There have been two major accidents in graphite-moderated reactors, the Windscale fire and the Chernobyl disaster. In the Windscale fire, an untested annealing process for the graphite was used, causing overheating in unmonitored areas of the core and leading directly to the ignition of the fire. The material that … See more 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 See more Nuclear fission, the creation of a nuclear chain reaction in uranium, was discovered in 1939 following experiments by Otto Hahn See more Reactor-grade graphite must be free of neutron absorbing materials, especially boron, which has a large neutron capture cross section. … 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 for several days. To reduce porosity and increase density, the billets were … 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 … See more This describes the behavior of nuclear graphite, specifically when exposed to fast neutron irradiation.
