EPTIts more likely that the molten nuclear material burns its way through the bottom of the reactors reaching the ground water.
Still, unimaginable impact on environment

Thread is about the various issues surrounding Japan in the aftermath of the recent earthquake. Don't bring the shit side of the internet to the thread, and post with the realization that this thread is very important, and very real, to your fellow members. Do not post speculative and unconfirmed news you saw on TV or anywhere else. Generally the more dramatic it sounds the less likely it's true. | ||

How much material could there be? Hopefully the radioactive materials from supplies have been evacuated from the area. Other qestions seems to be quite difficult for me. But, say living in Moldova means ~0% risk for you. | ||

Hopefully the radioactive materials from supplies have been evacuated from the area. There are several tonnes of radioactive material used in a Nuclear power plant. In Tchernobyl for example the incident released several hundret tonnes of radioactive material. Iod-131; Caesium-137; Caesium-134; Strontium-90 and the "real long term" isotopes of Plutonium, Neptunium and Curium. But as said before - we can't have a Tchernobyl even in the worst case. | ||

The worst case is the fuel rods melt and form a pool at the bottom of the reactor, this would stop them being able to control the reaction in any way. If this happens then the fuel will likely melt through the bottom of the pressure vessel, releasing superheated water with it. The water at this temperature can split into hydrogen and oxygen, causing explosions. Fires fueled by the unstoppable reaction can last for days or weeks, with the smoke spreading radioactive material to the winds. This is the worst case ofcourse. There will never be any nuclear bomb sort of explosion, the fuel isn't refined to the point where it can explode, all the fuel will do is melt its way into the ground. | ||

It's really striking that a first world country like Japan which is perhaps the most equipped to deal with an earthquake in the entire world can be brought to its knees like this. I hope this if nothing else makes the rest of the world reconsider where they stand in terms of building regulations, etc. Props to Japan for dealing with it as well as they are and I can only hope the rest of the world is funneling in aide. Nothing prepared them for a tsunami that huge which took out every life supporting services such as electricity which is essential in keeping the reactors cool so stop blaming that they were not equip for earthquake more importantly tsunami wasn't one of the disasters that they were trained in combating for . | ||

The powerplant survives a 9.0 Earhtquake which sounds like WTFHOW?... And then everything gets bad because it gets flooded by a Tsunami, which you ckinda should expect at the coast? I would imagine it would break down to the Earthquake, not to the floodwave... | ||

The chain reaction stops but the reaction from the radioactive isotopes carries on, without control rods or coolant this is uncontrolable, which is what I said. My worst case scenario was pretty much exactly the same as that proffesor described  | ||

It was save for an earthquake up to 8.25 but this one was 9. The power plant was damaged by the quake, the tsunami only made it worse. | ||

While you can build to resist an earthquake with incredible engineering, a Tsunami is not that easy to stop, not only does it have a incredible force of water, but the debree that comes with it is also quite destructive. I believe the Tsunami destroyed(or damaged) a certain cooling generator(correct me on this one) which is causing problems with the Nuclear reactors as they can not cool down right now | ||
