description: The topic of the final qualifying work: "Determination of cavitation characteris-tics of the control valve DN 400 for nuclear power plants".The process of introducing equipment into production is associated with determining the boundaries of its applicability. Nowadays, this task is increasingly entrusted to the methods of software modeling, instead of testing on experimental devices.This work is devoted to the determination of the cavitation and flow characteristics of the control valve DN 400 (RC 110.400.00-E) by the modeling method using the Ansys Fluent software.The paper presents analytical calculations of the claimed characteristics and compares their results with the results obtained during modeling.Based on the simulation results, the pressure drop was determined, which ensures the cavitation-free operation of the valve, and a solution was proposed aimed at making the flow characteristic more linear. The analysis of the most vulnerable to the destructive effects of cavitation surfaces is carried out.
