Abstract:
Assessment of physical protection system effectiveness is the priority for ensuring the optimum protection from unlawful acts against a nuclear facility, such as unauthorized removal of nuclear materials and sabotage of the facility itself. Since an assessment based on real exercise scenarios is costly and time-consuming, the computer-based analytical tool can offer the solution for approaching the likelihood threat scenario. There are several currently available tools that can be used instantly such as EASI and SAPE, however for our research purpose it is more suitable to have the tool that can be customized and enhanced further. In this work, we have developed a computer–based analytical tool by utilizing the network methodological approach for modeling the adversary paths. The inputs are multi-elements in security used for evaluating the effectiveness of the system’s detection, delay, and response. The tool has capability to analyze for the most critical path and quantify the probability of effectiveness of the system as a performance measure.
