Verified answer

Nuclear power is the use of nuclear reactions to produce electricity. Nuclear power can be obtained from nuclear fission, nuclear decay and nuclear fusion reactions. Presently, the vast majority of electricity from nuclear power is produced by nuclear fission of uranium and plutonium in nuclear power plants.

Explanation:

Nuclear energy is the energy that is released through nuclear reactions, specifically through the process of nuclear fission or fusion. It is harnessed by splitting the nucleus of an atom (fission) or combining two atomic nuclei (fusion). This energy is used to generate electricity in nuclear power plants.
