Abstract

Procédé pour la solidification de produits de fission radioactifs. Procédé caractérisé en ce que la solution des produits de fission est transformée en un produit solide à l'aide d'un excès d'un agent de vitrification minéral, à grande surface spécifique et tensioactif. L'invention s'applique à la solidification de produits de fission radioactifs.Process for the solidification of radioactive fission products. Process characterized in that the solution of the fission products is transformed into a solid product with the aid of an excess of an inorganic vitrification agent, with a large specific surface area and a surfactant. The invention applies to the solidification of radioactive fission products.
