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 neutron emission spectrum from the spontaneous fission of 252Cf has been measured for the 0.124- to 15.0-MeV energy range. In the measurement program, seven separate measurements were made of the spectrum between 7.0 and 15.0 MeV using a plastic scintillator as the neutron detector. For the 0.124- to 2.66-MeV energy range, a 6Li glass scintillator was used as the neutron detector. The data are presented with respect to a Maxwellian distribution with T = 1.42 MeV. Some positive and negative deviations with respect to this distribution have been observed.
