Abstract

The invention is directed to a docking arrangement for docking a container o a lock having a first side facing into a first chamber wherein contamination is present and a second side facing into a second chamber free of contamination. A lock wall defines the lock opening and a lock cover is adapted to close the lock opening. The container is provided for receiving radioactive materials and has a container vessel which is closed by a container cover. The docking arrangement includes an intermediate cover releasably connectable to the container cover. A holder is provided for engaging the intermediate cover to move the intermediate cover together with the container cover for opening and closing the lock opening. The intermediate cover is disposed between the lock cover and the container cover. An annular member is located on the second side and form-fittingly engages the lock wall. The intermediate cover is subdivided into a first portion covering the container cover and a second portion covering the annular member with the second portion extending to the lock wall. A first set of seals seals the docking arrangement with respect to parts which should not be subjected to contamination…
