Urals crude is Russia's primary export crude oil blend, a medium sour grade named after the Ural Mountains and priced in world markets at a differential to Brent.
Uranium carbide
Uranium carbide, best known as uranium monocarbide (UC), is a ceramic compound of uranium and carbon studied as nuclear reactor fuel for its high uranium density and thermal conductivity.
Uranium dioxide
Uranium dioxide (UO₂) is a black ceramic oxide of uranium, found naturally in the mineral uraninite, that serves as the standard fuel for most commercial nuclear power reactors.
Uranium Energy Corp

Uranium enrichment
Uranium enrichment is the physical process of increasing the proportion of the fissile isotope uranium-235 in uranium, most often to make fuel for nuclear reactors and weapons.
Uranium extraction from seawater
Uranium extraction from seawater (UES) recovers dissolved uranium from ocean water, which holds about 4.5 billion tons, mostly by adsorption onto amidoxime adsorbents, though costs still exceed terrestrial mining.
Uranium mill tailings
Uranium mill tailings are the sandy waste left after a uranium mill extracts uranium from ore, containing radium-226 and thorium-230 and regulated under the 1978 UMTRCA.
Uranium Mill Tailings Radiation Control Act
The Uranium Mill Tailings Radiation Control Act of 1978 is a United States federal law that established programs to stabilize and regulate uranium mill tailings at active and inactive mill sites.
Uranium Mill Tailings Remedial Action program
The Uranium Mill Tailings Remedial Action (UMTRA) program is a U.S. Department of Energy program that cleaned up abandoned uranium mill tailings sites under the 1978 UMTRCA.
Uranium molybdenum alloy
Uranium molybdenum alloy (U-Mo) is a metallic nuclear fuel, about 7 to 10 percent molybdenum, developed for converting research and test reactors to low-enriched uranium.
Uranium One
Uranium One is a Canadian-based uranium mining company that came under full ownership of Russia's Rosatom by 2013, after a 2010 deal approved by CFIUS.
Uranium Royalty Corp
Uranium Royalty Corp is a royalty and streaming company that holds uranium interests, including royalties on Cameco's McArthur River and Cigar Lake mines, without operating mines itself.
Uranium silicide
Uranium silicide, mainly the compound U3Si2, is a high-density nuclear fuel used in aluminum-matrix research reactor plates and tested as an accident tolerant light water reactor fuel.
Uranium-233
Uranium-233 is a fissile artificial isotope of uranium with a half-life of about 160,000 years, bred from natural thorium-232 by neutron capture and used as a nuclear reactor fuel.
Uranium-plutonium-zirconium metal fuel
Uranium-plutonium-zirconium metal fuel (U-Pu-Zr) is a ternary metallic alloy nuclear fuel, developed at Argonne National Laboratory as the driver fuel for the Integral Fast Reactor.
Uranium-zirconium alloy
Uranium-zirconium alloy, or U-Zr, is a metallic nuclear fuel, usually uranium with 10 weight percent zirconium, valued for high thermal conductivity and use in sodium-cooled fast reactors like EBR-II.
Uranium-zirconium hydride
Uranium-zirconium hydride (UZrH) is a nuclear fuel combining uranium metal and a zirconium hydride moderator, developed by General Atomics in 1957 for the TRIGA research reactors.

Urdaneta Oeste oil field
Urdaneta Oeste, also called Urdaneta West, is a heavy-oil field on the western margin of Lake Maracaibo in northern Venezuela, discovered in 1955 with reserves of about 1.5 billion barrels.
Urea electrolysis
Urea electrolysis is an electrochemical process in which urea is oxidized at the anode rather than water, lowering the voltage needed for hydrogen production from the 1.23 V of water electrolysis to 0.37 V.
