Advance Abrasion Resistant Materials for Mining

Description: The high-density infrared (HDI) transient-liquid coating (TLC) process was successfully developed and demonstrated excellent, enhanced (5 times higher than the current material and process) wear performance for the selected functionally graded material (FGM) coatings under laboratory simulated, in-service conditions. The mating steel component exhibited a wear rate improvement of approximately one and a half (1.5) times. After 8000 cycles of. wear testing, the full-scale component testing demon… more

Advanced Conceptual Models for Unsaturated and Two-Phase Flow in Fractured Rock

Description: The Department of Energy Environmental Management Program is faced with two major issues involving two-phase flow in fractured rock; specifically, transport of dissolved contaminants in the Vadose Zone, and the fate of Dense Nonaqueous Phase Liquids (DNAPLs) below the water table. Conceptual models currently used to address these problems do not correctly include the influence of the fractures, thus leading to erroneous predictions. Recent work has shown that it is crucial to understand the top… more

Alternative Ionization Methods for Particle Mass Spectrometry

Description: The objective of this project is to enhance the capabilities of a real-time airborne particle mass spectrometer by implementing matrix-independent methods for sample ionization. The enhancements should result in improved sensitivity for trace substances and, more importantly, permit quantitative determination of the presence of target species in microparticle samples on an individual particle basis. We have used two different approaches to eliminate matrix effects on quantitative accuracy. Both… more

Application of Advanced Gamma Ray Detection Concepts Combined with Real-time Compton Suppression for Nondestructive, Gamma Ray Characterization of Remote-handled Waste

Description: Nondestructive gamma ray characterization of remote-handled waste is significantly complicated by the presence of Compton scattering in the detector and waste matrix produced by the intense cesium gamma ray. This research seeks to understand the photophysics of a new type of inorganic scintillation gamma ray detector, optimize the combination of this gamma ray detector with a Compton guard detector, develop new Monte Carlo solution algorithms for modeling Compton scattering in the waste, and to… more

The Aqueous Thermodynamics and Complexation Reactions of Anionic Silica and Uranium Species to High Concentration

Description: Highly basic tank wastes contain several important radionuclides, including 90Sr, 99Tc, and 60Co, as well as actinide elements (i.e., isotopes of U, Pu, and Am). These highly basic tank wastes are known to have leaked into the vadose zone at the Hanford Site. Upon entering the sediments in the vadose zone, the highly basic solutions dissolve large concentrations of silica from the silica and aluminosilicate minerals present in the subsurface. These dissolution reactions alter the chemical compo… more

Characterization of Actinides in Simulated Alkaline Tank Waste Sludges and Leachates

Description: Treatment of underground tanks at Hanford with concentrated alkali to improve removal of wastelimiting components of sludges has proven less efficacious for Al and Cr removal than had been hoped. Hence, more aggressive treatments of sludges, including contact with oxidants targeting Cr(III), have been tested in a limited number of samples and found to enhance Cr removal. Unfortunately, treatments of sludge samples with oxidative alkaline leachates produce conditions under which normally insolub… more

Characterization of Coupled Hydrologic-Biogeochemical Processes Using Geophysical Data

Description: Biogeochemical and hydrological processes are naturally coupled and variable over a wide range of spatial and temporal scales. Additionally, many remediation approaches also induce dynamic transformations in natural systems. Because it is difficult to predict these transformations, our ability to develop effective and sustainable remediation conditions at contaminated sites is often limited. For example, substrate delivery to enhance remediation via biostimulation may initially prove effective,… more
