Device for the charge and discharge of nuclear reaction fuel assemblies

摘要

Two guide ramps for the transfer of fuel assemblies in sliding motion between the reactor core and an external storage container are surmounted by a lock-chamber in which two pivotally suspended rectilinear rail sections carried by a revolving unit form guide ramp extensions. Each rail section has a lever extension in cooperating relation with a rocking system for displaying the rail section in swinging motion from an inclined position in the line of extenson of one of the guide ramps to the vertical position and conversely.
