description: This paper provides a justification for the power control program of the SMR NPP. The design of the RITM-200 steam generating unit and possible reactorâs power control programs were studied. A thermal calculation of a straight-tube steam generator producing superheated steam was made, which resulted in the determination of the heating surface and the length of the heat exchange tubes. During the hydraulic calculation, pressure losses in the secondary circuit were determined and the need to install a throttle washer at the inlet to the steam generator to prevent the occurrence of hydrodynamic instability was assessed. The thermohydraulic calculation of the steam generator was made at a power of 90% of the nominal. The influence of the feed water consumption in the steam generator on the power of the reactor plant and the quality of the generated steam is estimated. For the selected geometry of the tube bundle and the steam header, a strength calculation was made. Based on the calculation results, a joint static characteristic of the reactor and steam generator was constructed. The obtained results were analyzed, and the obtained results were compared with the results of other authors.
