Title: Generic criticality safety issues

An independent group has been designated by Martin Marietta Energy Systems, Inc., (MMES) to internally review Safety Analysis Reports for Packaging (SARPs) that describe containers for shipment of radioactive material. This group is called the Energy Systems Independent Review Group (ESIRG), reporting to the MMES Transportation Safety Manager as part of a central staff function. The ESIRG focus is Y-12 Plant packages, with additional review responsibilities for the Paducah Tiger UF{sub 6} overpack and 6M package. Review questions are posed directly to the SARP preparers. This paper addresses three generic issues that arose during the ESIRG criticality reviews: analysis tools, uncertainties in results, and resulting (finite) probability of criticality. 6 refs., 1 tab.
