lõhustumisahel
Lõhustumisahel, also known as a fission chain reaction, is a self-sustaining nuclear reaction where one nuclear fission event triggers subsequent fission events. This process typically involves heavy atomic nuclei, such as uranium-235 or plutonium-239, which are capable of undergoing fission when struck by a neutron. When a fissile nucleus absorbs a neutron, it becomes unstable and splits into two or more lighter nuclei, releasing a significant amount of energy and several additional neutrons. These newly released neutrons can then go on to strike other fissile nuclei, initiating further fission events.
For a chain reaction to be sustained, on average, at least one neutron from each fission event
Nuclear reactors utilize controlled chain reactions to generate heat, which is then used to produce electricity.
