PERFORMANCE ORTECTIVE Given a directive frun the control room, marmally start the diesel generator locally.
The turbochartger bearings mst be pre-lubed.
Upcn start, the diesel generator operating parameters nust be nonitored.
All coimunicatior6and activities nust be performed in accordance with current, approved procedures. All data sheets nust be canpleted, initialled, and returned to the Shift Supervisor.
INFORMATION This task is performed after the followirry prerequisites have been met:
The diesel has been prepared for startup in accordance with Plant Vogtle Procedure 13145-1, the Fuel Oil System has been aligned per Plant Vogtle Procedure 13146-1, the Inbe Oil ard Jacket Feep-Warm System are operating, and the generator heater is operatiry in the autmatic mode. -The NSCW is aligned to provide cooliry water to the diesel generator jacket water cooler, and is in operation. The Diesel Gererator Fuel Oil Transfer System is aligned per procedure 11146-1, and the fuel oil day tank is aligned for autcnatic filling per procedure 13146-1.
The diesel may have to be started locally for tasting purposes or after prescheduled maintenance to test normal operation.
The diesel may also be started locally and run to generate heat, if temperatures in the diesel generator buildirr3 fall below 50 degrees F.
If more than four hours have elapsed since a cylirder moisture check has been performed, the wui.wl room operator will direct another check prior to the start. For this task, assume that four hours have not elapsed. The cylirder moisture check is covered in another Instructional Unit.
l "he diesel is aligned and in the STANDBY mode before' it is started locally or remotely. The control rom operator will Mw a directive to start the diesel locally after it has been prepared for startup.
In _ this Instructional Unit, diesel-generator train A nunbers (valves, L
breakers, etc.) will be followed by train B numbers in parentheses where L

This will render the train _ A diesel generator.
inoperable. The train B diesel generator nust be operable in the event that train A is not. The control rocan is aware of the status of the train 2-1 l

NIrIU-11205-002-01-C; Marually Start the Diesel Gemrator Iocally B diesel generator; however, checking both of the diesel generators ensures that this requirenent is satisfied.
Clear the brief check of the other DGs rocan with your control room operator, in case the startirg of the assigned ergine is urgent.
Review Procedure 13145-1, " Diesel Generator" if you need further instruction on how to survey the diesel rocxts for rmviiness.
1.
Quickly check, in both the train A and train B diesel generator rocans, for cbvious oil, air, or water leaks, and for alarm on the annunciator board on the ergine control panel.
2.
luke sure that the fire protection deluge valves are not isolated, ard that there is pressure at the fire hose reel station.
The fire protection deluge valve for the A train diesel generabr recra is in the B train diesel generator rocan, ard the B train deluge valve is in the A train diesel generator rocan.
3.
Verify that the UNIT AVAIIABIE light is illuminated.
This check of the train B diesel rocan should take In 1 tore than 2 or 3 minutes.
4.
Ibrfom a lanp check on the train A diesel control panel.
5.
Check ard icg, in the diesel generator log book, the diesel generator fuel oil day tank level, the lube oil su@ level, and the ergine houmeter readirq.

Notify the cchul rocan that the diesel generator is ready to be placed in the IDCAL control.
(A cylirder noisture check has already been perfomed per 13145-1).

Ackrnwledge the follcwirq alarms:
1.
Acknculedge the DGINE CONITOL IN IDCAL alarm on the PD32(4) ergine control panel.
Call the control rocan and notify the operator of the cause of the alam. In many ins +m, the centrol roca cperator will place the cuhul tocan switch for the genarator output breaker in the IULL TO IDCK position.
