The fix to me is to build reactors in locations not liable to tsunami damage. Fukushima survived the 9.0 magnitude earthquake with serious but Manageable damage, it was the wave that did it in. We’ve got to learn to safely build and run nuclear plants.
Why don’t they build incinerators to burn all the junk that has floated away.......
We already know how to do that. It's just that governments make it so hard to build new plants that energy producers are forced to keep outdated plants online for decades longer than intended.
