Digital Substations: Cyberattack detection system for small modular reactor-based power plants.
Bibliographic record
Abstract
Small modular nuclear reactors (SMRs), with capacities under 300 MWe, are proposed as potential solutions to various challenges in nuclear power, such as economic viability, safety, proliferation risks, and waste management. Their compact size makes them ideal for areas with limited grid capacity and allows for flexible energy generation and integration with renewable sources, which is increasingly essential for developing economies. However, the cyber security of SMRs is vital due to their importance in national infrastructure and potential vulnerabilities within their supply chains, which could lead to serious safety and operational disruptions from cyber-attacks. The risk is compounded by blended attack strategies, where physical and cyber assaults are executed simultaneously, highlighting the need for robust cyber security measures as outlined by the International Atomic Energy Agency. In response, this article discusses the cyber security challenges faced by SMR-based power plants, presenting a system that analyzes the impacts of cyber-attacks on these reactors within smart grid frameworks. It employs real-time simulators to emulate power and communication behaviors and introduces a Cyber-Attack Detection System (CADS) utilizing machine learning algorithms to detect threats early in their progression.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
