“Both experts agree capping the damaged reactors with concrete is not an option . . . “
Well then why is a billion dollar cement pumper being sent to Japan? The article I read said after its done it will be toast because it will be so radioactive. I can only assume they are going to pump cement on the reactor with it. Otherwise why would it be radioactive?
Maybe they will build a tall retaining wall?
The large pumps are needed for their volume and for their long booms. They will first be pumping water. Then if needed, they will be present to switch to concrete, from what I have read. At least that is the cover story. They are also moving a gigantic barge to the facility that can store 18,000 tons of water in a holding sea pen. They have no idea what they will do with all that radioactive water however. My guess is a mysterious leak will eventually be spotted in the barge.
