A Study on the Application of the Display Sharing Function In the APR1400 MCR

APR1400 digital Main Control Room (MCR) has been applied to Korean Nuclear Power Plants since Shin-Kori 3 and 4. APR1400 MCR has the advantages to reduce the physical and mental workload and to increase situation awareness through integrated information of Compact Operator Console, Computerized Procedure System (CPS) and Large Display Panel (LDP). But although digital MCR has many advantages, it has a weak point that operators cannot easily oversee other operator's operational behavior like soft control actions. This environment makes it difficult to perform concurrent and independent verification from the viewpoint of human error prevention. This paper presents the application method and design of display sharing function through combination using Large Display Panel (LDP) and Information Flat Panel Display (IFPD) of operator console for more reliable operation than before. Because display sharing function is applied within the Information Processing System (IPS), it is required to maintain the system requirement of the IPS such as the CPU and network load. For quality assurance, display sharing function will be developed in accordance with Human Factors Engineering program (NUREG-0711) and Software Program Manual (SPM). We expect that this technology strengthen the reliable operation of the APR1400
