Honeycomb-type Fuel Elements. An Al-clad Al--16 wt% U plate with 36 Al-- 0.8 wt% Mg core inserts was rolled. The equipment for punching fuel plates and plugging the holes with core inserts is described. Attempts to form the fuel plate into a spiral are described. Yttrium Fabrication. The results of extrusion of Y billets and tube drawing and swaging experiments are reported. Metallographic examination of Zircaloy-2-clad Y after heat treatment at 900 and 1000 deg C for times up to 225 hr gave no evidence of ZircaloyY reaction. U/sup 233/ Recycle. The conclusions reached by a series of meetings on problem areas are briefly summarized. They treat input fuel shipment, fuel shielding, and fuel allocation of core loadings for efficient use of irradiated U/sup 233/. Hydrostatic Fabrication. The results of extrusion of Be billets into rods, using water as the pressure medium, are reported. Corrosion of Zirconium Alloys. The behavior of Zr intermetallic compounds with H/sub 2/ and O/sub 2/ is described. Oxygen gradients in corroding Zr alloy samples exposed to steam were investigated. Crack formation in the oxide films was studied. (D.J.C.)
