Fissile material - Wikipedia In nuclear engineering, fissile material is material that can undergo nuclear fission when struck by a neutron of low energy [1] A self-sustaining thermal chain reaction can only be achieved with fissile material
Fissile material | Uranium-235, Plutonium-239 Nuclear Reactors . . . fissile material, in nuclear physics, any species of atomic nucleus that can undergo the fission reaction The principal fissile materials are uranium-235 (0 7 percent of naturally occurring uranium), plutonium-239, and uranium-233, the last two being artificially produced from the fertile materials uranium-238 and thorium-232, respectively
FISSILE Definition Meaning - Merriam-Webster Fissile (which can be traced back to the Latin verb findere, meaning "to split") was used in reference to things like rocks When we hear about fissile materials today, the reference is usually to nuclear fission: the splitting of an atomic nucleus that releases a huge amount of energy
Fissile material | Nuclear Regulatory Commission - NRC A nuclide that is capable of undergoing fission after capturing low-energy thermal (slow) neutrons Although sometimes used as a synonym for fissionable material, this term has acquired its more-restrictive interpretation with the limitation that the nuclide must be fissionable by thermal neutrons
What Is Fissile Material and How Does It Work? - ScienceInsights Fissile material is any substance whose atoms can be split by slow-moving (low-energy) neutrons, releasing enough additional neutrons to keep the splitting process going in a self-sustaining chain reaction The three primary fissile materials are uranium-235, plutonium-239, and uranium-233
What does Fissile mean? - Definitions. net Fissile refers to any material that is capable of undergoing nuclear fission, the process of splitting atomic nuclei, when struck by a neutron This term is commonly used in nuclear physics and nuclear engineering, especially in the context of nuclear reactors and nuclear weapons
Fissile - Energy Education The property which determines whether or not an isotope is fissile or just fertile is known as the fission cross section When a slow or thermal neutron interacts with an atom, it can be scattered or absorbed
