WebUranium Enrichment. Natural uranium is only 0.7% U-235, the fissionable isotope. The other 99.3% is U-238 which is not fissionable. The uranium is usually enriched to 2.5-3.5% U-235 for use in U.S. light water reactors, while the heavy water Canadian reactors typically use natural uranium. Even with the necessity of enrichment, it still takes only about 3 … WebNov 12, 2024 · Low-enriched uranium - which has a concentration of between 3% and 5% of U-235 isotopes - can be used to produce fuel for power plants.

WebSince uranium enrichment separates light isotopes from heavy isotopes, uranium enrichment also results in the enrichment of 234 U. Therefore enriched uranium also contains more isotope 234 U than natural uranium. On the other hand, enrichment tails or also depleted uranium contain much less than 234 U. In nuclear reactors, which use … WebAccording to the Associated Press, depleted uranium is what atomic scientists are left with after they’ve put the heavy metal through the enrichment process needed to produce nuclear weapons.
