Abstract Based on self-design of impeller of AP1000 nuclear main pump,the upright guide vane was designed using foundational hydraulic methods. In order to reduce the hydraulic loss in the vane flow passage, two different schemes were proposed to optimize the vane design after analyzing the CFD computational results. The first one was to directly optimize the upright guide vanes design. And the other was to redesign the upright guide vanes as twisted spatial type to match up the impeller and subsequently to optimize the vanes. In the space guide vanes design and optimization process, two different solutions were adopted to parameterize the model, and the sample database were generated. With the hydraulic efficiency of impeller and guide vane being selected as the optimization objective, ANN and genetic algorithms were used to repeatedly optimize the blade profile of space guide vanes, and finally the guide vanes were obtained with better hydraulic efficiency matching with the impeller. The influence of different numbers of guide vane on the hydraulic efficiency was also discussed to provide the theoretical guidance and reference in hydraulic performance.

Key words： nuclear main pump model pump guide vanes design parameterized optimization numerical simulation
