Analysis of Dynamical Response of Nuclear Power Plant Concrete Containment under Contact Blast Load

Nuclear power plant may be the target of the precision-guided bomb unit in the modern war and the attack of terrorists. Nuclear power plant containment shell is a large-volume pre-stressed reinforced concrete silo-shell structure to prevent radioactivity, and is the most important protected object in special condition. Based on the structure of nuclear power plant containment, this paper uses liquid-solid coupling arithmetic to analyze the concrete containment dynamical response under contact blast load. Detailed analysis reveals the law of structure damage and stress distribution of the containment shell in contact blast. These numerical values provide important technical parameters for the decision of safety measures for NPP in war.
