摘要
反应性控制是核电厂安全功能之一,为提高核电厂安全性,满足第四代核能系统安全性的要求,非能动停堆技术已成为重要研究议题之一。国际上研究较多且技术相对成熟的的非能动停堆系统主要有4种方式,中国目前正在进行基于液体悬浮原理的非能动停堆装置的研发工作,由于液体悬浮式控制棒驱动机构特殊的结构、工作方式和控制要求,需设计和研发适用的仪控系统。本文介绍了目前正在研发的液体悬浮式控制棒驱动机构控制系统的设计方案,后续还将进行一系列验证工作,以满足指标要求。
Reactivity control is one of the security functions of nuclear power plant.In order to improve nuclear power plants'safety while satisfying the safety requirement of the fourth generation nuclear power system,passive shutdown technology has become one of the important research issues.There are four kinds of passive shutdown systems which are researched commonly and relatively mature in the world.China is researching and developing its passive shutdown system based on the principle of liquid suspension.Because of the special structure,operating mode and control requirement,it is necessary to design and develop the applicable I&C system.It describes the control system which is being developed at present.What’s more,in order to meet the requirements,a series of verification will be carried out later.
