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.

A comparison of local linear power densities measured with a gamma thermometer string (GTS) and with a fission chamber shows important discrepancies at the extremities of the assembly. The cause was revealed by a simulation of axial power distribution. These discrepancies appear to arise from inaccurate knowledge of the axial position of the GTS in the assembly. Using the method of fictitious displacement of a GTS, it was possible to reduce these discrepancies to <3.7%. One method of reducing this disadvantage could be to include the GTS in the fuel assemblies in the factory. By this way, it would be possible to eliminate passages for the string through the bottom of the core vessel.
