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 values of the average number of prompt neutrons emitted in the spontaneous fission of some recently available even-even heavy nuclides have been determined by separately counting neutrons and spontaneous fissions and comparing these counts with similar counts from 252Cf standards. The results are as follows: 244Pu , 248Cm , 250Cm , 250Cf , 254Cf , all on the basis of for 252Cf. A comparison of these results with existing data for other heavy nuclides indicates that is both Z and A dependent in a manner similar to that calculated by Bondarenko et al.
