I'm highly skeptical that prices can remain low as that scales out to 10-40% of electric generation, given constraints on things like rare earth metals. There is also the issue of equipment wearing out relatively quickly compared to conventional/nuclear plants.
SMRs, built using mass production rather than one-off construction, and possessing safety qualities far beyond current reactors, will be necessary to provide safe, reliable, clean and cheap energy alongside "renewables", IMNSHO.
