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 method for solving the neutron diffusion equations in multiconnected regions with arbitrarily shaped boundaries has been developed by using a compound boundary-fitted coordinate transformation. In the compound boundary-fitted coordinate transformation, inner regions and an outer region in the physical plane are transformed by different coordinate systems. The neutron diffusion equations obtained by the coordinate transformation are solved in the rectangular coordinate system for the outer region, and in the cylindrical coordinate system for the inner regions, so that the boundary conditions are represented accurately and detailed calculations in a particular region can be performed without increasing the number of grid points in other regions.
