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) andthermal fluid (JLBL-3)
• Proton irradiation depended on SINQ atPSI(STIP & MEGAPIE).

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.
