The results of work indicate that fused UC/sub 2/ powder has the best properties for obtaining densities above 92% of the theoretical value by hot isostatic pressing techniques without pleating of the cladding. A sample with the highest compacted density obtained was made by using a blend of 75% coarse fused UC/sub 2/ and 25% fine ceramic UO/sub 2/ powders. Thermal cycling duta are presented for several U--Y alloys that were cycled 500 times between 725 and 225 deg C. The effect of compacting pressure on green strength density of 65U--35Y alloys is reported. Data are reported on the thermal conductivities of U--Y alloys. Attempts to prepare UO/sub 2/--Y/sub 2/O/sub 3/ to above 90% of theoretical density were continued. A sample of UO/sub 2/--Nb/sub 2/O/sub 5/ was prepared to 92% of theoretical density. Data are presented on the thermal expansion, steam corrosion, and elastic modulus and compressive strength of UO/ sub 2/, UO/sub 2/ --CeO/sub 2/, UO/sub 2/ --U/sub 2/O3, and UO/sub 2/ --Nb/sub 2/ O/sub 5/. Thermal expansion, steam corrosion, and elaatic modulus data are reported for Tho/sub 2/ --UC/sub 2/ systems. (W.L.H.)
