Proceedings of the International Atomic Energy Agency Specialists' Meeting on Experience and Improvements in Advanced Alarm Annunciation Systems in Nuclear Power Plants. Held in Chalk River, Canada on September 17-19, 1996

摘要

The meeting was held within the framework of the program of the International Working Group on Nuclear Power Plant Control and Instrumentation, and was convened with the support of Atomic Energy of Canada Limited and the CANDU Owners Group. The topic for this meeting is alarm annunciation. Annunciation is used to ensure that control room staff are promptly alerted to important changes in plant conditions that may impact on safety and production goals. Traditional annunciation systems incorporate alarms derived directly from plant analog and binary data. The need to improve alarm annunciation systems in nuclear power plants was recognized about two decades ago. It was the Three Mile Island accident in 1979 that triggered a large research effort throughout the world. Since then, the requirements for control rooms and human machine interfaces, including annunciation, have changed dramatically as a result of: evolution of new standards for control room design; technological advances in information processing and presentation; and the evolution of licensing requirements that take increasing account of human factors engineering. The objective of the meeting is to provide an international forum for the presentation and discussion on R&D, in-plant experiences and improvements to annunciation systems.
