Beryllium Metallurgiy. Results of chemical analysis of O/sub 2/ in beryllium are reported. Diffusion couples were prepared for the analysis of the beta beryllium phase boundaries in the alloy sy-stems Be - Cu, Be- Fe, Be- Co, and Be-Nb. Uranium Metallurgy. Gamma and beta extrusions were made from the uranium-silicon system for the comparison of textures. An investigation to develop and evaluate arcmelting procedures for producing sound homogeneous thorium-uranium ingots is presented. A program to study the effect of an interdiffusion heat treatment and of subsequent heat treatments upon the corrosion behavior of Zircaloy-2-clad uranium - zirconium specimens containing 7- mil diameter defects extending into the core is reported. A program is presented for cold and warm working of uranium for finishing tube and wire. The apparatus for centrifuging molten uranium within a solid zirconium cladding was put into operation. Work is continuing to develop techniques for making-electron beam- welded aluminum end closures on 25 aluminum-clad uranium core fuel tube irradiation samples. The development of procedures for producing sound dense UC rod materials is reported. Thorium Metallurgy. Data are presented on the effect of water temperature on corrosion rate of thorium alloys. Other Problems. Methods of fabricating semi-finished shapes from arc-melted Y billets were investigated. Work was continued on the multi-temperature extrusion process. (W.L.H.)
