Degraded Waste Package Criticality: Summary Report of Evaluations Through 1996

The purpose of this document is to summarize the degraded waste package disposal criticality evaluations which were performed in fiscal years I995 and I996. These evaluations were described in detail in 4 previous documents (Refs. I through 4). The initial version of this summary has been described in the I996 Disposal Criticality Analysis Methodology Technical Report (Ref. 5). A topical report planned for 1998 will present the methodology in its final form for approval by the US Nuclear Regulatory Commission.
The objective of this document is to show how the previous documents fit into an overall criticality evaluation methodology. This report is intended to provide technical support for the next revision of Disposal Criticality Analysis Methodology Technical Report (to be issued in September 1997).
