Development of a Potential Facility Risk Index for Nuclear Safety and Security Using a Terrorism Scenario with a Hypothetical Nuclear Facility

Risk assessment involves analyzing potential accident scenarios to identify hazards and assess associated risk factors. Nuclear safety and security both aim to protect against radiation exposure, but they have developed separately with distinct risk assessment methodologies. As a result, there is a need for a comprehensive risk assessment method that covers both the safety and security aspects. The Potential Facility Risk Index (PFRI) was developed in 2020 to provide a quantitative approach to evaluating the security risk of nuclear facilities, but it does not consider safety risks.
