Another problem with going fully nuclear: society is going to be highly dependent on basically a hand full of reactors so it's not that easy to shut them down in case unexpected defects are found or if they simply get too old without newer ones being built in time. We see this e.g. in France which largely runs on nuclear power: they still operate some old reactors with serious known issues. There also were some winters in the recent years where their grid was close to a blackout because a substantial part of the nuclear plants where in maintenance mode and electrical heating is widely used. It is only possible to prevent this because neighboring countries like Germany are able to reliably produce a lot of excess electricity (still too much coal unfortunately, thanks Merkel :() which they can import.
