SHIP NUCLEAR POWER PLANT Russian patent published in 2021 - IPC B63H21/18 G21D1/00 

FIELD: nuclear power plants.

SUBSTANCE: invention relates to ship nuclear power plants. A ship nuclear power plant containing a first circuit, which includes a water-moderated nuclear reactor connected in a closed circuit, a circulation pump of the first circuit, a steam generator and a pressure maintenance system connected to it in the first circuit, and a second circuit, which includes connected between a heating element of the second circuit, located in the steam generator, with a high-pressure turbine and then with a low-pressure turbine, which through the main condenser, condensate and feed pumps and a deaerator is connected to the heating element of the second circuit, characterized in that it contains an additional circuit, consisting of a circulation system, which includes a circulating pump of an additional circuit connected in a closed circuit, a water superheater installed on the steam line between turbines, and an additional heat exchanger for heating water in an additional circuit, placed in at least one steam generator, and heats the water of the additional circuit to the maximum possible temperature, and a pressure maintenance system connected to it in the additional circuit, to prevent boiling of water in the additional circuit.

EFFECT: increasing thermal efficiency of the installation and internal efficiency of the turbine unit by reducing losses from moisture.
