Abstract

The Calutron, historically defined by the massive energy requirements of the Manhattan Project, has long been considered an inefficient relic of early nuclear physics. However, the emergence of High-Temperature Superconductors (HTS) and Inductively Coupled Plasma (ICP) sources necessitates a re-evaluation of electromagnetic separation (EMS) for modern isotope production. This paper investigates the optimization of a “Super-Calutron” facility designed to harvest high-value medical and industrial isotopes—specifically Lutetium-177 and Rhenium-187—from the activated powdered alloys diverted from Tokamak first-wall components. Using a 23 Full Factorial Design of Experiments (DoE), we performed a sensitivity analysis on three critical parameters: Plasma Power, Extraction Bias, and Magnetic Flux. Our results demonstrate that the transition to superconducting magnets reduces the energy-to-yield ratio by over 95% compared to 1940s baselines, while AI-stabilized ion steering achieves an isotopic purity of > 99.9%. The study identifies a critical “Double Ionization Threshold” at plasma power levels exceeding 2.0 kW, which serves as the primary constraint on throughput versus purity. We conclude that a modern MI-EMS (Multi-Isotope Electromagnetic Separation) facility, integrated into the byproduct cycle of a fusion powerplant, transforms a radioactive decommissioning liability into a strategic resource for nuclear medicine and aerospace superalloys. This research provides a scalable framework for a circular nuclear economy, turning “reactor dust” into the most precious materials on Earth.
