The History of Nuclear power, its advantage and disadvantages. And the main question is that is it the renewable energy?

1. Nuclear Energy

2. General Information
Atoms look like our solar system with their
construction. At the center of the atom is
the nucleus and electrons orbiting around
it. Most of the mass of each atom is
concentrated in nucleus and the rest of the
mass is in the cloud of electrons. Protons
and neutrons are subatomic particles that
hold together by a strong force in the
nucleus.

4. History
▪ Manhattan Project
The Manhattan Project was a research and
development project that produced the first
nuclear weapons duringWorldWar II. It was
led by the United States with the support of
the United Kingdom and Canada.

6. Mining and Precessing of Nuclear Fuel
Uranium mining is the process of
extraction of uranium ore from
the ground.

7. Mining and Precessing of Nuclear Fuel
The worldwide production of uranium
in 2012 amounted to 58,394
tonnes. Kazakhstan,Canada,
and Australia are the top three
producers and together account for
64% of world uranium production.
Other major producers are the United
States, South Africa, Namibia, Brazil,
Niger and Russia.

8. Types of Nuclear Reactors
PressurizedWater Reactors

9. Types of Nuclear Reactors
Boiling Water Reactors

10. How does a Nuclear Reactor work?
▪ 3.5 % enriched
uranium rods and
demineralised water
is used in a nuclear
reactors. Uranium
rods must stay
upright position in the
water.

11. Uranium Rods
▪ Uranium hexafluoride is sent to
fuel production refineries and
there we obtain uranium dioxide
powder from it.Then this
powder is processing into small
fuel pellets .As a next step this
pellets are heated and become a
hard ceramic material.This
strong material in turn is placed
thin tubes and we get uranium
rods.

12. Difference Between Nuclear Fission
and Fusion
Fission is the energetic
splitting of large atoms such as
Uranium or Plutonium into two
smaller atoms, called fission
products.To split an atom, you
have to bombard it with a
neutron. Several neutrons are
also released which can go on
to split other nearby atoms,
producing a nuclear chain
reaction of sustained energy
release.

13. Difference Between Nuclear Fission
and Fusion
Fusion is the combining of
two small atoms such as
Hydrogen or Helium to
produce heavier atoms and
energy.

14. Advantages of Using Nuclear Energy
Material Energy Density (MJ/kg) 100W light bulb time (1kg)
Wood 10 1.2 days
Ethanol 26.8 3.1 days
Coal 32.5 3.8 days
Crude oil 41.9 4.8 days
Diesel 45.8 5.3 days
Natural Uranium (LWR) 5.7x105 182 years
Reactor Grade Uranium (LWR) 3.7x106 1,171 years
Natural Uranium (breeder) 8.1x107 25,700 years
Thorium (breeder) 7.9x107 25,300 years

15. Advantages of Using Nuclear Energy
1. Lower Greenhouse Emissons
As per the reports lately, it has
been calculated the emission of
the greenhouse gases have
reduced for nearly half due to
use of nuclear power.

16. Advantages of Using Nuclear Energy
2. Powerfull and Efficient
Advancement in technologies has made it more viable
option than others.This is one the reason that many
countries are putting huge investments in nuclear
power.

17. Advantages of Using Nuclear Energy
3. Reliable
Nuclear energy can be produced from nuclear power
plants even in the cases of rough weather conditions
and 24/7.

18. Advantages of Using Nuclear Energy
4. Cheap Electricity
The cost of uranium which is
used as a fuel in generating
electricity is quite low. Also,
set up costs of nuclear
power plants is relatively
high while running cost is
low.The average life of
nuclear reactor range from
4.-60 years depending upon
its usage.

19. Advantages of Using Nuclear Energy
5. Low Fuel Cost
The main reason behind the low
fuel cost is that it requires little
amount of uranium to produce
energy.When a nuclear reaction
happens, it releases million
times more energy as compared
to traditional sources of energy.

20. Advantages of Using Nuclear Energy
6. Supply
Nuclear energy is widely
available, has huge reserves
and expected to last for
another 100 years while coal,
oil and natural gas are limited
and are expected to vanish
soon.

21. Advantages of Using Nuclear Energy
7. Easy toTransport
Production of nuclear energy needs
very less amount of raw material.
This means that only about 28 gram
of uranium releases as much energy
as produced from 100 metric tons of
coal. Since it’s required in small
quantities, transportation of fuel is
much easier than fossil fuels.

22. Disadvantages of using Nuclear Energy
1. Radioactive Waste
When the uranium has
finished splitting, the
resulting radioactive
byproducts need to be
removed.

23. Disadvantages of using Nuclear Energy
2. Raw Material
Uranium is used in the process of
fission because it's a naturally
unstable element.This means that
special precautions must be taken
during the mining, transporting
and storing of the uranium, as well
as the storing of any waste product
to prevent it from giving off
harmful levels of radiation.

24. Disadvantages of using Nuclear Energy
3. Nuclear Accidents
Serious nuclear accidents have
been few and far between—but
their stories will help prevent future
catastrophes.

25. Disadvantages of using Nuclear Energy
4. Fuel Availability
Unlike fossil fuels which are
available to most of the
countries, uranium is very rare
resource and exist in only few
of the countries.

26. Disadvantages of using Nuclear Energy
5. Non-renewable Energy
Nuclear energy is an alternative
energy but not a renewable energy
as Uranium is a non-renewable
source and its supplies are limited.

27. Disadvantages of using Nuclear Energy
6. HotTarget for Militants
Nuclear energy has immense
power.Today, nuclear energy
is used to make weapons. If
these weapons go into the
wrong hands, that could be
the end of this world. Nuclear
power plants are prime
target for terrorism activities.

28. Alternative “Raw” - Thorium
Thorium is easier to find, creates
less radiation, and creates less
waste than Uranium for nuclear
power.

29. Alternative “Raw” - Thorium

30. Is Nuclear Energy renewable source or
not?
By definition, nuclear energy is not
a renewable energy source. As we
mentioned above, there is a limited
amount of fuel for nuclear power
available. On the other hand, you
could argue that nuclear energy is
potentially sustainable by the use of
breeder reactors and fusion
reactors. Nuclear fusion is the holy
grail of harnessing energy.
