WebDec 2, 2024 · Enriching 1,000 kilograms (kg) of natural uranium to 5% U 235 produces approximately 85 kg of enriched uranium hexafluoride (UF 6) and about 915 kg of UF 6 depleted to 0.3% U 235. As a result, the enrichment process produce tons of depleted UF 6 tails per year in the United States. These tails are then transferred to storage cylinders. WebDepleted uranium is a byproduct of the enrichment process. The amounts of uranium-234 and uranium-235 remaining in depleted uranium metal are about 0.002% and 0.2%, respectively. The effect of removing these isotopes is that depleted uranium is about 40% less radioactive than natural uranium.
