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 .
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 ...
4 January 1986: an overloaded tank at Sequoyah Fuels Corporation ruptured and released 14.5 tons of uranium hexafluoride gas (UF6), causing the death of a worker, the hospitalization of 37 other workers, and approximately 100 downwinders. [87] [88] [89]
It said the worker died from a "mechanical injury" caused by a breach in a container of uranium hexafluoride, a chemical compound used in uranium enrichment. Cylinder ruptures in Russian uranium ...
Depleted uranium was originally stored as an unusable waste product (uranium hexafluoride) in the hope that improved enrichment processes could extract additional quantities of the fissionable 235 U isotope. This re-enrichment recovery of the residual uranium-235 is now in practice in some parts of the world; e.g. in 1996 over 6000 metric ...
The mode of enrichment was gaseous diffusion of uranium hexafluoride to separate the lighter fissile isotope U-235 from the heavier non-fissile isotope U-238. The Paducah plant produced low-enriched uranium which was further refined at Portsmouth and the K-25 plant at Oak Ridge, Tennessee. From the 1960s the Paducah plant was dedicated to ...

Uranium hexafluoride (UF 6) was the only known compound of uranium sufficiently volatile to be used in the gaseous diffusion process. [17] Before this could be done, the Special Alloyed Materials (SAM) Laboratories at Columbia University and the Kellex Corporation had to overcome formidable difficulties to develop a suitable barrier.
