    To provide a radioactive waste solidification method or the like capable of efficiently performing solidification treatment.SOLUTION: In a method for solidifying radioactive waste according to an embodiment, a kneaded material forming step is provided, and the radioactive waste containing an ion exchange resin is solidified and processed. In the kneaded material forming step, the kneaded material is formed by kneading the radioactive waste, a hydraulic inorganic solidifying material, a water reducing agent and kneading water. The water reducing agent is a naphthalenesulfonic acid system. In the kneaded material forming step, 0.6 parts by weight or more of the water reducing agent is added to 100 parts by weight of the hydraulic inorganic solidifying material.SELECTED DRAWING: Figure 2

    【課題】固化処理を効率的に実行可能な放射性廃棄物固化方法等を提供する。【解決手段】実施形態に係る放射性廃棄物の固化方法では、混練物形成工程を有し、イオン交換樹脂を含む放射性廃棄物について固化処理を行う。混練物形成工程では、放射性廃棄物と水硬性無機固化材と減水剤と混練水とを混練することによって混練物を形成する。減水剤は、ナフタレンスルホン酸系である。混練物形成工程では、１００重量部の前記水硬性無機固化材に対して、０．６重量部以上の減水剤を添加する。【選択図】図２
