Methodology for evaluating safeguard measures in long-term safety analyses for final repositories

The non-proliferation of nuclear material and the long-term protection of people and the environment are central tasks of the nuclear regulatory framework. In the context of final storage, safeguards measures are necessary to reliably verify the integrity and inaccessibility of waste containing nuclear material. The project systematically records the current state of science and technology relating to safeguards monitoring techniques for final repositories, focusing on technologies that can be used to monitor final repositories. Based on this, the potential safety-related influences of these monitoring measures on the final repository system are qualitatively evaluated and assigned to the corresponding entries in FEP catalogs (features, events, processes). The aim is to develop a methodology with which safeguards monitoring measures can be integrated into long-term safety analysis procedures. The project will investigate which safety-related statements can be made in the individual steps of a safety analysis if the measures are methodically taken into account via FEP catalogs. Finally, the developed methodology will be applied to selected safeguards monitoring measures and to a documented final repository system in a specific host rock.
