Nuclear energy is the energy released during a nuclear reaction as a result of fission or fusion It is also called atomic energy.


Nuclear binding energy is the energy required to break apart, split, or break down, the nucleus of the atom into its component parts (nucleons), i.e. neutrons and protons. 

  • If the binding energy for the products is higher when light nuclei fuse, or when heavy nuclei split, either of these processes will result in a release of the "extra" binding energy, and this energy is referred to as nuclear energy. It is also loosely called nuclear power
Nuclear Power is the use of sustained nuclear fission to generate heat and do useful work. 
  • Nuclear Electric Plants, Nuclear Ships and Submarines use controlled nuclear energy to heat water and produce steam, while in space, nuclear energy decays naturally in a radioisotope thermo-electric generator. 
  • Scientists are experimenting with fusion energy for future generation, but these experiments do not currently generate useful energy.

Nuclear power provides about 6% of the world's energy and 13–14% of the world's electricity, with the U.S., France, and Japan together accounting for about 50% of nuclear generated electricity.
Also, more than 150 naval vessels using nuclear propulsion have been built.
