  4. ADS Target test facility • LBE spallation target test had planned in J-PARC phase II program. • LBE controlling techniques acquisition was a goal of R&Ds. • LBE loops were run for corrosion-erosion (JLBL-1), target model (JLBL-2) and thermal fluid (JLBL-3) • Proton irradiation depended on SINQ at PSI(STIP & MEGAPIE). 10 th OECD NEA Meeting on AFPP and T, Mito, 2008

  19. Achievements of our Practice • Proton irradiation Data base for austenitic steel have been obtained up to 20 dpa, which included mechanical property and micro-nano structure. • JLBL-1 Materials property under LBE flow was obtained through 18000 hrs run. Oxygen sensor property and performance of EMP were investigated. • JLBL-2 EMP drove LBE in the coaxial counter flows. EMF performance was investigated. Ultrasonic Doppler prove visualized LBE flow. • JLBL-3 Massive flow control was experienced (500L/min). Heat transfer coefficient of the beam model was formulized. 10 th OECD NEA Meeting on AFPP and T, Mito, 2008
