Graphite Moderated Reactor

Graphite Moderated Reactor

A Graphite Reactor is a nuclear reactor that uses carbon as a neutron moderator, which allows un-enriched uranium to be used as nuclear fuel. The most famous would be the one that blew up causing the Chernobyl disaster. There are several types of graphite moderated nuclear reactors that have been used in commercial electricity generation:

  • Gas-cooled reactors
    • Magnox
    • Advanced gas-cooled reactor (AGR)
  • Water-cooled reactors
    • RBMK
  • High temperature gas-cooled reactors (past)
    • Dragon reactor
    • AVR
    • Peach Bottom Nuclear Generating Station, Unit 1
    • THTR-300
    • Fort St. Vrain Generating Station
  • High temperature gas-cooled reactors (in development or construction)
    • Pebble bed reactor
    • Prismatic fuel reactor
    • UHTREX Ultra High Temperature Reactor Experiment
