大型客机撞击下核电站屏蔽及附属厂房的损伤破坏与振动响应研究

Aiming to deal with the accidental and terroristic aircraft impact, the National Nuclear Security Administration has issued the regulations of HAF102-2016 “Safety Design Regulations of Nuclear Power Plant”, it is specified that the nuclear power plant should be designed to resist the large commercial aircraft impact. However, the related domestic researches are still limited. The damage and vibration of AP1000 nuclear power plant (NPP) containment, auxiliary buildings and inner equipment under A380 large commercial aircraft impact are addressed in this project. The impact tests on the reduce-scaled model of NPP containment and auxiliary buildings, the shock & vibration test of the prototype equipment, the theoretical analyses of the aircraft impact force and engine penetration/perforation, as well as the fine numerical simulations of the whole collision process will be conducted. It is expected that, the theoretical models of the aircraft impact force and engine low-velocity impact on the steel plate/concrete composite structures will be established. Besides, the analyses and evaluation approaches for the damage and vibration of NPP containment, auxiliary buildings and inner equipment under aircraft impact will be proposed. Finally, the “Design guidelines for NPP against aircraft impact” will be published. The present researches are expected to provide the theoretical basis and technical support for the evaluation and design of the existing and newly-built NPPs under aircraft impact. It has important theoretical and practical application meanings in enhancing the survivability of the related NPP facilities and equipment under aircraft impact, and guaranteeing the safe operation of NPP and healthy development of nuclear engineering.

为了应对事故型和恐怖性飞机撞击，国家核安全局发布了HAF102-2016《核动力厂设计安全规定》，明确规定我国核电站建设必须考虑商用飞机的恶意撞击，然而国内在该领域的研究还处于起步阶段。本项目拟围绕A380大型商用客机撞击下AP1000核电站屏蔽和附属厂房的损伤破坏及其内部结构和设备的振动响应，开展厂房缩比模型冲击和原型设备冲击振动试验、飞机撞击力和引擎侵彻贯穿理论、以及飞机撞击全过程精细化数值模拟研究。建立飞机撞击力和引擎低速冲击钢板/混凝土复合结构的理论模型，提出飞机撞击作用下厂房结构损伤破坏、厂房结构及其内部设备振动响应的分析与评估方法，形成《核岛厂房抗飞机撞击设计指南》。预期研究成果可为现有和新建核电站抗飞机撞击评估与设计提供理论基础和技术支撑，对于提升重要核岛设施设备在大型客机撞击作用下的抗毁生存能力，保障核电站安全运行与核能事业健康发展具有重要的理论研究价值和工程应用前景。
