摘要：
Computer-based soft control has been applied in advanced main control rooms (MCRs) for supervision and control of nuclear power plants. Compared with traditional MCRs based on analog technologies, man-machine interfaces and interactions in advanced MCRs have been significantly changed. In this study, taking the chemical and volume control system (CVCS) in a pressurized water reactor as an example, the tasks of operating procedures involving 19 subtasks and 70 steps for starting the CVCS under a normal shutdown operation condition are firstly analyzed. Furthermore, eight potential failure modes are identified when the operators executed each step of the operating procedures. The correlations between subtasks are also analyzed. Case studies are conducted for quantitatively estimating the human error probability of each subtask and the task as a whole. Finally, the effects of supervising soft control and improving man-machine interface on the reduction of human errors are discussed.The research results show that the human error probability could be reduced significantly by the means of improving the operator's skill, introducing the substitution operating procedures, conducting supervision on each complex task and continuously improving the human machine interface. © 2016, Editorial Department of Journal of HEU.
