Delphi analysis of radionuclide release scenarios for a nuclear waste repository at the Hanford site, Washington state: initial iteration

Technical Report ·
OSTI ID:6952543
The Columbia River basalts underlying the Hanford Site in Washington State are being characterized as a possible site for a nuclear waste repository. Identification, categorization, selection, and characterization of potential disruptions are important considerations for assessing long-term repository performance. Events, conditions, and processes potentially disruptive to repository isolation performance are analyzed by evaluating (1) uncertainties and omissions in characterizing the site; (2) credible events and processes resulting from the dynamics of natural systems; (3) changes in conditions affecting radionuclide isolation that are induced by the presence of the repository, and (4) credible changes to isolation capability resulting from human activities, other than repository construction or operation. Part I of this report presents the Basalt Waste Isolation Project methodology and rationale for identification, categorization, and initial analysis of potential Hanford Site candidate repository disruptions. Part II describes the implementation of the methodology and presents the results achieved. Part III consists of appendices to Parts I and II. This report will be a basis for future assessments of radionuclide release consequence scenarios. Several potential disruptions, will be selected for detailed characterization based on their assessments as bounding maximum potential radionuclide release risks for their respective occurrence probability categories. 83 references, 16 figures, 23 tables.
