Investigation of potential operation issues of human-system interface in Lungmen Nuclear Power Project

The Lungmen Nuclear Power Project (LMNPP) with 1350 MWe twin units is the first advanced boiling water reactor (ABWR) project in Taiwan. Video display units are the main human-system interface for operator to manipulate, i.e. so-called "soft" control, and to know the status of the equipment and plant information. Several concerns have been identified as compared to hard controls. These concerns led us to conduct an investigation of the operator's performance and the potential issues about operator's teamwork. The investigation results show that the most important task is to establish an intensive training program to address the knowledge and skill requirements of the operators to meet the task characteristics and the responses of the plant processes.
