The point is that Fukushima's location isn't very good. Ocean cooling might be easier, but finding another cooling solution is a better answer than risking a tsunami. It's unclear whether we knew that before or after the disaster. As for sea walls, I don't think they work - Tsunamis wrap around whole islands, I'm reasonably sure the generators would have been useless with or without a seawall.
I get that Fukushima isn't as bad as Chernobyl, but you can't look at the damage it has caused and say that everything worked as intended, or that this was an acceptable risk. There's a lot more to worry about from Fukushima than just medical problems, including serious economic disruption. There is a 12 mile exclusion zone - how many people have been displaced, and how long before they can return. What's the clean up cost? And probably most significant, there is the social impact - I'm all for education, and actual information on the scope of the medical risk from this radiation release can only be helpful, but if you ever want to see another nuclear power plant built in your lifetime, the message can't be that the disaster wasn't that bad, so we don't need to take any remedial actions. And for whatever reason, people just won't believe you if you tell them that the above-background Cs-137 in their spinach isn't a health risk - I don't care how many toxicological studies you have.
We have to take something away from this, people in policy positions need to be communicating that this won't happen again. From what I've read, the most sensible thing to do is explain that Fukushima was struck by two disasters, either of which it could have withstood, but together overwhelmed the safeguards. Therefore, now that we've recognized this failure mode, we are taking safeguards to prevent it from happening again. That means (1) designing/retrofitting reactors in seismic areas to withstand 9.0 magnitude quakes, (2) not building reactors in areas that can be struck by both large magnitude quakes and tsunamis, and (3) changing SOP so that if the reactor needs to be vented, it will be vented directly into the atmosphere and not into the containment building (and explaining that the N-13 that spiked the radiation detector is of no risk to anyone who isn't sitting on top of the vent pipe.)
