The outcomes of gas-dynamic computations for the low-pressure cylinder component of the K-1000-60/1500-2M type low-speed steam turbine intended for use in nuclear power plants are presented in the paper. Various strategies for enhancing the low-pressure cylinder, incorporating a novel approach, which was not previously employed in low-speed high-power steam turbines, have been identified. The flow part redesign has been carried out through the comprehensive methodology and software imple-mented in the IPMFlow package. This methodology encompasses gas-dynamic computations of varying complexities and ana-lytical profiling methods for spatial blade row shapes based on a limited set of parameterized values. Real thermodynamic prop-erties of water and steam were considered in 3D turbulent flow calculations. The final stage involved end-to-end 3D computations of the 7-stage low-pressure cylinder, employing parallel computing technology. The results indicate that the innovative solutions incorporated in the developed low-pressure cylinder led to a substantial increase in both efficiency and power.
