Abstract

Abstract

In order to obtain the creep behavior of reactor pressure vessel (RPV) materials at high temperature and ensure the integrity of RPV under severe accident conditions, the high temperature creep properties of 16MND5 steel for domestic RPV were tested, and the creep property of the material at 600~900℃ was obtained. Based on the basic creep constitutive model of strain strengthening and the creep damage model based on ductile depletion theory, a creep damage constitutive model suitable for 16MND5 material is established, and the creep damage model parameters are given. Results show that the finite element simulation data of the creep damage constitutive model proposed in this paper are in good agreement with the experimental data, which verifies the correctness of the creep damage model. This method can be used for the creep damage analysis of RPV under serious accidents, and provide support for the integrity analysis of RPV.
