FIELD: nuclear power engineering.
SUBSTANCE: proposed nuclear power plant incorporates indirect-contact liquid metal-to-gas heat exchangers. Gas outlets of heat exchangers communicate with inlets of gas turbines. Gas outlets of the latter communicate with gas inlets of gas-to-water heat exchangers. Steam lines passing steam obtained to user are connected to steam turbines provided with pumps. At least one gas turbine is coupled through shaft with at least one of these pumps and/or heating-medium passages are provided in steam turbines. These passages communicate at inlet end with gas outlet of at least one of gas blowers. Gas used for the purpose may be nitrogen, air, helium, carbon dioxide, or mixtures thereof. Nuclear reactor is provided with filters for cleaning liquid metal cooled down in heat exchangers. Guide-vane apparatus of steam turbine and/or turbine wheels are provided with heating medium passages. Hot gas for steam reheat is used as heating medium. Inlets of these passages communicate with gas outlet of at least one of gas turbines and their outlets, with gas blower inlet. In this way thermal efficiency of proposed nuclear power plant is enhanced by 50%.
EFFECT: enhanced thermal efficiency of nuclear power plant.
