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.

Duplex coated fuel particles consist of two discontinuous layers of pyrolytic coating. Theoretical advantages of the layered construction appear substantiated in irradiation tests. The inner coating is applied at temperatures of 1400 C to 1750 C, and the high-density, more graphitic final coating is applied at 1800 to 2200 C. Coating micro-structure may be varied from a rough-surfaced highly oolitic conical pyrolytic to a smooth, glossy fine coned pyrolytic. The force necessary to crush these particles is inversely proportional to pyrolytic cone length. Irradiation of Duplex particles at temperatures up to 1200 C and bum-up s to 30 atom percent show a steady Kr88 of 10-5.
