In a thermal nuclear reactor, fission is primarily caused by slow-moving neutrons. The fast neutrons released during the fission of uranium need to be slowed down. A moderator is a material that slows down these fast neutrons through collisions without absorbing too many of them. Graphite is an effective moderator.
Graphite is used in the nuclear reactor as a
