Japan Atomic Energy Research Institute (JAERI) performs research and development for accelerator-driven transmutation systems to improve the environmental impact and increase a capacity of waste disposal plant. The system consists of a superconducting proton LINAC, Pb-Bi eutectic spallation target and Pb-Bi cooled subcritical core. Thermal output of the system is 800MW by injection of the proton beam with the power of 20 to 30MW and then, about 250kg of minor actinides can be transmuted annually. To study and evaluate the feasibility of ADS by a physical and an engineering viewpoint, the Transmutation Experimental Facility is proposed under a framework of J-PARC project. In the presentation, the R&D activities by the contract between the Ministry of Education, Culture, Sports, Science and Technology will be presented.
