Book Geohydrologic Data from Test Holes UE 25 UZ number sign 4 and UE 25 UZ number sign 5 Yucca Mountain Area Nye County Nevada

Download or read book Geohydrologic Data from Test Holes UE 25 UZ number sign 4 and UE 25 UZ number sign 5 Yucca Mountain Area Nye County Nevada written by and published by . This book was released on 1992 with total page 56 pages. Available in PDF, EPUB and Kindle. Book excerpt: Data collected to determine the hydraulic characteristics of rocks penetrated by test holes UE-25 UZ No. 4 and UE-25 UZ No. 5 are presented. These test holes are part of a series of test holes drilled in and near the southwestern part of the Nevada Test Site in an investigation conducted by the US Geological Survey in cooperation with the US Department of Energy. This investigation is part of the Yucca Mountain Project Branch, Hydrologic Investigations Program (formerly Nevada Nuclear Waste Storage Investigations) to determine the suitability of this site for storage of high-level radioactive wastes in an underground mined repository. Data on drilling operations, lithology, coring, and laboratory analyses of hydrologic characteristics of core and cuttings samples are included in this report.

Book Characterization of Hydrogeologic Units Using Matrix Properties Yucca Mountain Nevada

This book was released on 2001 with total page 69 pages. Available in PDF, EPUB and Kindle. Book excerpt: Determination of the suitability of Yucca Mountain, in southern Nevada, as a geologic repository for high-level radioactive waste requires the use of numerical flow and transport models. Input for these models includes parameters that describe hydrologic properties and the initial and boundary conditions for all rock materials within the unsaturated zone, as well as some of the upper rocks in the saturated zone. There are 30 hydrogeologic units in the unsaturated zone, and each unit is defined by limited ranges where a discrete volume of rock contains similar hydrogeologic properties. These hydrogeologic units can be easily located in space by using three-dimensional lithostratigraphic models based on relationships of the properties with the lithostratigraphy. Physical properties of bulk density, porosity, and particle density; flow properties of saturated hydraulic conductivity and moisture-retention characteristics; and the state variables (variables describing the current state of field conditions) of saturation and water potential were determined for each unit. Units were defined using (1) a data base developed from 4,892 rock samples collected from the coring of 23 shallow and 8 deep boreholes, (2) described lithostratigraphic boundaries and corresponding relations to porosity, (3) recognition of transition zones with pronounced changes in properties over short vertical distances, (4) characterization of the influence of mineral alteration on hydrologic properties such as permeability and moisture-retention characteristics, and (5) a statistical analysis to evaluate where boundaries should be adjusted to minimize the variance within layers. This study describes the correlation of hydrologic properties to porosity, a property that is well related to the lithostratigraphy and depositional and cooling history of the volcanic deposits and can, therefore, be modeled to be distributed laterally.

Book Geohydrologic Data from Test Hole USW UZ 6s Yucca Mountain Nye County Nevada

Download or read book Geohydrologic Data from Test Hole USW UZ 6s Yucca Mountain Nye County Nevada written by and published by . This book was released on 1993 with total page 25 pages. Available in PDF, EPUB and Kindle. Book excerpt: As part of the investigation of Yucca Mountain, Nevada, as a potential site for storing high-level radioactive wastes in an underground mined geologic repository, the US Geological Survey, in cooperation with the US Department of Energy, in 1982, began drilling a series of test holes in and near the southwestern part of the Nevada Test Site to determine the geologic and hydrologic characteristics of the area. Test hole USW UZ-6s is part of that series of test holes, and this report presents data obtained from test hole USW UZ-6s. The data includes those from drilling operations, lithology, coring, and laboratory analyses of hydrologic properties, which include gravimetric water content, water potential, and bulk- and grain-density values. The gravimetric water content of the densely welded section of the Tiva Canyon Member of the Paintbrush Tuff averages 0.027 gram per gram for test hole USW UZ-6s; water potential averages -7,200 kilo-pascals; gravimetric water content of the moderately to densely welded tuffs range from 0.054 gram per gram for the Tiva Canyon Member of the Paintbrush Tuff to 0.027 gram per gram for the Topopah Spring Member of the Paintbrush Tuff; and water potentials range from -6,700 to -3,400 kilopascals. Gravimetric water content for the partially welded to unnamed bedded tuffs average 0.123, 0.106, and 0.085 gram per gram for the Tiva Canyon Member, the unnamed bedded tuffs, and the Topopah Spring Member in test hole USW UZ-6s; average water potentials for these units are -1,700, -480, and -820 kilopascals.
