Where is the tritium supposed to come from?

[โ€“] terrific@lemmy.ml 6 points 5 days ago

This is a very good point since tritium is a very limited resource.

The hope is that it will be generated by the fusion reactor itself using tritium breeder blankets https://www.iter.org/machine/supporting-systems/tritium-breeding

Whether that will work remains to be seen.
