As I said, Finland is one of the worst locations for renewables. There, nuclear remains at least within spitting distance of being competitive.

But as I also said elsewhere in these comments, this just means Finland (and other nearby countries at high latitude and without good wind resources) will become energy ghettos. They will lose their energy intensive industries. You will not be able to compete in such industries with countries where solar seasonality is low and insolation is very high. This means your energy consumption per capita will be depressed. Can a nuclear industry survive powering a handful of such disadvantaged countries? Maybe they'll just import energy from elsewhere (hydrogen can be piped like natural gas; while it has less energy per unit volume it also has considerably lower viscosity, reducing pumping costs.)
