They can improve seawalls and such, actually. And we can improve search & rescue operations.

Those don't protect from radiation very well, they're to prevent contamination. It takes several inches of lead to block gamma rays (you'd have to be Superman to move in a suit that heavy) and neutrons can activate otherwise non-radioactive elements. Alpha & beta radiation are relatively easy to block, though, but normal clothing is almost enough.
Also, it's just good engineering to take precautions. Also, near the plant, there actually are hazardous levels of radiation, it's just once you get further away that they're mostly harmless.
> And by the way, so far I have not heard a figure > 20000 for the number of the Tsunami victims, so I think you exaggerate with "tens of thousands" (it's horrible, nevertheless - but don't play the same tricks you accuse the anti nuclear media of).
I have, but who knows with the news? I've heard radiation figures from "100x normal" to "1,000,000x normal" (the LA Times had a much larger multiplier than the other papers I compared it to).
Also, remember the tsunami in the Indian ocean? Last I heard, the deaths there were on the order of 100k, if memory serves. Japan did what? 1/10th or so of that (again, depending on which numbers you believe).
I do not and cannot blame you for the media's hysteria, I'm just trying to help you not get caught up in it and to understand the real dangers that people are underestimating. Granted, you may not live in a coastal area, so you may not even have heard of seawalls before, but non-newsworthy things like improving them can save a lot of people.
But those kinds of projects will get starved for funding. So we'll end up with a lot of panicked people in California who shoot down new nuke plants in favor of coal/natural gas (the coal miners who die are in China, so there are no political consequences) and underestimate things like seawalls. California is said to be overdue for a big quake, but I hope they're wrong about that.
