description: The graduation work analyzes the design features and development trends of intermediate heat exchangers of the integral type, on the basis of which a number of design decisions were made that determine further calculations: the design of the calculated intermediate heat exchanger is straight-tube, the tube bundle tubes are placed in a regular triangle. The main function of the intermediate heat exchanger is to transfer heat between the sodium of the first and second circuits, while ensuring maximum compactness of the heat exchange surface and the absence of cavitation at the suction of the main circulation pump of the primary circuit. To analyze the compliance of the calculated design with these requirements, a thermal-hydraulic calculation was completed, during which the primary coolant flow different nature in different sections of the intermediate heat exchanger was taken into account. The final overall dimensions of the intermediate heat exchanger and the thermophysical properties of the coolants along its course were determined, and the hydraulic pressure losses for each of the coolants were calculated. At the end of calculations, a comparison was made with the data of the existing design of the BN-1200 intermediate heat exchanger and conclusions were made about possible modifications to the calculated design.
