description: The topic of the final qualifying work: "Modernization of the IPC of the K-800-23,5 steam turbine". The present work is devoted to the formation of the mathematical apparatus and principles of design of reactive HPC and IPC of steam turbines, the development of a variant of a reactive IPC for the potential retrofit of IPC K-800-23,5, the analysis of modern methods to improve the efficiency and performance of steam turbines in operation. The final qualifying work consists of an introduction, 6 sections, a conclusion and appendices. The first section "Reactive-type steam turbines" is devoted to the review and analysis of the design of existing high-power reactive turbines. The second section "Overview of the IPC of the K-800-23,5 steam turbine unit" presents the characteristics of the IPC of various versions of the K-800-23,5. The third section "Design of the flow part of the IPC" formulates the basic principles of design calculation and mathematical apparatus. The fourth section "Strength substantiation of the main structural elements of a reactiveÂ  IPC" demonstrates an analysis og the strength of critical parts of the designed IPC.The fifth section "Coupled gas dynamic and strength analysis of the first stage" is devoted to the joint study of the characteristics of the stage. The sixth section "Retrofit approaches of reactive IPC" provides modern methods for improving the efficiency and productivity of the IPC of reactive steam turbines.
