Nuclear fission & Nuclear Fusion
Nuclear fission Nuclear Fusion
Splitting of a heavy nucleus into two or Combination of two light nuclei to form a heavy
more light nuclei. nucleus.
Takes place at room temperature. Requires a very high temperature equal to 4 X
Comparatively less amount of energy is Enormous amount of energy is released.
Fission reaction can be controlled and the Fusion reaction cannot be controlled and hence
energy released can be used to generate the energy released cannot be used to generate
It is a chain reaction. It is not a chain reaction.
It leaves behind radioactive wastes. It does not leave behind any radio active wastes.
One class of nuclear weapon is a fission One class of nuclear weapon is the hydrogen
bomb, also known as an atomic bomb or bomb, which uses a fission reaction to "trigger" a
atom bomb. fusion reaction.
