大亚湾核电站主蒸汽安全阀定值漂移解决方案研究

Solution of Main Steam Safety Valve Setting Drift in Daya Bay Nuclear Power Plant

介绍大亚湾核电站主蒸汽安全阀发生的压力整定值漂移问题,分析导致安全阀压力整定值产生漂移的原因,结合法国EDF核电站针对同类问题的解决方法,提出大亚湾核电站解决主蒸汽安全阀压力整定值漂移的方案。

This paper introduces the pressure setting drift problem of main steam safety valve in Daya Bay NPP, and also analyses the reason leading to pressure setting drift. By combining the solution of similar problems in French EDF plant, solutions are proposed for the pressure setting drift problem of main steam safety valve in Daya Bay.
