Abstract
A set of cylindrical shells is interposed between the main vessel wall of an integrated sodium-cooled fast reactor and the primary core containment vessel so as to form a siphon having two downwardly directed branches. One branch opens into the intervessel zone which is separated from the primary vessel by a shell. The other branch which is nearest the main vessel wall is supplied with part of the cold sodium which has been withdrawn from the intervessel zone by means of pumps and reinjected into the bottom of the reactor core.
