Technical Report ·
OSTI ID:4152185

Post-extrusion processing of unalloyed U tube No. 54 terminated with its unexpected failure during autoclave testing. Four billets with unalloyed U cores are being prepared for extrusion as natural U prototypes in a program aimed at producing several tubes with 3% enriched cores for irradiation testing at Vallecitos. Individual experimental tubes with cores of U-1 wt.% Si and U-1.5 wt.% Mo are being processed for irradiation. In the program aimed at finding a metastable beta-phase alloy, heat treatment and aging studies were carried out on extruded, cast alloys of two compositions, 0.3 wt.% Cr and 0.3 wt.% Cr-0.3 wt.% Mo. Effort in the stainless steel- Zircaloy joint program was concentrated on fabrication of full-size joints. (For preceding period see NMI-4398.). (W.L.H.)
