By Committee on Principles and Operational Strategies for Staged Repository Systems, National Research Council

In comparison to different huge engineering initiatives, geologic repositories for high-level waste current precise demanding situations simply because: they're first-of-a-kind, complicated, and long term tasks that needs to actively deal with detrimental fabrics for plenty of a long time; they're anticipated to carry those harmful fabrics passively secure for plenty of millennia after repository closure; and they're greatly gave the impression to pose severe dangers. As is the case for different advanced tasks, repository courses should still continue in phases. "One Step at a Time" specializes in a administration technique referred to as "adaptive staging" as a promising potential to strengthen geologic repositories for high-level radioactive waste comparable to the proposed repository at Yucca Mountain, Nevada. Adaptive staging is a learn-as-you-go method that permits undertaking managers to continually reevaluate and alter this system in keeping with new wisdom and stakeholder enter. suggestion is given on easy methods to enforce staging throughout the development, operation, closure, and post-closure levels of a repository application.

This perception may be mitigated by using Adaptive Staging when compared to a management approach that sets up and advertises fixed milestones that will inevitably need to be revised with time. In summary, Adaptive Staging is a cautious and deliberate decision-making and management process, fully consistent with good engineering practices. It emphasizes continuous learning, both technical and societal, includes scientific and managerial re-evaluations and reactions to new knowledge, is responsive to stakeholder input, and is designed to continually improve the project while retaining the option of reversibility as much as possible.

Kennedy had promised in 1961: to land a man on the Moon within a decade. The program’s goal was essentially geopolitical, to demonstrate to the world the prowess of the United States, and this it did, on schedule. The program received generous financial resources and political support; cost overruns were not a factor in determining success. Supporters could tolerate a few years of overruns; annual program costs peaked two years before the Moon landing, and their decline encouraged continued support (Konkel, 1990).

Decides on the next stage based on all of the above; and 7. disseminates decisions and their rationales. 1a, b, and c illustrate schematically the committee’s view of the overall Adaptive Staging process, stages, and Decision Points. The more important or farreaching the decision, the more it resembles the Decision Point-process above. Of course, the program implementer makes many more decisions than those at the formal Decision Points. 7 Because reversibility is always an option, it is important that the repository program provide flexibility in its reference framework.
