After being used for its energy-producing, medical or industrial properties, and after possibly being reused further to reprocessing, the radioactive material becomes a waste which must be managed in a manner appropriate to the danger it represents. Preventing and reducing the production and harmfulness of the waste This fundamental principle is enshrined in the regulations. The waste producers must present and justify their actions in this respect. The waste is collected, characterised and sorted The waste can then be conditioned as an interim (non-systematic) or final solution, having first been reprocessed if necessary. production of waste sorting Several possible techniques • Volume reduction (melting, incineration, compacting, etc.) • Decontamination • Physical-chemical treatment (dissolution, evaporation, etc.) The steps in radioactive waste management Volume reduction Decontamination Chemical treatment * See glossary page 34 processing* of the waste 12 • Les cahiers de l’ASN • May 2024 WHAT WASTE ARE WE TALKING ABOUT?
