核电厂设备及管线保温层下腐蚀与防护技术

摘要

the equipment and pipelines insulation is widely used in the nuclear plant. With the operation time of the plant increased, Corrosion under insulation (CUI) is a swelling problem. Combined with the practical operation of plant and investigating the corrosion under insulation mechanism, monitoring technology and protecting measures, the suggestions and solutions are provided to solve CUI problems in the nuclear power plants.%核电厂设备及管线保温装置普遍。随着机组运行时间增加，保温层下腐蚀（CUI）问题日益严峻。结合核电厂实际运行工况，针对保温层下腐蚀机理、监测技术及防腐措施进行调查研究，对在役核电厂解决CUI问题提出建议及方案。
