PREFACE
The members of the Waste Package Materials Performance Peer Review Panel greatly appreciate the assistance of the Department of Energy staff and contractors responsible for evaluating the performance of waste package materials proposed for a repository at Yucca Mountain, Nevada. Despite heavy work schedules, they have responded willingly to requests for both information and meetings to assist the Panel in its review. Panel members also thank the Subject Matter Experts who have provided advice and information and prepared helpful background reports to assist the Panel in its deliberations. In addition, the staff of the U.S. Nuclear Regulatory Commission and their Center for Nuclear Waste Regulatory Analyses, members and staff of the U.S. Nuclear Waste Technical Review Board, and staff of the State of Nevada Agency for Nuclear Projects and its contractors have provided valuable assistance. The information and points-of-view they have provided have helped the Panel understand the range of technical issues involved in evaluating waste package materials and the work being done to resolve those issues.
