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.

Breeding ratios for clean near-thermal systems containing only U233 and moderator have been presented by Chernick and Moore (1). The present work treats Pu239 systems also and extends the results in both systems to take account of the effects of the higher isotopes and fission products. The extra absorption by these higher isotopes tends to depress the breeding ratio, but fission in U235 or Pu241 compensate for this, and the net effect, as will be seen, is an increase in breeding ratio for plutonium-fuelled systems.
