Considering the fact that to our experiences fire accidents are of highest significance for the operational safety of a repository for Radwaste, a broad research project has been carried out in Germany on behalf of BfS (Federal Office for Radiation Protection) to develop a comprehensive approach for the determination of release rates under fire conditions. Various experiments were performed to target at the adjustment of theoretical models within safety and risk analysis of such installation. The investigations included the study of the release mechanisms caused by combustion of radioactive waste and the heating up of radioactive metallic scrap as well as the research of the behavior of an inactive waste drum in an open fire and the release rates out of waste simulation material. The experiments resulted in the identification of release rates as a consequence of thermal impact on Radwaste to allow a more realistic look at the nuclide specific risks and their consequences for safety assessments. Finally release fractions are calculated based on the thermal behavior of elements in the case of fire and their release rates. (authors)
