In JAEA, research and development on an Accelerator-Driven System (ADS) have been conducted in order to transmute minor actinides (MA) contained in high-level radioactive wastes. One unit of ADS with thermal power of 800 MW can transmute MA generated in 10 units of light water reactors with electric power of 1 GW. In JAEA, we are studying variety of technical areas such as a superconducting proton accelerator, a spallation target including a beam window and a subcritical core including neutronics design and safety assessment. Moreover, construction of the Transmutation Experimental Facility is being planned as a phase-2 program of the J-PARC project to perform basic experiments for transmutation technology.
