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 new approach to modeling fissile solution densities is developed and applied to arbitrary solutions of UO22+, Th4+, Pu4+, H+, and NO3- in water. The model is based on the semiempirical method of Pitzer for describing electrolyte solution thermodynamics. This new density model has been included in the recent release of the SCALE 5 code system as the default for criticality calculations of fissile solutions.
