The invention is directed to an arrangement for transferring irradiated f rods from a trough-shaped receptacle into a canister intended for terminal storage. The canister is docked at a pass-through opening formed in a partition wall of a nuclear facility. The arrangement includes a trough-shaped insert which is movable out of the terminal storage canister while empty and through the pass-through opening into the trough-shaped receptacle whereat it is filled with the irradiated fuel rods and then returned back through the opening and into the terminal storage canister. In this way, and with little effort, a transfer of fuel rods is achieved without components disposed between the receptacle and canister becoming contaminated by radioactive particles.

The invention is directed to a lock system for permitting objects to be ped from a contaminated chamber into a container which is disposed in a contamination-free chamber and docked to the lock system. The lock system of the invention includes a displaceable insert mounted on a partition wall separating the chambers. The insert is in the form of a round disc rotatable about its center point. The disc includes lock openings having different cross sections which are arranged on a circle concentric to the center of the disc. The lock system of the invention permits objects of different shape and size to be passed through the lock along only one removal path.
