` Nuclear powergenerally refers to electrical power

generated from controlled nuclear reactions.

Commercial plants in use to date use nuclear

fission reactions.` Just as many conventional thermal power stations

generate electricity by harnessing the thermal

energy released from burning fossil fuels, nuclear

power plants convert the energy released from thenucleus of an atom, typically via nuclear fission.

` An induced fission

reaction. A slow-

moving neutron is

absorbed by thenucleus of a uranium-

235 atom, which in

turn splits into fast-

moving lighter

elements and three

free neutrons.

Nuclear reactor is the main part of power plant.

Fission takes place in reactor building. It transports steam to the turbine.

Nuclear reactor consist of calandria ,moderator.

` It is the heart of reactor and

contains fuels and moderators.` It is made of austenitic stainless

steel .

` It has 306 horizontal calandriatubes .

` It is a device used to generate steam.

` There are 4 boilers of steam generators.

` These are the unit where the high pressure andhigh temperature water gives away the thermal

energy to low pressure water

` Hence it gets converted into steam.

Turbine is a device used to convert hydraulic

energy in mechanical work.

Turbines are of two types:- Impulse turbine( pelton turbine)

Reaction turbine(francis & kaplan turbine)

In R.A.P.S impulse turbine is used which runs

at 3600 R.P.M

` Cooling towers are

heat removal devices

used to transfer waste

heat to the

atmosphere.

` The towers vary in size

from small roof-top

units to very large

hyperboloid structures

or rectangular

structures

` Nuclear fuel is any material that can be

consumed to derive nuclear energy.

` Nuclear fuel is heavy fissile elements that can bemade to undergo nuclear fission chain reactions in

a nuclear fission reactor.

` The most common fissile nuclear fuels are 235Uand 239Pu


21/23

` They consist of235U

pellets in zirconium alloy

tubes.

` Fuel bundles are about a

half meter in length and

10 cm in diameter.
