Summary
Preparation amd properties of UO/sub 2/ containing 5.6 mole % Y/sub 2/O/ syub 3/ solid solution are reported. Calibration of a low-temperature furnace was continued at higher temperature using UO/sub 2/ standard samples of 95% density. A sample of 4 mole% Y/sub 2/O/sub 3/ in UO/sub 2/ was heated without melting to 2650 deg C. It appears that such addition depresses the UO/sub 2/ melting point less tham 100 deg C. A densiiy of 85% of theoretical was obtained in a column of fused UO/sub 2/ powder by ultrasonic vibration. Further investigations are scheduled. samples prepared for autoclave testing at 750 deg F and 1500 psi include as-received stainless tubing, stainless tubing with electron- beam-welded end caps, and pressed UO/sub 2/ core and stainless steel powder end caps. The procedure for preparing UO/sub 2/ irradiation test samples was proof- tested during the period. Data and photographs of yttriumuranium alloys prepared for metallographic inspection and irradiation tests are included. (For preceding period see TID)-5534.) (J.R.D.)
