Uranium hexafluoride, sometimes called hex, is an inorganic compound with the formula U F 6. Uranium hexafluoride is a volatile, toxic white solid that is used in the process of enriching uranium , which produces fuel for nuclear reactors and nuclear weapons .
The Honeywell Uranium Hexafluoride Processing Facility, a uranium conversion facility, is located 1.9 miles (3 km) northwest of Metropolis, Illinois, United States. The plant, Honeywell Specialty Chemicals in Metropolis, Illinois, has a nominal capacity of 15,000 tU as uranium hexafluoride per year.
Depleted uranium hexafluoride (DUHF; also referred to as depleted uranium tails, depleted uranium tailings or DUF 6) is a byproduct of the processing of uranium hexafluoride into enriched uranium. [ 1 ] [ 2 ] It is one of the chemical forms of depleted uranium (up to 73-75%), along with depleted triuranium octoxide (up to 25%) and depleted ...
Gaseous diffusion uses microporous membranes to enrich uranium. Gaseous diffusion is a technology that was used to produce enriched uranium by forcing gaseous uranium hexafluoride (UF 6) through microporous membranes. This produces a slight separation (enrichment factor 1.0043) between the molecules containing uranium-235 (235 U) and uranium ...
Many molecules fit this formula. An important hexafluoride is hexafluorosilicic acid (H 2 SiF 6), which is a byproduct of the mining of phosphate rock. In the nuclear industry, uranium hexafluoride (UF 6) is an important intermediate in the purification of this element.
ConverDyn is a general partnership between American multinational firms General Atomics and Honeywell that provides uranium hexafluoride (UF 6) conversion and related services to utilities operating nuclear power plants in North America, Europe, and Asia.
Uranium hexafluoride is the feedstock used to separate uranium-235 from natural uranium. All uranium fluorides are created using uranium tetrafluoride (UF 4); UF 4 itself is prepared by hydrofluorination of uranium dioxide. [6] Reduction of UF 4 with hydrogen at 1000 °C produces uranium trifluoride (UF 3).
Enriching uranium is difficult because the isotopes are practically identical in chemistry and very similar in weight: U-235 is only 1.26% lighter than U-238 (note this applies only to uranium metal). Centrifuges need to work with a fluid rather than a solid, and this process used gaseous uranium hexafluoride.
