WebNov 9, 2024 · Natural uranium consists mainly of the isotope U-238 while the fissionable isotope U-235 comprises only 0.7 percent of the total. Most of the neutrons produced in a given fission process are captured by U-238 nuclei without any further production of neutrons. The escalation of the fission process thus becomes impossible. WebFissionable Isotopes While uranium-235 is the naturally occuring fissionable isotope, there are other isotopes which can be induced to fission by neutron bombardment. Plutonium-239 is also fissionable by …

According to the Ronen fissile rule, for a heavy element with 90 ≤ Z ≤ 100, its isotopes with 2 × Z − N = 43 ± 2, with few exceptions, are fissile (where N = number of neutrons and Z = number of protons). The term fissile is distinct from fissionable. A nuclide capable of undergoing fission (even with a low probability) after capturing a neutron of high or low energy is referred to as fissionable.
