Web23 mrt. 2015 · For example, if an enrichment facility processes 1,000 kilograms (kg) of natural uranium to raise the U 235 concentration from 0.7 percent to 5 percent, the facility would produce 85 kg of enriched uranium and 915 kg of depleted uranium. The amount of U 235 in the bulk of the material decreases, or is depleted, to a concentration of 0.3 … WebThe process used to increase the amount of uranium-235 relative to uranium-238 is known as uranium enrichment. U.S. civilian power plants typically use 3 to 5 percent uranium-235. Weapons use “highly enriched uranium” (HEU) with over 90 percent uranium-235. Some research reactors and all U.S. naval reactors also use HEU.
WebIn order to make an explosion, fission weapons do not require uranium or plutonium that is pure in the isotopes uranium-235 and plutonium-239. Most of the uranium used in current nuclear weapons is approximately 93.5 percent enriched uranium-235. Nuclear weapons typically contain 93 percent or more plutonium-239, ...
