There are places where solar is less than helpful -- up here in Scotland, we're north of Moscow: in midwinter we get as little as 4.5 hours of daylight every 24 hours (6 hours here in Edinburgh, in the south). Also, we tend to live in apartment buildings: many dwellings, only one roof, shared gardens.

(On the flip side, we're in one of the world's best areas for wind and tidal power.)

The point is, the far north (think Scandinavia, Russia, the UK) really needs non-solar. And the far-far north is a lousy environment to go out and fix a broken wind turbine. So there's probably a role for nuclear there.

There may also be a role for nuclear in shipping, although civil nuclear shipping peaked early (in the 1950s/60s) and the only folks currently doing much of it are the military and the Russian arctic icebreaker fleet. If oil becomes too expensive for propulsion, nuclear may be necessary as backup for wind power (sails and weather satellites work great together -- until you're becalmed).

Sweden in 2014 produced about 64 TWh (42%) from large hydro and 62 TWh (41%) from nuclear. The rest came from wind 12 TWh (7.9%) and from other 13 TWh (8.5%)! other being mostly biofuel and waste.

The interesting thing here is probably the change over time. In 2005 the distribution was 72 TWh (hydro), 70 TWh (nuclear), 0.9 TWh (wind), 12 TWh (other). With wind growing by 13x and the others staying relatively static, and energy use going down slightly. [1] There is quite a lot of variance per year, as the winter weather changes energy consumption quite significantly.

Electricity export has gone from about zero (2005-2007) to 15 TWh (2012-2014).
