PPPL develops framework for unifying tokamak ML control models
Princeton Plasma Physics Laboratory announced that researchers at the lab, in collaboration with Princeton University, have developed a general algorithm for prediction and control in tokamak systems and have tested it at DIII-D, as presented in a recent Nuclear Fusion paper.
According to the paper, most machine learning (ML)–based tools for use in fusion machines have been implemented as stand-alone demonstrations, aiming to predict the plasma profile, suppress a form of instability, for example. PPPL’s project provides a framework that aims to accommodate these disparate models into an integrated system, which the team calls PACMAN (Prediction and Control Using Machine Learning).

As nuclear plants extend operation and pursue modernization, safety I&C upgrades increasingly require decisions between maintaining or enhancing existing analog (hardwired) systems and adopting qualified digital platforms. Each approach offers distinct technical, operational, and project execution considerations, and utilities must evaluate trade-offs that affect lifecycle support, room and cabinet utilization, wiring complexity, licensing effort, and long-term sustainability.
This webinar provides a clear, practical comparison of analog and digital safety I&C upgrade paths. The session will outline where hardwired architectures remain effective and straightforward to maintain, and where they introduce limitations such as dense copper cabling, footprint constraints, obsolescence risks, and increasing maintenance overhead. In parallel, we will examine modern digital options—with proven global operating experience—that streamline wiring through fiber-based architectures, reduce space requirements, simplify safety logic implementation, and support long-term evolution using standardized platforms and unified engineering environments.
Participants will gain a balanced understanding of:
By presenting the strengths and challenges of both analog and digital solutions, this webinar equips utilities, engineers, and project stakeholders with clear decision-making insight for near term upgrades and long-term modernization planning.
