Construction method of steel containment reactor containment vessel

摘要

PURPOSE:To reduce the man power needed for constructing a reactor containment, shorten the constructing period and simplify the liner plating work and structuring work. CONSTITUTION:Inside of a structure body S consisting of inner steel plate 1, outer steel plate 2 and concrete charged in between them, a liner plate 4 is attached for constitution with a distance from the inner steel plate 1. Owing to the steel plate and concrete structure body S, the works for laying a high density reinforces such as iron and for assembling and disassembling the accompanying tentative equipment are unnecessary so that the man power is reduced and the work period is shortened. Also, owing to separating the liner plate 4 from the inner steel plate of the structure body S, the functions of the liner plate 4 and the structure body S are separated, each interface becomes easy and the works for the liner plate and the structure body are simplified.
