Theoretical atomic collision physics

Description: The current focus of the research is low-energy (collision v<<bound v{sub e}) inelastic collisions for selected systems that possess the characteristic that many intermediate states are strongly coupled, such as can occur in classes of excited-atom (including Rydberg atom) collisions with atoms, molecules and positive and negative ions: (1) We are interested in the dependence of various differential and total cross sections on the angular momentum of the initial excited state and on the alignme… more

Fundamental mechanisms in flue gas conditioning

Description: The overall goal of this research project is to formulate a mathematical model of flue gas conditioning. This model will be based on an understanding of why ask properties, such as cohesivity and resistivity, are changed by conditioning. Such a model could serve as a component of the performance models of particulate control devices where flue gas conditioning is used. There are two specific objectives of this research project, which divide the planned research into two main parts. One part of … more

Steam explosion analysis in support of the SRS reactor safety assessment

Description: This report describes the application of two steam explosion models in support of the Probabilistic Risk Assessment (PRA) for the Savannah River Reactors. Theoretical models are required to estimate steam explosion yields in terms of kinetic energy, pressure shock and steam generated by the event. These quantities are used in the PRA to determine fission product barrier integrity in the reactor confinement following a hypothetical steam explosion. The basic preconditions for a steam explosion a… more

A comparison of reverse osmosis membrane cleaning methods

Description: Testing was conducted at TNX to evaluate the reverse osmosis (RO) cleaning methods in use at the F/H Effluent Treatment Facility (ETF). The present ETF membrane cleaning protocol involves a low-pressure-no-permeation method using NAOH. This work has examined the effectiveness of the present ETF method, due to the lack of improvement following the cleanings sometimes observed. This study has evaluated both low pressure (15--20 psi with no permeation) and high pressure (200 psi with permeation) c… more

The NHMFL 60 tesla, 100 millisecond pulsed magnet

Description: Among the new facilities to be offered by the National Science Foundation through the National High Magnetic Field Laboratory (NHMFL) are pulsed fields that can only be achieved at a national user facility by virtue of their strength, duration, and volume. In particular, a 44 mm bore pulsed magnet giving a 60 tesla field for 100 ms is in the final design stage. This magnet will be powered by a 1.4 GW motor-generator at Los Alamos and is an important step toward proving design principles that wi… more

Uranium in the Savannah River Site environment

Description: The purpose of this report is to consolidate the history of environmental uranium studies conducted by SRS and to describe the status of uranium in the environment. The report is intended to be a ``living document`` that will be updated periodically. This draft issue, February 1992, documents studies that occurred from 1954 to 1989. Data in this report are taken primarily from annual and semiannual environmental reports for SRS. Semiannual reports were published from 1954 through 1962. Annual r… more

Mechanisms controlling the production and transport of methane, carbon dioxide, and dissolved solutes within a boreal peatland. Progress report, January 15, 1991--July 14, 1992

Description: Peatlands are one of the most important terrestrial reservoirs in the global cycle for carbon, and are a major source for atmospheric methane. However, little is known about the dynamics of these carbon reservoirs or their feedback mechanisms with the pool of atmospheric CO{sub 2} during the Holocene. Specifically, it is unknown whether large peat basins are sources, sinks, or steady-state reservoirs for the global carbon cycle. In particular, the production and transport of methane, carbon dio… more

Development and testing of industrial scale, coal fired combustion system, Phase 3. First quarterly technical progress report, Part 1, October 1, 1991--December 31, 1991; Part 2, January 1, 1992--March 31, 1992

Description: The primary objective of the present Phase 3 effort is to perform the final testing at a 20 MNBtu/hr commercial scale of an air cooled, slogging coal combustor for application to industrial steam boilers and power plants. The focus of the test effort will be on combustor durability, automatic control of the combustor`s operation, and optimum environmental control of emissions inside the combustor. In connection with the latter, the goal is to achieve 0.4 lb/MMBtu of SO{sub 2} emissions, 0.2 lb/… more

Multi-frame x-ray imaging with a large area 40ps camera

Description: The authors have developed a large area short pulse framing camera that is capable of sixteen frames and shutter times of 40ps per frame. This is accomplished with a high fidelity electrical circuit and a L/D = 20 microchannel plate, driven by a short pulse (80ps) high amplitude electrical driver. They show results of this work they have done to support this type of shutter time and the difficulties associated with large area high speed shuttering.

The effect of process parameters on the surface finish of plasma polymers

Description: The surface finish of plasma polymers deposited in an inductively coupled discharge were measured as a function of gas flow rates. Surface finish was measured both optically and by AFM. The process parameters of the plasma polymerization were found to effect the surface finish. The gases used were trans-2- butene and hydrogen for hydrocarbon polymers. For bromocarbon polymers we added ethylbromide. The smoothest hydrocarbon polymer coatings had an RMS surface finish better than 1 nm. Bumps 200 … more
