Onyma, those links are great, informative and .... totally irrelevant in this case.

Never in the history of nuclear energy production has a 40yr old facility been forced to deal with the effects of a 9.0 earthquake, much less one quickly followed by a horrendous tsunami.

The facility lost its power, its emergency power which means they also lost control of necessary cooling functions for the reactors which has led to what they are seeing today: failure of the secondary containment structures, possible failures of one or more of the primary containment structures and melt downs of not just one, but multiple reactors and the loss/failure of every piece of equipment necessary to even monitor what's goin on in the reactor cores!

We have yet to see, much less know, what will be the real outcome in terms of nuclear contamination, radiation sickness on the population and surrounding area, so the jury is still out, not even mentioning the all too obvious reality which is they don't even have the situation under control yet.

Basing the possible outcome of what could occur in this instance on data regarding plants that never had to face this awful set of circumstances is totally irrelevant
