WebGraphite core design The UK has a long history of using graphite as a moderator from the early Magnox reactors to the Advanced Gas-cooled Reactors (AGRs). The moderator slows down the speed of neutrons produced during nuclear fission and helps to sustain the chain reaction so that the heat can be used for electricity production.
