Nuclear data is very important for the physics event relevant to the intermediat energy interactions for ADS. Research activities relevant to nuclear data are highlighted in light of experimental measurements and theoretical prediction method development. Major focus of data need research has been on the data at the high-energy region above 20 MeV up to several GeV. Present fundamental data belong mainly to special elements and isotopes, such as 208Pb Nuclear data is very important for the physics event relevant to the intermediat energy interactions for ADS.
