Korea(KO) has developed liquid a breeder blanket and participated in the Test Blanket Module (TBM) program within the International Thermonuclear Experimental Reactor (ITER) with a Helium Cooled Molten Lithium (HCML) concept. To develop the liquid breeder technologies with not only liquid lithium but also lead-lithium (PbLi), an Experimental Loop for a Liquid breeder (ELLI) was constructed at Korea Atomic Energy Research Institute (KAERI). The main purposes of the loop are developing components such as an electromagnetic (EM) pump, testing the effects of magneto-hydro-dynamics (MHD), and investigating the compatibility between liquid breeder and other materials. In the present study, the measurement results of a magnetic field in the fabricated magnet, and a performance test of the EM pump, were introduced in order to validate their designs; the magnet used for the MHD test with a liquid PbLi was designed to produce about 2 T, and the measurement results show that the maximum field was about 2.2 T with a ferritic martensitic (FM) steel channel. The EM pump was designed to circulate the liquid PbLi at up to 60 Ipm, and was tested for up to 11 lpm. The test showed good agreement with the input power to the EM pump.
