REACTOR CONTAINMENT FACILITY

摘要

PROBLEM TO BE SOLVED: To provide a reactor containment facility in which a gap between a first shear lag member and a second shear lag member can be adjusted accurately and the first shear lag member and the second shear lag member can be installed easily.SOLUTION: A reinforced concrete reactor container 1 included in a reactor containment facility includes a top slab 2, an upper cover and a cylindrical reactor container sidewall. The top slab 2 includes liners 3A, 3B communicating to an upper end portion of the reactor container sidewall and covering a bottom face of a reinforced concrete part 2A and a side face at the side of an opening part 19. A male shear lag 16 extending upwardly is installed in an upper end of a reactor shield wall 11 surrounding a reactor pressure vessel. The male shear lag 16 is inserted into a groove part formed at a distal end portion of a female shear lag 17 mounted to a side face of the liner 3B. A gap formed between a side face of the male shear lag 16 and a bottom face of the groove part is set to a predetermined dimension in a radial direction of the reactor pressure vessel.
