Title:
CONCRETE STRUCTURE
Document Type and Number:
Japanese Patent JP2021195720
Kind Code:
A
Abstract:
To provide a heat-resistant concrete structure capable of maintaining the soundness of a reactor containment vessel even if an atmospheric temperature of the reactor containment vessel becomes high over a long period of time due to a core meltdown accident caused by the loss of full AC power supply.SOLUTION: A concrete structure according to an embodiment comprises: a tie bar 11 for connecting surface steel plates 7, 8 of an SC structure 6; a steel plate frame 9 composed of the two surface steel plates 7, 8; a stud 12 fixed to a part of inner surfaces of the surface steel plates 7, 8; a heat-resistant material 14 having heat insulation properties laid on at least a part of the inner surface of at least one of the surface steel plates 7, 8; and concrete 10 placed using the steel plate frame 9 as a form. The heat-resistant material 14 having heat insulation properties is fixed between the steel plate frame 9 and the concrete 10.SELECTED DRAWING: Figure 2
