2
What is nuclear energy?
  • Nuclear energy is released by the splitting
    (fission) or merging together (fusion) of the
    nuclei of atom

3
Types of Nuclear energy
  • Nuclear Fission
  • Nuclear Fusion

4
Nuclear Fission
  • An induced fission reaction. A slow-moving
    neutron is absorbed by the nucleus of a
    uranium-235 atom, which in turn splits into
    fast-moving lighter elements (fission products)
    and three free neutrons.

5
  • Nuclear fission produces energy for nuclear power
    and to drive the explosion of nuclear weapons.
    Both uses are made possible because certain
    substances called nuclear fuels undergo fission
    when struck by free neutrons and in turn generate
    neutrons when they break apart

6
  • The amount of free energy contained in nuclear
    fuel is millions of times the amount of free
    energy contained in a similar mass of chemical
    fuel such as gasoline, making nuclear fission a
    very tempting source of energy

Nuclear Fusion
  • Fusion power is the power generated by nuclear
    fusion reactions. In this kind of reaction, two
    light atomic nuclei fuse together to form a
    heavier nucleus and in doing so, release a large
    amount of energy.
  • In a hydrogen bomb, two isotopes of hydrogen,
    deuterium and tritium are fused to form a nucleus
    of helium and a neutron. This fusion releases
    17.6 MeV of energy. Unlike nuclear fission, there
    is no limit on the amount of the fusion that can
    occur.
