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.

CASL is the first U.S. Energy Innovation Hub connecting fundamental research and technology development through an integrated partnership of government, academia, and industry. CASL.s objective is to provide leading edge modeling and simulation (M&S) capability to improve the performance of currently operating light water reactors and its vision is safer and more productive commercial nuclear power production afforded through comprehensive science-based predictive M&S technology. Towards that end, CASL is developing the Virtual Environment for Reactor Applications (VERA). VERA software simulates nuclear reactor physical phenomena using coupled multi-physics models and includes a range of physical domains, from microscale to engineering scale. VERA's current physics capabilities include neutron transport, thermal-hydraulics, fuel performance, and coolant chemistry.
