Elastic Scattering of 31-Mev He$sup 3$ Ions From Several Elements

Description: The absolute differential cross sections for elastic scattering of 31- Mev He/sup 3/ ions on Be, Al, Cu, Sn/sup (nat)/, Sn/sup 120/ and Bi were measured in the angular range of approximately 10 to 120 deg in the center-of-mass system. Thin selfsupporting foil targets were chosen to span the parameter A/sup 1/3/, where A is the target mass number. The first excited states of the isotopes of these elements had sufficient energy separation from the ground state to enable elastic scattering to be r… more

Deuterium-Hydrogen Exchange in Boehmite Corrosion Product Formed on Pure Aluminum in Boiling Water

Description: Proton-deuteron exchange is rapid in boehmite corrosion product formed on pure aluminum in boiling water. In addition, deuterated boehmite films undergo rapid exchange with the humidity of the atmosphere. This explains the previously reported anomaly in the H-D exchange rate for the growing corrosion product on 1100 aluminum. (auh)

Development of Clad Ceramic Fuel Plates by Spray-Coating Techniques. Final Report, Phase I

Description: Activities in a program to develop techniques of plasma spraying clad plate-type UO/sub 2/ fuel elements are reported. The investigation was also directed toward determining the limitations of the process as applied to fuel element fabrication. UO/sub 2/ powder coatings having densities of 90% theoretical were produced. At conditions required for spraying plates, densities of 86% appear to be practical. The rate and efficiency of UO/sub 2/ coating deposition were also determined for various spr… more

Development of Clad Ceramic Fuel Plates by Spray-Coating Techniques. Quarterly Technical Progress Report, January-March 1961

Description: The development of plasma-jet spray-coating techniques for producing clad ceramic fuel plates is discussed. Conditions for spraying fused UO/sub 2/ powder were established by depositing cones on stationary substrates. It was found that the arc-gas flow range within which deposition occurs is very narrow. Coatings were made from --200 +325, --270 + 325, and de-slimed -325 mesh fused UO/ sub 2/ powders. To provide data regarding the economics of the process, deposition rates and efficiencies were… more
