[QUOTE=sp00ks;28579624]It melts down and releases a lot of radiation, it doesn't blow up. Anyways, isn't it under control now anyways?[/QUOTE] Read the thread...
[QUOTE=GhostPhoster;28579555]I posted this exactly in another thread and I was rated dumb. :bravo:[/QUOTE] Well it is dumb.
i live near a nuclear research facility :cool:
[QUOTE=lolnubs;28575830]That's [b]if they overheated[/b]. Not a full-scale meltdown[/QUOTE] [B]They're the same fucking thing.[/B] [quote]thermo-nuclear explosion would still fuck shit up.[/quote] Well, good thing that's physically impossible. To clarify, a thermonuclear explosion is what you get in a hydrogen bomb, where the temperature rises to [B]millions and millions of degrees[/B], enough for hydrogen nuclei to overcome the electrostatic repulsion holding them apart, so they can get close enough to each other for the Strong Nuclear Force to take effect, fusing them into helium and releasing shittons of energy. [B]This cannot happen with the nuclear reactor.[/B]
So are they starting to get this under control?

It amuses me everyone still thinks the reactor is going to vaporise in a gigantic nuclear explosion that will decimate the entire country. lrn2nuclearphysics
[QUOTE=blazingfly;28580420]It amuses me everyone still thinks the reactor is going to vaporise in a gigantic nuclear explosion that will decimate the entire country. lrn2nuclearphysics[/QUOTE] Won't be a nuclear explosion, just nuclear fallout, which is worse.
The whole area is gonna be abandoned for atleast 20 years cause of this bullshit...bah.
[QUOTE=lukepker;28580468]Won't be a nuclear explosion, just nuclear fallout, which is worse.[/QUOTE] Except no, that will not happen either.
[QUOTE=MoarFunz;28580481]The whole area is gonna be abandoned for atleast 20 years cause of this bullshit...bah.[/QUOTE] ITT: People make assumptions and are misinformed about nuclear power. As the [b]nuclear engineer[/b] quote said on the [b]last page[/b]: [quote]The RPV is [b]surrounded by a containment facility designed from the ground up to withstand everything short of hydrogen bombs[/b]. Given the semi-spherical distance from the RPV an explosion would have to travel to break through the containment vessel, it is fundamentally impossible (given the energy density the RPV is capable of containing) for there to be straight up "radioactive smoke" or such getting outside of containment. [b]The containment building is constructed to prevent EXACTLY this emergency.[/b][/quote]
I heard over the news that radiation was leaked, not alot, but it was leaked, which means the place is unsuitable for living.
[QUOTE=MoarFunz;28580525]I heard over the news that radiation was leaked, not alot, but it was leaked, which means the place is unsuitable for living.[/QUOTE] No it doesn't. It's over the national safe limit, yes, and it will certainly bring down property prices near to the epicentre. But you can still live there.
Fucking Again?
[QUOTE=MoarFunz;28580525]I heard over the [B]news[/B] that radiation was leaked, not alot, but it was leaked, which means the place is unsuitable for living.[/QUOTE] Well there's your problem. Did they provide sources from MIT guys coming to the front desk of the news explaining their tinfoil hat theories, because that's exactly what happened over here. They were wrong about every fact [editline]13th March 2011[/editline] Every. Single. One.

...wow, I've never known anyone who was sterile before! :v:

[QUOTE=lukepker;28580468]Won't be a nuclear explosion, just nuclear fallout, which is worse.[/QUOTE] Just snort some potassium iodine
[QUOTE=MoarFunz;28580525]I heard over the news that radiation was leaked, not alot, but it was leaked, which means the place is unsuitable for living.[/QUOTE] There was a cesium leak next to the reactor and the radiation levels at the nuclear plant have went over government standard, but that's the only place where they have spotten an unusuitable radiation level.
Guy on AJE's talking about total nuclear meltdown - a core gone critical and let loose will melt through everything (concrete, crust) until it reaches the earth's core :O
News is now reporting an emergency at another nuclear plant, at Onagawa, about 100KM away from Fukushima....
[QUOTE=lolnubs;28578657]Could have installed some kind of air filters couldn't they? Or just wear gas masks to bed... IMO anti-nuclear people are totally dumb, a light-water reactor like this one is actually a fucking good thing then... So long as they can stop any disasters, and prove to the world that despite the facility being bashed by earthquakes and suffering a semi-LOCA, then maybe all of the coal power plants will be replaced by these reactors. I mean, WA is "nuclear free". So we have a power-plant spewing thousands of tonnes of CO2, where a simple little reactor like this could provide cleaner power, and at least there has been some time to evacuate everyone IN CASE of this reactor failing... [editline]13th March 2011[/editline] Well, if they put water on it, the fucker will just get hotter, so they need to dope that shit with boron. They can't dig under the reactor or anything, they can only watch, wait and hope that they can cool it down before it actually melts through anything. But at the current rate, the top of the control rods have melted... wow. The cores are going into meltdown, let's hust hope they can stop the thing before the whole core is liquid. But i don't like the idea of sodium chloride being present in the makeshift coolant, you know what happens when you boil away seawater. You get salt. If any salt deposits start forming up, there is potential for even more problems :frown:[/QUOTE] You do know they aren't putting water on it to keep it cool, but to absorb neutrons in the case of a full meltdown. Putting sea water on your reactor is counted as a last resort. [editline]13th March 2011[/editline] [QUOTE=doonbugie2;28578877]Atleast it wont be like Chernobyl. Nuclear disasters suck.[/QUOTE] Well if all the reactors that have gone to emergency state meltdown it could be many time worse. [editline]13th March 2011[/editline] [QUOTE=bravehat;28579095]Better idea. Use boron doped sea water. HEY WAIT THEY'RE ALREADY DOING THAT! Who'da thunk it? v:v:v[/QUOTE] Well they did use a mixture of boron and sand at the chernobyl plant, it just wasn't enough to prevent a disaster. [editline]13th March 2011[/editline] [QUOTE=bravehat;28578746]The reaction was already killed wuth boron control rods, they're just trying to keep it cool now so that a spontaneous fission reaction doesn't kick off, and they're using boron doped seawater as a coolant right now and as far as i know they're directly applying it since the cooling system is fucked.[/QUOTE] They weren't killed, just brought down the a reasonable level.

That's why they've mixed boric acid into the water (because boron is a very good neutron absorber, and doesn't really act as a moderator).

[QUOTE=MoarFunz;28580525]I heard over the news that radiation was leaked, not alot, but it was leaked, which means the place is unsuitable for living.[/QUOTE] The majority of what has been leaked is 16N or 18F; the former won't even make it off the property, the latter floats on air and is gone in 2 hours.
"Oh Chernobyl was an isolated case that would NEVER happen again we should use nuclear power as much as possible everywhere forever!" :downs:
[QUOTE=POLOPOZOZO;28581985]"Oh Chernobyl was an isolated case that would NEVER happen again we should use nuclear power as much as possible everywhere forever!" :downs:[/QUOTE] Looks like someone is extremely incapable of reading.
[QUOTE=POLOPOZOZO;28581985]"Oh Chernobyl was an isolated case that would NEVER happen again we should use nuclear power as much as possible everywhere forever!" :downs:[/QUOTE] There is nothing to say this will end up like Chernobyl, in fact if they manage to keep these reactors under control it really does prove how reliable and safe they are.
