Nuclear graphite - Wikipedia

Nuclear graphite is any grade of graphite, usually synthetic graphite, specifically 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 its ability to withstand extremely high temperatures.Graphite has also recently been used in nuclear ...

Graphite - Wikipedia

Graphite (/ ˈ ɡ r æ f aɪ t /), archaically referred to as plumbago, is a crystalline form of the element carbon with its atoms arranged in a hexagonal structure.It occurs naturally in this form and is the most stable form of carbon under standard conditions.Under high pressures and temperatures it converts to diamond.Graphite is used in pencils and lubricants.

Thermal oxidation of nuclear graphite: A large scale waste ...

This study has investigated the laboratory scale thermal oxidation of nuclear graphite, as a proof-of-concept for the treatment and decommissioning of reactor cores on a larger industrial scale. If showed to be effective, this technology could have promising international significance with a considerable impact on the nuclear waste management problem currently facing many countries worldwide.

Canada Carbon - Nuclear Grade Graphite Confirmed

The Miller hydrothermal lump-vein historical graphite mine is located 80 km west of Montreal in the Grenville Township and exhibits extremely high purity graphite grading 100% Cg. We have shown that the graphite could be suitable for use in nuclear reactors, with a calculated EBC of 0.94 ppm, as compared to the required maximum levels, typically between 1 and 3ppm.

Graphite as a core material for Generation IV nuclear reactors

14.1. Introduction. Along with the use of carbon-coated uranium oxide fuel articles , the use of graphite as a moderator for Generation IV reactors is attractive because it allows a reactor core to be designed in a way which, in fault conditions, can reach high enough temperatures to allow the “Doppler effect” to come into play which will shut down the reactor.
