Labor Consuming

One of the important joints of a liquid metal fast reactor is the main circulation pump. In the course of the present research, a preproduction model of the pressure chamber, the most labor-consuming unit of the main circulation pump, was manufactured. This complex welded structure was made of 10Kh15N9S3B3 (EP-302Sh) steel sheets; fixtures and accessories were also manufactured, and as a result the metal consumption of the structure decreased. Technological documentation was made for bending, stamping of parts of the pressure chamber, welding of components, their heat and mechanic treatment, and its assembling. According to the results of this work, the existing technological documentation was adjusted in the context of the new data for pressure chamber of the main pump.

In the presented work, a new version of the design of the flow-through part of the main circulation pump for NPPs with increased energy indices is proposed. This design solution allows to increase the efficiency of the pump from 82 -83% to 88-89%. Numerical hydrodynamic calculations of the viscous fluid flow in the ANSYS CFX environment of various variants of the pump design have been performed: a spherical chamber with guide vanes, a spiral tap, a spiral tap with discharge openings in a spherical chamber (new design). As a result of the hydrodynamic calculations, the values of the hydraulic efficiency of the variants considered were obtained. As a result of the analysis of the pattern of the flow of the investigated variants, it is established that the proposed version of the pump with unloading holes has additional hydraulic losses due to circulation of the flow through them. The value of the circulation of the flow through the discharge openings is numerically obtained. The cause of the detected effect was investigated. As a result of the conducted research it is established that it is possible to further increase the efficiency of the proposed pump design by optimizing the geometry of the discharge openings.
