It is important to sort out and make available fuel debris information that would be essential for technical development to execute reactor decommissioning (retrieval, criticality safety, etc.). We introduce the significance and present status of analysis on some contaminated samples collected at Fukushima Daiichi Nuclear Power Station Unit 1-3 in a project of “Development of Technology for Fuel Debris Analysis and Fuel Debris Characterization”.
