System for guaranteeing safe operation of steam generator

Abstract

The utility model discloses a system for guaranteeing safe operation of a steam generator, which belongs to the technical field of nuclear power safety, and is characterized in that an outlet of an overheating section of the steam generator is divided into two paths, one path is communicated with an inlet of a steam turbine, the other path is divided into two paths, one path is communicated with an inlet of a condenser, and the other path is communicated with an inlet of a steam-water separator; an outlet of the steam turbine is communicated with an inlet of the condenser, an outlet of the condenser is communicated with an inlet of the deaerator, an outlet of the deaerator is divided into two paths, one path is communicated with an inlet of the evaporation section of the steam generator, the other path is communicated with an inlet of the steam-water separator, and an outlet of the evaporation section of the steam generator is divided into two paths. Wherein one path is communicated with the inlet of the superheat section of the steam generator, the other path is communicated with the inlet of the steam-water separator, and the system can solve the problem that the time for naturally cooling the reactor core after emergency shutdown is relatively long.
