Disclosed is a method of disposal of metallic aluminum-containing solid waste comprising the steps of reacting radioactive solid waste containing metallic aluminum with an alkali solution to generate a hydrogen gas and then mixing the resulting reaction liquid with a solidifying material containing a latent hydraulic material as a main component to solidify the liquid. According to the method of the invention, solidification of aluminum-containing radioactive solid waste in a highly filled state (high concentration) is feasible and a solid having excellent mechanical strength and properties of preventing oozing of radioactive nuclide can be obtained.
Méthode d'élimination de déchets solides contenant de l'aluminium métallique. La méthode consiste à faire réagir des déchets solides radioactifs contenant de l'aluminium métallique dans une solution alcaline afin de produire de l'hydrogène gazeux, puis mélanger le liquide de réaction obtenu avec un agent solidifiant comprenant un matériau hydraulique latent utilisé comme élément principal pour la solidification du liquide. Cette méthode permet de solidifier un déchet solide radioactif contenant de l'aluminium en un produit très dense (concentration élevée), on peut donc obtenir un solide ayant une excellente résistance mécanique, qui a la propriété d'empêcher le suintement de radionucléides.
