The effects of ballmilling time(0 ~4 hrs) have been investigated on the change of powder characteristics, compaction behavior (compaction pressure range : 200 ~400MPa) and sinterability (1700'c in Ha atmosphere) of two different UO powders (exADU and exAUC) prepared by the wet process. It is observed that, while the exADU UO was little affected, the exAUC UO was largely affected by the ...
