Theoretical atomic collision physics
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 alignment of the initial electron charge distribution (for non-spherical initially excited states). (2) We wish to understand how characteristics of the classical trajectories (in CTMC calculations), e.g. multiple encounters, quasi-periodicity, chaos, relate to characteristics of the probability (scattering) amplitudes obtained from semiclassical (quantum mechanical) treatments. (3) In particular, in order to investigate a range of interaction regimes,'' we have proposed to study low-Rydberg-atom collisions with: ions and polar molecules (long range interaction); non-polar molecules and atoms (short-range interaction); as well as electron-attaching atoms/molecules (transient electron capture possible). (4) We plan to look for observable signatures of possibly novel intracollisional interference effects and quasi-vibrational resonance effects that may occur in low-Rydberg collisions.

Fundamental mechanisms in flue gas conditioning
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 the project is designed to determine how ash particles are modified by interactions with sorbent injection processes and to describe the mechanisms by which these interactions affect fine particle collection. The objective of the other part of the project is to identify the mechanisms by which conditioning agents, including chemically active compounds, modify the key properties of fine fly ash particles.

Chemical and thermal stability of refrigerant-lubricant mixtures with metals
This report presents the results of a sealed tube stability study on twenty-one refrigerant-lubricant mixtures selected from the following groupings: HFCs R-32, R-125, R-134, R-134a, R-143a, and R-152a with one or more lubricants selected from among three pentaerythritol esters and three polyalkylene glycols. All lubricants were carefully predried to 25 ppm or less moisture content. HCFCs R-22, R-123, R-124, and R-142b, as well as CFC R-11, with one or more lubricants selected from among two mineral oils and one alkylbenzene fluid. Bach test mixture was aged at three temperature levels.

Steam explosion analysis in support of the SRS reactor safety assessment
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 are that hot molten material come into contact with water, and that the material's temperature be high enough to both support film boiling at its surface, and remain molten until an explosion is initiated. In a number of PRA accident sequences, aluminum-uranium debris will be hot enough to participate in a steam explosion. The high pressure vapor produced, the shock waves, and the kinetic energy of material can all do destructive work on structures surrounding the explosion site. Fuel melting is possible during several postulated severe accident scenarios for the SRS reactors. In many cases, water will exist in the reactor primary system and/or on the confinement building floor. Steam explosions must be characterized by a few significant parameters that can be addressed in the PRA. …

A comparison of reverse osmosis membrane cleaning methods
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) cleaning methods with sequential cleanings using NAOH and Filmtec Alkaline Cleaner. The importance of the cleaning sequence with these two chemicals was also examined.

The NHMFL 60 tesla, 100 millisecond pulsed magnet
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 will be needed for the higher field quasi-stationary pulsed magnets that this power source is capable of driving. This report will discuss specifications and parameters of this magnet.

Uranium in the Savannah River Site environment
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 reports have been published since 1963. Occasionally unpublished data are included in this report for completeness.
