What Is Nuclear Energy?
• Power plants use heat to produce electricity. Nuclear energy
produces electricity from heat through a process called fission.
Nuclear power plants use the heat produced by fission of certain
atoms.

7. Fission occurs in
the reactor vessel.
Heat is produced.
The heat is used to heat
water to create steam
The steam is used to
turn the turbine in the
generator to produce
electricity
The steam is cooled in
the condenser to
return to the liquid
phase.
How a Nuclear Reactor works?

8. • Pressurized Water Reactor keeps water under pressure so that
it heats up but doesn’t boil. Water from the reactor and water
that is turned into steam are in separate pipes.

Nuclear Reactors

9. • Boiling Water Reactor uses the heat from fission to heat water until
it boils. The water from the reactor and that water that is turned into
steam are the same.

14. Advantages
Nuclear power generation does emit relatively low amounts of
carbon dioxide (CO2). The emissions of green house gases and
therefore the contribution of nuclear power plants to global
warming is therefore relatively little.
This technology is readily available, it does not have to be developed
first.
It is possible to generate a high amount of electrical energy in one
single plant.

15. Disadvantages
The problem of radioactive waste is still an unsolved one.
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.

16. Nuclear Plant Future
The countries of the world are each planning their own.
Course of nuclear plant development or decline.
Nuclear power is competitive with natural gas.
It is non - polluting.
It does not contribute to global warming.
Obtaining the fuel only takes 5% of the energy output
Plant licenses have been extended from 20 years to an additional 20
years.
Disposal of high level radioactive waste still being studied, but
scientists believe deep burial would work.Because they are have large
electrical output, their cost at $2 billion is hard to obtain and guarantee
with banks.
