The regulations governing disposal criticality require that criticality not be possible, except under certain very unlikely sequences of events, and that the risk of criticality (probability times consequences) not violate repository performance guidelines. This paper describes the analysis and results of a probabilistic evaluation of the likelihood that the events/conditions required for a criticality event internal to the waste package (WP) during the postclosure phase of the repository will occur. This analysis supports a determination of licensability as it is affected by criticality control.
