  • Production process of a composite nuclear fuel material composed of (U, Pu)Oaggregates dispersed in a UOmatrix
    Patent number: 6984344
    Abstract: The invention relates to a production process of a composite material composed of aggregates of a blend of UO2 and of PuO2 dispersed in a UO2 matrix comprising the steps of dry co-grinding of a UO2 powder and of a PuO2 powder in order to obtain a homogenous primary blend, of consolidating the primary blend in order to obtain cohesive aggregates, of sieving the aggregates in a range of 20 to 350 ?m, of diluting the sieved aggregates in a UO2 matrix in order to obtain a powder blend, of pelletising the powder blend and of sintering the pellets obtained in order to obtain the composite.
