If I understand correctly, tritium is the result of bombarding lithium with neutrons. I'm not sure how tokomaks are expected to work; do you just add lithium and expect the tritium to get where it needs to go to keep the reaction going, or do you actively remove gases from vessel, filter out the tritium, and re-use it as fuel? Either way, I don't imagine it'd be too hard to recapture the stuff. https://en.wikipedia.org/wiki/Breeding_blanket https://en.wikipedia.org/wiki/Breeding_blanket
