Or what the consequences are for the reactor unit, the company and the world at large.... Well, instead of just doing an LW and saying I'm wrong, why don't YOU explain it & the consequences, for the reactor unit, the company and the world at large? And then, we can compare your explanations, to reality & what other "experts" are saying? Ok, in the case of a partial, or even a complete core melt the consequence for the Reactor unit is that it becomes unusable.......that's it... For the company--- They lose a lot of money due to having to build another reactor and decommission the old one (finish the shut down then either clean out and demolish, or clean out and seal up the old one) For the world at large- (without any containment and RPV breaches) ZERO (except some people might have problems with blackouts, if there's insufficent replacement electricity available nearby).... There you go Absolutely amazing! You truly are, blinded by something! Why, because you have taken NO REGARD of the outcomes of previous events, in particular links that you actually posted, on the outcomes of the Chernobyl event, nor have you taken any regard of what many other experts have written & discussed, on this Japanese event, in respect of the ramifications for people, nor the Economic ramifications! As for the company, besides that some of the senior should be indicted & sent to goal for a long time, they will be essentially bankrupt and the government will most likely have to prop them up, in some way shape or form, with Public money! As for the world, the entire Japanese Tri-fecta (earthquake, Tsunami & Nuclear problem, will likely cost the world Economy something around 2-3% of GDP (around $60-65 Trillion) over the next 3-5 years. But, you knew all of this, it's already out there, for people who don't have fixed minds! That said, I still think we will have to have Nuclear as part of the Energy mix, over the next 100 years or so, as we move away from Fossil Fuels. Following are just 2 posts I have put up, specifically where are they incorrect - Nuclear meltdown A nuclear meltdown is a severe nuclear reactor accident that results in core damage from overheating.The term is not officially defined by the International Atomic Energy Agency[1] or by the U.S. Nuclear Regulatory Commission.[2] However, it has been defined to mean the accidental melting of the core of a nuclear reactor,[3] and is in common usage a reference to the core's either complete or partial collapse. "Core melt accident" and "partial core melt"[4] are the analogous technical terms.A core melt accident occurs when the heat generated by a nuclear reactor exceeds the heat removed by the cooling systems to the point where at least one nuclear fuel element exceeds its melting point. A meltdown may be caused by a loss of coolant, loss of coolant pressure, or low coolant flow rate or be the result of a criticality excursion in which the reactor is operated at a power level that exceeds its .http://en.wikipedia.org/wiki/Nuclear_meltdown Meltdown fears at Fukushima, radiation spreads As dangerously high levels of radiation spread beyond the Fukushima exclusion zone in Japan, there are fears the race to contain the nuclear crisis has been lost and meltdown has already taken place.
Richard Lahey, head of safety research for this type of reactor at General Electric, which installed the reactors at Fukushima in the 1970s, says workers at the site appear to have lost the race to save the crippled No. 2 reactor.
The Guardian newspaper quotes him as saying he believes the reactor core has melted through the bottom of the pressure vessel and at least some of it is down on the concrete floor beneath.
This would mean in simple terms the accident is no longer a matter of melting fuel rods, but of meltdown. http://www.abc.net.au/news/stories/2011/03/31/3178263.htm=============== There are a many reports of a partial meltdown already and the Japanese government & the owners of the Fuku plant aren't running around like headless chooks, for no good reason, they are trying to prevent a full meltdown or another full meltdown. First off..Chernobyl was a Reactor EXPLOSION, not a Reactor meltdown, so the two cases are entirely DISsimilar.... And secondly, while the c&p'd info is partial accurate, the definition of meltdon is correct, the Guardian's stuff about the material melting through the RPV is, at best, a misquote, and at worst, a complete load of bovine fecal matter.... where did the Plutonium in the soil come from?
