description: The subject of the graduate qualification work "Modernization of the stator part of the medium pressure cylinder of the steam turbine K-800-23,5" is to perform modernization of the stator part of the CSD, in particular the diaphragms. The thermal calculation of the 2nd stage, the gas dynamic calculation in CFX, the solid model of the guide vane of the new type "singlet" are made. Strength calculations of the diaphragm were performed: elastic calculation, as well as calculation with creep for different materials of the guide vane. The thermal calculation of the 2nd stage, the gas dynamic calculation in CFX, the solid model of the guide vane of the new type "singlet" are made. Strength calculations of the diaphragm were performed: elastic calculation, as well as calculation with creep for different materials of the guide vane. The software packages Ansys Workbench 2023R1 and Microsoft Excel for strength calculations and Siemens NX CAD for building solid models were used for calculations. As a result, all the necessary calculations were made. Based on the results of the strength calculation, an analysis of the reliability and durability with different guide vane materials was performed. The corresponding elements were tested for static strength.
