Jefferson Lab $29M DOE Spin-Polarized Fusion Fuel Project Highlighted by NPR

On May 14, 2026, NPR affiliates WHRO (Hampton Roads) and VPM (Richmond) highlighted Jefferson Lab's active DOE-funded research into spin-polarized deuterium-tritium fusion fuel — a $29 million programme led by physicist Xiangdong Wei. The technique aligns the nuclear spin states of D-T fuel nuclei to preferentially increase the fusion cross-section, with theoretical models suggesting yield efficiency gains of up to 80% at equivalent plasma conditions. If validated at scale, spin-polarized fuel could significantly lower the plasma performance threshold required for net energy gain and commercial operation. The enriched fuel will ultimately be tested at the DIII-D National Fusion Facility (San Diego, CA) in a multi-institution collaboration including the University of Virginia and DOE national laboratories.
