Trouble analysis and handling for solenoid pilot valve disc

ZHOU Xing-qiang(Jiangsu Nuclear Power Corporation,Lianyungang 222042,China)  
This paper present the working principle of the solenoid pilot valves for main steam relief isolation valves of Tianwan Nuclear Power Plant,the research on root cause for solenoid pilot valve disc damage due to the vibration were carried out and the conclusion of the failure were reached.The countermeasures were decided and the modification were performed accordingly.
