ABSTRACT:
A pressure vessel, especially as a containment for a nuclear reactor core, comprises a stack of horizontal cast-metal members which define horizontal joints or seams between them, the stack being held together under pre-stress by a multiplicity of tension elements, e.g. cables or rods. The stack is provided with a liner welded together from steel sections and having, in the region of the seams, a reduced thickness as well as a lower yieldability or tensile strength than the yieldability or tensile strength of the liner sections elsewhere. As a result, rupture of the liner is ensured in the region of the seams which constitute preferred pressure release cracks in the event of an explosion or excessive development of pressure within the vessel.
