What is the source of Depleted Uranium? Spent fuel?
Not quite. Depleted Uranium is produced during the enrichment process.
Here is a brief extract from the article on DU from Wikipedia :
( en.wikipedia.org/wiki/...ed_uranium )
"Natural uranium metal contains about 0.71% U-235, 99.28% U-238, and about 0.0054% U-234. Depleted uranium contains only 0.2% to 0.4% U-235, the remainder having been removed and concentrated into enriched uranium through the process of isotope separation. The enrichment process does not create U-235 but merely separates the different isotopes of uranium. Therefore the process leaves large amounts of U-238 uranium as a byproduct. This byproduct is referred to as depleted uranium. For example producing 1 kg of 5% enriched uranium requires 11.8 kg of natural uranium, leaving about 10.8 kg of depleted uranium with 0.3% U-235."
