What is nuclear energy?

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

Types of Nuclear energy

• Nuclear Fission
• Nuclear Fusion

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.

• 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.
