How much depleted uranium -- including depleted uranium hexafluoride -- is stored in the United States?
In addition to the depleted uranium stored as depleted UF6 (see the answer to the question, How much depleted uranium hexafluoride is stored in the United States?), there is approximately 30,000 MT stored in the U.S. (excluding any amount being stored as part of the strategic reserve for national defense) in other chemical forms. This inventory includes approximately 20,000 MT stored as UO3, about 3,000 MT stored as uranium metal, and about 5,000 MT stored as UF4, oxides other than UO3, process residues, and solutions. Most of this non-UF6 inventory is stored at various DOE sites with smaller quantities stored at the U.S. Department of Defense sites and at licensed commercial facilities.
