Abstract:A multi-disciplinary optimization software Isight and CFD simulation
   software NUMECA were used to integrate the optimization strategy,
   numerical experimental design, approximation model and global
   optimization algorithm into one design platform. The user interface was
   created by Python. The automatic optimization design platform suitable
   for a hydraulic model of nuclear reactor coolant pump has been
   established. Based on the model pump obtained by our research group in
   preliminary studies, the automatic optimization design platform was used
   to establish the approximation model, and it can reflect the
   relationship between design variables and the objective function. Then
   the impeller and impeller-guide vane interaction was studied.
   Multi-island genetic algorithm was used. A pump model with improved
   hydraulic performance was obtained. The results show that the initially
   built integrated optimization platform is of applicability. The
   feasibility of the optimization strategy has also been verified.
