NUSAFE - Reactor Safety

The assessment and improvement of the safety of nuclear reactors together with the protection of the population against radiation exposure constitute strategic long-term goals of the Helmholtz reactor safety research even after termination of nuclear electricity generation in Germany. The research in this topic concentrates on the one hand on the development of a coupled simulation tool that covers the complete calculation chain from the creation of input data over the conduction of core analyses until the analysis of design basis accidents. On the other hand, the research is dedicated to the further development of the international Severe Accident Management based on an improved plant-specific modeling of the possible radiological source term coupled with specific emergency management measures.
