核电厂功率快速变化下操纵员任务分析

从操纵员培训、任务类型和工作负荷3个方面，对比分析核电厂调峰任务与其他常规工况下操作任务存在的差异性。通过对比得出，调峰任务和常规工况下操作任务相比，操纵员心理负荷和体力负荷将发生较大改变，这将导致操纵员的认知模式和人因失误模式相较于常规工况存在差异。现有的人因可靠性分析（HRA）方法和模型难以满足操纵员人因可靠性分析的需求，因此需要建立一种新的HRA方法解决操控任务持续快速变化背景下核电厂操纵员人因可靠性问题。 

Analysis of Operator's Task under Rapid Power Change in Nuclear Power Plants

The differences between the peak load and the operation task in the normal operating conditions of the nuclear power plants are compared from three aspects of operator training, task type and working load. Compared with the operation tasks under the normal working conditions, the mental load and the physical load of the operators would be changed greatly, which would lead to the difference between the operator's cognitive model and the human error mode compared with the conventional working condition. The existing HRA methods and models are difficult to satisfy the operator's reliability analysis, so a new HRA method is needed to solve the problem of the reliability under the background of continuous and fast changing of control tasks in the nuclear power plants.
