Alternative retrieval method (Innovative Approach) without submerging PCV with water is deemed necessary and so stipulated in the Mid-to-Long-Term Roadmap by Japanese Government. Method without submersion → Request for Information (RFI) on the Innovative Approach of Fuel Debris Retrieval and relevant technology that supports the Innovative Approach was performed by METI through the IRID. About 200 pieces of information were received from Japan and overseas countries. In reference to RFI results, this project is aimed at the conceptual study of Innovative Approach to retrieve the fuel debris without submerging PCV with water and the feasibility study of essential technologies to support the Innovative Approach.
