Abstract

After the Fukushima nuclear accident, reduction of radioactive wastes got much attention. To reduce the burden of radiological nuclides contained in spent nuclear fuel, Partitioning-Transmutation (P-T) technology is noted at the discussion of the national fuel cycle policy. By using P-T technology, radiological hazard can be reduced less than 1/100. As for the system for effective transmutation, an accelerator-driven system is desirable as a dedicated transmutor. To perform basic studies for accelerator-driven system, Japan Atomic Energy Agency has promoted design of the Transmutation Experimental Facility (TEF) within the framework of the J-PARC project. A lead-bismuth spallation target, which is bombarded with 400 MeV - 250 kW protons, and a low-power subcritical reactor will be installed in the facility. We will start construction within few years after a national review of TEF.
