Is Nuclear Plant Crisis in Japan "Stable," Really?

NOT

Here is what skynews is reporting. All of these data points have been made separately but now the mainstream media is only too happy to spin the return of electricity to reactors #5 and #6 as "solving" the problems. NO @#$% Way is that true!

here is the report:

"After stringing a new power line to the plant from the electric grid, company officials reported on Saturday that they had reconnected coolant pumps in reactor Nos. 5 and 6 and restored the flow of water to the spent fuel cooling pools in those buildings. In the day since, temperatures in those pools have returned to near normal.

"But those two pools had not been considered a significant threat. Authorities are much more concerned about reactors No. 2 and No. 3 and the spent fuel pool at No. 4.


The reactor containment vessel at No. 2 may be cracked and venting some radioactive gases into the environment.

Reactor No. 3 is the only reactor at the site that contains plutonium in the fuel rods and its escape would be extremely dangerous because it is carcinogenic in even minute doses.

And the spent fuel pool at reactor building No. 4 is thought to have boiled dry, allowing the fuel rods to heat up and become damaged, also releasing radioactivity into the environment.

The nuclear cores inside the reactors are usually covered in water, but the top halves of the cores in reactors 1, 2 and 3 were exposed to air for at least several days, according to reports from the International Atomic Energy Agency and other sources.


Even if those cores are resubmerged, they may have experienced permanent damage that would make them more difficult to keep cool, Lyman said.

For instance, he said, if the exposed portions of the fuel rods have swelled due to heat, the gaps between them may now be too small to pass enough water to cool them.

In addition, when the ziconium cladding surrounding the cores was exposed to air, it may have oxidised and become so brittle that radioactive fuel particles could have escaped through cracks....


'These cores may not be as easily cooled as if they were undamaged,' Lyman said.
