Nuclear power plants are supposed to be safe. Many nuclear power plants in the USA are built next to the ocean..
In addition, all of our "coastal" reactors (none are actually on the coast) are on the east or gulf coasts, which have very low tsunami risk factors.
Basically the LA reactors are in an unsafe area and should be scrapped, and there are a couple downriver of major dams that should also be reevaluated, safety-wise, but the vast majority of US reactors are very well situated.
