The Application Of Ethanolamine In Secondary Water Chemistry For Steam Generator In Nuclear Power Plants

The tube degration of steam generator(SG) is often occurrence, it seriously impact the safety operation of SG, The key to solve the problem lies in The secondary system chemistry control.The purpose of this experiment is to analyze the function of resisting corrosion of ETA towards to equipment materials of steam generator's secondary side, under dynamic condition. This paper explains corrosion theory of metals and analyzes functional mechanism of ETA and the corrosive characteristic of steam generator in nuclear power plant, analyzes the debugging result of the experimental system and checks thermo-dynamical and hydraulic term of this system and estimates the parameters each before and after the experiment. The result shows that this experimental system runs steadily and safely and it can imitate operational mode of work quality in steam generator's secondary side in nuclear power plant, and the statistics getting from this system are reliable.The performance of ETA in resisting corrosion is better than Ammonia.
