How can a chain reaction be controlled
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.

WebHow is electricity produced in a nuclear power station. • The particles (or atoms) of uranium or plutonium are split into smaller particles in a nuclear reactor. (Fission) • When the … WebThe fission process may produce 2, 3, or more free neutrons that are capable of inducing further fissions and so on. This sequence of fission events is known as the fission chain reaction, and it is important in nuclear reactor physics.. The chain reaction can take place only in the proper multiplication environment and only under proper conditions.Suppose …
WebFission chain reactions and their control. The emission of several neutrons in the fission process leads to the possibility of a chain reaction if at least one of the fission neutrons … WebNuclear fission is the process in which the nucleus of an atom is split, forming nuclei of lighter atoms and neutrons. The mass of these products is less than the original mass. According to Einstein's equation E = m c 2, the small amount of missing mass is converted into a large amount of energy. A chain reaction occurs when the neutrons ...
