You can't provide some protection from storm surges and tsunamis and remain accessible to waterships.

Assuming the breakwater is a temporary obstacle that could be removed, and there's no spent fuel in that pool - if that even makes a difference at this point - I make that a distance of around 200m. Which doesn't sound totally impractical.

There's also the advantage of at least some cover from the turbine buildings.
