description: This paper provides a justification of the hydrodynamic stability of the steam generator of the BREST-OD-300. The issue of hydrodynamic instability has been studied, the main factors in the occurrence of hydrodynamic instability and ways to overcome it have been determined. The design of the steam generator BREST-OD-300 has been studied and its features have been highlighted. A thermal calculation of a once-through steam generator producing superheated vapour was carried out, which resulted in the determination of the heating surface and the length of the heat exchange pipes. During the hydraulic calculation, the pressure loss along the secondary circuit was determined and the boundaries of the hydrodynamic stability of the steam generator were obtained based on the results of the constructed hydrodynamic characteristic. The results obtained were analyzed.
