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.
