New Applications of Video Camera Smoke and Flame Detectors in Canadian Nuclear Facilities

Abstract

Alternative Compliances have been approved by the Canadian Nuclear Safety Commission (CNSC) for the installation of new video smoke and flame detecting cameras in both the Darlington and Bruce Nuclear Generating Stations (NGS). This technology improves event detection response time and accuracy in challenging building areas where normal techniques are not feasible. These locations are characterized by large open spaces, complex room geometries, high airflow, and areas where smoke stratification prevents smoke from reaching traditional spot detectors. Current and future applications of this technology is discussed, including the impact of earlier detection on asset protection. A review of non-nuclear industry Operating Experience (OPEX) has been included. Facility operators can also utilize the camera live video capabilities to observe an event site prior to initiating fire mitigation strategies. This improves the safety and effectiveness of responders as well as allowing remote visual confirmation of nuisance alarms.
