摘要：Nuclear main pumps are one of the most important devices in nuclear plants. Hence hydraulic performances of the nuclear main pump are important. Compared with the traditional speed coefficient method, a revised speed coefficient method is employed to design a nuclear main pump, which is based on the extension chart of the traditional speed coefficient chart. Meanwhile numerical simulations are carried out to examine performances of the designed pump. Results show that performances of the designed pump meet specifications. Clearance leakage causes decrease in head and efficiency of the pump (about 4%). This work provides useful information for the study of nuclear main pumps.
