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 2200 m/sec neutron cross section for deuterium has been determined relative to that for 59Co by absolute counting of the 3H and 80Co produced by neutron irradiation. The result, expressed in terms of the 2200 m/sec cross section for 59Co in b, and of the tritium half-life in years, is (1.104 ± 0.014 × 10-3) [σ0(59Co)] [t1/2(3H)] mb. Assuming σ0(59Co) = 37.4 ± 0.3 b and t1/2(3H) = 12.262 ± 0.004 years, gives σ0 (D) = 0.506 ± 0.010 mb. The standard deviation of the mean value from 8 irradiations was ± 0.2%.
