Compared to other large engineering projects, geologic repositories for high-level waste present distinctive challenges because: 1) they are first-of-a-kind, complex, and long-term projects that must actively manage hazardous materials for many decades; 2) they are expected to hold these hazardous materials passively safe for many millennia after repository closure; and 3) they are widely perceived to pose serious risks. As is the case for other complex projects,1 repository programs should proceed in stages. Recognizing the potential benefits of staging in managing a geologic repository program, the Department of Energy (DOE) asked the National Research Council for advice on how to implement staging during the construction, operation, closure, and post-closure phases of repository development. This study provides a discussion of the meaning of repository staging focusing specifically on programmatic, safety, security, institutional, regulatory, and societal factors. The report addresses staging primarily as applied to a generic repository program with applications to the U.S. program at Yucca Mountain (the Yucca Mountain Project). The statement of task is broad, in that it required the examination of scientific, technical, policy, and societal issues. The project management recommendations in this report are based upon the combined judgment and expertise of committee members rather than on direct experience with implementation of staged ap- proaches. The committee believes that the approach recommended will increase the likelihood of repository program success (as defined in Section 1.2.2) because it is consistent with accepted principles of sound project management and good engineering practices.
