LIQUID METAL COOLED NUCLEAR REACTOR (VERSIONS) Russian patent published in 2014 - IPC G21C1/00 

FIELD: physics.

SUBSTANCE: liquid metal cooled nuclear reactor has a housing with a separating shell inside. At least one steam generator and one pump are mounted in the annular space between the housing and the separating shell. Inside the separating shell there is a core, above which there is a hot header linked to the steam generator in its middle part in order to split the stream of liquid metal coolant into an ascending stream and a descending stream, or the hot heading is linked to the steam generator at its top part to facilitate counterflow heat exchange. Under the cover of the reactor there is an upper horizontal cold header with free coolant level, and under the steam generator there is a lower collection header linked to the upper cold header. The input of the pump is connected to the upper cold header and the output of the pump is connected to a lower annular pressure header, wherein the headers are divided by a horizontal partition, wherein the lower annular pressure header is linked to the distributing header of the core.

EFFECT: improved reactor performance.
