如果核安全壳结构在战争或恐怖袭击中完全或部分失效，可能会导致严重的辐射泄漏。针对幻影F4军用喷气机可能发生的坠毁事故，对沸水堆Mark III型安全壳进行了安全性分析。采用有限元软件ABAQUS/Explicit进行了数值模拟。飞机的正常撞击被认为是在安全壳底部附近。通过反应时间响应曲线提供了冲击力的加载。混凝土损伤塑性模型已被纳入到模拟混凝土在高应变率下的行为，而韧性金属的Johnson-Cook弹粘模型已被用于钢筋。评价了接触面积的影响。据报告，接触面积为28 m2时，安全壳厂房的最大变形为64.77 mm，而接触面积为10 m2时，观察到的最大变形约为135 mm。在冲击区域已经注意到非常高的局部变形。安全壳内表面的拉伸损伤比加载表面的压缩损伤更显著。此外，在结构中没有观察到明显的整体损伤。在更高的速度下，Phantom F4可能会破坏结构。
Complete or partial failure of nuclear containment structures, if targeted during war or terrorist attacks, may cause heavy radiation leakage. Safety analysis of BWR Mark III type containment has been performed in the present study against possible crash of military jet Phantom F4. Numerical simulations have been carried out using finite element code ABAQUS/Explicit. A normal hit of the aircraft has been considered near the base of containment. Loading of the impact force has been provided through reaction time response curve. Concrete Damage Plasticity model have been incorporated to simulate the behaviour of concrete at high strain rate, while Johnson-Cook elasto-visco model of ductile metals have been used for steel reinforcement. Effect of contact area has been evaluated. Maximum deformation in the containment building has reported as 64.77 mm for 28 m2contact area, while for contact area of 10 m2it has been observed about 135 mm. Very high local deformations has been noticed in the impact region. Tension damage at the inner face of the containment are more significant than the compression damage at the loading face. Moreover, no significant global damage has been observed in structure. At higher velocities Phantom F4 may perforate the structure.
