Uranium, the heaviest naturally occurring element in the periodic table, is an energy resource and basic raw material for nuclear fuel. The amount of free energy contained in nuclear fuel is millions of times the amount of energy contained in fossil fuels such as coal, oil or gas, making nuclear fission a promising source of primary heat energy.
