ABSTRACT:
A mixed oxide fuel of uranium dioxide and plutonium dioxide is in the form of mixed oxide particles with a diameter of 0.2 to 2 mm. A surface layer of the particles consists of UO.sub.2 with a plutonium content per unit of volume of at most 15 per cent of the average plutonium content per unit of volume of the particle. The particles are formed by extrusion through a concentric nozzle. A water emulsion of uranium dioxide is first pumped through the inner nozzle, after which a water emulsion of plutonium dioxide is pumped through the outer nozzle. Thereafter a water emulsion of uranium dioxide is pumped through the outer nozzle to surround the plutonium dioxide layer and then water emulsion of uranium dioxide is pumped through the first nozzle to complete the enclosure of the plutonium dioxide.
