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.
Ah kk. Yeah I didn't post it up because it's too heavily speculated at this point, but it is one of the possibilities.

Holy crap.... I just viewed the OP again. They have THAT many plants in Japan?

That's insane. I really hope they get things under control. Even if there's no explosion there's still risk of environmental affects.

The United States has 104 operation plants, France has 58, and Japan 55.

On an interesting sidenote China has 13 in operation, 27 under construction, 50 planned, and 110 proposed.

OP Updated - A spokesman for the Japan Atomic Power Company has explained that one of the cooling system pumps at its Tokai nuclear power plant failed because of the tsunami. "We then manually stopped one of our cooling systems," Masao Nakano told the AFP news agency. "But the other cooling systems and other pumps are working well, and temperatures of the reactor have continued to fall smoothly.

Looks like things are really stable at the Tokai power plant. I'll keep posting about it until the emergency status is lifted from the plant.

World Earthquake Risk Map



World Earthquake Risk Map With Nuclear Plants


You have to admit though. At the end of the day it's taken an extreme disaster to bring about these failures. The Fukushima plants were close to being decommissioned, with Reactor #1 supposed to go down toward the end of march if I remember correctly(Fukushima Reactors #7 and #8 were are currently in development and were planned to take over as the older BWR reactors were decommissioned). Anyway these are very old plants compared to current technology and Japan is more prepared for disasters like this that pretty much anyone else.
