If someone falls off a ladder, life goes on for the rest of us.
If nuclear power plants have an accident like in Fukushima. then tens of thousands have lost their home for decades or forever and ten thousand workers will fight for three decades to clean up the mess under the worst possible circumstances with costs going into the hundred billion dollars.
In middle Europe easily a few million people can be affected.

Sure. But again, compare the area of land rendered uninhabitable - and the homes and lives lost - per megawatt generated. If you consider "renewables" as a whole then the area rendered uninhabitable by hydroelectric dams - even assuming they function perfectly - is much larger than for nuclear disasters. If you consider solar plus actually existing battery technology then you need to talk about the area blighted by rare earth mining etc. (Yes uranium mining is also pretty harmful, but again we need to talk about impact per megawatt). If you're considering solar on its own then you're never going to be able to provide reliable baseline power.
Nobody builds one where I live. But there are several nuclear power plants. But most of them are now history. They are not in some remote areas, but near populated areas with millions of people.

Why would I 'consider solar on its own' as baseline power? These arguments were brought up twenty years ago and were boring then. Even though there are solar power plants which store heat.
The biggest achievement of the Energiewende is that it has broken up the big electricity monopolies of the nuclear- and fossil-based electricity companies. It has enabled two decades of exciting research into new technologies and enabled distributed energy production by much smaller players. It's a paradigm shift like it was from few Mainframe computers to the distributed nature of the modern Internet.

This is a failure of planning (or possibly of international diplomacy in the case of e.g. Japan). In terms of the engineering constraints, nuclear plants are a lot easier to build far away from people than any of the alternatives: they don't have to be built on particular parts of rivers, or in a sunny or windy area, or a gas pipeline or an endless supply of mile-long coal trains. (They probably do have to be on some kind of rail line just because fuel transport is excessively regulated).

It may be boring, but the issues are still real. Baseline power is a requirement, and the only proven ways to provide it are carbon-based, hydro, or nuclear.

There was only ever one in full-scale production, and it's now closed, AIUI. There are various experimental efforts.
You need to revisit your facts. Solar plants with storage are currently in operation [1] [2]. They have been producing 370GWh per year. This is tiny compared to a mid-sized nuclear power plant, but the technology is there and is easy to scale up without hazards.
You will agree then that a 10kW residential solar installation on a roof is "experimental" and "not in full-scale production".
What about the 1 million residential solar installations done in 2016? Is that "experimental"? When you add 20 100MW plants, you reach the scale of a nuclear plant. That is precisely the beauty of solar. That it can grow incrementally without high capital costs (unlike borrowing $4bn and a huge insurance at once with nuclear).
Still carbon-based. Burning x tonnes of hydrocarbons is still burning x tonnes of hydrocarbons even if the carbon was only recently captured from the atmosphere - it's basically no different from burning coal and running a sequestration process in parallel. Carbon is fungible.
