In large, complex process systems such as nuclear power plants, annunciation is used to alert operations staff to important changes in plant conditions that may affect operational goals. Annunciation, along with the routine monitoring of control room displays, enables operations staff to keep up to date with the current plant conditions and predict future plant states. Major plant upsets result in annunciation of hundreds of process and equipment state changes. These large numbers of messages may overload the presentation capacity of annunciation media and the ability of operations staff to assimilate them. The task analysis described in this paper is one of several activities undertaken as part of a Canadian research program to develop an improved strategy and architecture of CANDU plant annunciation.
