Arnold Gundersen On Fukushima Nuclear Radiation Update Part 2

http://www.emfnews.org/products.html Arnold Gundersen On Fukushima Nuclear Radiation Update Arnie Gundersen: The term is really old; it dates back at least until the 60's. And what it means is that the nuclear core melts, and of course it is an American term, so it melted from America toward China through the center of the earth. That is what the term means. It is an over-exaggeration to begin with, but it does mean that the nuclear core leaves the nuclear reactor, leaves the containment, and gets into the earth. That is what a China Syndrome really means. Now I will be using some rather crude demonstration items today. I realize a lot of engineers watch this and just bear with me here. I think these are analogies and they are always a little risky, but I do think they explain what is happening inside Fukushima.

The first phase of the accident was when the nuclear reactor core lost it's cooling. Now you will remember uranium atoms split; 95% of the power comes from uranium atoms splitting. But these pieces that are left over are called fission products, and they retain a lot of heat. When you shut a nuclear reactor down, a process that takes about 2 seconds, 95% of the heat stops immediately, but 5% of the heat cannot be stopped. That, as long as there is extra water flowing, is all you need to keep a nuclear reactor cool. You remember back in April, I did a video where I talked about a nuclear reactor fuel pellet. It was about as big as my pinkie, and the fuel rod is about the diameter of my pinkie, but 12 feet long. In a lot of ways, it is like spaghetti. It is just as flexible as spaghetti, but of course it is 12 feet long. And there are thousands of these nuclear fuel rods inside a nuclear reactor. A nuclear reactor is not anything but a glorified pressure cooker. A pressure cooker cooks at 15 pounds. A nuclear reactor cooks at 1,000 pounds. But essentially they are the same thing: they are designed to hold really hot water and not to leak. http://www.emfnews.org/
