Simulated fuel debris in RPV and CV containing uranium were fabricated by light-concentrating heating technique, respectively, to provide them for cutting tests with disc cutter. Characteristic data such as bulk density, microstructure, formed phases and micro-hardness on cross-section were obtained.
