Natural uranium contains about 0.72% 235 U. Depleted uranium has lower mass fractions—up to three times less—of 235 U and 234 U than natural uranium. Since 238 U has a much longer half-life than the lighter isotopes, DU is about 40% less radioactive than natural uranium.
The decommissioning of only the three uranium enrichment facilities would have an estimated cost (2004) of US$18.7 to 62 billion, with an additional US$2 to 6 billion for the dismantling of a large inventory of depleted uranium hexafluoride. A 2004 GAO report indicated the "costs will have exceeded revenues by $3.5 billion to $5.7 billion (in ...
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 ...
When fired, depleted uranium becomes ‘essentially an exotic metal dart fired at extraordinarily high speed’ ...

As a part of a $1 billion aid package, the United States announced this week that it is sending depleted anti-tank munitions to Ukraine to help Zelensky’s troops fend off Russian tanks. The ...
Portsmouth Gaseous Diffusion Plant is a facility located in Scioto Township, Pike County, Ohio, just south of Piketon, Ohio, that previously produced enriched uranium, including highly enriched weapons-grade uranium, for the United States Atomic Energy Commission (AEC), the U.S. nuclear weapons program and Navy nuclear propulsion; in later years, it produced low-enriched uranium for fuel for ...
For natural uranium fuel, fissile component starts at 0.7% 235 U concentration in natural uranium. At discharge, total fissile component is still 0.5% (0.2% 235 U, 0.3% fissile 239 Pu, 241 Pu ). Fuel is discharged not because fissile material is fully used-up, but because the neutron-absorbing fission products have built up and the fuel becomes ...
