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 fission-gas release from UO2 samples was studied during irradiation in the temperature range 150 to 2000° C. Both sintered UO2 and single crystals were studied. Below 600° C, recoil and knock-out are the mechanisms of release. Between 800 and 2000° C, excluding the evaporational escape above 1800° C, the fractional release follows an Arrhenius law where activation energy decreases with increasing density. The fractional release was found to be independent of neutron flux.
