A PRESENTATION on PRACTICAL TRAINING Undertake at RAJASTHAN ATOMIC POWER STATION

Rawatbhata

Nuclear potential energy is the potential energy of the particles inside an atomic nucleus. Nucleus consists of neutrons, protons and electrons.The nuclear particles are bound together by the strong nuclear force which is known as nuclear energy.

• RAPS comes under N.P.C.I.L (Govt. of India)

• It is situated at the bank of Chambal River of Rana Pratap Sagar Dam

• RAPS Setup in Rawatbhata, Rajasthan• It has following plants• RAPS 1(150MWe) & 2(200MWe)• RAPS 3&4(2×220MWe)• RAPP 5&6(2×220MWe)

*Fusion reactions

*Fission reactions

Nuclear fission is a nuclear reaction in which the nucleus of an atom splits into smaller parts (lighter nuclei), often producing free neutrons and photons (in the form of gamma rays).

Nuclear fission diagrammatic representation

U235 + n → fission + 2 or 3 n +

200MeV

When a neutron strikes an atom of uranium,

the uranium splits into two lighter atoms and

releases heat simultaneously.

Fission of heavy elements can release large

amounts of energy both as electromagnetic

radiation and as kinetic energy of the fragments

A nuclear reactor is a device in which

nuclear chain reactions are initiated,

controlled, and sustained at a steady

rate, as opposed to a nuclear bomb, in

which the chain reaction occurs in a

fraction of a second and if uncontrolled

causing an explosion.

CONTROL RODS

A control rod is a rod made of chemical

elements capable of absorbing many neutrons.

They are used in nuclear reactors to control

the rate of fission of uranium and plutonium

The control rods essentially contain neutron

absorbers like, boron, cadmium or indium.

TURBINES

A turbine is a rotary engine that extracts energy from a fluid flow and converts it into useful work.The simplest turbines have one moving part, a rotor assembly, which is a shaft or drum with blades attached.

CONDENSER The objective of the condenser are to

reduce the turbine exhaust pressure to

increase the efficiency and to recover high

quality feed water in the form of condensate

& feed back it to the steam generator

without any further treatment.

Condenser is a device or unit which is used

to condense vapor into liquid.

Water circulating

through the

condenser is taken to

the cooling tower for

cooling and reuse.

Cooling towers are

heat removal devices

used to transfer

process waste heat to

the atmosphere.

Nuclear Power

ADVANTAGESNuclear power costs about the same as coal,

so it's not expensive to make.

Does not produce smoke or carbon dioxide, so it does not contribute to the greenhouse effect.

Produces huge amounts of energy from small amounts of fuel.

Produces small amounts of waste.

Nuclear power is reliable.

DISADVANTAGES High risks: It is technically impossible to build a

plant with 100% security.

The energy source for nuclear energy is

Uranium. Uranium is a scarce resource, its supply

is estimated to last only for the next 30 to 60

years depending on the actual demand.

Nuclear power plants as well as nuclear waste

could be preferred targets for terrorist attacks..

During the operation of nuclear power plants,

radioactive waste is produced, which in turn can

be used for the production of nuclear weapons.

After completing my training I just wont to conclude that the knowledge of book

that is not sufficient. The practical knowledge is also necessary to become a successful engineer. To support it I would

like to write two lines;TAKE RISKS: IF YOU WIN, YOU WILL BE

HAPPY; IF YOU LOSE YOU WILL BE WISE. The training period was really very

edifying and enlightening experience for me. I come to know about the industry

and the field, the production and management of such life scary radiation and new techniques. This had helped me a lot to develop my technical expertise

and knowledge.
