ABSTRACT:
In a sodium-cooled fast reactor comprising a reactor tank and diagrid, a core support grid carried by the reactor diagrid and a number of pipes each supplying the support grid with liquid sodium coolant through a bellows seal, the reactor diagrid is constituted by a rigid annular structure having a flat annular bearing face resting on an annular bearing face of the core support grid. High flexural rigidity of the support grid is provided by strengthening ribs, by welded through-passage columns for the fuel elements and by a raised peripheral framework mounted on the support grid for carrying the shield system.
