Abstract

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.
