采用乙醇胺抑制核电站二回路系统的流动加速腐蚀
摘要
分析目前国内压水堆核电站二回路流动加速腐蚀的原因。通过试验室试验和实际应用试验
证明乙醇胺能够明显提高汽水两相流中水相的pH值
可有效抑制二回路的流动加速腐蚀
并能够延长凝结水精处理混床的运行周期。试验没有发现乙醇胺对系统的不良影响。
Abstract
The causes leading to flow-accelerated corrosion(FAC) in secondary system of domestic pressurized water reactor nuclear power stations have been analysed.Through tests in the laboratory and in practical application
it shows that the Ethanolamine(ETA) can significantly ehhance the pH value in water-phase of steam-water two-phase flow
and effectively inhibit the FAC in the secondary systems of nuclear power stations.The negative influence of ETA upon the systems hasn't been discovered in said test.
