Publication number: 20020131816Abstract: A locking ring holds a control rod drive housing tube of a nuclear power plant when a pressure chamber having a contact wall is pressurized. The contact wall faces the control rod drive housing tube presses against it when the pressure chamber is pressurized. The locking ring can lock a threaded nut after it has been screwed onto the control rod drive housing tube. In a method for securing a threaded nut of a control rod drive housing tube of a nuclear power plant in the vicinity of the threaded nut, a body is attached to the control rod drive housing tube, as a result of a contact surface of the body engaging the control rod drive housing tube. A contact surface of the pressure chamber is pressed onto the control rod drive housing tube when the pressure chamber is pressurized.Type: ApplicationFiled: October 29, 2001Publication date: September 19, 2002Inventors: Josef Forster, Georg Gebald, Alexander Hummeler, Hartmut Lelickens, Konrad Meier-Hynek

Patent number: 5970109Abstract: A method for disposing of a component located in a reactor pressure vessel of a nuclear reactor plant. The component is, in particular, a lower core structure of a pressurized water reactor plant. An upper part of a container provided for further transport is disposed above an opened and flooded reactor pressure vessel. The upper part is provided with a lower orifice. The component is raised through the orifice into the upper part of the container and is subsequently transported to an upwardly open lower part of the container. The upper part is assembled together with the lower part to form the container, so that the component is enclosed and shielded in the container.Type: GrantFiled: September 15, 1998Date of Patent: October 19, 1999Assignee: Siemens AktiengesellschaftInventors: Konrad Meier-Hynek, Gerd Reimer
