And it wouldn't be a (small) fraction of the cost of a DT fusion power plant. The NSS, nuclear steam supply system, is estimated by the following link to be 12% of the cost of a NPP. https://world-nuclear.org/information-library/economic-aspects/economics-of-nuclear-power https://world-nuclear.org/information-library/economic-aspec... So, a fusion reactor an order of magnitude more expensive would double the cost of the entire power plant.

Again that would be more relevant if that was the only fission specific cost. That giant concrete building designed to survive an aircraft strike etc isn’t cheap. The equipment for handling spent fuel including the cooling pond and safety systems is more expensive than the reactor. Fuel rods end up 0.6c/kWh and on top of that requires weeks of downtime for refueling etc. People hear nuclear reactor and think that’s the most expensive bit, but it’s really not. I personally doubt fusion will be cost effective vs renewables + storage, but there’s reasons to suspect it could beat fission at scale.
