ABSTRACT:
In a nuclear power plant construction, a reinforced concrete containment vessel is installed on a foundation base mat and a reactor building is then installed around the reinforced concrete containment. The reactor building is provided with a plurality of concrete bodies, as floor slabs, projecting inwardly from an inner wall surface of the reactor building with spaces between the projected ends of the concrete bodies and an outer surface of the reinforced concrete containment vessel in vertically different levels in the reactor building. A precast concrete slab is arranged in each of the spaces between the concrete body of the reactor building and the outer surface of the reinforced concrete containment vessel with spaces therebetween. The precast concrete slab and the projected end of the concrete body of the reactor building and the precast concrete slab and the reinforced concrete containment vessel are joined with the joint assemblies. The joint assembly is a screw joint member or brackets or the combination thereof. The precast concrete slabs are joined to the projected concrete bodies of the reactor building and the reinforced concrete containment vessel successively from a lower level to an upper level of the location of the projected concrete bodies.
