“…e aircraft is assumed to strike the containment normally at a height of 40 m, which is approximately half of the total height. is condition is considered the most destructive case as reported by Sadique et al [11] and Zhang et al [13]. e initial velocity of the aircraft is assumed to be 150 m/s, which is used by Jeon et al [30] for structures with relatively low altitude.…”

“…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.…”

“…e results indicated that the outer containment wall was likely to experience local damage, although the overall stability of the containment structure was warranted. Sadique et al [11] showed that global failure occurred in the Indian BWR Mark-III-type nuclear power plant when it was hit by Boeing 747-400 and Boeing 767-400 aircrafts, while only local damage was observed when it was hit by A320 and A707-320. ai and Kim [7] analyzed the influence of aircraft impact on the auxiliary building as well as the equipment in the building and found that the global and local structural safety of the building was ensured, but the safety of the equipment was not warranted because of the excessive vibration of the building.…”

“…However, in the missile-target interaction analysis in the literature, only 4 elements through wall thickness were used in the containment model because of the large computational complexity and consumption for an integral analysis. A mesh convergence study was carried out by Sadique et al [11] for a load-time function analysis. However, studies on mesh sensitivity have not been reported in missile-target analysis, and the validity of coarse models with 4 elements through wall thickness still remains in doubt.…”

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.

“…This device is built in laboratory-sizes to produce isotopes of radioactive materials as well as radiation-drugs for medical purposes and also in industrial-sizes to generate electricity (Sadique , 2013). Worldwide, while producing energy using fossil fuels is getting more expensive, nuclear electricity producing in the nuclear power plants using nuclear f ission reaction is an excellent source for electricity generation.…”

Since the 9/11 attacks, whether nuclear power plants (NPPs) can withstand the malicious impact of large commercial aircraft has become a question that must be considered in the design phase. Refined model and fine-scale element reflect more accurately the failure procedure and behaviour. However, due to the exceedingly complex structure of NPP, the traditional meshing method requires a substantial number of geometric operations involving point, line, area, and volume, leading to a tedious modelling process and very high computational costs, as well as making it difficult to modify and optimize the model. This paper combines the scaled boundary finite element method with the octree technique to refine nuclear engineering damage evolution analysis and establish a refined numerical model of the Generation III + NPP, considering the detailed equipment hatch, air intake, and internal steel containment vessel structures. Subsequently, the refined damage evolution analysis of a large commercial aircraft crashing into an NPP was developed. The mesh size sensitivity, impact region shape comparison, and the influence of different impact heights were discussed. The results indicate that the cross-scale refined meshing and analysis method provides a high-quality discrete grid with fewer elements. Furthermore, this method is highly flexible, more accurately simulating the damage evolution and gradual destruction process. We recommend future structural optimization for the air intake and conducting detailed analyses at this location. The cross-scale analysis method presented in this paper enables a rapid, refined simulation of a malicious impact by a large commercial aircraft. Additionally, it provides technical support for future studies of the responses of NPPs' internal structures, systems, and equipment under extreme earthquake and other disaster conditions.
