Technical Report ·
OSTI ID:4150281

Two tubes with cores of 3% enriched, unalloyed U are being prepared for irradiation testing at VBWR. Postextrusion processing of the two full-size tubes with experimental alloy cores was discontinued because of defects. Work in the program to find metastable beta-phase alloys of U was concentrated on four compositions: U-0.3 wt.% Cr. U-0.3 wt.% Cr-0.3 wt.% Mo, U-0.3 wt.% Cr-0.4 U.% Si, and U-0.4 wt.% Si-0.4 wt.% Al. An intensive program of rod extrusion was carried out in an effort to define conditions for extrusion of tubular stainless steelZircaloy joints having adequate strength and corrosion resistance. (For preceding period see NMI-7222.). (W.L.H.)
