Development of BEACON technology. Quarterly report, January-March 1982
The BEACON process involves the catalytic deposition of a highly reactive form of carbon from a gas stream which contains carbon monoxide. The carbon-depleted gas is combusted with air to produce power, and the carbon is reacted with steam to produce methane or hydrogen. Process conditions favoring the production of hydrogen were explored this quarter. Excess steam was found to suppress methane formation, and reduction of catalyst methanation activity was demonstrated. The effect of carbon loading on the physical stability of catalyst C77-K2 and the effect of trace sulfur levels on the chemical stability of the catalyst were examined. The carbon loading tests did not show the catalyst breakup that was expected. Tests of chemical stability of the catalyst in the presence of sulfur-containing gases showed a decline in performance even at levels as low as 4 ppM. Experiments conducted using a Paraho-type oil shale retort offgas as a feedstock showed that acceptable performance could be obtained by removing carbon dioxide from the feedgas. Design of the tandem two reactor system is continuing, along with cold flow testing of the proposed solids transfer system. A simplified thermodynamic analysis of the BEACON process shows that BEACON's increased efficiency over competing processes …

BACA Project: geothermal demonstration power plant. Final report
The various activities that have been conducted by Union in the Redondo Creek area while attempting to develop the resource for a 50 MW power plant are described. The results of the geologic work, drilling activities and reservoir studies are summarized. In addition, sections discussing the historical costs for Union's involvement with the project, production engineering (for anticipated surface equipment), and environmental work are included. Nineteen geothermal wells have been drilled in the Redondo Creek area of the Valles Caldera: a prominent geologic feature of the Jemez mountains consisting of Pliocene and Pleistocene age volcanics. The Redondo Creek area is within a complex longitudinal graben on the northwest flank of the resurgent structural dome of Redondo Peak and Redondo Border. The major graben faults, with associated fracturing, are geologically plausible candidates for permeable and productive zones in the reservoir. The distribution of such permeable zones is too erratic and the locations too imprecisely known to offer an attractive drilling target. Log analysis indicates there is a preferred mean fracture strike of N31W in the upper portion of Redondo Creek wells. This is approximately perpendicular to the major structure in the area, the northeast-striking Redondo Creek graben. The geothermal fluid found …

Ocean energy systems. Quarterly report, October-December 1982
Research progress is reported on developing Ocean Thermal Energy Conversion (OTEC) systems that will provide synthetic fuels (e.g., methanol), energy-intensive products such as ammonia (for fertilizers and chemicals), and aluminum. The work also includes assessment and design concepts for hybrid plants, such as geothermal-OTEC (GEOTEC) plants. Another effort that began in the spring of 1982 is a technical advisory role to DOE with respect to their management of the conceptual design activity of the two industry teams that are designing offshore OTEC pilot plants that could deliver power to Oahu, Hawaii. In addition, a program is underway in which tests of a different kind of ocean-energy device, a turbine that is air-driven as a result of wave action in a chamber, are being planned. This Quarterly Report summarizes the work on the various tasks as of 31 December 1982.

Physics Division Annual Review: 1 April 1981-31 March 1982
The research program in nuclear physics in the Argonne Physics Division contributes to most of the major questions in this scientific discipline. The development of the superconducting rf linac technology has led to the ATLAS project now under construction, and is the major focus of the effort in heavy-ion research. The investigation of pion interactions in nuclei using the LAMPF facility helps delineate the dominant aspects of pion propagation and interactions in nuclei. Experiments on the weak interaction in nuclei and on other fundamental symmetries are being carried out with a number of tools. The theoretical effort in nuclear structure, nuclear matter and dynamics, and reaction theory is closely coupled to many aspects of the experimental programs.

Fluidelastic Instability in Shell and Tube Heat Exchangers: A Framework for a Prediction Method
A framework for a method to predict fluid-elastic instability in heat exchanger tube bundles is presented. The method relies on a three-dimensional, cylindrical coordinate, thermal-hydraulic analysis code to obtain a representation of the three-dimensional flow distribution within the heat exchanger. With this information, local cross-flow velocities corresponding to each tube in the exchanger are obtained by interpolation and resultant cross-flow velocity distributions are computed. With a knowledge of the vibration mode shapes and frequencies, reduced effective cross-flow velocities are then computed for each tube. A comparison with experimental results shows excellent agreement: the tubes with high values of predicted reduced effective cross-flow velocity are the same tubes that first experience fluid-elastic instability in the flow tests and vibrate most violently; also, the simulation correctly predicts that the tubes directly exposed to the flow from the inlet nozzle have a low potential for fluid-elastic instability. Very good agreement is also shown in the comparison of the predicted reduced effective cross-flow velocities with the critical value obtained from a design guide. In summary, the feasibility of developing a heat exchanger tube vibration prediction method, based on a computer simulation of flow distribution, is demonstrated. Such a method would have immediate application in …

An Evaluation of Structural Integrity of IPNS-I and ZING-P' Targets
This report discusses the design, production, and evaluation of clad uranium-alloy targets that function as spallation neutron sources in the ZING-P' and IPNS-I facilities with a pulsed (10 to 30 Hz), 500-MeV proton beam. The methodology and results of theoretical nuclear-particle transport, heat transport, and stress analyses that were used in the development of a design for the targets are described. The production of a zirconium-clad uranium-alloy cylinder for ZING-P' and Zircaloy-2-clad uranium-alloy discs for IPNS-I is discussed with particular attention to the procedural details. The theoretical analyses were verified by measuring the thermal and mechanical response of the clad uranium under conditions designed to simulate the operations of the pulsed-neutron sources.

