SYSTEM FOR PRESSURE REDUCTION IN THE HERMETIC SHELL, RECHARGE OF THE REACTOR PLANT AND THE SPENT FUEL POOL Russian patent published in 2023 - IPC G21C15/18 

FIELD: nuclear power engineering.

SUBSTANCE: invention relates to heat exchange technology and can be used as a system for normal and emergency heat removal from the containment of a nuclear power plant. The pressure reduction system in the hermetic shell contains an external protective shell, an internal protective shell with a cooling medium spray system placed in it, connected by means of pipelines and fittings to the storage capacity of the coolant and control and measuring devices. Moreover, the storage capacity of the coolant is made in the form of several pipes connected by a common collector, the pipes are placed in the inter-shell space on support devices or consoles mounted on the inner surface of the external protective shell or on the outer surface of the internal protective shell. These pipes, support devices or consoles are installed parallel, or at an angle, or perpendicular to the base plane of the external and internal protective shells and are equipped with damping devices.

EFFECT: increase in the reliability of the reactor plant and the protective shell of the nuclear power plant.
