Abstract

The uniqueness of the Canadian spent nuclear fuel disposal container design requires a detailed understanding of the copper corrosion processes that could occur in deep geological repositories. This review aimed to identify knowledge gaps surrounding impacts of changing conditions and the evolution of corrosion processes as conditions change from moist/cool, through warm/dry, to cool/fully saturated. This review indicates that early, unsaturated corrosion, and compounding influences of previous corrosion are understudied.

影响处置乏核燃料的镀铜乏燃料容器的腐蚀过程:对现有知识状况的批判性审查
加拿大乏核燃料处理容器设计的独特性要求详细了解深层地质储存库中可能发生的铜腐蚀过程。这篇综述旨在确定随着环境从潮湿/凉爽、温暖/干燥到凉爽/完全饱和变化,环境变化对腐蚀过程的影响和演变的知识差距。这一综述表明,早期的不饱和腐蚀以及先前腐蚀的复合影响还有待研究。

期刊介绍: npj Materials Degradation considers basic and applied research that explores all aspects of the degradation of metallic and non-metallic materials. The journal broadly defines ‘materials degradation’ as a reduction in the ability of a material to perform its task in-service as a result of environmental exposure. The journal covers a broad range of topics including but not limited to: -Degradation of metals, glasses, minerals, polymers, ceramics, cements and composites in natural and engineered environments, as a result of various stimuli -Computational and experimental studies of degradation mechanisms and kinetics -Characterization of degradation by traditional and emerging techniques -New approaches and technologies for enhancing resistance to degradation -Inspection and monitoring techniques for materials in-service, such as sensing technologies
