Advance Abrasion Resistant Materials for Mining (open access)

Advance Abrasion Resistant Materials for Mining

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 demonstrated that the coating integrity was still excellent. Little or no spalling was observed to occur.

Advanced Conceptual Models for Unsaturated and Two-Phase Flow in Fractured Rock (open access)

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

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 topology, or ''structure'' of the fluid phases (air/water or water/DNAPL) within the subsurface. It has also been shown that even under steady boundary conditions, the influence of fractures can lead to complex and dynamic phase structure that controls system behavior, with or without the presence of a porous rock matrix. Complicated phase structures within the fracture network can facilitate rapid transport, and lead to a sparsely populated and widespread distribution of concentrated contaminants; these qualities are highly difficult to describe with current conceptual models. The focus of our work is to improve predictive modeling through the development of advanced conceptual models for two-phase flow in fractured rock.

Advanced Oxyfuel Boilers and Process Heaters for Cost Effective CO2 Capture and Sequestration (open access)

Advanced Oxyfuel Boilers and Process Heaters for Cost Effective CO2 Capture and Sequestration

This annual technical progress report summarizes the work accomplished during the second year of the program, January-December 2003, in the following task areas: Task 1--Conceptual Design, Task 2--Laboratory Scale Evaluations, Task 3--OTM Development, Task 4--Economic Evaluation and Commercialization Planning and Task 5--Program Management. The program has experienced significant delays due to several factors. The budget has also been significantly under spent. Based on recent technical successes and confirmation of process economics, significant future progress is expected. Concepts for integrating Oxygen Transport Membranes (OTMs) into boilers and process heaters to facilitate oxy-fuel combustion have been investigated. OTM reactor combustion testing was delayed to insufficient reliability of the earlier OTM materials. Substantial improvements to reliability have been identified and testing will recommence early in 2004. Promising OTM material compositions and OTM architectures have been identified that improve the reliability of the ceramic elements. Economic evaluation continued. Information was acquired that quantified the attractiveness of the advanced oxygen-fired boiler. CO{sub 2} capture and compression are still estimated to be much less than $10/ton CO{sub 2}.

Advanced Signal Analysis for Forensic Applications of Ground Penetrating Radar (open access)

Advanced Signal Analysis for Forensic Applications of Ground Penetrating Radar

Ground penetrating radar (GPR) systems have traditionally been used to image subsurface objects. The main focus of this paper is to evaluate an advanced signal analysis technique. Instead of compiling spatial data for the analysis, this technique conducts object recognition procedures based on spectral statistics. The identification feature of an object type is formed from the training vectors by a singular-value decomposition procedure. To illustrate its capability, this procedure is applied to experimental data and compared to the performance of the neural-network approach.

Advanced Technology Vehicle Testing (open access)

Advanced Technology Vehicle Testing

The goal of the U.S. Department of Energy's Advanced Vehicle Testing Activity (AVTA) is to increase the body of knowledge as well as the awareness and acceptance of electric drive and other advanced technology vehicles (ATV). The AVTA accomplishes this goal by testing ATVs on test tracks and dynamometers (Baseline Performance testing), as well as in real-world applications (Fleet and Accelerated Reliability testing and public demonstrations). This enables the AVTA to provide Federal and private fleet managers, as well as other potential ATV users, with accurate and unbiased information on vehicle performance and infrastructure needs so they can make informed decisions about acquiring and operating ATVs. The ATVs currently in testing include vehicles that burn gaseous hydrogen (H2) fuel and hydrogen/CNG (H/CNG) blended fuels in internal combustion engines (ICE), and hybrid electric (HEV), urban electric, and neighborhood electric vehicles. The AVTA is part of DOE's FreedomCAR and Vehicle Technologies Program.

