INTEGRATED CIRCUIT OF THERMAL RELIEF OF NUCLEAR REACTOR OF NPP UNIT WITH TURBO PUMPS FOR COOLANT PUMPING Russian patent published in 2018 - IPC G21C1/07 

FIELD: nuclear industry.

SUBSTANCE: invention relates to integrated circuits the nuclear reactor shutdown cooling. Integrated circuit of thermal relief of the nuclear reactor of a NPP unit contains steam turbines, rotating circulating pumps, turbo pumps, three-section steam generators and circulating pumps with electric motors intended for primary start-up of the reactor and for use in emergency situations. Herewith the three-section steam generators contain three separate inlets for the coolant of the first circuit, three heat exchangers and a common outlet for the coolant into the first circuit. In each section of the three-section steam generator heat exchangers are installed, which organize three sub-circuits of the second circuit in the lines of thermal relief. Turbo pumps contain circulating pumps spaced at both ends of the operating shaft of the steam turbine.

EFFECT: technical result is the provision of safe and reliable extraction of the heat load from a nuclear reactor and the highly efficient use of a working medium for the production of electricity.
