Solar requires sunlight so increased storms, tornadoes, hurricanes, hail, etc can damage them and cause them to be less effective.
Hydro requires water so increased draughts will cause them to be less effective.
Nuclear requires cooling water which can be harder to deal with.
My point is that if you are expecting extreme weather it is best to diversify. I am not saying that nuclear will be immune to everything, only that it provides an alternative which we shouldn't ignore.
The possibility of failure should be contextualized with data. Gen 3 reactors are statistically orders of magnitude safer than any other power source, per GWh produced. Demonstrating how they are extremely safer than any other energy source.

> (for example a large wave hitting Japan) is much worse.
Mmh, like the 0-1 victims of Fukushima?
Nuclear power plants, just with Fukushima have demonstrated their tremendous reliability. We're talking about a 60-year-old reactor, which in the face of extreme conditions managed to minimize any kind of harm to humans.
