Analysis of the heat and mass transfer processes of a UO/sub 2/ bubble in sodium for the Fuel Aerosol Simulant Test (FAST). [LMFBR]
The anticipated behavior of uranium oxide vapor bubbles produced by the capacitor discharge vaporization (CDV) method in the Fuel Aerosol Simulant Test (FAST) Facility is discussed on the basis of relatively simple physical models. Results of calculations for the rate of bubble rise and for heat and mass transfer rates are presented. Parametric studies indicate that future analysis efforts should emphasize the diffusion condensation process and the loss of heat from the bubble by radiation. Transfer of heat in the surrounding sodium is rapid enough that simplified models should be adequate. No important effects were noted in connection with bubble depth, initial quantity of UO/sub 2/, or initial superheat.

Analysis of the Z dependence of laser generated suprathermal electron temperature
Recent experiments with high Z disks on the Argus facility have exteanded our knowledge of the temperature (inferred from the slope of the hard x-ray spectrum) of laser generated suprathermal electrons, from the previous regime of 1 less than or equal to Z less than or equal to 30 to the Z approx. = 80 regime. The systematic rise of temperature with Z is theoretically analyzed. We believe that material albedoes (electron reflectivity) which increase with Z can account for this behavior, since electrons can make multiple passes through the region of resonant electric fields and are thus reheated. We treat this effect quantitatively and obtain reasonable agreement with experiment. The effects of magnetic fields and filamentation are also examined.

Technique for full surface examination of small spheres in the scanning electron microscope
In response to the increasing severity of target surface finish requirements for laser fusion experiments, it has become necessary to examine spherical targets in the Scanning Electron Microscope, prior to laser irradiation, on an orderly nondestructive basis. We have developed a new sample manipulation technique which rolls a thin wall sphere through 4..pi.. steradians, minimizes damage and allows easy recovery. The sphere is placed between two parallel plane surfaces formed in conductively coated silicone rubber on the ends of capillaries. Mechanical slides cause the capillaries to translate laterally and roll the ball bringing the entire surface of the sphere into a position for examination. Resolutions comparable with traditional mounting techniques are attained. A side looking, Si(Li) detector increases the utility of the system by allowing simultaneous energy dispersive x-ray microanalysis. The entire detector assembly slips between the secondary electron detector and the sphere rolling capillaries to collect x-rays from the target.

Method for determining the work hardening function to describe plasticity of metals
A method for obtaining a constitutive relation that relates the flow stress to the equivalent plastic strain is developed. The method uses simple tension test data to suggest a functional form. This form is then used as a constitutive model in a computer program that simulates the tension test. The calculated results are compared with the experimental results and the functional form is refined until agreement is obtained between calculations and experiments. The importance of knowing the relationship between the flow stress and the plastic strain is discussed. A work hardening function is calibrated for 6061 T6 aluminum.

Automation of the Jarrell--Ash model 70-314 emission spectrometer
Automation of the Jarrell-Ash 3.4-Meter Ebert direct-reading emission spectrometer with digital scaler readout is described. The readout is interfaced to a Data General NOVA 840 minicomputer. The automation code consists of BASIC language programs for interactive routines, data processing, and report generation. Call statements within the BASIC programs invoke assembly language routines for real-time data acquisition and control. In addition, the automation objectives as well as the spectrometer-computer system functions, coding, and operating instructions are presented.
