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.

Measurements were made of the viscosity of Columbia River basalt and basalt-urania melts containing up to 18 wt% UO2 in the temperature range 1360 to 1960°C. A concentric cylinder-type viscometer was used. The combined data were fit by the equation, where η is viscosity in poise, T is temperature in degrees Kelvin, and X is the weight percent UO2 in the melt.
