Detailed explanation-1: -nuclear fission, subdivision of a heavy atomic nucleus, such as that of uranium or plutonium, into two fragments of roughly equal mass. The process is accompanied by the release of a large amount of energy. In nuclear fission the nucleus of an atom breaks up into two lighter nuclei.
Detailed explanation-2: -During nuclear fission, a neutron collides with a uranium atom and splits it, releasing a large amount of energy in the form of heat and radiation. More neutrons are also released when a uranium atom splits. These neutrons continue to collide with other uranium atoms, and the process repeats itself over and over again.
Detailed explanation-3: -The energy released in fission is mostly in the form of kinetic energy and is absorbed by fission products. The fission products are neutrons and gamma radiation. As the neutrons collide, the kinetic energy is transformed into heat energy.
