Natural uranium (NU or U nat [1]) is 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.
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 ...
Uranium in the environment is a global health concern, and comes from both natural and man-made sources. Beyond naturally occurring uranium, mining, phosphates in agriculture , weapons manufacturing, and nuclear power are anthropogenic sources of uranium in the environment.
Uranium is a silvery-gray, weakly radioactive metallic chemical element.It has the chemical symbol U and atomic number 92. The most common isotopes in natural uranium are 238 U (99.274%) and 235 U (0.711%).
Further uranium-236 was produced by the decay of 244 Pu, accounting for the observed higher-than-expected abundance of thorium and lower-than-expected abundance of uranium. [67] While the natural abundance of uranium has been supplemented by the decay of extinct 242 Pu (half-life 375,000 years) and 247 Cm (half-life 16 million years), producing ...
This contains lists of countries by uranium production. The first two lists are compiled by the World Nuclear Association , and measures uranium production by tonnes mined. The last list is compiled by TradeTech, a consulting company which specializes in the nuclear fuel market.
The natural uranium can be enriched to turn into weapons-grade uranium. Ten drums totaling 2.5 tons of natural uranium have gone missing from Libya. The natural uranium can be enriched to turn ...
Uranium is produced from the Somair mine at Arlit, 63.4% owned by Orano Cycle and 36.66% by Niger state mining assets company Société du patrimoine des mines du Niger, known as SOPAMIN, and has produced nearly 68,000 tonnes (149,900,000 pounds) of uranium since operations began in 1971; and the Akouta mine at Akokan, owned by Orano Cycle (34% ...
