Nuclear power plant

The heat-transport-system building 16 of the nuclear power plant is in communication with one or more auxiliary buildings through a leak-tight joint across the seismic gap between the buildings. This joint is welding sealed leak-tight by a gap liner which includes flexible corner assemblies. Along the walls defining each corner of the heat-transport-system building and of an auxiliary building each flexible assembly includes a pair of members which may be described as box-like open at the bottom or of generally U-shaped transverse cross section. The outer arm of each U is joined to the metal which lines the associated wall; the inner arm is disconnected from the wall. At each corner there are two sets of these members, one set along the walls defining the corner of the heat-transport-system building and the other along the wall defining the corner of an auxiliary building. When the walls at the joint are displaced, each member of an assembly is deflected or deformed relieving the strain produced by the displacement so that the seal between the assembly and the walls remains leak-tight.
