Nuclear Fission

Nuclear fission is a nuclear reaction in which the nucleus of an atom splits into smaller parts. This process releases a large amount of energy and is the principle behind nuclear power plants and nuclear weapons.

Process of Nuclear Fission

During nuclear fission, a heavy atomic nucleus, such as that of uranium-235 or plutonium-239, absorbs a neutron and becomes unstable. The nucleus then splits into two or more smaller nuclei, along with the release of additional neutrons and a large amount of energy in the form of gamma rays and kinetic energy.

Applications of Nuclear Fission

Nuclear fission is used in nuclear power plants to generate electricity. The heat produced during fission is used to produce steam, which drives a turbine to generate electricity. Additionally, nuclear fission has been used in the development of nuclear weapons.
