Abstract
A device for coupling a pressure vessel closure cap to an upper structure for supporting the reactor internals comprises a plurality of locking-keys which are guided in translational motion within radially disposed housings and can be moved into outwardly projecting positions by externally-controlled actuating means in order to engage in opposite recesses formed in the internal wall of the closure cap.
