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 fission product spectra in discharged fuel from fast fission power reactors have been calculated over a wide range of operating conditions (reactor operating times from 10 to 10,000 days and cooling times from zero to infinity). These calculations are based on recent yield data for fission of uranium and plutonium. From these calculated data are presented derived data of total curies and energy dissipation rates as functions of operating time and cooling time.
