Nesting bird deterrents for the Federal Republic of Germany glass log storage pad (open access)

Nesting bird deterrents for the Federal Republic of Germany glass log storage pad

A proposed storage pad wi11 be constructed in the 200 West Area for the storage of isotopic heat and radiation sources from the Federal Republic of Germany. The pad will be constructed in the southern portion of the Solid Waste Operations Complex near the existing Sodium Storage Pad (Figure 1). Following a biological review by Pacific Northwest National Laboratory (PNNL) personnel (Brandt 1996), it was determined that in order for construction to take place after March 15, 1997, actions would need to be taken to prevent migratory birds from nesting in the project area. Special attention was focused on preventing sage sparrows and loggerhead shrikes, both Hanford Site species of concern (DOE/RL 1996), from nesting in the area. This activity plan details the methods and procedures that will be used to implement these nesting deterrents.

Molecular genetics of metal detoxification: Prospects for phytoremediation. 1997 annual progress report (open access)

Molecular genetics of metal detoxification: Prospects for phytoremediation. 1997 annual progress report

'The authors proposed to characterize a number of fission yeast mutants that are hypersensitivity to cadmium and deficient in the production of metal-peptide complexes. For each of the mutants the authors sought to clone the gene responsible for the mutant phenotype and more importantly to define the gene function. They summarize the progress made thus far for each of the mutants. Mutants that hypoproduce phytochelatins are: (1) DS12--The gene has been cloned, but a full length cDNA remains to be isolated. They believe the longest clone is short at the 5 feet end by less than 100 bp. This gene encodes sulfite reductase and its function is needed for Pb-induced sulfide production, but not Cd-induced sulfide production. Since this enzyme acts upstream of cysteine biosynthesis, the likely reason that this mutant hypoproduces phytochelatins is that it fails to produce sufficient cysteine during Cd stress. (2) JS563--The gene has been cloned and found to encode a sulfide dehydrogenase. In vitro, the authors found that the protein binds FAD, converts S{sup 2-} to S{sup 0} while reducing quinone. The protein is membrane associated and has been localized to the mitochondria. Its likely function is to detoxify sulfide in the mitochondria resulting from …

Synthesis report on thermally driven coupled processes (open access)

Synthesis report on thermally driven coupled processes

The main purpose of this report is to document observations and data on thermally coupled processes for conditions that are expected to occur within and around a repository at Yucca Mountain. Some attempt is made to summarize values of properties (e.g., thermal properties, hydrologic properties) that can be measured in the laboratory on intact samples of the rock matrix. Variation of these properties with temperature, or with conditions likely to be encountered at elevated temperature in the host rock, is of particular interest. However, the main emphasis of this report is on direct observation of thermally coupled processes at various scales. Direct phenomenological observations are vitally important in developing and testing conceptual models. If the mathematical implementation of a conceptual model predicts a consequence that is not observed, either (1) the parameters or the boundary conditions used in the calculation are incorrect or (2) the conceptual basis of the model does not fit the experiment; in either case, the model must be revised. For example, the effective continuum model that has been used in thermohydrology studies combines matrix and fracture flow in a way that is equivalent to an assumption that water is imbibed instantaneously from fractures into adjacent, partially …

Quantifying silica reactivity in subsurface environments: Reaction affinity and solute matrix controls on quartz and SiO{sub 2} glass. 1997 annual progress report (open access)

Quantifying silica reactivity in subsurface environments: Reaction affinity and solute matrix controls on quartz and SiO{sub 2} glass. 1997 annual progress report

'The author reports the preliminary results of the experiments on the dissolution behavior of vitreous silica (v-SiO{sub 2}) into aqueous solutions of variable pH and ionic strength. The experiments are being conducted in mixed flow reactors with a high circulation rate that simulates constant-stirred conditions, the efficacy of which the authors discuss below. The preliminary results indicate that v-SiO{sub 2} dissolves into aqueous solutions approximately two orders of magnitude more quickly than crystalline silica (e.g., quartz). With additional experiments, they will utilize the dissolution rate data as a framework for understanding the behavior of waste glass compositions in the subsurface. In other work related to the studies of glass reactivity, the author has written one book chapter that will be published as part of a proceedings for the CEA/VALRHO international nuclear waste disposal conference held in Mejannes le Clap, France. In separate work, she is presently writing a second book chapter for the volume entitled Adsorption on Silica Surfaces.'

