Fusion fuel: where does it go after fusion occurs?

Helion explains that fusion fuel does not end its journey when fusion stops; it is recycled through a closed-loop system where exhaust is captured, analyzed, separated into useful components, and reinjected into the machine for continued operation. Fuel enters the machine, part of it fuses, the exhaust is captured, the valuable components are separated, and the usable fuel is prepared to go back in again.
