Link? I've been looking for information that said something like that since the crisis started and I've found nothing to back it up and nobody is claiming it. Even the scaremongering websites aren't carrying anything like that.

I haven't heard of them finding pieces of a tube.

International blowback on the nuclear crisis starting to occur - The crisis has renewed concern in other countries about the safety of atomic power. In Germany, Chancellor Angela Merkel said it represented a turning point for the world. She said that safety standards at her own country's nuclear power stations would now be reviewed. In the United States, Senator Joe Lieberman said Washington needed to put the brakes on the development of nuclear power plants until lessons were learned from what had happened in Japan.

Too right ! If we cannot forget about Atomic power then at least make it safer.

I'm just worried that it'll set back development of new reactors and plants by years if not decades. Given the projected growth in demand for energy over the next 40 years we're going to need some sort of bridge between coal, oil and gas and renewable resources. Nuclear is the most likely power source to fill that gap. However maybe this incident will also create greater demand for renewable energy development.

Op Updated - Tokai nuclear power plant: A report submitted to the Ibaraki prefectural government by the Japan Atomic Power Company said that one of the two pumps being used to cool the water of a suppression pool for the plant's nuclear reactor had stopped working, according to the Kyodo news agency. However, the other pump was still working and there was no problem with cooling the reactor, the prefectural government said. All control rods were set in completely at the reactor, it added.

Looks like Tokai is stable for the time being. Hopefully it stays that way.

Quite wrong! Modern Nuclear plants are very safe. It took an earthquake, one of the top 10 strongest ever recorded, to even bring one near meltdown. Most plants will never experience something like this! And they are currently designing new plants based on Thorium, rather than Uranium, which are even safer than current generation plants. We need to put more money into nuclear power, not take it away because of an accident occurring about once every 20 years. That's a safety record much higher than any coal or oil or other "natural" plants can boast. How many people are dying right now because of coal smoke aggravated emphysema? How many are dying from radiation sickness? Hint, I can tell you that there is a large disproportion.

In the end, nuclear is much safer than anything we have today, excepting things like solar power.

I think that they ought to look into new energy production methods, Nuclear in the long run is not safe, whichever way you look at it. It may be Cleaner until you have to dispose of the waste but its not safe. Even a natural disaster proves that.

Before the explosion, Japan's nuclear agency had said that radioactive caesium and iodine had been detected near the number one reactor. The agency said this could indicate that containers of uranium fuel inside the reactor may have begun melting.

The tubes that hold the uranium melt at 2200 degrees C, while the uranium fuel itself melts at 3000 degrees C. Its good that they did not find uranium, but you would expect them to find cesium and iodine in the coolant if the tubes were melting.

Coolant levels dropped as steam was vented, exposing the top of the core to air/steam. Without water to carry away heat produced by short-lived fission byproducts, the temperature of the exposed bits of core increased. Sometime after the cesium and iodine were detected, seawater was pumped in.

Seawater remains irradiated longer than pure water, making clean-up more expensive.
