基于系统动力学的场外核应急洗消设备配置问题研究

洗消设备配置问题是场外核应急准备工作的重要环节之一,论文根据核辐射洗消过程运行特点,考虑系统内人群密度对洗消进程的影响关系,建立洗消系统系统动力学模型。在不同核辐射超标率场景中,设计不同设备配置方案,模拟并观察系统内等待人数和总洗消时间的变化。仿真结果表明,检测I设备与洗消设备的配置数量及比例,影响洗消进度;在综合考虑设备投入和洗消站占地面积的条件下,该方法可为场外核应急洗消设备配置提供决策依据。

Study on Decontamination Equipment Allocation during Off-site Nuclear Emergency Based on System Dynamics

The problem of decontamination equipment allocation is one of the important links of off-site nuclear emergency preparedness. This paper establishes the decontamination system dynamics model, according to the operation characteristics of radiation decontamination process and considering the influence of crowd density on the decontamination process. We simulate and observe the change of the waiting people’s number in the system and total decontamination time, through designing different equipment allocation scheme within different radiation scenarios. The simulation results show that the number and proportion of detection I and decontamination equipment allocation would influence the decontamination progress. This method can provide decision-making basis for off-site nuclear emergency decontamination equipment allocation considering the equipment’s cost and decontamination area conditions.
