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.

An experimental test of several equivalence relations for effective resonance integrals is obtained from measurements of U238 resonance escape probability for lattices of the TRX critical facility, and measurements of the U238 resonance integrals of isolated rods of UO2 and uranium metal. The TRX lattices were H2O-moderated and composed of cylindrical, aluminum-clad fuel rods of slightly enriched uranium metal or UO2. The measurements are in agreement with two forms of equivalence among lattice and isolated rod resonance integrals for a given fuel composition. The equivalence between resonance integrals for fuel rods of different compositions (IT and UO2) does not appear to be as good.
