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.

In this overview, the main arguments for a kinetic description of a classical non-relativistic many particle system are reviewed. First, the need and strategy for a kinetic description of plasma particles is discussed. The Vlasov, the Landau-Fokker-Planck, and the Balescu-Lenard equations are presented as the most useful kinetic equations for the particle distribution functions. It is shown that a linearization of the initial value problem can already give interesting insights into the dynamic behaviors. In many cases a reduction to a plasmadynamic (fluid) description is appropriate, and popular truncations are summarized. Finally, the basic methods for a kinetic description of waves are presented. When some wave excitations are driven unstable and the collective motion of particles dominates, the wave-kinetic equations will be the appropriate dynamical equations. It is shown that spectra of the Kolmogorov-Obukhov type are exact stationary solutions of the latter.
