Coupled Numerical Analysis of Large Commercial Aero Plane Impact on Reactor Cavity of High Temperature Gas-cooled Reactor

  • 摘要: 本文建立了大型商用飞机撞击典型高温气冷堆核电站反应堆舱室的非线性有限元模型,计算中混凝土舱室直接采用工程用钢筋混凝土的损伤塑性本构模型,飞机结构采用Johnson-Cook本构模型。对飞机高速撞击高温气冷堆核电站反应堆舱室非线性撞击过程进行模拟计算,得出正面和侧面撞击条件下的撞击载荷曲线、撞击位移云图、反应堆舱室混凝土破坏情况等结果。评估表明,反应堆舱室结构在撞击条件下的整体损伤微小,可为保护内部关键设备提供重要的屏障功能。

     

    Abstract: A nonlinear finite element model of a large commercial aero plane impact on the reactor cavity of high temperature gas-cooled reactor was established in this paper. In the calculation, the concrete reactor cavity adopted the damage plastic constitutive model of engineering reinforced concrete and the aero plane adopted Johnson-Cook constitutive model. By simulating the nonlinear impact process of the aero plane impact on reactor cavity of high temperature gas-cooled reactor, the impact load curve, displacement contour and damage of concrete in the reactor cavity under frontal and lateral impact conditions were obtained. Assessment results show that the overall damage of reactor cavity structure under impact condition is small, so the cavity can provide an important barrier function for important equipment inside it.
