A Review of Information for Managing Aging in Nuclear Power Plants

Description: Age related degradation effects in safety related systems of nuclear power plants should be managed to prevent safety margins from eroding below the acceptable limits provided in plant design bases. The Nuclear Plant Aging Research (NPAR) Pro- gram, conducted under the auspices of the U.S. Nuclear Regulatory Commission (NRC), Office of Nuclear Regulatory Research, and other related aging management programs are developing technical information on managing aging. The aging management process cen… more

Soft Contribution to Form Factors of Gamma<sup>*</sup> p -> Delta<sup>+</sup> Transition

Description: The purely nonperturbative soft contribution to the gamma<sup>*</sup> p -> delta<sup>+</sup> transition form factors is estimated using the local quark-hadron duality approach. Our results show that the soft contribution is dominated by the magnetic transition: the ratio G<sup>*</sup> <sub>E</sub> Q<sup>2</sup>/ G<sup>*</sup><sub>M</sub> Q<sup>2</sup> is small for all accessible Q<sup>2</sup>, in contrast to pQCD expectations that G<sup>*</sup><sub>E</sub> (Q<sup>2</sup>) -> -G<sup>*</sup><sub>… more

Next Generation Geothermal Power Plants

Description: A number of current and prospective power plant concepts were investigated to evaluate their potential to serve as the basis of the next generation geothermal power plant (NGGPP). The NGGPP has been envisaged as a power plant that would be more cost competitive (than current geothermal power plants) with fossil fuel power plants, would efficiently use resources and mitigate the risk of reservoir under-performance, and minimize or eliminate emission of pollutants and consumption of surface and g… more

Science and technology review, September 1995

Description: This report describes efforts to identify the metabolic pathways of heterocyclic amines in animals and humans. These heterocyclic amines are potent mutagens when foods derived from muscle and other protein sources are cooked. Attempts have been made to study the effects of these toxic compounds on DNA. Attention is focused on the potential cancer risks associated with their intake as food.

Colorado State University Program for Developing, Testing, Evaluating, and Optimizing Solar Heating and Cooling Systems. Project Status Report, June 1994--July 1994

Description: This report describes integrated tank/heat exchanger modeling and experiments. Experiments were performed on a Rheem wrap-around 80 gallon electric hot water heater tank with the bottom heating element replaced by a 120 feet long coil of copper tubing wrapped around the outside lower half of the tank. The bottom two-thirds of the tank is heated by hot antifreeze circulating from the solar collector through the copper coil. Results are discussed.

Improving the diversity of manufacturing electroluminescent flat panel displays

Description: Crystalline calcium thiogallate with a cerium dopant has been deposited by metal-organic chemical vapor deposition (MOCVD) at temperatures below 600{degrees}C on a low cost glass substrate. An EL luminance of 1.05 fL was observed 40 volts above threshold at 60 Hz. This is more than an order of magnitude improvement over earlier crystalline-as-deposited thiogallate materials. These results pave the way for the use of MOCVD as a potential method for processing full color thin-film electroluminesc… more

Experimentally validated computational modeling of organic binder burnout from green ceramic compacts

Description: The properties and performance of a ceramic component is determined by a combination of the materials from which it was fabricated and how it was processed. Most ceramic components are manufactured by dry pressing a powder/binder system in which the organic binder provides formability and green compact strength. A key step in this manufacturing process is the removal of the binder from the powder compact after pressing. The organic binder is typically removed by a thermal decomposition process … more

Study of multicomponent diffusion and transport phenomena. Technical report, July 1, 1984--June 30, 1995

Description: This progress report summarizes a project to treat the diffusion and transport phenomena in multicomponent systems from an atomistic point of view mainly by means of a kinetic method based on the Cluster Variation Method (CVM)-Path Probability Method (PPM) formalism. As is well known, the CVM has established itself as one of the most systematic methods of statistical thermodynamics, and macroscopic phenomena treated by thermodynamics can thus be investigated atomistically in great detail. The a… more

The neutron physics of concrete reflectors

Description: It has long been known that concrete reflection can be an important factor in determining the critical state of any fissile system, single unit or storage array. Since there can be a large variation in the chemical makeup of concrete, mass-limit reduction factors are necessarily conservative, and may lead to a very uneconomical storage arrangement. This study was undertaken to clarify the importance of the various concrete constituents and to determine some general guidance as to the magnitude … more

Responsive copolymers for enhanced petroleum recovery. Quarterly progress report, March 21, 1995--June 22, 1995

Description: Advanced polymer systems that possess microstructural features that are responsive to temperature, electrolyte concentration, and shear conditions are being synthesized which will be superior to polymers presently used for mobility control in enhanced oil recovery. Improved polymer performance is accomplished by controlling hydrophobic or ampholytic interactions between individual polymer chains in solution. Of special interest to our group have been (1) the elucidation of the mechanism of asso… more

Combustion fume structure and dynamics. Semiannual report, February 16, 1993--August 15, 1993

Description: During pulverized coal combustion, a fume of submicron particles is formed from the mineral matter in the parent coal. Studies of the variation in chemical composition with particle size have revealed that much of the submicron fume is formed from volatilized coal ash. The formation and evolution of the ash fume is governed by homogeneous nucleation, condensation, and coagulation. Vapors of refractory species nucleate relatively early in the combustion process. Coagulation of those fine particl… more
