Catalysts and process development for synthesis gas conversion to isobutylene. Quarterly report, July 1, 1991--September 30, 1991
The objectives of this project are to develop a new catalyst, the kinetics for this catalyst, simulate the performance of fixed bed trickle flow reactors, slurry flow reactors, and fixed bed gas phase reactors for conversion of a hydrogen-lean synthesis gas to isobutylene. The goals for this year were to recruit and organize the project team, complete the literature and patent searches, complete the management plan and other reporting requirements, complete the revision and upgrading of existing bench scale units for the project, and synthesize, characterize and evaluate the catalytic activity of zirconia prepared (1) by co-precipitation of zirconyl nitrate with ammonium hydroxide and (2) by preparing a hydrous zirconium oxide using the modified sol gel method developed at the Sandia National Laboratories followed by calcination. The same preparation procedure would be used to prepare supports for impregnation with thorium nitrate, a potassium salt and a sodium salt. The synthesis of new crystalline zirconates were to be attempted with the objective of producing new compositions of matter which might have higher activities and selectivities than zirconia. Substantial progress on reactor and kinetic models for slurry and trickle bed reactors was to be achieved. Accomplishments for the year are described.

Modelling chronic atmospheric releases at the SRS: Evaluation and verification of XOQDOQ. [Atmospheric dispersion code used to estimate concentrations resulting from chronic releases of radioactivity]
XOQDOQ is the atmospheric dispersion code used by the Savannah River Laboratory to estimate offsite concentrations resulting from chronic releases of radioactivity. This report documents evaluation and verification studies performed on XOQDOQ. The studies were designed to establish compliance with Site quality assurance requirements for high-impact software. Comparisons of XOQDOQ results with that of a series of spreadsheets indicate that the code is performing as intended by the designers. Relative concentration and deposition values, {chi}/Qs and D/Qs, calculated by the two methods differed by no more than 0.5% in any of the test cases. Estimates of ground-level air concentrations at the Site boundary calculated with XOQDOQ were compared with tritium concentrations measured at those locations. XOQDOQ generally overestimates tritium concentrations by a factor of 1 to 3. Other radionuclides released in recent years by the SRS have not been present in sufficient concentrations to permit evaluation efforts. However, previous studies of Kr-85, I-129, and Pu-238 have shown XOQDOQ predictions of offsite air concentrations to be adequate. Based on this review, the performance of XOQDOQ is acceptable for continued use at the SRS. Efforts to improve the code should also be continued. Sensitivity studies to such parameters as particle size distribution, …

Ringlight for use in high radiation
The present invention relates generally to ringlight for providing illumination about a central viewing area and more particularly to an improved ringlight design suitable for use in automatic gaging applications conducted in hostile radioactive environments. It is a further object of the present invention to provide a ringlight which is relatively simple in construction and with few parts, and which is thus very reliable in operation. The above and other objects are achieved in the present invention by a ringlight providing an annular array of light-emitting elements centered about a viewing passage, wherein the improvement comprises: a first annular body, a second annular body mounted concentrically within the first annular body so as to form an annular void and light-emitting aperture therebetween, and a plurality of optical fibers extending into the void with end portions thereof secured therein so as to form an annular array of optical fiber end surfaces at said light-emitting aperture, the first and second bodies cooperating to angle the end portions of the plurality of optical fibers toward a central axis of the viewing passage.

Public opinion and nuclear power decision-making
This document discusses public opinion regarding nuclear power which is particularly difficult to tie down because of five important paradoxes that characterize it: it can be based on sound reason, but also on intense emotion; it is both national and local in perspective; at varying times it has seen nuclear power as both clean'' and dirty''; it believes nuclear power is both economic, and uneconomic; and nuclear power is perceived as having a fairly safe record, but being potentially unsafe. Equally as complex as the process by which public opinion is formed is the process by which it is converted into public policy. The American political system has numerous checks and balances designed to moderate the power of public opinion. A complex series of legislative, judicial, and executive branch hurdles must be cleared before any idea, however popular, can become day-to-day operating reality in government. As a result, major changes in policy or programs are difficult, and we may expect that nuclear power will be no different; radical change in one direction or the other is unlikely. Nevertheless, carefully focused programs could achieve modest progress, and carefully designed public opinion surveys could support such programs.

[Letter from Cassandra Broadus to Melanie Wright, March 6, 1991]
Photocopy of a letter from Cassandra Broadus, North Texas Institute for Educators on the Visual Arts, to Melanie Wright, Dallas Museum of Art. Broadus requests the use of two or three permanent pieces from the DMA to use in "Art-O-Gram" and "Class Acts" an art education newspaper series in the Fort Worth Star Telegram. The articles are designed for children to give them something more than just an art project but to talk about and view work critically and develop better communication skills.
