Investing in what comes next

The 2026 ANS Annual Conference, “Net Out and Power Up,” brought the nuclear community together in Denver at the end of May. Over four days at the Sheraton Denver, we heard from exceptional speakers on the most consequential questions facing our field; how fusion and fission can complement each other, how to meet surging electricity demand, and what it takes to sustain American nuclear leadership. The embedded topicals on nuclear fuels and materials and on fusion energy added real technical depth. It was exactly the kind of gathering that reminds us why this community is so remarkable.
That energy and commitment is precisely what I want to channel as I close out my term as president of the American Nuclear Society. Because sustaining it year after year, conference after conference, requires more than enthusiasm. It requires investment.

One Modeling Framework for Integrated Tasks (OMFIT) has been used to develop a consistent tool for interfacing with, mapping, visualizing, and fitting tokamak profile measurements. OMFIT is used to integrate the many diverse diagnostics on multiple tokamak devices into a regular data structure, consistently applying spatial and temporal treatments to each channel of data. Tokamak data are fundamentally time dependent and are treated so from the start, with front-loaded and logic-based manipulations such as filtering based on the identification of edge-localized modes (ELMs) that commonly scatter data. Fitting is general in its approach, and tailorable in its application in order to address physics constraints and handle the multiple spatial and temporal scales involved. Although community standard one-dimensional fitting is supported, including scale length–fitting and fitting polynomial-exponential blends to capture the H-mode pedestal, OMFITprofiles includes two-dimensional (2-D) fitting using bivariate splines or radial basis functions. These 2-D fits produce regular evolutions in time, removing jitter that has historically been smoothed ad hoc in transport applications. Profiles interface directly with a wide variety of models within the OMFIT framework, providing the inputs for TRANSP, kinetic-EFIT 2-D equilibrium, and GPEC three-dimensional equilibrium calculations. The OMFITprofiles tool’s rapid and comprehensive analysis of dynamic plasma profiles thus provides the critical link between raw tokamak data and simulations necessary for physics understanding.
