Study on Application of Ethanolamine in NPP Secondary Water Treatment

Science and Technology on Reactor System Design Technology Laboratory, Nuclear Power Institute of China, Chengdu, 610041, china

摘要: 乙醇胺(ETA)是一种碱性有机胺,碱度和挥发性优于氨。对ETA在二回路的应用进行研究,并对其在系统中的分布进行计算分析。经论证,采用ETA的水处理,能够有效提高蒸汽水分(液滴)和凝结水的pH值,减少流动腐蚀的危害,降低二回路材料的腐蚀速率,延长蒸汽发生器和二回路设备的使用寿命,提高在役核电厂的经济性。该工作对国产核电厂二回路水处理技术改进具有参考价值。

Abstract: Ethanolamine(ETA) is an organic amine which has stronger alkalinity and lower volatility than ammonia.The paper analyzes the influence of ETA used in the secondary system and calculates its distributing status at the different nodes of the secondary system.The study shows that ETA can enhance the pH value in liquid phase of vapor-liquid two phase regions,effectively inhibit the flow-accelerated corrosion,reduce the corrosion rate of the secondary system materials and improve the economy of the in-service nuclear power plants.It is concluded that ETA as a pH additive to the secondary side of pressurized water reactor is completely viable.
