The reporter recently learned that the liquid metal lithium experimental loop developed by the project team of the Institute of Nuclear Energy Safety Technology, Hefei Institute of Material Science, Chinese Academy of Sciences, achieved the first ultra-high temperature stable operation at 1500K (equivalent to 1227 degrees Celsius) for 1000 hours in China, marking China's advanced nuclear energy system New breakthroughs have been made in the key technologies of liquid metal coolants. During the development process, the project team overcame the difficulties of structural stress coordination, immersion measurement and flow stability control of the device under ultra-high temperature liquid lithium working fluid environment. At present, the circuit has carried out a series of high temperature refractory alloys in the 1400K to 1500K temperature zone flowing lithium environment corrosion resistance research experiments, high temperature operation performance has reached the international leading level, for ultra-high temperature liquid lithium and structural materials compatibility The research provides an important experimental platform. It is reported that liquid lithium or lithium alloy can be used as a coolant in the nuclear fusion reactor to export the heat generated by the reactor. It has the advantages of high working temperature, good thermal conductivity, and low density. Due to the high boiling point of liquid lithium, the system can be operated at atmospheric pressure. The use of lithium and other coolants can make the reactor system smaller and lighter. Therefore, it is the main coolant material for high power space reactors and future fusion reactors.
