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.

Twelve experimental runs on molecular iodine removal by sprays were carried out in the 95m3 PSICO 10 model containment vessel (MCV). Both service water and a water solution containing 1% sodium thiosulphate were sprayed through two different nozzles; the elemental iodine removal half-times obtained by spraying service water do not differ greatly from those found by spraying thiosulphate solution. The sprayed solution was, in some cases, recirculated for a period ranging from 1 to 11 h without any release of iodine to the atmosphere. Some runs were performed with fractions of the MCV volume not sprayed. The elemental iodine removal half-times in the sprayed and unsprayed regions do not essentially differ.
