Abstract
This study presents an experimental investigation on the oxidation behavior of nuclear graphite IG-110. A gas chromatography-based oxidation test platform was developed to monitor the oxidation processes of IG-110 graphite in different atmospheres. The oxidation tests focused on the presence of H2O and O2, with temperatures up to 750 °C and various partial pressures. The graphite consumption was analyzed, and a Boltzmann function was proposed to describe the relationship between graphite consumption and oxygen partial pressure. A graphite consumption prediction model was developed based on this function, which can be utilized to calculate the graphite consumption of CO/CO2 reaction products in High-Temperature Gas-cooled Reactors (HTGRs).
