Dr. Neboyan has been unable to attend the meeting and sends his apologies. The meeting is being held within the framework of the programme of the International Working Group on Nuclear Power Plant Control and Instrumentation, and is convened with the support of Atomic Energy of Canada Limited and the CANDU Owners Group. On behalf of the Agency, I wish to also acknowledge the Government of Canada for hosting this meeting and for providing the opportunity for participants from many nations to attend the meeting to exchange their information and experiences. The topic for this meeting is alarm annunciation. As we are all aware, 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.
