Alarm and status processing and display in the Nuplex 80+ Advanced Control Complex

The development of a nuclear power advanced control room includes the improvement of previous generation alarm system designs. The Nuplex 80+ Advanced Control Complex alarm methodology utilizes redundant and diverse fixed-location and CRT alarms. These alarms are grouped by panels and presented on system and function display pages to support operator tasks. Plant operational mode-dependency, prioritization, signal-validation and equipment status dependency are used to improve alarm validity, and to reduce and organize alarms. Human engineered visual and audible cuing support prioritization and reduce distractions for new alarms. Critical function and success path alarms directly support operator procedures for power production and emergencies.<>
