Description

This report describes the results of a study to investigate the influence of proposed exploratory shafts on the moisture distribution within unsaturated, fractured rock at Yucca Mountain, Nevada. The long-term effects of exploratory shafts at Yucca Mountain are important in the estimation of potential waste migration and fate, while short-term effects may be important in the planning and interpretation of tests performed at the site. The PORFLO-3 computer code was used for simulation of moisture flow through the geologic units adjacent to the ESF. Rather than represent fractures as discrete elements, an equivalent continuum was stipulated, in which the fractured ... continued below

Description

This report describes the results of a study to investigate the influence of proposed exploratory shafts on the moisture distribution within unsaturated, fractured rock at Yucca Mountain, Nevada. The long-term effects of exploratory shafts at Yucca Mountain are important in the estimation of potential waste migration and fate, while short-term effects may be important in the planning and interpretation of tests performed at the site. The PORFLO-3 computer code was used for simulation of moisture flow through the geologic units adjacent to the ESF. Rather than represent fractures as discrete elements, an equivalent continuum was stipulated, in which the fractured units were assigned equivalent or composite hydrologic properties. Explicit treatment of fractures is not feasible because of the extremely large number of fractures contained in the site-scale problem and the difficulties in characterizing and modeling the fracture geometries.
