Which naturally occurring radioactive element is most commonly used as fuel in nuclear power plants?

Explanation

Uranium is the naturally occurring radioactive element most commonly used as fuel in nuclear power plants, where controlled nuclear fission reactions release heat that is used to generate steam and ultimately produce electricity. Naturally occurring uranium must typically undergo an industrial process called enrichment to increase the concentration of a specific isotope, uranium-235, which readily supports the fission chain reaction needed for power generation. Uranium mining and processing are subject to strict international regulations due to both radiation safety and nuclear non-proliferation concerns.
