摘要
核电厂蒸汽发生器(SG)水位控制系统的安全可靠运行是保证核电厂安全性和经济性的关键因素,其控制对象具有高度复杂、非线性的特点。由于复杂系统的安全性是特定环境下由系统相关要素交互作用所产生的一种涌现特性,运用系统理论,以STAMP模型为基础对SG水位控制系统进行安全性分析,以利于在设计早期阶段发现影响该系统安全运行的潜在风险因素,预防危险事故。该方法将系统理论用于核电厂关键系统和设备安全性分析,为核电厂安全运行提供了新的技术手段支持。
The reliable operation of water level control system for steam generator （ SG ） , the control objects of which have characteristics of highly complex and non-linear , is the key factor to guarantee the security and economy of nuclear power plant .According to emergent property produced by the interaction relevant elements of SG water level control system , the system theory and STAMP model were applied to analyze the system security and discover the potential risk factors affecting safe operation of the system .The method of applying systems theory in security a-nalysis of critical systems and equipment in nuclear power plant provides a new technical support for the safe opera -tion of nuclear power plant .
