#i've been following the nuclear side pretty much all day every day this week via a thread on another forum with quite a few Japanese posters and its been quite a ride and i'm sitting in london =/
What has truly appaled me is the utter ratings chasing that is going on from most of the press. Reporting either wrong information, or exagerated information, or general misinformation which in no way helps anyone but just scares them unnecessarily.
What has been readily apparent is that a massive amount of people are worried who have no idea a) how a nuclear power station functions, b) what actually happened at Chernobyl, c) why this is totally different from Chernobyl and to top it off d) they are trusting some of the most ridiculous news sources going because they seem to think that all news = 100% truth. So few seem inclined to educate themselves
My continuing fear is that this entire event, even if it gets resolved and there is no major radiation problems and no superheroes emerge or anything like that, stops production of new plants in western nations. I honestly don't think that can be allowed to happen.
The accident is totally different to Chernobyl, the outcome SO FAR is quite different, the potential worst case scenario, shouldn't be as bad, but the actual, real worst case scenario isn't far off.
With Chernobyl a lot of stuff was spewed a very long way, most of that didn't actually do all that much, upset some Boar in Germany and some sheep in Wales, and some farmers standing behind the sheep, in reality the most damage was very local to Chernobyl, theres a fairly real chance of significant local damage from these plants, the worst case isn't miles off.
One of the biggest reasons people have been saying this "can't be a chernobyl" is because Chernobyl didn't have a containment building and these do, hate to tell you but the majority of radiation at the moment is being spewed out directly from WITHIN the containment building that people are talking about making this totally different. 2 of the containment buildings are severely damaged, a 3rd is severely damaged but no signs the pool is open to the air, though it might be.
Theres a very real chance, listed as a fear in the official status report that the open to air spent fuel rods in plant 4 could reach critical reactivity and start the chain reaction again, they've had one day long fire in there already, couple that + a fire spewing radiation into the air and you actually have something VERY close to Chernobyl, its not particularly likely to happen, theres still a decent chance it could.
The reactors themselves look safer, while they are hot and partial meltdown is almost certain to have occured in 3 of them, they are getting water continuously at the moment, they are venting the lightly radioactive steam from that cooling but thats magnitudes less bad than the cores going into full meltdown. Having cooling has already failed several times, bad situations in the other reactors has effected cooling around it, the explosion at 3 knocked out 4 of the 5 fire pumps they had for some time.
This isn't a small accident and it has potential to be huge, some media are saying like its almost a certainty, too many people are making completely false claims that this could NEVER be like Chernobyl and the danger is passed is another claim we've seen, both of those things are the LEAST accurate description of current events.
As for your continuing fear, get a grip and stop being naive, things wrong with these reactors, and most important the chain of events are INCREDIBLY important, if ANYTHING at all can be learnt and put into new reactors as increased safety measures then by all means new plants SHOULD be delayed and upgraded before they are built.
Will a reactor in germany suffer a Tsunami, bar an extinction level asteroid to an ocean, no, can back up generators on site get flooded in torrential rain, can power lines be knocked out requiring their immediate shut down, loss of primary cooling function and their backups run into trouble, yes, ANYTHING that leads to a safety increase would be worth the wait.
Frankly, as in EVERYTHING, history is the best teacher, mistakes at Chernobyl led to newer safety measures, same at Three Mile, this will to and unfortunately the next inevitable accident will also lead to improvements, thats how we've learned as the human race, through our mistakes.
Chernobyl, the problem is, as you said, misunderstood, it was very bad and yet, not very bad at all. The official death numbers are utter balls, the clean up crew of 600k people left 220k+ dead or disabled..... but ultimately years later its largely just a fairly overall quite small area of land left uninhabitable, in the grand scheme of things, its far from the worst disaster the world has ever seen, or will see. Its the worst nuclear accident and yet no where near the worst disaster in the world.
