Uranium (U)							iThe energy density of uranium is much higher, at 574699 GJ/tonne for conventional nuclear reactors, and 82099829 GJ/tonne as a theoretical maximum for breeder reactors. Uranium occurs in nature as a mix of two isotopes: U235 (0.7%) and U238 (99.3%). Conventional nuclear reactors can only make use of the U235 component.
