A Study on Evaluation Method About Human-Machine System Interface for Nuclear Power Plant

Now the new control technology has been used in industry including the main control room design of nuclear power plant (NPP). Although We have designed the computerized human-machine system interface (HSI) in Ling Ao Phase II NPP, the old evaluation method about HSI can not be used for the new one. Based on this experience together with reference to the other published information such as NUREG-0700 Rev.2, this study have developed an evaluation method based on a model of human cognitive processes in order to provide the viewpoint of the evaluation on the operability of interface. The method describes systematically the human error categories and evaluation items for HSI. And the method has been evaluated using the evaluation of experimental results obtained by a simulator equipped with computers and touch operation control panels.
