Part of the US response to the Fukushima event: earthquake + tsunami, US plants have been required to make provisions to address them.

Their standby diesel generator buildings have been fitted with waterproof doors, their intakes and exhausts raised in elevations beyond historic 100 year flood levels, and sites have been required to maintain portable pumps for flexible cooling solutions.

Of course all of this does not matter for Gen 3+ designs like the AP1000, which does not require circulating water to rid decay heat after an unplanned reactor trip. Those plants passively cool themselves.

The general publics knowledge of nuclear energy is beyond bad, it is dangerously bad.
