商用飞机对核岛基础设施的冲击效应研究一直受到广泛关注，本文旨在对典型商用飞机撞击下的第三代核电站建筑进行安全评估。目前，第二部分基于已验证的空客A320和A380飞机以及本文第一部分的核电站安全壳和辅助建筑的有限元模型，采用弹靶耦合耦合方法，采用LS-DYNA有限元代码对整个碰撞过程进行数值再现。对核电站安全壳（钢瓶、进气口、圆锥形顶板和PCS水箱）四个冲击部位和辅助建筑（乏燃料池室外墙和顶板）两个冲击部位的冲击损伤进行了评价。在此基础上，考虑核电站围护结构和筏形基础的内部结构，对两个冲击位置（筒体中间高度、辅助建筑主控室）进行了结构振动分析。这表明，在讨论的场景下，NPP结构可以承受两架飞机的冲击，而在冲击诱发振动下，较高楼层的内部设备的功能会受到一定影响，A380飞机比A320飞机造成更严重的结构损伤和振动。本研究可为民用飞机冲击下核电厂结构及内部设备的安全性评估提供有益的参考。
Investigations of the commercial aircraft impact effect on nuclear island infrastructures have been drawing extensive attention, and this paper aims to perform the safety assessment of Generation III nuclear power plant (NPP) buildings subjected to typical commercial aircrafts crash. At present Part II, based on the verified finite element (FE) models of aircrafts Airbus A320 and A380, as well as the NPP containment and auxiliary buildings in Part I of this paper, the whole collision process is reproduced numerically by adopting the coupled missile-target interaction approach with the finite element code LS-DYNA. The impact induced damage of NPP plant under four impact locations of containment (cylinder, air intake, conical roof and PCS water tank) and two impact locations of auxiliary buildings (exterior wall and roof of spent fuel pool room) are evaluated. Furthermore, by considering the inner structures in the containment and raft foundation of NPP, the structural vibration analyses are conducted under two impact locations (middle height of cylinder, main control room in the auxiliary buildings). It indicates that, within the discussed scenarios, NPP structures can withstand the impact of both two aircrafts, while the functionality of internal equipment on higher floors will be affected to some extent under impact induced vibrations, and A380 aircraft will cause more serious structural damage and vibrations than A320 aircraft. The present work can provide helpful references to assess the safety of the structures and inner equipment of NPP plant under commercial aircraft impact.
