Thank you. So do they need to source tritium externally at all? I’ve seen people claim CFS will have to source tritium, making it expensive to operate. Can they breed all they need?
- DennisP 5y agoThey'll need tritium for startup. After that they shouldn't need more if they can get the breeding ratio high enough, but that might not be easy.
- TaylorAlexander 5y agoInteresting thank you!

- ncmncm 5y agoIn practice it means the mix of Li-6 and Li-7 in your coolant pipes has to capture more than half of the neutrons emitted, and not too many of the slow neutrons released in intermediate reactions get stolen.
- pfdietz 5y agoUnless a DT reactor can breed its own tritium it will be totally economically hopeless.
- TaylorAlexander 5y agoYeah. Someone the other day said in a comment that commercial fusion will never be viable because tritium is so expensive. But it does sound like breeding is the plan at least with ARC so I don't know what that commenter was thinking.
