A procedure for the metallisation conditioning of radioactive graphite |
(57) The procedure for the metallisation conditioning of radioactive graphite from nuclear
plants or nuclear plant dismantling consists of the metallisation of the irradiated
graphite through a double and thin layer of copper-nickel for water-tightness purposes,
minimizing the lixivation of the radionucleids found inside and facilitating its handleability
by eliminating the unctuosity problem. The metallisation is carried out by an electrodeless
self-catalyst reduction of the metal salts found on the surface of the graphite where
previously the catalyst has been deposited and activated.
