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.

Two methods were developed for the determination of 236Pu in 238Pu. One method involves the direct measurement of 236Pu in the presence of 238PuO2. The second method consists of an indirect radiochemical determination of the ratio of daughter products from 236Pu and 238Pu (i.e., 232U and 234U). Both methods produce similar results, although each has its own distinct advantages.
