The emplacement of nuclear waste in the proposed geologic repository must satisfy relevant regulatory requirements with respect to criticality, 10CFR60. I31 (h) (Ref. 25). The waste packages for the various waste forms will be designed to preclude criticality (typically by the inclusion of neutron absorbers) even if the waste package becomes filled with water. Criticality may, however, be possible if the contents of the waste package become degraded in such a way that the fissile material can be separated from the neutron absorbers, while sufficient moderator is retained. Several of the most likely degradation scenarios have been discussed in previous studies. Those studies reported in fiscal year (FY) 1995 and I996 have been summarized in Degraded Waste Package Criticality: Summary Report of Evaluations Through 1996 (Ref. I), together with the overall methodology which guided the individual studies.
