The energy ''density'' of uranium is 574699 GJ/tonne for conventional nuclear reactors, and 82099829 GJ/tonne as a theoretical maximum for [[breeder reactors]].<br /><br />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.}} | ||
