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 equilibrium phase diagram of the plutonium-cerium-copper system is presented, based on data obtained by differential thermal analysis, metallography and electron-microprobe x-ray analysis. Liquid-solid phase transitions were found between 419 and 1083°C. Ten crystalline phases solidify as primary phases from molten plutonium-cerium-copper solutions. No ternary compounds occur in the system. The ternary system is divided into two subsystems by the quasibinary section, CeCu2-PuCu2. Continuous solid solubility occurs along this join with neither a maximum nor a minimum. Solid solubility also occurs between the congruent compound, CeCu6, and the incongruent compound, Pu2Cu11. The ternary system is characterized by a single eutectic (4at.%Pu-68at.%Ce-28at.%Cu at 419°C), four peritectics, and two inversion points.
