Abstract

Abstract

The mechanical response of HPR1000 reactor pressure vessel (RPV) and its main pipe under the hypothetical steam explosion load is studied. Through the establishment of the finite element model and the numerical analysis according to the transient structure analysis method, the deformation, stress and strain results of RPV and the main pipeline are obtained. The results show that the failure loads of RPV at 600℃, 800℃ and 1000℃ are 1/20, 1/50 and 1/100 design loads respectively; The maximum equivalent stress/strain is located near the nozzle; The stress in most areas of the main pipe does not exceed the yield stress of the pipe. This study can provide technical support for structural integrity analysis of RPV under extreme load.
