Approach to the Analysis of Success Criteria as a Component of Probabilistic Physical Protection Analysis of Nuclear Facilities

An approach to adapting the methodology for analyzing success criteria from traditional probabilistic safety analysis (PSA) of nuclear power plants (NPPs) to probabilistic physical protection analysis (PPA) of nuclear facilities is demonstrated using the hypothetical nuclear facility SNRI as an example. Generally speaking, using the traditional PSA methodology for assessing the physical protection of nuclear facilities allows for the identification of new vulnerabilities in the physical protection systems of nuclear facilities, the development of recommendations to enhance physical protection efficiency, the performance of more substantiated cost-benefit analyses, and more.
