an op was posted about the plume rising at reactor # 3
3 possibilities of why the plume was rising were detailed in the article the op linked too
http://www.democraticunderground.com/10024261981
Possibility 1: a meltdown is taking place
The Reactor 3 fuel storage pond still houses an estimated 89 tonnes of the plutonium-based MOX nuclear fuel employed by the reactor, composed of 514 fuel rods.
Ever since the explosion Tepco has been concerned that if the spent fuel storage pond dries out, the intensely radioactive spent fuel rods would melt down and produce further significant radioactive emissions.
Possibility 2: corium has reached groundwater
Reactor 3 itself contained 566 fuel rods, and has experienced a complete meltdown. The location of the molten fuel, known as corium, is unknown, but it may have burnt its way through the reactor base and entered the underlying soil.
This would also produce steam as the hot corium came into contact with groundwater, while also releasing radioactive contamination to make its way into the Pacific Ocean.
Possibility 3: rainwater on stray fuel elements / Reactor
An alternative explanation is that the steam plumes could be caused by stray fuel pellets and reactor rod fragments which themselves produce significant amounts of heat coming into contact with rainwater percolating through the damaged and roofless structure.

the anti woo peops came into thread,declared it woo and stopped discussion,so my question is are there other more likely scenarios?
which of these 3 is the most likely? (let's hope it is # 3 since that is the least harmful)
or why are these 3 scenarios completely false ?

(16,184 posts)I write this letter to you with a heavy heart, for today I have seen brother take up arms against brother. Such senseless argument, such meaningless flame, such tired pettiness. Today we stand victorious on the fields of St John's Wort, though for many of my brothers, it stands a hallow victory.

(111,245 posts)and that leaves two possibilities: either it has melted through the floor of the reactor or water is entering the chamber and being turned into steam. I find the second most likely, although the first will happen eventually.
DU has gained a few pro nuclear flacks who will dismiss any posts suggesting problems with nuclear power as "woo" or worse.

(9,651 posts)has that happened before?
is there anyway we can know what the consequences might be?
i can admit i am no scientist but isn't #2 commonly refered to as "china syndrome"?

(111,245 posts)I think they'd be picking up increased radiation in ground water if it had happened. While TEPCO hasn't been forthcoming with much information so far, I think they might have mentioned it if it had occurred--or some of their international team trying to figure out how to stabilize the whole business and keep it from getting worse would spill the beans.

(9,651 posts)i am still a little surprised at what gets attention or discussion here...what struck me as odd with the op in question was the bashing the author of the least deadly opinion (#3)

(9,651 posts)The Nazca Lines Located in South America, etched into a high plateau in Perus Nazca Desert, a series of ancient designs stretching more than 50 miles has baffled archaeologists for decades. Along with simple lines and geometric shapes, they include drawings of animals, birds and humans, some measuring more than 600 feet across.
Because of their colossal size, the figures can only be appreciated from way up in the air and there is no evidence that the Nazca people, who inhabited the area between 300 B.C. and 800 A.D., invented flying machines. According to ancient alien theorists, the figures were used to guide spaceships as they came in for a landing, and the lines served as runways

(62,444 posts)Curiosity about a subject is a good start to finding out what has actually already been figured out.
Gothic cathedrals, viewed from above, are laid out in the shape of a cross. It's quite striking to look at Google earth pictures of them. Medieval Europeans didn't have airplanes, or aliens, either. It turns out that people like to make big things for purely artistic and spiritual purposes.
The racist assumption is, of course, that it was perfectly normal for Europeans to make big things that only make sense from a then-impossible elevation, but South American natives were somehow too stupid.
Ancient people were every bit as intelligent, and included folks just as clever as the most clever person walking the earth today. We did not become innately more intelligent in the last few thousand years. We did start writing stuff down to make it easy for each generation to jump start "stuff they know". However, in the absence of knowledge about metallurgy and other aspects of material science, it turns out that ancient people were really really good - and had a lot of experience - at doing things with rocks. In cultures which had a relatively good handle on the basics of food cultivation, they also had a LOT of time on their hands to figure out how to do cool stuff with rocks.
