- 摘要:
- AP1000核电站钢制安全壳是核岛关键设备,其涂层不仅仅为了防腐,更多的是为了核电站的安全运行。主要介绍了AP1000钢制安全壳及其附件涂层服役分级和涂层技术要求。对现场钢制安全壳涂层施工重点技术要求和不符合项进行了总结分析,提出在钢制安全壳相关涂层施工时,需着重注意贯穿件涂层的施工问题,以及技术规格书要求的"不可达区域"严格的许可。通过分析总结,为后续项目AP1000核电站钢制安全壳的防腐和防辐射涂层的施工提供参考。
- Abstract:
- AP1000 containment vessel is key equipment of nuclear island,coating on the vessel is not only for anti-corrosion,but also for safe operation of the nuclear power plant.This paper introduced coating service level and coating technical requirements of the AP1000 Steel Containment Vessel and its attachments.At the same time,key technical requirements and non-conformities of coating construction issues were analyzed.It was also pointed out that the coating quality control needed to focus on penetration assemblies and strict " unreachable area" definition in technical requirements.Through the analysis and summary in this paper,it try to provide a reference to anti-corrosion and anti-radiation coating operation for the AP1000 containment vessel in follow-up projects.
