"WebA 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 (Fig. 5.3 ). The process may be controlled (nuclear power) or uncontrolled (nuclear weapons). Figure 5.3.
