As one of experimental facilities of J-PARC (Japan Proton Accelerator Research Complex), we have a plan to construct the Transmutation Experimental Facility (TEF). TEF consists of two facilities: the ADS Target Test Facility (TEF-T) and the Transmutation Physics Experimental Facility (TEF-P). TEF-T equips a liquid lead-bismuth spallation target bombarded by a 400 MeV - 250 kW proton beam in which candidate proton beam window materials are to be irradiated. TEF-P equips a critical/subcritical assembly to investigate physical and dynamic properties of the accelerator-driven system by using a low power (10W) proton beam. Uranium, Plutonium and minor actinide fuels are planned to be loaded into the assembly. Recent progress in R&D efforts toward construction of J-PARC TEF will be presented.
