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。

Abstract

With the rapid development of nuclear industry, the disposal of highly radioactive waste becomes a major safety and environmental issue, and the deep geological disposal is a generally accepted solution. For the reduction and the anaerobic disposal repository of granite, the suitable canister material is the high-purity copper. This paper reviews the domestic and foreign researches of the electrochemical behavior of the copper corrosion in the high-level waste environment, including the geological environment of the repository, the mechanism and the process of the copper corrosion and the life prediction of the copper canister. This paper provides a theoretical basis for better assessment of the corrosion resistance of the copper and precise prediction of the disposal canister life in the repository environment.
