摘要
为了保障海上浮动核电站的安全运行,利用人员认知可靠性(HCR)模型,分析海上浮动核电站的人因可靠性。首先通过分析和量化海上微气候、噪声、船体运动等外部因素对操纵员的操作速度和准确度的影响,修正HCR模型;然后以海上浮动核电站失水事故(LOCA)为例,分析事故中涉及人员行为以及事故处理流程,根据事故发生的情景对各计算参数取值;最后计算操纵员对反应堆LOCA事故系统异常信号认知和响应的失败概率。结果表明:计算结果与实际较为吻合,修正后的HCR模型可操作性较强。
In order to guarantee safe operation of marine floating nuclear power plants,human factor reliability of them is analyzed by using HCR model. Firstly,influence of external factors such as ocean microclimate,noise and hull motion on operating speed and accuracy was analyzed and quantified,and HCR model was modified. Then,with LOCA of marine floating nuclear power plants as an example,behaviors of people involved in the accident and their handling process were analyzed before values of calculation parameters were obtained according to accident scenarios. Finally, failure probability of operator’s recognition of and response to abnormal LOCA signals was calculated. The results show that calculated results are in good agreement with actual situation,and the modified HCR model has greater operability.
