“…e load-time functions of various types of commercial and military aircrafts including A707-320, A320, Boeing 747, Boeing 767-400, and Phantom F4 were obtained using theoretical, numerical, or experimental methods [5][6][7][8]. Containment capacities to withstand these aircraft loadings were widely studied by researchers using load-time function methods [9][10][11][12]. e decoupled method has limitations in evaluating impact scenarios with complexity, such as striking with incident angles.…”

After the September 11 attack, the resistant capability of containments against aircraft impacts is required to be assessed for newly constructed nuclear power plants (NPPs). In this paper, the crash of a commercial airplane Boeing 767-200ER on the reinforced concrete containment building of an NPP is analyzed using the missile-target interaction method. Two plane models with the same total weight but different fuel distribution are analyzed. The force-time history obtained by FEA (finite element analysis) is compared with the one calculated by the Riera function. In the integral analysis, the mesh sensitivity of the reinforced concrete containment model is studied, and recommendations are provided on the modelling of containment. The impact phenomenon and damage on the containment are investigated through the validated model. The fuel distribution in the aircraft is found to have strong influence on the damage of the containment, which indicates that the load distribution in the transverse direction is critical in the analysis of aircraft impact. The classic load-time function analysis is unable to incorporate this factor and may not be adequate to provide satisfactory results. For this reason, the application of an integral analysis is advantageous in the safety assessment of aircraft impact.

“…Many works have been done to the dynamic response of the reinforced concrete containment under internal explosion [1] [2] [3]. Other works have carried out numerical simulations on the damage mode under aircraft crash [4] [5]. However, researches about the damage mode and pressure evolution of shield building under contact explosion were few in the past years.…”

Reinforced concrete (RC) shield building as the first external defense layer of AP1000 structure plays an important role in protection the population and environment when against the outer explosion. The strain rate effect of reinforced concrete was taken into consideration in the establishment of an AP1000 nuclear island structure-air-explosives fully coupled model by using the software AUTODYN. Object using damage mass as index, to infer the degree of damage. This paper studied the pressure evolution and damage mechanism. The analysis results provide valuable data on improving the anti-explosion capabilities in design based on the damage characteristics.

“…In Arros' works, the comparison of shock loading obtained from the Riera force history analysis with that from the missile-target interaction analysis was carried out, and sensitivity studies were also conducted. In the preliminary evaluation of aircraft impact on a nuclear containment of Frano and Forasassi (2012), the effects of different wall thicknesses and reinforced/prestressed concrete was carried out as a sensitive analysis.…”
