Grey sets theory based approach for assessing the vulnerability of safeguarding a geological repository

    Research outputpeer-review


    Safeguards approaches for geological repositories are currently under development in the IAEA ASTOR working group and a number of institutions worldwide. In this paper we propose a new method for the assessment of the vulnerability of safeguarding a geological repository. This method draws on recent vulnerability analysis methods proposed in the literature and on multi-criteria analysis theory. In addition, uncertainty in the estimation of the different vulnerability criteria is tackled based on grey theory, which allows expressing uncertainty as intervals of values (grey numbers) and offers ways to adapt known aggregation methods. Finally, we discuss the robustness of various safeguards strategies with respect to five acquisition paths. As an exemplary case study we discuss the operational stage of a geological repository.
