US scientists turn nuclear waste into fuel to power fusion energy experiments

SMRTR summary

Scientists have developed a molten-salt accelerator system that transforms nuclear waste into tritium for fusion energy experiments. Led by Terence Tarnowsky at Los Alamos National Laboratory, the system addresses the critical tritium shortage (less than 55 pounds exists globally) while repurposing radioactive waste. The technology offers safety advantages over traditional methods, as it can be switched on and off without relying on self-sustaining chain reactions.
