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.

Concepts being developed for tritium containment at proposed fusion power plants will rely on existing laboratory experiences. The successful operation of a glove-box containment system was demonstrated by the control of an accidental release of 0.65 PBq (1.75 × 104 Ci) of tritium to the glove-box atmosphere. The total gaseous release to the environment was 79 ± 10 GBq (2.2 Ci). In addition, the tritium concentration in the body fluids of the sole worker in the laboratory increased by only 74 kBq/ℓ (2 µCi/ℓ). The appearance rate of tritium in the room and the absorption of tritium by the worker were adequately described by permeation of the molecular species of T2 and HTO through the gloves.