Alternative Air Conditioning Technologies: Underfloor AirDistribution (UFAD) (open access)

Alternative Air Conditioning Technologies: Underfloor AirDistribution (UFAD)

Recent trends in today's office environment make it increasingly more difficult for conventional centralized HVAC systems to satisfy the environmental preferences of individual officer workers using the standardized approach of providing a single uniform thermal and ventilation environment. Since its original introduction in West Germany during the 1950s, the open plan office containing modular workstation furniture and partitions is now the norm. Thermostatically controlled zones in open plan offices typically encompass relatively large numbers of workstations in which a diverse work population having a wide range of preferred temperatures must be accommodated. Modern office buildings are also being impacted by a large influx of heat-generating equipment (computers, printers, etc.) whose loads may vary considerably from workstation to workstation. Offices are often reconfigured during the building's lifetime to respond to changing tenant needs, affecting the distribution of within-space loads and the ventilation pathways among and over office partitions. Compounding this problem, there has been a growing awareness of the importance of the comfort, health, and productivity of individual office workers, giving rise to an increased demand among employers and employees for a high-quality work environment. During recent years an increasing amount of attention has been paid to air distribution systems that …

Alternative Ionization Methods for Particle Mass Spectrometry (open access)

Alternative Ionization Methods for Particle Mass Spectrometry

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 rely on delayed ionization of ablated/desorbed neutral species so that ionization of target substances occurs after most of the expansion collisions have taken place. Resonance ionization by a tunable pulsed laser permits selective ionization of target species, with the laser tuned to a resonance transition from the ground state to an excited state of the target. Additional photons of the same (when possible) or different energy make up the energy required for ionization. The other approach is to perform the laser ablation step within a discharge so that desorbed neutrals are ionized by reactions with the plasma. Electron capture generates negative ions of substances with high electron affinity while electron impact ionization, associative ionization, and Penning ionization from excited metastable species produce positive ions in the discharge. Both atmospheric pressure Corona discharge …

Alternative Ultrafiltration Membrane Testing for the SRS Baseline Process (open access)

Alternative Ultrafiltration Membrane Testing for the SRS Baseline Process

The ability to more rapidly process high-level waste sludge and supernate, without sacrificing cost savings, continues to be a crucial challenge facing the Savannah River Site (SRS). There has, to date, not been any extensive investigation of alternative filter technologies for the SRS baseline process. To address this problem, a focused investigation into alternative, state-of-the art filtration technologies to facilitate the strontium and actinide removal process, which can be cost effectively implemented in existing facilities and current equipment designs, was completed. Filter technologies manufactured by Mott (0.1 µm and 0.5 µm) Graver (0.07 µm), Pall (0.1 µm and 0.8 µm) and GKN (0.1 µm) were evaluated. Membranes had a nominal inside diameter of 3/8 inches and an active membrane length of 2 feet. The investigation was performed in two phases. The first phase of testing evaluated the consistency or variability in flux through the different membranes using water and a standard 5.0 wt% strontium carbonate slurry. The second phase of testing evaluated the achievable permeate flux and clarity through the various membranes using the SRS average salt supernate simulant at solids loadings of 0.06, 0.29 and 4.5 wt%. Membrane variation data indicate that membranes having an asymmetric ceramic coating (Pall …

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

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

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 model the real time intensity of cesium produced Compton scattering. A successful research program will provide the fundamental information needed to design and develop advanced Compton spectrometers for assay of remote handled waste and new higher sensitivity spectrometers for environmental measurements.

The Aqueous Thermodynamics and Complexation Reactions of Anionic Silica and Uranium Species to High Concentration (open access)

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

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 composition of the leaking solutions, transforming them from a highly basic (as high 2M NaOH) solution into a pore solution with a very high concentration of dissolved silica and a significantly reduced pH. This moderately basic (pH 9 to 11), high-silica solution has the potential to complex radionuclides and move through the subsurface. Such strong radionuclide complexation is a currently unconsidered transport vector that has the potential to expedite radionuclide transport through the vad ose zone. These strong complexation effects have the ability to significantly alter current conceptual models of contaminant migration beneath leaking tanks. In this project, we are determining the aqueous thermodynamics and speciation of dissolved silica and silica-radionuclide complexes to high silica concentration. We are also initiating studies of U(VI) speciation …
