Division of Reactor Development Programs Monthly Report- July 1959

Description: Basic Studies. Sinterability studies on the isomorphous system UO2-PuO2 have continued. One-half inch diameter X 3/8'' long compacts containing physical mixtures of the two components have been heated in hydrogen. Sintered density as a function of time and temperature has been determined for times of one and eight hours up to 1600 C. In general, there seems to be minima on isothermal plots of density versus composition in the intermediate range 20-40 w/o PuO2. At concentrations greater than 40 … more

Sheet Metal Can Furnace

Description: A need for a small vertical cylinder-type furnace arises frequently in the Chemistry Department at the Lawrence Radiation Laboratory (LRL). Adequate heat is the major requirement; close control or calibration is not usually necessary. A heating unit of this type can either be used for quickly concentrating solutions in centrifuge cones or, by the addition of a refractory pedestal--can be made into a crucible furnace for size 0 and 00 crucibles. Because much of the chemistry done at LRL is with … more

Fabricating Liquid-Hydrogen Targets From Mylar

Description: The increasing popularity of liquid-hydrogen targets in physics research has emphasized the need for containers with maximum beam transparency (i.e., thin walls and low Z) and suitable strength at cryogenic temperatures. Fabrication of a Mylar container satisfying these requirements is described here.

Close-Capture Adsorption System For Remote Radioisotope Chemistry

Description: Molecular sieves are synthetic zeolites which, when dehydrated, contain a network of empty pores and cavities that constitute almost 50% of the total volume of the crystals. They have the unique property of adsorbing within these cavities only those molecules that are small enough to pass through the pores of the crystals, Molecular sieves have a very strong affinity for water and other polar molecules. It is this selective property plus their stability and reasonable cost that make them of int… more

Warping Instability in Long Rods

Description: Abstract. If a pile rod gets bowed within its cooling tube it becomes warmer on the side which approaches the tube wall, and thermal expansion tends to warp it in the same direction as the original displacement. This was discussed roughly in N-601, and it was there concluded that the mechanism was not important for an isolated short slug. In connection with current development of continuous jacket (cartridge) assemblies, it seems desirable to look at this question again. In this case it is poss… more

The Thermal Expansion of Five Titanium Carbide Cermets from 68 to 1800F

Description: This technical report presents measurements of the thermal expansion of five titanium carbide type cermets from 68 to 1800F. These cermets are designated by Kennametal, Inc., as K 138A, K 150A, K 152B and K 162B. They contain from 64 to 80 weight percent titanium carbide, 10 to 30 weight percent metal binder and 6 to 10 weight percent other carbides. The metal binders are cobalt, nickel, and nickel and molybdenum. An attempt was made to calculate the thermal expansion of each type cermet fr… more

Monitoring Thermal and Resonance Neutron Flux

Description: The monitoring of thermal and resonance neutron flux in a thermal reactor having high flux over periods of time from 1 to 12 months using think Co foils is considered. Special attention is paid to the many correction factors to be applied to the activation data; neutron temperature, effective cadmium cutoff energy, burnout of Co59 and Co60, and decay of Co60. Results on a homogeneity test of 10 mil, 0.08% Co-A1 alloy foils is given.

Maximum acceptable temperatures of wastes and containers during retrievable geologic storage

Description: Estimates of maximum acceptable temperatures of waste and containers during retrievable geologic storage were needed for use in evaluating and comparing conceptual designs for repositories for wastes from reprocessing and for spent fuel in several different rock types. Estimates of these temperatures and discussions of the bases for the estimates are presented.

Improved beam current densities at high voltages

Description: The performance of ion extractors is analyzed with crude approximations that show improved performance to be possible with the certain modifications. However, additional studies are required to evaluate the beam optics in the presence of the deformed grids.

High temperature thermodynamics and vaporization of stoichiometric titanium monoxide

Description: Three vaporization experiments were performed on samples of nearly stoichiometric titanium monoxide. Two experiments were constant temperature experiments (1806/sup 0/K) designed to measure the equilibrium vapor pressures of Ti(g) and TiO(g). In one experiment titanium monoxide was vaporized from a tungsten Knudsen effusion cell; the vapor was collected on a water cooled quartz cap surrounding the cell; and the total amount of titanium deposited on the cap was analyzed colorimetrically. In the … more

July 2004 Working Group Meeting on Heavy Vehicle Aerodynamic Drag: Presentation, Summary of Comments, and Conclusions

Description: A Working Group Meeting on Heavy Vehicle Aerodynamic Drag was held in Portland, Oregon on July 1, 2004. The purpose of the meeting was to provide a summary of achievements, discuss pressing issues, present a general overview of future plans, and to provide a forum for dialogue with the Department of Energy (DOE) and industry representatives. The meeting was held in Portland, because the DOE Aero Team participated in an exclusive session on Heavy Truck Vehicle Aerodynamic Drag at the 34th AIAA F… more

Some Kinetic Considerations of Defect Clustering

Description: Kinetic approaches to the description of point defect clustering phenonema are reviewed. High divacancy mobility is shown to complicate both analytic and computer solutions except in the special cases in which the number of vacancy sinks is pre-established by some special characteristic of the metal under investigation. Interstitial clustering is complicated by the presence of vacancies. An approximate solution has been found for interstitial clustering kinetics in the presence of impurities or… more

Characterization of multiphase fluid flow during air-sparged hydrocyclone flotation by x-ray CT. Eighth quarterly report, 14 May 1992--13 August 1992

Description: The effect of A* (the dimensionless ratio of overflow opening area to underflow opening area) on the fluid flow behavior of the 2 inch ASH-2C unit was studied for different percentage of solids in the suspension. Limestone, a hydrophilic solid was chosen for study. The particle size of the solids was taken as {minus}100 {plus}200 mesh. Three different concentrations of solids in the suspension were considered, 5, 10 and 20% by weight. The corresponding pulp densities of the feed suspension for … more
