description: In this work, thermohydraulic, strength, and economic calculations of a thermal deaerator of increased pressure were performed. The deaerator was developed on the basis of already proven design solutions and techniques. The tank from the highâpressure deaerator used at the Kudankulam nuclear power plant (hereinafter referred to as the NPP) and the deaeration column of the deaerator used at the Leningrad NPP 2 were selected as the reference parts of the deaerator. The thermohydraulic calculation showed that the developed deaerator is hydrodynamically stable and provides the necessary heating of feed water. The steam velocities in the column, as well as the bubbling device, are within acceptable limits, which prevents moisture entrainment, and also reduces hydraulic pressure losses. As a result of the strength calculation, the reliability of the structure under working loads was proved. A comparison of two structural materials was also made, which revealed the advantage of steel 09G2S, which consists in the possibility of reducing the thicknesses of the main elements of the deaerator. During the economic calculation, the approximate total savings on the weight of rolled products were calculated when choosing steel 09G2C for the manufacture of the main elements of the deaerator.
