A Novel Treatment for Acid Mine Drainage Utilizing Reclaimed Limestone Residual

Description: The viability of utilizing Reclaimed Limestone Residual (RLR) to remediate Acid Mine Drainage (AMD) was investigated. Physical and chemical characterization of RLR showed that it is composed of various minerals that contain significant quantities of limestone or calcium bearing compounds that can be exploited for acid neutralization. Acid Neutralization Potential (ANP) test results showed that RLR has a neutralization potential of approximately 83% as calcium carbonate (CaCO{sub 3}). Neutraliza… more

Geomechanical Performance of Hydrate-Bearing Sediments in Offshore Environments

Description: The main objective of this study is to develop the necessary knowledge base and quantitative predictive capability for the description of geomechanical performance of hydrate bearing sediments (hereafter referred to as HBS) in oceanic environments. The focus is on the determination of the envelope of hydrate stability under conditions typical of those related to the construction and operation of offshore platforms. To achieve this objective, we have developed a robust numerical simulator of hyd… more

Innovative Structural and Joining Concepts for Lightweight Design of Heavy Vehicle Systems

Description: Recent advances in the area of Metal Matrix Composites (MMC's) have brought these materials to a maturity stage where the technology is ready for transition to large-volume production and commercialization. The new materials seem to allow the fabrication of higher quality parts at less than 50 percent of the weight as compared to steel, especially when they are selectively reinforced with carbon, silicon carbide, or aluminum oxide fibers. Most of the developments in the MMC materials have been … more

Fluidized Bed Steam Reformed Mineral Waste Forms: Characterization and Durability Testing

Description: Fluidized Bed Steam Reforming (FBSR) is being considered as a potential technology for the immobilization of a wide variety of high sodium low activity wastes (LAW) such as those existing at the Hanford site, at the Idaho National Laboratory (INL), and the Savannah River Site (SRS). The addition of clay, charcoal, and a catalyst as co-reactants with the waste denitrates the aqueous wastes and forms a granular mineral waste form that can subsequently be made into a monolith for disposal if neces… more

Solubility modeling of refrigerant/lubricant mixtures

Description: A general model for predicting the solubility properties of refrigerant/lubricant mixtures has been developed based on applicable theory for the excess Gibbs energy of non-ideal solutions. In our approach, flexible thermodynamic forms are chosen to describe the properties of both the gas and liquid phases of refrigerant/lubricant mixtures. After an extensive study of models for describing non-ideal liquid effects, the Wohl-suffix equations, which have been extensively utilized in the analysis o… more

Corrosion Analysis: Low-Capacity Pump. Large Sodium Pump Study, Phase II.

Description: An evaluation was made of the effect of sodium on the integrity of the pump materials identified in the Large Pump Study Phase I. There were 304 stainless steel as the constructional material and Stellites 1, 3 and Star J as potential bearing materials. These materials have been evaluation for use under expected pump operating conditions. Relevant data on sodium corrosion, the effect of sodium on mechanical properties and the effect of temperature on mechanical properties have been reviewed and… more

RADIOISOTOPE FUELED AUXILIARY POWER UNIT. Quarterly Progress Report No. 6, April 1958-July 1958

Description: A modular concept has evolved which permits testing of SNAP-1 as an attachable unit. Integrity testing of fuel elements in simulated pad aborts is reported. The adequacy of a full-scale boiler mockup in vaporizing mercury at the design point was tested; a new boiler coil designed to prevent slugging was tested. The sintering properties of CeO/sub 2/ were further investigated. Dynamic mercury corrosion testing of Croloy 5 Si and Croloy 5 Ti is reported. Static lead tests of CeO/sub 2/ pellets, b… more

DEVELOPMENT OF PLUTONIUM-BEARING FUEL MATERIALS. Progress Report, July 1 through September 30, 1962

Description: Characterization and sintering results indicate significant differences between UO/sub 2/--35 wt% PuO/sub 2/ and the compositions containing lesser (<20 wt %) amounts of PuO/sub 2/. PuO/sub 2/ has now also been prepared by plutonium hydroxide precipitation. Sintering studies have shown that satisfictory density is readily attained with these PuO/sub 2/ materials. Development of analytical chemistry procedures required for support of the fuel cycle program is continuing. The x-ray emission proce… more

Current leads and magnetic bearings

Description: Since the discovery of high-temperature superconductors (HTSs), Argonne National Laboratory (ANL) has been active in a broad spectrum of activities in developing these materials for applications. Work at every stage of development has involved industrial collaboration in order to accelerate commercialization. While most of the development work has been devoted to improving the properties of current-carrying wires, some effort has been devoted to applications that can utilize HTSs with propertie… more

Horizontal Air Bearing Experiment Number 1

Description: The Horizontal Air Bearing Experiment No.1 is a series of tests intended to further the understanding of rotational dynamics. A simple experimental assembly is rotated using the Horizontal Air Bearing and allowed to spin freely as the internal rotational damping is measured. The low friction of the bearing effectively isolates the test assembly, allowing the internal damping of the test object to be evaluated. The experimental assembly is composed of an aluminum ball within a spherical cavity. … more
