User's manual for CNVUFAC, the general dynamics heat-transfer radiation view factor program

Description: CNVUFAC, the General Dynamics heat-transfer radiation veiw factor program, has been adapted for use on the LLL CDC 7600 computer system. The input and output have been modified, and a node incrementing logic was included to make the code compatible with the TRUMP thermal analyzer and related codes. The program performs the multiple integration necessary to evaluate the geometric black-body radiaton node to node view factors. Card image output that contains node number and view factor informatio… more

Raman spectroscopic studies of isotopic diatomic molecules and a technique for measuring stable isotope ratios using Raman scattering. [Cross sections]

Description: A method for measuring stable isotope ratios using Raman scattering has been developed. This method consists of simultaneously counting photons scattered out of a high-intensity laser beam by different isotopically-substituted molecules. A number of studies of isotopic diatomic molecules have been made. The Q-branches of the Raman spectra of the isotopic molecules /sup 14/N/sup 15/N and /sup 16/O/sup 18/O were observed at natural abundance in nitrogen and oxygen samples. Comparison of the ratio… more

Slicing of silicon into sheet material. Silicon sheet growth development for the large area silicon sheet task of the low cost silicon solar array project. Second quarterly report, March 22, 1976--June 20, 1976

Description: Slicing tests of silicon to show the dependence of cutting rate on operating conditions are complete. Cutting rate is linear with cutting force per blade and bladehead speed, and inversely proportional to kerf width (loss) and kerf length. The dimensionless parameter of cutting efficiency is a good measure of the performance of a multiblade slicing system. Low contact pressure between the blades and the silicon workpiece result in increased wafer accuracy and cutting efficiency. Blade wear seem… more

Analysis of the custom design/fabrication/testing requirements for a large-hole drilling machine for use in an underground radioactive waste repository

Description: An analysis of the fabrication and field test requirements for a drilling machine that would be applicable to the drilling of large diameter holes for the emplacement of radioactive waste canisters in an underground repository is presented. On the basis of a previous study in 1975 by RE/SPEC Inc. for the Oak Ridge National Laboratory, it was concluded that none of the commercially available machines were ideally suited for the desired drilling application, and that it was doubtful whether a mac… more

Development of optimum conditions for drying ion exchange resin in a fluidized bed dryer

Description: Drying of Amberlite IRC-72 ion exchange resin in a fluidized bed dryer was investigated. Resin water content was measured as a function of drying time for various drying temperatures, bed loadings, and air flow rates. An incomplete equation for the induction period and complete model for constant rate drying were developed. Further development of an induction period model requires installation of an accurate air flow measurement device. A drying temperature of 200/sup 0/F results in the shortes… more

Evaluation of existing polymer characterization techniques and capabilities of the General Chemistry and Organic Materials Divisions in the Chemistry and Materials Science Department

Description: This report begins with definitions of characterization and testing, then continues with the evaluation of thirteen specific techniques including various spectroscopy, thermal, solutional properties, wet chemistry, chromatography and miscellaneous procedures. Comments and recommendations on the need for an analytical services focal point in GCD, a polymer characterization expert in OMD and the use of contractor facilities as a source of data gathering are made. It is concluded that substantial … more

Floating substrate process. Second quarterly progress report, March 29, 1976--June 20, 1976

Description: This research program began January 6, 1976. Its objective is to demonstrate the feasibility of the floating substrate sheet growth process for the growth of silicon sheet. This process is an approach to the formation of single-crystal silicon by direct epitaxial conversion from a gaseous silane. Incoming feedstock gas impinges upon a silicon substrate which is floating upon a thin pool of liquid tin. Single-crystal silicon grows to the desired thickness by means of vapor phase epitaxy. Nucleat… more

Calorimeters for diagnosis of laser-fusion experiments

Description: A variety of calorimeters have been developed for measuring ions, x-rays, and scattered radiation emanating from laser-pulse-imploded fusion targets. The ion and x-ray calorimeters use metal or glass absorbers to reflect or transmit most of the scattered laser radiation; the versions using metal absorbers also incorporate a differential construction to compensate for the fraction of the scattered laser radiation that is absorbed. The scattered-radiation calorimeters use colored glass to absorb … more

Treatment of waste lubricating oil using BERC/ERDA solvent

Description: From data generated in the laboratory and pilot plant studies a quality rerefined oil can be produced via BERC/ERDA solvent extraction and clay treatment. Some of the important processing variables that determine the quality of the finished product are temperature of solvent extraction, type of clay used, temperature and time of clay treatment, and the atmosphere under which the oil is treated with clay. Yields of 75 percent based on water-distillate-free oil can be expected at the conditions u… more

Gamma-ray isotopic ratio measurements for the plutonium inventory verification program

Description: The Plutonium Inventory Verification Program at Mound Laboratory provides a nondestructive means of assaying bulk plutonium-bearing material. The assay is performed by combining the calorimetrically determined heat output of the sample and the relative abundances of the heat-producing isotopes. This report describes the method used for the nondestructive determination of plutonium-238, -240, -241 and americium-241 relative to plutonium-239 using gamma-ray spectroscopy for 93 percent plutonium-2… more
