Se Inbricating Oil Systan sunp tanks nust be correctly filled to the required level. %e Startirg Air System tust be pressurized. The fuel Oil System nust be available.
%e Jacket Water Systan nust be filled ard vented correctly;irg through the jacket water heat exchanger; and thethe nuclear aligned ard flow generator space heater nust be on.
The diesel generator controls must be in the MAIlGDIAlU made and the IDCAI/RDUTE control switch nust be in the 10 CAL position.
Se task is crrplete when the generator is in the starc-by rode.
All cumunication ard activities nust be performed in accordance with curmnt, approved procedumc.
INFORMATICH This task is performed when the diesel generator has been shut down for maintenance or for any other reason.
It may take up to 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> for the jacket water and lube oil heaters to brirg up ard stabilize the jacket water ard oil tecperature for startup.
Powr nust be provided to the starting air dryer at least 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> before startirg.
An alignment of the diesel buildirq HVAC system ard fuel oil storage l
systems is performed before the major empcnents to the diesel generator will be placed in service.
In order to verify that the other diesel generator subsystems are aligned, you will be given a cxmpleted ard verified copy of Plant Vcgtle Procedure 11145-1, " Diesel Generator Alivuunnt for Startup and Normal Operations." %ese subsystems include:
startirg air, fuel oil (day tank ard ergine), lube oil, coolirg water, ard electrical distributicn.
The valve alignments for the diesel generator systans ard the fuel oil systems an assumed to be ccupleted per procedure (11145-1, 11146-1) prior to beginning this task.
In this Instructional Unit, diesel generator train A numbers (valves, breakers, etc.) will be followed by train B nu:nbers in parentheses where applicable.
For many maintenance activities, the diesel generator nust be ensured not to start. The 1-2403-X4-765 ard the 1-2403-04-769 DIESEL GEN. A AIR STAkr RECEIVER (#1 AND #2) DISG ISO valves are isolated ard tacpged out.

'Ihe control will inform ycu when to preparn the diesel generator for startup.
Check the oil level of the oil bath air cleaner for the diesel ergine. If the level is low, check for leaks on the flcor.
'Ihe air clearer does not function correctly without oil. A sludge buildup of about one inch in the bottcn reservoir is norml after lon clear of paper or other loose debris.g use. Ihe air inlet screen mst be meck the mffler recu for any flamable material and debris. 'Ihe muffler reca can reach high torperatures after the diesel generator is started.
Righ ta:peratures are especially hazardous if there are any oil spills or flamable material in the area.
Before preparing the system for startup, notify the control roca of the location of any flamable materials.
Ensure that the fire protection deluge valves are r.ot isGlated and that pressure is available at the fire hose reel station. The fire prote: tion deluge valve for the A train diesel generator rocu is in the E train diesel generator rocn/ ard the B train deluge valve is in the A train diesel generator roca.
Ensure there are no burned-out bulbs on the annurciator panel. Replace any burned-out bulbs.
Account for the annunciator alams as follows.
Ensure that the alarms specified are annurciated. If any of the alatts annunciated on the alarm panel differ frora those specified, notify the control roca.
Verify that the DGlA DISARTFn MAINITNANCE IDCK CUT alarm (win $ow E10) has annunciated.
Do not continue with the procedure until this alarm has annunciated. 'Ihis alarm ensures that the diesel has been locked out arri will not start during certain phases of this procedure. Notify the control roca if it is not illuminated.

Ensure that the Demineralized Water System valve is opened first.
Notify the control room to reset the alarm.
Ilttle or no water should have to be added if the jacket u.ter systen was not disturbed durity maintenance.
If excessive water must be added, investigate to see if the water may have leaked into the engine.

Verify that 120V AC pwer is available to the air dryers by verifying i
that th.) amber IWER Of indicating light on the air dryer control i

This is to energize the air dryer empressor crankcase heater, so that the cmpressor oil tenperature is higher than the other system ocrponents, preventing the liquid refrigerant frun accumulating in the empressor while it is shut down.
2.
Ensure the cordenser is free of dirt and foreign objects. If it is I
curty, notify the control room to initiate an MWo. The cordenser is the part o'f the dryer that looks similar to an autcraabile radiator.
3.
Use a flashlight to visually inspect. the two parallel drive belts (fan belts) on the air capressor beneath the belt guard.
I.cok for frays and loose parts.
Feep your hards clear of the belts.
4.
Check the oil level in the air ccrpressor crankcase by unscrewing ard ruravirg the dipstick, wiping ard reinserting it, ard checking the level ard reinstalling it.
5.
Start the 1-2403-G4-001(002)-K01 (102) air dryer refrigeration unit frun the air dryer control panel by depressing the black pushbutton with the
'I' inscribed on it-The dryer runs cxantinuously, whether or not the air cxxpressor is runnity.
The red EIGI TDiP light 'is expected to illuminate just after the air dryer starts. The light will go out after the air has cooled (approximately 15 minutes).
6.
Energize the air after-cooler fan 1-2403-G4-001(002)-E01(E02), at MCC INBI(1NBO), by placing the lccal haniswitch to the AUIO position.
Independent verification will be required for that handswitch.
7.

It is inportant that the three control knobs on the governcr must never be tanpered with. The settings are, in very basic terms:
-Speed Droop. This is a function of how nuch the ergine speed would try to charge going frun no load to full Iced. The speed droop control helps conpensate that charge.
-Lced Limit Knob. Sets the maxirum limit that the nrvtanical portion of the governor will allow. Usually set at MAX FUEL.
-Speed Settiry Knob. This settirg can v from ergine to ergine, and detennines the speed at which the cal governor will control (approximtely 470 rpn).
Special attention nust be given to the governor.

Examine the linkage frun the shutdown cylinder to the fuel racks, and the linkage to the two ccanbustion air danpers.
At a nuclear plant that also used a Transamerica Delaval diesel with a Woodward governor, a diese.1 overspeed occured for about 15 seconds on a startup followirs preventive maintenarce on the governor.
It is postulated that inadeqmte filling and venting of the governor, alcrg with a slowly reponding overspeed trip protective device, allowed the diesel to l
overspeed. Numw engine cxxporents were damged, ircluding Lt:ds, rod bearings, ard main bearings.
