Abstract: Recent activities on reactor physics experiment for advanced nuclear reactor systems using the Kyoto University Critical Assembly (KUCA) are described and reviewed. The activities include 1) benchmark experiments for high burnup next generation reactor fuel, 2) basic experiments on thorium fueled reactor, and 3) experiments on ADS using high-energy proton accelerator and subcritical cores. These experiments are mainly aimed at verification and validation of current methodology for nuclear characteristics design, and also aimed at development of experimental techniques.
