For a dedicated transmutation system, Japan Atomic Energy Agency (JAEA) has been proceeding with the research and development (R&D) on an accelerator-driven subcritical system (ADS). JAEA has started a comprehensive R&D program since the fiscal year of 2002 to acquire knowledge and elemental technology for the validation of engineering feasibility of the ADS. In this paper, the outline and the results in the first three-years stage of the program are reported. For R&D on accelerator, a prototype cryomodule was built and its good performance in electric field was examined. For R&D on LBE, various technical data for material corrosion, thermal-hydraulics and radioactive impurity were obtained. For R&D on subcritical core, engineering feasibility for the ADS was discussed using thermal-hydraulic and structural analysis not only in normal operation but also in transient situations. Reactor physics experiments for subcritical monitoring of ADS were performed at critical assemblies.
