Web28 mrt. 2024 · Depleted uranium, or DU, as it is known, is a byproduct of the nuclear enrichment process used to produce nuclear fuel and nuclear weapons. The uranium that remains after the enrichment process is depleted and around 40% less radioactive than naturally occurring uranium and is used to make tank shells because it's so hard. WebSeveral enrichment techniques have been developed, though only two of these methods are used on a large scale; these are gaseous diffusion and gas centrifuging. In gaseous diffusion, natural uranium in the form of uranium hexafluoride gas (UF 6), a product of chemical conversion, is encouraged (through a mechanical process) to seep through a …
