特徴とする原子炉格納容器の配管貫通部構造。 A pipe penetrating a steel container wall and a concrete shielding wall installed parallel to the steel container wall at intervals from its surface, and airtightly fixed to the steel container wall, concrete shielding wall, and piping, respectively. The outer cladding tube is provided in an externally inserted state, and the outer cladding tube has a ring-shaped ring for leakage testing on its inner periphery so as to surround the inside of both the fixed parts with the steel container wall and the concrete shielding wall. An internal pipe forming an airtight chamber is fixed airtightly, and is divided into a plurality of parts between each fixed part to both ends of the internal pipe, the steel container wall, and the concrete shielding wall. A piping penetration structure for a reactor containment vessel characterized by an expansion joint airtightly connected therebetween.
