Verifying that the fuel transfer pump transfers fuel from each fuel storage tank to the day tank of each diesel via the installed cross-connection #

lines; E

12) Verifying that the automatic LOCA and shutdown sequence timer is
