WebNatural uranium (NU or U nat) refers to uranium with the same isotopic ratio as found in nature. It contains 0.711% uranium-235, 99.284% uranium-238, and a trace of uranium-234 by weight (0.0055%). Approximately 2.2% of its radioactivity comes from uranium-235, 48.6% from uranium-238, and 49.2% from uranium-234.. Natural uranium can be used … WebWeapons-grade uranium. Natural uranium is made weapons-grade through isotopic enrichment. Initially only about 0.7% of it is fissile U-235, with the rest being almost entirely uranium-238 (U-238). They are separated by their differing masses. Highly enriched uranium is considered weapons-grade when it has been enriched to about 90% U-235. inclination\\u0027s 1b

WebWhen uranium-235 is reacted by irradiation with neutrons, the uranium atoms split, releasing more neutrons, heat, and atoms with smaller atomic numbers. This process is called fission, and the heat produced can be harnessed to create electricity, similar to conventional fossil fuel power plants. Enriched uranium is a type of uranium in which the percent composition of uranium-235 (written U) has been increased through the process of isotope separation.
