And now they are in they're fourth day without power and water. HELL it could be months before they have power? IF they don't have a meltdown in any of the reactors. HOw long does it take to clean up a disaster like this and get a Nuke back online???
HOLY......Hell.
ABC News - Japan Earthquake: before and after

My dad is a retired AF officer, and has a degree in Nuc Engineering. We were talking about this yesterday, and it was a very interesting discussion, but bottomline, the reactors that have had the partial meltdowns are done. Just put a barrier around them and let them sit for a loooooong time. The good news though is that in all the cases so far, the actual containment vessels have reportedly held. The outer shells that blew up were outer structures, not primarily responsible for limiting radioactivity, although they did serve that function for any extraneous radiation.

Another note, as to the difference to Chernobyl, just as an interesting aside, is that Chernobyl used a graphite moderator, which collects radiation and slows the nuclear reaction. When it was on fire, the graphite moderators actually caught on fire, and spewed the radiation up high in to the atmosphere, thus causing the extensive following damage. These reactors, and all united states reactors use a water based moderator, so if it there is a meltdown, the radioactive particles are hooked to steam, which while it needs to be released to avoid pressure buildup, will dissipate quickly, and will not harm the primary containment vessel.

Even with all that, let's hope that these reactors are neutralized quickly, and the surrounding population cared for.

What I don't understand is the cooling down issue and why it takes so long. Did your dad talk about that?

It takes so long because even when they shut them down they keep generating heat. Kind of like when you turn off your oven and it takes a while to fully cool down.

I feel much the same way about my earlier joke but at first it didn't seem like it was the huge of a disaster.

They should have written in their contracts that they aren't allowed to Twitter. I would say it's amazing that so many people are stupid as ****, but our country does rank 14th in the world in education scores. Not to mention idiots like her probably majored in some two bit degree so she could bounce a ball.

Absolutely disgusting. I cant believe people think like this after semi recent disasters here like 9/11 and Katrina.

Ironically, her alma mater had a women's squad that was infamously derided by shock jock Don Imus a few year's back.

What exactly is there to loot? If you are in the recycling/timber business I could see looting being worthwhile. It doesn't help that grocery stores are giving away good and water either. Also electronics exposed to water is worthless.

I realize they retain heat but they must also keep producing heat for some period because of how much time has passed and they are still that hot. The only other thing I could think of is that they have to lower the temp slowly to prevent cracking issues.

Something tells me it is not that easy and you may need a good understanding of nuclear physics to truly appreciate how it "cools" itself.
