Nuclear Chain Reactions

A nuclear chain reaction occurs when an initial event, such as the splitting of an atomic nucleus (nuclear fission), releases energy and additional neutrons. These neutrons can then collide with other nearby nuclei, causing them to split as well. This process can rapidly multiply, producing a large amount of energy. It’s the principle behind both nuclear power plants, which control the reaction to generate electricity, and nuclear weapons, which release energy in an uncontrolled explosion. The key is maintaining a delicate balance to ensure the reaction is sustained or terminated as needed.
