WebAs a result, fissile materials (such as uranium-235) are a subset of fissionable materials. Uranium-235 fissions with low-energy thermal neutrons because the binding energy resulting from the absorption of a neutron is greater than the critical energy required for fission; therefore uranium-235 is a fissile material. By contrast, the binding ... 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 … See more In nuclear engineering, fissile material is material capable of sustaining a nuclear fission chain reaction. By definition, fissile material can sustain a chain reaction with neutrons of thermal energy. The predominant … See more • Fertile material • Fission product • Special nuclear material See more In general, most actinide isotopes with an odd neutron number are fissile. Most nuclear fuels have an odd atomic mass number (A … See more To be a useful fuel for nuclear fission chain reactions, the material must: • Be in the region of the binding energy curve where a … See more

Knowing Nuclear: Fissile vs Fertile vs Fissionable - YouTube
WebFissile and fertile materials. All heavy nuclides have the ability to fission when in an excited state, but only a few fission readily and consistently when struck by slow (low-energy) neutrons. Such species of atoms are called fissile. The most prominently utilized fissile nuclides in the nuclear industry are uranium-233 (233 U), uranium-235 (235 U), … Webfissile material, also called Fissionable Material, in nuclear physics, any species of atomic nucleus that can undergo the fission reaction. The principal fissile materials are … WebIn Nuclear engineering, a critical mass is the smallest amount of fissile material needed for a sustained nuclear chain reaction.
