Collection of information on international hot analysis capabilities for the OECD/NEA, preparatory study on analysis of fuel debris (PreADES) project

As part of efforts to further address the Fukushima Daiichi accident, the Organization for the Cooperation and Economic Development Nuclear Energy Agency (OECD-NEA), Committee on the Safety of Nuclear Installations (CSNI) set up a Senior Expert Group (SEG) on Safety Research Opportunities post-Fukushima (SAREF). The SAREF Group received research proposals for international ⁿear-term projects regarding Fukushima Daiichi. One of the major areas of interest was the sampling of fuel debris from Fukushima Daiichi. However, the feasibility in terms of technical details, cost, timing, and logistics of collecting such samples was not known. Thus, a preparatory project collecting, tracking and analysing relevant information on the damaged state, maintaining information channels between CSNI and relevant Japanese organisations, and monitoring the feasibility of extraction, transportation, and examination of such fuel samples was needed
