By introducing an induction heater and combination of a compact heat exchanger and a helium loop as a cooler, high temperature operation of lithium-lead loop at Kyoto University was performed successfully. After modification of thermal insulation, reasonable temperature distribution was obtained and sufficient effective heating power of 2.7kW and heating efficiency of 40% was demonstrated without concern about overheating of downstream of the high temperature section. As a result, observed highest temperature is 926°C and 4 hours continuous operation above 900°C was achieved.