Direct Aromaization of Methane (open access)

Direct Aromaization of Methane

The thermal decomposition of methane offers significant potential as a means of producing higher unsaturated and aromatic hydrocarbons when the extent of reaction is limited. Work in the literature previous to this project had shown that cooling the product and reacting gases as the reaction proceeds would significantly reduce or eliminate the formation of solid carbon or heavier (Clo+) materials. This project studied the effect and optimization of the quenching process as a means of increasing the amount of value added products during the pyrolysis of methane. A reactor was designed to rapidly quench the free-radical combustion reaction so as to maximize the yield of aromatics. The use of free-radical generators and catalysts were studied as a means of lowering the reaction temperature. A lower reaction temperature would have the benefits of more rapid quenching as well as a more feasible commercial process due to savings realized in energy and material of construction costs. It was the goal of the project to identify promising routes from methane to higher hydrocarbons based on the pyrolysis of methane.

The use of dielectric and NMR measurements to determine the pore-scale location of organic contaminants. 1997 annual progress report (open access)

The use of dielectric and NMR measurements to determine the pore-scale location of organic contaminants. 1997 annual progress report

'The objective of the three-year research project is to investigate the effect of adsorbed organics on the dielectric and nuclear magnetic resonance (NMR) response of porous geological materials. This will allow us to assess the use of dielectric and NMR measurements at a site to determine whether organic contaminants are present in the central volume of the pore space (in a water-wet system) or are adsorbed to the solid surface. In addition, the authors propose to use laboratory dielectric and NMR measurements to study the kinetics of the adsorption and desorption of organics by conducting experiments where the authors control temperature and vary fluid chemistry. This project can be divided into three parts: sample preparation, NMR studies, dielectric studies. Over the past nine months the authors have made significant progress in sample preparation and NMR studies. As the plan is to conduct the NMR and dielectric measurements on the same set of samples, the authors delayed the start of the dielectric measurements until the first stage of NMR measurements were complete. Below the authors summarize the progress in sample preparation and NMR measurements, first briefly introducing the method used for the NMR measurements.'

Engineering Development of Coal-Fired High-Performance Power Systems (open access)

Engineering Development of Coal-Fired High-Performance Power Systems

The concept uses a pyrolyzation process to convert coal into fuel gas and char. The char is fired in a High Temperature Advanced Furnace (HITAF). It is a pulverized fuel- fired boiler/ air heater where steam and gas turbine air are indirectly heated. The fuel gas generated in the pyrolyzer is then used to heat the gas turbine air further before it enters the gas turbine. The project is currently in Phase 2 which includes engineering analysis, laboratory testing and pilot plant testing. Research and development is being done on the HIPPS systems that are not commercial or being developed on other projects. Pilot plant testing of the pyrolyzer subsystem and the char combustion subsystem are being done separately, and then a pilot plant with a more integrated HIPPS arrangement will be tested. The High Performance Power System is a coal- fired, combined cycle power generating system that will have an efficiency of greater than 47 percent (HHV) with NOx and SOx less than 0.025 Kg/ GJ (0.06 lb/ MMBtu). This performance is achieved by combining a coal pyrolyzation process with a High Temperature Advanced Furnace (HITAF). The pyrolyzation process consists of a pressurized fluidized bed reactor which is operated …

Feedstock and Web Analysis Using Mid-Infrared Diffuse Reflectance Spectroscopy and Imaging Spectroradiometry (open access)

Feedstock and Web Analysis Using Mid-Infrared Diffuse Reflectance Spectroscopy and Imaging Spectroradiometry

