Pretty clearly shows why there’s no future for nuclear power.

Even for filling gaps in renewables, peaker plants are getting cheaper and don’t take 15 years to build.

I think that’s too simplistic of a view. Part of the high cost of nuclear is because of the somewhat niche use. As with everything, economies of scale makes things cheaper. Supporting one nuclear plant with specialized labor, parts, fuel, etc is much more expensive then supporting 100 plants, per Watt.

I can’t say more plants would drastically reduce costs. But it would definitely help.
