Development of Improvements to CANDU Computerized Annunciation.
Abstract:
Canadian nuclear utilities and AECL have successfully completed a multi-year development program to improve the computerized control centre annunciation in CANDU nuclear power plants. The outcome of this program has been the definition and validation of an improved strategy for CANDU annunciation. The alarm processing, presentation and interaction concepts comprising the strategy have the potential to significantly improve station economic performance, are retrofitable to current plants, and are being incorporated into new CANDU plant designs.
This paper outlines the key program activities, the specific improvements developed, and the significant operational benefits realized by theses annunciation improvements. The paper also summarizes the lessons learned in developing these annunciation improvements and describes the progress underway to apply these improvements to current CANDU plants on a retrofit basis and to new CANDU plant designs.
