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 age of fission neutrons to indium-resonance energy has been measured in AGOT graphite using the point-source technique. Corrections to the data arising from the following factors were investigated: (a) source and foil size, (b) finite dimensions of medium, (c) higher- and/or lower-energy activations, and (d) angular sensitivity of detector foils. The age was determined to be 307.8 ± 1.9 cm2; the fourth and sixth moments were 6.58 ± 0.05 × 106 cm4 and 3.84 ± 0.06 × 1010 cm6, respectively. These agree well with the values of 307.4 ± 1.0 cm2, 6.59 ± 0.06 × 106 cm4, and 4.01 ± 0.09 × 1010 cm6 obtained by Monte Carlo calculations.
