[emsnews] Japan: TEPCO predicts possible "china syndrome". - Page 4

post #31 of 242
Frankly the situation has never been remotely good over there. Of course this is an internet forum and you can take this with a grain of salt but I know people on the ground over there working on the clean up. It has been a mess since day one. But people just kept saying I was fear mongering.

My prayers are with the people of Japan.

I really hope they get a handle on this thing before it gets catastrophically worse. My in-laws all live over there, and I actually like my in-laws.

I'm with you, I really hope they're able to get a handle on the situation, prayers to the brave people also trying to help in the clean-up as well.

In short, the melted slag that used to be the reactor core is still sustaining the reaction, and is extremely hot as a result. So hot that it is eating through the containment vessel and the concrete beneath it. Once it enters the ground and reaches groundwater, since the molten fuel is @ ~3000C, it will cause the groundwater to flash-boil and explode, in effect, creating a water based volcano. This in turn will cause a massive release of radioactive material into the atmosphere (possibly comparable to the Castle Bravo test or worse), and will poison the land around the reactors for centuries. And then there is the problem with the fallout, which will get blown across the pacific to the states, at which point the media turns the fear knob to 11.

This is what is known as a "China Syndrome" meltdown, and is the worst case scenario possible.

So do we have any more people claiming nuclear is safe or can we safely assume that stupid talk is over with for the rest of human existence?

Nuclear power is completely safe, there have only been a small number of nuclear disasters in history compared to the large number of coal plant explosions which happen on a daily basis, taking out entire cities and rendering them uninhabitable for decades.

A large number of coal plant explosions have happened on a daily basis and have taken out entire cities for decades? LoL what are you talking about. Can you name a single city made uninhabitable by JUST a coal plant explosion? I mean if it happens daily, you should be able to list at least 365 dead cities. thumbsdownsmileyanim.gif

Think about what you just said for a second. If Chernobyl had hit a water vein, it would have made most of Europe uninhabitable. If Fukushima hits a water vein it could take out most of the pacific. In the first video posted, Japan admitted that they had an INSTANT 100% melt down of AT LEAST core #1. There was a group of workers who took many times the lethal dose in order to work on the plant while they dumped seawater on the core and let that same radioactive water wash out to sea b/c without it they would have lost northern Japan.

Oh and unlike your exaggerative coal fairy tale, radiation issues from a nuclear plant can easily take 10,000 years or more to fix.

We can build much stronger facilities today.

Yeah, instant core meltdown, workers having to suicide themselves to save northern Japan, reactors melting through concrete to the dirt while making radioactive steam that's 2x the lethal dosage in 1 hr and having the possibility that the reactor could hit a water vein and erupt like a radioactive volcano is DEFINITELY a vote for nuclear.kookoo.gif

Natural disasters happen. A lot. All it would take is for 1 plant to be in the middle of a singular hurricane/tornado/tsunami/earthquake/flood/war to radiate a 2000 mi radius for the next 1000 years.

Oh and while we can build facilities better, it's not by much. It's not like Fukushima was a mud hut. New reactors cost BILLIONS to make and like ANYTHING that's made for-profit, it's guaranteed that corners will be cut somewhere. At some point, human greed or human error will come into play.

That said, there exists experimental tech which could render that problem moot.
You're referring to TWRs but nothing is working at this point.

not that must be very bad news!! when you put it that way. what f it melts through the world?

This is true, most contracts are sold to the lowest bidder.

Nuclear disasters are anything but small. When one reactor can make an entire country or more uninhabitable for thousands of years... it's not really "completely safe".

Yes it took a lot for this to happen, but that doesn't change the fact that it DID happen, and the worst is likely still to come.

I'm just a fatso computer nerd so excuse the question. If they use control rods that absorb/disrupt alpha particles to stop a reaction in progress, why can't they just throw a bunch of those in this molten mess to stop slow reaction? headscratch.gif
