中压蝶阀导致的核电机组满功率孤岛试验不成功原因分析及临时处理措施

Analysis of Failure of FCB Test Led by IP Inlet Valves in Nuclear Turbine and Emergent measures

文章针对核电机组做满功率孤岛试验不成功进行原因查找及具体分析,结合机组特点,将满功率孤岛试验(FCB)瞬态过程简化并带余量估算,基于估算得出结论,最终为机组采取临时处理措施,从而为业主避免损失。

In this article,the reasons for the failure of the full power fast cut back(FCB)test of nuclear power units are searched and analyzed in details.Combined with the characteristics of the units,the transient process of full power FCB test is simplified and margin estimation is carried out.Based on the estimation,the conclusions are drawn,and the temporary treatment measures are finally taken for the unit,so as to avoid losses for the owner.
