Fabrication techniques were investigated for hot extruded urainum dioxide fuel specimens for irradiation in the VBWR. Honeycomb type ribbon-candy and spiral fuel elements are discussed. The design concepts and model forming are given for the ribbon-candy fuel element. Yttrium fabrication work emphasized the rolling of extruded bar stock into sheet form. Plant designs for the fabrication of ThO/sub 2/ fuel elements containing 5% U/sup 233/ has continued at the experimental leve1. and in studying of metastable reticuloendot -phase uranium-base alloys and the volume instability characteristics of these materials were investigated. The role of intermetallic precipitates in the mechanisms of zirconium alloy corrosion in hightemperature steam was studied. The preparation, reticuloendot -phase boundary study, and thermal analysis of ternary and quaternary beryllium alloys was continued. High-temperature tensile tests were performed on beryllium and Be-8 at.% Ni alloys. (For preceding period see NMI- 2090.) (B.O.G.)
