Abstract
A part of the cold liquid metal which is injected at the base of the reactor core is circulated along the bottom portion of the main reactor vessel and guided by a shell which is concentric with the vessel. A mass of inert gas is trapped within a leak-tight annular chamber above the liquid metal. During reactor operation, the gas pressure is adjusted in order to maintain the gas/liquid metal interface at a substantially constant level and to obtain along the vessel a temperature distribution which ensures limited amplitude of stress variation.
