The influence of the properties and the treatments of UO2 and ThO2 powders on the preparation of a double pellet composed by UO2 inner core and ThO2 outer hollow cylinder was studied. Although a simultaneous pressing-sintering process is preferable due to its relative simplicity and quickness, good (uncracked) double pellets were manufactured only by a two-step separate UO2 and ThO2 pressing and sintering. Different shrinkage kinetics of the two components are responsible for this behaviour.
