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.

Measurements have been made to determine the effect of mutual shielding on the resonance absorption of neutrons by tightly packed thorium oxide lattice pins. From these measurements, correction factors have been obtained for reducing the results of single-pin resonance integral measurements to the effective lattice values. A comparison of the experimental results with the predictions of the theory of Dancoff and Ginsburg is included.
