description: In this paper, the NPP feed pump will be considered, in which it is necessary to design the first stage of the impeller with the required cavitation qualities. To achieve this goal, several stages were performed: calculation of the flow part, determination of the main dimensions, design of the flow part of the pump stage, calculation of energy and cavitation characteristics, numerical study of the viscous flow of the working fluid, analysis of the results obtained. In the process of work, the design methodology and instructions for the hydraulic calculation of the flow part of the centrifugal pump were applied by S. A. Gorgidzhanyan. Theoretical knowledge about the phenomenon of cavitation and practical skills in applying modern methods of computational fluid dynamics were also obtained. As a result of the work, the flow part of the first stage of the pump will be calculated and designed, energy characteristics are obtained, and recommendations for further design are given.
