Investigations of large commercial aircraft impact effect on nuclear power plant (NPP) buildings havebeen drawing extensive attentions, particularly after the 9/11 event, and this paper aims to numericallyassess the damage and vibrations of NPP buildings subjected to aircrafts crash. In Part I of present paper,two shots of reduce-scaled model test of aircraft impact on NPP were conducted based on the largerocket sled loading test platform. In the present part, the numerical simulations of both scaled andprototype aircraft impact on NPP buildings are further performed by adopting the commercial programLS-DYNA. Firstly, the refined finite element (FE) models of both scaled aircraft and NPP models in Part Iare established, and the model impact test is numerically simulated. The validities of the adopted numericalalgorithm, constitutive model and the corresponding parameters are verified based on theexperimental NPP model damages and accelerations. Then, the refined simulations of prototype A380aircraft impact on a hypothetical NPP building are further carried out. It indicates that the NPP buildingcan totally withstand the impact of A380 at a velocity of 150 m/s, while the accompanied intensive vibrationsmay still lead to different levels of damage on the nuclear related equipment. Referring to theguideline NEI07-13, a maximum acceleration contour is plotted and the shock damage propagationdistances under aircraft impact are assessed, which indicates that the nuclear equipment located within11.5 m from the impact point may endure malfunction. Finally, by respectively considering the rigid anddeformable impacts mainly induced by aircraft engine and fuselage, an improved Riera function isproposed to predict the impact force of aircraft A380
