In investigations on phase relations of UO/sub 2/ - ZrO/sub 2/ - CaO and U0/sub 2/ - CeO/sub 2/ systems, the emphasis during the report period was on aspects of hydrogen sintering and the effects of this method on composition limits for the single-phase face-centered cubic region. Argon sintering evaluations were also made. Results indicate that 1800 deg C is required for production of single-phase solid solutions. In thermal shock resistance studies, vapor-deposited W metal on the inner surface-of pellets did not react with ZrO/ sub 2/ at 2000 deg C, however cracks developed at 800 to 1000 deg C. Corrosion tests of CaO stabilized ZrO/sub 2/ conthining U0/sub 2/ in water are being conducted, and methods for determining U0/sub 2/ content in fuel samples are being developed. (J.R.D.)
