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.

As part of the development of technical bases which support the extended storage and transportation of used nuclear fuel, Pacific Northwest National Laboratory (PNNL) has implemented detailed thermal analysis methods for the calculation of best estimate temperatures of Dry Cask Storage (DCS) systems. These methods were used to model a NAC International MAGNASTOR® cask located at the Catawba Nuclear Station (Catawba) which is operated by Duke Energy This cask has one of the highest total heat loads of any DCS system loaded in the U.S.. Using best estimate operational data from the utility, fuel assembly and cask design information from the vendors, and decay heat estimates from Oak Ridge National Laboratory (ORNL), PNNL calculated the maximum cladding temperature of 307?C. This is well below the 400?C regulatory guidance limit.
