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 attenuation of fast neutrons by long, thin air ducts in shields is considered from a simple phenomenological point of view. It is shown that the wall-scattered flux in a straight duct is small compared to the uncollided neutrons which travel directly in air from one end of the duct to the other. An expression for the attenuation due to a bend is derived and this is generalized to the case of several bends.
