Nuclear energy comes from nuclear reactions that release energy. It can be generated via two processes: nuclear fission and nuclear fusion. Nuclear fission involves splitting heavy radioactive elements like uranium and produces huge amounts of heat, which is used in nuclear reactors to generate electricity. Nuclear fusion combines light elements to form heavier elements and release energy, but is very difficult to control and cannot currently be used to generate electricity. Nuclear power provides about 5.7% of the world's energy through fission reactions in nuclear reactors. While it has advantages like producing large amounts of energy with low carbon emissions, it also has disadvantages like producing long-lasting radioactive waste that is difficult to dispose of safely.

2. WHAT IS NUCLEAR ENERGY?
• Nuclear energy is a powerfull source of
energy,generated during a nuclear reaction,by
change in the nucleus of atom.
• The source of nuclear energy is the mass of
the nucleus and energy generated during a
nuclear reaction is due to conversion into
energy . This theory is given by EINSTEIN.

3. TWO WAYS TO OBTAIN NUCLEAR
ENERGY:-
1.NUCLEAR FISSION 2.NUCLEAR FUSION

4. NUCLEAR FISSION
• IN NUCLEAR FISSION reaction the nucleus of heavy
radioactive element like uranium,protonium or
thorium splits up into smaller nuclei,when
bombarded by low energy neutrons. A huge amount
of heat is generate d in this process,which is used in
nuclear power plants to generate electricity.
• A device that is used to produce nuclear energy by
controlled fission reaction is called NUCLEUR
REACTORS.
• ATOM BOMB is one of the example of nuclear fission.

7. NUCLEAR FUSSION
• NUCLEAR FUSION reaction involves the combination
or fusion of two light elements to form a heavier
element and release uncontrollable energy.Thus it
can’t be used to generate electricity ,unlike fission
reaction.
• All of u know that the sun’s energy is generated by
nuclear fusion reaction?
• The heat and light that we get from sun,is all due to
the continous reactions going on inside it.We can
now imagine how much energy would be released in
the nuclear fusion,that is the source of sun’s energy

10. IN BREIF
• NUCLEAR POWER is the use of sustained nuclear
fission to generate heat and electricity.Nuclear
power plants provide about 5.7% of the world’s
energy and 13% of world’s electricity.
• There were 439 nuclear power reacters in operation
in the world,operating in 31 countries.
• Enviromentalists for nuclear energy says that nuclear
power is a sustainable energy source that reduces
carbon emissions.

11. CONTI….
• Just as many conventional thermal power stations
generate electricity by the using og thermal energy
released from burning fossil fuels , nuclear power
plant convert the energy released from the nucleus
of an atom via nuclear fission that takes place in a
nuclear reactor.
• The heat is removed from the reactor core by a
cooling system that uses the heat to generate, steam
which drives a steam turbine connected to a
generator producing electricity.

14. INDIA’S NUCLEAR ENERGY
• NUCLEAR power is the fourth largest source of
electricity in india after thermal,hydroelectric and
renewable source of electricity.
• As of 2012 ,india has 20 nuclear reactors in operation
in six nuclear power plants,generating 4,780 MW
while seven other reactors are under construction
and are expected to generate an additional 5,300
MW.

ADVANTAGES
• Nuclear plant bring jobs and
prosperity to a country.
• Provides the world with the
most of its electricity.
• Its good for economy.
• Lots of energy is produced
from small amount of
uranium.
• Doesn’t emit carbon
dioxide.
• It renewable
DISADVANTAGES
• Disposing of the nuclear waste
is very difficult and needs to
be done after a lots of
planning by experts.
• The radioactive waste takes
years to be no longer
hazardous.
• Waste must be stored very
carefully for a long time.
• Environmental problems
through mining and processing
of uranium
