Preliminary three-dimensional discrete fracture model, Tiva Canyon tuff, Yucca Mountain area, Nye County, Nevada

Description: A three-dimensional discrete fracture model was completed to investigate the potential effects of fractures on the flow of water at Yucca Mountain, Nye County, Nevada. A fracture network of the Exploratory Studies Facility starter tunnel area was simulated and calibrated with field data. Two modeled volumes were used to simulate three-dimensional fracture networks of the Tiva Canyon tuff. One volume had a width and length of 150 meters, and the other had a width and length of 200 meters; both v… more

Preliminary three-dimensional discrete fracture model of the Topopah Spring tuff in the Exploratory Studies Facility, Yucca Mountain area, Nye County, Nevada

Description: Discrete-fracture modeling is part of site characterization for evaluating Yucca Mountain, Nye County, Nevada, as a potential high-level radioactive-waste repository site. Because most of the water and gas flow may be in fractures in low-porosity units, conventional equivalent-continuum models do not adequately represent the flow system. Discrete-fracture modeling offers an alternative to the equivalent-continuum method. This report describes how discrete-fracture networks can be constructed an… more

Exploration of the Upper Hot Creek Ranch Geothermal Resource, Nye County, Nevada

Description: The Upper Hot Creek Ranch (UHCR) geothermal system had seen no significant exploration activity prior to initiation of this GRED III project. Geochemical geothermometers calculated from previously available but questionable quality analyses of the UHCR hot spring waters indicated possible subsurface temperatures of +320 oF. A complex Quaternary and Holocene faulting pattern associated with a six mile step over of the Hot Creek Range near the UHCR also indicated that this area was worthy of some… more

Site characterization data from the Area 5 science boreholes, Nevada Test Site, Nye County, Nevada

Description: The Science Borehole Project consists of eight boreholes that were drilled (from 45.7 m [150 ft] to 83.8 m [275 ft] depth) in Area 5 of the Nevada Test Site, Nye County, Nevada, on behalf of the US Department of Energy. These boreholes are part of the Area 5 Site Characterization Program developed to meet data needs associated with regulatory requirements applicable to the disposal of low-level and mixed waste at this site. This series of boreholes was specifically designed to characterize para… more

Geohydrologic data collected from shallow neutron-access boreholes and resultant-preliminary geohydrologic evaluations, Yucca Mountain area, Nye County, Nevada

Description: In cooperation with the US Department of Energy, 74 neutron-access boreholes were drilled in and near the southwestern part of the Nevada Test Site, Nye County, Nevada. Drilling, coring, sample collection and handling, and lithologic and preliminary geohydrologic data are presented in this report. The boreholes were drilled in a combination of alluvium/colluvium, ash-flow tuff, ash-fall tuff, or bedded tuff to depths of 4.6 to 36.6 meters. Air was used as a drilling medium to minimize disturban… more

Chemistry of Diagenetically Altered Tuffs at a Potential Nuclear Waste Repository, Yucca Mountain, Nye County, Nevada

Description: The chemistry of diagenetically altered tuffs at a potential nuclear waste repository, Yucca Mountain, Nevada is described. These tuffs contain substantial amounts of zeolites that are highly sorptive of certain radionuclides. Because of their widespread distribution, the zeolitic tuffs could provide important barriers to radionuclide migration. Physical properties of these tuffs and of their constituent zeolites are influenced by their chemical compositions. This study defines the amount of ch… more
