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 electron recoil spectra from gamma rays produced by the interaction of 14-MeV neutrons with 0.5, 1.0, 3.0, and 7.0 mean-free-paths (mfps) of nitrogen have been measured with NE-213 scintillators positioned at 26, 30, and 120 deg at distances ranging between 7 and 10 m. Thin wall spherical Dewars filled with liquid nitrogen, with radii dimensions equivalent to the above number of mfp, were bombarded with a centered nominal 14-MeV neutron source. Calculations of the gamma and recoil electron spectra have been carried out with the ENDF/B-IV and ENDL neutron-gamma libraries. Comparison between the measured and calculated electron recoil spectra shows that the discrepancies are not larger than 10%. This agreement implies that the calculated gamma-ray spectra are expected to give a good description of the gamma transport in nitrogen from a 14-MeV neutron source.
