nuclear chain reaction

[′nü·klē·ər ′chān rē‚ak·shən]
(nucleonics)
A succession of generation after generation of acts of nuclear division such that the neutrons set free in the nuclear disruptions of the n th generation split the fissile nuclei (233U,235U,239Pu) of the (n + 1)st generation. Also known as chain reaction.
