Web19 mrt. 2024 · A nuclear fission reaction takes place when the atoms of an unstable element are bombarded with neutrons, splitting the nucleus of each atom into smaller parts. If the split of each nucleus releases several high-speed neutrons that can then split more of the element's nuclei, a chain reaction takes place.
