On the 28 day, according to the official disclosure of the Lanzhou University of Technology, the first domestic 600 ℃ high temperature liquid lead bismuth alloy transmission shielding pump made by the Dalian Sifang electric pump Co., Ltd. was designed and developed by the University's dynamic college. The success of the product has filled the gap in China At present, the product has been tested and commissioned by the Institute of modern physics, Chinese Academy of Sciences, and the relevant technical indicators meet the requirements. Lead bismuth alloy, also known as low temperature alloy or low melting point alloy or fusible alloy. It is mainly composed of lead and bismuth with lower melting point, and other metals are added to regulate the melting point of the alloy. The lead based fast reactor of the fourth generation advanced nuclear energy system is a fast neutron reactor with molten metal lead or lead bismuth alloy as coolant. It uses closed fuel cycle and can operate under the condition of normal pressure and high temperature. The lead based fast reactor has excellent fuel conversion ability, which can effectively improve the utilization of uranium and thorium resources, greatly improve the sustainability of fuel, and can also be used to incinerate long life actinides in the spent fuel of the light water reactor, so that the nuclear energy can be used more cleanly. High temperature liquid lead bismuth alloy delivery pump is the key equipment of the new type minitype nuclear reactor primary loop. In recent years, with the development of national ships and nuclear power equipment, the team has focused on the basic research and product application research and development of nuclear main pump, ship pump, ultra low temperature and special pump. In total, more than 20 papers have been published. Among them, 10 articles are included in SCI and EI. 2 awards are awarded at the provincial level.
