Safe nuclear’s the answer.
And plants built on safe soil - not on cheap land on fault lines like Japan and California have done.
California’s only existing nuke power plant, PG&E’s Diablo Canyon, is close (or closest; there are other more distant fault lines “near” it) to a fault line discovered over 20 years after it went into service.
Its very difficult to find a nuke site anywhere in California thats not “close” to a fault by some definition or another. There are a lot of faults in CA. It gets worse when one has to find a site with available cooling water.
Its a very similar problem in Japan. Fukushima was wrecked by a tsunami from an earthquake originating in a rather distant offshore fault. By that standard Japan cannot have any nukes.
One is just going to have to design around that risk. And Diablo Canyon is so designed. If that armored, triple redundant design can’t pass muster, nothing will.
