This report presents field results and raw data from the Buried Waste Integrated Demonstration (BWID) Arc Melter Vitrification Project Phase 1 baseline test series conducted by the Idaho National Engineering Laboratory (INEL) in cooperation with the U.S. Bureau of Mines (USBM). The baseline test series was conducted using the electric arc melter facility at the USBM Albany Research Center in Albany, Oregon. Five different surrogate waste feed mixtures were tested that simulated thermally-oxidized, buried, TRU-contaminated, mixed wastes and soils present at the INEL. The USBM Arc Furnace Integrated Waste Processing Test Facility includes a continuous feed system, the arc melting furnace, an offgas control system, and utilities. The melter is a sealed, 3-phase alternating current (ac) furnace approximately 2 m high and 1.3 m wide. The furnace has a capacity of 1 metric ton of steel and can process as much as 1,500 lb/h of soil-type waste materials. The surrogate feed materials included five mixtures designed to simulate incinerated TRU-contaminated buried waste materials mixed with INEL soil. Process samples, melter system operations data and offgas composition data were obtained during the baseline tests to evaluate the melter performance and meet test objectives. Samples and data gathered during this program included …

This paper addresses a new value engineering approach successfully being used at the Idaho National Engineering Laboratory (INEL) in the design process of major construction projects. Of particular interest is how value engineers are applying the principles of Total Quality Management (TQM), utilizing value engineering techniques. Discussed are the associated problems with how major construction projects were previously planned, designed, value engineered, and then redesigned. Benefits of applying value engineering techniques early-on in the design process, far ahead of the traditional time for VE execution, is examined. The author provides a pro-con analysis of the benefits of early-on value engineering effort, and uses data gathered from several value engineering studies to support the conclusions of this paper.

Using first-principles electronic structure calculations based on the Linear-Muffin-Tin Orbital (LMTO) method, we have investigated the effects of interstitial born and hydrogen on the electronic structure of the Ll{sub 2} ordered intermetallic Ni{sub 3}Al. When it occupies an octahedral interstitial site entirely coordinated by six Ni atoms, we find that boron enhances the charge distribution found in the strongly-bound ``pure`` Ni{sub 3}Al crystal: Charge is depleted at Ni and Al region. Substitution Al atoms for two of the Ni atoms coordinating the boron, however, reduces the interstitial charge density between atomic planes. In contrast to boron, hydrogen appears to deplete the interstitial charge, even when fully coordinated by Ni atoms. We suggest that these results are broadly consistent with the notion of boron as a cohesion enhancer and hydrogen as an embrittler.

This paper describes ductile-phase roughening in V-V{sub 3}Si in-situ composites produced by conventional arc melting (AM), cold-crucible induction melting (IM), and cold-crucible directional solidification (DS). Notched three-point bending tests were performed to determine the effects of synthesis method on the room temperature fracture toughness of eutectic compositions, which contain nearly equal volume fractions of V{sub 3}Si and the V(Si) solid solution phase. Fracture toughness values ranged from 10 MPa{radical}m for the AM eutectic to over 20 MPa{radical}4m for the IM and DS eutectic alloys. SEM fractography, surface profiling, and chemical analyses were performed to correlate the toughness values with the microstructures and interstitial concentrations produced by the three synthesis methods.

A laser flash photolysis kinetic study of a W(CO){sub 5} intermediate reacting with several different substituted 2,2{prime}-bipyridine ligands at pressures up to 150 MPa in liquid toluene has confirmed the considerable influence of steric hindrance on the mechanism of a thermal ring closure reaction. A similar laser flash photolysis kinetic study has been carried out with Mo(CO){sub 6} and several bidentate ligands resembling 2,2{prime}-bipyridine dissolved in supercritical carbon dioxide. A much larger negative activation volume is found in supercritical carbon dioxide than observed previously with this solute system dissolved in liquid toluene. Rate of replacement of one polydentate ligand by another stronger chelating agent in the first coordination sphere of aqueous gadolinium(III) ion was measured over a range of pressures and other variables using a stopped-flow spectrophotometer. Two consecutive first order reaction steps are observed that show acid-catalysis.

