4.1.3-1 Prioritization Criteria

Alarm messages should be presented in prioritized form to indicate urgency (immediacy of required action) and challenges to plant safety.

Additional Information:
Additional alarm priority dimensions, such as challenges to plant productivity or investment protection, may also be implemented. The selected prioritization scheme should be logical such that those alarms of the highest safety significance receive the highest priority and such that the prioritization appears reasonable to operators.
