B-Rent Posted March 12, 2011 Share Posted March 12, 2011 I'm more interested in the status of their nuke plants at this point. http://twitter.com/s...shima%20nuclear If I had to take a lethal rad dosage, I want a mega-dose.

Scott747 Posted March 12, 2011 Share Posted March 12, 2011 Hard to tell what is reliable right now. Twitter messages were breaking out about the fuel rods being exposed at the #1 reactor of the Daiichi plant and now Reuters is saying Japaneses nuclear authorities are claiming there is a high possibility of a meltdown. http://twitter.com/reutersflash Link to comment Share on other sites More sharing options...

Dunkman Posted March 12, 2011 Share Posted March 12, 2011 Koyodo reporting: BREAKING NEWS: Fukushima nuke plant might be experiencing nuclear meltdown http://english.kyodonews.jp/ Ok, so I'm fairly knowledgeable about weather, have a layman's understanding of earthquakes, and really could not know less about nuclear power plants. In a modern plant is there some sort of containment system for a meltdown or is it pretty much guaranteed to be a horrible situation? Link to comment Share on other sites More sharing options...

In a modern plant is there some sort of containment system for a meltdown or is it pretty much guaranteed to be a horrible situation? The containment vessel has 4'+ thick walls. They are designed to withstand a direct impact from a 747. But, with enough pressure, and vessel will breach eventually. These rods are 2000 degrees plus when meltdown occurs. http://en.wikipedia.org/wiki/Nuclear_safety_systems Link to comment Share on other sites More sharing options...

SmokeEater Posted March 12, 2011 Share Posted March 12, 2011 Why aren't any of the US cable news channels breaking into this and talking about it? Fox is talking about it now. Saying official has said even if there is a meltdown, it will not effect people beyond a 6 mile radius. Who knows where they are getting those numbers from.

In a modern plant is there some sort of containment system for a meltdown or is it pretty much guaranteed to be a horrible situation? Based on the design and everything I have read. The meltdown should be contained in the containment vessel. However, not everything always goes as planned. :-\ Link to comment Share on other sites More sharing options...

B-Rent Posted March 12, 2011 Share Posted March 12, 2011 I never studied chernobyl. Did it affect greater Europe? I know the area surrounding the plant is still uninhabitable. But what about the extended areas, 10's and 100's miles out? Link to comment Share on other sites More sharing options...

Ed Lizard Posted March 12, 2011 Share Posted March 12, 2011 Not a nuclear engineer, but I did use to operate 550 Mw pressurized water reactors before I went to college. In an area prone to massive earthquakes, they shopuld have had redundant backups to provide reactor cooling. An almost failsafe system has the heat exhangers/steam generators positioned in such a way hot water leaves the reactor going in an upward direction, cools, and sinks back to the reactor establishling flow without pumps. Natural circulation. Trident submarines can operate near half power without running reactor coolant pumps as a noise reducing feature.

This is just one of many parts of the whole earthquake disaster. While related to the earthquake the potential of an actual reactor melting down is rather significant and this thread would quickly take away from the impacts of the earthquake/tsunami. Just a thought and at this point it's hard to really know the level of this so called 'meltdown' so it could be jumping the gun. Link to comment Share on other sites More sharing options...

Wiki... http://en.wikipedia....ral_circulation My understanding (from media reports) is that they did, but they did not plan for the tsunami. Their back up power genrators were taken out by the water, they were placed above the level of the highest recorded wave they knew of. Link to comment Share on other sites More sharing options...

jburns Posted March 12, 2011 Share Posted March 12, 2011 Good old CNN. "Coming up next we ask a weather expert about the ring of fire and why its so dangerous". Maybe tomorrow they can bring in a geologist to explain the 10 day GFS. Link to comment Share on other sites More sharing options...

Gives credence to some of the twitter reports with the rods being partially exposed and the rush to raise the water level. Link to comment Share on other sites More sharing options...
