Technologies are required to stabilise and solidify fuel debris and contaminated water present inside the Primary Containment Vessel (PCV) of the Fukushima Daiichi Nuclear Power Plant. In this study, metakaolin, a representative reactive filler, was investigated by comparing the specifications and properties of commercially available products before and after hardening. In addition, with consideration of a stable supply of raw materials, domestically produced metakaolin was manufactured and its properties were systematically evaluated.
