Analytical study of TATB preheating methods

Description: TATB (1,3,5 - triamino 2,4,6 - Trinitrobenzene) is a very stable explosive that is remarkably insensitive to severe impact and thermal environment. Experiments on its initiation and detonation characteristics have found it difficult to initiate under the energy transfer of thin flyer plates accelerated by electrically exploded metal foils. Figure 1 shows the propagation of a detonation front in such an experiment. Generally, the detonation waves are confined in the region directly in front of t… more

LWRHU GTA Weld Development

Description: Nineteen LWRHU Development Welds have been made. Welds WD-1 through WD-4 were made early in the program to obtain preliminary joint design data. Welds WD-5 through WD-10 were made with the vertical leg of the shim located toward the closure end cap. A decision was made to locate the shim with the vertical leg on the fuel side of the capsule; therefore, the data obtained on the above capsule welds will not be included in this report. A tantalum pellet machined to the configuration of the fuel pe… more

Test results and supporting analysis of a near surface heater experiment in the Eleana Argillite

Description: A preliminary evaluation of the in-situ thermomechanical response of argillite to heating was obtained from a near-surface heater test in the Eleana Formation, at the Nevada Test Site. The experiment consisted of a 3.8 kW, 3-m long x 0.3-m diameter electrical heater in a central hole surrounded by peripheral holes containing instrumentation to measure temperature, gas pressures, and vertical displacement. A thermal model of the experiment agreed well with experimental results; a comparison of m… more

Petrology of tuff units from the J-13 drill site, Jackass Flats, Nevada

Description: The J-13 drill hole, located in Jackass Flats, Nevada Test Site, has penetrated 125 m of alluvium and 932 m of tuff. Most of the tuff deposits consist of welded tuffs; glass phases in the tuffs have been replaced by authigenic minerals, mainly K-feldspar, silica, and zeolites. The zonation of authigenic minerals, with depth, indictes that alteration of glass phases and filling of vugs occurred during welding and compaction of tuff units soon after deposition and by interaction with groundwater.… more

Applicability of microautoradiography to sorption studies

Description: The technique of microautoradiography was applied to the study of the sorption of uranium and americium on five rock types which exist at the Nevada Test Site. It was found that autoradiograms could be prepared in a few days which would allow the specific minerals responsible for sorption to be identified. Furthermore, the state of aggregation of the sorbed species was clearly indicated. It was concluded that microautoradiography was a useful adjunct to currently used methods for studying sorpt… more

Status of evaluation of tuff in southern Nevada for geologic disposal of high level nuclear wastes

Description: Siliceous tuff in southern Nevada occurs in a complex and locally active geological environment. Regional thrust faulting, Basin and Range faulting, and present-day seismicity complicate exploration and site characterization activities. The inherent variability of tuff and the complexity of caldera complexes also complicate siting efforts, but may serve to enhance long-term containment. Time--space trends of silicic volcanism are moderately well-established, while those of recent basaltic volca… more

Interaction of radionuclides with geomedia from the Nevada Test Site

Description: Aqueous/solid distribution coefficients have been measured for {sup 137}Cs, {sup 85}Sr, {sup 99}Tc, {sup 152}Eu, {sup 144}Ce, {sup 238}Pu, {sup 243}Am and {sup 244}Cm on powdered argillite and hornfels obtained from the Nevada Test Site. The fluid phases included a groundwater simulant and deionized water preequilibrated with powdered argillite. Distribution coefficients for lanthanides and actinides are generally high and Eleana shale was found to effectively sorb technetium.

Evaluation of tuff as a waste isolation medium

Description: Tuff is of interest for use as an isolation medium for high heat producing wastes because it provides highly sorptive minerals and suitable thermomechanical properties. Also, tuff is widespread in areas that offer long and deep groundwater flow paths. The occurrence and geologic/hydrologic setting of tuff are discussed. The properties of the rock are discussed and compared with other isolation media. The favorable and unfavorable aspects are presented. Also, unresolved issues are discussed alon… more

Sorption--desorption studies on argillite. I. Initial studies of strontium, technetium, cesium, barium, cerium, and europium

Description: Distribution ratios were determined for sorption--desorption of radioactive tracers between Eleana argillite available from the Nevada Test Site and a water prepared to be representative of the natural groundwater composition. The measurements were preformed at 22{sup 0}C and 70{sup 0}C under atmospheric oxygen conditions. The order of increasing distribution coefficient by element at both temperatures is Tc(VII), Sr, Cs, Ba, Eu, and Ce. The effects of surface area and mineralogy were also inve… more

Mechanical modeling of nuclear waste disposal in argillite at the Nevada Test Site

Description: Numerical calculations for a near surface heater experiment in argillite conducted at the Nevada Test Site were performed using the finite element code ADINA assuming a two-dimensional axisymmetric geometry. The existence and extent of the region of tensional opening of joints surrounding the heater, predicted by the mechanical model, were confirmed by posttest borehole inspection, permeability measurements, and drillback. Exrapolation of near surface heater model to repository depths reveals t… more

Preliminary evaluation of the radioactive waste isolation potential of the alluvium-filled valleys of the Great Basin

Description: The occurrences, geologic features, hydrology, and thermal, mechanical, and mineralogical properties of the alluvium-filled valleys are compared with those of other media within the Great Basin. Computer modeling of heat conduction indicates that heat generated by the radioactive waste can be dissipated through the alluvium in a manner that will not threaten the integrity of the repository, although waste emplacement densities will be lower than for other media available. This investigation has… more

Technical concept for rock mechanics tests, Climax Granite, NTS

Description: If we are to believe our predictions of the thermomechanical behavior of the material surrounding a nuclear waste repository in granite, we must test the computational methods used in making the predictions. If thermal loadings appropriate to a real repository are used, thermally induced displacements and strains are quite small, and available geotechnical instrumentation is only marginally able to measure these effects to the accuracy desired to make thorough tests of the predictions. We outli… more

Thermophysical properties of rocks: a perspective on data needs, sources and accuracy

Description: Recent emphasis on research in geologic isolation of nuclear wastes and geoenergy resource development has created a renewed demand for engineering thermophysical property data for rocks and other geologic materials at elevated pressures and temperatures. In contrast to fabricated engineering materials, with properties which can be specified, rocks used in engineering design are complex, naturally occurring materials having properties which must be characterized, rather than specified, for engi… more
