In the press conference of 1/24/2012, Tepco announced they are going to solidify the bottom of sea with the mixture of clay and concrete.
They are planning to start it from early February, end it by April.
It is not to spread concrete to cover the sea ground but cover it with heavy clay slowly so hot particles in the sea will not come up. The areas around intake of reactor 1 ~ 6 will be covered.
They still have not assessed the influence for the marine environment. After the press conference, MEXT released the data of contamination level on of sea ground. Ag-110m has been measured constantly from December. 1350_012514 Iori Mochizuki
Japanese experts believe the bottom of the ocean could also yield precious metals such as silver and gold and supplies of what they see as a potential next-generation fuel -- methane hydrate, also dubbed "fire ice".
Japan, which has long been one of the world's largest importers of industrial materials, is believed to have abundant underwater resources estimated to be worth about 200 trillion yen ($2 trillion), the Yomiuri said.

I don't understand .. AG-110m is an isotope of silver.
This would mean that the nuclear lava has become so hot that it's actually colloidializing silver out of the seawater..

Tepco just stuck a camera down reactor one or two, I can't remember which, apparently that was supposed to be the safest one. They found very little coolant, and they didnt find the melted goo. It was missing. I knew it was missing right from the very start.
And the Mox, that was very valuable and made a profit, there is n't even the slightest chance that Plutionium wasn't in ALL THE REACTORS.

I have a couple of questions. I understand clay can mechanically hold down particles, but can clay protect against radiation? Won't the clay itself become radioactive? What good would it do to seal anything in an earthquake zone as active as Japan?
