ABSTRACT
Nuclear energy is the energy in the nucleus of an atom.
In other words Nuclear energy is the energy that holds
neutrons and protons of an atom.
Nuclear energy is used to produce electricity. This
energy can be obtained in two ways: nuclear fusion and
nuclear fission. In nuclear fission, atoms are split into
smaller atoms, releasing energy. Actually, nuclear power
plants use nuclear fission to produce electricity.

INTRODUCTION TO RAPS
The Rajasthan Atomic Power Station is located about
65 kms from Kota, approximately 3 kms above the dam
that holds the Rana Pratap Sagar lake.
In November 2012, International Atomic Energy
Agency(IAEA) intensively audited two reactors at the
Rajasthan Atomic Power Station for safety. It has
concluded that the reactors are among the best in the
world, and can withstand a Fukushima type of accident,
and that India emerged a winner with a high global
safety rank.

BASIC PRINCIPLE
Fission occurs
in the reactor
vessel. Heat is
produced.
The heat is
used to heat
water to create
steam
The steam is
used to turn
the turbine in
the generator
to produce
electricity
The steam is
cooled in the
condenser to
return to the
liquid phase.
CALANDRIA
It is the heart of reactor and
forms the Core of reactor.
It consists of:-
Nuclear Fuel
Control Rods
Pressure Tubes
Moderator
STEAM GENERATOR
It is used to convert water into steam from heat
generated in nuclear reactor.
Steam contains more kinetic energy than liquid.
That’s why we use steam instead of liquid water.
TURBINE
It converts the kinetic
energy of steam into
mechanical energy.
A turbine consists a
stationary set of blades
called stators and moving
sets known as rotors.
These two blades act
together to allow flow of
steam to do all the work.
In R.A.P.S. impulse turbine
is used which runs at 3000
R.P.M.
GENERATOR
It is used to convert the
mechanical output of
turbine into electrical
output.
It is connected to
turbine by means of a
shaft, which provides
the output of turbine to
the generator.
Here we run the
generator at a rotation
speed of 3000 RPM.
COOLING TOWERS
It consists of a shell and
is open at top and bottom.
Purpose is to bring down
the temperature of light
water
There are two types of
cooling towers:-
(1) Natural Draft Cooling
Towers
(2) Mechanical Draft Cooling
Towers (Forced draft and
induced draft)
Lower Greenhouse Gas Emissions
Cheap Electricity
Reliable
Nuclear reactions release a million times
more energy, as compared to hydro or
wind energy.
High amount of energy can be generated
from a single nuclear power plant.
The initial capital cost is very high.
Nuclear explosions produce radiation.
The fuel used is expensive and
difficult to recover.
The disposal of the products, which
are radioactive, is a big problem.
The cooling water requirements of a
nuclear power plant are very heavy.
