Multiple cooling system failures at multiple plants (backup batteries as well as main water pumps power failed), one containment structure blown up, two probable meltdowns (they can't tell for sure because they can't get inside, but have presumed them to be meltdowns), at least 6 plants in trouble, radiation leak at one plant, evacuation of about 200,000 people, and last-resort measures being taken at at least two plants (pumping in of sea water). Radiation 700 x normal 60 miles from its source (Fukushima 1 reactor). Further, we have no reason to trust "authorities" in this situation and much reason to distrust them, and to suspect that current conditions and potential peril are worse than they are portraying them.
We should be concerned about impacts on human life and sea life around the Pacific from what has happened so far (for instance, what is being done with the volumes of sea water that are being dumped on these reactors?), and all countries downstream and downwind of Japan should have declared a state of emergency until it has been established and VERIFIED that these nuclear plants are contained.
Japan is known for being the best country in the world as to earthquake and tsunami preparedness and also safety features in their nuke plants--so that is the "good news." The bad news is that it looks like at least six cooling systems failed, in already disastrous conditions as to infrastructure (making nuke plant response even more difficult). They may have already made a mistake (trying to blow off steam may have caused the explosion of the secondary containment structure in F-1--but I'm not sure if that was an automatic system). In any case, the stress on officials and workers trying to deal with this must be off the charts. Very, very difficult situation. This was the worst earthquake in Japan's recorded history with huge following damage from the tsunami (tsunami hit the nuke plants as well). Criminy, this earthquake moved the island of Japan 8 feet! One aftershock was a 6.7! An aftershock! (And we don't know that the tremors are over.)
So, whatever one thinks of the OP map (and, frankly, whenever someone tells me that something has been "debunked," I always give it a second look), this is not a time to be debunking the danger of this situation in Japan. It is very dangerous.
You wrote: "The chances of the plant actually blowing and destroying the containment system is not very high."
It's not just one plant--it's at least six. And the containment structure over one already blew up (but apparently not the inner steel containment over the core). Nuclear material was released at this one (F-1). That has been admitted. You speak of "chances." Well, the "chances" have already been breached, with a 9.0 earthquake and following tsunami. The question is, can they keep this meltdown stopped (by pouring sea water on it)? They may have a second meltdown (it has been presumed). Can they keep that one cooled with sea water, too? And they are having cooling system failures at other plants. The "chances" of me dying in a car crash are remote, statistically. Should I not bother with my seatbelt then? We're talking a BIG BOOM-BOOM here, if "the chances" go bad. This is not something to demean, downplay or ridicule.
You wrote: "Even if a meltdown occurs there is a still a containment system in place."
Outer containment failed at one. Some radiation released (and apparently traveled at least 60 miles). Infrastructure conditions are very difficult, not only generally, but also at the plants--gauges not working, backup battery systems not working, plant too "hot" to get into, etc. There WERE containment systems in place--not "are"--were. Critical parts of them are down. That is the problem. And it is, of course, the problem generally with nuclear energy. Events like this earthquake--rare though they may be--if they impact such facilities, don't just result in loss of the facilities but could result in turning Japan and portions of the Pacific into a wasteland. The "chances" may be slight (although from the reports so far, these are not slight), but the catastrophe, if it occurs, is armageddon-like. There is no recovery. You cannot rebuild an irradiated wasteland.
The earth and its oceans only have so much ability to absorb our shit. We really need to recognize this. If the worst happens in Japan, we could be looking at the end of the earth. Carl Sagan, in his book "The Cold and the Dark," established that only a limited exchange of nuclear weapons would kill all life on earth in a matter of months. The worst case scenario probably won't happen in Japan, but if it does--and it can-- that is a possibility--out of control meltdown in multiple reactors, though it wouldn't create dust clouds, could well create winds and wet clouds of nuclear radiation circling the earth, with devastating impacts, if not total collapse of earth's ecosystem--will you still have this smug attitude about "hysteria"?
It is NOT "hysteria" to be concerned about this. It really and truly is not. There are many possible scenarios, from continual low level leakage up to world catastrophe, that are possibilities in this particular situation, and that should be included in all considerations of the use of nuclear energy (as well as in the possession and proliferation of nuclear weapons). The "worst case scenarios" are simply too heavy to brush aside as to their "chances" of happening and even "minor" failures in nuclear power systems and "limited" use of nuclear weapons have long term consequences for the people and ecosystems that are affected and possibly far beyond that.
As to coal vs. nuclear power--if you want to talk about "chances": At least with coal, we have a chance to clean up our act. With a multiple nuclear power meltdown, or a nuclear war, we don't. Big difference. I don't favor coal. I think we should put all the resources we are now wasting on war (including the "war on drugs")--trillions of dollars, all told--into fast conversion to all the alternatives. But coal/climate change is the argument now being used by the nuclear industry to sell its product. Even coal--bad as it is--is better than nuke plants, because the "worst case" scenarios with nuke plants are so very, very bad and so very, very permanent.
