Before a nuclear facility can be constructed, it must undergo rigorous analysis to ensure that the facility is secure against outside threats and that the facility can maintain operational safety. Traditionally, these safety and security analyses have been conducted separately, as if in a vacuum, despite the fact that security and safety can have significant impact on each other. In the post-Fukushima nuclear industry an emphasis has been placed on investigating situations that are beyond the original design basis, probing to find the vulnerabilities that have previously gone unexamined. This work seeks to develop a methodology to analyze how the overall security risk changes as a result of initiating safety events.
