To improve the design speed and reduce cost for previous blade method, a modified inverse method is presented. In new after series of physical mathematical simplifications, sail-like constrained area proposed, which can be used to configure different runner shapes. Then, applied redesign optimize scale core component 1400-MW canned nuclear coolant pump in an established multi-optimization system compromising Computational Fluid Dynamics (CFD) analysis, Response Surface Methodology (RSM) Non-dominated Sorting Genetic Algorithm-II (NSGA-II). After execution optimization procedure, three optimal samples were ultimately obtained. through comparative analysis using target blade, it was found that maximum efficiency improvement reached 1.6%, while head about 10%. Overall, promising will benefit hydraulic mixed-flow has been proposed.
