摘要

PURPOSE: An inner structure of a reactor building is provided to improve a wall safety by attaching an iron plate on an inner surface of a wall so as to form a shield surface. CONSTITUTION: An inner structure of a reactor building comprises a concrete wall(220), an iron plate frame(240), and steel-frame members. The iron plate frame(240) is stood on a fundamental part which forms an arrangement space(202) on which an equipment is disposed. The concrete wall(220) is stood with an area corresponding to an outer wall of the iron plate frame(240). The steel-frame members buried in the concrete wall is melt and attached on the iron plate frame(240). The iron plate frame(240) consists of division members, each of which comprises the steel-frame member.
