叙述了核电厂安全参数显示系统中的安全参数选择与论证的方法和结果。根据核电厂安全分析,将核电厂的全面安全分解成六个关键安全功能,并严格选择了能够反映各安全功能的完整程度及其变化原因的安全参数。从使用核电厂应急规程的角度,并用全范围核电厂模拟器的事故演习对安全参数选择进行了论证。 The method and result of safety parameter selection and demonstration in nuclear power plant safety parameter display system are described. According to the analysis of nuclear power plant safety, the comprehensive safety of nuclear power plant is decomposed into six key safety functions, and the safety parameters which can reflect the complete extent of the safety functions and the causes of the changes are strictly selected. From the point of view of using emergency procedures of nuclear power plants, the safety parameter selection was demonstrated with the accident maneuvers of the full range of nuclear power plant simulators.
