This critical assessment of the ThO/sub 2/-UO/sub 2/ pellet fuel technology was conducted in support of the Fuels Refabrication and Development Program (FRAD). Included in this critical review are the following areas: powder preparation; pellet fabrication; fuel chemical, physical, and mechanical properties; and fuel irradiation performance. The authors identify (1) areas where data are either deficient or lacking and (2) requirements for additional development and experimental work.
