The largest uranium producer in the United States is ramping up work just south of Grand Canyon National Park on a long-contested project that largely has sat dormant since the 1980s ...
Uranium's concentration in the Earth's crust is (depending on the reference) 2 to 4 parts per million, [11] [22] or about 40 times as abundant as silver. [17] The Earth's crust from the surface to 25 km (15 mi) down is calculated to contain 10 17 kg (2 × 10 17 lb) of uranium while the oceans may contain 10 13 kg (2 × 10 13 lb). [11]
Uranium fuel used in today's reactors is enriched to about 5%. Big Tech companies such as Amazon have plans to build new reactors to serve power-hungry data centers.
96% of the mass is the remaining uranium: most of the original 238 U and a little 235 U. Usually 235 U would be less than 0.8% of the mass along with 0.4% 236 U. Reprocessed uranium will contain 236 U, which is not found in nature; this is one isotope that can be used as a fingerprint for spent reactor fuel.
The uranium for conventional reactors is enriched up to 5% and HALEU is uranium enriched between 5-20%. Highly enriched uranium is anything more than 20% and is used in weapons or naval submarines.
Uranium-235 (235 U or U-235) is an isotope of uranium making up about 0.72% of natural uranium. Unlike the predominant isotope uranium-238, it is fissile, i.e., it can sustain a nuclear chain reaction. It is the only fissile isotope that exists in nature as a primordial nuclide. Uranium-235 has a half-life of 703.8 million years.
Iran had previously slowed down the rate at which it was enriching uranium to 60% purity. Uranium enriched at 60% purity is just a short, technical step away from weapons-grade levels of 90%.
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 ...