A numerical model, TOUGH2, was selected for describing liquid- and gas-phase flow in the unsaturated tuff underlying the TA-73 landfill. The model was selected primarily for its ability to simulate the significant mechanisms that may affect transport of contaminants through the vadose zone at the TA-73 landfill, including non-isothermal flow through fractured media. TOUGH2 is the best documented, verified, and validated model capable of performing the required simulations. The sensitivity analyses that were performed and describes in this report identified the input parameters that the selected numerical model is most sensitive to. The input parameters analyzed were saturated hydraulic conductivity, van Genuchten {alpha} and n, residual and saturated moisture contents, infiltration rate, fracture spacing and permeability, atmospheric pressure, and temperature. The sensitivity analyses were performed using a model grid that was designed to incorporate the regions in the landfill vicinity where contaminant transport is likely to occur and where the physical processes affecting flow and transport are the most dynamic. The sensitivity analyses performed suggest that the model is quite sensitive to a number of input parameters, including saturated hydraulic conductivity, the van Genuchten parameters {alpha} and n (for both the tuff matrix and fractures), fracture density and aperture, and …

Fully dense, nanocrystalline ceramic articles were prepared by a new nanofabrication process. The process consists of two steps: synthesis of ceramic nanoparticles and fabrication of dense, nanocrystalline ceramic parts. The synthesis step produced 10-nanometer-diameter crystallites, and is capable of being scaled up to kilogram/hour production rates. The fabrication step produced dense parts at significantly reduced sintering temperatures and times--representing a factor of 10--100 reduction in process energy requirements. Process was demonstrated by producing ultrafine-grained yttria-stabilized ZrO{sub 2}, an important material with a variety of energy-related applications (e.g., solid electrolytes, oxygen sensors, electrode materials, thermal barrier coatings, etc.). Results from this period illustrate capabilities of this energy-efficient and directly commercializable process for producing dense, nanocrystalline, multicomponent oxide ceramics.

This paper discusses the physics and chemistry of non-thermal plasma processing for post-combustion NO{sub x} control in internal combustion engines. A comparison of electron beam and electrical discharge processing is made regarding their power consumption, radical production, NO{sub x} removal mechanisms, and by product formation. Can non-thermal deNO{sub x} operate efficiently without additives or catalysts? How much electrical power does it cost to operate? What are the by-products of the process? This paper addresses these fundamental issues based on an analysis of the electron-molecule processes and chemical kinetics.

The objectives of this project are to study the effect of pretreatment methods on the two-stage liquefaction process. In particular, the effects of dispersed catalysts and carbon monoxide atmospheres on a coal liquefaction process. The project is divided into three technical tasks. Task 1 involves the analyses of the liquefaction products derived from liquefaction experiments using the catalysts Fe(CO){sub 5} and the sulfated iron catalyst, Fe{sub 2}O{sub 3}{center_dot}SO{sub 4}. We also analyzed the products derived from treating the recycle vehicle under coal liquefaction conditions with no coal or catalyst present, and found that the toluene and THF fractions had low H/C ratios. No CO or CO{sub 2} gases were detected after reaction, although considerable amount of methane gas was produced, suggesting that during the liquefaction runs the carbon oxides are produced only from the coal, as expected, but that methane gas is produced both from the recycle solvent and the coal. We now have more information about the recycle solvent from Wilsonville, who report that the residue was 63%, composed of 45% resid and 18% insoluble inorganic (CI), and a distilable portion of 37% (1050{degrees}F). During this quarter we compared coal conversions using Fe(CO){sub 5} with CO and H{sub 2}/CO …

A goal of chemical reaction dynamics is to control the course of reactions. We are examining the photodissocation of HOD, which is attractive for coherent control studies. A fixed frequency laser at 600 nm and its third harmonic at 200 nm is used to simultaneously and coherently photodissociate the rovibrationally excited parent molecules. Preliminary experiments focussed on confirming individual steps of the complex experiment; results are given of three-photon dissociation of H{sub 2}O, which gives confidence for the HOD three-photon dissociation.

