PROBLEM TO BE SOLVED: To materialize a nuclear reactor containment vessel made of both-side steel plate/concrete by employing a structure in which tensile force transmitted to concrete is reduced to within a structural design allowance even if a temperature difference increases between an inside steel plate and the concrete, thereby achieving work period shortening and cost reduction for the containment vessel. SOLUTION: In this nuclear reactor containment vessel 1 made of both-side steel plate/concrete, the concrete 12 is placed between steel plates 10 and 11 disposed inside and outside, and shear connectors 13 are attached to surfaces 10a and 11a of the steel plates 10 and 11 on the concrete 12 side. A carbon fiber layer 14 is provided on the surface 10a of the inside steel plate 10 on the concrete 12 side. COPYRIGHT: (C)2007,JPO&INPIT
