Technical Report ·
OSTI ID:4163714

Four Vallecitos prototype tubes of unalloyed U were extruded. Two full- size tubes with cores of U-1 wt.% Si and U-1.5 wt.% Mo, respectively, are being processed for irradiation testing to permit comparison of swelling behavior with that of U-2 wt.% Zr. The work on two Al alloys, U-0.2 wt.% Al and U-0.5 wt.% Al, is concentrating on suitable methods for grain refinement. Work on metastable beta-phase U alloy has progressed through the stage of extrusion and evaluation of rods of four promising compositions. Several 4-inch-diameter tubular stainless steelZircaloy joints were extruded. (For preceding period see NMI- 7221.). (W.L.H.)
