WebNuclear Chain Reactions. A chain reaction refers to a process in which neutrons released in fission produce an additional fission in at least one further nucleus. This nucleus in turn produces neutrons, and the process repeats. The process may be controlled (nuclear power) or uncontrolled (nuclear weapons). WebFISSION meaning: 1 : a process in which the nucleus of a heavy atom is split apart; 2 : a kind of reproduction in which a cell or body divides into two or more parts and each …
