In a nuclear fission reactor, the moderator slows fast neutrons down. Slower moving neutrons are more effective at keeping the chain reaction going by causing more uranium nuclei to break apart. Each fission event releases fast neutrons - the moderator is therefore required to slow them down

In a nuclear reactor, a material such as graphite or heavy water used to reduce the speed of high-energy neutrons. Neutrons produced by nuclear fission are fast-moving and must be slowed to initiate further fission so that nuclear energy continues to be released at a controlled rate. Slow neutrons are much more likely to cause fission in a ...
