Effect of Neutron Irradiation on Structural Performance of Concrete Wall

Popis výsledku v původním jazyce

In this paper, the mechanical response of a concrete wall to long-term exposure to neutron irradiation is investigated. The radiation effect, represented by neutron flux, is modeled by volumetric swelling of concrete and corresponding degradation of the mechanical parameters of concrete. This effect is investigated using a three-dimensional finite element model of the wall, which has been created for this purpose. The potential effect of reinforcement is also included. Due to lack of relevant data, the degradation of the bond between steel reinforcement and concrete is represented by two limit cases of the perfect and no bond, while the realistic result will be between these two limit cases. As a result, displacement, isotropic damage and principal compressive and tensile stresses are obtained. According to the results of this analysis, the theoretical reinforced concrete wall is damaged to such an extent that its load-bearing capacity and shielding performance may be compromised.
