[en] To comply with regulations and to ensure state of the art treatment of historical conditioned radioactive waste in Austria, as well as to guarantee safe interim storage until 2045, historic conditioned radioactive waste is being reconditioned in an ongoing project. Drums with waste forms of all three main conditioning types (drums with super-compacted pellets, homogeneously cemented and in-homogeneously cemented drums) found in Austria have already been reconditioned. Experiences from the reconditioning of all three types of drums and information regarding the status of the project is being shared. Steps of special importance proved to be the pre-sorting of the different waste types derived from existing documentation, the use of a specialized modular machinery for the dismantling of the drums layer by layer to limit cross-contamination, and the characterization of the waste performed in tandem and afterwards. As a last step, documentation of the original drum is consolidated with the information from the reconditioning processes and from radiological and chemical assays. (author)
