Safety of Nuclear Power Plants against the Aircraft Attack

摘要

This paper presents the nonlinear dynamic analysis of the reinforced concrete building of nuclear power plant to the aircraft impact. The dynamic load is defined in time on the base of the simulation of the airplane impact considering real stiffness, masses, direction and velocity of the flight. The dynamic response is calculated in the system ANSYS using the transient nonlinear analysis solution method. The damage of the concrete wall is evaluated in accordance of the standard NDRC considering the spalling, scabbing and perforation effects. The simple and detailed calculation of the wall damage is compared.
