秦二厂高加解列与GSS相关扫气疏水阀的讨论

在压水堆机组实际运行中,高压给水加热器解列是较为多发的瞬态。而汽水分离再热系统向高加的疏水不当又是造成高加解列的重要原因。本文从两系统的接口关系、逻辑联锁入手,分析多起实际运行中发生的高加解列事件,并将事件做延伸思考,重在讨论在运行工作中规避此类事件发生所需特别关注的点,强调严谨的工作态度和扎实的工作技能的重要性。此外,本文还对与此相关的技术改造做出了分析和探讨。

AHP-split is a common abnormal condition which often occurs in the actual operation of PWR.The error in the drain from GSS to AHP is a very important reason leading to the AHP-split.The author sets forth the relationship about equipment&logic between AHP and GSS in this paper.And then,the author analyses two incidents of AHP-split which really happened in order to tell how to avoid the recurrence of such incidents and emphasize the importance of the work attitude&job skills.In addition,the author also analyses the relevant technical reformation and takes a further consideration.
