Nuclear graphite - Wikipedia

Nuclear graphite is any grade of graphite, usually synthetic graphite, manufactured for use as a moderator or reflector within a nuclear reactor. Graphite is an important material for the construction of both historical and modern nuclear reactors, due to its extreme purity and ability to withstand … See more Nuclear fission, the creation of a nuclear chain reaction in uranium, was discovered in 1939 following experiments by Otto Hahn and Fritz Strassman, and the interpretation of their results by physicists such as See more In December 1942 Eugene Wigner suggested that neutron bombardment might introduce dislocations and other damage in the molecular structure of materials such as the graphite moderator in a nuclear reactor (the Wigner effect). The resulting … See more Nuclear graphite for the UK Magnox reactors was manufactured from petroleum coke mixed with coal-based binder pitch heated and extruded into billets, and then baked at 1,000 °C … See more • Manufacturing and Production of Graphite, IAEA Nuclear Graphite Knowledge Base • Graphite Behaviour under Irradiation, IAEA Nuclear Graphite Knowledge Base See more Reactor-grade graphite must be free of neutron absorbing materials, especially boron, which has a large neutron capture cross section. Boron sources in graphite include the raw … See more This describes the behavior of nuclear graphite, specifically when exposed to fast neutron irradiation.
