... on principles and operational strategies for the staged clevelopment of geologic repositories for radioactive high-level waste.2 Geologic repositories for high-level waste, as distinguished from many other waste disposal systems, are unique undertakings in that they are first-of-a-kind, risk-laden, complex, and fong-term projects.3 In the presence of such challenges, several international panels on radioactive waste management, including two previous National Research Council committees, recommended adopting a staged development approach. In agreement with this approach, the committee has further refined the concept of staged development and is currently discussing a concept that the committee calls "adaptive staging." The committee has yet to complete discussion of all the points listed in the statement of task (Attachment C)

... 5 Reversibility denotes the possibility of reversing one or a series of steps in repository development at any stage of the program. However, if no evidence questioning safety emerges as the program proceeds, decisions become firmer and reversal on technical ground becomes less likely.

... Although this is a staged development approach, this "modular repository design" is proposed to overcome annual budget restrictions, schedule, and regulatory uncertainties rather than to increase opportunities for learning, which would be the prime justification for implementing adaptive staging. Based on this work in progress, the committee believes that emphasizing further the funclamental attributes of adaptive staging could increase program flexibility and responsiveness to new information obtained during successive stages.
