Safety Evaluation Report for Disposal Criticality Analysis Methodology Topical Report, Revision 0

In January 1999, the U.S. Department of Energy (DOE)/Office of Civilian Radioactive
Waste Management (OCRWM) submitted the Disposal Criticality Analysis Methodology
Topical Report, Revision 0 (TR) to the U.S. Nuclear Regulatory Commission (NRC) for
review and approval. The TR presents an overall approach for consideration of postclosure
disposal criticality of commercial and defense high-level waste to be placed at
the proposed Yucca Mountain site. During the course of the review and interactions
with the DOE, through a series of technical exchanges and a request for additional
information (RAI), the scope of the TR was focused on specific aspects of the
methodology. This safety evaluation report (SER) presents the results of the NRC staff
evaluation of those specific aspects of the methodology. The NRC staff has presented
the results of its evaluation in terms of Acceptance, Confirmatory Items, or Open Items
throughout the SER. The Open Items from all the sections are listed in the Conclusion
section.
