[Letter from Bill McCarter to Jan Schronk, May 22, 1992]
Photocopy of a letter from Bill McCarter, co-director of North Texas Institute for Educators on the Visual Arts, to Jan Schronk, Art Supervisor for Hurst-Euless-Bedford ISD. To discuss the hard work done by a number of Art Specialists in Hurst-Euless-Bedford district, and that Pam Stephens took leadership and excelled in planning the 1992 Institute. As HEB ISD goes forward to build their budget for the next two years, McCarter writes if it is possible to build additional compensation for a position similar to one Pam had assumed that year, the goals of North Texas Institute for Educators on the Visual Arts is that districts take on leadership in planning and holding their own Institutes. Enclosed with the letter are two invoices.

Fundamental studies of catalytic processing of synthetic liquids
This project revolves around understanding the fundamental processes involved in the catalytic removal of harmful oxygenated organics present in coal liquids. We are modelling the complex type of sulfided Mo catalyst proposed for these reactions with simple single crystal surfaces. These display a controlled range and number of reaction sites and can be extensively characterized by surface science techniques. We then investigate the reaction pathways for representative simple oxygenates upon these surfaces.

Effects of energetical particles on ballooning modes in high temperature tokamaks
This report describes the work done by Science Applications International Corporation to study the effects of energetic particles on the microstability of a high temperature tokamak. The effects of an energetic population on ballooning modes in a large aspect ratio, shifted circular flux surface tokamak equilibrium are investigated with the newly developed gryokinetic numerical technique. The gryokinetic equations for the background ion and electron, as well as that of the energetic population are solved directly as an initial problem. The energetic particles are modeled with a slow-down distribution in energy. It is found that the ballooning mode stability of the plasma with an energetic species of increasing concentration does not differ much from an increase in the background plasma beta, except for possible energetic particle drift resonances. This result is encouraging to the idea that energetic particles such as alphas may be used to stabilize the ballooning modes in a fusion reactor.

Orientational phase transitions in alloys. [CsPb; NaSn]
Plastic crystal behavior is observed in semiconducting CsPb and NaSn at high temperature (600 and 500 C, respectively). This behavior is associated with M{sub 4}{sup 4{minus}} or A{sub 4}M{sub 4} structural units orientationally disordering about 50 C below the melting point where translational disorder sets in. This orientational disorder is different in the two phases, exhibiting jump reorientations in CsPb and a more isotropic behavior in NaSn. In other Zintl compounds such as KPb, there is a single melting point where orientational and translational disorder sets in simultaneously; the classification of the different Zintl compounds into these two different kinds of behavior will require calorimetry or neutron diffraction below the melting point.

Hydrogen generation in SRAT with nitric acid and late washing flowsheets
Melter feed preparation processes, incorporating a final wash of the precipitate slurry feed to Defense Waste Processing Facility (DWPF) and a partial substitution of the SRAT formic acid requirement with nitric acid, should not produce peak hydrogen generation rates during Cold Chemical Runs (CCR's) and radioactive operation greater than their current, respective hydrogen design bases of 0.024 lb/hr and 1.5 lb/hr. A single SRAT bench-scale process simulation for CCR-s produced a DWPF equivalent peak hydrogen generation rate of 0.004 lb/hr. During radioactive operation, the peak hydrogen generation rate will be dependent on the extent DWPF deviates from the nominal precipitate hydrolysis and melter feed preparation process operating parameters. Two actual radioactive sludges were treated according to the new flowsheets. The peak hydrogen evolution rates were equivalent to 0.038 and 0.20 lb/hr (DWPF scale) respectively. Compared to the formic acid -- HAN hydrolysis flowsheets, these peak rates were reduced by a factor of 2.5 and 3.4 for Tank 15 and Tank 11 sludges, respectively.

Limits for the new DWPF melter off-gas jumper I. D
In order to minimize solids deposition in the off-gas line between the primary film cooler and the quencher, Savannah River Laboratory (SRL) recommended earlier that a new DWPF melter off-gas jumper be built which would increase the off-gas velocity from less than 40 ft/s under the original design to at least 55 ft/s, excluding the melter air inleakage. Two design changes proposed for the new jumper were: (1) relocation of the entry point for the melter pressure control air from the current position near the quencher to near the film cooler exit, and (2) reduction of the inside diameter of the jumper from 8.33 to 7.156 inches. The objective of this study was to confirm the, optimum inside diameter (I.D.) proposed earlier and determine the upper and lower limits for the optimum, I.D. to initiate the actual design process. Based on more conservative bases for optimization used in this study, it was determined that the design limits for the new jumper I.D. is 7.15 [le] I.D. [le] 7.25 inches.

