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 Marx generators, with a total stored energy of 26.4 MJ and a diode voltage of 10 or 5 MV, supply the energy to diodes to extract proton beams. A combination of two types of diodes is used. One diode type is insulated by the radial magnetic field and extracts the rotating ring beam. The other type is the ordinary magnetically insulated one, from which the proton beam fills the inner hollow part of the rotating beam. The argon gas filling the reactor cavity neutralizes the charge of the proton beams, but does not neutralize the current of the beams. The proton beam pinches to a small radius by the azimuthal magnetic field, and its propagation is stabilized by the axial magnetic field. The cryogenic 6-mm-radius hollow shell target consists of three layers of lead, aluminum, and deuterium-tritium fuel. The target is imposed by a biased voltage of −1 MV in order to focus the proton beams on the target surface. The ion temperature and pR of the fuel after the target implosion reach 4.2 keVand 7.0 g/cm2, respectively. Thus the 2.5-GJ output energy is released from a target. The reactor is an ADLIB type, which consists of an inner rotating cylinder and an outer fixed cylinder. Inside the inner rotating cylinder, the Flibe flows, acting as coolant and tritium breeder. The net plant efficiency is expected to be 33%, and the 800-MW(electric) net power can be supplied from one reactor with a 1-Hz operation frequency.
