2. What is Nuclear Energy?
“A large amount of Energy is obtained by the splitting
of heavy nuclei (e.g Uranium) which is called Nuclear Energy.”
• This heat Energy can be used to generate electricity or to propel rockets in
space. It is used in nuclear weapons for destruction.

3. Nuclear Energy Generation:
 Nuclear Energy is generated on large scale in Power Plants through fission
chain reactions. 11.01% of world’s electricity is obtained by Nuclear Energy.
 A nuclear chain reaction occurs when one nuclear reaction causes an average
of one or more nuclear reactions, thus leading to a self-propagating series of
these reactions emitting a large amount of energy which is then used to
produce steam to drive generators.

4.  Nuclear Energy: Source of Electric Power:
 A nuclear power plant is a thermal
power station in which ,the heat source
Is a nuclear reactor, the heat is used to
generate steam which drives a steam
turbine connected to a generator which
produces electricity.
Three Nuclear reactors
are operating in Pakistan
Producing 725MW while
three are in progress
As of 16 January 2013,
the IAEA report there are
439 nuclear power reactors
in operation operating in
31 countries.

Aircrafts &
Spacecrafts

6.  Nuclear Energy: Source of Destruction:
 Atomic Bomb:
Atomic bomb is a weapon with great explosive power that
results from the sudden release of energy upon the splitting,
or uncontrolable fission chain reaction, of the nuclei of such
heavy elements as plutonium or uranium.
 The detonation of an atomic bomb releases enormous
amounts of thermal energy achieving temperatures of
several million degrees within region of 3-4 km.
 The radiations emitted during explosion are long-lived
and have damaging effect on human health even after
many years of explosion
Did you know??
In 1945, Atomic bombing on Hiroshima & Nagasaki killed 246,000+
people. Thousands were injured and effected by radiations.
