    • PROBLEM TO BE SOLVED: To provide a reactor-containment vessel container that reduces work regarding RCCV (reinforced concrete reactor containment vessel) construction at a contruction site, to increase the efficiency of building work for improving safety, and greatly reduce the building period, and its building method. SOLUTION: A reactor-containment vessel 2 made of reinforced concrete is accommodated into a reactor building. A cylindrical part liner 10 for composing the reactor-containment vessel 2 and bar arrangements 11 and 90 inside an RCCV provided outside the liner 10 are assembled on the ground in advance for suspending and installing in a construction site. For a diaphragm floor 8 for dividing the reactor-containment vessels 2 and 10 into an upper dry well 28 and a lower pressure suppression room 25 and a top slab which is provided for covering the top part of the reactor-containment vessel 2, both of the diaphragm floor liner module and the top slab module that compose the diaphragm 8 and the top slab are assembled on the ground in advance as a one-piece structure for suspending and installing in a setting position at the construction site.
