Core container for a fluid-cooled nuclear reactor

摘要

The invention relates to a core container (2) for a fluid-cooled nuclear reactor having a core shroud (3) which is used for guiding the coolant, encloses the fuel elements (4) and consists of flat, vertical, rectangular core shrouding plates (19 to 23) which are screwed to one another. The individual core shrouding plates are provided with grooves (25 to 36) exclusively in the region of their edge facing the axis of symmetry (14), in order to reduce the screw stress in the stepped region (15 to 17) of the core shroud. <IMAGE>
