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.

The four-factor critical equation for a heterogeneous thermal reactor is looked at in detail. It is then written in terms of parameters which characterize separately the fuel element, the moderator, and the lattice cell geometry of a heterogeneous thermal reactor. Methods for determining the parameters are then discussed. The results of measurements and analysis for two different fuel element types are compared with the results of measurements made on full lattices consisting of these fuel elements.
