In these studies, Kyoto University Critical Assembly (KUCA) has been used as sub-critical system connected with the proton beam line from FFAG accelerator facility. A profile of accelerator facility and experimental results, including the first evidence of the transmutation of minor actinides at ADS, will be presented.
