Isotope separation is the process of concentrating specific isotopes of a chemical element by removing other isotopes. Uranium is a chemical element with symbol U and atomic number 92. Uranium has the highest atomic weight of the primordially occurring elements. It occurs naturally in low concentrations of a few parts per million in soil, rock and water, and is commercially extracted from uranium-bearing minerals such as uraninite. An ensuing arms race during the Cold War between the United States and the Soviet Union produced tens of thousands of nuclear weapons that used uranium metal and uranium-derived plutonium-239.