Effect of Pb and air absorber thickness on [sup 137]Cs signal
We present the results of a measurement to understand the effects of transverse misplacement of the [sup 137]Cs source tube inside the cast Pb plates of the SDC EMC calorimeter. The PMT current from a scintillator was measured as the [sup 137]Cs source was displaced by varying thicknesses of Pb, as well as varying thicknesses of air gap. At a nominal depth of 2 mm in Pb, we find a change in scintillator output of about 25%/mm, and about 10%/mm of air gap. The data are compared to a simple calculation. By taking the sum of the scintillators on top and below a source tube, we estimate a source tube displacement of [plus minus]450[mu] will cause an error in the PMT output by 1%.

Technical bases for the salt processing cell dilution strategy for the low nitrite process
This document recommends an interim dilution strategy for the low nitrite precipitate hydrolysis process. A minimum carbon dioxide purge rate of 27 scan during feeding and for 15 minutes after feeding and a maximum precipitate slurry feed rate of 36 gpm are recommended. These recommendations provide an interim dilution strategy that will provide for the start of cold chemical runs and until additional offgas data is collected from the PHEF (Precipitate Hydrolysis Experimental Facility).

Underground radionuclide migration at the Nevada Test Site
This document reviews results from a number of studies concerning underground migration of radionuclides from nuclear test cavities at the Nevada Test Site (NTS). Discussed are all cases known to the Department of Energy's Hydrology and Radionuclide Migration Program where radionuclides have been detected outside of the immediate vicinity of nuclear test cavities that are identifiable as the-source of the nuclides, as well as cases where radionuclides might have been expected and were intentionally sought but not fixed. There are nine locations where source-identifiable radionuclide migration has been detected, one where migration was purposely induced by pumping, and three where migration might be expected but was not found. In five of the nine cases of non-induced migration, the inferred migration mechanism is prompt fracture injection during detonation. In the other four cases, the inferred migration mechanism is water movement. In only a few of the reviewed cases can the actual migration mechanism be stated with confidence, and the attempt has been made to indicate the level of confidence for each case. References are cited where more information may be obtained. As an aid to future study, this document concludes with a brief discussion of the aspects of radionuclide migration that, …

Power to detect normal mixtures: Simulation results
Twenty tests for normality were compared for the purpose of detecting mixtures of two normal components with unequal means but equal variance. The purpose of this study was to determine the power of tests specifically designed to detect mixtures, i.e., the likelihood ratio and Engelman-Hartigan tests, relative to other tests for normality. We considered the entire range of mixing proportions [pi], 0 < [pi] < 1. For mixtures that are nearly symmetric (0.35 < [pi] < 0.65) the Engelman-Hartigan test was the most powerful. When [pi] > 0.85 or [pi] < 0.15, [radical]b[sub 1] was among the best tests. For intermediate mixing proportions, the likelihood ratio test was best. For situations in which the preferred test had power 50% or more, the power of the likelihood ratio test was also above 50% and within 15 percentage points of the preferred test.

Pulsed laser kinetic studies of liquids under high pressure
A laser flash photolysis kinetic study of 2,2{prime}-bipyridine bidentate chelating ligands with one claw in the first coordination sphere of a molybdenum carbonyl complex has been completed at pressures up to 150 MPa. The reaction mechanism for thermal ring closure is found from activation volumes to change from associative interchange to dissociative interchange as substituents on the 2,2{prime}-bipyridine ligands become bulkier. In a similar study of more rigid, substituted phenanthroline bidentate ligands it was found that substituent bulkiness had little effect on the thermal ring closure mechanism. Stability constants for lithium ion complexes with crown ethers in a room temperature molten salt, fluorescence quantum yields for cresyl violet and several other dyes in solution, and the oxidation of alcohols by OsO{sub 4} have also been investigated.

A survey of problems in divertor and edge plasma theory
Theoretical physics problems related to divertor design are presented, organized by the region in which they occur. Some of the open questions in edge physics are presented from a theoretician's point of view. After a cursory sketch of the fluid models of the edge plasma and their numerical realization, the following topics are taken up: time-dependent problems, non-axisymmetric effects, anomalous transport in the scrape-off layer, edge kinetic theory, sheath effects and boundary conditions in divertors, electric field effects, atomic and molecular data issues, impurity transport in the divertor region, poloidally localized power dissipation (MARFEs and dense gas targets), helium ash removal, and neutral transport. The report ends with a summary of selected problems of particular significance and a brief bibliography of survey articles and related conference proceedings.
