WebUranium is a common, naturally occurring element, present in low amounts in rocks, soil, air, surface water and groundwater. Uranium is naturally radioactive, like many other naturally occurring radioactive elements in nature. Natural uranium exists as a mixture of three types, or isotopes, called U-234 ( 234 U), U-235 ( 235 U), and U-238 ( 238 U). 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.
Natural uranium (NU or Unat ) refers to uranium with the same isotopic ratio as found in nature. It contains 0.711% uranium-235, 99.284% uranium-238, and a trace of uranium-234 by weight (0.0055%). Approximately 2.2% of its radioactivity comes from uranium-235, 48.6% from uranium-238, and 49.2% from uranium-234. Natural uranium can be used to fuel both low- and high-power nuclear reactors.
