Abstract

This report contains the information presented to the Working Group Meeting on NRC and DOE Performance Assessments: Assumptions and Differences. The U.S. Nuclear Regulatory Commission's (NRC) Advisory Committee on Nuclear Waste (ACNW) convened this Working Group on March 25-26, 2003 at the NRC Headquarters in Rockville, MD. This report includes summaries of the presentations given to the Committee, followed by the presentation materials and selected discussions among the participants. The working group included a panel of experts who observed and commented on the proceedings.

The purposes of the working group were (1) to increase the ACNW's technical knowledge of the performance assessment work being done for the proposed Yucca Mountain repository, (2) to identify "soft spots" in the analyses to date, particularly in regard to the issue of "model realism," (3) to compare the different approaches taken by the NRC and the U.S. Department of Energy, and (4) to provide a reference point to develop a follow-on working group on performance confirmation for Yucca Mountain.
