Power plants produce energy by the process of nuclear fusion fission

Power plants produce energy by the process of nuclear fission.

Explanation:

Fission : it is a type of nuclear reaction in which larger unstable nucleus splits into smaller stable nuclei with release in large amount of energy.

The energy released is then used to produce steam which further used to run turbines to produce electrical energy.

Generally, uranium isotopes is used in power plants to produce an energy.
