Abstract

In the survey stage of nuclear power plant site, it is necessary to consider the impact on nuclear power station brought by the aircraft. The most serious consequence is the fuel leak. The fuel combustion process is divided into two stages of deflagration and pool fire. This paper is mainly focus on the simulation of deflagration and pool fire effect after the impact caused by aircraft impacting the architectural workshop, based on general computational fluid dynamics software CFX, using the method of numerical to analyze the duration of the deflagration and pool fire stage, transient temperature, pressure, changes in fuel concentration, and the effects of different impact height on deflagration and pool fire combustion process. The results show that, during deflagration and pool fire combustion period, the influence of temperature on the structural strength of buildings is low, so is the influence of pressure.
