WebFissionable material consists of isotopes that are capable of undergoing nuclear fission after capturing either fast neutron (high energy neutron – let say >1 MeV) or thermal neutron (low energy neutron – let say 0.025 eV). Typical fissionable materials: 238U, 240Pu, but also 235U, 233U, 239Pu, 241Pu Nuclear fission can occur without neutron bombardment as a type of radioactive decay. This type of fission (called spontaneous fission) is rare except in a few heavy isotopes. In engineered nuclear devices, essentially all nuclear fission occurs as a "nuclear reaction" — a bombardment-driven process that results from the collis… ear suction with cameraWebOct 27, 2024 · Material that can sustain a nuclear fission chain reaction is said to be fissile or fissionable.

The other fissile material is uranium-235. Plutonium-239 is virtually nonexistent in nature.

WebMany heavy atomic nuclei are capable of fissioning, but only a fraction of these are fissile—that is, fissionable not only by fast (highly energetic) neutrons but also by slow neutrons. The continuing process whereby neutrons emitted by fissioning nuclei induce fissions in other fissile or fissionable nuclei is called a fission chain reaction. WebSep 9, 2024 · Definitions.
