Proposed design of displays to monitor the status of the safety systems and safety-related systems

The report is focused on displays suitable for monitoring the status and performance of hydroaccumulators at the Dukovany NPP and on the inclusion of this subsystem into the emergency core cooling system. It is demonstrated how a hierarchically arranged display system can be designed to enable the status of safety-related systems to be evaluated rapidly, reliably and with a high level of automation, and how this display system can be used within the assessment of the capability of a reactor unit to cope with various types of accident.
