A probabilistic safety assessment study is performed for a repository placed in a bedded salt formation using a fault tree analysis approach and the capabilities of IRRAS-PC code. The sensitive areas in repository safety are identified, and results for different risk importance measures are reported. Two release scenarios based upon human intrusion are also studied. The impact of both intact and degraded institutional control on risks to future generations is assessed. As a result of this analysis, the important events for future investigations are identified as faulting, groundwater movement, human activities, and erosion. 23 refs., 5 figs., 8 tabs.
