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).

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.
