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.

PURNIMA, a PuO2-fueled copper-reflected zero-energy fast reactor at Trombay, was built as a mockup of the proposed air-cooled 30-kW Kalpakkam Pulsed Fast Reactor. This paper describes the salient features of PURNIMA and discusses the calculational methods used and the control philosophy and operational procedures adopted. Important aspects relating to the overall safety are examined in detail. Some of the experiments carried out with this facility are also briefly reported.
