Researchers demonstrate remote real-time adjustment of PUR-1 reactor
The remote, automatic, real-time adjustment of a research reactor’s power by a geographically distributed control system has been reported by researchers from Idaho National Laboratory, the Grainger College of Engineering at the University of Illinois–Urbana-Champaign, and Purdue University. The investigators first used an automatic adjustment “digital control loop” system to demonstrate remote adjustments of Purdue’s PUR-1 research reactor. They then applied a reinforcement learning model that simulates the interaction of physical forces inside the reactor, making the loop system more autonomous.
