Anand Naidoo, CCTV anchor: From what we know about what is going on at the plant right now, is this going to get worse?
Dr. Janette Sherman, radiation expert: I hate say this, but yes I think it will. And my concern is the enormous amount of radioactive material flowing with the water into the Pacific Ocean. And we know that the ocean flows northward along Alaska and down the coast of Canada and the United States. And I think it probably will imperil the entire Pacific Ocean, and the the sea life thats in it.

Naidoo: The radioactive content in this water does it dissipate, or does it just stay in the water all the time?
Sherman: Well both cesium and strontium have a half-life about thirty years. It takes 10 half-lives for each of these isotopes to decay down to nothing. We contaminate the plankton, and thats eaten by shrimp and oysters and fish and mammals. And as most of these move up the food chain they get concentrated. Particularly strontium-90 gets concentrated in the bones.

Ya, we be shit now, momma.

edit to say: I didn't mean you were "obfuscating, lying and distorting." Sorry.

(3,888 posts)But, while this may be true, we have a responsibility to see that other plants are safely closed and that alternate sources of energy are developed, to replace the energy being supplied by nukes.
I thought the interview was a good one, because Dr. Janette Sherman did not pretend that all was going to be fine.
She seemed honest in her concern for the future and for wanting others to understand the danger we face.

(28,979 posts)The scientists have been warning us:
Steven Starr Director of the Clinical Laboratory Science Program at the University of Missouri/Senior Scientist at Physicians for Social Responsibility said:
The Japanese basically lied about what happened with the reactors for months. They said they were trying to prevent a meltdown, when in fact they knew within the first couple of days Reactors 1, 2, and 3 at Fukushima Daiichi had melted down, and they actually melted through the steel containment vessels.
So there was a worst case scenario that they were trying to hide, they even knew that at that time enormous amounts of radiation were released over Japan and some of it even went over Tokyo [...]
The melted core cracked the containment vessel, there really is no containment. So as soon as they pump the water in it leaks out again.

(33,982 posts)Yes, it melted through the reactor pressure vessel. (Steel)
There's currently no evidence that it melted through the steel lined, 6 foot thick concrete containment. It would be in the water table if it had. The containments may only be leaking from the connection points to the steam suppression pool torus, or the torus itself on a couple of them, based on the locations of the explosions. The corium may well be sitting in place in the catchment of the containment. The radiation outside the containment can be explained by fuel/corium sediment carried out by the panicked efforts to slam water through to cool it. So in a way, it may have partially escaped the containment, but the bulk of it must be inside the containment, or we would have three enormous radioactive plumes of steam for months and months boiling up around the buildings.
The RPV isn't the Containment. It ALSO contains the fuel, when operating properly, and that clearly failed. But the Containment appears to be keeping the corium inside. (Excluding possibly some radioactive sediment/maybe some fuel pellets from shattered fuel rods)

(28,979 posts)You say would, I say could. When you say there is "no evidence it melted" but "it may have partially escaped from the containment" it does not exactly inspire confidence that the situation is in any way under control or anyone any closer to knowing the true situation.

(33,982 posts)TEPCO completes photographing the containments, one by one, from every side. A difficult, but technically possible feat. Likely the only way we'll ever know. Sort of like that amazing photo in the subbasement of Chernobyl, below the reactor, that shows corium 'magma' that solidified, pouring out of a pipe.
Hot as hell, but they got the photo somehow...

The planet is going to need it.
It's almost as if it would be better to just like the thing go up in a nuclear explosion!
Don't we have anybody running this planet that can fix this? Or at least talk about it!
