SYSTEM FOR PASSIVE HEAT REMOVAL OF REACTOR PLANT Russian patent published in 2020 - IPC G21C15/00 

FIELD: nuclear energy.

SUBSTANCE: system for passive heat removal of reactor plant includes straight-flow steam generator with steam branch, steam-water injector, heat exchanger located below straight-flow steam generator and connected by supply pipeline with output of steam-water injector, and a discharge pipeline to the inlet of the steam-water injector, a water storage capacity installed above the straight-flow steam generator and connected to it by a water branch with a shut-off valve placed on it, and a starting reservoir. In the passive heat removal system above the water reserve capacity the compensating capacity is installed. Upper volume of vessel is connected to steam branch of straight-flow steam generator with cutoff valve installed on it. Discharge branch of container is located on side surface. On the supply pipeline of the heat exchanger there installed is a check valve, the starter tank is located above the steam-water injector and is connected to the supply pipeline of the heat exchanger, and the branching branch is connected to the supplying branch of the compensating capacity.

EFFECT: invention allows improving reliability of heat removal supplied to steam generator residual heat release in passive mode.
