Title:
NUCLEAR REACTOR BUILDING
Document Type and Number:
Japanese Patent JP2017156109
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To cause no problem because not only stresses and high frequency vibrations generated are reduced when flying objects crash against a nuclear reactor building but also because of vibrations generated at the time of earthquakes and collusion of the flying objects.SOLUTION: In order to solve the above described problem, a nuclear reactor building according to the present invention stores a nuclear reactor containment in which a nuclear reactor pressure vessel is stored and made of a roof, an outer wall, an inner wall, and a floor. The nuclear reactor building includes: a protection wall independently fixed to each of the outer wall and the roof of the nuclear reactor building; a buffer member independently arranged among the protective wall, the outer wall, and the roof; respectively. The fixing device is released from the fixing to the outer wall or the roof of the protective wall when the flying object collides against the fixing device.SELECTED DRAWING: Figure 1
