摘要：

In order to study the thermal stress failure behavior of the core matrix of the heat pipe reactor at high temperature, two high temperature test schemes were developed based on the simplified porous matrix structure and the design parameters of Megapower 5 MWt heat pipe reactor: normal condition and abnormal condition, in which the failure of a single heat pipe is considered under abnormal condition. The macroscopic test results show that there is no obvious deformation and failure of the matrix structure. Combined with numerical analysis method, the temperature distribution and stress-strain response of the matrix structure under two conditions are obtained, which further explains that the static strength failure and plastic collapse failure of the matrix structure will not occur under the test conditions. This study lays a foundation for defining the strength design criteria of the core matrix structure of the heat pipe reactor. © 2023 Yuan Zi Neng Chuban She. All rights reserved.
