Nuclear Material: DOE's Depleted Uranium Tails Could Be a Source of Revenue for the Government
GAO-11-752T: Published: Jun 13, 2011. Publicly Released: Jun 13, 2011.
Since the 1940s, the Department of Energy (DOE) has been processing natural uranium into enriched uranium, which has a higher concentration of the isotope uranium-235 that can be used in nuclear weapons or reactors.
