Abstract:At present, the nuclear power plant (NPP) subjected to the commercial aircraft impact is the focus in the nuclear security field. According to the structure of a high temperature reactor NPP in China, five groups of aircraft fuselage model impact tests on scaled reinforced concrete (RC) walls were designed. The local failure characteristics of scaled RC walls with different reinforcement forms against the fuselage model impact were discussed. The results show that the head of the fuselage models appear different degrees of buckling deformation when they impact at different speeds,the scaled RC walls with different reinforcement forms are affected by the impact of the aircraft fuselage model. The local failure characteristics of the walls are different. When the wall is thicker and the impact force is small, the effect of stirrup in the wall is not obvious. However, when the impact force is large, the form of stirrup in the RC wall has an effect on the size and distribution of cracks. The U-shaped stirrup used in the test is superior to ordinary one in resistance impact. From the damage of the test wall, it can be preliminarily judged that the containment wall of the high temperature reactor NPP can basically meet the requirements of safety evaluation against small aircraft impact according to the guidelines. The relevant works and conclusions can provide data support for structural design, safety assessment of the small aircraft collision problems and verification and calibration of finite element models.
