The nuclear sites here already have redundant diesel generators in hardened buildings. Fuel tanks are also protected.

Those that have them will likely be asked to take another look and offer some form of analysis to show that they can handle the anticipated events. There was a big controversy in the 1970s about plants sited around the Great Lakes and the question of seiches. Quite a lot of work was done to show that this kind of event could be handled. Same with tornadoes for plants located inland. It is almost assured that offsite power is going to be lost. Primary containment had been shown to handle debris impact from tornadic winds, but some effort had to be made to assure that secondary structures likewise could manage it. In particular, switchgear and connections from the diesels to the safety buses.

Our fuel tanks are in concrete bunkers and truck mounted backup generators are offsite. At Cluster Fukushima, the diesel generator fuel tanks were mounted on open concrete pads and the truck mounted backup generators parked next to them.

Here comes the big wash and adios power to the pumps. Amazing incompetence by their safety engineers whom were also warned years ago to raise the sea wall 3 meters and never did.
