Abstract
A process for the milling of a nuclear graphite contaminated with radioelements includes subjecting the graphite, immersed in a liquid medium, to high-voltage pulses. The liquid medium has a resistivity such that, owing to the effect of the energy conveyed by the said pulses, electric arcs are initiated and, upon contact with the graphite, break the carbon-carbon bonds that make up the graphite. The number of high-voltage pulses is set so as to obtain a given particle size.
