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 possible that the effect may be of some concern.

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 from thermal expansions of the constituents. The expansion of the mixture was computed by weighting and expansions of the constituents according to (1) weight percent of the constituents, (2) volume percent of the constituents and (3) according to a value developed for mixtures by P. S. Turner. It was found that expansions computed according to volume percent and by Turner's method agreed with measured values with +- 5 percent. The values calculated by weight percent were from 5 to 11 percent higher than the observed values. The thermal expansions of these cermets are compared with the expansions of a group of metals and alloys.

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 second constant temperature experiment (1806/sup 0/K) the vapor composition in equilibrium with nearly stoichiometric titanium monoxide was measured mass spectrometrically. The mass spectrometer results were used to apportion the total titanium collected in the first experiment to Ti(g) and TiO(g). In the third experiment the temperature dependence of the ions Ti/sup +/(48) and TiO(64) was measured spectrometrically. The results obtained in this work are compared with published thermodynamic properties of the titanium oxygen system, and indicate the standard free energy of formation of titanium monoxide obtained from the earliest calorimetric measurements yielded a result not negative enough and also oxygen pressures obtained by emf measurements for stoichiometric titanium monoxide at 1806/sup 0/K are high by a factor of 42.6. The present results are in good agreement with the thermodynamic properties reported in recently issued pages of the JANAF Thermochemical Tables.

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 other nucleating faults under the assumption that equilibrium among the clusters prevails and that the vacancies resulting from neutron damage are primarily in clusters rather than randomly distributed

Innovative Clean Coal Technology (ICCT): 180 MW demonstration of advanced tangentially-fired combustion techniques for the reduction of nitrogen oxide (NO{sub x}) emissions from coal-fired boilers. Topical report, LNCFS Levels 1 and 3 test results

Description: This report presents results from the third phase of an Innovative Clean Coal Technology (ICC-1) project demonstrating advanced tangentially-fired combustion techniques for the reduction of nitrogen oxide (NO{sub x}) emissions from a coal-fired boiler. The purpose of this project was to study the NO{sub x} emissions characteristics of ABB Combustion Engineering`s (ABB CE) Low NO{sub x} Concentric Firing System (LNCFS) Levels I, II, and III. These technologies were installed and tested in a stepwise fashion at Gulf Power Company`s Plant Lansing Smith Unit 2. The objective of this report is to provide the results from Phase III. During that phase, Levels I and III of the ABB C-E Services Low NO{sub x} Concentric Firing System were tested. The LNCFS Level III technology includes separated overfire air, close coupled overfire air, clustered coal nozzles, flame attachment coal nozzle tips, and concentric firing. The LNCFS Level I was simulated by closing the separated overfire air nozzles of the LNCFS Level III system. Based upon long-term data, LNCFS Level HI reduced NO{sub x} emissions by 45 percent at full load. LOI levels with LNCFS Level III increased slightly, however, tests showed that LOI levels with LNCFS Level III were highly dependent upon coal fineness. After correcting for leakage air through the separated overfire air system, the simulated LNCFS Level I reduced NO{sub x} emissions by 37 percent. There was no increase in LOI with LNCFS Level I.

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 these three cases are 1.09, 1.18 and 1.36 g/cc respectively. Since no collector was added to the suspension, all the solids are expected to report to the underflow. For all these studies the Q* value was maintained at the same level (Q* = 2.28). Reconstructed images from the CT scanner were analyzed using the graphics software developed at the University of Utah. Assuming the air core to be cylindrical in shape and using the previously generated calibration curve, the average density of the swirl layer and its average thickness were estimated for each slice. These results are presented graphically in the accompanying figures along the axis of the ASH unit from bottom to top.

End-use taxes: Current EIA practices

Description: There are inconsistencies in the EIA published end-use price data with respect to Federal, state, and local government sales and excise taxes; some publications include end-use taxes and others do not. The reason for including these taxes in end-use energy prices is to provide consistent and accurate information on the total cost of energy purchased by the final consumer. Preliminary estimates are made of the effect on prices (bias) reported in SEPER (State Energy Price and Expenditure Report) resulting from the inconsistent treatment of taxes. EIA has undertaken several actions to enhance the reporting of end-use energy prices.

Polyethylene encapsulation of simulated blowdown waste for SEG treatability study. Letter report on Phase I screening: Waste treatment and specimen preparation

Description: The Environmental and Waste Technology Center is a participating subcontractor in the Scientific Ecology Group (SEG) Treatability Study for Westinghouse Savannah River Co.`s Blowdown Waste. This waste will be generated at the Consolidated Incinerator Facility (CIF) and will consist of the neutralized aqueous scrubber solution from the incinerator. Since the facility is designed to burn low-level radioactive, hazardous, and mixed wastes, the blowdown waste will likely be a mixed waste. Polyethylene encapsulation is an improved treatment method that has been developed at BNL over the last 10 years. Polyethylene is an inert, thermoplastic polymer with a melt temperature of 120 C. The BNL process is a modification of standard plastics extrusion technology that has been utilized successfully by the plastics industry for over 50 years. Polyethylene binder and dry waste material are fed through separate calibrated feeders to the extruder, where the materials are thoroughly mixed, heated to a molten condition, and then extruded into a suitable mold. A monolithic solid waste form results on cooling. The objective of the Phase 1 screening effort was to prepare test specimens of CIF surrogate waste encapsulated in polyethylene for leach testing using EPA`s Toxicity Characteristic Leaching Procedure (TCLP). BNL received aqueous CIF surrogate from SEG, pretreated the stimulant for processing, and fabricated TCLP test specimens for analysis at an independent laboratory. Laboratory and processing procedures are described in this letter report.
