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.

Is this a sneaky way to use up all the contaminated ashes? To use them and radiative sludge for concrete..and then dump it into the ocean? Sure hope thats not the idea..to use the radioactive materials -soil, sludge, rocks, radioactive new condo materials,whatever –in the concrete mix. Wish this was not the first thing that came to mind when reading “concrete”….
“BURY the radiation, sounds so final!”
They better also plan on doing the same thing to TOKYO Harbor and EVERY OTHER PLACE THEY are dumping radioactive waste!
TEPCO – if you really are concerned about the hot particles in the sea, how about NOT RELEASING HIGHLY CONTAMINATED WATER INTO THE SEA in the first place.
They could be trying to stop more than just settled hot particles from moving about. They may be trying to stop hot particles seeping up into the sea from underground tunnels and whatever is still in them. They could be trying to reinforce the sea bed so that it does not collapse like old coal mines do. Something very … fishy… is going on, if you ask me.
I appreciate the information provided here, sad as it appears to me. The sea floor is such an important factor in maintaining the overall health of our oceans. Capping the sea floor is like covering the earth with asphalt thus disrupting all natural activity within the soils being covered. I am fearful that this cement more likely then not will be radioactive as well making it far more damaging then asphalt.
