This article has emphasised intrinsic concerns for commercial
fusion, the major points being:
• excessive cost compared to fission, because of enormous size
and complexity;
• low operational availability due to the necessity to frequently
replace components damaged by neutron irradiation;
• scarcity of tritium fuel, requiring regeneration in operations
and probably supplies for startup from a fleet of fission reactors.
• Questionable worldwide implimentation compared with fission reactors. [John Shanahan]
The answer to the question in the title of this paper, therefore, is that there is no reason to bother with fusion. It will almost certainly have no advantages over fission
