BLOCKING ARRANGEMENT FOR MECHANISM FOR HANDLING FUEL ASSEMBLIES IN NUCLEAR REACTORS

Fuel assemblies for nuclear reactors are positioned in a receiving member, from which they, as well as a control rod, can be lifted by a gripping device having two legs pivoted to each other. A stop arrangement is provided which prevents the gripping device from lowering the fuel assembly all the way into the receiving member unless it is properly oriented with respect thereto.
