| Abstract | This paper studied to employ a top-down approach to human factors engineering process in nuclear power plants. The success paths were developed by the function modeling and applied to control room design in nuclear power plant. In the current design practice, the success paths are used for human factors engineering analysis. In this study, new design countermeasure was applied for operating procedures and control room displays using the success paths employed by the function modeling approach. It is effective for operator to be able to monitor current function status as well as available alternatives to control functions so that operator can select alternative success path as quickly as possible if the working success path are failed. The human controller model was applied in system theoretic accident model and process/system-theoretic process analysis, and potential human errors were identified for nuclear power plants. Human controller model allows practitioners of human reliability analysis to improve identifications of crew failure mode/human failure events in the current scenario-based approach of the human reliability analysis.
