Application of magnetomechanical hysteresis modeling of magnetic techniques for monitoring neutron embrittlement and biaxial stress
Research was done on the biaxial stress problem accomplished in the first half of the second year. All of the work done was preparatory to magnetic measurements. Issues addressed were: construction of a model for extracting changes in the magnetic properties of a specimen from the readings of an indirect sensor; initial development of a model for how biaxial stress alters the intrinsic magnetic properties of thespecimen; use of finite element stress analysis modeling to determine a detailed shape for the cruciform biaxial stress specimen; and construction of the biaxial stress loading apparatus.

Application of magnetomechanical hysteresis modeling of magnetic techniques for monitoring neutron embrittlement and biaxial stress
Objective of this project is to investigate experimentally and theoretically the effects of neutron embrittlement and biaxial stress on magnetic properties in steels, using various magnetic measurement techniques. If neutron embrittlement and biaxial stress can be measured via changes in magnetic properties, this should ultimately assist in safety monitoring of nuclear power plants and of gas and oil pipelines. This first-year report addresses the issue of using magnetic property changes to detect neutron embrittlement. The magnetic measurements were all done on irradiated specimens previously broken in two in a Charpy test to determine their embrittlement. The magnetic properties of the broken charpy specimens from D.C. Cook did not correlate well with fluence or embrittlement parameters, possible due to metallurgical reasons. correlation was better with Indian Point 2 specimens, with the nonlinear harmonic amplitudes showing the best correlation (R[sup 2][approximately]0.7). However, correlation was not good enough. It is recommended that tests be done on unbroken irradiated Charpy specimens, for which magnetic characterization data prior to irradiation is available, if possible.

Control of triacylglycerol biosynthesis in plants
Seeds of most species of the Umbelliferae (Apiaciae), Araliaceae, and Garryaceae families are characterized by their high content of the unusual C[sub 18] monounsaturated fatty acid petroselinic acid (18:l[Delta][sup 6cis]). Prior to a recent report of this lab, little was known of the biosynthetic origin of the cis[Delta][sup 6] double bond of petroselinic acid. Such knowledge may be of both biochemical and biotechnological significance. Because petroselinic acid is potentially the product of a novel desaturase, information regarding its synthesis may contribute to an understanding of fatty acid desaturation mechanisms in plants. Through chemical cleavage at its double bond, petroselinic acid can be used as a precursor of lauric acid (12:0), a component of detergents and surfactants, and adipic acid (6:0 dicarboxylic), the monomeric component of nylon 6,6. Therefore, the development of an agronomic source of an oil rich in petroselinic acid is of biotechnological interest. As such, studies of petroselinic acid biosynthesis may provide basic information required for any attempt to genetically engineer the production and accumulation of this fatty acid in an existing oilseed.

Development and use of an apparatus to measure the dynamic surface properties of coal-water slurry fuels for applications to atomization characteristics
The Texas A M University (TAMU) has been awarded a DOE contract to study dynamic properties and atomization characteristics of coal-water slurry (CWS) fuels. Additives are essential for better mixing and stable suspension of coal powders and these additives change CWS properties. Dynamic properties will have major effects on CWS fuel atomization, which constitutes highly dynamic processes, and will determine the combustion as well as the pollutant formation behaviors. The dynamic surface tension of CWS fuels can be much higher than the corresponding static surface tension. Experimental study of correlating the atomization characteristics and dynamic properties of CWS fuels will be performed during the contract period. The research projects consists of five tasks. Task 1 selects appropriate additives and surfactants for CWS fuels by measuring the stabilizing characteristics and critical micelle concentrations (CMC). Task 2 implements the dynamic surface tensiometer operating based on the formation of maximum bubble pressure. Task 3 measures dynamic properties of CWS fuels as functions of bubble frequency while the fuel parameters are varied. The fuel parameters include coal loading, type of stabilizer and type of surfactant. Task 4 will devise a CWS fuel spray system and Task 5 will measure the spray droplet sizes using …

Lead macro-encapsulation conceptual and experimental studies
Macro-encapsulation, the regulatory treatment for radioactively contaminated lead (mixed) waste has been conceptually and experimentally evaluated for practical application. Epoxy encapsulants molded around lead billets have proven to be exceptionally rugged, easily applied, have high radiation and chemical stability, and minimize required process equipment and production of secondary wastes. This technology can now be considered developed, and can be applied as discussed in this report.

Research program on fractured petroleum reservoirs. Fourth quarterly report, October 1--December 31, 1993
Progress reports are presented for project 2-supersaturation, critical saturation and residual gas saturation in porous media and for project 5-simulation of fractured reservoirs. Under project 2, a visual high-pressure core-holder has been designed and constructed to be used in critical gas saturation and some other measurements. The apparatus has been used to measure critical gas saturation for a low viscosity mixture. These measurements reconfirm the investigators` previously published data that critical gas saturation for low viscosity fluids are low-around 1 percent. The apparatus is being currently used to measure critical gas saturation of an 11 API oil. Unlike light oils, heavy oil reservoirs, especially fractured heavy oil reservoirs might have an extremely high recovery efficiency with solution gas-drive. The critical gas saturation is an important element of recovery efficiency for such reservoirs.

Theoretical studies of surface reactions on metals and electronic materials
Studies of a variety of adsorbates on Ni have been completed; adsorption energies were determined for CH, CH[sub 2], CH[sub 3], H, NH[sub 3], H[sub 2]O, and C[sub 6]H[sub 6] on Ni(111). A refined calculation of the reaction of methane with Ni was completed. Other studies included H[sub 2] and SiH[sub 4] adsorption/decomposition on Si surfaces, Si-Si dimer bond length, activity energy barriers for reaction of CH[sub 4]and CH[sub 3]F with Si(111). Studies were begun on deposition of C on Ni(111). New directions were explored for reaction of methane with transition metal surfaces; work was completed for a Ni(111) surface containing a substitutional iron atom. Twenty abstracts of papers are presented.
