Efficacy of Group-View Displays in Nuclear Control Rooms

Group-view displays (GVDs) have become prominent features in modern nuclear control rooms (NCR). Despite widespread implementation, their efficacy has yet to be thoroughly evaluated. This paper presents a full-scale nuclear simulator study that compared the current state of the art in NCR GVDs against experimental alternatives. The results indicate that the current state of the art in NCR GVDs can be improved upon. An experimental display configuration (redundant displays) yielded higher communication scores than the standard NCR GVD configuration (large-screen displays). Furthermore, operators using experimental display types (ecological displays) exhibited superior situation awareness compared to those using contemporary NCR displays (advanced displays). The implications, limitations, and recommendations for future work are discussed.
