The oxidation of the bottom reflector graphite in HTR-10 of Tsinghua University during air ingress accident were studied numerically based on a theoretical calculation model, which considered the changes of chemical reaction rate and mass transfer speed with weight loss in oxidation process. The results showed that oxidation degree of the bottom reflector increased nearly exponentially with temperature; the oxidation corrosion quantity increased significantly over time accumulation; weight loss calculated by this model is larger than previous models, so reactor graphite structure design should be paid more attention.
