According to the reports, the Japanese are using all equipment available to pump sea water into the reactor building and cool the plant. As you know, sea water contains an incredible wealth of mineral elements, the most import of which is sodium. Sodium and water are incredibly corrosive, especially at high temperatures, such as those found in a nuclear power plant that is melting down.
Experts believe that this move has destroyed the last vestiges of electronic equipment in the reactor room. All forms of automated or electronic control should be lost as a result of this move. This means pumping seawater into the reactor room is the last-last-last ditch move. It's a 3-2 pitch in the bottom of the 9th.
This is some rather scary shit folks. Four out of five the Japanese nuclear plants are on red-alert right now. The only good word we have is that the radiation level around these plants has been declining over the past several hours. We don't know how much.
