摘要
主要描述了RRA系统进口死管段问题产生的背景,初步探讨了现象产生的原因,在考虑了阀门本体的特征基础上提出了一种改进方案,初步计算和分析了采用优化方案后对系统和机组运行的影响,可以看出,对机组的运行带来的影响是很小的,改进方案是可以接受的。
The background of dead leg problem of RRA system is described in this article,and the cause of the phenomena is preliminarily studied.Based on the valve's interior characteristics,an improved method is proposed.The effects of using the improved method on system and plant operation are calculated and analyzed.In conclusion,the effects on plant operation are very small and the improved method is acceptable.
