钚在低碳钢包装容器腐蚀产物上的吸附行为研究进展

研究低碳钢材质容器腐蚀机理及其腐蚀产物对钚的吸附行为对评价放射性废物处置场地安全性具有重要意义。通过研究低碳钢包装容器在放射性废物处置库中的腐蚀行为以及腐蚀产物对钚的吸附行为研究,可为准确预测钚的迁移行为和处置库安全评价提供理论基础。本文综述了废物地质处置条件下包装容器材料可能的腐蚀机理,系统总结了腐蚀产物对钚的吸附行为、影响吸附的主要因素以及吸附机理等方面的国内外研究进展,为今后深入研究腐蚀产物对钚的吸附机理提供参考。

Review of Sorption of Pu on Corrosion Products of Low Carbon Steel Container

It is important to study the corrosion mechanism of low carbon steel container and the adsorption behavior of plutonium by corrosion products for evaluating the safety of radioactive waste disposal sites. The study of corrosion behavior of low carbon steel packaging container in radioactive waste repository and the adsorption behavior of corrosion products on plutonium can provide theoretical basis for accurate prediction of plutonium migration behavior and safety evaluation of repository. In this paper, the possible corrosion mechanism of packaging container materials is summarized under the condition of waste geological disposal, and the adsorption behavior of plutonium on corrosion products, the main factors affecting the adsorption and the adsorption mechanism are systematically summarized, which provides a reference for further study on the adsorption mechanism of plutonium on corrosion products in the future.
