In practice, people didn't flood the reactor, even when they needed to.
There's no way around this. People. Screw. Up.
But screwing up a wind turbine kills only the guy maintaining it. Screwing up a dam kills the people downstream. (Build it downstream from THEM, then.) Screwing up a solar plant... if it's thermal? Maybe breaks the molten salt container or something, but I'm guessing that's something someone can notice in time to jump out of the way. If not, it's still not as bad as a nuclear meltdown.
Meltdowns dont normally kill people, though, not anymore. They just happen to irreparably irradiate the land for a few hundred years or so, but that is not a problem if built in the right place.
You seriously underestimate the damage done by a nuclear accident. Radiations travel. remember the exclusion zone of Tchernobyl ? Well that's bullshit. Nuclear pollution can be found all round the plant, far away from the exclusion zone. Thousands of people have had thyroid cancer in Europe after Tchernobyl. Fukushima is still polluting the waters of the Pacific.
Meltdowns absolutely kill people, just not directly.
And placing nuclear reactors is still a problem, especially in high-density countries. You want them as far away as possible from the cities, fine. But where, then ? Uninhabited areas in western countries are usually next or inside natural parks and such, and no one will ever put a nuclear plant near a natural park. Out at sea ? Have fun if your waters are contaminated because radiation will absolutely spread.
The main problem with nuclear fission is that's it dangerous but more importantly expensive and not flexible. Nuclear fission represents less than 10% of the world's energy production. There's only one country that primarily uses nuclear fission as its main energy source and it's France, and this country is wandering what the hell it's gonna do when its plants become obsolete. We don't know how to safely and completely dismantle a plant, we simply don't. Nuclear plants are huge, expensive things. The new EPR reactor in France has already cost more than 10 billion dollars (that's the price of a full aircraft carrier and its accompanying fleet for god's sake !) and is 7 years behind schedule, despite being built by a company that builds nuclear plants since 40 years. Then there's the problem of uranium supply.
Nuclear plants are extremely complicated technical objects that cost an enormous amount of money, are less and less easily accepted in the public opinion and, if you're not a developed country, makes you rely entirely on foreign technology and companies. I don't see how nuclear fission could become more than the niche energy source it is today.
