Abstract (en)
[origin: WO03050208A2] The invention concerns a method for treating a nuclear graphite contaminated by radioactive elements. Said method consists in subjecting said graphite, immersed in a water-containing medium, to high voltage pulses, said pulses having sufficient energy to generate electric arcs which breaks up the linkages constituting the water molecules and the carbon-carbon linkages of said graphite, the number of high voltage pulses being determined so as to obtain transformation of said graphite into gas.
