Since the nuclear reactor coolant pump is the only piece of high-speed rotating machinery in the reactor coolant system,its regular performance is essential to the safety of the entire nuclear power plant.However,China's nuclear power technology development has long faced difficult issues related to the manufacturing process'safety and dependability.Thanks to substantial state funding for funda-mental research and large project promotion,China's third-generation pressurized water reactor's nu-clear reactor coolant pump has been localized with notable success in recent years.From a manufactu-ring and technological standpoint,this study offers a thorough analysis of important parts such as the impeller,pump case,stator,rotor,shielding sleeve,sealing and bearing.It also covers the technical standards for every component as well as material selection,processing processes,assembly process and testing procedures.The paper puts forward pertinent recommendations for the advancement of Chi-na's nuclear reactor coolant pump industry in light of the present situation.
