If it were just about the money, then nuclear would not be very attractive.
But it's the environment, stupid. Compared to fossil fuels, nuclear is an attractive option, cost be damned. Hydro is not without detriment. Solar uses space. Wind is going to be seen as a loser in so many ways, but it is a stepping stone.
Nuclear is the best option, and SMR among other technologies will improve the option.
ps - Previous comment about desalination in higher latitudes might, I think, miss the basic equation. Fresh water is more readily available at higher latitudes than lower, until you get into the ice. Nuclear powering desalination in Southern California, yes. Alaska? Dude?
