核燃料芯块自动装载系统的研制

Research on Automatic Loading System of Nuclear Fuel Pellets

针对核燃料芯块的关键过程生产工序,研制了核燃料芯块横置烧结自动装载系统,设计了具有高可靠性的双胶带芯块输送系统、真空吸取控制系统和芯块计数装置。自动装载能够应用于干法粉末及湿法粉末燃料芯块生产。所生产的芯块外观良好,磨削成品率均在87%以上。系统投入大批量生产应用,运行稳定、可靠。

Aiming at the key production processes of nuclear fuel pellets,this paper develops an automatic loading system for nuclear fuel pellets horizontal sintering,and designs a highly reliable double-belt pellet conveying system,vacuum suction control system and pellet counting device.Automatic loading can be applied to the production of dry powder and wet powder fuel pellets.The produced pellets have good appearance,and the grinding yield is above 87%.The system is put into mass production and application,and the operation is stable and reliable.
