I think there's a difference between the theoretical worst-case scenario and the realistic worst-case scenario. A one-two punch of the largest recorded earthquake on record followed by a tsunami feels pretty close to realistic worst-case scenario. We can always fret and wring our hands about plausible issues, but we also need to recognize the cost of inaction as well. The risk of catastrophic meltdowns costing millions of lives is so small it's hardly worth factoring into a cost-benefit equation at all.
