[Letter from Bill McCarter to Jan Schronk, May 22, 1992]

Description: 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 posi… more

Fundamental studies of catalytic processing of synthetic liquids

Description: 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 th… more

Effects of energetical particles on ballooning modes in high temperature tokamaks

Description: 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 … more

Orientational phase transitions in alloys. [CsPb; NaSn]

Description: 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 … more

Hydrogen generation in SRAT with nitric acid and late washing flowsheets

Description: 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 equivalen… more

Limits for the new DWPF melter off-gas jumper I. D

Description: 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 pos… more

Effect of Pb and air absorber thickness on [sup 137]Cs signal

Description: 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 calcu… more

Technical bases for the salt processing cell dilution strategy for the low nitrite process

Description: 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

Description: 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 intention… more

Power to detect normal mixtures: Simulation results

Description: 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 te… more

Pulsed laser kinetic studies of liquids under high pressure

Description: 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 bi… more

A survey of problems in divertor and edge plasma theory

Description: 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 … more

Ruthenium volatility from the vitrification of melter feeds prepared using the Nitric Acid Flowsheet

Description: The present DWPF flowsheet calls for the chemical treatment of waste sludge with 90 wt% formic acid prior to the addition of the Precipitate Hydrolysis Aqueous (PHA) product. An alternative processing methodology, denoted the ``Nitric Acid Flowsheet``, has been proposed. In the application of this flowsheet, nitric acid would be used to neutralize sludge base components (hydroxides and carbonates) prior to the addition of late wash PHA. The late wash PHA will contain sufficient quantities of fo… more

Measurement of local void fraction in a ribbed annulus

Description: The computer code FLOWTRAN-TF is used to analyze hypothetical hydraulic accidents for the nuclear reactor at the Savannah River Site. During a hypothetical Large Break Loss-of-Coolant Accident (LOCA), reactor assemblies would contain a two-phase mixture of air and water which flows downward. Reactor assemblies consist of nested, ribbed annuli. Longitudinal ribs divide each annulus into four subchannels. For accident conditions, air and water can flow past ribs from one subchannel to another. Fo… more
