“…Thus, potential human errors and associated system configurations are about to be identified through the reliability-based mapping scheme. As a graphical modeling tool, the GO-FLOW has been applied to a wide range of applications, such as elevator safety analysis [55], risk analysis of dynamic behavior of nuclear power plant under severe accident condition [56], Living PSA [57] reliability monitor [58] and risk monitor [59], etc. In 2012, T. Matsuoka applied the GO-FLOW method for quantitative evaluation of operator team's response in a pressurized water reactor incident [61].…”

In the paper we present a reliability-based mapping scheme for underlying erroneous human behavior recognition with the intention of retrospective operational audit and safety management in nuclear power plants. For implementing the reliability-based mapping scheme, a success-oriented GO-FLOW method is applied to model, quantify and identify the erroneous human behaviors and associated system configuration changes. The retrospective investigation of human error is illustrated with a simulated example case event of loss of dual residual heat removal pumps during the refueling outage of nuclear power plants. The case study shows that human-system configuration changes in multiple task sequences can be easily captured by GO-FLOW method for post-hoc reviewing analysis.INDEX TERMS Human error, operational audit, reliability mapping analysis, GO-FLOW, nuclear power plants.
