压水堆核电站高能管道破裂动态效应消除方法及应用

Summary of the Methods to Eliminate Dynamic Effect of High Energy Piping Break in PWR

在压水堆核电站的设计中需要考虑管道破裂产生的动态效应,这些动态效应会使相关的管道、设备和构筑物中产生非常大的动态载荷,这些载荷不仅提升了电站的设计难度,还直接影响电站的经济性和安全性。本文介绍了几种常用的消除高能管道破裂动态效应的方法,通过这些方法的应用可以减少甚至不再考虑管道破裂动态效应,可以简化核电站设计。本文介绍了几种方法各自的特点、应用范围,并对其在在役电厂应用的可行性给出了建议。

The dynamic effect of high energy piping break should be considered in the design of PWR,which may induce a large load in concerned piping,equipment and structures.The dynamic effects bring a lot of trouble in design of plant,and reduce economy and safety of the plant.This article describes a few com⁃mon methods which can be used to eliminate the dynamic effect of piping break.This paper introduces the characteristics of each of these methods,the scope of application,and provides suggestions for the rational use in operating plant.
