원자력 분야의 리스크정보활용 현황과 과제

We often talk about the 'safety' of complex industrial facilities such as nuclear power plants, but safety is a concept that cannot be measured quantitatively by engineering. In order to quantitatively measure the safety of large facilities, the concept of 'risk' is necessary. The fact that risk assessment and management techniques can most effectively and efficiently improve the safety and performance of nuclear power plants has been proven over the past several decades of US nuclear power plant operations. This paper introduces the concept of risk and briefly explains the background to its introduction in the nuclear community. It also introduces the probabilistic safety assessment (PSA) method, a widely used risk assessment method in the nuclear community. Next, we introduce a risk management framework for effectively and efficiently reducing the risk of nuclear facilities using the risk assessment results. Finally, we briefly discuss how to communicate the results of risk assessment and management to society.
