Nuclear reactors utilize chain reactions by taking the heat that is generated from the reaction,and using it to power people's homes.

The typical source that is used in a nuclear reactor is #U^235#, which absorbs a neutron to become #U^236#, which is unstable, so it splits, releasing energy in the form of heat, as well as two stable nuclei, such as barium-144 and krypton-89, which release a neutron to continue the chain as it strikes another #U^235# nucleus, causing that one to become unstable, and so on, until all the reactor''s fuel has been used up.
