Abstract

Procédé de fabrication de combustibles nucléaires PuO2 /UO2 . Un mélange de poudre PuO2 /UO2 est broyé, pressé, granulé et fritté et, après nouveau broyage et pressage, il est granulé. Ce produit intermédiaire est entreposé et en fonction des besoins il est converti avec une quantité appropriée de granulat de UO2 de la manière usuelle en corps combustibles nucléaires. Les deux granulats doivent posséder autant que possible une même densité, forme de grain et capacité de frittage.
