Share this question with your friends. The U 3 O 8 concentrate typically contains more than 80% uranium. The original ore, by comparison, may contain as little as 0.1% uranium. In the United States, uranium ores contain from 0.05–0.3% of the uranium oxide U 3 O 8; the uranium in the ore is about 99.3% nonfissionable U-238 with only 0.7% fissionable U-235. a) High energy (fast) neutrons alone All uranium isotopes present in natural uranium are radioactive and fissionable, and 235 U is fissile (will support a neutron-mediated chain reaction). Uranium enrichment is a process that is necessary to create an effective nuclear fuel out of mined uranium by increasing the percentage of uranium-235 which undergoes fission with thermal neutrons.Although many reactors require enriched uranium fuel, the Canadian-designed CANDU, the British Magnox reactor and the proposed Molten salt reactor can use natural uranium as their fuel.
