Pretty well all nuclear power stations are situated close to the sea, which is intrinsically dangerous. Even in places where tsunami are not anticipated, rises in sea level can be expected, and seasonal flooding.

Talk about nuclear power providing a quick solution while renewable power is a long way off are in fact the reverse of the truth, so far as fresh nuclear power is concerned.Nuclear power stations take a long time to commission and construct, renewable technologies are advancing fast, even without the input that could advance them a lot faster. It may be possible to defend existing nuclear power planr, on the grounds that they are providing power at this point, and decomissioning them is an enormous problem, but that's a different story. And we are still far far away from any answer to the prblem of longterm waste, liable to be lethal for tens of thousands of years.

Conceivably in time fusion power plants might be viable - but the most important source of energy long term is going to be the enormous fusion plant we've already got a a safe distance off, the Sun, providing us with solar power, and indirectly water and wind power. Supplement that with tidal power, thanks to the Moon, and in some places thermal energy power from within the Earth. There's really no shortage of available pwer there for the taking.
