it's a very small but good presentation which describes the nuclear fission and fusion.

1. PLEASE ENJOY
THIS PRESENTATION INCLUDES –
GOOD AFTERNOON
THE
NUCLEAR ENERGY
FRIENDS
PRESENTATION

2. Nuclear energy -
Two ways of production -
Nuclear fission -
Low energy neutrons are bombarded on the nucleus
of a heavy atom to get split into lighter nuclei with a
tremendous release of energy.

3. Heavy atoms
URANIUM THORIUM PLUTONUM

4. STEAM
HEAT
water
The energy thus produced is used in a nuclear reactor to
produce electricity

5. The energy produced is also used for the
purpose of destruction in an
ATOM BOMB

6. ALBERT EINSTEIN and the ATOMIC BOMB
The physicist Albert Einstein did not
directly participate in the invention
of the atomic bomb. But as we shall
see, he was instrumental in
facilitating its development
THROUGH

7. In 1905, as part of his Special Theory of Relativity, he
made the intriguing point that a large amount of
energy could be released from a small amount of
matter. This was expressed by the equation E=mc2
(energy = mass times the speed of light squared). The
atomic bomb would clearly illustrate this principle.

8. v
But bombs were not what
Einstein had in mind
when he published this
equation.

9. The theory of relativity is what used in
nuclear reactors to produce electricity
Here heat
energy is
produced
based on the
equation

10. IN NUCLEAR FISSION
+
SO THE LOST MASS IS CONVERTED INTO ENERGY
MASS > MASS
AT A RATE GOVERNED BY THE FORMULA E=MC2

11. NUCLEAR FUSION
FUSION MEANS JOINING LIGHTER
NUCLEI TO MAKE A HEAVIER NUCLEUS

13. HERE HYDROGEN ISOTOPES ARE
FUSED TO CREATE HELIUM

14. SO IN NUCLEAR FUSION TOO MASS IS
CONVERTED TO ENERGY AS THE SUM
OF THE MASSES OF THE ORIGINAL
INDIVIDUAL NUCLEI IS GREATER THAN
THE NUCLEUS THEN OBTAINED

15. CONSIDERABLE ENERGY IS NEEDED TO FORCE THE
NUCLEI TO FUSE .AND THE CONDITIONS NEEDED
FOR THIS PROCESS ARE EXTREME –
1.MILLIONS OF DEGREES OF
TEMPERATURE.
2.PASCALS OF PRESSURE
This condition is satisfied in a star

16. So nuclear fusion reactions
are the source of energy in
the sun and other stars

17. Hydrogen bomb works on this
principle
But how hydrogen bomb satisfies
the necessary conditions for fusion
to happen?

18. WORKING OF A HYDROGEN BOMB
A NUCLEAR BOMB BASED ON THE
FISSION OF URANIUM OR PLUTONIUM IS
PLACED AT THE CORE OF THE HYDROGEN
BOMB.
THIS NUCLEAR BOMB IS EMBEDDED IN A
SUBSTANCE WHICH CONTAINS
DEUTERIUM AND LITHIUM

19. WHEN THE NUCLEAR BOMB IS
DETONATED THE TEMPERATURE OF
THIS SUBSTANCE IS RAISED TO
10000000K IN A FEW MICROSECONDS
THE HIGH TEMPERATURE GENERATES
SUFFICIENT ENERGY FOR THE LIGHT
NUCLEI TO FUSE AND A DEVASTATING
AMOUNT OF ENERGY IS RELEASED

20. IN SHORT THE FUSION IN
HYDROGEN BOMB IS FUELED BY
THE FISSION.

21. Nuclear energy has long posed a dilemma
for environmentalists. As a cheap, clean
source of power that does not use fossil
fuels or add greenhouse gases to the
atmosphere, it offers an appealing
alternative to power from traditional coal-
fired plants. Yet nuclear energy is
associated with troubling environmental
issues, including the problem of radioactive
waste disposal.

22. The byproduct generated from the fission of
nuclear fuel in the form of uranium or
plutonium creates what is called nuclear
waste. This waste comes in huge variety of
extremely radioactive material with half-lives
ranging from 8 days to hundreds of thousands
of years. In other words their radioactivity
takes a really, really long time to
decay, thousands of times our human life-
times. These fission products if released to the
environment will last a long time, and the
worst part is that it is almost impossible to
decontaminate them.

23. A GOOD SOURCE OF ENERGY IS THE ONE
