The DOE`s Office of Civilian Radioactive Waste Management is in the process of characterizing the Yucca Mountain site, Nye County, Nevada, to evaluate its suitability for development of a geologic repository for spent fuel and high-level radioactive waste. If the site is found suitable, much of these data and analyses can be used in an application for a license to the Nuclear Regulatory Commission. The topical report and methodology described in this paper represent a revision of the deterministic and probabilistic approaches to assessing seismic hazards described in DOE`s Site Characterization Report. The proposed probabilistic methodology incorporates experience gained while siting and licensing nuclear power plants and other critical facilities during the past decade. In contrast to the traditional deterministic approach, this methodology incorporates all available geologic, geophysical, and seismological data; frequency of occurrence; and variability and uncertainty in both conceptual models and parameters. It also integrates the hazard from all potential sources. Probabilistic approaches have been used primarily to assess hazards from vibratory ground motion, but this approach also applies to assessing fault displacement hazards. The proposed methodology will provide input for design of surface and subsurface facilities (pre- and postclosure periods) and for performance assessment.
