Comparison of the Layer Structure of Vapor Phase and Leached SRL Glass by Use of AEM [Analytical Electron Microscopy]

Description: Test samples of 131 type glass that have been reacted for extended time periods in water vapor atmospheres of different relative humidities and in static leaching solution have been examined to characterize the reaction products. Analytical electron microscopy (AEM) was used to characterize the leached samples, and a complicated layer structure was revealed, consisting of phases that precipitate from solution and also form within the residual glass layer. The precipitated phases include birnes-… more

The reaction of synthetic nuclear waste glass in steam and hydrothermal solution

Description: Glass monoliths of the WVCM 44, WVCM 50, SRL 165, and SRL 202 compositions were reacted in steam and in hydrothermal liquid at 200{degree}C. The glass reaction resulted in the formation of leached surface layers in both environments. The reaction in steam proceeds at a very low rate until precipitates form, after which the glass reaction proceeds at a greater rate. Precipitates were formed on all glass types reacted in steam. The assemblage of phases formed was unique to each glass type, but se… more

Color palette: Plotting guide for use with GSMAP and GSDRAW digital cartographic software

Description: Guidelines for plotting a variety of colors and patterns using GSMAP and GSDRAW digital cartographic programs have been developed. These color and pattern variations can be used to fill polygons (areas) on maps, charts, or diagrams. Batch processing file for plotting a sample color/pattern palette on a Hewlett Packard 7585B 8-pen plotter using GSDRAW software are provided on the disk. The detailed instructions, batch processing files, and variables used to construct the palette will provide the… more

TURBOSEIS---An interactive program for constructing and editing models of seismic refraction traveltime data using a color-graphics terminal

Description: TURBOSEIS is a FORTRAN computer program designed to assist the user in interactively developing seismic refraction traveltime curves (models), to evaluate the number of refracting horizons at depth in a study area. TURBOSEIS allows one to generate a detailed traveltime curve for each of these layers that can then be input into the programs of Ackermann (Ackermann and other 1986) for inversion of the velocity distribution as a function of depth. This report describes the mechanics of using the p… more

Horizontal coring using air as the circulating fluid: Some prototype studies conducted in G Tunnel at the Nevada Test Site for the Yucca Mountain Project

Description: Horizontal coring using air as the circulating fluid has been conducted in the G Tunnel Underground Facility (GTUF) at the Nevada Test Site. This work is part of the prototype investigations of hydrogeology for the Yucca Mountain Project. The work is being conducted to develop methods and procedures that will be used at the Department of Energy`s Yucca Mountain Site, a candidate site for the nation`s first high-level nuclear waste repository, during the site characterization phase of the invest… more

Characterization of liquid-water percolation in tuffs in the unsaturated zone, Yucca Mountain, Nye County, Nevada

Description: A surface-based borehole investigation currently (1989) is being done to characterize liquid-water percolation in tuffs of Miocene age in the unsaturated zone beneath Yucca Mountain, Nye County, Nevada Active in-situ testing and passive in-situ monitoring will be used in this investigation to estimate the present-day liquid-water percolation (flux). The unsaturated zone consists of a gently dipping sequence of fine-grained, densely fractured, and mostly welded ash-flow tuffs that are interbedde… more

Physical and Chemical Characteristics of Topographically Affected Airflow in an Open Borehole at Yucca Mountain, Nevada

Description: Borehole UZ6S, on the crest of Yucca Mountain, Nevada Test Site, has exhaled approximately 10{sup 6} m{sup 3} of gas annually during winter months for three successive years. The flow arises from thermal-topographic effects. The average composition of the exhausted gas is: N{sub 2} = 78%, O{sub 2} = 21%, Ar = 0.94%, CO{sub 2} = 0.125%, and CH{sub 4} = 0.2 ppMv. The CO{sub 2} has the following isotopic signature: {sup 14}C = 108.5 percent modern carbon (pmc), and {delta}{sup 13}C = 17.1 per mil.… more
