| Abstract: | For the disastrous results of the released reactive fuel after the damage to the nuclear power plants（NPP）,the NPP containment（NPPC） is one of the most potential targets in both military strikes and terroristic activities.In this paper,the state of arts of key scientific problems,which are related to the impact and blast effects of the projectiles and airplanes striking on the NPPC are concluded.It is pointed out that the main focuses in the research of the protective performance of NPPC are： Firstly, the damage effect of double layered reinforced concrete shields and steel liner composite target under the high-speed penetration（perforation） and blast effects of projectile;Secondly,the fine numerical simulations of the dynamic responses of NPPC under the impact of large commercial airplanes,with the consideration of the double-layered structure,concrete model,mass and rigidity distribution of the airplane,impact velocity and location,loading area and etc.;Thirdly,the damage mechanism of reinforced concrete under coupling effects of impact blast and fire. |
