Abstract

Improvements introduced into a support structure for a fast-neutron nuclear reactor core, which includes a horizontal sleeper in which the feet of the fuel assemblies that form the core are inserted, this sleeper constituting a high-pressure collector for a liquid metal cooling system of these assemblies that circulates from the bottom to the top through the core, to collect in an internal tank, a perforated metal frame that supports the sleeper and is joined by its periphery to the internal surface of a main tank that surrounds the internal tank., and a core ashtray mounted under the sleeper and which includes a cylindrical side ferrule and a lower bottom that delimits an area containing a core collection plate in case of accidental fusion, characterized in that the ashtray ferrule includes at least a metallic separation wall arranged above the plate and dividing the space delimited by the ferrule into Two areas, one of which, between the wall and the sleeper, permanently collects liquid metal leaks from the sleeper at the foot of the assemblies, these leaks being channeled under the underside of the frame towards the surface of the main tank, and the other of which, between the wall and the bottom of the ash field, communicates with the outside of the ferrule by chimneys formed through the frame with the area delimited between the main tank and the internal tank.
