PASSIVE HEAT REMOVAL SYSTEM Russian patent published in 2021 - IPC G21C15/18 

FIELD: passive heat removal system.

SUBSTANCE: invention relates to a system for passive heat removal from various objects of atomic energy operation. The system contains a heat removal device and an air heat exchanger connected to each other by means of a pipeline for supplying a cooled medium, in the circuit of which a gas trap is installed. The system also contains a pipeline for withdrawing the cooled medium, in the circuit of which an ice condenser with a circulation pump is installed. These pipelines are equipped with active-passive shut-off valves and control valves, a water heat exchanger-aftercooler, an emergency backup feed pump, made with the possibility of operating from a diesel drive, or a pneumatic drive, or a hydraulic drive, or a gas drive, is additionally installed in the circuit of the pipeline for withdrawing the cooled medium, or turbo drive. The ice condenser is equipped with automatic safety devices.

EFFECT: invention increases efficiency of heat removal and the level of autonomy of the passive heat removal system in the event of an accident with a complete blackout and multiple failures of safety systems, ensures an autonomous operation time of at least 72 hours.