The United States Department of Energy, Morgantown Energy Research Center (DOE/METC), is sponsoring the development of direct coal-fired turbine power plants as part of their Heat Engines program. A major technical challenge remaining for the development of the direct coal-fired turbine is high-temperature combustion gas cleaning to meet environmental standards for sulfur oxides and particulate emissions, as well as to provide acceptable turbine life. The Westinghouse Electric Corporation, Science & Technology Center, is evaluating two Integrated Low Emissions Cleanup (ILEC) concepts that have been configured to meet this technical challenge: A baseline ceramic barrier filter ILEC concept, and a fluidized bed ILEC concept. These ILEC concepts simultaneously control sulfur, particulate, and alkali contaminants in the high-pressure combustion gases at turbine inlet temperatures up to 2300{degrees}F. This document reports the status of a program in the nineteenth quarter to develop this ILEC technology for direct coal-fired turbine power plants.

This document is the Software Configuration Management Plan (SCMP) for the Federal Emergency Management Information System (FEMIS) project. FEMIS is an automated decision support system that integrates the planning and analysis, operations and response, and recovery phases of emergency management. It has broad application across the full range of emergency planning and operations. The SCMP will describe the configuration management system to be used for the control and maintenance of the software and associated documentation during development, test, and production of the FEMIS project. This plan provides information on the requirements and procedures necessary for the configuration management activities of FEMIS. It identifies the software configuration management requirements and establishes the methodology for generating configuration identifiers, controlling engineering changes, maintaining status accounting, and performing audits and reviews during the design and development of software configuration items. This plan defines the Software Configuration Management (SCM) activities necessary for maintaining all support software items and associated documentation being developed, procured, tested, sustained and kept in the production environment for FEMIS. It will apply to all phases of the software development life cycle, up to and including the time of delivery to the customer.

In recognition of the role of plants in the bio-geosphere carbon cycle, the Department of Energy (OHER) initiated a research program: The Direct Effects of Increasing Carbon Dioxide on Vegetation. This report describes the continuing research that we are conducting as part of this program. The ultimate goal of our research is to develop computer models capable of predicting responses of plants and ecosystems to the direct and indirect effects of atmospheric levels of carbon dioxide that are approximately twice those of the preindustrial period. The understanding of ecosystem responses to elevated CO{sub 2} necessarily depends on knowledge of responses of individual plants and their interactions with one another and their environment Our research approach incorporates the study and modeling of response to CO{sub 2} at all levels of the plant-community-ecosystem hierarchy, in an effort to understand the linkages and translation of effects of CO{sub 2} from one level to another. The research results reported here focus at several different levels of this hierarchy, and are highlights of accomplishments for the period September 1992 to June 1993.

The authors analyze the consequences of models of structure formation for higher-order (n-point) galaxy correlation functions in the mildly non-linear regime. Several variations of the standard [Omega] = 1 cold dark matter model with scale-invariant primordial perturbations have recently been introduced to obtain more power on large scales, R[sub p] [approximately]20 h[sup [minus]1] Mpc, e.g., low-matter-density (non-zero cosmological constant) models, [open quote]tilted[close quote] primordial spectra, and scenarios with a mixture of cold and hot dark matter. They also include models with an effective scale-dependent bias, such as the cooperative galaxy formation scenario of Bower, et al. The authors show that higher-order (n-point) galaxy correlation functions can provide a useful test of such models and can discriminate between models with true large-scale power in the density field and those where the galaxy power arises from scale-dependent bias: a bias with rapid scale-dependence leads to a dramatic decrease of the hierarchical amplitudes Q[sub J] at large scales, r [approx gt] R[sub p]. Current observational constraints on the three-point amplitudes Q[sub 3] and S[sub 3] can place limits on the bias parameter(s) and appear to disfavor, but not yet rule out, the hypothesis that scale-dependent bias is responsible for the extra power observed …
