Author’s note: The focus of this article is how to conduct a fire risk assessment for heavy water nuclear reactors, including the CANDU (CANada Deuterium Uranium) reactor, a Canadian-invented, pressurized heavy-water reactor used for generating electric. Five risk-assessment methodologies from standards that are widely accepted in the industry are discussed in this article and examined to conclude the best method to be used and the required future work needed to perform such an assessment.
核反应堆代表potential for major catastrophic events; therefore, preventing a reactor failure is a major priority that entails multiple considerations and evaluations that involve factors such as design, fire protection issues, and structural integrity, to name a few. Adding to the potential hazards is the fact that natural disasters, such as earthquakes, can precipitate a disaster involving a reactor.
