Reinforced concrete containment structures in nuclear power plants are critical for protecting the population and environment from the uncontrolled release of radioactivity. These structures must withstand severe internal or external accidents, such as large fires, earthquakes, or aircraft impacts, that may occur during the plant’s lifetime.
This tutorial focuses on the numerical simulation of internal blast loading within a reinforced concrete (RC) containment vessel. The simulation uses the Coupled Eulerian-Lagrangian (CEL) method in Abaqus to analyze the dynamic response and damage mechanisms under varying scale distances of explosion.
Key parameters for modeling blast shock wave interactions are clearly defined. The study investigates the extent of concrete cracking, stress distribution in steel reinforcement and concrete after yielding, and overall structural deflection. The Eulerian volume fraction method is applied to model the explosion inside the containment.
Figures illustrating the simulation results are provided below.
