摘要
高温气冷堆均选用石墨材料作为结构材料和慢化剂。在反应堆的运行过程中,由于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,会发生石墨材料的氧化,进而影响反应堆的正常运行和安全。本文主要对近期反应堆用石墨材料的氧化研究进行综合评述,并在此基础上,指出今后需要进一步研究的内容。
In high temperature gas-cooled reactor （HTGR）, graphite is used as structural materials and moderator. During reactor operating, graphite oxidation which influences the safety and operation of reactor occurs due to the impurities in coolant or water ingress accident and air ingress accident which may be take place. In this paper, the oxidation process of graphite was introduced firstly, and then the factors which influence the graphite oxidation were analyzed and discussed.Some new questions for further studing were given.
