Fertile material is a term used to describe nuclides which generally themselves do not undergo induced fission (fissionable by thermal neutrons) but from which fissile material is generated by neutron absorption and subsequent nuclei conversions. Fertile materials that can be converted into a fissile material by irradiation in a reactor are: thorium-232 which can be converted into fissionable uranium-233, and uranium-238 which can be converted into fissionable plutonium-239. ... In general fission is a splitting or breaking up into parts. ... Properties In physics, the neutron is a subatomic particle with no net electric charge and a mass of 940 MeV/c² (1. ... This article or section should include material from Fissile material In nuclear engineering, a fissile material is one that is capable of sustaining a chain reaction of nuclear fission. ... This article or section should be merged with Fissile Fissile material is composed of atoms that can undergo nuclear fission and sustain a fission chain reaction. ... Thorium 232 is a naturally occurring isotope of thorium. ... Uranium-233, is a uranium isotope, which is created by irradiating thorium-232 with neutrons, it has a half-life of 160,000 years. ...

A Fast breeder reactor, a reactor with little or no neutron moderator and hence utilising fast neutrons, can be configured to produce more fissile material than it consumes, using fertile material in a blanket around the core, or contained in special fuel rods. The fast breeder or fast breeder reactor (FBR) is a type of fast neutron reactor that produces more fissile material than it consumes. ... In nuclear engineering, a neutron moderator is a medium which reduces the velocity of fast neutrons, thereby turning them into thermal neutrons capable of sustaining a nuclear chain reaction. ...
