Web2 hours ago · When minerals form out of magma or lava, they often contain traces of radioactive material, such as uranium. Over time, those radioactive elements decay, … WebUranium and Depleted Uranium. (Updated November 2024) The basic fuel for a nuclear power reactor is uranium – a heavy metal able to release abundant concentrated energy. Uranium occurs naturally in the Earth's crust and is mildly radioactive. It is the only element with a naturally-occurring fissile isotope.
