Introduction (A!P-54

.............

The US-APWR uses Gas Turbine Generators(GTG), as Emergency Power Supply (EPS) in lieuof the commonly used Diesel Generators (DG).

The reasons for the selection of the GTG are asfollows:

a. The Gas Turbine is a very simple rotatingengine with few components

b. The GTG System consists only of the gasturbine, generator, fuel transport, starting andcontrollinstrumentation systems

c. Water cooling system is not required

d. The GTG presents a high level of reliability.

I=JUM- H-A V-IjNDMJ•US RES, LTD. 4GG-UAP-200O80025-7=

Background

) The application of an aircraft derivative gasturbine for electrical power generation is neededin order that the "fast start" requirement foremergency core cooling could be met. Thisresulted in the combination of an extremelyreliable aircraft component with equally reliableindustrial components such as reduction gears,electrical generator, governor, voltage regulator,relays and similar components. The advanceaccumulator design of the US-APWR allows astarting time for the GTG of within 100 seconds.

Capability(2/4)

Standby generator sets must start and supply power in theevent of the loss of power from the utility.

These functions rely on the prime-mover of the standbysystem.

Kawasaki standby GPS Series are suitable for standbypower supply when utility power is lost.

All the models are designed for automatic operation (start/powersupplylstop) and equipped with alarm/trip protection systems.

THE FEATURE OF Kawasaki GAS TURBINE

1. No cooling water is required.* are therefore more reliable for emergency starts.

QAP5ij;-

2. Easy to reduce the noise level (sound power level)= the sound noise frequency is very high (peak: 1 to 4 kHz).

3. Less vibrationthe gas turbine is a rotating machine.

4. Hiah seismic resistance=' Kawasaki gas turbines have high seismic performance experience

even in the area that experienced seismic intensities of 6 or 7.

5. Hiah reliability of startina

==> no warm-up running is required.

Capability(4/4) "Lwm

THE FEATURE OF Kawasaki GAS TURBINE

6. Less maintenance

Overhaul maintenance is typically required only 1 time / 15 years.

7. High stability of the voltagelfrequency=> because the Kawasaki gas turbine has a single shaft turbine.= single shaft turbine is suitable for the stable power generation.

8. High overload capacity

=> the rotation speed of the gas turbine is very high andthe equivalent moment of inertia becomes very big.This effect gives gas turbine a high electrical overload capacityduring electrical transients.

9. Compact installation* weight 1/4, volume 1/7 compared with the same range diesel

engine.10. Clean emission

= exhaust gas is cleaner compared with the same range diesel engine.

It is designed not to bring the vent air to the air intake chamber and every air ductsystem should be designed appropriately.

Air Intake(3/3)

GAS TURBINE INTAKE DUCT CRITERIA

The amount of inlet air pressure loss, difference between atmospheric pressure and stagnation pressure atupper inlet collector flange, has to be less than 980 Pa.

Because this pressure loss decreases the engine performance it must be fed back to the performance ofoutput.

It is necessary to design a suitable inlet sound absorber which reduces the inlet noise of gas turbine engine,according to the specifications set by customer. Spli ter-type inlet silencer is desirable, which causes little

pressure loss and hardly disturbs air flow.

When using the sound absorbing material, secure protection have to be provided not the material to beblown off the air flow. Maximum air velocity at the sound absorber surface shall not exceed 98 ft/sec (30m/sec).

To avoid F.O.D.(Foreign Object Damage), an inlet screen shall be installed at the intake dividing flange ofgas turbine engine.

VENTILATION CRITERIA

For packaging, ventilation is necessary lest the temperature inside the enclosure should exceed thepermissible limit.

There are three heat sources as follows,

a) Exhaust air from generator (air cooing type)

b) Exhaust air from oil cooler (air cooling type)

c) Heat radiation from the surface of gas turbine engine

In the case that the generator and oil cooler are of the air cooling type, a bulkhead shall be laid betweenengine room and generator room, or some other suitable ventilation system shall be designed lest exhaustair (hot air)should come near to the inlet side.
