The development of radioactive waste repositories involves consideration of how the waste and the engineered barrier systems will evolve, as well as the interactions between these and, often relatively complex, natural systems. The timescales that must be considered are much longer than the timescales that can be studied in the laboratory or during site characterisation. These and other factors can lead to various types of uncertainty (on scenarios, models and parameters) in the assessment of long-term, post-closure performance of waste management facilities. This report includes a synthesis of the plenary presentations and the discussions that took place at the workshop organised under the auspices of the NEA Integration Group for the Safety Case (IGSC) on the “Management of Uncertainty in Safety Cases and the Role of Risk”.
