核电站在大型商用客机撞击下损伤破坏研究进展.

After the September 11, 2001 event, a series of regulations was issued by USA Nuclear Regulatory Commission, Nuclear Energy Institute, Department of Energy as well as National Nuclear Safety Administration of China. It is specified that the newly built nuclear power plant ( NPP) should be designed to resist the accidental impact and terrorist attack by large commercial aircraft. In the present paper, from the three aspects, e. g. , integral responses of NPP under aircraft fuselage impact, local responses of NPP under aircraft engine impact, structural vibrations of nuclear island buildings, the state of the art in the theoretical model, prototype and reduced scale modelling test, numerical simulations for the damage and failure of nuclear island infrastructures under large commercial aircraft impact were reviewed comprehensively. Furthermore, our recent work in the above areas were briefly introduced, inducing the fine finite element models of four typical aircrafts ( F4 fighter, Airbus A320, A380, MA600) , four NPP infrastructures ( prestressed RC NPP containment, RC NPP containment and auxiliary buildings, steel concrete NPP containment and auxiliary buildings，RC large-scale cooling tower)，as well as the reproductions of the whole collision processes based on numerical simulations. Besides, the reduced scale engine impact test on normal RC and ultra-high performance concrete target plates, the corresponding numerical simulations, as well as the calculation approach for the terminal ballistic parameters of engine were introduced. Finally, the shortages in the existing work such as calculation of impact force, intergral response, local damage, vibration effect and multi-hazard impact, and the future research recommendations were pointed out.
