Biggest cost factors for current nuclear isn't steel, nor labor. It's interest, especially when the project takes 20y instead pf 4-6/unit with several built in parallel
The cost of interest depends both on cost of materials and duration. A plant that takes 20y to build will cost much more vs a plant that's done in 6y. If we relearn to build fast(er) nuclear will get cheap enough to get a place on the grid
