There is a huge difference. A 'slow' nuclear fission liquidizes and vaporizes the fuel, spreading out and greatly reduces the amount nuclear reactions. Nuclear bombs require extremely precise time to split the atoms before the fuel flies apart.

Do you expect to see a mushroom cloud over Japan if a meltdown occurs?

no idiot. That is entirely my point.

I find it highly funny that Shiloh thought I meant an H-bomb is going to explode from a reactor melt down. That's what he was calling you out on. All I was saying is that in an H-bomb, fission is used to acquire fusion.

EDIT PS Also, even from what you describe, the only difference is... timing of the reaction. So where is that HUGE difference you keep talking about? :)

Poor meber, try again.

According to this:

Fukushima I Nuclear Power Plant - Wikipedia, the free encyclopedia


Reactor 3 is bigger than Reactor 1. Also has a different designer.

It's also a generation newer.

yeah confirmed by korean media estimated 10,000 dead. just a couple hundred like lgbr said

Fusion requires extremely high temperatures. Very high temperatures in a fission reactor cause a loss of containment and dispersion of fuel, thus limiting further temperature increases. In other words, in order to get fusion, you have to be really trying for it and as such, I find the claims of fusion to be extremely dubious.

Yeah, the timing difference between a second and a nanosecond is ****ing huge.

[Golbez-RG-] 03-13-2011 05:59

And thats exactly why I said I highly doubt fusion is occurring. :)

Lol you are really trying hard though, aren't you?

[Golbez-RG-] 03-13-2011 06:09

Also if we have a full loss of containment, radiation would be blown 1000s of miles away, like what happened in Chernobyl since it had no such containment building. Nobody has really seen or experienced a melt down on a reactor with a containment building yet, in theory it should just melt straight down.

Given the population along the coast, it will be a miracle if the figure is not over 100k

Shiloh 03-13-2011 06:17

you said "A runaway fission reaction can make that happen. How do you think it happens in an H-bomb?". I assert that this is a stupid statement since it can't realistically melt down fast enough to get the millions of degrees required for fusion. I also assert that its so far removed from the H-bomb that the comparison is stupid. It sounds like this is the view you are trying to furiously backpeddle toward.

Code4 03-13-2011 06:20

calm down member you sound like a lil kid begging for attention

[Golbez-RG-] 03-13-2011 06:27

Lol ****in trolls...

Gotta love when they say the exact same thing as you did, after you did, and tell you that you're stupid.

I can't believe people actually make troll accounts for this reason, really need to get a life if that's how you get your jollies, lol.

No this won't happen at all, dude.

If there is a loss of containment there won't be a huge ejection of radiation into the atmosphere like there was in Chernobyl. That plant exploded when the core melted through the RCV down to a cooling tank underneath the reactor. The Fukushima plant doesn't have anything like that, it's several feet of concrete and steel designed to contain the slagged core.

What caused the massive fallout was not the explosion at Chernobyl anyways. When the core was exposed to air the graphite moderator caught fire and started spreading radioactive debris into the surrounding area and the atmosphere. Fukushima doesn't use have graphite. It's a light water reactors which means water serves as both a coolant and as a neutron moderator; if the water goes away, the nuclear reaction stops. An runaway reaction like Chernobyl is not possible with a light water reactors; thanks to their negative void coefficient. There will not be any sort of self-sustaining feedback loop like what happened at Chernobyl.

They have shut down the reactor cores and they have the control rods in place. what this means is the temperature levels are nowhere near those the ones found in normal operation. Right now it's generating decay heat and this is causing the pressure problems. Decay heat has to be managed by cooling systems, and since those systems were messed up in the Earthquake/Tsunami it's not being managed properly.

So when this began they were looking at the posibility that the water would boil off completely, stopping the reaction but allowing the decay heat to cause the fuel core to melt. This could have meant the slagged core would melt through the bottom of the RCV into the concrete below. The end result would have been a huge cleanup inside the outer contanment building but little to no release of radiation anywhere else.

Right now they have decided to focus on scrapping the entire reactor and filling the whole thing with sea water. This will destroy the reactor permanently yes but it will also keep the cores from melting further and shut down the reaction. The financial toll is gonna be huge ($500M-$1B) but this is one of the worst case scenarios and it's resulted in no major loss of life or danger to the country.
