[Letter from Cassandra Broadus to Sylvia Crutsinger, February 13, 1991]
Photocopy of a letter from Cassandra Broadus, North Texas Institute for Educators on the Visual Arts, to Sylvia Crutsinger, teacher at Pilot Point Elementary. Thanking Crutsinger to allowing Broadus to visit her classroom, she enjoyed working with her students and seeing their participation in the art session. Broadus writes that she is interested in continuing the writing and art correlation and thinking of ways to make abstract concepts work with first grade children, when she visits Pilot Point again she'll want to discuss ideas with Crutsinger.

[Letter from Cassandra Broadus to Jeannine Sellmeyer, February 13, 1991]
Photocopy of a letter from Cassandra Broadus to Jeannine Sellmeyer, Director of Education at the Denton Co. Historical Museum, in regards to a previous discuss they had during a meeting. Broadus mentions that a lot of art related activities could be made with the pieces from the museum's collection, and enclosed information Sellmeyer could use as she begins to think about developing teacher packets.

Site development plan for Oak Ridge National Laboratory, Martin Marietta Energy Systems
The Oak Ridge National Laboratory (ORNL) is responsible for developing new and environmentally acceptable energy technologies that will offer the nation safe options for energy supply and efficient systems for energy use. Martin Marietta Energy Systems, Inc., (Energy Systems) operates ORNL under a management and operating contract. The purpose of the audit was to review and evaluate the effectiveness of site development planning activities at ORNL. A site development plan is a long-range master plan for the acquisition, development, utilization, and disposal of land and physical facilities at a specific US Department of Energy (DOE) facility. ORNL did not have a current site development plan and had not submitted updates to the old plan. This condition existed because the DOE Field Office, Oak Ridge (OR), and ORNL management had not implemented their responsibilities set forth in applicable DOE orders for site development planning. As a result, DOE had no assurance that ORNL real property holdings would be planned and developed economically and efficiently.

Gaussian dispersion and dosimetric modeling sensitivity to area-specific 1982--86 meteorological data collected at the Savannah River Site
Radiological dose to the offsite maximum individual or the 50-mile population is often estimated assuming that operational atmospheric releases originate from the geographical center of the Savannah River Site. Historically, meteorological data collected from instrumentation on the H-Area tower have been utilized to estimate atmospheric dispersion from centrally located releases.'' This paper examines the effect on dose predictions using meteorological data from seven onsite towers located at A, C, D, F, H, K, and P areas to describe meteorological conditions at the central release location. Maximum individual dose estimates using both annual and short-term average air concentrations are well within 20% of the mean prediction. Population dose estimates are also within 20% of the mean prediction. Population dose estimates are also within 20% of the mean except for two-hour doses using H-Area meteorological data, which is less than the average estimate by about 30%.

The production of sulfate particles through the radiolytic oxidation of sulfur dioxide
The production of hydroxyl radicals by the radiolytic decomposition of water vapor following alpha decay of {sup 222}Rn can be used to produce an ultrafine sulfuric acid aerosol in the presence of SO{sub 2}. In the past, the production of this aerosol appeared to have a limiting threshold in as much as sufficient conversion of SO{sub 2} to SO{sub 4} must be attained to achieve the concentration required for nucleation. This appeared to occur when the bulk average acidity reached an adequately high value. The threshold curve for the onset of the sulfuric acid aerosol formation is a function of the H{sub 2}O, SO{sub 2} and Rn concentrations. The hydroxyl radical formation is dependent on the H{sub 2}O and Rn concentrations. The mass conversion rate of SO{sub 2} to H{sub 2}SO{sub 4} has been studied by measuring the airborne H{sub 2}SO{sub 4} concentration by ion chromatography after it has been collected on a filter and leached into solution. 39 refs., 9 figs.

Molten salt processing of mixed wastes with offgas condensation
We are developing an advanced process for treatment of mixed wastes in molten salt media at temperatures of 700--1000{degrees}C. Waste destruction has been demonstrated in a single stage oxidation process, with destruction efficiencies above 99.9999% for many waste categories. The molten salt provides a heat transfer medium, prevents thermal surges, and functions as an in situ scrubber to transform the acid-gas forming components of the waste into neutral salts and immobilizes potentially fugitive materials by a combination of particle wetting, encapsulation and chemical dissolution and solvation. Because the offgas is collected and assayed before release, and wastes containing toxic and radioactive materials are treated while immobilized in a condensed phase, the process avoids the problems sometimes associated with incineration processes. We are studying a potentially improved modification of this process, which treats oxidizable wastes in two stages: pyrolysis followed by catalyzed molten salt oxidation of the pyrolysis gases at ca. 700{degrees}C. 15 refs., 5 figs., 1 tab.

Steam gasification of carbon: Catalyst properties
This research uses several techniques to measure the concentration of catalyst sites and determine their stoichiometry for the catalyzed gasification of carbon. Both alkali and alkaline earth oxides are effective catalysts for accelerating the gasification rate of coal chars, but only a fraction of the catalyst appears to be in a form that is effective for gasification, and the composition of that catalyst is not established. Transient techniques with {sup 13}C labeling, are being used to study the surface processes, to measure the concentration of active sites, and to determine the specific reaction rates. We have used secondary ion mass spectrometry (SIMS) for both high surface area samples of carbon/alkali carbonate mixtures and for model carbon surfaces with deposited alkali atoms. SIMS provides a direct measure of surface composition. The combination of these results can provide knowledge of catalyst dispersion and composition, and thus indicate the way to optimally utilize carbon gasification catalysts.