A National CW GeV Electron Microtron Laboratory
Rising interest in the nuclear physics community in a CW GeV electron accelerator reflects the growing importance of high-resolution short-range nuclear physics to future advances in the field. To meet this need, Argonne National Laboratory proposes to build a CW GeV Electron Microtron (GEM) laboratory as a national user facility. The microtron accelerator has been chosen as the technology to generate the electron beams required for the research discussed because of the advantages of superior beam quality, low capital and operating costs and capability of furnishing beams of several energies and intensities simultaneously. A complete technical description of the conceptual design for a six-sided CW microtron (hexatron) is presented. The hexatron and three experimental areas will be housed in a well-shielded complex of existing buildings that provide all utilities and services required for an advanced accelerator and an active research program at a savings of $30 to 40 million. Beam lines have been designed to accommodate the transport of polarized beams to each area. The total capital cost of the facility will be $78.6 million and the annual budget for accelerator operations will be $12.1 million. Design and construction of the facility will require four and one half years. Staged …

ICF diagnostics. Revision 1
In the past several years there have been significant advances and accomplishments in the field of Inertial Confinement Fusion (ICF) research which are directly attributable to an active experimental program supported by the development and applications of sophisticated and specialized diagnostics instruments and techniques. The continued development of high temporal-and spatial-resolution diagnostics, although with a somewhat different technical emphasis than previously, is essential for maintaining progress in ICF. With the generation of inertial fusion drivers now becoming available progress toward higher density compression of fusion fuel will be attained at the expense of temperature, and consequently emissions from the targets will be limited. At the same time since the targets are being driven to higher density they are more opaque to the low-to-moderate energy x-rays (up to a few keV) and particles (alpha particles, protons, and knock-on charged particles) that have been utilized for diagnosing target performance.

Evaluation of unthrottled combustion system options for light duty applications with future syncrude derived fuels. Alternative Fuels Utilization Program
An experimental program examining the interaction between several fuel and light duty automotive engine combinations is detailed. Combustion systems addressed covered indirect and direct injection diesel and spark ignited stratified charge. Fuels primarily covered D2, naphtha and intermediate broadcut blends. Low ignition quality diesel fuels were also evaluated. The results indicate the baseline fuel tolerance of each combustion system and enable characteristics of the systems to be compared. Performance, gaseous and particulate emissions aspects were assessed. The data obtained assists in the selection of candidate combustion systems for potential future fuels. Performance and environmental penalties as appropriate are highlighted relative to the individual candidates. Areas of further work for increased understanding are also reviewed.

The Relationships Among Organizational Communication Structures and Learning Outcomes in College Level Basic Communication Courses
Based on linear models, this study demonstrated that the psychological and social structures of the classroom, viewed as a naturalistic human system, impact learning outcomes. To operationalize learning outcomes, final grades in the course and a subject self report scale tapping perceptions of utility of material taught were used. The social and psychological structures of the classroom-as-a-human-system were operationalized through the following variables: the degree of social integration of each student, based on network analytic procedures; communication apprehension of students; dimensions of perceived credibility of instructors; dimensions of interpersonal attraction to instructors; perceived satisfaction with task demands of the course; and adjusted orientation to communication, based on communication apprehension scores and network data. Data were obtained from five sections of a multi-section communication course of a large state institution of higher learning in the southwestern region of the United States. Differences in sex were not found.

An Empirical Examination of the Relationship Between Audit Committees and the Displacement of Accounting Firms
The purpose of this research was to empirically examine the relationship between audit committees and the changing of independent accounting firms, especially those independent auditor changes in which accounting firms are displaced as auditors by accounting firms that are in the larger-sized category. This research involved the testing of two different, but closely related questions. The first research question asks, "Does the existence of an audit committee of a board of directors partially explain a company's decision to change independent accounting firms?" The second research question asks, "Does the existence of an audit committee of a board of directors partially explain a company's decision to change to a larger accounting firm rather than change to an accounting firm of equal or smaller size?" Statistical models were developed for the two research questions using criteria involved in the auditor change decisions as reported in previous research studies. Eight criterion, including the existence of an audit committee, were defined specifically and incorporated into a survey instrument. The survey instrument was circulated to the accounting firms in the Dallas-Fort Worth area. The accounting firms were asked to report certain information regarding their current and previous auditing clients. Data received from the firms were …

Multivariate Correlations of Community College Environment and Course Attrition to Retention in a Selected Community College
The problem with which this study is concerned is the methodology that is used to assess the relationship between student perceptions of the college environment and student attrition. The population of the study was 329 students from a metropolitan community college who took the Student Opinion Survey, a publication of the American College Testing Service. Data on course withdrawals and non-return in a subsequent long semester were collected for the student population. The data results were analyzed statistically using analyses of variance, Pearson product moment correlation, multiple regression analysis using step-wise procedures, and factor analysis. Data were considered statistically significant at the .05 level in relation to seven hypotheses on combinations of variables that include areas of student satisfaction with the college environment, student background data, course withdrawal, and non-return in a subsequent long semester.

Infrared-Microwave Double Resonance Probing of the Population-Depopulation of Rotational States in the NO₂ and the SO₂ Molecules
A 10.6 ym C02 laser operating a power range S P 200 watts was used to pump some select vibrational transitions in the NO2 molecule while monitoring the rotational transitions (91/9—'100/10), (232f 22 ~~"*242,23> ' (402,38 "393,37) in the (0, 0, 0) vibrational level and the (8q,8—*"^1,7) rotational transition in the (0, 1, 0) vibrational level. These rotational transitions were monitored by microwave probing to determine how the population of states in the rotational manifolds were being altered by the laser. Coincidences between some components of the V3-V2 band of N02 and the C02 infrared laser lines in the 10 um region appeared to be responsible for the strong interaction between the continuous laser beams and the molecular states.
