Comparative analysis of mechanical performance testing standards for graphite materials used in reactor internals
Graphite materials have important applications in the internal components of high temperature gas-cooled reactors,so selec-ting appropriate mechanical performance testing standards is crucial for ensuring the safe operation of nuclear power plants.This article selects common performance indicators such as tensile strength,flexural strength,compressive strength,and fracture toughness for the mechanical properties of ceramic stack internal component materials,and compares and analyzes domestic and foreign standards.By comparing the technical differences between standards,the impact of different standards on test results was analyzed,which could be helpful for providing reference and guidance for the mechanical performance testing and evaluation of graphite materials used in high-temperature gas-cooled reactor internals.
