| contents | Advanced nuclear reactor systems face increasing cybersecurity threats as sophisticated attackers exploit cyber-physical interfaces to manipulate control systems while evading traditional IT security measures. This research presents a comprehensive evaluation of artificial intelligence approaches for cybersecurity protection in nuclear infrastructure, using Argonne National Laboratory's Mechanisms Engineering Test Loop (METL) as an experimental platform. We developed a systematic evaluation framework encompassing four machine learning detection paradigms: Change Point Detection, LSTM-based Anomaly Detection, Dependency Violation analysis, and Autoencoder reconstruction methods. Our comprehensive attack taxonomy includes 15 distinct scenarios targeting reactor control systems, each implemented across five severity tiers to evaluate detection performance under varying attack intensities. The experimental evaluation encompassed 300 rigorous experiments using realistic METL operational data. Change Point Detection emerged as the leading approach with mean AUC performance of 0.785, followed by LSTM Anomaly Detection (0.636), Dependency Violation (0.621), and Autoencoder methods (0.580). Attack detectability varied significantly, with multi-site coordinated attacks proving most detectable (AUC = 0.739) while precision trust decay attacks presented the greatest detection challenge (AUC = 0.592). This work delivers practical performance benchmarks and reference architecture that advance AI-based cybersecurity capabilities for critical nuclear infrastructure, providing essential foundations for operational deployment and enhanced threat response in cyber-physical systems. |
