STEEL PLATE CONCRETE STRUCTURE OF REACTOR CONTAINMENT VESSEL BUILDING, REACTOR CONTAINMENT VESSEL INTERNAL STRUCTURE, AND REACTOR CONTAINMENT VESSEL
PROBLEM TO BE SOLVED: To provide a reactor containment vessel building steel plate concrete structure, a reactor containment vessel internal structure, and a reactor containment vessel capable of relaxing reduction in strengths of an outer steel plate and a concrete while suppressing an out-of-plane deformation of the steel plate by a back pressure.SOLUTION: A steel plate concrete structure includes: a pair of steel plates that is an inner steel plate 21 and an outer steel plate 22 arranged opposed to each other at a gap therebetween, and exposed to a high-temperature environment; a pair of upper steel plates that is an upper bottom plate 25 and an upper top plate 26 arranged above the inner steel plate 21 and the outer steel plate 22, arranged vertically opposed to each other at a gap therebetween, and exposed to the high-temperature environment; a concrete 27 charged among the steel plates 21, 22, 25, and 26; a plurality of studs 28 arranged on surfaces of the respective steel plates 21, 22, 25, and 26 in contact with the concrete 27; and a steam exhaust pipe 30 in contact with a rear surface of at least one of the inner steel plate 21 and the upper bottom plate 25, and introducing steam to an outside of the concrete 27 via a pipe opening 26a provided in the upper top plate 26.
【課題】背圧による鋼板の面外変形を抑制した上で、外側鋼板及びコンクリートの強度低下を緩和することができる原子炉格納施設の鋼板コンクリート構造、原子炉格納容器内部構造物、及び原子炉格納容器を提供する。【解決手段】鋼板コンクリート構造は、互いに間隔をあけて対向して配置された高温環境に曝される内側鋼板２１と外側鋼板２２とからなる一対の鋼板と、内側鋼板２１及び外側鋼板２２の上側に配置され、互いに間隔をあけて上下に対向して配置された高温環境に曝される上側底板２５と上側天板２６とからなる一対の上側鋼板と、鋼板の間に充填されたコンクリート２７と、各鋼板のコンクリートと接する面に配置された複数のスタッド２８と、内側鋼板２１及び上側底板２５の少なくとも一方の裏面に接し、上側天板２６に設けられた管開口部２６ａを通じて蒸気をコンクリート外に導く蒸気排出管３０とを備える。【選択図】 図３
