To perform the research and development for accelerator-driven system (ADS), Japan Atomic Energy Research Institute (JAERI) plans to build a Transmutation Experimental Facility under the JAERI-KEK joint J-PARC program. Transmutation Experimental Facility consists of two buildings, Transmutation Physics Experimental Facility to make reactor physics experiment with subcritical core, and ADS Target Test Facility for the preparation of irradiation database for various structural materials. In this report, purpose to build, experimental schedule, and design study of the ADS target test facility with drawer type spallation target are summarized.

The construction of Transmutation Experimental Facility (TEF) is planned under the framework of Japan Proton Accelerator Research Complex (J-PARC) project. A liquid lead-bismuth (Pb-Bi) spallation target with beam power of 600MeV-200kW will be installed into the TEF. Analyses were performed to determine the effective thickness of biological shield for Pb-Bi target by using both MCNPX and ATRAS code system. Thickness of around 6m should be required to decrease the radiation level. The streaming analyses through the proton injection beam duct and the primary cooling circuit piping were also performed. The result of the beam duct streaming shows good agreement between the results of MCNPX and DUCT-III. The additional shield must be installed to suppress the activation of accelerator components. In the case of streaming through the primary cooling circuit piping, it is proved that the radiation level at the exit of the shield is allowable. The radiation level can be much more reduced by optimizing the bending position and length of the piping.

Study of liquid lead-bismuth (Pb-Bi) technology is performed at JAERI. Pb-Bi cooled ADS has favorite neutronic performances rather than that of sodium-cooled ADS. In order to develop an ADS, JAERI has proposed a transmutation experimental facility which consists of a 600 MeV-200 kW Pb-Bi spallation target and a fast critical assembly with a spallation target within a framework of the high intensity proton accelerator project. In the viewpoint of engineering application of Pb-Bi, there is a key technology, which should be proven before the construction of TEF. They are materials issues and handling techniques of flowing eutectic Pb-Bi. To control these technical issues, we proceed two experimental studies with the material corrosion test device and the liquid Pb-Bi loop.
