| 摘 要： | 在反应堆运行过程中，冷却剂中含有的氧化性气体杂质以及可能发生的进水事故和进气事故将导致石墨氧化，进而影响反应堆的正常运行和安全。文章主要对近期有关反应堆用石墨的氧化机理、氧化对石墨性能的影响、事故工况下的安全评估以及预防石墨氧化的措施等进行综述，并在此基础上指出，在辐照和氧化共同作用下的石墨材料性能变化是今后有关反应堆石墨研究的一个主要方面。

| Abstract: | In high-temperature gas-cooled reactor(HTGR),graphite is used as structural materials and moderator.During reactor operating,graphite oxidation has an effect on the safety and operation of reactor due to the impurities in coolant or water ingress and air ingress accidents which may take place.In the paper,the researches on the graphite oxidation in reactor were reviewed from four aspects,such as the mechanism of graphite oxidation,the influence of oxidation on graphite properties,the safety assessment in accident and the improvement the oxidation resistance of graphite.Some problems to be solved in future concerned in the graphite oxidition were put forward. |
