摘　　要：钢制安全壳在服役过程中无可避免地会发生老化，最为常见的三类老化现象分别为腐蚀、涂层降质和局部泄漏。文章介绍了这些老化现象的产生机理、危害以及相应的防护措施，并对AP1000钢制安全壳的老化管理提出了建议。Steel containment of the nuclear power plant will be inevitably aged during the servicing life. The top three types of aging mechanism to impact on steel containment degradation are shell corro- sion, coating degradation and local leakage, respectively. This article stated the aging forming conditions, damage effects and respective protective methods for the three types. For AP1000 nuclear power plant, the advices to conduct the aging management of the containment were also proposed at the end of this paper.
