AI at work: Southern Nuclear’s adoption of Copilot agents drives fleet forward
Southern Nuclear is leading the charge in artificial intelligence integration, with employee-developed applications driving efficiencies in maintenance, operations, safety, and performance.
The tools span all roles within the company, with thousands of documented uses throughout the fleet, including improved maintenance efficiency, risk awareness in maintenance activities, and better-informed decision-making. The data-intensive process of preparing for and executing maintenance operations is streamlined by leveraging AI to put the right information at the fingertips for maintenance leaders, planners, schedulers, engineers, and technicians.

Resonance absorption in heterogeneous media with intermediate-mass moderators is investigated under the assumption that the flux is spatially flat in each region. Intermediate resonance parameters are introduced for scattering by all species present in the system and an intermediate resonance approximation is developed for calculating them. An improved rational representation for the lump escape probability is used and the calculation of the Dancoff factor is modified to account for the intermediate nature of the scattering-removal process by the outside moderator. The resonance integrals from the intermediate resonance approximation are compared with those from Monte Carlo and ZUT computer code calculations for the 6.7-eV resonance of 238U. The intermediate-resonance approximation results are found to be in good agreement with the Monte Carlo results. The ZUT results have large errors for heavy moderators, especially in undermoderated systems. Equivalence among heterogeneous systems and between heterogeneous and homogeneous systems is discussed. In the former case, an equivalence through the intermediate parameters is established.
