In order to assess and enhance the capability of nuclear power plants to stand the deliberate crash of aircraft， the classical explicit nonlinear finite element dynamic program （LS-DYNA） was adopted， in which the impact load function in HAD101/04 was used on the containment of a nuclear reactor. The constitutive model of Johnson_Holmquist_Concrete and Plastic_Kinematic were used respectively to simulate the nonlinear performances of concrete and steel when aircraft crashing: large strain and high strain rate. The results show that the reactor containment can resist the impact of Boeing 707-320 simulated by HAD101/04.
