Advanced Hydride Laboratory

Description: The Replacement Tritium Facility (RTF) is a $140 million reservoir loading and unloading facility using state-of-the-art technology, scheduled for completion in 1990 and startup in 1991. In the RTF, metal hydride technology will be used to store, separate, purify, pump, and compress hydrogen isotopes. In support of the RTF, a $3.2 million ``cold`` process demonstration facility began operation in November, 1987. The purpose of the Advanced Hydride Laboratory (AHL) is to demonstrate the RFT`s me… more

Description: Laminar natural convection is a two-dimensional cavity with a line heat sink at the top boundary is investigated numerically. The fluid in the cavity is a high Prandtl number fluid with volumetric heat source. Parametric study is conducted to find the effect of variations in Rayleigh number, aspect ratio, sink location, and volumetric heat source on the flow and temperature field. 5 refs.

Background modelling in Rietveld analysis

Description: The Rietveld method is a complete profile fitting technique, which requires modelling the total scattering from crystalline samples. Many diffraction experiments involve the analysis of scattering patterns containing additional noncrystalline scattering components; these components are broad oscillations superimposed on the sharp Bragg pattern. Conventional background functions cannot be used for the noncrystalline scattering; but treating the additional scattering as though it were from an amo… more

Burning of a spherical fuel droplet in a uniform subsonic flowfield

Description: An analytical/numerical model is described for the evaporation and burning of a spherical fuel droplet in a subsonic crossflow. The external gaseous flowfield is represented using an approximate compressible potential solution, while the internal flowfield of the droplet is represented by the classical Hill`s spherical vortex. This allows numerical solution for the external boundary layer and diffusion flame characteristics to be made, from which the droplet`s effective drag coefficient, rate o… 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

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

Control of DWPF melter feed composition

Description: The Defense Waste Processing Facility will be used to immobilize Savannah River Site high-level waste into a stable borosilicate glass for disposal in a geologic repository. Proper control of the melter feed composition in this facility is essential to the production of glass which meets product durability constraints dictated by repository regulations and facility processing constraints dictated by melter design. A technique has been developed which utilizes glass property models to determine … more

The development of early pediatric models and their application to radiation absorbed dose calculations

Description: This presentation will review and describe the development of pediatric phantoms for use in radiation dose calculations . The development of pediatric models for dose calculations essentially paralleled that of the adult. In fact, Snyder and Fisher at the Oak Ridge National Laboratory reported on a series of phantoms for such calculations in 1966 about two years before the first MIRD publication on the adult human phantom. These phantoms, for a newborn, one-, five-, ten-, and fifteen-year old, … more

Fabricating vanadium sheet to improve symmetry of drawn parts

Description: The degree of anisotropy in vanadium sheet determines the amount of earing in formed parts and relates to the roundness of the formed part. Experiments with annealing and rolling practices to produce vanadium sheet were undertaken to reduce the earing tendencies of the metal. Earing in formed vanadium hemishells was reduced by cross rolling; and for unidirectionally rolled sheet, increased reduction per rolling pass and proper selection of intermediate annealing temperature reduced the earing. … more

Flow boiling in vertical down-flow

Description: An experimental program has been conducted to investigate the onset of Ledinegg instability in vertical down-flow. For three size uniformly heated test sections with L/D ratios from 100 to 150, the pressure drop under subcooled boiling conditions has been obtained for a wide range of operating parameters. The results are presented in non-dimensional forms which correlate the important variables and provide techniques for predicting the onset of flow instability. 3 refs.

Genome sequencing by direct imaging x-ray color holography. Appendix A

Description: Currently available techniques for sequencing DNA are inadequate for oligonucleotides of length greater than 600 nucleotides and are most effective in the 300 nucleotide range. Automated sequencers are now available which use, basically, the Sanger dideoxy termination method. The sequencing rates of these conventional methods are extremely low and involve very labor intensive procedures, requiring on the order of two man-years of effort for the determination of the sequence of a single 100 kilo… more

A hierarachical data structure representation for fusing multisensor information

Description: A major problem with MultiSensor Information Fusion (MSIF) is establishing the level of processing at which information should be fused. Current methodologies, whether based on fusion at the data element, segment/feature, or symbolic levels, are each inadequate for robust MSIF. Data-element fusion has problems with coregistration. Attempts to fuse information using the features of segmented data relies on a Presumed similarity between the segmentation characteristics of each data stream. Symbol… more

Description: A major problem with image-based MultiSensor Information Fusion (MSIF) is establishing the level of processing at which information should be fused. Current methodologies, whether based on fusion at the pixel, segment/feature, or symbolic levels, are each inadequate for robust MSIF. Pixel-level fusion has problems with coregistration of the images or data. Attempts to fuse information using the features of segmented images or data relies an a presumed similarity between the segmentation charact… more

An introduction to geographic information systems as applied to a groundwater remediation program

Description: While the attention to environmental issues has grown over the past several years, so has the focus on groundwater protection. Addressing the task of groundwater remediation often involves a large-scale program with numerous wells and enormous amounts of data. This data must be manipulated and analyzed in an efficient manner for the remediation program to be truly effective. Geographic Information System`s (GIS) have proven to be an extremely effective tool in handling and interpreting this typ… more
