A preliminary calculation of the main thermal and geometrical parameters of the whillspace of the turbine on supercritical carbon dioxide is presented. Turbines of this type are supposed to be used in the Brayton cycle of a nuclear power unit with a liquid metal coolant, the thermal efficiency of which can reach 50%. Calculation of the whillspace of the turbine was carried out using approach generally accepted in practice design of gas and steam turbines. As a result of the calculation, the main characteristics of the stages of the new turbine were obtained. Possible layout of the main thermal power equipment are considered in relation to a power unit with a BN-1200M reactor. On the basis of the performed preliminary calculations, the main determining parameters of the working cycle were obtained in relation to use at nuclear power plants with advanced liquid metal cooled reactor plants. The preliminary assessment of the characteristics of the main heat exchange equipment of the cycle was carried out.
