A moderator is in a nuclear reactor, it is 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.
