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 prompt fission neutron energy spectrum of 235 U was measured at an incident neutron energy of 0.40 MeV with two samples of different thickness. The data were corrected for flux attenuation in the sample material and for effects due to the energy change of the out-going fission neutrons by inelastic scattering and secondary fission processes. After applying these shape corrections, an average fission neutron energy of 2.06 ± 0.05 MeV was obtained using the Watt and the Maxwellian functions for the energy distribution of the fission neutrons. This result has been compared with the presently available results of other works.
