Uranium-235 ( U or U-235) is an isotope of uranium making up about 0.72% of natural uranium. Unlike the predominant isotope uranium-238, it is fissile, i.e., it can sustain a nuclear chain reaction. It is the only fissile isotope that exists in nature as a primordial nuclide. Uranium-235 has a half-life of 703.8 million years. It was discovered in 1935 by Arthur … Web* ‘LEU IAEA’ is defined as LEU owned by the IAEA in the form of uranium hexafluoride (UF6) with a nominal enrichment of U-235 to 4.95%.
