Design and evaluation of computerized operating procedures in nuclear power plants

A small-scale virtual system has been developed in this study to enhance operators' understanding and operating performance. For this, a computerized graphical interface based on Dynamic Work Causality Equation (DWCE) has been designed to transform the operating procedure into a flowchart. Furthermore, the Programmable Logic Controller (PLC) was installed to connect the signboard (proposed system) with the computerized graphical interface. An experiment was conducted to verify the effect of computerized graphic interface, indicating that the computerized system significantly decreases learning time and improves operational performance.
