Work was begun on a program to characterize cladding uniformity in relation to the history of the billet core. A demonstration set of unalloyed inner tubes was extruded. Heat treatment and physical metallurgy studies were undertaken for the U-0.3 wt.% Al-0.5 wt.% Si, U-0.3 wt.% Cr-0.3 wt.% Mo, and U- 0.6 wt.% Al alloys. For studying diffusion of magnesium into Zircaloy, sandwich type couples were studied in the hope of eliminating some of the uncertainties inherent in the use of pre-wetted couples. A satisfactory Mg-0.4 wt.% Si casting was made for simular tests to study the diffusion processes. The apparatus for transient zone melting of tubular fuel elements was completed and the initial run was made. Additional billet designs have not eliminated the irregularities found near the outside edge of as-extruded stainless-steel- Zircaloy joints. (For preceding period see NMI-7234.) (auth)
