Horrible. :smith:
[QUOTE=blazingfly;28550366]Even if it does go, we're looking at a Three Mile Island type failure, which released less radiation into the atmosphere than eating a banana would give you.[/QUOTE] God, I hope this is true.
Reuters says that the level of radiation inside the plant doesn't require worker evacuation yet.
[QUOTE=blazingfly;28550413]Reuters says that the level of radiation inside the plant doesn't require worker evacuation yet.[/QUOTE] Wow bullshit
[QUOTE=Kill001;28550511]Wow bullshit[/QUOTE] All they have to do is get the generators back online, and the problem is basically sorted, unless all the emergency cooling systems were also damaged in the quake, in which case there really isn't a lot you can do.
[QUOTE=blazingfly;28550539]All they have to do is get the generators back online, and the problem is basically sorted, unless all the emergency cooling systems were also damaged in the quake, in which case there really isn't a lot you can do.[/QUOTE] The line between the generators and the reactor coolant system is damaged, and there are probably coolant leaks as well.
[QUOTE=blazingfly;28550366]Even if it does go, we're looking at a Three Mile Island type failure, which released less radiation into the atmosphere than eating a banana would give you.[/QUOTE] Technically it would only be a problem if it causes a pressurized explosion and the reactor hall collapses, revealing the exposed core. But I'm sure it's built better than the CNPP. It is built better than the CNPP, right?
[QUOTE=Scar;28548502]Well, a meltdown would suck for millions, but would also be a good laugh for this sadistic fuck right here [editline]11th March 2011[/editline] No srls I hope nothing happens[/QUOTE] That's what I call a German sense of humor.
[QUOTE=archangel125;28550565]The line between the generators and the reactor coolant system is damaged, and there are probably coolant leaks as well.[/QUOTE] There should be a completely separate system of cooling systems called the 'ECCS' - Emergency Core Cooling System, of which most modern plants have up to four divisions. Each division is technically capable of independently cooling the core, and each division contains up to six individual subsystems using multiple different ways to cool the core. If the lines to every single one of those subsystems is cut, then :ohdear:

It might be bad, but it is very unlikely to be as bad as Chernobyl.
This really is making me feel like that architect guy from Titanic who was all like "But it's unsinkable!" and died standing in front of the clock.

Even with a steam explosion occurring within the reactor core, there is a good chance the reactor casing will survive unharmed. The Three Mile Island NPP survived a huge hydrogen explosion almost unscathed.
[QUOTE=TrouserDemon;28550612]Yes, they have proper containment facilities. It might be bad, but it is very unlikely to be as bad as Chernobyl.[/QUOTE] Yea, the core would probably melt and make a couple of cracks here and there if massive pressure starts to happen, but I'm sure it would be more like TMI than Chernobyl. It could probably leak in the reactor hall and damage some parts of the plant, tho.
[QUOTE=archangel125;28550565]The line between the generators and the reactor coolant system is damaged, and there are probably coolant leaks as well.[/QUOTE] Surely a set of jump leads would do to get the pumps juiced up? [editline]11th March 2011[/editline] You know, enough to actualy bridge the gap?
[QUOTE=Fatal-Error;28550774]Surely a set of jump leads would do to get the pumps juiced up?[/QUOTE] I dunno, there are like three independent generators in NPPs, with the final safety measure being batteries. They should have power...
[QUOTE=blazingfly;28550793]I dunno, there are like three independent generators in NPPs, with the final safety measure being batteries. They should have power...[/QUOTE] Even if the cables are fucked, they could expose the terminals and bodge something together between?
[QUOTE=Fatal-Error;28550806]Even if the cables are fucked, they could expose the terminals and bodge something together between?[/QUOTE] This could be what they're trying to do at the moment, but the cables are probably deliberately hard to access to prevent anyone from intentionally sabotaging them.
And I imagine they require heavy duty cabling as I doubt the pumps are small.
I just seen on Sky News on TV, but apparently, they have restored power to the plant...Not too sure though, can't find any online sources to confirm this.
Yeah, not really. Doesn't work like that. Its not like jump-starting a car.

[B]JUST IN:[/B] They're considering of releasing the steam inside the control rods cooling thing to lower the pressure; of course the release of radiation is inevitable but the radiation is filtered (?)
[QUOTE=Kill001;28550876][B]JUST IN:[/B] They're considering of releasing the steam inside the control rods to lower the pressure[/QUOTE] Heheh. Kill, you're a bit late there. They were considering that hours ago.
[QUOTE=Kill001;28550876][B]JUST IN:[/B] They're considering of releasing the steam inside the control rods to lower the pressure[/QUOTE] Won't it be the same as having a radioactive leak? Unless it won't be extremely well controlled?
[QUOTE=Kill001;28550876][B]JUST IN:[/B] They're considering of releasing the steam inside the control rods to lower the pressure[/QUOTE] So this means that it aint going to explode?
[QUOTE=Kill001;28550876][B]JUST IN:[/B] They're considering of releasing the steam inside the control rods cooling thing to lower the pressure; of course the release of radiation is inevitable but the radiation is filtered (?)[/QUOTE] Pretty sure that's also some old news.
Dunno, the university professional stated that it is a possibility as of now, but the info is outdated considering that he said that the radiation level at the time was, "8 times above normal"
[QUOTE=blazingfly;28550539]All they have to do is get the generators back online, and the problem is basically sorted, unless all the emergency cooling systems were also damaged in the quake, in which case there really isn't a lot you can do.[/QUOTE] They can't get them online since they're all flooded.
