The Response of Outer Containment of Nuclear Reactor in Aircraft Crash

摘要

The impact of aircraft crash on concrete outer containmentof nuclear reactor has been aimed to know. After 9/11terroristattacksand aircraftcrasheswith Twin Towers in theUnited States, the issue of nuclear safety and sustainabilityagainst plane crashes get more concerned. Destruction ordamages of a nuclear power plant can lead to large-scalereleaseof radioactive material and consequently itcan bringabout human and environmental disasters. In this article,the behaviour and response of concrete outer containmentof nuclear reactor during a crash or moment loading isanalysed through modelling Boeing-707 and Boeing-747aircraft and also Phantom-F4 military aircraft. Dynamicload the aircraft is stimulated by using Riera’s time-forcecurve. During the crash impact load and explosion occursimultaneously, and then it is applied to critical locationwhere dome caps are connected to cylindrical walls ofreinforced concrete nuclear reactor. Assessment of thisclash is done by stimulation of concrete outer containmentof nuclear reactor ABAQUS software. The behaviour of twocontainment areas of the nuclear reactor, i.e. the cylindricalbody and the junction of the cylindrical dome cap, areevaluated in this paper. The results show a similarbehaviour of reinforced concrete reactor chamber when theaircraft crashes with the dome cap and cylindrical wall thanotherpartsof thereactorchamber.
