Part 1 of this report presents Rockwell methodology and rationale for identification, classification, and analysis of potential Hanford Site candidate repository disruptions. Part 2 describes the implementation of the methodology and presents the results achieved. Part 3 consists of appendices to Parts 1 and 2. The methodology employed is based on Nuclear Regulatory Commission and Environmental Protection Agency guidelines proposed in drafts of 10 CFR 60 and 40 CFR 191. In consideration of these guidelines, credible disruptive events, processes, and conditions are examined with respect to their relative occurrence probabilities and perceived release-risk consequences. A Delphi approach is used to (1) identify and categorize potential disruptions and (2) select potential disruptive events and processes for detailed characterization. This methodology is an auditable means of obtaining a consensus of opinion from individuals who are nationally recognized in the scientific community for their pertinent expertise. An independent consultant was employed to select 15 nationally recognized experts in the fields of geology, hydrology, geophysics, mining engineering, and climatology. These Delphi panelists were selected by a reputational survey of pertinent professional societies. Panelists categorized 45 scenarios according to site-specific occurrence probability and selected those scenarios from each occurrence probability category that they judged to have the most adverse release risk potential. 72 refs.
