What’s reshaping nuclear licensing and compliance today?
Mark Reidmeyer
It is the convergence of urgency, innovation, and modernization that is reshaping nuclear licensing and compliance today.
For decades, nuclear licensing operated in a relatively stable environment built around large light water reactors, predictable review cycles, and well-established regulatory pathways. Today, that model is evolving rapidly. Advanced reactors, AI-enabled tools, digital engineering platforms, grid reliability concerns, and aggressive decarbonization goals are all pushing the industry—and regulators—to move faster and think differently.

The feasibility of using a fast pulse reactor as a neutron source in the production of time-resolved neutron radiographs has been demonstrated at the U.S. Army Pulse Radiation Facility. The radiographs were obtained using the transfer radiographic method. Pulses with a full width at half maximum of 50 µsec and 1.2 × 1017 fissions were utilized to obtain time-resolved radiographs of objects moving at speeds up to 76 m/sec. Investigation of double images, observed in radiographs of test objects moving within this speed range, suggests a method of producing “motion pictures” of these objects using one reactor pulse and a suitable stack of detection foils. Resolution of objects moving at speeds greater than 76 m/sec can be obtained by reducing source exposure time to a lower limit of 1 µsec through employment of electronic gating and image intensification techniques.
