Abstract

L'invention a pour objet un procédé de fabrication de pastilles d'oxyde combustible nucléaire. Ce procédé consiste à préparer à partir d'une poudre dudit oxyde des granulés chargés de liant organique, à comprimer ensuite lesdits granulés sous forme de pastilles et à réaliser enfin un frittage desdites pastilles et il se caractérise en ce qu'on prépare lesdits granulés chargés de liant en brassant ladite poudre par un gaz, en pulverisant sur ladite poudre brassée une solution ou une suspension dans un liquide dudit liant organique de façon à obtenir lesdits granulés et en séchant ensuite au moyen dudit gaz les granulés ainsi obtenus. Application à la fabrication d'éléments combustibles pour réacteurs à eau légère.The subject of the invention is a process for manufacturing nuclear fuel oxide pellets. This process consists in preparing from a powder of said oxide granules loaded with organic binder, then compressing said granules in the form of pellets and finally carrying out sintering of said pellets and it is characterized in that said loaded granules are prepared. binder by stirring said powder with a gas, by spraying on said stirred powder a solution or a suspension in a liquid of said organic binder so as to obtain said granules and then drying the granules thus obtained by means of said gas. Application to the manufacture of fuel elements for light water reactors.
