Abstract: Device for transporting radioactive material having a lifting mechanism displaceable along a travel path, includes an operator's cab shielded against radiation and displaceable with the lifting mechanism along the travel path, a control console for actuating the lifting mechanism, the control console being disposed in and displaceable with the cab, filter means through which the cab is ventilated with filtered air, and means for testing the ventilating air for freedom thereof from radiation.

Abstract: In a device for coupling pipelines in a pressure vessel of a nuclear reactor having a first piping section sealingly extending through the pressure vessel-housing wall and fastened thereto, and a second piping section sealingly connected to the first piping section, as well as a core container fastened within the pressure vessel, the core container having a cover, and steam separators forming, together with the core-container cover, a structural unit, the second piping section being also included with the core-container cover and with the steam separators fastened to the cover in the structural unit and, when the pressure vessel is opened, the second piping section together with the core-container cover being liftable out of the pressure vessel and being reinsertable into the pressure vessel, the first and the second piping sections being in mutual contact at coaxial sealing surface portion formed thereon at the sealed connecting location thereof, said sealing surface portions being placeable into a nominal l

Abstract: For coupling pipelines in a nuclear reactor pressure vessel with a core flood line formed of a first line section extending sealingly through a housing wall of the reactor pressure vessel and secured thereto, and a second line section disposed in the interior of the pressure vessel and couplable sealingly to the first line section, the second line section extending through a cover of a core container and terminating in the core container, a device includes means for forming the second line section and the core container cover into a structural unit so that the second line section together with the core container cover is liftable out of and insertable into the pressure vessel upon opening the latter for selectively inspecting, servicing and both inspecting and servicing the same, the first and second line sections having a mutual coupling location, means defining coaxial sealing surfaces disposed at the mutual coupling location for holding the first and second line sections in mutual engagement, the coaxial s
