At least three nuclear reactors in Japan are reported to have experienced partial meltdowns. But just what does "meltdown" mean?
Three decades ago, a film called "The China Syndrome" introduced many Americans to the possibility of a nuclear accident and the phrase "nuclear meltdown." Twelve days later, the Three Mile Island accident in Pennsylvania had federal officials discussing the real thing.
So just what is a nuclear meltdown? The reactor contains rods filled with uranium, and then there's a pump which sends coolants like water into the reactor, to keep the uranium from overheating.
When the pump breaks down (in this case because of the earthquake or tsunami), the uranium overheats. The rest of the water eventually boils away, and tubes holding the uranium pellets disintegrate. The pellets fall to the floor, heating up even more, up to 5,000 degrees, at which point they melt into kind of a waxy substance. Thus the term: "meltdown."
In the worst case scenario the uranium, already very unstable, explodes, damaging the plant and releasing contaminants into the air.
There can be a minor or major meltdown, depending on how many pellets melt. And even a major meltdown might pose no danger to the public at large, if there's no explosion and the radiation stays within the containment dome.
I am writing this text (Mar 12) to give you some peace of mind regarding some of the troubles in Japan, that is the safety of Japan's nuclear reactors. Up front, the situation is serious, but under control. And this text is long! But you will know more about nuclear power plants after reading it than all journalists on this planet put together.
There was and will *not* be any significant release of radioactivity.
By "significant" I mean a level of radiation of more than what you would receive on ' say ' a long distance flight, or drinking a glass of beer that comes from certain areas with high levels of natural background radiation.
I have been reading every news release on the incident since the earthquake. There has not been one single (!) report that was accurate and free of errors (and part of that problem is also a weakness in the Japanese crisis communication). By "not free of errors" I do not refer to tendentious anti-nuclear journalism ' that is quite normal these days. By "not free of errors" I mean blatant errors regarding physics and natural law, as well as gross misinterpretation of facts, due to an obvious lack of fundamental and basic understanding of the way nuclear reactors are build and operated. I have read a 3 page report on CNN where every single paragraph contained an error.
We will have to cover some fundamentals, before we get into what is going on.

Some 2012 predictions had mentioned about their appearance too.
Are you serious ? do you really believe such stuff ?
Is our Nuclear Power/Energy plants are Safe!!!!??
Nuclear Problem = I believe.
I hope there are adequate safety features in the Indian Nuclear Facility.Originally posted by: angie.4uJapan is prone to earthquakes and tsunamis due to its geographical location over 3 tectonic plates. Its govt is doing all it can under the grim circumstances. Delhi too falls under the high risk zone as far as earthquakes are considered. I would not even want to think what the govt would or could do in case of a disaster of this scale!
