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 properties of a classical stellarator will be described and the need to optimise stellarators will be motivated. The principles of optimisation will be presented. W7-AS, a partly optimised modular stellarator, will be briefly introduced and some results with relevance to its optimised properties will be summarised. The fully optimised large stellarator W7-X will be described and the progress in optimisation from W7-AS to W7-X will be discussed. The possible design of an optimised stellarator reactor will be presented.
