SYSTEM FOR PASSIVE HEAT REMOVAL OF REACTOR PLANT Russian patent published in 2021 - IPC G21C15/18 

FIELD: heat exchange.

SUBSTANCE: invention relates to a system of heat removal from a reactor plant, in particular, in systems of emergency cooling of active zones of nuclear reactors without consumption of external energy sources. System includes steam generator with steam and water branches, steam-water injector, heat exchanger located below steam generator and cooled by final heat absorber, water storage tank installed above steam generator and connected by water branch with cut-off valve arranged on it to steam generator, supplying branch to supply pipeline of heat exchanger, and its upper volume is connected by additional branch to steam branch of steam generator, starting reservoir arranged above steam-water injector and upper part connected by supplying branch to supply pipeline of heat exchanger. At that, steam generator water line is connected to water storage capacity side surface in point at level corresponding to horizontal level of steam-water injector arrangement, and additional branch of water storage capacity is connected to steam branch of steam generator in point of connection of steam branch to input into steam-water injector.

EFFECT: technical result of the passive heat removal system is increase in the level of reliability and duration of discharge of residual heat emissions supplied to the steam generator after the heat exchanger in passive mode for an unlimited period of time in the absence of external power sources and higher safety of the reactor plant operation.
