INTRODUCTION A.

Overview 1.

This lesson describes the relationship of the Emergency Diesel Generators (EDG's) with the plant's offsite and onsite electrical systems, and explains the purpose of the EDG's and the purposes of the EDG's auxiliary systems, and introduces several major components of the auxiliary systems 2.

LESSON PRESENTATION l

A.

General Overview FSAR Q.430.1 Commitment l

1.

The emergency diesel generators provide j

standby onsite oower required by the class it i

AC power systems in the event of a loss of preferred power sources, for powering the essential loads necessary to safely shut down the reactor under any operating and accident conditions a.

The EDG provides standby power to the 4160V Class IE busses during all loss of l

offsite essential power conditions l

b.

The RDO is D21 designed to perform any main generator power generator functions 6

Lo-LP-11001-06-c III.

LESSON CUTLINE:

HOTES 2.

4160 V class IE busses Class IE system divided into two redundant a.

trains / unit each train capable of safely shutting down the unit 1)

ESF busses (1AA02, 1BA03 for unit 1 are class 12 busses) 2)

BOP (balance-of-plant) 4160 V busses are non-class 1E b.

Two Reserve Auxiliary Transformers (RAT's) 1)

Receive 230 KV from system busses 2)

Supply 13.8 KV and 4.16 KV 3)

The 4.16 KV from the RAT supply the 4.16 KV class 1E busses Each class 1E bus is provided:

c.

1) Normal offsite preferred power source (breaker from its normal RAT. closed)
2) Alternate offsite power source (breaker from opposite trains RAT is not in the compartment - only one breaker between the 2 RAT sources)
3) Standby Power Source Diesel generator d.

Normal Plant Operation: Both class 1E 4160 V busses energized from the offsite preferred power sources, and each class 1E standby diesel generator is not running but available for autom,atic start Loss-of-Offsite Powers With one or both e.

offette power sources not available, the 1

loads on the de-energized system (s) are shed from the busses and re-er.6rgized from the class IE standby diesel generatork by a sequencer f.

Accident conditions: On a safety injection actuation signal, both EDC's for that unit automatically start and are made available to supply the respective 4160 V class IE busses should offsite power subsequently occur 7

4-Stroke Diesel Engines:

1.

Advantages over gasoline engines:-

Diesel does not need electric spark a.

ignition, relies instead gn heat of compression (approx. 1000 F)-

b.

Fuel oil burns at approx. 450 F, so is less of a fire hazard from gasoline Fuel oil can be stored longer c.

Operates on a 4-stroke principle LO-TP-11001-003 b.

Air Intake Stroke 1)

Intake valve open i

2)' Piston moves down, drawning air into cylinder 3)

Intake valve shuts near the bottom of the stroke c.

Compression Stroke 1)

Cylinder sealed and air is compressed 2)

Air temperature increases under compression 3)

Fuel injected at top of stroke and ignites from high temperature d.

Power Stroke 1)

Heat of-combustion expands gassesE

' forcing the piston downward

2) Exhaust valve _ opens just before bottom of power stroke i

e.

Exhaust' Stroke-1)

Piston moves upward expelling gasses' from cylinder through exhaust valve

2) Air intake valve opens just prior to end of exhaust stroke to aid in-purging exhaust gasses and cooling the inner cylinder walls l
