  • Method for solidifying radioactive waste
    Patent number: 12142388
    Abstract: This invention relates to a solidifying agent for solidifying radioactive waste, and more particularly to a solidifying-agent composition for solidifying radioactive waste, including alumina cement and a gypsum powder. The solidifying-agent composition including alumina cement and a gypsum powder is capable of effectively minimizing an increase in the volume of a solidified radioactive waste product to a level satisfying physical and chemical safety regulations upon the solidification of radioactive waste.
    Type: Grant
    Filed: November 2, 2021
    Date of Patent: November 12, 2024
    Assignee: Kepco Nuclear Fuel Co., Ltd.
    Inventors: Nam-Chan Cho, Young-Jong Ju, Jeong-Myeong Kim, Dong Han Lim, Kyoung Kuk Ki, Jung Hoon Park