Potential applications of mid-infrared (MIR) spectroscopy in the forest products industry include on-line analysis of feedstock and web materials; these applications differ dramatically in purpose, speed, and overall chemical heterogeneity. Characterization of feedstock will enable sorting of the stock and/or wet chemistry adjustment prior to the web stage of paper production. Sorting will require imaging of the stock as well as classification of the wide variety of chemistry found in recycled stock. At the opposite end of the manufacturing process, on-line analysis of the web will enable adjustment of machine parameters to maximize product quality and minimize waste. Spectroscopic requirements for web analysis include high-speed capability and measurement precision. If successful, both applications could result in a reduction of resource waste, a reduction of plant pollution, and a reduction of energy use while simultaneously improving product quality. Here the progress towards feedstock and web analysis with MIR spectroscopy is presented. To date, work has progressed in three main areas: Diffuse Reflectance mid-Infrared Fourier Transform (DRIFT) spectroscopy of cellulose-based materials, chemometrics analysis, and research of MIR instrumentation for prototype development. The DRIFT spectroscopy data represents a database of the chemistries and spectroscopic signatures of interest to the applications discussed here. Over …

Gyrokinetic theory for arbitrary wavelength electromagnetic modes in tokamaks (open access)

Gyrokinetic theory for arbitrary wavelength electromagnetic modes in tokamaks

A linear gyrokinetic system for arbitrary wavelength electromagnetic modes is developed. A wide range of modes in inhomogeneous plasmas, such as the internal kink modes, the toroidal Alfven eigenmode (TAE) modes, and the drift modes, can be recovered from this system. The inclusion of most of the interesting physical factors into a single framework enables one to look at many familiar modes simultaneously and thus to study the modifications of and the interactions between them in a systematic way. Especially, the authors are able to investigate self-consistently the kinetic MHD phenomena entirely from the kinetic side. Phase space Lagrangian Lie perturbation methods and a newly developed computer algebra package for vector analysis in general coordinate system are utilized in the analytical derivation. In tokamak geometries, a 2D finite element code has been developed and tested. In this paper, they present the basic theoretical formalism and some of the preliminary results.

Micro-agglomerate flotation for deep cleaning of coal. Final report (open access)

Micro-agglomerate flotation for deep cleaning of coal. Final report

The development of practical technologies for the deep cleaning of coal has been seriously hampered by the problems of carrying out efficient coal/mineral separations at the very fine sizes (often finer than 10 {micro}m) needed to achieve adequate liberation of the mineral matter from the coal matrix. In this investigation a hybrid process--Micro-agglomerate flotation--which is a combination of oil-agglomeration and froth flotation was studied. The basic concept is to use small quantities of oil to promote the formation of dense micro-agglomerates with minimal entrapment of water and mineral particles and to use froth flotation to separate these micro-agglomerates from the water/dispersed-mineral phase. Since the floating units will be relatively large agglomerates (30--50 {micro}m in size) rather than fine coal particles (1--10 {micro}m) the problems of froth overload and water/mineral carryover should be significantly alleviated. There are, however, complications. The process involves at least five phases: two or more solids (coal and mineral), two liquids (oil and water) and one gas (air). It is demonstrated in this study that the process is very sensitive to fluctuations in operating parameters. It is necessary to maintain precise control over the chemistry of the liquid phases as well as the agitation conditions in order …

FY 1996 cost savings report (open access)

FY 1996 cost savings report

Cost savings are an integral part of Hanford site operations. Congressional actions towards establishing a balanced budget have resulted in reductions to funding for all federal agencies, including the Department of Energy (DOE) Environmental Management (EM) cleanup mission. In September 1994 the DOE Richland Operations Office (RL) approved the FY 1995 multi-year baseline that included a cost estimate of $1.9 billion for FY 1996. However, Congress only appropriated $1.3 billion for that year. The shortfall of $600 million resulted in a significant challenge to accomplish the required workscope. Therefore, RL initiated an aggressive cost savings program to eliminate the shortfall by deleting workscope that was unnecessary and performing the remaining workscope more efficiently. RL initiated baseline planning actions (including deletions, deferrals, transfers, and additions) during the FY 1996 multi-year baseline development process to match workscope and anticipated funding and identified $205 million of workscope deletions. CFR (Contract Finance and Review Division) then reviewed over 200 cost baseline change requests during FY 1996 and documented an additional $95 million of FY 1996 cost savings. This included $73 million of workscope deletions and $22 million of efficiencies. Total savings as a result of FY 1996 initiatives, including baseline planning actions and current …
