Abstract

Abstract

Among all kinds of accident hazard factors around the nuclear power plant, the consequence of explosion shock wave overpressure is more serious. In the nuclear safety guidelines, the TNT equivalent method is used to evaluate the overpressure of explosion shock wave, and there is no calculation model related to gas cloud explosion. By analyzing the Trinitrotoluene (TNT) equivalent method, the Netherlands Organization for Applied Scientific Research (TNO) model and the Baker-Strehlow-Tang (BST) model, this paper evaluates the applicability of the three models. The results show that the calculation results of TNT equivalent method are conservative, while the BST model can accurately evaluate the impact range of explosion shock wave overpressure of natural gas pipelines around the nuclear power plant. According to the calculation results of the BST model, the shock wave overpressure caused by the accidental explosion of three typical pipelines has little effect on the nuclear power plant.
