摘　　要：随着核工业的飞速发展,高放射性废物的处置成为重大安全和环保问题,而深地质处置是普遍接受的方案。在处置库花岗岩环境及无氧还原条件下,更适合的处置罐材料为高纯铜。本文从处置库的地质环境、铜处置罐的腐蚀、铜处置罐的寿命预测等方面,综述处置库环境下纯铜的腐蚀电化学行为的研究进展,以更好地评估纯铜在处置库环境下的耐蚀性能及预测处置罐的寿命。With the rapid development of nuclear industry, the disposal of highly radioactive waste becomes a major safety andenvironmental issue, and the deep geological disposal is a generally accepted solution. For the reduction and the anaerobic disposalrepository of granite, the suitable canister material is the high-purity copper. This paper reviews the domestic and foreign researches of theelectrochemical behavior of the copper corrosion in the high- level waste environment, including the geological environment of therepository, the mechanism and the process of the copper corrosion and the life prediction of the copper canister. This paper provides atheoretical basis for better assessment of the corrosion resistance of the copper and precise prediction of the disposal canister life in therepository environment.
