Uranium - Wikipedia

Uranium-234, which is a member of the uranium series (the decay chain of uranium-238), decays to lead-206 through a series of relatively short-lived isotopes. Uranium-233 is made from thorium-232 by neutron bombardment, usually in a nuclear reactor, and 233 U is also fissile.

Uranium - Element information, properties and uses ...

Naturally occurring uranium consists of 99% uranium-238 and 1% uranium-235. Uranium-235 is the only naturally occurring fissionable fuel (a fuel that can sustain a chain reaction). Uranium fuel used in nuclear reactors is enriched with uranium-235. The chain reaction is carefully controlled using neutron-absorbing materials.

NRC: Uranium Recovery (Extraction) Methods

Mar 29, 2018· Uranium recovery involves one of the following extraction processes. In a conventional uranium mine and mill, uranium ore is extracted from the Earth, typically through deep underground shafts or shallow open pits. The ore is transported to a mill, where it is crushed and undergoes a chemical process to remove the uranium.

ATSDR - Toxic Substances - Uranium

Mar 03, 2011· Uranium is a common naturally occurring and radioactive substance. It is a normal part of rocks, soil, air, and water, and it occurs in nature in the form of minerals - but never as a metal.
