Radioactive wastes of all kinds need to be managed responsibly to ensure public safety and protection of the environment, as well as security from malicious intervention, now and in the future. The most challenging task involves management of the long-lived waste that must be isolated from the human environment for many thousands of years. The preferred option for eventual disposal is emplacement in repositories deep underground in well-chosen geologica media.

This report presents and expert assessment of developments in the field of deep geologic disposal of radioactive waste over the past ten years. It reviews both technical and societal aspects, and should be of interest to decision makers responsible for radioactive waste management as well as to interested groups and individuals.
