[QUOTE=GhostPhoster;28563627]Excuse my ignorant ass but what does a meltdown entail?[/QUOTE]
Bumpdabump, I'm curious as well.
Trust me, it will be fine.

Basically the nuclear material continues heating up and melts the place down.
Hence 'meltdown'.

I read somewhere that supposedly, Chernobyl's core is continuing to melt it's way down, why is that?
They are now having a new press conference.
[QUOTE=ewitwins;28563836]I read somewhere that supposedly, Chernobyl's core is continuing to melt it's way down, why is that?[/QUOTE]
Because the material is still radioactive, and so via nuclear fission, is still hot.
They're in the process of flooding it with sea water now.
I would like to divide your attention to a nice video that has been posted in the video subforum that esplains Three-Mile Island's accident in March 1979. Again, I would like to point out that in history it's the most similar to what has happened at Fukushima at this time, not Chernobyl.

Nuclear fission is still going on in Chernobyl's core. What they did was fully withdraw the Control Rods and left some more fuel rods in the reactor, and it got to hot. There is no way to just stop nuclear fission right in its track, there is only hope when it is going to stop.
Just luckily the russians weren't stupid and put the critical mass of uranium in the core.
The nuclear material heats up and melts a hole in the earth until it reaches the earth's core.

At that point, demons come out of the hole.

The moment you hit ground water.
Sigh.
A meltdown occurs when the material in the reactor core reaches a high enough temperature that it melts. It does [i]not[/i] entail [i]the entire reactor[/i] melting; the core is usually contained in a vessel which will hold in the molten core without spreading radiation outside of the reactor housing. It destroys the core for all intents and purposes, but does not necessarily prove any more harmful.
Chernobyl's meltdown was such a big thing because of the design of the reactor; as it was built to be refueled (and to breed weapons-grade material), the top of the reactor was removable so that fuel could be extracted or inserted. Due to a steam explosion caused by unsafe procedures (negligence, etc), the top of the reactor was blasted off, and resulting explosion damaged the reactor building and caused all the horror.
Modern nuclear power stations do not use the design that was used for Chernobyl (RBMK); they use designs which are much safer and have inbuilt safety measures which prevent a runaway reaction of the type which destroyed Chernobyl Reactor 4.
I heard something about 4.5-7 mSv.

It's okay, if we're quick enough we can forge adamantine weapons to fight them off.

That's pretty good, you would generally need to be exposed for one hour at 200x that amount to experience nausea.
So, what happened? D:
I don't know I haven't heard anything new in a while.
Anyone with access to some Japanese news know anything about it?
[editline]12th March 2011[/editline]
I don't know if this apparent silence is good or bad.

No news is good news.
News came in that this was a hydrogen explosion and did not affect the core at all. It simply blew the walls off the building and another hydrogen explosion won't be happening again as it's no longer a confined space.
While I'm still getting reports of a possible meltdown, anything now will be a "safe meltdown" in that they will be able to contain it to the pressure vessel. They have since gotten two pumps online (they had a "round peg, square hole" issue regarding wiring the replacement one up supposedly) and the use of seawater to cool the core down has dropped the core temperature and pressure and secondary reactions are also now falling. We are now getting close to declaring the crisis over.

Isn't this old news?
I've already heard about the hydrogen explosion, possible meltdown, using seawater to cool it down and that it's most likely going to be all right.

The more recent news is that it IS going to be alright not that it MIGHT. I just am not participating in the other thread as it's turning into a bashfest.

There's no longer 100+ users viewing this thread. Please tell them that they were able to contain this situation.
(Just woke up and wanted to check up real quick)
Me to my work colleague : "Hey man, did you hear about the nuclear accident in Japan?"
Colleague : "Yeah, I think so. Was that what caused the tsunami?"
:what:
The last report I saw, a few hours ago said the level at the plant was 1050 micro Sv, slightly less dosage than having a CAT scan, or the dosage you would receive from cosmic rays in a year if you lived at a high altitude. It's not dangerous, but does exceed national limits. Most people have been evacuated beyond 12km from the plant anyway.
so nothing is critical anymore? :dance:
[QUOTE=daijitsu;28567866]so nothing is critical anymore? :dance:[/QUOTE]
Well there's been quite a bit of radiation leaked, but it doesn't seem like it's going to become a major disaster.
I'm not sure I'd like to live too close to the plant for a few years though.
