WebJul 18, 2009 · Natural uranium contains approximately 0.7 percent uranium-235 (the isotope essential for nuclear weapons) and 99.3 percent uranium-238. To convert natural uranium into a form that can be used in nuclear weapons, it must be "enriched" to increase the concentration of uranium-235. WebIt takes much more work to enrich uranium to 3-5% uranium-235 (typical power reactor fuel), than it does to further enrich uranium from 3-5% to 90% uranium-235 (weapons-grade material). Starting out with natural uranium, a facility with nearly 6,000 early-generation centrifuges could produce about 40 kg of weapons-grade uranium within a year. [3]
