Use carbon for the inner wall. It is relatively cheap, neutron addition to C12 turns it into C13 which is stable, it can withstand high temperatures, and will act as a neutron moderator, slowing the neutrons so that they may be more easily captured by the next Li layer needed to produce T. An alternative is Be which will act as a neutron multiplier, thus making the production of T easier. [snip] Regards, Robin van Spaandonk local asymmetry = temporary success
