Fissionable uranium isotope
Did you know?
WebNatural uranium consists of two primary isotopes with mass numbers of 235 and 238. Of the two, only uranium-235 is capable of the sustained fission chain-reaction necessary for an atomic bomb. WebThe remaining 99.28% is mostly the 238U isotope which is a fissionable isotope, but is not a fissile isotope. Most reactors require uranium to be enriched from 0.7% to higher concentrations. The process of increasing the concentration of one isotope relative to another is called “enrichment.”
WebMar 9, 2024 · Fissionable material A nuclide that is capable of undergoing fission after capturing either high-energy (fast) neutrons or low-energy thermal (slow) neutrons. Although formerly used as a synonym for fissile material, fissionable materials also include those (such as uranium-238) that can be fissioned only with high-energy neutrons. WebMar 22, 2024 · The two most common isotopes of uranium are U-238 and U-235. About 99.3% of uranium is of the U-238 variety, this form is not fissionable and will not work in a nuclear weapon or reaction. The remaining .7% is U-235 which is fissionable but first had to be separated from U-238. This separation process is called enrichment. During World …
