PROCEDE ET DISPOSITIF DE REDUCTION DES DECHETS RADIOACTIFS ET NOTAMMENT DE FILTRES DITS PIEGES A IODE, EN PARTICULIER DANS LES CENTRALES NUCLEAIRES ET DANS LES CENTRES D'ETUDES NUCLEAIRES

摘要

The present invention has for its object a process and a device for the reduction of radioactive wastes and particularly by regeneration of filters called iodine traps, in particular in nuclear centers and in centers for nuclear studies. Process characterized in that it is practiced by means of a mobile device and consists essentially, on site, in placing at least one filter (1) in a chamber (2), without preliminary disassembly, circulating hot air in this chamber (2), creating a vacuum in the chamber (2), so as to extract the pollutants, then impregnating, under vacuum, the active carbon of the filter (1) by means of a chemical impregnation product (3) such as an amine or an amine derivative. The invention is more particularly applicable to the field of treating nuclear waste, in particular by means of active carbon filters.
