Absorber Burn-Up Experiment. Final Report

Description: Experimental results are presented of pile oscillator measurements of cross sections of irradiated samples of seventeen elements. Mass spectrometer analysis of some samples was performed. Quantitative theory-experiment correlation yielded thermal absorption cross section information and also established the reliability of control rod lifetime calculations for each element investigated. Application of the results to calculation of the nuclear lifetime of reactor control rods is discussed. (auth)

The Adsorption and Surface Reactions of Hydrocarbons on Clean Iridium

Description: The adsorption of ethane, ethylene, and acetylene on clean iridium in a field emission microscope was found to cause characteristic changes in the work function of the iridium surface. Further changes, which were time and temperature dependent, resulted when such surfaces were heated. Flash filament experiments showed that the changes in work function upon henting are due to desorption reactions and that the desorbed product consists principally of hydrogen. By assuming a linear relationship be… more

Chemical Processing of Coated Particle Fuels

Description: BS>Laboratory studies on the processing of graphite-base fuel elements containing pyrolytic carbon- or Al/sub 2/O/sub 3/-coated particles are reviewed. Potential processes for recovering U and Th from irradiated elements include grinding followed by acid leaching, and, burning and subsequent dissolution of the oxide ash. Disintegration in 90% HNO/sub 3/ was briefly evaluated as a method for determining the integrity of coated particles dispersed in graphite matrices. (auth)

Cobalt (II) Halides as Electrolytes in Acentonitrile

Description: "The electrical conductance of CoCl2 and CoBr2 from 10−4 to 10−1 mol/l over the temperature range 0–35°C is reported. The effects of water as trace impurity, and the halide common ion effect on conductance are examined. The properties of these solutes are also examined using spectrophotometry and transport numbers. Crystalline “solvated” compounds, of empirical formulae [CoX2(CH3CN)3]x can be separated from the saturated solutions. The magnetic susceptibilities of the crystalline substrates are… more

Critical Heat Flux and Flow Pattern Characteristics of High Pressure Boiling Water in Forced Convection

Description: High-speed motion pictures of boiling water flow patterns in conditions of forced flow at 1000 psia pressure in a vertical heated rectangular channel were taken at mass velocities from 50 to 400 lbs/sec-ft/sup 2/, fluid states from 170 Btu/lb buik enthalpy of subcooling to 0.68 bulk steam quality, and heat tluxes up to and including the critical heat flux level. An objective of the work was to make the results available for continued experimental and theoretical investigation of the critical he… more

Crystallographic D-Space Computer Program

Description: D-Space is a computer program which generates indices (hld), tests for space-group extinctions, and calculates d,'' 1/d/sup 2/, sin theta , sin/sup 2/ theta , sin theta / lambda , sin/sub 2/ theta / lambda /sup 2/, theta , and 2 theta for any crystal system and space group, requiring only the unit cell constants as data input. Optional calculations are the single-crystal angle settings, phi and chi, and various Lorentz and Lorentz-polarization corrections. (auth)

Effects of Fast-Neutron Irradiation and High Temperature on Beryllium Oxide

Description: Specimens of 0.428 to 1.18 in. dia. BeO were irradiated at 1.4 x 10/sup 20/ to 2.8 x 10/sup 21/ fast neutrons/cm/ (>1 Mev), with irradiation times of 2.03 x 105 to 5.60 x 106 sec, at 110 to 1025 C, and gamma heat generation rates of 18 to 25 w/g. The greatest damage appeared in bodies irradiated for high neutron doses at low temperatures. Greater doses could be tolerated at higher temperatures. Specimens irradiated at 110 deg C powdered at an accumulated dose of 1.5 x 10/sup 21/ 1.1 x 10/sup 21… more

Electric Propulsion Applications for SNAP Systems

Description: The application of SNAP systems to electric propulsion was investigated. A review is given of the basic analysis involved in establishing optimum power levels and payload capabilities for electric spacecraft, and several typical missions are analyzed to determine the usefulness of the SNAP systems which are under development or systems which are based on the current SNAP technology. In general, it is found that SNAP power units in the range of 60 to 180 kw offer significant mission capability w… more

Emission Characteristics of Tantalum, Tungsten, Rhenium, and Iridium in Plasma Diodes

Description: Experimental determinations of the ionic and electronic emission characteristics of tantalum, tungsten, rhenium, and iridium cathodes in vapor thermionic converters are compared. It is shown that tantalum provides superior thermal ionization qualities at high pressure compared with tungsten, rhenium, and iridium. High electronic current densities may be obtained from cesium on rhenium and cesium on iridium at much lower cesium vapor pressures than for tantalum or tungsten. (auth)

HALL PROBE REGULATION OF EXPERIMENTAL POWER SUPPLIES

Description: The Hall mode of operation utilizes a signal derived from the magnetic field of an experimental magnet to provide the power supply regulator with the information necessary for it to regulate the magnet current. Regulation of the field to 0.1% is possible with the Hall probes and regulators used at the Cosmotron. The Hall Effect is a phenomenon whereby the voltage developed across a semiconductor or metal is a function of the current through the material and the magnetic field intensity perpendi… more
