The moderator in a nuclear power plant is the substance that is used to slow down neutrons that are generated by the fission reactions. When fissile material fissions, fission fragments appear, as do neutrons. These neutrons, which leave the fission reaction with a heap of kinetic energy, might go on to cause more fissions (in a chain reactions) if they can be thermalized (slowed). Slowing (moderating) the neutrons increases the probability that they will be absorbed to cause another fission.

Depending on the plant design, a few common ones now are:

  • water
  • heavy water
  • graphite
  • none (in fast breeder reactors)

How much graphite is used in a nuclear power plant per year?

United States nuclear power plants do not use graphite for operation and thus the answer is "none". Graphite is used in some reactor designs as a "moderator", which is the reactor feature that slows down neutrons so that the chain reaction will continue. US nuclear plants are "light water reactors" which means that they use regular water as the moderator. Canadian plants, for example, are "heavy water" plants which use duterium as a moderator. Chernobyl, the Ukranian plant that exploded in the 1980's, used graphite as a moderator.
