TRUSS CONSOLE OF MELT LOCALIZATION DEVICE (OPTIONS) Russian patent published in 2023 - IPC G21C9/16 

FIELD: nuclear industry.

SUBSTANCE: melt localization devices (hereinafter referred to as MLDs), equipped with a vessel for receiving and distributing the melt, in particular mechanisms that ensure the preservation of the structural integrity of the MLDs during severe accidents. The truss console of the melt localization device contains external, internal parallel and radial sectors, consisting of parallel, radial force ribs, external, middle, internal shells, an upper force plate, a lower force plate. Radial power ribs have holes in which a manifold is installed, to which at least one pipe (26) of the first group is connected, passing through a hole in the outer shell of at least one of the outer parallel or radial sectors, pipes of the second group connecting the manifold with the holes in the upper power plate, pipes of the third group, passing through the middle and inner shells and exiting from the inside of the inner shell. The flow area of the collector is greater than the sum of the flow sections of the pipes of the second and third groups.

EFFECT: improving the reliability of the melt localization device.
