Abstract
The annular space (19) delimited by the main vessel (3) and an internal shell (16) is in communication with the zone (15) of the reactor vessel, in which the cold primary liquid is located. The annular space (20) delimited by the shell (16) and by an internal shell (17) is in communication with the lower part of the core (7) via tubes (31). Thus, the cold primary liquid is injected into the space (20), where it circulates from bottom to top, and flows into the space (19), where it circulates from top to bottom while at the same time cooling the main vessel (3). The invention applies, in particular, to fast fission nuclear reactors cooled by liquid sodium.
