World uranium reserves in 2010. Uranium reserves are reserves of recoverable uranium, regardless of isotope, based on a set market price. The list given here is based on Uranium 2020: Resources, Production and Demand, a joint report by the OECD Nuclear Energy Agency and the International Atomic Energy Agency. [1] Figures are given in metric ...
Depleted uranium (DU) is a byproduct of uranium enrichment that is used for defensive armor plating and armor-piercing projectiles. Uranium contamination has been found at testing sites in the UK, in Kazakhstan, and in several countries as a result of DU munitions used in the Gulf War and the Yugoslav wars. [1]
Natural uranium contains about 0.72% 235 U. Depleted uranium has lower mass fractions—up to three times less—of 235 U and 234 U than natural uranium. Since 238 U has a much longer half-life than the lighter isotopes, DU is about 40% less radioactive than natural uranium.
According to Michigan State University, the use of uranium was deregulated in 1958, and production of uranium glass picked up again—except this time, only depleted uranium was used.
Historically, uranium has been mined in countries willing to export, including Australia and Canada. [2] [3] However, countries now responsible for more than 50% of the world’s uranium production include Kazakhstan, Namibia, Niger, and Uzbekistan. [4] Uranium from mining is used almost entirely as fuel for nuclear power plants.

[14] [15] In 1950, a uranium processing plant was said to be under construction near the mine. [10] At the time, Shinkolobwe was believed to contain roughly half of the world's known reserves of uranium. [16] In 1947, the US received 1,440 tons of uranium concentrates from the Belgian Congo, 2,792 in 1951, and 1,600 in 1953.
When fired, depleted uranium becomes ‘essentially an exotic metal dart fired at extraordinarily high speed’
