The history and the development of atomic energy can be explained by the following points:
The science of atomic radiation, atomic change and nuclear fission was developed from 1895 to 1945,
Over 1939-45, most development was focused on the atomic bomb.
From 1945 attention was given to use atomic energy in controlled fashion for naval propulsion and for making electric energy.
- Since 1956 the prime focus of atomic energy is on the technological evolution of reliable nuclear power plants.
