“My understanding is that the situation has become desperate enough that they apparently don’t have the capability to deliver fresh water or plain water to cool the reactor and stabilize it and now, in an act of desperation, are having to resort to diverting and using sea water,” he said.

Boron, a chemical element, was being added to the water “to sort of stymie other potential nuclear reactions,” he said.

But, he acknowledged to reporters in a conference call, “There’s a lot that we don’t know about what’s happening with these reactors. It’s trying to piece together a picture where you’re dealing with just a few pieces of the puzzle.”

Another expert said enough was known to conclude that Saturday’s nuclear events in Japan rank high on the list of similar incidents. “If this accident stops right now it will already be one of the three worst accidents we have ever had at a nuclear power plant in the history of nuclear power,” said Joseph Cirincione, an expert on nuclear materials and president of the U.S.-based Ploughshares Fund, a firm involved in security and peace funding.

He said only the 1979 partial meltdown of a reactor core at the Three Mile Island nuclear plant in Pennsylvania and the 1986 Chernobyl disaster in the Soviet Union were worse.

So there you have it. This is a VERY serious situation, not only for Japan, but for wherever this radiation cloud floats. Your government may not tell you the complete truth. No surprises there.
