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.
