A new method of fuel debris retrieval with geopolymer for Fukushima Dai-ichi NPP (Phase-2)

In this study, an alternative method to retrieve fuel debris and MCCI (Molten Corium Concrete Interaction) products in Fukushima Daiichi Nuclear Power Plants is proposed, where geopolymer is used for semi-stabilization of those debris. Facing the realization of this method, the fluidity and the setting time of geopolymer are regarded as one of the problems. Thus, for investigating and evaluating those properties, slump flow experiment, funnel experiment and viscosity measurement have been done. The re...
