WebOperators carefully control the chain reaction in the nuclear reactor in several ways. The fuel type and how the reactor core is arranged changes depending on how much nuclear fission occurs. The use of a moderator (light water, heavy water or graphite) slows down neutrons. At Barakah, we use light water as a moderator – one of the most ... WebControlling the reaction. So that nuclear reactions like those seen in nuclear bombs do not happen in power stations, the nuclear reaction must be controlled. Control rods
