WebMar 9, 2024 · A reaction that initiates its own repetition. In a fission chain reaction, a fissionable nucleus absorbs a neutron and fissions spontaneously, releasing additional neutrons. These, in turn, can be absorbed by other fissionable nuclei, releasing still more neutrons. A fission chain reaction is self-sustaining when the number of neutrons … WebThe necessary condition for a stable, self-sustained fission chain reaction in a multiplying system (in a nuclear reactor) is that exactly every fission initiates another fission. The minimum condition is for each nucleus undergoing fission to produce, on average, at least one neutron that causes fission of another nucleus.
WebSep 12, 2024 · Figure \(\PageIndex{4}\): In a U-235 fission chain reaction, the fission of the m nucleus produces high-energy neutrons that go on to split more nuclei. The energy released in this process can be used to produce electricity. View a simulation on nuclear fission to start a chain reaction, or introduce nonradioactive isotopes to prevent one ... WebNov 29, 2024 · The success of the sustained fission chain reaction at Chicago led to the first nuclear bomb test, at Alamogordo, N.M., on July 16, 1945 (shown), and the bombs that ended World War II.
WebFission Chain Reaction Since neutrons are necessary to cause the fission event, and since each fission releases neutrons, there is the potential to set up a self-sustaining chain reaction. For this to occur, there must be sufficient material capable ... If the conditions in the core allow, the chain reaction will reach a state of being self ...

In nuclear physics, a nuclear chain reaction occurs when one single nuclear reaction causes an average of one or more subsequent nuclear reactions, thus leading to the possibility of a self-propagating series of these reactions. The specific nuclear reaction may be the fission of heavy isotopes (e.g., uranium-235, … See more Chemical chain reactions were first proposed by German chemist Max Bodenstein in 1913, and were reasonably well understood before nuclear chain reactions were proposed. It was understood that … See more Prompt neutron lifetime The prompt neutron lifetime, l, is the average time between the emission of neutrons and either their absorption in the system or their escape from the system. The neutrons that occur directly from fission are called " See more Chain reactions naturally give rise to reaction rates that grow (or shrink) exponentially, whereas a nuclear power reactor needs to be able to hold the reaction rate … See more • Nuclear Chain Reaction Animation • Annotated bibliography on nuclear chain reactions from the Alsos Digital Library See more Fission chain reactions occur because of interactions between neutrons and fissile isotopes (such as U).
