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 This describes the behavior of nuclear graphite, specifically when exposed to fast neutron irradiation. Specific phenomena addressed: • Dimensional change (shrinkage and neutron-induced swelling, as well as possible hardening) See more There have been two major accidents in graphite-moderated reactors, the Windscale fire and the Chernobyl disaster.
