Moving several EDGs and support system a couple kilometers is a small task in comparison to the design, qualification, construction, and training associated with a new power reactor design.

There’s nothing very complicated about the EDG buses that supply safety-system components.

The cables from the diesel generators a couple of kilometers away could have been destroyed by the tsunami or another earthquake.

This isn’t relevant to the fact that upgrading safety and safety support systems is less costly and a smaller engineering task than designing a new reactor.

Upgrades to such systems, including flex interfaces, has occurred across the US fleet in the years following Fukushima, while exactly zero new reactors have been designed and built.

Sure, there are better designs for EDG siting and support system integration. This is completely besides the point. The point is, even moving the whole safety support system kilometers away is cheaper than designing a new reactor, which I think should be a pretty uncontroversial statement to engineers familiar with the complexity of license approval for power reactors.
