Abstract
A method for homogenizing plutonia particles in mixed oxide nuclear reactor fuels. The method includes the step of blending urania particles and plutonia particles together and pressing the mixture into a pellet. The pellet is thereafter sintered in a reducing atmosphere with hydrogen present so that pores are formed in the pellet. The plutonia particles are thereby transformed into spherical shells of dense PuO.sub.2-x that surround each pore and which homogenizes the fuel.
