What is Depleted Uranium Hexafluoride?
Depleted uranium hexafluoride (DUF6) is generated in large quantities through the uranium enrichment process. The term “Depleted” indicates that most of the more useful U-235 isotope of uranium has been removed through an enrichment process. DUF6 has been generated, transported, stored, and managed safely in the U.S. for several decades. However, it is a fluorine compound that can react with water or ethanol to produce toxic fumes of hydrofluoric acid. To protect against accidental release the DUF6 is kept in sturdy cylinders before and after enrichment, as well as during storage and transportation.
