RIC session focuses on interagency collaboration
Attendees at last week’s 2026 Regulatory Information Conference, hosted by the Nuclear Regulatory Commission, saw extensive discussion of new reactor technologies, uprates, fusion, multiunit deployments, supply chain, and much more.
With the industry in a state of rapid evolution, there was much to discuss. Connected to all these topics was one central theme: the ongoing changes at the NRC. With massively shortened timelines, the ADVANCE Act and Executive Order 14300, and new interagency collaboration and authorization pathways in mind, speakers spent much of the RIC exploring what the road ahead looks like for the NRC.

Three-dimensional (3-D) computed micro X-ray tomography (micro CT) and 3-D confocal micro X-ray fluorescence (MXRF) combined are very useful nondestructive metrology techniques for determining the unique compositional and morphological information of fusion targets and target materials. Micro CT and confocal MXRF are being used in concert to examine a beryllium ablator capsule that has been sputtered and graded doped with copper and argon. In this manuscript, we will show that two-dimensional (2-D) MXRF imaging in concert with a simple radiograph is very useful for approximating the copper and argon profiles in the x and y dimensions, but because of the lack of signal discrimination in the z direction, image "bleed" from the sample regions where the X-rays are out of focus is prevalent. Data collected using the micro CT and overlapped with the confocal MXRF data produce absorbance and elemental line profiles without the signal bleed. Overlapping the 3-D data from these techniques provides a more accurate picture of the composition of these capsules than 2-D nondestructive techniques.
