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 is a chemical element with the symbol U and atomic number 92. It is a silvery-grey metal in the actinide series of the periodic table. A uranium atom has 92 protons and 92 electrons, of which 6 are valence electrons. Uranium radioactively decays, usually by emitting an alpha particle.
Sample of uranium ore. Uranium ore deposits are economically recoverable concentrations of uranium within Earth's crust. Uranium is one of the most common elements in Earth's crust, being 40 times more common than silver and 500 times more common than gold. [1] It can be found almost everywhere in rock, soil, rivers, and oceans. [2]
Uranium is a naturally occurring element found at low levels within all rock, soil, and water. This is the highest-numbered element to be found naturally in significant quantities on Earth. According to the United Nations Scientific Committee on the Effects of Atomic Radiation the normal concentration of uranium in soil is 300 μg/kg to 11.7 mg/kg.
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.
Iran said Wednesday it gave new details to the United Nations about two sites near Tehran that inspectors say bore traces of manmade uranium, part of a wider probe as tensions remain high over the ...
Uranium occurs at concentrations of 50 to 200 parts per million (ppm) in phosphate-laden earth or phosphate rock. As uranium prices increase, there has been interest in extraction of uranium from phosphate rock, which is normally used as the basis of phosphate fertilizers. [86] There are 22 million tons of uranium in phosphate deposits.
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. Natural uranium can be used to fuel ...
