Development of a Liquid Breeder Loop for ITER TBM

Korea proposes two DEMO relevant blanket concepts for testing in International Thermonuclear Experimental Reactor (ITER). One is the Helium Cooled Solid Breeder (HCSB) blanket and the other is the He Cooled Molten Lithium/FS(HCML) blanket. KAERI is developing the HCML Test Blanket Module (TBM). The HCML blanket uses He as a coolant at an inlet temperature of 300 .deg. C and an outlet temperature up to 443 .deg. C and Li is used as a tritium breeder. The Experimental loop for Liquid Breeder (ELLI) is being constructed. The main purposes of the experimental loop are to test effect of magneto-hydro-dynamics (MHD) by a magnet field, verify corrosion by a liquid breeder, and confirm the instruments which are used in high temperature environment. As the breeding material in ELLI, Pb-15.7Li, where Li is 15.7 at %, hereafter called PbLi, will be used. The main components for the ELLI were fabricated and experimental loop for testing is being constructed
