To meet this objective, batches of ThO/sub 2/ powders were compared and milling parameters, pressing and sintering conditions were established. A method for blending ThO/sub 2/ and UO/sub 2/ into homogeneous powders that press and sinter into 95% TD pellets was determined. The effect of UO/sub 2/ additions on ThO/sub 2/-UO/sub 2/ pellet properties was determined and a process for fabricating irradiation test quality ThO/sub 2/-20 wt% UO/sub 2/ pellets containing CaO as a dissolution aid was established.
