Abstract

Safe management of nuclear wastes is a critical aspect in ensuring the sustainability of the nuclear industry in some countries and/or to end legacy practices in other countries. Currently, these wastes are managed according to the containment and confinement option, where their radiological hazards are contained by isolating the wastes for a sufficient period to allow the decay of short-lived radioanuclides and limit the release of long-lived radionuclides. Conditioning is a predisposal activity that aims to produce an optimized waste package. Conditioning includes producing optimized waste form and encloses it in a suitable package. This work aims at summarizing the technical and academic efforts toward the optimization of the conditioning process and identifying the gaps in this area. Within this context, radioactive/nuclear waste classification and different activities in integrated radioactive waste management schemes will be introduced. Conventional and innovative conditioning technologies will be overviewed. Methods to assess the optimized performance of these wastes will be summarized. Finally, methods to address the conditioning of problematic wastes and the required research efforts in this field will be identified.
