:''"Graphite reactor" directs here. for the graphite reactor at Oak Ridge National Laboratory, see X-10 Graphite 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 very first artificial nuclear reactor, the Chicago Pile-1, used graphite as moderator. Two graphite moderated reactors were involved in major accidents: An untested graphite annealing process contributed to the Windscale fire (but the graphite itself did not catch fire), and a graphite fire during the Chernobyl disaster contributed to the spread of radioactive material (but was not a cause of the accident itself). == Types == There are several types of graphite-moderated nuclear reactors that have been used in commercial electricity generation: *Gas-cooled reactors * *Magnox * *UNGG reactor * *Advanced gas-cooled reactor (AGR) *Water-cooled reactors * *RBMK * *EGP-6 *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 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Graphite-moderated reactor」の詳細全文を読む スポンサード リンク
