Abstract
A cylindrical steel vessel for nuclear reactors having a cover and a bottom wall is provided with a protective device against axial rupture of the vessel that includes tensioning members which connect a second cover and a second bottom or base one to the other. Also included are a plurality of rings, respectively formed of a sheet metal wrapping, wound around the cylindrical part of the vessel. Between the sheet metal wrapping and the vessel there is a filler of removable light concrete for thermal insulation and shock absorption in the event of a rupture of the vessel. Also disclosed is a method of manufacturing the protective device.
Claims3
Protective device against rupture of a large cylindrical vessel having a first cover and a first bottom wall and, superimposed respectively thereon, a second cover and a second bottom wall, and further having tensioning members mutually connecting the second cover and the second bottom wall, comprising mutually superimposed rings formed of respective sheet-metal wrappings, each having a plurality of turns wound about the cylindrical part of the vessel between the second cover and second bottom wall thereof, said sheet-metal wrappings have an inner diameter greater than the outer diameter of the large cylindrical vessel, the rupture of which is being protected against, the space between said sheet-metal wrappings and the large cylindrical vessel being filled with light concrete segments.
