  • The characteristics including dissociation, vapor-liquid distribution, thermal decomposition,compatibility with materials of ethanolamine(ETA) used in secondary system of nuclear power plant(NPP)were investigated by the laboratory research and full-scale testing at Nuclear Station. The results show that ETA does not only have strong base strength, low vapor-liquid distribution and good thermal stability, but also have an excellent compatibility with the secondary system materials. The application of ETA in the secondary system of NPPs can effectively decrease the concentration of ions in feed water and the amounts of slugs in steam generator(SG), and would make great significance to optimize the secondary water chemistry as well as reduce the corrosion rate of secondary system materials.
