  • Patent number: 12176120
    Abstract: The present invention provides a method for synergistically vitrifying medium and low-level radioactive glass fibers and combustible solid nuclear waste incineration ashes. According to the chemical composition characteristics of incineration ashes of combustible solid wastes such as glass fibers, cotton, plastic, rubber and absorbent paper produced during the operation of nuclear facilities, the present invention takes the glass fibers as a glass matrix of combustible waste incineration ashes and minimizes the addition of an additive by a combination in different proportions through a synergistic treatment method. A vitrified form provided by the present invention meets the requirements of uniformity, density, impact resistance, chemical durability and the like of radioactive waste vitrified forms.
    Type: Grant
