ABSTRACT:
Process for the conditioning or recycling of used ion cartridges.
The invention relates to a process for the treatment of ion cartridges or elements ensuring the treatment of contaminated waters of storage ponds or pools for nuclear reactor fuels. By cartridge transfer and suction means, said treatment consists of extracting the ion exchange resins contained in the cartridge.
When the resin has been extracted, a conditioning process makes it possible to decontaminate and then condition, independently of the resinous substance, the metal structure constituting the cartridge.
When the resin has been extracted, a recycling process makes it possible to clean the impurities from the metal structure and fill it again with new resin.
The invention has applications in the nuclear field and in particular in the field of treatment and conditioning of nuclear waste.
