Seconds Matter: Rethinking Nuclear Facility Security for the Modern Threat Landscape
In today’s rapidly evolving threat environment, nuclear facilities must prioritize speed and precision in their security responses—because in critical moments, every second counts. An early warning system serves as a vital layer of defense, enabling real-time detection of potential intrusions or anomalies before they escalate into full-blown incidents. By providing immediate alerts and actionable intelligence, these systems empower security personnel to respond decisively, minimizing risk to infrastructure, personnel, and the public. The ability to anticipate and intercept threats at the earliest possible stage not only enhances operational resilience but also reinforces public trust in the safety of nuclear operations. Investing in such proactive technologies is no longer optional—it’s essential for modern nuclear security.

For the purpose of making use a torus type magnetic confinement device as a high current electron source by extracting runaway electrons, we investigated magnetic fields' configuration and calculated electron orbits by numerical simulation. Extraction coils which generate field to lead electrons to outside of the device, also strongly disturbed magnetic field in partly installed case. We propose new cancellation coil setups. The numerical calculation shows influence of extraction coils are reduced, and as a results, the maximum radius of magnetic surface is almost the same as the case of setting up extraction coils all around device.We also traced the electron acceleration and extraction orbits from low energy in confinement area. Through that, we estimated the extraction ratio of the runaway electrons and their averaged energy. The results show that 70% of the runaway electrons can be extracted and the averaged energy of those electrons is 4 keV in case of all direction extraction.
