在核电站中,蒸汽发生器的部份U形管常常需要堵管。本文分析了蒸汽发生器的部份U形管被堵后继续运行对反应堆热工设计安全性能的影响,并予计这种影响的程度;文内还讨论了与此相关的一些问题;最后简略地提出了对蒸汽发生器的设计改进意见。
In nuclear power plants, some of the U-shaped tubes of the steam generator often require plugging. This article analyzes the steam generator part of the U-shaped tube is blocked and then continue to run on the thermal design of the reactor safety performance, and to calculate the extent of this impact; text also discussed some of the issues related to this concise Proposed to improve the design of the steam generator.
